      Bah, Ebrima; Michelangeli, Frank (Oxford University Press (OUP), 2020-05-29)
      Abstract Objectives To find out the overlapping and correlating relationships between serum haptoglobin level, haptoglobin genotype and phenotype, blood haemoglobin level and zinc protoporphyrin (measured in washed RBCs) in association to prevalence of anaemia. It will focus on comparing all the mention components in contrast to each other. The study will also look for the frequency distribution of the major HP alleles. Methods 1278 participants were randomly selected. Blood samples collected by trained nurses. Data generation was done at the Medical research council (keneba field station) research site. Data Analysis was conducted at the university of Chester with the assistance of the computer department team. Results P = 0.000 indicating anaemia prevalence with HP 1 allele. P > 0.05 when ID, IDA and AI relates with HP genotype. Positive correlation between ZnPP and HP serum level, but negative between ZnPP and Hb. P = 0.000 between ZnPP and IDA. P = 0.024 between HP genotype and Hb level. P = 0.013 between HP genotype and HP serum. P = 0.100 between HP genotype and ZnPP. P = 0.000 between ZnPP and IDA. P = 0.024 between HP genotype and Hb. ZnPP shared a positive correlation with HP serum level, and a negative correlation with Hb level. The correlation significant = 0.01 level (2-tailed) P = 0.01. The correlation between HP genotype and HP serum level was significant with P = 0.013, but the correlation between HP genotype and ZnPP was not significant with P = 0.100. Conclusions HP genotype had association with anaemia prevalence and more occurrence was observed in carriers of the type ‘1’ allele. It had no association with ID, IDA and AI. HP genotype had association with HP serum level and Hb level but had no association with ZnPP level. ZnPP level was observed to have had association with HP serum level, Hb level and IDA; but had no association with ID and AI in the region. Funding Sources All the resources used in this study were from MRC Keneba (International Nutrition Group) which is supported by funds from the UK Medical Research Council (MRC) and the UK Department for International Development (DFID) under the MRC/DFID Concordat agreement (Hennig et al., 2015).
    • Neferine induces autophagy-dependent cell death in apoptosis-resistant cancers via ryanodine receptor and Ca

      Law, Betty Yuen Kwan; Michelangeli, Francesco; Qu, Yuan Qing; orcid: 0000-0003-3733-3661; Xu, Su-Wei; Han, Yu; Mok, Simon Wing Fai; Dias, Ivo Ricardo De Seabra Rodrigues; Javed, Masood-Ul-Hassan; Chan, Wai-Kit; Xue, Wei-Wei; et al. (2019-12-27)
      Resistance of cancer cells to chemotherapy is a significant clinical concern and mechanisms regulating cell death in cancer therapy, including apoptosis, autophagy or necrosis, have been extensively investigated over the last decade. Accordingly, the identification of medicinal compounds against chemoresistant cancer cells via new mechanism of action is highly desired. Autophagy is important in inducing cell death or survival in cancer therapy. Recently, novel autophagy activators isolated from natural products were shown to induce autophagic cell death in apoptosis-resistant cancer cells in a calcium-dependent manner. Therefore, enhancement of autophagy may serve as additional therapeutic strategy against these resistant cancers. By computational docking analysis, biochemical assays, and advanced live-cell imaging, we identified that neferine, a natural alkaloid from Nelumbo nucifera, induces autophagy by activating the ryanodine receptor and calcium release. With well-known apoptotic agents, such as staurosporine, taxol, doxorubicin, cisplatin and etoposide, utilized as controls, neferine was shown to induce autophagic cell death in a panel of cancer cells, including apoptosis-defective and -resistant cancer cells or isogenic cancer cells, via calcium mobilization through the activation of ryanodine receptor and Ulk-1-PERK and AMPK-mTOR signaling cascades. Taken together, this study provides insights into the cytotoxic mechanism of neferine-induced autophagy through ryanodine receptor activation in resistant cancers.

