RESUMO

OBJECTIVES: This mixed-methods systematic review aimed to identify and synthesize knowledge of the characteristics, content, and preferred format of information to support people with inflammatory arthritis (IA) to take methotrexate. METHODS: A literature search using MEDLINE, The Cochrane Library, Embase, CINAHL, PsychInfo, GreyEU, Web of Science and Open Dissertation was conducted to identify all studies published from 2000 to December 2022. Included studies detailed factors related to methotrexate (MTX) related information needs of people with inflammatory arthritis ≥ 18 years in English. Joanna Briggs Institute Guidelines (JBI) for convergent integrated mixed-methods systematic reviews were followed using validated tools for data extraction and quality. Data was analysed using reflexive thematic analysis. RESULTS: Thirteen studies (seven quantitative, two mixed-methods and four qualitative) were included involving 3425 adults, mainly female n = 2434 (71%), age 20-84 years. An overarching theme of a requirement for person-centred care was developed with three interlinking themes: 1: Accepting the need for treatment with MTX, 2: Concerns about taking MTX, 3: A need for tailored information and support. Limitations of the evidence were use of heterogeneous outcome measures and instruments to measure information needs. CONCLUSION: People with IA have individual, multi-faceted information, and support needs about MTX that are often unresolved when a one-size-fits-all approach is used. The findings can inform rheumatology training to support a person-centred approach to identifying and addressing specific needs, concerns and the development of consistent easy-to-understand accessible MTX information.

RESUMO

Cerebral malaria is an important cause of mortality and neurodisability in endemic regions. We show magnetic resonance imaging (MRI) features suggestive of cytotoxic and vasogenic cerebral edema followed by microhemorrhages in 2 adult UK cases, comparing them with an Indian cohort. Long-term follow-up images correlate ongoing changes with residual functional impairment.

RESUMO

We present the results of the 2022 Census of the Federation of Royal Colleges of Physicians of Edinburgh, Glasgow and London on whether physicians undertake research and the barriers they have encountered. 40% of physicians reported that they undertook research alongside their clinical work. Multivariate analysis of the responses showed that men were 1.6 times more likely to say they undertake research than women. The main barriers to undertaking research were having enough time, organisational factors and a lack of confidence. In this opinion piece we discuss some of the challenges and how they could be addressed.

RESUMO

INTRODUCTION: In May 2020 a virtual ward for COVID-19 patients seen at University College London Hospital (UCLH) was established. The aim of this study was to see if specific factors can be used to predict the risk of deterioration and need for Emergency Department (ED) reattendance or admission. METHODS: We performed a service evaluation of the COVID-19 virtual ward service at UCLH between 24/10/2020 and 12/2/2021. 649 patients were included with data collected on vital signs, basic measurements, and blood tests from their initial ED attendance, allowing calculation of ISARIC-4C mortality scores. Outcomes of interest were ED reattendance, facilitation of this by virtual ward physician, level of care if admitted, and death within 28 days of the first COVID-19 virtual ward appointment. Analysis was performed using Mann-Whitney U tests. RESULTS: Reattendance rate to ED was 17.3% (112/649) of which 8% (51/649) were admitted. Half of ED reattendances were facilitated by the virtual ward service. Overall mortality was 0.92%. Patients who reattended ED, facilitated by the virtual ward service, had a higher mean CRP (53.63 vs 41.67 mg/L), presented to ED initially later in their COVID-19 illness (8 vs 6.5 days) and had a higher admission rate (61 vs 39%). The mean ISARIC-4C score was higher in the reattendance group compared to the non-reattendance group (3.87 vs 3.48, difference of 0.179, p = 0.003). The mean ISARIC-4C score was higher in the admission group than the non-reattendance group (5.56 vs 3.48, difference of 0.115, p = 0.003). CONCLUSION: Identification of patient risk factors for reattendance following a diagnosis of COVID-19 in ED can be used to design a service to safely manage patients remotely. We found that the ISARIC -4C mortality score was associated with risk of hospital admission and could be used to identify those requiring more active remote follow up.

