Abstract
Chronic pain is a common comorbidity in people with HIV (PWH), with prevalence estimates of 25-85%. Research in this area is growing, but significant gaps remain. A Global Task Force of HIV experts was organized to brainstorm a scientific agenda and identify measurement domains critical to advancing research in this field. Experts were identified through literature searches and snowball sampling. Two online questionnaires were developed by Task Force members. Questionnaire 1 asked participants to identify knowledge gaps in the field of HIV and chronic pain and identify measurement domains in studies of chronic pain in PWH. Responses were ranked in order of importance in Questionnaire 2, which was followed by a group discussion. 29 experts completed Questionnaire 1, 25 completed Questionnaire 2, and 21 participated in the group. Many important clinical and research priorities emerged, including the need to examine etiologies of chronic pain in PWH. Pain-related measurement domains were discussed, with a primary focus on domains that could be assessed in a standardized manner across various cohorts that include PWH in different countries. We collaboratively identified clinical and research priorities, as well as gaps in standardization of measurement domains, that can be used to move the field forward.

Prevalence of early postpartum depression and associated risk factors among selected women in southern Malawi: a nested observational study. BMC Pregnancy Childbirth 2023; 23:229. [PMID: 37020182 PMCID: PMC10074867 DOI: 10.1186/s12884-023-05501-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 03/06/2023] [Indexed: 04/07/2023] Open
Abstract
BACKGROUND The birth of a child should be a time of celebration. However, for many women, childbirth represents a time of great vulnerability to becoming mentally unwell, a neglected maternal morbidity. This study aimed to determine the prevalence of early postpartum depression (PPD) and its associated risk factors among women giving birth at health facilities in southern Malawi. Identifying women vulnerable to PPD will help clinicians provide appropriately targeted interventions before discharge from the maternity ward. METHOD We conducted a nested cross-sectional study. Women were screened for early PPD using a locally validated Edinburgh Postpartum Depression Scale (EPDS) as they were discharged from the maternity ward. The prevalence of moderate or severe (EPDS ≥ 6) and severe (EPDS ≥ 9) PPD was determined, including 95% confidence intervals (CI). Data on maternal age, education and marital status, income source, religion, gravidity, and HIV status, among others, were collected during the second trimester of pregnancy, and obstetric and infant characteristics during childbirth were examined as potential risk factors for early PPD using univariable and multivariable logistic regression analyses. RESULTS Data contributed by 636 women were analysed. Of these women, 9.6% (95% CI; 7.4-12.1%) had moderate to severe early PPD using an EPDS cut-off of ≥ 6, and 3.3% (95% CI; 2.1-5.0%) had severe early PPD using an EPDS cut-off of ≥ 9. Multivariable analyses indicated that maternal anaemia at birth (aOR; 2.65, CI; 1.49-4.71, p-value; 0.001) was associated with increased risk for moderate and/or severe early PPD, while live birth outcome (aOR; 0.15, 95% CI; 0.04-0.54, p-value; 0.004), being single compared to divorced/widowed (aOR; 0.09, 95% CI; 0.02-0.55, p-value; 0.009), and lower education level (aOR; 0.36, 95% CI; 0.20-0.65, p-value; 0.001) were associated with decreased risk. Being HIV positive (aOR; 2.88, 95% CI; 1.08-7.67, p-value; 0.035) was associated with severe PPD only. CONCLUSION The prevalence of early PPD was slightly lower in our selected sample compared to previous reports in Malawi and was associated with maternal anaemia at birth, non-live birth, being divorced/widowed and HIV-positive status. Therefore, health workers should screen for depressive symptoms in women who are at increased risk as they are discharged from the maternity ward for early identification and treatment.

Abstract
BACKGROUND Palliative care services seek to improve the wellbeing of family carers of people living with serious and life-limiting illness. To help achieve this goal, systematic reviews have recommended priority areas for family carer research and the need to improve the quality of study design. Policy makers have also advocated for enhanced family carer support. However, there are specific methodological considerations and challenges in designing and conducting carer research conducted during the course of the serious illness trajectory and in bereavement. AIM To develop strategies to improve the design and conduct of research with family carers. DESIGN Expert elicitation study using an adapted version of the 'Identify, Discuss, Estimate and Aggregate' elicitation protocol, supplemented with strategies from peer-reviewed literature. SETTING/PARTICIPANTS Nine members of the management committee of the European Association for Palliative Care's Reference group on family carer research, comprising international senior research academics in family caregiving. RESULTS A compilation of recommended strategies and checklist was created to: (a) help researchers plan research involving family carers focussing on: preparation, conduct and dissemination and (b) assist ethics committees and funding bodies to evaluate proposals. CONCLUSIONS The strategies and checklist for conducting research with family carers may enhance methodologically rigorous research. Consequently, researchers, practitioners and policy makers will not only gain a more comprehensive understanding of the unmet needs of family carers but also promote the development of empirically sound interventions.

Abstract
Patients diagnosed with tuberculosis (TB) continue to experience clinical uncertainty and high mortality and to bear a high burden of symptoms and other concerns. Additional concerns may be family support needs and stigma, particularly the latter, as TB and human immunodeficiency virus (HIV) coinfection are common. Human rights covenants, global health policy and the End TB Strategy all recommend palliative care as an essential component of care services. As established in the resolution adopted by the World Health Assembly (WHA) on "Strengthening of palliative care as a component of comprehensive care throughout the life course", there is a "need for palliative care across disease groups (non-communicable diseases, and infectious diseases, including HIV and multidrug-resistant tuberculosis), and across all age groups". We address the ethical imperative to respect the dignity and fundamental rights of people with TB by providing palliative care. We review the evidence for the need for person-centred palliative care and highlight novel models that utilise the skills and training functions of specialist palliative care to achieve better care. We outline simple recommendations for the delivery of specialist and generalist palliative care, offer suggestions on how to ensure optimal coverage by enabling access to appropriate good-quality palliative care at all points of the health system, including alongside treatment. Finally, we set out the current priorities for research and policy to ensure that quality care is delivered to all who need it irrespective of treatment outcome, to minimise distress and to optimise engagement in treatment and care.

