    The 70 kDa and 90 kDa heat shock proteins Hsp70 and Hsp90 are two abundant and highly conserved ATP-dependent molecular chaperones that participate in the maintenance of cellular homeostasis. In Escherichia coli, Hsp90 (Hsp90Ec) and Hsp70 (DnaK) directly interact and collaborate in protein remodeling. Previous work has produced a model of the direct interaction of both chaperones. The locations of the residues involved have been confirmed and the model has been validated. In this study, we investigate the allosteric communication between Hsp90Ec and DnaK and how the chaperones couple their conformational cycles. Using elastic network models (ENM), normal mode analysis (NMA), and a structural perturbation method (SPM) of asymmetric and symmetric DnaK-Hsp90Ec, we extract biologically relevant vibrations and identify residues involved in allosteric signaling. When one DnaK is bound, the dominant normal modes favor biological motions that orient a substrate protein bound to DnaK within ...

    Reliance on government-led policies have heightened during the COVID-19 pandemic. Further research on the policies associated with outcomes other than mortality rates remains warranted. We aimed to determine associations between government public health policies on the severity of the COVID-19 pandemic. This ecological study including countries reporting ≥25 daily COVID-related deaths until end May 2020, utilised public data on policy indicators described by the Blavatnik school of Government. Associations between policy indicators and severity of the pandemic (mean mortality rate, time to peak, peak deaths per 100,000, cumulative deaths after peak per 100,000 and ratio of mean slope of the descending curve to mean slope of the ascending curve) were measured using Spearman rank-order tests. Analyses were stratified for age, income and region. Among 22 countries, containment policies such as school closures appeared effective in younger populations (rs = −0.620, p = 0.042) and debt/c...

    BackgroundThe COVID-19 pandemic has placed significant pressure on health and social care. Survivors of COVID-19 may be left with substantial functional deficits requiring ongoing care. We aimed to determine whether pre-admission frailty was associated with increased care needs at discharge for patients admitted to hospital with COVID-19.MethodsPatients were included if aged over 18 years old and admitted to hospital with COVID-19 between 27 February and 10 June 2020. The Clinical Frailty Scale (CFS) was used to assess pre-admission frailty status. Admission and discharge care levels were recorded. Data were analysed using a mixed-effects logistic regression adjusted for age, sex, smoking status, comorbidities, and admission CRP as a marker of severity of disease.ResultsThirteen hospitals included patients: 1671 patients were screened, and 840 were excluded including, 521 patients who died before discharge (31.1%). Of the 831 patients who were discharged, the median age was 71 years...

    Patient Reported Outcome Measures (PROMs) assess clinical outcomes from the perspective of the patient. The stroke community recommended fifteen questions for use in stroke survivors, based on the established PROMIS10 with five additional stroke-specific questions. This study aimed to determine its association with the National Institute of Health Stroke Scale (NIHSS) on admission. PROM responses were taken from an existing randomised control trial and, using secondary analysis, the total score was calculated out of 100. The association between PROMs and NIHSS was estimated. Using a multivariable regression, an adjusted mean difference (aMD) in PROM total score for the baseline clinical characteristics was calculated. 343 participants (16.3%) completed the PROM; mean age 71.7 (30–94) years; 133 women (38.8%). There was a strong association between increasing NIHSS Scores on admission to hospital and worsening PROM scores at 6 months (p = 0.002). There was consistency between the NIH...

    Frailty assessed using Clinical Frailty Scale (CFS) is a good predictor of adverse clinical events including mortality in older people. CFS is also an essential criterion for determining ceilings of care in people with COVID-19. Our aims were to assess the prevalence of frailty in older patients hospitalised with COVID-19, their sex and age distribution, and the completion rate of the CFS tool in evaluating frailty. Methods: Data were collected from thirteen sites. CFS was assessed routinely at the time of admission to hospital and ranged from 1 (very fit) to 9 (terminally ill). The completion rate of the CFS was assessed. The presence of major comorbidities such as diabetes and cardiovascular disease was noted. Results: A total of 1277 older patients with COVID-19, aged ≥ 65 (79.9 ± 8.1) years were included in the study, with 98.5% having fully completed CFS. The total prevalence of frailty (CFS ≥ 5) was 66.9%, being higher in women than men (75.2% vs. 59.4%, p < 0.001). Frailty...