    • Quantifying the impact of tissue metabolism on solute transport in feto-placental microvascular networks

      Nye, Gareth; Erlich, Alexander; Brownbill, Paul; Chernyavsky, Igor; Jenson, Oliver; University of Manchester (Royal Society, 2019-08-16)
      The primary exchange units in the human placenta are terminal villi, in which fetal capillary networks are surrounded by a thin layer of villous tissue, separating fetal from maternal blood. To understand how the complex spatial structure of villi influences their function, we use an image-based theoretical model to study the effect of tissue metabolism on the transport of solutes from maternal blood into the fetal circulation. For solute that is taken up under first-order kinetics, we show that the transition between flow-limited and diffusion-limited transport depends on two new dimensionless parameters defined in terms of key geometric quantities, with strong solute uptake promoting flow-limited transport conditions. We present a simple algebraic approximation for solute uptake rate as a function of flow conditions, metabolic rate and villous geometry. For oxygen, accounting for nonlinear kinetics using physiological parameter values, our model predicts that villous metabolism does not significantly impact oxygen transfer to fetal blood, although the partitioning of fluxes between the villous tissue and the capillary network depends strongly on the flow regime
    • Cancerous inhibitor of protein phosphatase 2A (CIP2A) modifies energy metabolism via 5′ AMP-activated protein kinase signalling in malignant cells

      Austin, James A.; orcid: 0000-0002-5384-5221; Jenkins, Rosalind E.; Austin, Gemma M.; Glenn, Mark A.; Dunn, Karen; Scott, Laura; Lucas, Claire M.; Clark, Richard E. (Portland Press Ltd., 2019-08-15)
      Abstract Cancerous inhibitor of protein phosphatase 2A (CIP2A) is an adverse biomarker across many malignancies. Using K562 cells engineered to have high or low CIP2A expression, we show that high CIP2A levels significantly bias cellular energy production towards oxidative phosphorylation (OXPHOS) rather than glycolysis. Mass spectrometric analysis of CIP2A interactors and isobaric tagging for relative and absolute protein quantitation (ITRAQ) experiments identified many associated proteins, several of which co-vary with CIP2A level. Many of these CIP2A associating and co-varying proteins are involved in energy metabolism including OXPHOS, or in 5′ AMP-activated protein kinase (AMPK) signalling, and manipulating AMPK activity mimics the effects of low/high CIP2A on OXPHOS. These effects are dependent on the availability of nutrients, driven by metabolic changes caused by CIP2A. CIP2A level did not affect starvation-induced AMPK phosphorylation of Unc-51 autophagy activating kinase 1 (ULK-1) at Ser555, but autophagy activity correlated with an increase in AMPK activity, to suggest that some AMPK processes are uncoupled by CIP2A, likely via its inhibition of protein phosphatase 2A (PP2A). The data demonstrate that AMPK mediates this novel CIP2A effect on energy generation in malignant cells.

    • A preliminary cohort study assessing routine blood analyte levels and neurological outcome following spinal cord injury.

      Brown, Sharon J.; Bernardo Harrington,; Hulme, Charlotte; Morris, Rachel; Bennett, Anna; Tsang, Wai-Hung; Osman, Aheed; Chowdhury, Joy; Kumar, Naveen; Wright, Karina T. (2019-07-16)
      There is increasing interest in the identification of biomarkers that could predict neurological outcome following a spinal cord injury (SCI). Although initial American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade is a good indicator of neurological outcome, for the patient and clinicians, an element of uncertainty remains. This preliminary study aimed to assess the additive potential of routine blood analytes following Principal Component Analysis (PCA) to develop prognostic models for neurological outcome following spinal cord injury. Routine blood and clinical data were collected from SCI patients (n=82) and PCA used to reduce the number of blood analytes into related factors. Outcome neurology was obtained from AIS scores at 3- and 12-months post-injury, with Motor (AIS and Total including all myotomes) and Sensory (AIS, Touch and Pain) being assessed individually. Multiple regression models were created for all outcome measures. Blood analytes relating to 'liver function' and 'acute inflammation and liver function' factors were found to significantly increase prediction of neurological outcome at both 3 months (Touch, Pain and AIS Sensory) and at 1 year (Pain, R2 increased by 0.025 and Total Motor, R2 increased by 0.016). For some models 'liver function' and 'acute inflammation and liver function' factors were both significantly predictive with the greatest combined R2 improvement of 0.043 occurring for 3m Pain prediction. These preliminary findings support ongoing research into the use of routine blood analytes in the prediction of neurological outcome in SCI patients.
    • A pilot randomised controlled trial of a programme of psychosocial interventions (Resettle) for high risk personality disordered offenders