Abstract
Pain is a highly prevalent and burdensome symptom among people with HIV (PWH). This study aims to identify how the experience of living with HIV and chronic pain influences pain beliefs, health-seeking and pain management. Thirty-nine purposively sampled PWH with chronic pain (sample characteristics = 61% women, 79% Black, Asian and minority ethnic groups, 18% men who have sex with men, 45-54 median age category) participated in focus groups in London. Focus groups were co-facilitated with community members. Transcripts wereanalysed using a thematic approach. Findings revealed that HIV stigma, fractured care pathways, and general practitioners' lack of HIV training are barriers to supported pain management. Unaddressed pain results in poorer mental health and reduced quality of life, which has important clinical implications for HIV treatment adherence. Creating HIV-specific pain resources, activating social networks, and pain self-management techniques are potential solutions. Person-centred assessment and HIV training is needed to help clinicians identify PWH with chronic pain. Clear guidelines need to be developed to identify which health service providers are responsible for chronic pain management in PWH. This study generated a refined version of the Fear Avoidance Model that introduces a dimension of HIV-specific behaviours that impact PWHs seeking chronic pain management.

Abstract
UNAIDS advocates person-centred care (PCC) for people living with HIV/AIDS (PLWHA) to improve outcomes and wellbeing. We appraised the evidence of person-centred models of community HIV care delivered or led by trained healthcare professionals and its impact on care outcomes. A systematic review was conducted in line with PRISMA guidance. Six electronic databases (CINAHL, Embase, PubMed, Medline, PsycINFO and Web of Science) were searched from January 1980 to April 2019. We included primary studies of any design of PCC models; for adults aged ≥15 years; that were delivered or led by trained HCP. Data were extracted including study location, design, quality, outcomes measured and effectiveness. Five out of 1393 studies met the inclusion criteria, of which four were from a high-income country and one a lower-middle income country. Of the PCC components (physical, psychological, social and spiritual wellbeing) delivered alongside HIV clinical management, one study delivered 2, two studies delivered 3 and two studies delivered all 4 components. This review highlights the lack of outcome evidence for person-centred HIV care, and of concurrent focus on all domains of concern for PLWHA within interventions. Clear articulation of the meaning, practice of PCC and implementation strategies are needed to meet policy recommendations.

Abstract
PURPOSE COVID-19 patients requiring mechanical ventilation can overwhelm existing bed capacity. We aimed to better understand the factors that influence the trajectory of tracheostomy care in this population to facilitate capacity planning and improve outcomes. METHODS We conducted an observational cohort study of patients in a high-volume centre in the worst-affected region of the UK including all patients that underwent tracheostomy for COVID-19 pneumonitis ventilatory wean from 1st March 2020 to 10th May 2020. The primary outcome was time from insertion to decannulation. The analysis utilised Cox regression to account for patients that are still progressing through their tracheostomy pathway. RESULTS At the point of analysis, a median 21 days (IQR 15-28) post-tracheostomy and 39 days (IQR 32-45) post-intubation, 35/69 (57.4%) patients had been decannulated a median of 17 days (IQR 12-20.5) post-insertion. The overall median age was 55 (IQR 48-61) with a male-to-female ratio of 2:1. In Cox regression analysis, FiO2 at tracheostomy ≥ 0.4 (HR 1.80; 95% CI 0.89-3.60; p = 0.048) and last pre-tracheostomy peak cough flow (HR 2.27; 95% CI 1.78-4.45; p = 0.001) were independent variables associated with prolonged time to decannulation. CONCLUSION Higher FiO2 at tracheostomy and higher pre-tracheostomy peak cough flow are associated with increased delay in COVID-19 tracheostomy patient decannulation. These finding comprise the most comprehensive report of COVID-19 tracheostomy decannulation to date and will assist service planning for future peaks of this pandemic.

Abstract
BACKGROUND People living with HIV experience burdensome multidimensional symptoms and concerns requiring person-centred care. Routine use of patient reported outcome measures can improve outcomes. There is no brief patient reported outcome measure (PROM) that currently reflects the breadth of concerns for people living with HIV. This study aimed to develop and cognitively test a brief novel patient reported outcome measure for use within routine adult HIV care- the "Positive Outcomes" HIV PROM. METHODS Development followed the COSMIN taxonomy and guidance for relevance and comprehensiveness, and Rothrock guidance on development of valid patient reported outcome measures. The Positive Outcomes HIV PROM was developed by a steering group (people living with HIV, HIV professionals and health services researchers) using findings from a previously reported qualitative study of priority outcomes for people living with HIV. The prototype measure was cognitively tested with a purposive sample of people living with HIV. RESULTS The Positive Outcomes HIV PROM consists of 23 questions (22 structured, and one open question) informed by the priorities of key stakeholders (n = 28 people living with HIV, n = 21 HIV professionals and n = 8 HIV commissioners) to ensure face and content validity, and refined through cognitive testing (n = 6 people living with HIV). Cognitive testing demonstrated high levels of acceptability and accessibility. CONCLUSIONS The Positive Outcomes HIV PROM is the first brief patient reported outcome measure reflecting the diverse needs of people living with HIV designed specifically for use in the clinical setting to support patient assessment and care, and drive service quality improvement. It is derived from primary data on the priority outcomes for people living with HIV and is comprehensive and acceptable. Further psychometric testing is required to ensure reliability and responsiveness.