    Background: In a large UK study we investigated the relationship between smartphone addiction and sleep quality in a young adult population.Methods: We undertook a large UK cross-sectional observational study of 1,043 participants aged 18 to 30 between January 21st and February 30th 2019. Participants completed the Smartphone Addiction Scale Short Version, an adapted Pittsburgh Sleep Quality Score Index and reported smartphone use reduction strategies using both in-person (n = 968) and online (n = 75) questionnaires. A crude and adjusted logistic regression was fitted to assess risk factors for smartphone addiction, and the association between smartphone addiction and poor sleep.Results: One thousand seventy one questionnaires were returned, of which 1,043 participants were included, with median age 21.1 [interquartile range (IQR) 19–22]. Seven hundred and sixty three (73.2%) were female, and 406 reported smartphone addiction (38.9%). A large proportion of participants disclosed poo...

    Coronavirus disease 2019 (COVID-19) infection causes acute lung injury, resulting from aggressive inflammation initiated by viral replication. There has been much speculation about the potential role of non-steroidal inflammatory drugs (NSAIDs), which increase the expression of angiotensin-converting enzyme 2 (ACE2), a binding target for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to enter the host cell, which could lead to poorer outcomes in COVID-19 disease. The aim of this study was to examine the association between routine use of NSAIDs and outcomes in hospitalised patients with COVID-19. This was a multicentre, observational study, with data collected from adult patients with COVID-19 admitted to eight UK hospitals. Of 1222 patients eligible to be included, 54 (4.4%) were routinely prescribed NSAIDs prior to admission. Univariate results suggested a modest protective effect from the use of NSAIDs, but in the multivariable analysis, there was no association bet...

    Background Over the past decade, smartphone use has become widespread amongst today’s children and young people (CYP) which parallels increases in poor mental health in this group. Simultaneously, media concern abounds about the existence of ‘smartphone addiction’ or problematic smartphone use. There has been much recent research concerning the prevalence of problematic smartphone use is in children and young people who use smartphones, and how this syndrome relates to mental health outcomes, but this has not been synthesized and critically evaluated. Aims To conduct a systematic review and meta-analysis to examine the prevalence of PSU and quantify the association with mental health harms. Methods A search strategy using Medical Subject Headings was developed and adapted for eight databases between January 1, 1st 2011 to October 15th 2017. No language restriction was applied. Of 924 studies identified, 41 were included in this review, three of which were cohort studies and 38 were ...

    Cancer survival rates in the UK are lower in comparison with similar countries in Europe and this may be linked to socioeconomic inequalities in stage of cancer diagnosis and survival. Targeted cancer awareness interventions have the potential to improve earlier symptomatic diagnosis and reduce socioeconomic inequalities in cancer outcomes. The health check is an innovative, theory-based intervention designed to increase awareness of cancer symptoms and risk factors, and encourage timely help seeking among adults living in deprived communities. A prospective, non-randomised evaluation was undertaken to test the feasibility and acceptability of the health check for adults aged 40 years and over living in deprived areas of Wales. Primary outcomes included recruitment and retention of approximately 100 adults, reach to participants in the lowest deprivation quartile, and intervention acceptability. Secondary outcomes included self-reported cancer symptom recognition, help-seeking behav...

    to investigate the prevalence and impact of frailty for general surgical patients. we conducted a systematic review and meta-analysis. Studies published between 1 January 1980 and 31 August 2017 were searched from seven databases. Incidence of clinical outcomes (mortality at Days 30 and 90; readmission at Day 30, surgical complications and length of stay) were estimated by frailty subgroup (not-frail, pre-frail and frail). 2,281 participants from nine observational studies were included, 49.3% (1013/2055) were males. Mean age ranged from 61 to 77 years old. Eight studies provided outcome data and were quality assessed and of fair or good quality, and one study only provided an estimate of prevalence and was not quality assessed. The prevalence estimate ranged between 31.3 and 45.8% for pre-frailty, and 10.4 and 37.0% for frailty. After pooling, Day 30 mortality was 8% (95% CI: 4-12%; I2 = 0%) for frail compared to 1% for non-frail patients (95% CI: 0-2%; I2 = 75%). Due to heterogene...

