RESUMO

AIM: To understand the perceived helpfulness and acceptability of a bespoke psychological therapy service for registered nurses. The service provided a free and confidential specialist mental health service to all healthcare professionals, including nurses and nursing students. DESIGN: An exploratory study using a descriptive qualitative approach. METHODS: A purposive sample of 20 registered nurses accessing a bespoke psychological therapy service in Wales participated in audio-recorded semi-structured interviews in January 2022. Transcribed data were analysed using reflexive thematic analysis. RESULTS: Four interrelated themes were identified from the data analysis: COVID [SARS-CoV-2] changed things; You're a nurse, you're human; I've got 'me' back; and pretty close to miracle workers. CONCLUSION: Participants attempted to live up to an idealized image of a nurse, generating self-stigmatizing beliefs that negatively affected their mental health. The psychological therapy service enabled participants to put their roles into perspective, that is, separate themselves from their role, be vulnerable, and develop confidence and adaptive coping strategies. Participants valued the minimal barriers and ease of access to support. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The complex relationship between nurse identity and the challenges of the workplace needs to be central to nurse education. Nurses can benefit from rapid access to a timely, confidential, and independent self-referring psychological therapy service. IMPACT: This qualitative study explored the helpfulness and accessibility of psychological support for nurses. The main themes were that COVID changed things; You're a nurse, you're human; I've got 'me' back; and pretty close to miracle workers. The findings will impact how nurses are supported in the United Kingdom and worldwide. REPORTING METHOD: This report adheres to the standards for reporting qualitative research (SRQR). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMO

Selective, one-step C-H activation of fatty acids from biomass is an attractive concept in sustainable chemistry. Biocatalysis has shown promise for generating high-value hydroxy acids, but to date enzyme discovery has relied on laborious screening and produced limited hits, which predominantly oxidise the subterminal positions of fatty acids. Herein we show that ancestral sequence reconstruction (ASR) is an effective tool to explore the sequence-activity landscape of a family of multidomain, self-sufficient P450 monooxygenases. We resurrected 11 catalytically active CYP116B ancestors, each with a unique regioselectivity fingerprint that varied from subterminal in the older ancestors to mid-chain in the lineage leading to the extant, P450-TT. In lineages leading to extant enzymes in thermophiles, thermostability increased from ancestral to extant forms, as expected if thermophily had arisen de novo. Our studies show that ASR can be applied to multidomain enzymes to develop active, self-sufficient monooxygenases as regioselective biocatalysts for fatty acid hydroxylation.

RESUMO

OBJECTIVES: To disseminate and assess the level of acceptability and applicability of the European Alliance of Associations for Rheumatology (EULAR) recommendations for patient education among professionals in rheumatology across Europe and three Asian countries and identify potential barriers and facilitators to their application. METHODS: A parallel convergent mixed-methods design with an inductive approach was used. A web-based survey, available in 20 different languages, was distributed to health professionals by non-probability sampling. The level of agreement and applicability of each recommendation was assessed by (0-10) rating scales. Barriers and facilitators to implementation were assessed using free-text responses. Quantitative data were analysed descriptively and qualitative data by content analysis and presented in 16 categories supported by quotes. RESULTS: A total of 1159 completed the survey; 852 (73.5%) were women. Most of the professionals were nurses (n=487), rheumatologists (n=320), physiotherapists (n=158). For all recommendations, the level of agreement was high but applicability was lower. The four most common barriers to application were lack of time, lack of training in how to provide patient education, not having enough staff to perform this task and lack of evaluation tools. The most common facilitators were tailoring patient education to individual patients, using group education, linking patient education with diagnosis and treatment and inviting patients to provide feedback on patient education delivery. CONCLUSIONS: This project has disseminated the EULAR recommendations for patient education to health professionals across 23 countries. Potential barriers to their application were identified and some are amenable to change, namely training patient education providers and developing evaluation tools.