Abstract
Background Advances in peri-operative care of surgical oncology patients result in shorter hospital stays. Earlier discharge may bring benefits, but complications can occur while patients are recovering at home. Electronic patient-reported outcome (ePRO) systems may enhance remote, real-time symptom monitoring and detection of complications after hospital discharge, thereby improving patient safety and outcomes. Evidence of the effectiveness of ePRO systems in surgical oncology is lacking. This pilot study evaluated the feasibility of a real-time electronic symptom monitoring system for patients after discharge following cancer-related upper gastrointestinal surgery. Methods A pilot study in two UK hospitals included patients who had undergone cancer-related upper gastrointestinal surgery. Participants completed the ePRO symptom-report at discharge, twice in the first week and weekly post-discharge. Symptom-report completeness, system actions, barriers to using the ePRO system and technical performance were examined. The ePRO surgery system is an online symptom-report that allows clinicians to view patient symptom-reports within hospital electronic health records and was developed as part of the eRAPID project. Clinically derived algorithms provide patients with tailored self-management advice, prompts to contact a clinician or automated clinician alerts depending on symptom severity. Interviews with participants and clinicians determined the acceptability of the ePRO system to support patients and their clinical management during recovery. Results Ninety-one patients were approached, of which 40 consented to participate (27 male, mean age 64 years). Symptom-report response rates were high (range 63–100%). Of 197 ePRO completions analysed, 76 (39%) triggered self-management advice, 72 (36%) trigged advice to contact a clinician, 9 (5%) triggered a clinician alert and 40 (20%) did not require advice. Participants found the ePRO system reassuring, providing timely information and advice relevant to supporting their recovery. Clinicians regarded the system as a useful adjunct to usual care, by signposting patients to seek appropriate help and enhancing their understanding of patients’ experiences during recovery. Conclusion Use of the ePRO system for the real-time, remote monitoring of symptoms in patients recovering from cancer-related upper gastrointestinal surgery is feasible and acceptable. A definitive randomised controlled trial is needed to evaluate the impact of the system on patients’ wellbeing after hospital discharge.

Abstract
OBJECTIVES Since 2013, the London HIV Mortality Review Group has conducted annual reviews of deaths among people with HIV to reduce avoidable mortality. METHODS All London HIV care Trusts reported data on 2016 patient deaths in 2017. Deaths were submitted using a modified Causes of Death in HIV reporting form and categorized by a specialist HIV pathologist and two HIV clinicians. RESULTS There were 206 deaths reported; 77% were among men. Median age at death was 56 years. Cause was established for 82% of deaths, with non-AIDS-related malignancies and AIDS-defining illnesses being the most common causes reported. Risk factors in the year before death included: tobacco smoking (37%), excessive alcohol consumption (19%), non-injecting drug use (10%), injecting drug use (7%) and opioid substitution therapy (6%). Thirty-nine per cent of patients had a history of depression, 33% chronic hypertension, 27% dyslipidaemia, 17% coinfection with hepatitis B virus and/or hepatitis C virus and 14% diabetes mellitus. At the time of death, 81% of patients were on antiretroviral therapy (ART), 61% had a CD4 count < 350 cells/μL, and 24% had a viral load ≥ 200 HIV-1 RNA copies/mL. Thirty-six per cent of deaths were unexpected; 61% of expected deaths were in hospital. Two-thirds of expected deaths had a prior end-of-life care discussion documented. CONCLUSIONS In 2016, most deaths were attributable to non-AIDS-related conditions and the majority of patients were on ART and virally suppressed. However, several potentially preventable deaths were identified and underlying risk factors were common. As London HIV patients are not representative of people with HIV in the UK, a national mortality review is warranted.

Abstract
OBJECTIVES People living with HIV (PLWH) have multidimensional concerns requiring person-centred care. Routine use of patient-reported outcome measures (PROMs) improves outcomes. No brief PROM currently reflects the breadth of concerns for PLWH. This study sought to identify priority outcomes for PLWH, model current practice, explore views on introducing PROMs into routine care, and devise a model for person-centred care incorporating the PROM. METHODS A cross-national multi-centre study (London, Brighton and Dublin) was carried out. Semi-structured qualitative interviews with adult PLWH, HIV health care professionals and HIV commissioners (responsible for planning and commissioning services) were performed. Interviews were analysed using thematic and framework analysis. RESULTS PLWH (n = 28), professionals (n = 21) and commissioners (n = 8) described concerns related to living with HIV across six domains: physical (e.g. pain and gastrointestinal symptoms), cognitive (e.g. memory and sleep), psychological (e.g. anxiety and depression), social (e.g. isolation and intimacy), welfare (e.g. finances and fears regarding change of immigration status), and information (e.g. long-term outcomes) needs. Themes were highly inter-related, impacting across domains of need (e.g. physical and cognitive problems impacting on psychological and social wellbeing). Perceived benefits of using PROMs in routine HIV care included improved person-centredness, patient empowerment, fewer missed concerns, increased engagement with services, and informed planning of services. Potential challenges included heterogeneity of PLWH, literacy, and utility for those who struggle to engage with care. CONCLUSIONS This study presents a novel model of person-centred care incorporating an HIV-specific PROM. The model reflects priorities of key stakeholders. Explicit use of PROMs in routine HIV care could afford benefits for PLWH, clinical teams and commissioners.