    Treatment options for severe, enduring anorexia nervosa (SE-AN) are limited. Non-invasive neuromodulation is a promising emerging intervention. Our study is a feasibility randomised controlled trial of repetitive transcranial magnetic stimulation (rTMS) in individuals with SE-AN, which aims to inform the design of a future large-scale trial. Double-blind, parallel group, two-arm, sham-controlled trial. Specialist eating disorders centre. Community-dwelling people with anorexia nervosa, an illness duration of ≥3 years and at least one previous completed treatment. Participants received 20 sessions (administered over 4 weeks) of MRI-guided real or sham high-frequency rTMS to the left dorsolateral prefrontal cortex in addition to treatment-as-usual. Primary outcomes were recruitment, attendance and retention rates. Secondary outcomes included body mass index (BMI), eating disorder symptoms, mood, quality of life and rTMS safety and tolerability. Assessments were conducted at baseline, ...

    UK-wide national clinical guidelines promote routine 6-month post-stroke follow-up assessment. However, as part of this 6-month assessment little information is gathered from the patient's perspective. The means of collecting this patient-centred information might be served best by a patient-reported outcome measure (PROM) at the 6-month assessment time point. Currently, four different methods of 6-month follow-up assessment occur; the most common being face-to-face interview followed by telephone interview, postal questionnaire and online questionnaire. Therefore, this study will investigate if the acceptability of telephone, online or postal administration of a PROM at the 6-month post-stoke time point is not inferior to face-to-face administration. A UK multicentre, blinded (analyst and researcher), pragmatic, non-inferiority study, with 80% power using a 2.5% non-inferiority margin was designed to compare the acceptability of three modes of administration (telephone intervie...

    The impact of flooding on mental health is exacerbated due to secondary stressors, although the mechanism of action is not understood. We investigated the role of secondary stressors on psychological outcomes through analysis of data collected one-year after flooding, and effect modification by sex. We analysed data from the English National Study on Flooding and Health collected from households flooded, disrupted and unexposed to flooding during 2013-14. Psychological outcomes were probable depression, anxiety and post-traumatic stress disorder (PTSD). Parsimonious multivariable logistic regression models were fitted to determine the effect of secondary stressors on the psychological outcomes. Sex was tested as an effect modifier using subgroup analyses. A total of 2006 people participated (55.5% women, mean age 60 years old). Participants reporting concerns about their personal health and that of their family (concerns about health) had greater odds of probable depression (adjuste...

    International guideline recommendations for the use of folate and its derivatives in the treatment of unipolar depressive disorders are confused and contradictory, perhaps reflecting wide variations in the underpinning evidence base. We discuss differing methods of evidence synthesis in the formulation of international guideline recommendations. As an example we evaluated the efficacy of folate and its derivatives in unipolar depression via systematic review and meta-analysis. We searched Medline, EMBASE, PsychInfo and CENTRAL from database inception until 1 May 2017 for randomised controlled trials. We included trials that evaluated folate or its derivatives as monotherapy or to augment antidepressant therapy compared with placebo in patients with unipolar depressive illness. Standardised mean differences were used and studies were introduced as subgroups to explain the heterogeneity. Quality was assessed using the Grading of Recommendations Assessment, Development and Evaluation. ...