RESUMO

BACKGROUND: Forced migration is at record levels, leading many European countries to seek to limit immigration or control access to public services. The UK has introduced upfront healthcare charging for overseas patients, with exceptions for certain groups and services. Confusion over these regulations amongst healthcare professionals risks care being inappropriately delayed or denied. This is pertinent within sexual and reproductive health and HIV care where sensitivity and timely management are essential. METHODS: We conducted a survey exploring clinicians' knowledge of healthcare charging regulations and terminology, their confidence and experience on this topic and their ability to evaluate case-based scenarios. RESULTS: Of 343 valid responses, 78% reported encountering refugees, asylum seekers or undocumented migrants in practice. Only 39% felt confident in their understanding of healthcare entitlements. Terminology was appropriately defined by 66%, but only 53% of case-based scenarios were answered correctly. About 71% reported needing further training in this area, and many comments indicated a desire for educational resources. CONCLUSIONS: SRH and HIV professionals demonstrated limited knowledge of healthcare charging for migrants, despite working with these groups. This could undermine their ability to deliver appropriate advice and care to these potentially vulnerable patients. Training and support for these staff is essential.

RESUMO

Enzyme catalysis is gaining increasing importance in synthetic chemistry. Nowadays, the growing number of biocatalysts accessible by means of bioinformatics and enzyme engineering opens up an immense variety of selective reactions. Biocatalysis especially provides excellent opportunities for late-stage modification often superior to conventional de novo synthesis. Enzymes have proven to be useful for direct introduction of functional groups into complex scaffolds, as well as for rapid diversification of compound libraries. Particularly important and highly topical are enzyme-catalysed oxyfunctionalisations, halogenations, methylations, reductions, and amide bond formations due to the high prevalence of these motifs in pharmaceuticals. This Review gives an overview of the strengths and limitations of enzymatic late-stage modifications using native and engineered enzymes in synthesis while focusing on important examples in drug development.

RESUMO

Marine phytoplankton experience a wide range of nutrient and light conditions in nature and respond to these conditions through changes in growth rate, chlorophyll concentration, and other physiological properties. Chlorophyll fluorescence is a non-invasive and efficient tool for characterizing changes in these physiological properties. In particular, the introduction of fast repetition rate fluorometry (FRRf) into studies of phytoplankton physiology has enabled detailed studies of photosynthetic components and kinetics. One property retrieved with an FRRf is the 'single-turnover' maximum fluorescence (FmST) when the primary electron acceptor, Qa, is reduced but the plastoquinone (PQ) pool is oxidized. A second retrieved property is the 'multiple-turnover' fluorescence (FMT) when both Qa and PQ are reduced. Here, variations in FmST and FMT were measured in the green alga Dunaliella tertiolecta grown under nitrate-limited, light-limited, and replete conditions. The ratio of FmST to FMT (ST/MT) showed a consistent relationship with cellular chlorophyll in D. tertiolecta across all growth conditions. However, the ST/MT ratio decreased with growth rate under nitrate-limited conditions but increased with growth rate under light-limited conditions. In addition, cells from light-limited conditions showed a high accumulation of Qb-nonreducing centers, while cells from nitrate-limited conditions showed little to none. We propose that these findings reflect differences in the reduction and oxidation rates of plastoquinone due to the unique impacts of light and nitrate limitation on the stoichiometry of light-harvesting components and downstream electron acceptors.

RESUMO

BACKGROUND: Blood eosinophil counts and history of exacerbations have been proposed as predictors of patients with chronic obstructive pulmonary disease (COPD) who may benefit from triple therapy (inhaled corticosteroid, long-acting ß2-agonist and long-acting muscarinic antagonist). METHODS: In a retrospective cohort analysis we examined the profiles of COPD patients from the UK Clinical Practice Research Datalink (CPRD) and US Optum Clinformatics™ Data Mart (Optum) databases with reference to exacerbation frequency and blood eosinophil distribution. RESULTS: Of the 31,437 (CPRD) and 383,825 (Optum) patients with COPD, 15,364 (CPRD) and 139,465 (Optum) met the eligibility criteria and were included. Among patients with ≥2 exacerbations and available eosinophil counts in the baseline period (CPRD, n = 3089 and Optum, n = 13414), 17.0 and 13.3% respectively had eosinophil counts ≥400 cells/µL. Patients with ≥2 exacerbations or eosinophil count ≥400 cells/µL during first year, exacerbated at least once (CPRD, 82.8% vs Optum, 80.6%) or continued to have eosinophil count ≥300 cells/µL (76.8% vs 76.5%), respectively in the follow-up year. In both years, a higher variability in the number of exacerbations and eosinophil count was observed in patients with one exacerbation and eosinophil counts between 300 and 400 cells/µL; patients with eosinophil count < 150 cells/µL had the lowest variability. Approximately 10% patients had both ≥2 exacerbations and eosinophil count ≥300 cells/µL across the databases. CONCLUSION: A high variability in blood eosinophil counts over two consecutive years was observed in UK and US patients with COPD and should be considered while making treatment decisions. A small proportion of COPD patients had frequent exacerbations and eosinophil count ≥300 cells/µL.