      Nathan, Rajan; Centifanti, Luna; Baker, Vikki; Hill, Jonathan (Elsevier, 2019-07-08)
      Abstract Background Offenders with personality disorder experience significant co-morbid mental health problems and present with an increased risk of offending. The evidence for the effectiveness of interventions for personality disordered offenders in the community is limited. This study was a pilot study to determine the feasibility of a randomised controlled trial (RCT) of an intervention known as Resettle for personality disordered offenders and to explore the possible effects of this intervention. Methods Potential participants were recruited from referrals of male prisoners to Resettle. Those consenting underwent baseline assessments before being randomised to Resettle or treatment as usual. Officially recorded and self-report offending was assessed over two years following release from custody. Of the 110 eligible participants, 72 (65%) participated in the study of whom 38 were randomised to Resettle and 34 to treatment as usual. The two groups had a similar psychiatric and offending profile. Results Analysis of officially recorded offences at two years found mixed results, but whether adopting an intent-to-treat approach or including only those who received the intervention there was no clear evidence of an effect of the intervention. A comparison of self-report offending found no effect of Resettle in an intent-to-treat analysis, but there was an effect when the analysis involved only those participating in the intervention. Conclusions This study demonstrated that with some adjustments it was possible to carry out an RCT of a complex intervention for personality disordered offenders in a criminal justice setting. Some, but not conclusive, evidence was found in favour of the intervention.
    • Promoting patient utilization of outpatient cardiac rehabilitation: A joint International Council and Canadian Association of Cardiovascular Prevention and Rehabilitation position statement

      Santiago de Araújo Pio, Carolina; Varnfield, Marlien; Sarrafzadegan, Nizal; Beckie, Theresa M.; Babu, Abraham S.; Baidya, Sumana; Buckley, John P.; Chen, Ssu-Yuan; Gagliardi, Anna; Heine, Martin; et al. (Elsevier, 2019-07-04)
      Background: Cardiac Rehabilitation (CR) is a recommendation in international clinical practice guidelines given its’ benefits, however use is suboptimal. The purpose of this position statement was to translate evidence on interventions that increase CR enrolment and adherence into implementable recommendations. Methods: The writing panel was constituted by representatives of societies internationally concerned with preventive cardiology, and included disciplines that would be implementing the recommendations. Patient partners served, as well as policy-makers. The statement was developed in accordance with AGREE II, among other guideline checklists. Recommendations were based on our update of the Cochrane review on interventions to promote patient utilization of CR. These were circulated to panel members, who were asked to rate each on a 7-point Likert scale in terms of scientific acceptability, actionability, and feasibility of assessment. A web call was convened to achieve consensus and confirm strength of the recommendations (based on GRADE). The draft underwent external review and public comment. Results: The 3 drafted recommendations were that to increase enrolment, healthcare providers, particularly nurses (strong), should promote CR to patients face-to-face (strong), and that to increase adherence part of CR could be delivered remotely (weak). Ratings for the 3 recommendations were 5.95±0.69 (mean ± standard deviation), 5.33±1.12 and 5.64±1.08, respectively. Conclusions: Interventions can significantly increase utilization of CR, and hence should be widely applied. We call upon cardiac care institutions to implement these strategies to augment CR utilization, and to ensure CR programs are adequately resourced to serve enrolling patients and support them to complete programs.
    • Office workers’ experiences of attempts to reduce sitting-time: An exploratory, mixed- methods uncontrolled intervention pilot study