    The determinants of cognitive impairment and delirium during acute illness are poorly understood, despite being common among older people. Anemia is common in older people, and there is ongoing debate regarding the association between anemia, cognitive impairment and delirium, primarily in non-surgical patients. Using data from the Older Persons Surgical Outcomes Collaboration 2013 and 2014 audit cycles, we examined the association between anemia and cognitive outcomes in patients aged ≥65 years admitted to five UK acute surgical units. On admission, the Confusion Assessment Method was carried out to detect delirium. Cognition was assessed using the Montreal Cognitive Assessment, and two levels of impairment were defined as Montreal Cognitive Assessment <26 and <20. Logistic regression models were constructed to examine these associations in all participants, and individuals aged ≥75 years only. A total of 653 patients, with a median age of 76.5 years (interquartile range 73.0...

    Smoking cessation was examined among a subset of current smokers who were high-risk participants in the UK Lung Cancer Screening (UKLS) pilot trial of low-dose CT screening. High-risk individuals aged 50-75 years who completed baseline questionnaires were randomised to CT screening (intervention) or usual care (no screening control). Smoking habit was determined at baseline using self-report. Smokers were asked whether they had quit smoking since joining UKLS at short-term follow-up (2 weeks after baseline scan results or control assignment) and longer-term follow-up (up to 2 years after recruitment). Intention to treat (ITT) regression analyses were undertaken, adjusting for baseline lung cancer distress, trial site and sociodemographic variables. Of a total of 4055 individuals randomised to CT screening or control, 1546 were baseline smokers (787 control, 759 intervention). Smoking cessation rates were 5% (control n=36/786) versus 10% (intervention n=75/758) at 2 weeks and 10% (co...

    The UK performs poorly relative to other economically developed countries on numerous indicators of care quality for children. The contribution of iatrogenic harm to these outcomes is unclear. As primary care is the first point of healthcare contact for most children, we sought to investigate the safety of care provided to children in this setting. We undertook a mixed methods investigation of reports of primary care patient safety incidents involving sick children from England and Wales' National Reporting and Learning System between 1 January 2005 and 1 December 2013. Two reviewers independently selected relevant incident reports meeting prespecified criteria, and then descriptively analyzed these reports to identify the most frequent and harmful incident types. This was followed by an in-depth thematic analysis of a purposive sample of reports to understand the reasons underpinning incidents. Key candidate areas for strengthening primary care provision and reducing the risks ...

    The UK Lung Cancer Screening (UKLS) trial is a randomised pilot trial of low-dose CT (LDCT) screening for individuals at high risk of lung cancer. We assessed the long-term psychosocial impact on individuals participating in the UKLS trial. A random sample of individuals aged 50-75 years was contacted via primary care. High-risk individuals who completed T0 questionnaires (baseline) were randomised to LDCT screening (intervention) or usual care (no screening control). T1 questionnaires were sent 2 weeks after baseline scan results or control assignment. T2 questionnaires were sent up to 2 years after recruitment. Measures included cancer distress, anxiety, depression and decision satisfaction. A total of 4037 high-risk individuals were randomised and they completed T0 questionnaires (n=2018 intervention, n=2019 control). Cancer distress was higher at T1 in intervention arm participants who received positive screening results (p≤0.001), but not at T2 (p=0.04). T2 anxiety (p≤0.001) an...

    Influenza is a significant cause of morbidity and excess mortality, yet vaccine coverage in the UK remains below target. Community pharmacies are increasingly being promoted as an alternative to vaccination by GPs. To explore and verify the factors that influence the relative performance of pharmacies providing NHS influenza vaccinations. A mixed methods study utilising qualitative, semi-structured interviews and quantitative analysis of predictors of vaccination numbers in community pharmacies in Wales. Interviews were conducted with 16 pharmacists who participated in the Welsh national pharmacy influenza service in 2013-2014. A purposive sampling strategy was used. Qualitative findings were analysed using framework analysis. Potential predictors of vaccination numbers were identified from interviews and a literature review, and included in a multivariable regression model. The contribution of community pharmacies towards vaccination in Wales is small. Findings suggest that communi...