RESUMO

Unmodified reperfusion therapy for acute myocardial infarction (AMI) is associated with irreversible myocardial injury beyond that sustained during ischemia. Studies in experimental models of ischemia/reperfusion and in humans undergoing reperfusion therapy for AMI have examined potential beneficial effects of nitric oxide (NO) supplemented at the time of reperfusion. Using a rigorous systematic search approach, we have identified and critically evaluated all the relevant experimental and clinical literature to assess whether exogenous NO given at reperfusion can limit infarct size. An inclusive search strategy was undertaken to identify all in vivo experimental animal and clinical human studies published in the period 1990-2014 where NO gas, nitrite, nitrate or NO donors were given to ameliorate reperfusion injury. Articles were screened at title and subsequently at abstract level, followed by objective full text analysis using a critical appraisal tool. In twenty-one animal studies, all NO treatments except nitroglycerin afforded protection against measures of reperfusion injury, including infarct size, creatinine kinase release, neutrophil accumulation and cardiac dysfunction. In three human AMI RCT's, there was no consistent evidence of infarct limitation associated with NO treatment as an adjunct to reperfusion. Despite experimental evidence that most NO treatments can reduce infarct size when given as adjuncts to reperfusion, the value of these interventions in clinical AMI is unproven. Our study raises issues for the design of further clinical studies and emphasises the need for improved design of animal studies to reflect more accurately the comorbidities and other confounding factors seen in clinical AMI.

RESUMO

Triglycerides and cholesterol are essential for life in most organisms. Triglycerides serve as the principal energy storage depot and, where vascular systems exist, as a means of energy transport. Cholesterol is essential for the functional integrity of all cellular membrane systems. The endoplasmic reticulum is the site of secretory lipoprotein production and de novo cholesterol synthesis, yet little is known about how these activities are coordinated with each other or with the activity of the COPII machinery, which transports endoplasmic reticulum cargo to the Golgi. The Sar1B component of this machinery is mutated in chylomicron retention disorder, indicating that this Sar1 isoform secures delivery of dietary lipids into the circulation. However, it is not known why some patients with chylomicron retention disorder develop hepatic steatosis, despite impaired intestinal fat malabsorption, and why very severe hypocholesterolemia develops in this condition. Here, we show that Sar1B also promotes hepatic apolipoprotein (apo) B lipoprotein secretion and that this promoting activity is coordinated with the processes regulating apoB expression and the transfer of triglycerides/cholesterol moieties onto this large lipid transport protein. We also show that although Sar1A antagonizes the lipoprotein secretion-promoting activity of Sar1B, both isoforms modulate the expression of genes encoding cholesterol biosynthetic enzymes and the synthesis of cholesterol de novo. These results not only establish that Sar1B promotes the secretion of hepatic lipids but also adds regulation of cholesterol synthesis to Sar1B's repertoire of transport functions.