Abstract
Background and context: The home healthcare market in Jordan is nascent with little service offered. It suffers from a highly fragmented and underregulated landscape. The limited access to qualified trustworthy home care services, lack of professional home care training, and lack of home health care insurance coverage have added to the heavy in-patient bed demand and delayed hospital discharges especially for disabled or terminally ill patients. Aim: To establish a comprehensive national home care program to improve the delivery of palliative and home care services in Jordan, and to conduct a situational analysis and generate policy recommendations. Strategy/Tactics: We used multiple strategies to reach our objectives. 1. Expansion of home care services at King Hussein Cancer Center (KHCC) to create a local demonstration project. 2. Building health care professional capacity by offering variety of educational programs. 3. Improving quality of service delivery by generating clinical practice guidelines, such as standards operating procedures and patient and family educational materials. 4. Use the pilot operational and financial data to generate an economic model to inform the development of similar home health care units in hospitals across Jordan. 5. National advocacy and building effective partnership with all related stakeholders to advance national policy. Program/Policy process: Between May 2016 and May 2017, 7818 home care visits were conducted by KHCC. For capacity building; 678 health care professionals were trained in palliative and home care, out of which 366 participants were females (54%). Palliative care was successfully recognized as a specialty by the Jordan Nursing Council and recognized as a subspecialty by the Jordan Medical Council. The palliative and home care standards of practice were included in the health care accreditation council. The analysis of economic evaluation data suggested that home care services decreased in-patient utilization and costs which is advantageous to a country with limited resources. As a result of the advocacy stream and a collaborative network, the national palliative and home care strategic framework was generated, and endorsed by the Ministry of Health. Outcomes: The NHCI resulted in a very successful pilot project and achieved specialty and subspecialty recognition. Furthermore, we were able to build the capacity of health care professionals and policy makers in the palliative and home care sector from public, private and academic institutions. In the advocacy and policy dimension, the Minister of Health officially approved and adapted the palliative and home care strategic framework that was developed by this initiative. What was learned: Cross-sector collaboration and effective partnership resulted in system change and policy advancement. Developing effective economic systems is essential in low resourced countries. The initiative was supported by a joint grant from the USAID and KHCC.

Abstract
BACKGROUND Cutaneous T-cell lymphomas (CTCL) are rare cancers, which can be difficult to diagnose, are incurable and adversely affect quality of life, particularly in advanced disease. Families often provide care, but little is known about their experiences or needs while caring for their relative with advanced disease or in bereavement. OBJECTIVES To explore the experiences of bereaved family caregivers of patients with CTCL. METHODS Single, semi-structured qualitative interviews were conducted with bereaved family caregivers of patients with CTCL recruited via a supra-regional CTCL clinic. Transcribed interviews were analysed thematically, focusing on advanced disease, the approach of death and bereavement. RESULTS Fifteen carers of 11 deceased patients participated. Experiences clustered under four themes: (1) complexity of care and medical intervention; (2) caregiver roles in advanced CTCL; (3) person-centred vs. organization-centred care in advanced CTCL and (4) knowing and not knowing: reflections on dying, death and bereavement. Caregivers often had vivid recollections of the challenges of caring for their relative with advanced CTCL and some took on quasi-professional roles as a result. Advanced disease made high demands on both organizational flexibility and family resources. For many caregivers, seeing disease progression was a prolonged and profoundly traumatic experience. The extent to which they were prepared for their relative's death and supported in bereavement was highly variable. Sub-themes within each theme provide more detail about caregiver experiences. CONCLUSIONS Family caregivers should be considered part of the wider healthcare team, acknowledging their multiple roles and the challenges they encounter in looking after their relative with CTCL as the disease progresses. Their experiences highlight the importance of organizational flexibility and of good communication between healthcare providers in advanced CTCL.

Abstract
Geometries of Early Pleistocene [2.58 to 0.78 million years (Ma) ago] ice sheets in northwest Europe are poorly constrained but are required to improve our understanding of past ocean-atmosphere-cryosphere coupling. Ice sheets are believed to have changed in their response to orbital forcing, becoming, from about 1.2 Ma ago, volumetrically larger and longer-lived. We present a multiproxy data set for the North Sea, extending to over a kilometer below the present-day seafloor, which demonstrates spatially extensive glaciation of the basin from the earliest Pleistocene. Ice sheets repeatedly entered the North Sea, south of 60°N, in water depths of up to ~250 m from 2.53 Ma ago and subsequently grounded in the center of the basin, in deeper water, from 1.87 Ma ago. Despite lower global ice volumes, these ice sheets were near comparable in spatial extent to those of the Middle and Late Pleistocene but possibly thinner and moving over slippery (low basal resistance) beds.

Structural and functional analysis of the DOT1L-AF10 complex reveals mechanistic insights into MLL-AF10-associated leukemogenesis. Genes Dev 2018; 32:341-346.

Abstract
The mixed-lineage leukemia (MLL)-AF10 fusion oncoprotein recruits DOT1L to the homeobox A (HOXA) gene cluster through its octapeptide motif leucine zipper (OM-LZ), thereby inducing and maintaining the MLL-AF10-associated leukemogenesis. However, the recognition mechanism between DOT1L and MLL-AF10 is unclear. Here, we present the crystal structures of both apo AF10OM-LZ and its complex with the coiled-coil domain of DOT1L. Disruption of the DOT1L-AF10 interface abrogates MLL-AF10-associated leukemic transformation. We further show that zinc stabilizes the DOT1L-AF10 complex and may be involved in the regulation of the HOXA gene expression. Our studies may also pave the way for the rational design of therapeutic drugs against MLL-rearranged leukemia.

