Effectiveness and cost-effectiveness of a patient-initiated botulinum toxin treatment model for blepharospasm and hemifacial spasm: a study protocol for a randomised controlled trial
Background
Blepharospasm and hemifacial spasm are debilitating conditions that significantly impact on patient quality of life. Cyclical treatment with botulinum toxin injections offers temporary relief, but the duration of treatment efficacy is variable. The standard model of patient care defines routine fixed-time based scheduled treatment cycles which may lead to unnecessarily frequent treatment for some patients and experience of distressing symptoms in others, if symptoms return before the scheduled follow-up period.
Methods/Design
A randomised controlled trial will compare a patient-initiated model of care, where patients determine botulinum toxin treatment timing, to the standard model of care in which care is scheduled by the clinical team. A sample of 266 patients with blepharospasm or hemifacial spasm will be recruited from Moorfields Eye Hospital (MEH), London. The trial will be accompanied by a mixed methods evaluation of acceptability of the new service. Patients who meet eligibility criteria will be assessed at baseline and those in the intervention group will be provided instructions on how to book their own treatment appointments. Patients in both groups will be followed up 3 and 9 months into the trial and all patients will be returned to usual care after 9 months to meet safety protocols. Primary outcome measures include disease severity (questionnaire), functional disability (questionnaire) and patient satisfaction with care (questionnaire). Secondary outcomes include disease-specific quality of life (questionnaire), mood (questionnaire), illness and treatment perceptions (questionnaire and semi-structured interviews), economic impact (questionnaire) and acceptability (questionnaire and semi-structured interviews).
Discussion
This trial will assess the effectiveness and cost-effectiveness of a patient-led care model for botulinum toxin therapy. If the new model is shown to be effective in reducing distress and disability in these populations and is found to be acceptable to patients, whilst being cost-effective, this will have significant implications for service organisation across the NHS.

The relationships between self-compassion, attachment and interpersonal problems in clinical patients with mixed anxiety and depression and emotional distress
Self-compassion has been consistently linked to psychological well-being. The ability to be self-compassionate may be shaped by early attachment experiences and associated with interpersonal difficulties. However, evidence has yet to be extended to clinical populations. This study examined the role of self-compassion and its relationship with attachment and interpersonal problems in clinical patients with anxiety and depression. Participants (N = 74; 60% female, mean age 40 years) were recruited from a primary care psychological therapies service in Scotland, UK. Participants completed four self-report questionnaires assessing self-compassion, attachment, interpersonal problems and emotional distress (including depression and anxiety). Low self-compassion, attachment-related avoidance (but not attachment-related anxiety) and high interpersonal problems were all associated with higher levels of emotional distress and anxiety. Low self-compassion and high interpersonal problems were predicted by attachment-related avoidance. Self-compassion mediated the relationship between attachment-related avoidance and emotional distress and anxiety. This was a cross-sectional design and therefore a definitive conclusion cannot be drawn regarding causal relationships between these variables. Self-reported questionnaires were subject to response bias. This study has extended the evidence base regarding the role of self-compassion in patients with clinical levels of depression and anxiety. Notably, our findings indicated that self-compassion may be a particularly important construct, both theoretically and clinically, in understanding psychological distress amongst those with higher levels of attachment avoidance. This study supports the development and practice of psychotherapeutic approaches, such as compassion-focused therapy for which there is a growing evidence base
Dust and star formation properties of a complete sample of local galaxies drawn from the Planck Early Release Compact Source Catalogue
We combine Planck High Frequency Instrument data at 857, 545, 353 and 217 GHz with data from Wide-field Infrared Survey Explorer (WISE), Spitzer, IRAS and Herschel to investigate the properties of a well-defined, flux-limited sample of local star-forming galaxies. A 545 GHz flux density limit was chosen so that the sample is 80 per cent complete at this frequency, and the resulting sample contains a total of 234 local, star-forming galaxies. We investigate the dust emission and star formation properties of the sample via various models and calculate the local dust mass function. Although single-component-modified blackbodies fit the dust emission longward of 80 \u3bcm very well, with a median \u3b2 = 1.83, the known degeneracy between dust temperature and \u3b2 also means that the spectral energy distributions are very well described by a dust component with dust emissivity index fixed at \u3b2 = 2 and temperature in the range 10-25 K. Although a second, warmer dust component is required to fit shorter wavelength data, and contributes approximately a third of the total infrared emission, its mass is negligible. No evidence is found for a very cold (6-10 K) dust component. The temperature of the cold dust component is strongly influenced by the ratio of the star formation rate to the total dust mass. This implies, contrary to what is often assumed, that a significant fraction of even the emission from \u2dc20 K dust is powered by ongoing star formation, whether or not the dust itself is associated with star-forming clouds or `cirrus'. There is statistical evidence of a free-free contribution to the 217 GHz flux densities of 7220 per cent. We find a median dust-to-stellar mass ratio of 0.0046; and that this ratio is anticorrelated with galaxy mass. There is good correlation between dust mass and atomic gas mass (median Md/MHI = 0.022), suggesting that galaxies that have more dust (higher values of Md/M*) have more interstellar medium in general. Our derived dust mass function implies a mean dust mass density of the local Universe (for dust within galaxies), of 7.0 \ub1 1.4