RESUMO

BACKGROUND: The Additional Roles Reimbursement Scheme (ARRS) was set up to recruit 26 000 additional staff into general practice by 2024, with the aim of increasing patient access to appointments. Despite the potential benefits of integrating ARRS practitioners into primary care, their implementation has not always been straightforward. AIM: To explore the challenges and enablers to implementation of the ARRS including its impact on primary and secondary care systems. DESIGN AND SETTING: Qualitative interview study with ARRS healthcare professionals and key professional stakeholders involved in staff education or scheme implementation across three integrated care systems in England. METHOD: Participants (n = 37) were interviewed using semi-structured individual or paired interviews. Interviews were audio-recorded and transcribed. Data were analysed using framework analysis until data saturation occurred. RESULTS: Using framework analysis, 10 categories were identified. Three were categorised as successes: staff valued but their impact unclear; multiple and certain roles maximise impact; and training hub support. Seven were categorised as challenges: scheme inflexibility; creating a sustainable workforce with career progression; managing scope and expectations; navigating supervision and roadmap progression; infrastructure and integration challenges; ARRS roles impact on wider systems; and tensions and perspectives of existing staff. CONCLUSION: Most ARRS staff felt valued, but the scheme broadened expertise available in primary care rather than reducing GP burden, which was originally anticipated. Some PCNs, especially those in areas of high deprivation, found it difficult to meet the population's needs as a result of the scheme's inflexibility, potentially leading to greater health inequalities in primary care. Recommendations are proposed to optimise the effective implementation of the primary care workforce model. Further research is required to explore administrative role solutions, further understand the impact of health inequalities, and investigate the wellbeing of ARRS staff.

RESUMO

BACKGROUND: Treatment options available for meningoencephalitis of unknown origin (MUO) in dogs are suboptimal, and currently, no single treatment protocol appears to be superior. OBJECTIVES: Compare neurological deterioration rates at 7 days between dogs with MUO treated with corticosteroids alone or combined with cytosine arabinoside (CA) continuous rate infusion (CRI) and compare clinical deterioration and survival at 30 and 100 days. ANIMALS: Sixty-nine dogs with magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) features or both compatible with MUO. METHODS: Parallel, blinded, randomized controlled trial. Simple randomization into 2 treatment groups: 4 mg/kg/day prednisolone (or dexamethasone equivalent) for 2 days or 200 mg/m2 CA CRI over 8 hours plus 2 mg/kg/day prednisolone. Blinding of the treatment protocol was carried out using reversible redaction of clinical records, and treatment failure was defined as deterioration of neurological assessment or death. Using intention-to-treat analysis, proportions failing treatment at 7, 30, and 100 days were compared using Fisher's exact test. All-cause mortality at 100 days was compared using Kaplan-Meier survival curves. RESULTS: Thirty-five dogs were allocated to corticosteroid only, and 34 dogs were allocated to combined CA CRI and corticosteroid. Proportions failing treatment at 7, 30, and 100 days were 7/35 (20%), 9/35 (26%), and 15/35 (43%) in the corticosteroid-only group and 8/34 (24%), 11/34 (32%), and 23/34 (68%) in the corticosteroid and CA CRI group. All-cause mortality at 100 days was not significantly different between groups (P = .62). Clinically relevant treatment-related adverse effects were not observed. CONCLUSIONS AND CLINICAL IMPORTANCE: We found no difference in outcome between corticosteroid monotherapy and combined cytarabine CRI and corticosteroid therapy at 7, 30, and 100 days after diagnosis in dogs with MUO.

RESUMO

OBJECTIVE: Many clinically extremely vulnerable rheumatology patients have only recently ceased shielding from COVID-19, while some continue to minimise in-person contact. The objective of this study was to understand the impact of shielding and associated support needs in patients with rheumatic conditions and to understand how rheumatology teams can meet these needs both currently and in future pandemics. DESIGN, PARTICIPANTS AND SETTING: The study was conducted in the Southwest of England using a case-study design. The participants were 15 patients with rheumatic conditions who were advised to shield and/or chose to shield at any time during the COVID-19 pandemic. METHODS: Qualitative data collected via telephone and online semi-structured interviews and analysed using reflexive thematic analysis. RESULTS: Fifteen interviews were conducted. Three main themes represent the data:'Just shove them over there in the corner' captures changes in patients' self-perception. They felt different to most other people, vulnerable and left behind. The initial sense of shock was followed by a sense of loss as changes became long term.'A long and lonely road' captures patients' psychological isolation due to a perceived lack of understanding and support. This included having to prove their health status and justify their shielding behaviours, which impacted their relationships. At times, they felt abandoned by their healthcare providers.'You can't just flip a switch' captures the difficulty of getting back to pre-pandemic normal after shielding. Patients did not recognise themselves physically and mentally. They wanted to collaborate with health professionals and identified the need for specific guidance to support their recovery. CONCLUSION: Patients are dealing with lasting physical and mental effects from shielding and consequences of delayed healthcare. Health professionals need time and resources to ask about patients' well-being, identify their health needs and refer/signpost to appropriate sources of support.