RESUMO

BACKGROUND: Necrotizing otitis externa is an invasive infection, affecting older patients, with significant associated morbidity. Despite this, there are no randomized controlled trials that address management, and therefore, treatment approaches may vary considerably. We describe the management and outcomes of 37 patients managed using a multidisciplinary treatment pathway for necrotizing otitis externa over a 5-year period. The pathway is based on a standardized antibiotic regime of 3 weeks of intravenous ceftazidime plus oral ciprofloxacin, followed by a further 3 weeks of ciprofloxacin. METHODS: This is a retrospective review of all patients diagnosed with necrotizing otitis externa since the introduction of our pathway in 2016. We include data on patient demographics, comorbidities, microbiology, length of stay, and length of antimicrobial treatment. Outcome data, including mortality, relapse and treatment failure, and adverse effects of treatment, are presented. RESULTS: The median age of our patients was 82 years. About 54% of patients had diabetes mellitus or another cause of immunocompromise. Pseudomonas aeruginosa was isolated in 68%. The median duration of inpatient stay was 9 days, and median treatment duration was 6 weeks. Of 37 patients, 32 were cured (86%), and of the remaining 5 patients, there were 2 mortalities unrelated to necrotizing otitis externa and 3 patients with recurrent infections due to anatomical abnormalities. CONCLUSION: We note favorable treatment outcomes when using a standardized multidisciplinary pathway and a 6-week course of antibiotic therapy.

RESUMO

Background: Specialist Community Practitioner (SCP) and Specialist Community Public Health Nurse (SCPHN) students are required to evidence their competency by the use of reflective practice as part of the NMC proficiencies. A reflective café trilogy comprising of three reflective teaching sessions was developed and introduced into a university programme to support and encourage alternative methods for deeper reflection within this student group. Aim: It was important for educators to evaluate if a reflective café met the student's needs and understand the usefulness of a 'reflective café' as a technique to support the process of reflecting on practice. Methods: Evaluation was undertaken using an online questionnaire. Findings: Students evaluated if the reflective café was useful for their own development and identified that the number of sessions met their developmental needs. Conclusion: The potential to develop alternative methods to reflect was recognised and the team plan to develop other reflective processes to support students in the future.

RESUMO

Oral nutrition supplements (ONS) are widely recommended for the management of unintentional weight loss in patient populations, long-term care residents, and community-dwelling older adults. Most marketed ONS are ultra-processed, with precision nutrition and aseptic composition, as well as convenience and availability, driving their selection. However, therapeutic effectiveness is mixed and the potential health risks of consuming ultra-processed ONS long-term in lieu of less-processed foods have received little attention. A diverse and balanced microbiota supporting immunity and wellness is maintained by a diet rich in plant-sourced foods. The implications of ultra-processed ONS displacing plant-sourced foods, and specifically the potential for undesirable impacts on the gut microbiota, require consideration. Most ONS are either devoid of fiber or are supplemented with isolated or purified fibers that may contribute to adverse gastrointestinal symptoms and appetite suppression. In contrast, the diversity of microbial-available, nondigestible carbohydrates, together with the array of phytochemicals found in plant-sourced foods, support microbial diversity and its resiliency. This review outlines the clinical dilemma of recommending commercial ultra-processed ONS vs nutritionally adequate (eg, high-energy/high-protein) foods and beverages that contribute to diet quality, maintenance of a diverse and stable gut microbiota composition, and support nutrition status and health. Ultra-processed ONS may fall short of expected health benefits, and overreliance may potentially contribute to the risk for patient and older adult populations because of the displacement of a variety of healthful foods.

RESUMO

Emerging evidence from human epidemiologic and animal studies has demonstrated that developmental anesthesia neurotoxicity could cause long-term cognitive deficits and behavioral problems. However, the underlying mechanisms remain largely unknown. We conducted an electrophysiological analysis of synapse activity and a transcriptomic assay of 24,881 mRNA expression on hippocampal tissues from postnatal day 60 (P60) mice receiving propofol exposure at postnatal day 7 (P7). We found that developmentally propofol-exposed P60 mouse hippocampal neurons displayed an E/I imbalance, compared with control mice as evidenced by the decreased excitation and increased inhibition. We found that propofol exposure at P7 led to the abnormal expression of 317 mRNAs in the hippocampus of P60 mice, including 23 synapse-related genes. Various bioinformatic analyses revealed that these abnormally expressed synaptic genes were associated with the function and development of synapse activity and plasticity, E/I balance, behavior, and cognitive impairment. Our findings suggest that the altered E/I balance may constitute a mechanism for propofol-induced long-term impaired learning and memory in mice. The transcriptomic and bioinformatic analysis of these dysregulated genes related to synaptic function paves the way for development of therapeutic strategies against anesthetic neurodegeneration through the restoration of E/I balance and the modification of synaptic gene expression.