    Multimorbidity is the presence of 2 or more medical conditions. This increasingly used assessment has not been assessed in a surgical population. The objectives of this study were to assess the prevalence of multimorbidity and its association with common outcome measures. A cross-sectional observational study. A UK-based multicentre study, included participants between July and October 2014. Consecutive emergency (non-elective) general surgical patients admitted to hospital, aged over 65 years. The outcome measures were (1) the prevalence of multimorbidity and (2) the association between multimorbidity and frailty; the rate and severity of surgery; length of hospital stay; readmission to hospital within 30 days of discharge; and death at 30 and 90 days. Data were collected on 413 participants aged 65-98 years (median 77 years, (IQR (70-84)). 51.6% (212/413) participants were women. Multimorbidity was present in 74% (95% CI 69.7% to 78.2%) of the population and increased with age (p&...

    Discharge from hospital presents significant risks to patient safety, with up to one in five patients experiencing adverse events within 3 weeks of leaving hospital. To describe the frequency and types of patient safety incidents associated with discharge from secondary to primary care, and commonly described contributory factors to identify recommendations for practice. A mixed methods analysis of 598 patient safety incident reports in England and Wales related to 'Discharge' from the National Reporting and Learning System. Detailed data coding (with 20% double-coding), data summaries generated using descriptive statistical analysis, and thematic analysis of special-case sample of reports. Incident type, contributory factors, type, and level of harm were described, informing recommendations for future practice. A total of 598 eligible reports were analysed. The four main themes were: errors in discharge communication (n = 151; 54% causing harm); errors in referrals to commu...

    To determine the proportion of children aged <2 years who have been asphyxiated presenting with epistaxis in the absence of trauma or medical explanation and to identify the characteristics of the clinical presentation indicative of asphyxiation. An all-language systematic review was conducted by searching 10 databases from 1900 to 2015 and gray literature to identify high-quality studies that included children with epistaxis aged <2 years (alive or dead) with explicit confirmation of intentional or unintentional asphyxiation (upper airway obstruction). Studies of traumatic or pathological epistaxis were excluded. For each comparative study, the proportion of children presenting with epistaxis that were asphyxiated is reported with 95% CI. Of 2706 studies identified, 100 underwent full review, resulting in 6 included studies representing 30 children with asphyxiation-related epistaxis and 74 children with non-asphyxiation-related epistaxis. The proportion of children presentin...

    Objectives: To assess the effectiveness and applicability of endodontic irrigants in general dental practice Methods: We conducted a Cochrane systematic review which described the effectiveness and we now plan to extend the work using the conceptual framework of generalizability to primary care ( Nasser et al Fam Pract 2012; 29 Suppl 1). To implement this model in validating studies, we used the pragmatic-explanatory continuum (PRECIS tool) to evaluate each of the included trials. Effectiveness was evaluated based on a comprehensive systematic search for randomized controlled trials in several databases (13 Sep 2011). No language restrictions were applied. Appraisal was undertaken by two people using the risk of bias tool and PRECIS tool. Results: Eleven trials involving 851 participants with 879 teeth were included. Most of the trials were low powered and rated unclear risk of bias. Four trials compared sodium hypochlorite versus chlorhexidine, however no primary outcomes and only ...

    ABSTRACT Aim Healthcare failures have been identified in 26% of UK child deaths. Despite children accounting for 40% of general practitioners’ workload, little is known about the safety of care in the community setting. Using data from a national reporting system, this study aimed to characterise the paediatric safety incidents occurring in general practice to inform a logic model with identified priorities for clinical practice improvement.

    Background Providing good cancer support is an essential aspect of treating patients holistically. Patient experience is greatly affected by the support they receive. There is limited information about the access to cancer support and cancer care patients receive on a national level. The National Cancer Experience Survey Programme 2010 investigated current cancer care across 158 NHS Trusts in England. The survey is one of the largest undertaken involving cancer patients in the world, with a large sample size and high response rate (67%). Method We undertook secondary analysis of data from 63,144 patients. We classified 80 different cancer types into 12 groups. We examined four different domains of cancer supportive care. These were: ‘clinical nurse specialist (CNS) support' (knowing name of CNS, access to CNS and communication with CNS); support from GP after discharge; ‘Support information' (being informed about support groups, free prescriptions, and financial support); an...