RESUMO

Dietary fat is an important source of nutrition. Here we identify eight mutations in SARA2 that are associated with three severe disorders of fat malabsorption. The Sar1 family of proteins initiates the intracellular transport of proteins in COPII (coat protein)-coated vesicles. Our data suggest that chylomicrons, which vastly exceed the size of typical COPII vesicles, are selectively recruited by the COPII machinery for transport through the secretory pathways of the cell.

RESUMO

BACKGROUND: First Contact Physiotherapists (FCPs) were introduced to reduce demands on GPs by providing improving access to expert musculoskeletal care. FCPs experience similar workplace stressors to GPs and there is an emerging concern that remote consultations are causing further impacts to their wellbeing. AIM: To explore the impact of remote consultations on FCPs. METHODS: A mixed methods sequential explanatory study with FCPs was conducted. An online survey measured the usage and impact of remote consultations. Semi-structured interviews explored the lived experiences of using remote consultations. RESULTS: The online survey was completed by 109 FCPs. A key benefit of remote consultations was patient convenience; perceived challenges included IT issues, poor efficacy, FCP anxiety, isolation, and increased workload. FCPs viewed remote consultations as a 'challenge' rather than a 'threat'. Nearly two thirds of the FCPs had not received relevant training, yet over half were interested. Follow-up interviews with 16 FCPs revealed 4 themes: (1) Remote consultations provide logistical benefits to the patient; (2) Compromised efficacy is the key challenge of remote consultations; (3) Challenges for FCPs working in areas of high deprivation; and (4) Remote consultations impact the health, wellbeing and work satisfaction of FCPs. CONCLUSIONS: Remote consultations offer a convenient alternative for patients, but may add to FCP stress particularly in areas of high socioeconomic deprivation. Further research is required to understand how remote consultations can be enhanced when communication barriers and lower levels of digital literacy exist. Continued monitoring of job satisfaction and resilience levels is important to ensure FCPs remain in their role.

RESUMO

Ingroup bias is often treated as the default outcome of intergroup comparisons. We argue that the mechanisms of impression formation depend on what information people infer from groups. We differentiate between belief-indicative groups that are more informative of beliefs and affect attitudes through ingroup bias and status-indicative groups that are more informative of status and affect attitudes through a preference for higher status. In a cross-cultural factorial experiment (Ntotal = 1,281), we demonstrate that when information about targets' multiple group memberships is available, belief-indicative groups affect attitudes via ingroup bias, whereas status-indicative groups-via preference for higher status. These effects were moderated by social-structural context. In two follow-up studies (Ntotal = 451), we develop and validate a measure of belief- and status-indicativeness (BISI) of groups. BISI showed expected correlations with related constructs of entitativity and essentialism. Belief-indicativeness of groups was a better predictor of ingroup bias than entitativity and essentialism.

RESUMO

ß-D-Galactofuranose (Galf) and its polysaccharides are found in bacteria, fungi and protozoa but do not occur in mammalian tissues, and thus represent a specific target for anti-pathogenic drugs. Understanding the enzymatic degradation of these polysaccharides is therefore of great interest, but the identity of fungal enzymes with exclusively galactofuranosidase activity has so far remained elusive. Here we describe the identification and characterization of a galactofuranosidase from the industrially important fungus Aspergillus niger. Analysis of glycoside hydrolase family 43 subfamily 34 (GH43_34) members via conserved unique peptide patterns and phylogeny, revealed the occurrence of distinct clusters and, by comparison with specificities of characterized bacterial members, suggested a basis for prediction of enzyme specificity. Using this rationale, in tandem with molecular docking, we identified a putative ß-D-galactofuranosidase from A. niger which was recombinantly produced in Escherichia coli. The Galf-specific hydrolase, encoded by xynD demonstrates maximum activity at pH 5, 25 °C towards 4-nitrophenyl-ß-galactofuranoside (pNP-ß-Galf), with a Km of 17.9 ± 1.9 mM and Vmax of 70.6 ± 5.3 µM min-1. The characterization of this first fungal GH43 galactofuranosidase offers further molecular insight into the degradation of Galf-containing structures.