RESUMO

Between 7 and 25 May, 86 monkeypox cases were confirmed in the United Kingdom (UK). Only one case is known to have travelled to a monkeypox virus (MPXV) endemic country. Seventy-nine cases with information were male and 66 reported being gay, bisexual, or other men who have sex with men. This is the first reported sustained MPXV transmission in the UK, with human-to-human transmission through close contacts, including in sexual networks. Improving case ascertainment and onward-transmission preventive measures are ongoing.

RESUMO

There is growing public health concern about the high prevalence of sleep deficiency in early childhood and the associated risk for sleep-associated poor health outcomes, including metabolic, cardiovascular, and mental health. The recent shift to conceptualize sleep health as a multidimensional construct, influenced by socioecological factors, highlights the potential role of sleep in health disparities. Understanding the development of sleep health and the emergence of sleep disorders in early life is a current priority in pediatric sleep research. Future behavioral sleep interventions should consider the multiple socioecological influences on children's sleep health and be tested using inclusive sampling methods.

RESUMO

The advent of human-induced pluripotent stem cell (iPSC)-derived three-dimensional (3D) cerebral organoids provides unprecedented opportunities of modeling human brains in states of health and disorder. Emerging data supports that cerebral organoids allow for more relevant in vitro systems for studying the human brain system and diseases than the current widely used 2D monolayer cell culture. Thus, the ability to isolate, culture, and maintain human brain cells from cerebral organoids is highly needed, particularly for studies on organoid-derived cell-type-specific signaling and their electrophysiological properties. Here we present a protocol to isolate and culture brain cells from 2-month human iPSC-derived cerebral organoids. The dissociation and plating of cells from organoids takes 3-4 h. The dissociated cells can be maintained in culture for up to at least 3 weeks. Some cells expressed the neuron-specific marker microtubule-associated protein 2 and exhibited spontaneous action potentials.

RESUMO

INTRODUCTION: Post-COVID-19 complications require simultaneous characterisation and management to plan policy and health system responses. We describe the 12-month experience of the first UK dedicated post-COVID-19 clinical service to include hospitalised and non-hospitalised patients. METHODS: In a single-centre, observational analysis, we report the demographics, symptoms, comorbidities, investigations, treatments, functional recovery, specialist referral and rehabilitation of 1325 individuals assessed at the University College London Hospitals post-COVID-19 service between April 2020 and April 2021, comparing by referral route: posthospitalised (PH), non-hospitalised (NH) and post emergency department (PED). Symptoms associated with poor recovery or inability to return to work full time were assessed using multivariable logistic regression. RESULTS: 1325 individuals were assessed (PH: 547, 41.3%; PED: 212, 16%; NH: 566, 42.7%). Compared with the PH and PED groups, the NH group were younger (median 44.6 (35.6-52.8) years vs 58.3 (47.0-67.7) years and 48.5 (39.4-55.7) years), more likely to be female (68.2%, 43.0% and 59.9%), less likely to be of ethnic minority (30.9%, 52.7% and 41.0%) or seen later after symptom onset (median (IQR): 194 (118-298) days, 69 (51-111) days and 76 (55-128) days; all p<0.0001). All groups had similar rates of onward specialist referral (NH 18.7%, PH 16.1% and PED 18.9%, p=0.452) and were more likely to require support for breathlessness (23.7%, 5.5% and 15.1%, p<0.001) and fatigue (17.8%, 4.8% and 8.0%, p<0.001). Hospitalised patients had higher rates of pulmonary emboli, persistent lung interstitial abnormalities and other organ impairment. 716 (54.0%) individuals reported <75% optimal health (median 70%, IQR 55%-85%). Less than half of employed individuals could return to work full time at first assessment. CONCLUSION: Post-COVID-19 symptoms were significant in PH and NH patients, with significant ongoing healthcare needs and utilisation. Trials of interventions and patient-centred pathways for diagnostic and treatment approaches are urgently required.