    The current study aimed to identify the barriers to participation among high-risk individuals in the UK Lung Cancer Screening (UKLS) pilot trial. The UKLS pilot trial is a randomised controlled trial of low-dose CT (LDCT) screening that has recruited high-risk people using a population approach in the Cambridge and Liverpool areas. High-risk individuals aged 50-75 years were invited to participate in UKLS. Individuals were excluded if a LDCT scan was performed within the last year, if they were unable to provide consent, or if LDCT screening was unable to be carried out due to coexisting comorbidities. Statistical associations between individual characteristics and UKLS uptake were examined using multivariable regression modelling. In those who completed a non-participation questionnaire (NPQ), thematic analysis of free-text data was undertaken to identify reasons for not taking part, with subsequent exploratory linkage of key themes to risk factors for non-uptake. Comparative data ...

    Children are scheduled to receive 18-20 immunizations before their 18th birthday in England and Wales; this approximates to 13 million vaccines administered per annum. Each immunization represents a potential opportunity for immunization-related error and effective immunization is imperative to maintain the public health benefit from immunization. Using data from a national reporting system, this study aimed to characterize pediatric immunization-related safety incident reports from primary care in England and Wales between 2002 and 2013. A cross-sectional mixed methods study was undertaken. This comprised reading the free-text of the incident report and applying codes to describe incident type, potential contributory factors, harm severity, and incident outcomes. A subsequent thematic analysis was undertaken to interpret the most commonly occurring codes, such as those describing the incident, events leading up to it and reported contributory factors, within the contexts they were ...

    the risk factors for and frequency of antibiotic prescription and antibiotic-associated diarrhoea (AAD) among care home residents are unknown. to prospectively study frequency and risks for antibiotic prescribing and AAD for care home residents. a 12-month prospective cohort study in care homes across South Wales. antibiotic prescriptions and the development of AAD were recorded on case report forms. We defined AAD as three or more loose stools in a 24-h period occurring within 8 weeks of exposure to an antibiotic. we recruited 279 residents from 10 care homes. The incidence of antibiotic prescriptions was 2.16 prescriptions per resident year (95% CI: 1.90-2.46). Antibiotics were less likely to be prescribed to residents from dual-registered homes (OR compared with nursing homes: 0.38, 95% CI: 0.18-0.79). For those who were prescribed antibiotics, the incidence of AAD was 0.57 episodes per resident year (95% CI: 0.41-0.81 episodes). AAD was more likely in residents who were prescrib...

    ABSTRACT Aims Whilst epistaxis is a frequent and trivial finding in most children, it is rare in those aged less than 2 years. Epistaxis has been observed amongst intentionally asphyxiated infants using covert surveillance, although the precise relationship between epistaxis and asphyxia has subsequently been called into question. This systematic review aims to determine the probability of asphyxia amongst young children presenting with epistaxis, and define the clinical characteristics of such children.

    In the United Kingdom, 26% of child deaths have identifiable failures in care. Although children account for 40% of family physicians' workload, little is known about the safety of care in the community setting. Using data from a national patient safety incident reporting system, this study aimed to characterize the pediatric safety incidents occurring in family practice. We undertook a retrospective, cross-sectional, mixed methods study of pediatric reports submitted to the UK National Reporting and Learning System from family practice. Analysis involved detailed data coding using multiaxial frameworks, descriptive statistical analysis, and thematic analysis of a special-case sample of reports. Using frequency distributions and cross-tabulations, the relationships between incident types and contributory factors were explored. Of 1788 reports identified, 763 (42.7%) described harm to children. Three crosscutting priority areas were identified: medication management, assessment a...