7 105 M 99 Mpc-3, significantly greater than that found in the most recent estimate using Herschel data. \ua9 2013 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society
Declines in sexual activity and function predict incident health problems in older adults: prospective findings from the English Longitudinal Study of Ageing
The objective of this study was to investigate cross-sectional and longitudinal associations between declines in sexual activity and function and health outcomes in a large population-based sample of older adults. Data were from 2577 men and 3195 women agedââ„â50 years participating in the English Longitudinal Study of Ageing. Past-year changes in sexual desire, frequency of sexual activity, and ability to have an erection (men)/become sexually aroused (women) were assessed at baseline by self-completion questionnaire. Health outcomes (self-rated health, limiting long-standing illness, doctor-diagnosed diseases of the vascular system, and cancer) were self-reported at baseline (2012/2013) and 4-year follow-up (2016/2017). Data were analyzed using logistic regression, adjusted for sociodemographics, health behaviors, and depressive symptoms. Prospectively, men who reported a decline in sexual desire had higher odds of incident limiting long-standing illness (ORâ1.41, 95% CI 1.04â1.91) and incident cancer (ORâ1.63, 95% CI 1.06â2.50) than those who maintained their sexual desire. Men who reported a decline in the frequency of sexual activities had higher odds of deterioration in self-rated health (ORâ1.47, 95% CI 1.04â2.08) and incident limiting long-standing illness (ORâ1.69, 95% CI 1.20â2.37). In women, a decline in frequency of sexual activities was associated with deterioration of self-rated health (ORâ1.64, 95% CI 1.07â2.51). Erectile dysfunction was longitudinally associated with poorer health outcomes including incident cancer (ORâ1.73, 95% CI 1.11â2.70), coronary heart disease (ORâ2.29, 95% CI 1.29â4.07), and fair/poor self-rated health (ORâ1.66, 95% CI 1.19â2.32). Practitioners should be mindful that a decline in sexual activity, desire, or function in older age may be an important indicator of future adverse health outcomes
Conviviality by design : the socio-spatial qualities of spaces of intercultural urban encounters
This paper presents findings from a mixed-method research project which explored use of outdoor spaces and social connections in Bradford, a post-industrial city in the north of England with a highly ethnically diverse population. Data was collected through micro-scale behavioural mapping of public spaces (analysed using GIS) and both on-site and in-depth interviews. The integration of these methods allows a focus on intersectional identities and social values for everyday conviviality situated in different typologies of public open spaces (parks, squares, streets) in city centre and suburban neighbourhoods. The analysis offers nuanced insights into the socio-spatial aspects of conviviality: patterns of activity by diverse users, situations in which encounters are prompted, and the implications of negotiating differences in relation to perceptions of self, others, and the environment. We discuss the relevance of the urban public realm for shared understandings of diversity, qualities of visibility, lingering and playfulness, and the importance of threshold spaces. We explore racialised and excluding experiences and how these relate to mobility and territorial patterns of use, specifically with relation to gender. The paper highlights connections between intercultural encounters and urban design practice, with implications for well-being and integration in ethnically diverse urban areas
Fluorescent amino acids as versatile building blocks for chemical biology
Fluorophores have transformed the way we study biological systems, enabling non-invasive studies in cells and intact organisms, which increase our understanding of complex processes at the molecular level. Fluorescent amino acids have become an essential chemical tool because they can be used to construct fluorescent macromolecules, such as peptides and proteins, without disrupting their native biomolecular properties. Fluorescent and fluorogenic amino acids with unique photophysical properties have been designed for tracking proteinâprotein interactions in situ or imaging nanoscopic events in real time with high spatial resolution. In this Review, we discuss advances in the design and synthesis of fluorescent amino acids and how they have contributed to the field of chemical biology in the past 10 years. Important areas of research that we review include novel methodologies to synthesize building blocks with tunable spectral properties, their integration into peptide and protein scaffolds using site-specific genetic encoding and bioorthogonal approaches, and their application to design novel artificial proteins, as well as to investigate biological processes in cells by means of optical imaging.