      Dewitt, Stephen; Hall, Jennifer; Smith, Lee; Buckley, John P.; Biddle, Stuart J. H.; Mansfield, Louise; Gardner, Benjamin; University of Chester (BMC Springer Nature, 2019-06-25)
      Background: Office workers typically sit for most of the workday, which has been linked to physical and mental ill- health and premature death. This mixed-methods study sought to identify barriers and facilitators to reducing sitting and increasing standing among office workers who received an intervention prototype (the ‘ReSiT [Reducing Sitting Time] Study’). The intervention comprised a sit-stand workstation and tailored advice to enhance motivation, capability and opportunity to displace sitting with standing. Methods: Twenty-nine UK university office workers (aged ≥18y, working ≥3 days per week, most time spent at a seated desk) participated in a 13-week uncontrolled study. They were initially monitored for one-week. In a subsequent face-to-face consultation, participants received sitting time feedback from a prior one-week monitoring period, and selected from a set of tailored sitting-reduction techniques. Quantitative data comprising sitting, standing and stepping time, which were objectively monitored for 7 consecutive days across three post- intervention timepoints, were descriptively analysed. Qualitative data, from semi-structured interviews conducted at 1, 6 and 12-weeks post-intervention, were thematically analysed. Results: Compared to baseline, mean sitting time decreased at weeks 1, 6 and 12 by 49.7mins, 118.2mins, and 109.7mins respectively. Despite prior concerns about colleagues’ reactions to standing, many reported encouragement from others, and standing could be equally conducive to social interaction or creating private, personal space. Some perceived less cognitively-demanding tasks to be more conducive to standing, though some found standing offered a valued break from challenging tasks. Participants prioritised workload over sitting reduction and were more likely to stand after rather than during work task completion. Temporary context changes, such as holidays, threatened to derail newfound routines. Conclusions: Our findings emphasise the importance of understanding workers’ mental representations of their work, and the social functions of sitting and standing in the workplace. Workplace intervention developers should incorporate a pre-intervention sitting time monitoring period, encourage workers to identify personally meaningful tasks and cues for standing, and build organisational support for sitting-reduction. We will use these insights to refine our intervention for self-administered delivery. Trial registration: ISRCTN29395780 (registered 21 November 2016).

    • Palliative opioid use, palliative sedation and euthanasia: reaffirming the distinction.

      Schofield, Guy; Baker, Idris; Bullock, Rachel; Clare, Hannah; Clark, Paul; Willis, Derek; Gannon, Craig; George, Rob (2019-06-20)
      We read with interest the extended essay published from Riisfeldt and are encouraged by an empirical ethics article which attempts to ground theory and its claims in the real world. However, such attempts also have real-world consequences. We are concerned to read the paper's conclusion that clinical evidence weakens the distinction between euthanasia and normal palliative care prescribing. This is important. Globally, the most significant barrier to adequate symptom control in people with life-limiting illness is poor access to opioid analgesia. Opiophobia makes clinicians reluctant to prescribe and their patients reluctant to take opioids that might provide significant improvements in quality of life. We argue that the evidence base for the safety of opioid prescribing is broader than that presented, restricting the search to palliative care literature produces significant bias as safety experience and literature for opioids and sedatives exists in many fields. This is not acknowledged in the synthesis presented. By considering additional evidence, we reject the need for agnosticism and reaffirm that palliative opioid prescribing is safe. Second, palliative sedation in a clinical context is a poorly defined concept covering multiple interventions and treatment intentions. We detail these and show that continuous deep palliative sedation (CDPS) is a specific practice that remains controversial globally and is not considered routine practice. Rejecting agnosticism towards opioids and excluding CDPS from the definition of routine care allows the rejection of Riisfeldt's headline conclusion. On these grounds, we reaffirm the important distinction between palliative care prescribing and euthanasia in practice. [Abstract copyright: © Author(s) (or their employer(s)) 2019.