RESUMO

OBJECTIVE: Our objective was to describe the characteristics of patients admitted, discharged and readmitted, due to COVID-19, to a central London acute-care hospital during the second peak, in particular in relation to corticosteroids use. METHODS: We reviewed patients admitted from the community to University College Hospital (UCH) with COVID-19 as their primary diagnosis between 1st-31st December 2020. Re-attendance and readmission data were collected for patients who re-presented within 10 days following discharge. Data were retrospectively collected. RESULTS: 196 patients were admitted from the community with a diagnosis of COVID-19 and discharged alive in December 2020. Corticosteroids were prescribed in hospital for a median of 5 days (IQR 3-8). 20 patients (10.2%) were readmitted within 10 days. 11/20 received corticosteroids in the first admission of which 10 had received 1-3 days of corticosteroids. Readmission rate in those receiving 1-3 days of corticosteroids was 25%. CONCLUSIONS: Most international guidelines have recommended providing up to 10 days of corticosteroids for severe COVID-19 but stopping on discharge. Our findings show shorter courses of corticosteroids during admission are associated with an increased risk of being readmitted and support continuing the course of corticosteroids after hospital discharge monitored in the virtual ward setting.

RESUMO

Pressure on acute medical services in the pandemic mandated an assertive emergency department (ED) discharge policy. Given the potential for subsequent deterioration and growing appreciation of complications relating to COVID-19 infection, this follow up study was instigated to provide clinical reassurance that discharged patients had followed a safe clinical course. 199 patients discharged from the ED of our central London hospital were identified over a 20-day period at the height of the pandemic in April 2020. 44 had already reattended ED and 12 had been admitted. At 2-week telephone follow-up, 14 patients were identified who required urgent recall for assessment. At 4-week telephone follow-up, 87 patients were identified with persistent symptoms requiring face to face review. A COVID-19 follow-up clinic was therefore established to provide multi-professional review and diagnostics. 65 patients attended for this assessment. This is the first report on outcomes in COVID-19 infected patients discharged from an ED. It highlights the importance of safety-netting after discharge, the difficulty in predicting which patients might deteriorate and the need for appropriate follow up services.

RESUMO

The COVID-19 pandemic has necessitated rapid adaptation of healthcare providers to new clinical and logistical challenges. Following identification of high levels of emergency department (ED) reattendance among patients with suspected COVID-19 at our centre, we piloted a rapid remote follow-up service for this patient group. We present our service framework and evaluation of our pilot cohort of 192 patients. We followed up patients by telephone within 36 hours of their ED attendance. Pulse oximetry was used for remote monitoring of a subset of patients. Patients required between one and six consecutive telephone assessments, dependent on illness severity, and 23 patients were recalled for in-person assessment. Approximately half of patients with confirmed or probable COVID-19 required onward referral for respiratory follow-up. This framework reduced unplanned ED reattendances in comparison with a retrospective comparator cohort (4.7% from 22.6%). We reproduced these findings in a validation cohort with a high prevalence of acute COVID-19, managed through the clinic in September-October 2020, where we identified an unplanned ED reattendance rate of 5.2%. We propose that rapid remote follow-up is a mechanism by which ambulatory patients can be clinically supported during the acute phase of illness, with benefits both to patient care and to health service resilience.

RESUMO

OBJECTIVES: To describe a cohort of self-isolating healthcare workers (HCWs) with presumed COVID-19. DESIGN: A cross-sectional, single-centre study. SETTING: A large, teaching hospital based in Central London with tertiary infection services. PARTICIPANTS: 236 HCWs completed a survey distributed by internal staff email bulletin. 167 were women and 65 men. MEASURES: Information on symptomatology, exposures and health-seeking behaviour were collected from participants by self-report. RESULTS: The 236 respondents reported illness compatible with COVID-19 and there was an increase in illness reporting during March 2020 Diagnostic swabs were not routinely performed. Cough (n=179, 75.8%), fever (n=138, 58.5%), breathlessness (n=84, 35.6%) were reported. Anosmia was reported in 42.2%. Fever generally settled within 1 week (n=110/138, 88%). Several respondents remained at home and did not seek formal medical attention despite reporting severe breathlessness and measuring hypoxia (n=5/9, 55.6%). 2 patients required hospital admission but recovered following oxygen therapy. 84 respondents (41.2%) required greater than the obligated 7 days off work and 9 required greater than 3 weeks off. CONCLUSION: There was a significant increase in staff reporting illness compatible with possible COVID-19 during March 2020. Subsequent serology studies at the same hospital study site have confirmed sero-positivity for COVID-19 up to 45% by the end of April 2020 in frontline HCWs. The study revealed a concerning lack of healthcare seeking in respondents with significant red flag symptoms (severe breathlessness, hypoxia). This study also highlighted anosmia as a key symptom of COVID-19 early in the pandemic, prior to this symptom being more widely recognised as a feature of COVID-19.