Deliberate self-harm and attachment: mediating and moderating roles of depression, anxiety, social support and interpersonal problems among Pakistani school going adolescents
Introduction: In Pakistan there is dearth of research on deliberate self-harm (DSH) and
its predictors among adolescents. While the lack of research in Pakistan can be partly
attributed to the sacrilegious status, criminalization and stigmatization attached to DSH, it
is also an attribute of paucity of Urdu versions of the standardized psychological
instruments. Previous research in developed countries has indicated that attachment theory
can be used as a useful framework to understand the development of austere
psychopathologies like DSH, as well as for studying pathways of interaction of
interpersonal and intrapersonal factors of psychopathologies. In this study, standardized
psychological instruments are translated into Urdu language as a first step. These
instruments are then used to study pathways of interaction of interpersonal and
intrapersonal factors of DSH, conceptualized within attachment framework.
Method: The study was conducted in two steps. In step 1, Youth Health Risk Behavior
Survey (YHRB), Inventory of Interpersonal Problems-32 (IIP-32) and Significant Others
Scale (SOS), were translated into Urdu language. Along with these scales, Urdu translated
versions of Hospital Anxiety and Depression Scale (HADS), Adolescent Relationship
Scales Questionnaire (ARSQ), Life Events scale (LES) from CASE questionnaire and
Family Affluence Scale-II (FAS-II) were reviewed for accuracy of translation through
expert judgement and psychometric evaluation. Secondly, a cross sectional survey was
conducted with 1290 adolescents (10 - 19 years age) using the translated Urdu versions of
the instruments and demographic pro forma. Structural equation modelling was used to
study the pathways of associations between predictors of DSH.
Results: The extensive process of translation resulted in establishment of semantic,
content, technical and construct equivalence of the translated instruments with the original
English versions. Multiple imputation was performed to account for missing values in
SPSS 20. Important structural adaptations were made in the scales based on factor analyses
conducted in M plus. After modifications, all scales showed satisfactory CFI (â„ 0.90) and
RMSEA (†0.06). Results of the survey indicated that the prevalence of DSH (with, without
and ambivalent suicidal intentions) was 7%. Two SEM models were constructed involving
both mediation and moderation pathways. Results of Model 1 showed association of
attachment with DSH was double mediated by social support, depression and anxiety.
Model 2 also confirmed association of attachment with DSH with double mediation
through relationship style problems, depression and anxiety. In order to understand the
contextual picture of the concepts studied in this research both SEM models were also
constructed by controlling for demographic factors. This resulted in confirming age,
gender and family affluence as significant contributors but with very small effects.
Discussion and conclusion: In the present study translation of the instruments helped in
building a reservoir for future research. The results of translation and validation of
instruments indicated that cultural differences, language needs and age must be accounted
for while using standardized psychological instruments. Taking into consideration specific
cultural and demographic background of Pakistan, this study also confirms the key role of
attachment in influencing interaction of predictors of DSH. It is suggested that
intrapersonal and interpersonal factors are influential points of intervention for designing
clinical, school and community based awareness and prevention programs for DSH. The
thesis also discusses the implications for policy guidelines along with recommendations
for future research and other applications of the study
L'Italia come modello per l'Europa e per il mondo nelle politiche sanitarie per il trattamento dell'epatite cronica da HCV
The World Health Organization foresees the
elimination of HCV infection by 2030. In light of this and the curre
nt, nearly worldwide, restriction in direct-acting agents
(DAA) accessibility due to their high price, we aimed to evaluate
the cost-effectiveness of two alternative DAA treatment
policies: Policy 1 (universal): treat all patients, regardless of the fibrosis stage; Policy 2 (prioritized): treat only priori
tized
patients and delay treatment of the
remaining patients until reaching stage F3. T
he model was based on patientâs data
from the PITER cohort. We demonstrated that extending HC
V treatment of patients in any fibrosis stage improves health
outcomes and is cost-effective