      Celastrol exhibits anti-arthritic effect in rheumatoid arthritis (RA), but the role of celastrol-mediated Ca mobilization in treatment of RA remains unelucidated. Here, we illustrate the regulatory role of celastrol-induced Ca signalling in synovial fibroblasts of RA patients and adjuvant-induced arthritis (AIA) in rats. Molecular target of celastrol was determined by computational docking, Ca dynamic and functional assays on SERCA. Ca -mediated autophagy in RASFs/RAFLS and the underlying mechanism were verified by quantification of endogenous LC3-II puncta, immunoblotting, and flow cytometry with the Ca chelator (BAPTA/AM) or suitable inhibitors. The anti-arthritic effect of celastrol, autophagy induction and growth rate of synovial fibroblasts in AIA rats were monitored by microCT and immunofluorescence staining. mRNA from joint tissues of AIA rats was isolated for transcriptional analysis of inflammatory genes. The role of Ca in regulating the identified genes was investigated by knockdown of calmodulin, calpains, and calcineurin. Celastrol inhibited SERCA to induce autophagy-dependent cytotoxicity in RASFs/RAFLS via CaMKKβ-AMPK-mTOR pathway and repressed arthritis symptoms in AIA rats. BAPTA/AM hampered the in vitro and in vivo effectiveness of celastrol. Inflammatory- and autoimmunity-associated genes downregulated by celastrol in joint tissues of AIA rat were restored by BAPTA/AM. Knockdown of calmodulin, calpains, and calcineurin in RAFLS confirmed the role of Ca in celastrol-regulated gene expression. Celastrol triggered Ca signalling to induce autophagic cell death in RASFs/RAFLS and ameliorated arthritis in AIA rats mediated by calcium-dependent/-binding proteins facilitating the exploitation of anti-arthritic drugs based on manipulation of Ca signalling.

    • The importance of clinician, patient and researcher collaborations in Alport syndrome

      Rheault, Michelle N.; Savige, Judith; Randles, Michael J.; Weinstock, André; Stepney, Melissa; Turner, Neil; Parziale, Gina; Gross, Oliver; Flinter, Frances A; Miner, Jeffrey H; et al. (Springer Nature, 2019-05-01)
      Alport syndrome (AS) is caused by mutations in the genes COL4A3, COL4A4 or COL4A5 and is characterised by progressive glomerular disease, sensorineural hearing loss and ocular defects. Occurring in less than 1:5000, AS is rare genetic disorder but still accounts for >1% of the prevalent population receiving renal replacement therapy. There is also increasing awareness about the risk of chronic kidney disease in individuals with heterozygous mutations in AS genes. The mainstay of current therapy is the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers, yet potential new therapies are now entering clinical trials. The 2017 International Workshop on Alport Syndrome in Glasgow was a preconference workshop ahead of the 50th anniversary meeting of the European Society for Pediatric Nephrology. It focussed on updates in clinical practice, genetics, basic science and also incorporated patient perspectives. More than 80 international experts including clinicians, geneticists, researchers from academia and industry, and patient representatives took part in panel discussions and breakout groups. This report summarises the workshop proceedings and the relevant contemporary literature. It highlights the unique clinician, patient and researcher collaborations achieved by regular engagement between the groups.

    • The Differences in Acute Management of Asthma in Adults and Children

      Chavasse, Richard; Scott, Stephen (Frontiers Media S.A., 2019-03-11)
      Acute asthma or wheeze is a common presentation to emergency services for both adults and children. Although there are phenotypic differences between asthma syndromes, the management of acute symptoms follow similar lines. This article looks at the similarities and differences in approaches for children and adults. Some of these may be age dependent, such as the physiological parameters used to define the severity of the attack or the use of age appropriate inhaler devices. Other differences may reflect the availability of evidence. In other areas there is conflicting evidence between adult and pediatric studies such as a temporary increase in dose of inhaled corticosteroids during an acute attack. Overall there are more similarities than differences.
    • CD271-selected mesenchymal stem cells from adipose tissue enhance cartilage repair and are less angiogenic than plastic adherent mesenchymal stem cells

      Kohli, Nupur; Johnson, William Eustace Basil; Uchida, Kenzo; Aston University, University of Chester, University of Fukui (Nature, 2019-02-28)
      CD271 is a marker of bone marrow MSCs with enhanced differentiation capacity for bone or cartilage repair. However, the nature of CD271+ MSCs from adipose tissue (AT) is less well understood. Here, we investigated the differentiation, wound healing and angiogenic capacity of plastic adherent MSCs (PA MSCs) versus CD271+ MSCs from AT. There was no difference in the extent to which PA MSCs and CD271+ MSCs formed osteoblasts, adipocytes or chondrocytes in vitro. In contrast, CD271+ MSCs transplanted into athymic rats significantly enhanced osteochondral wound healing with reduced vascularisation in the repair tissue compared to PA MSCs and control animals; there was little histological evidence of mature articular cartilage formation in all animals. Conditioned medium from CD271+ MSC cultures was less angiogenic than PA MSC conditioned medium, and had little effect on endothelial cell migration or endothelial tubule formation in vitro. The low angiogenic activity of CD271+ MSCs and improved early stage tissue repair of osteochondral lesions when transplanted, along with a comparable differentiation capacity along mesenchymal lineages when induced, suggests that these selected cells are a better candidate than PA MSCs for the repair of cartilaginous tissue.