RESUMO

AIM: To examine Registered Nurses (RNs') and nursing students' perspectives on factors contributing to moral distress and the effects on their health, well-being and professional and career intentions. DESIGN: Joanna Briggs Institute mixed-methods systematic review and thematic synthesis. Registered in Prospero (Redacted). METHODS: Five databases were searched on 5 May 2021 for studies published in English since January 2010. Methodological quality assessment was conducted in parallel with data extraction. RESULTS: Searches yielded 2343 hits. Seventy-seven articles were included. Most were correlational design and used convenience sampling. Studies were mainly from North America and Asia and situated in intensive and critical care settings. There were common, consistent sources of moral distress across continents, specialities and settings. Factors related to perceived inability or failure to enact moral agency and responsibility in moral events at individual, team and structural levels generated distress. Moral distress had a negative effect on RNs health and psychological well-being. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution to this systematic review.

RESUMO

BACKGROUND: HE is a common neurologic complication in cirrhosis associated with substantial disease and economic burden. HE symptoms are nonspecific and there are limited ways of identifying patients with cirrhosis at high risk of later developing HE. A risk score was previously developed to identify patients at risk of developing HE in a predominately male US cohort. Here, we evaluated the performance of the HE risk scores in a UK cohort study. METHODS: Health care records from Clinical Practice Research Datalink and linked Hospital Episode Statistics were used to select patients with cirrhosis who were diagnosed with HE, confirmed by a diagnosis code for HE or a rifaximin-α prescription. The index date was the date of incident cirrhosis. The study period was from January 2003 to June 2019. RESULTS: A total of 40,809 patients with cirrhosis were selected in the UK cohort, of whom 59% were male. A total of 1561 patients were diagnosed with HE. Applying the UK cohort to the baseline sensitivity risk cutoff (≥-11) from the US cohort provided a sensitivity of 92% and a negative predictive value of 99%. Within a longitudinal model, applying a sensitivity cutoff of ≥-3 to this cohort gave a sensitivity of 89% and a negative predictive value of 99%. CONCLUSIONS: Using data from the UK, the previously developed HE risk scores were found to be reliable for selecting those most likely to progress to HE in patients with liver cirrhosis. Despite the HE risk scores originally being estimated using the data from a predominately male US cohort, the scores were validated and found to be generalizable to female patients.

RESUMO

AIMS: The Outcome Measures in Rheumatology Trials (OMERACT) Remission in Rheumatoid Arthritis (RA) patient perspective working group has previously found that patients prioritised independence, pain, and fatigue as key domains of remission in RA. However, there is currently no clear definition of independence. Consequently, this scoping review aimed to explore how independence is represented in the RA literature. METHODS: A comprehensive search of the EMBASE, Medline, and PsycInfo databases was performed for publications that used independence or autonomy as a disease activity measure, description of disease in remission or treatment outcome. Papers were included if they involved adult participants and were written in English, with no restrictions on study design or publication year. Two reviewers (TK and AC, AT or BJ) independently screened the abstracts. A thematic approach was applied to derive common definitions and descriptions of independence. RESULTS: 660 articles were identified, of which 58 (25 qualitative, 28 quantitative, one mixed, and four reviews) met the inclusion criteria. 86% of total participants were female. Ten publications referenced remission. Independence took many forms; in addition to physical and functional capability, it was described in relation to work, social activities, autonomy in healthcare, and household activities. Four common themes describing independence were identified: 1. A return to a state before arthritis. 2. Being physically and functionally able. 3. A sense of freedom without needing to rely on others. 4. Having control over the organisation of one's life. CONCLUSION: Although independence is frequently mentioned in the RA literature, it has various meanings, lacks a consistent definition, and is a concept rarely applied to remission. It is multi-factorial, exceeding functional ability alone, and contextualised within sociodemographic and disease factors. This scoping review provides common descriptions of independence to inform future qualitative work towards the development of an outcome measure of independence for the assessment of RA in remission.