Abstract
BackgroundRespiratory management of obesity hypoventilation syndrome (OHS) focusses on the control of sleep-disordered breathing rather than the treatment of obesity. Currently, there are no data from randomised trials of weight loss targeted rehabilitation programmes for patients with OHS.InterventionA 3-month multimodal hybrid inpatient–outpatient motivation, exercise and nutrition rehabilitation programme, in addition to non invasive ventilation (NIV), would result in greater per cent weight loss compared with standard care.MethodsA single-centre pilot randomised controlled trial allocated patients to either standard care or standard care plus rehabilitation. Primary outcome was per cent weight loss at 12 months with secondary exploratory outcomes of weight loss, exercise capacity and health-related quality of life (HRQOL) at the end of the rehabilitation programme to assess the intervention effect.ResultsThirty-seven patients (11 male, 59.8±12.7 years) with a body mass index of 51.1±7.7 kg/m2 were randomised. At 12 months, there was no between-group difference in per cent weight loss (mean difference −5.9% (95% CI −14.4% to 2.7%; p=0.17)). At 3 months, there was a greater per cent weight loss (mean difference −5% (95% CI −8.3% to −1.4%; p=0.007)), increased exercise capacity (6 min walk test 60 m (95% CI 29.5 to 214.5) vs 20 m (95% CI 11.5 to 81.3); p=0.036) and HRQL (mean difference SF-36 general health score (10 (95% CI 5 to 21.3) vs 0 (95% CI −5 to 10); p=0.02)) in the rehabilitation group.ConclusionIn patients with OHS, a 3-month comprehensive rehabilitation programme, in addition to NIV, resulted in improved weight loss, exercise capacity and QOL at the end of the rehabilitation period, but these effects were not demonstrated at 12 months, in part, due to the limited retention of patients at 12 months.Trial registration numberPre-results; NCT01483716.

Betamethasone-exposed preterm birth does not impair insulin action in adult sheep. J Endocrinol 2017; 232:175-187.

Abstract
Preterm birth is associated with increased risk of type 2 diabetes (T2D) in adulthood; however, the underlying mechanisms are poorly understood. We therefore investigated the effect of preterm birth at ~0.9 of term after antenatal maternal betamethasone on insulin sensitivity, secretion and key determinants in adulthood, in a clinically relevant animal model. Glucose tolerance and insulin secretion (intravenous glucose tolerance test) and whole-body insulin sensitivity (hyperinsulinaemic euglycaemic clamp) were measured and tissue collected in young adult sheep (14 months old) after epostane-induced preterm (9M, 7F) or term delivery (11M, 6F). Glucose tolerance and disposition, insulin secretion, β-cell mass and insulin sensitivity did not differ between term and preterm sheep. Hepatic PRKAG2 expression was greater in preterm than in term males (P = 0.028), but did not differ between preterm and term females. In skeletal muscle, SLC2A4 (P = 0.019), PRKAA2 (P = 0.021) and PRKAG2 (P = 0.049) expression was greater in preterm than in term overall and in males, while INSR (P = 0.047) and AKT2 (P = 0.043) expression was greater in preterm than in term males only. Hepatic PRKAG2 expression correlated positively with whole-body insulin sensitivity in males only. Thus, preterm birth at 0.9 of term after betamethasone does not impair insulin sensitivity or secretion in adult sheep, and has sex-specific effects on gene expression of the insulin signalling pathway. Hence, the increased risk of T2D in preterm humans may be due to factors that initiate preterm delivery or in early neonatal exposures, rather than preterm birth per se.

The substrate binding domains of human SIAH E3 ubiquitin ligases are now crystal clear. Biochim Biophys Acta Gen Subj 2016; 1861:3095-3105.

Abstract
BACKGROUND Seven in absentia homologs (SIAHs) comprise a family of highly conserved E3 ubiquitin ligases that play an important role in regulating signalling pathways in tumorigenesis, including the DNA damage repair and hypoxia response pathways. SIAH1 and SIAH2 have been found to function as a tumour repressor and a proto-oncogene, respectively, despite the high sequence identity of their substrate binding domains (SBDs). Ubiquitin-specific protease USP19 is a deubiquitinase that forms a complex with SIAHs and counteracts the ligase function. Much effort has been made to find selective inhibitors of the SIAHs E3 ligases. Menadione was reported to inhibit SIAH2 specifically. METHODS We used X-ray crystallography, peptide array, bioinformatic analysis, and biophysical techniques to characterize the structure and interaction of SIAHs with deubiquitinases and literature reported compounds. RESULTS We solved the crystal structures of SIAH1 in complex with a USP19 peptide and of the apo form SIAH2. Phylogenetic analysis revealed the SIAH/USP19 complex is conserved in evolution. We demonstrated that menadione destabilizes both SIAH1 and SIAH2 non-specifically through covalent modification. CONCLUSIONS The SBDs of SIAH E3 ligases are structurally similar with a subtle stability difference. USP19 is the only deubiquitinase that directly binds to SIAHs through the substrate binding pocket. Menadione is not a specific inhibitor for SIAH2. GENERAL SIGNIFICANCE The crystallographic models provide structural insights into the substrate binding of the SIAH family E3 ubiquitin ligases that are critically involved in regulating cancer-related pathways. Our results suggest caution should be taken when using menadione as a specific SIAH2 inhibitor.

Abstract
HIV treatment and management is constantly evolving. This is as a result of more treatment options coming on stream, tolerance changes and progress in treatment management. HIV infection today, in resource-rich countries and in the presence of combination therapies, is experienced as lifelong treatment punctuated by adjustments to antiretroviral therapy (ART) regimens. People who are diagnosed as HIV positive face a number of challenges and changes around the decision to commence treatment, responses to treatment and changes in treatment regimens. This study was set up to examine the experience of switching treatments and the impact of such switches on psychological parameters. The method used was a cross-sectional questionnaire study. A group of 779 HIV-positive clinic attendees at four clinics in London and South East England participated in the study (86% response rate). They provided detail of their treatment switching experiences as well as demographic details, risk and optimism evaluations, quality of life, symptom burden, adherence and disclosure information. The sample ( n=779) comprised 183 (24%) females, 76 (10%) heterosexual males and 497 gay males (66%). Self-reported ethnicity was 67% white, 25% black, 3% Asian and 5% mixed/other ethnicity. One hundred and fifty-five (21%) were ART-naïve and 624 (79%) were ART experienced; 161 (22%) were receiving their first regimen, 135 (18%) had experienced one regimen switch, 196 (26%) had multiple switches and 99 (13.3%) had stopped treatment. Treatment naïve, non-switchers and single switchers generally reported lower symptom burden and higher quality of life. Multiple switchers reported higher physical symptom burden and higher global symptom distress scores. Those who had stopped treatment had significantly lower quality-of-life scores than all other groups. Suicidal ideation was high across the groups and nearly a fifth of all respondents had not disclosed their HIV status to anyone. Reported adherence was suboptimal – 79% of subjects were at least 95% adherent on self-report measures of doses taken over the preceding week. In conclusion, nearly half this clinic sample will have switched treatments. A holistic approach is needed to understand the psychological effects of such switches if lifelong treatment is to be maintained and those on antiretroviral treatment are to attain good quality of life and minimize symptom burden.