    • Tuberculosis notification in a private tertiary care teaching hospital in South India: a mixed-methods study

      Siddaiah, Archana; Ahmed, Mohammad Naseer; Kumar, Ajay M. V.; D’Souza, George; Wilkinson, Ewan; Maung, Thae Maung; Rodrigues, Rashmi (BMJ Publishing Group, 2019-02-05)
      Objectives India contributes approximately 25% of the ‘missing’ cases of tuberculosis (TB) globally. Even though ~50% of patients with TB are diagnosed and treated within India’s private sector, few are notified to the public healthcare system. India’s TB notification policy mandates that all patients with TB are notified through Nikshay (TB notification portal). We undertook this study in a private hospital to assess the proportion notified and factors affecting TB notifications. We explored barriers and probable solutions to TB notification qualitatively from health provider’s perspective. Study setting Private, tertiary care, teaching hospital in Bengaluru, South India. Methodology This was a mixed-methods study. Quantitative component comprised a retrospective review of hospital records between 1 January 2015 and 31 December 2017 to determine TB notifications. The qualitative component comprised key informant interviews and focus groups to elicit the barriers and facilitators of TB notification. Results Of 3820 patients diagnosed and treated, 885 (23.2%) were notified. Notifications of sputum smear-positive patients were significantly more likely, while notifications of children were less likely. Qualitative analysis yielded themes reflecting the barriers to TB notification and their solutions. Themes related to barriers were: (1) basic diagnostic procedures and treatment promote notification; (2) misconceptions regarding notification and its process are common among healthcare providers; (3) despite a national notification system other factors have prevented notification of all patients; and (4) establishing hospital systems for notification will go a long way in improving notifications. Conclusions The proportion of patients with TB notified by the hospital was low. A comprehensive approach both by the hospital management and the national TB programme is necessary for improving notification. This includes improving awareness among healthcare providers about the requirement for TB notifications, establishing a single notification portal in hospital, digitally linking hospital records to Nikshay and designating one person to be responsible for notification.
    • Standards and core components for cardiovascular disease prevention and rehabilitation; BACPR

      Cowie, Aynsley; Buckley, John P.; Doherty, Patrick; Furze, Gill; Hayward, Jo; Jones, Jennifer; Speck, Linda; Dalal, Hayes; Mills, Joseph; University Centre Shrewsbury (BMJ, 2019-01-30)
      In 2017, the British Association for Cardiovascular Prevention and Rehabilitation published its official document detailing standards and core components for cardiovascular prevention and rehabilitation. Building on the success of previous editions of this document (published in 2007 and 2012), the 2017 update aims to further emphasise to commissioners, clinicians, politicians and the public the importance of robust, quality indicators of cardiac rehabilitation (CR) service delivery. Otherwise, its overall aim remains consistent with the previous publications—to provide a precedent on which all effective cardiovascular prevention and rehabilitation programmes are based and a framework for use in assessment of variation in service delivery quality. In this 2017 edition, the previously described seven standards and core components have both been revised to six, with a greater focus on measurable clinical outcomes, audit and certification. The principles within the updated document underpin the six-stage pathway of care for CR, and reflect the extensive evidence base now available within the field. To help improve current services, close collaboration between commissioners and CR providers is advocated, with use of the CR costing tool in financial planning of programmes. The document specifies how quality assurance can be facilitated through local audit, and advocates routine upload of individual-level data to the annual British Heart Foundation National Audit of Cardiac Rehabilitation, and application for national certification ensuring attainment of a minimum quality standard. Although developed for the UK, these standards and core components may be applicable to other countries.