RESUMO

Maternal alcohol exposure during pregnancy can substantially impact the development of the fetus, causing a range of symptoms, known as fetal alcohol spectrum disorders (FASDs), such as cognitive dysfunction and psychiatric disorders, with the pathophysiology and mechanisms largely unknown. Recently developed human cerebral organoids from induced pluripotent stem cells are similar to fetal brains in the aspects of development and structure. These models allow more relevant in vitro systems to be developed for studying FASDs than animal models. Modeling binge drinking using human cerebral organoids, we sought to quantify the downstream toxic effects of alcohol (ethanol) on neural pathology phenotypes and signaling pathways within the organoids. The results revealed that alcohol exposure resulted in unhealthy organoids at cellular, subcellular, bioenergetic metabolism, and gene expression levels. Alcohol induced apoptosis on organoids. The apoptotic effects of alcohol on the organoids depended on the alcohol concentration and varied between cell types. Specifically, neurons were more vulnerable to alcohol-induced apoptosis than astrocytes. The alcohol-treated organoids exhibit ultrastructural changes such as disruption of mitochondria cristae, decreased intensity of mitochondrial matrix, and disorganized cytoskeleton. Alcohol exposure also resulted in mitochondrial dysfunction and metabolic stress in the organoids as evidenced by (1) decreased mitochondrial oxygen consumption rates being linked to basal respiration, ATP production, proton leak, maximal respiration and spare respiratory capacity, and (2) increase of non-mitochondrial respiration in alcohol-treated organoids compared with control groups. Furthermore, we found that alcohol treatment affected the expression of 199 genes out of 17,195 genes analyzed. Bioinformatic analyses showed the association of these dysregulated genes with 37 pathways related to clinically relevant pathologies such as psychiatric disorders, behavior, nervous system development and function, organismal injury and abnormalities, and cellular development. Notably, 187 of these genes are critically involved in neurodevelopment, and/or implicated in nervous system physiology and neurodegeneration. Furthermore, the identified genes are key regulators of multiple pathways linked in networks. This study extends for the first time animal models of binge drinking-related FASDs to a human model, allowing in-depth analyses of neurotoxicity at tissue, cellular, subcellular, metabolism, and gene levels. Hereby, we provide novel insights into alcohol-induced pathologic phenotypes, cell type-specific vulnerability, and affected signaling pathways and molecular networks, that can contribute to a better understanding of the developmental neurotoxic effects of binge drinking during pregnancy.

RESUMO

OBJECTIVES: CTD and systemic vasculitis impact on health-related quality of life. Treatment can be complex, involving multiple medical specialities. The aim of this study was to investigate psychological and self-management support for patients in secondary care. METHODS: An online survey of health professionals in the UK, including 45 multiple-choice and free-text questions, was analysed descriptively. Free-text survey responses were analysed thematically to identify health professionals' perceptions of best practice and unmet needs. RESULTS: The online survey included 120 health professionals (34% specialist nurses, 51% doctors and 12% allied health professionals), predominantly working in rheumatology (52.9%) and nephrology (21.5%) departments. Access to self-management programmes or clinics for people with CTD or vasculitis was available in 23% of rheumatology and 8% of nephrology departments. In response to 'How well is your team providing self-management support to people with CTD or vasculitis?', 38% of respondents reported 'not very well' or 'not well at all'. Direct access to psychological support was available in 76.9% of nephrology and 32.8% of rheumatology departments. More than 80% of respondents would like additional training. Key themes from the qualitative data (free-text survey responses) included the importance of: dedicated psychological support and self-management programmes for people with CTD and vasculitis, a whole-team approach (specialist teams empowering people to manage their own care), staff training (e.g. brief psychological interventions) and signposting to resources, including patient charities. CONCLUSION: People with CTD and vasculitis have complex needs, and improvements in self-management and psychological support are required in UK rheumatology and nephrology departments.