Abstract
Ubiquitin-specific proteases (USPs) USP15 and USP4 belong to a subset of USPs featuring an N-terminal tandem domain in USP (DUSP) and ubiquitin-like (UBL) domain. Squamous cell carcinoma antigen recognized by T-cell 3 (SART3), a spliceosome recycling factor, binds to the DUSP-UBL domain of USP15 and USP4, recruiting them to the nucleus from the cytosol to control deubiquitination of histone H2B and spliceosomal proteins, respectively. To provide structural insight, we solved crystal structures of SART3 in the apo-form and in complex with the DUSP-UBL domain of USP15 at 2.0 and 3.0 Å, respectively. Structural analysis reveals SART3 contains 12 half-a-tetratricopeptide (HAT) repeats, organized into two subdomains, HAT-N and HAT-C. SART3 dimerizes through the concave surface of HAT-C, whereas the HAT-C convex surface binds USP15 in a novel bipartite mode. Isothermal titration calorimetry measurements and mutagenesis analysis confirmed key residues of USP15 involved in the interaction and indicated USP15 binds 20-fold stronger than USP4.

Comparative study of linear and curvilinear ultrasound probes to assess quadriceps rectus femoris muscle mass in healthy subjects and in patients with chronic respiratory disease. BMJ Open Respir Res 2016; 3:e000103.

Abstract
Introduction Ultrasound measurements of rectus femoris cross-sectional area (RFCSA) are clinically useful measurements in chronic obstructive pulmonary disease (COPD) and critically ill patients. Technical considerations as to the type of probe used, which affects image resolution, have limited widespread clinical application. We hypothesised that measurement of RFCSA would be similar with linear and curvilinear probes. Methods Four studies were performed to compare the use of the curvilinear probe in measuring RFCSA. Study 1 investigated agreement of RFCSA measurements using linear and curvilinear probes in healthy subjects, and in patients with chronic respiratory disease. Study 2 investigated the intra-rater and inter-rater agreement using the curvilinear probe. Study 3 investigated the agreement of RFCSA measured from whole and spliced images using the linear probe. Study 4 investigated the applicability of ultrasound in measuring RFCSA during the acute and recovery phases of an exacerbation of COPD. Results Study 1 showed demonstrated no difference in the measurement of RFCSA using the curvilinear and linear probes (308±104 mm2 vs 320±117 mm2, p=0.80; intraclass correlation coefficient (ICC)>0.97). Study 2 demonstrated high intra-rater and inter-rater reliability of RFCSA measurement with ICC>0.95 for both. Study 3 showed that the spliced image from the linear probe was similar to the whole image RFCSA (308±103.5 vs 263±147 mm2, p=0.34; ICC>0.98). Study 4 confirmed the clinical acceptability of using the curvilinear probe during an exacerbation of COPD. There were relationships observed between admission RFCSA and body mass index (r=+0.65, p=0.018), and between RFCSA at admission and physical activity levels at 4 weeks post-hospital discharge (r=+0.75, p=0.006). Conclusions These studies have demonstrated that clinicians can employ whole and spliced images from the linear probe or use images from the curvilinear probe, to measure RFCSA. This will extend the clinical applicability of ultrasound in the measurement of muscle mass in all patient groups.

Electrophysiological correlates of self-specific prediction errors in the human brain. Neuroimage 2015; 125:13-24.

Abstract
Recognising one's self, vs. others, is a key component of self-awareness, crucial for social interactions. Here we investigated whether processing self-face and self-body images can be explained by the brain's prediction of sensory events, based on regularities in the given context. We measured evoked cortical responses while participants observed alternating sequences of self-face or other-face images (experiment 1) and self-body or other-body images (experiment 2), which were embedded in an identity-irrelevant task. In experiment 1, the expected sequences were violated by deviant morphed images, which contained 33%, 66% or 100% of the self-face when the other's face was expected (and vice versa). In experiment 2, the anticipated sequences were violated by deviant images of the self when the other's image was expected (and vice versa), or by two deviant images composed of pictures of the self-face attached to the other's body, or the other's face attached to the self-body. This manipulation allowed control of the prediction error associated with the self or the other's image. Deviant self-images (but not deviant images of the other) elicited a visual mismatch response (vMMR)--a cortical index of violations of regularity. This was source localised to face and body related visual, sensorimotor and limbic areas and had amplitude proportional to the amount of deviance from the self-image. We provide novel evidence that self-processing can be described by the brain's prediction error system, which accounts for self-bias in visual processing. These findings are discussed in the light of recent predictive coding models of self-processing.

Out of the shadows: non-communicable diseases and palliative care in Africa. BMJ Support Palliat Care 2015; 7:128-132.

Abstract
Non-communicable diseases (NCDs) in Africa have been comparatively neglected, partly due to donor-driven funding priorities. This is despite NCDs being the principal cause of mortality globally, with the majority incidence occurring in low-income and middle-income nations. Most of the patients with NCDs will suffer from pain, breathlessness and other physical symptoms, or need support with psychosocial or spiritual problems. Reflecting regional disease prevalence, late-stage clinical presentation, limited funding and restricted access to curative therapies, palliative care need in Africa is significantly high. Although palliative care provision has advanced significantly on the continent in the past decade, much of this development was driven by services for adult HIV patients. However, recent international and regional political declarations and commitments constitute a new global NCD agenda that calls for the integration of palliative care into the NCD response. This could be achieved under a chronic care model of service provision in partnership with other clinical providers in an integrated care continuum spanning prevention, early detection, diagnosis, treatment, survivorship and the end of life. Four important challenges have to be addressed if palliative care is to contribute meaningfully to this NCD agenda: (1) existing variation in the ability of countries to deal with NCDs per se; (2) ensuring clinical partners are integrated effectively with palliative care; (3) agreeing implementation is linked to relevant national-level and patient-level metrics; and (iv) underpinning palliative care and NCD care with a rigorous and locally relevant evidence base demonstrating appropriate, feasible and effective care.

Abstract
Rationale Hospitalised patients with acute exacerbation of COPD may deteriorate despite treatment, with early readmission being common. Objectives To investigate whether neural respiratory drive, measured using second intercostal space parasternal muscle electromyography (EMGpara), would identify worsening dyspnoea and physician-defined inpatient clinical deterioration, and predict early readmission. Methods Patients admitted to a single-site university hospital with exacerbation of COPD were enrolled. Spirometry, inspiratory capacity (IC), EMGpara, routine physiological parameters, modified early warning score (MEWS), modified Borg scale for dyspnoea and physician-defined episodes of deterioration were recorded daily until discharge. Readmissions at 14 and 28 days post discharge were recorded. Measurements and main results 120 patients were recruited (age 70±9 years, forced expiratory volume in 1 s (FEV1) of 30.5±11.2%). Worsening dyspnoea, defined as at least one-point increase in Borg scale, was associated with increases in EMGpara%max and MEWS, whereas an increase in EMGpara%max alone was associated with physician-defined inpatient clinical deterioration. Admission-to-discharge change (Δ) in the normalised value of EMGpara (ΔEMGpara%max) was inversely correlated with ΔFEV1 (r=−0.38, p<0.001) and ΔIC (r=−0.44, p<0.001). ΔEMGpara%max predicted 14-day readmission (OR 1.13, 95% 1.03 to 1.23) in the whole cohort and 28-day readmission in patients under 85 years (OR 1.09, 95% CI 1.01 to 1.18). Age (OR 1.08, 95% CI 1.03 to 1.14) and 12-month admission frequency (OR 1.29, 1.01 to 1.66), also predicted 28-day readmission in the whole cohort. Conclusions Measurement of neural respiratory drive by EMGpara represents a novel physiological biomarker that may be helpful in detecting inpatient clinical deterioration and identifying the risk of early readmission among patients with exacerbations of COPD. Trial registration NCT01361451.

Benchmarking of a treatment planning system for spot scanning proton therapy: comparison and analysis of robustness to setup errors of photon IMRT and proton SFUD treatment plans of base of skull meningioma.

Abstract
PURPOSE Base of skull meningioma can be treated with both intensity modulated radiation therapy (IMRT) and spot scanned proton therapy (PT). One of the main benefits of PT is better sparing of organs at risk, but due to the physical and dosimetric characteristics of protons, spot scanned PT can be more sensitive to the uncertainties encountered in the treatment process compared with photon treatment. Therefore, robustness analysis should be part of a comprehensive comparison between these two treatment methods in order to quantify and understand the sensitivity of the treatment techniques to uncertainties. The aim of this work was to benchmark a spot scanning treatment planning system for planning of base of skull meningioma and to compare the created plans and analyze their robustness to setup errors against the IMRT technique. METHODS Plans were produced for three base of skull meningioma cases: IMRT planned with a commercial TPS [Monaco (Elekta AB, Sweden)]; single field uniform dose (SFUD) spot scanning PT produced with an in-house TPS (PSI-plan); and SFUD spot scanning PT plan created with a commercial TPS [XiO (Elekta AB, Sweden)]. A tool for evaluating robustness to random setup errors was created and, for each plan, both a dosimetric evaluation and a robustness analysis to setup errors were performed. RESULTS It was possible to create clinically acceptable treatment plans for spot scanning proton therapy of meningioma with a commercially available TPS. However, since each treatment planning system uses different methods, this comparison showed different dosimetric results as well as different sensitivities to setup uncertainties. The results confirmed the necessity of an analysis tool for assessing plan robustness to provide a fair comparison of photon and proton plans. CONCLUSIONS Robustness analysis is a critical part of plan evaluation when comparing IMRT plans with spot scanned proton therapy plans.

Abstract
Neisseria meningitidis is largely a commensal species, resident specifically in the human nasopharynx but can also cause endemic and epidemic disease. Type IV pili of N. meningitidis have long been implicated as important colonisation and virulence factors that initiate attachment to host cells. The major pilin subunit, of which thousands of copies make the pilus shaft, is thought to be important in contributing to the adhesive properties of the type IV pilus and has potential as a vaccine candidate against N. meningitidis. To further understand the major pilins role and potential therapeutic properties, a protocol to make soluble PilE, the major pilin of N.meningitidis, from a variety of strains was established; and the structure of PilE from strain MC58 was solved by X-ray crystallography. The structure of PilE was solved to 1.4Å resolution revealing a classic pilin fold indicating the pilus may have a similar super-structure to that of the closely related Neisseria gonorrhoeae. Immunisations were carried out in mice with the pilins from different strains of N. meningitidis. Preliminary results indicate the sera generated have no bactericidal activity but can discriminate between the two classes of major pilins. Future work aims to further investigate the properties of this sera and attempt structure solution of major pilins from different strains of N. meningitidis.

If you had less than a year to live, would you want to know? A seven-country European population survey of public preferences for disclosure of poor prognosis. Psychooncology 2013; 22:2298-305.

Abstract
OBJECTIVE With increasing European cancer deaths, clinicians must manage information regarding poor prognosis. This study aimed to determine European citizens' preferences, within a scenario of serious illness such as cancer with less than a year to live, for information disclosure regarding poor prognosis, the likely symptoms and problems, and the care options available, to measure variations between countries and to identify factors associated with preferences. METHODS A population-based cross-national telephone survey using random digit dialling in seven countries was conducted. RESULTS Among 9344 respondents, data revealed an international preference (73.9%) to always be informed in the scenario of having a serious illness such as cancer with less than a year to live. This varied from 67.6% in Italy to 80.7% in Flanders. A minority (21.1%) did not want such information unless they ask, or at all. People younger than 70 years (OR 0.72, 95% CI 0.62-0.83, p < 0.001), men (OR 1.23, 95% CI 1.10-1.37, p < 0.001), those with experience of illness (OR = 1.20. 95% CI 1.01-1.43, p < 0.05) and with more education (OR = 1.20, 95% CI 1.09-1.32, p < 0.001) were more likely to want to know of limited time left. CONCLUSIONS The models confirmed the influence of four factors in more than one country (age, gender, education and most concerning problem) and added 11 country-specific factors to which national policies and clinical practice should respond. These findings confirm a majority public preference to be informed in a scenario of poor prognosis. Policy clinical practice should facilitate elucidation and delivery of preferences. Evidence for effective communication skills-building interventions for clinicians is required.

Abstract
BACKGROUND Cancer end-of-life care (EoLC) policies assume people want to die at home. We aimed to examine variations in preferences for place of death cross-nationally. METHODS A telephone survey of a random sample of individuals aged ≥16 in England, Flanders, Germany, Italy, the Netherlands, Portugal and Spain. We determined where people would prefer to die if they had a serious illness such as advanced cancer, facilitating circumstances, personal values and experiences of illness, death and dying. RESULTS Of 9344 participants, between 51% (95% CI: 48% to 54%) in Portugal and 84% (95% CI: 82% to 86%) in the Netherlands would prefer to die at home. Cross-national analysis found there to be an influence of circumstances and values but not of experiences of illness, death and dying. Four factors were associated with a preference for home death in more than one country: younger age up to 70+ (Germany, the Netherlands, Portugal, Spain), increased importance of dying in the preferred place (England, Germany, Portugal, Spain), prioritizing keeping a positive attitude (Germany, Spain) and wanting to involve family in decisions if incapable (Flanders, Portugal). CONCLUSIONS At least two-thirds of people prefer a home death in all but one country studied. The strong association with personal values suggests keeping home care at the heart of cancer EoLC.

Abstract
OBJECTIVE To examine and compare doctors' and nurses' views and experiences regarding outcome measurement in palliative care, including patient-reported outcome measures (PROMs). METHODS A web-based survey developed through expert review and piloting was conducted in Europe and Africa with palliative care professionals working in clinical care, audit and research. RESULTS The overall participation rate was 42% (663/1592) and the overall completion rate was 59% (392/663). Of these respondents, 196 were doctors (51% male, mean 47 years) and 104 were nurses (84% female, mean 45 years). Doctors' most common reported reasons for not using tools were time constraints followed by lack of training. For nurses, it was lack of training followed by time constraints. Provision of information and guidance influenced willingness to use measures. For those that used tools, most reported favourable outcome measurement experiences. Both prioritized brief PROMs, and measures that included physical and psychological domains. For clinical purposes, the main advantage for doctors was assessment/screening, and clinical decision making for nurses. For research, doctors were most influenced by a measure's comparability with national/international literature followed by its validation in palliative care. For nurses, validation in palliative care was followed by tool access. CONCLUSION Overall these respondents shared similar views and experiences, and both were influenced by similar factors. Multidisciplinary outcome measurement education and training is feasible and required. Multidimensional and brief PROMs that include physical and psychological domains need to be prioritized, and access to freely available, validated and translated tools is needed to ensure cross-national comparisons and coordination of international research.

Abstract
OBJECTIVES The aim of the study was to explore levels of doctor-patient concordance during the making of decisions regarding HIV treatment switching and stopping in relation to patient health-related outcomes. METHODS Adult patients attending five HIV clinics in the United Kingdom were requested to complete the study questionnaire, which included a Concordance Scale, and measures of symptoms [Memorial Symptom Assessment Short Form (MSAS) index], quality of life (EuroQol), satisfaction, adherence and sexual risk behaviour. Clinical health measures (HIV viral load and CD4 cell count) were also obtained. A total of 779 patients completed the questionnaire, giving a response rate of 86%; of these 779 patients, 430 had switched or stopped their HIV treatment and were thus eligible for inclusion. Of these patients, 217 (50.5%) fully completed the Concordance Scale. RESULTS Concordance levels were high (88% scored between 30 and 40 on the scale; score range 10-40). Higher concordance was related to several patient outcomes, including: better quality of life (P=0.003), less severe and burdensome symptom experience (lower MSAS-physical score, P=0.001; lower MSAS-psychological score, P=0.008; lower MSAS-global distress index score, P=0.011; fewer symptoms reported, P=0.007), higher CD4 cell count (at baseline, P=0.019, and 6-12 months later, P=0.043) and greater adherence (P=0.029). CONCLUSIONS High levels of doctor-patient concordance in HIV treatment decision-making are associated with greater adherence and better physical and psychological functioning. More research is needed to establish a causal relationship between concordance and these outcomes.
