Models of care in secure services for people with intellectual and developmental disability: Implementing the Walkway to Wellness.

BACKGROUND: Changes to policy around inpatient services for people with intellectual and developmental disability (IDD) who offend, have led to a need for services to reconsider their models of care. This has led to calls for more tailored, patient-centred care models, with less reliance solely on offence-related treatment programmes which can be unsuitable for a growing proportion of patients with more complex cognitive and behavioural difficulties. In response, the Walkway to Wellness (W2W) was developed at one National Health Service Trust providing secure services to people with IDD, with the intention of delivering a more collaborative, co-produced and goal-oriented care model that was better understood by staff and patient stakeholders. AIMS: To evaluate the implementation of the W2W using Normalisation Process Theory (NPT), an evidence-based theoretical approach is used across a number of health settings. METHODS: Staff were invited to complete a short questionnaire, using the NPT informed Normalisation Measure Development questionnaire, at two time points along the implementation process. Patients were invited to complete a simplified questionnaire. Both groups were asked for their views on the W2W and the process of its implementation. RESULTS: Although the W2W was more familiar to staff at the second time point, scores on the four NPT constructs showed a trend for it being less embedded in practice, with significant results concerning the ongoing appraisal of the new model. Patient views were mixed; some saw the benefit of more goal-oriented processes, but others considered it an additional chore hindering their own perceived goals. CONCLUSION: Early involvement of all stakeholders is required to enhance the understanding of changes to models of care. Live feedback should be used to refine and revise the model to meet the needs of patients, carers and staff members.

A systematic review and narrative analysis of digital speech biomarkers in Motor Neuron Disease.

Motor Neuron Disease (MND) is a progressive and largely fatal neurodegeneritve disorder with a lifetime risk of approximately 1 in 300. At diagnosis, up to 25% of people with MND (pwMND) exhibit bulbar dysfunction. Currently, pwMND are assessed using clinical examination and diagnostic tools including the ALS Functional Rating Scale Revised (ALS-FRS(R)), a clinician-administered questionnaire with a single item on speech intelligibility. Here we report on the use of digital technologies to assess speech features as a marker of disease diagnosis and progression in pwMND. Google Scholar, PubMed, Medline and EMBASE were systematically searched. 40 studies were evaluated including 3670 participants; 1878 with a diagnosis of MND. 24 studies used microphones, 5 used smartphones, 6 used apps, 2 used tape recorders and 1 used the Multi-Dimensional Voice Programme (MDVP) to record speech samples. Data extraction and analysis methods varied but included traditional statistical analysis, CSpeech, MATLAB and machine learning (ML) algorithms. Speech features assessed also varied and included jitter, shimmer, fundamental frequency, intelligible speaking rate, pause duration and syllable repetition. Findings from this systematic review indicate that digital speech biomarkers can distinguish pwMND from healthy controls and can help identify bulbar involvement in pwMND. Preliminary evidence suggests digitally assessed acoustic features can identify more nuanced changes in those affected by voice dysfunction. No one digital speech biomarker alone is consistently able to diagnose or prognosticate MND. Further longitudinal studies involving larger samples are required to validate the use of these technologies as diagnostic tools or prognostic biomarkers.

Genetic diversity of porcine group A rotavirus strains in the UK.

Rotavirus is endemic in pig farms where it causes a loss in production. This study is the first to characterise porcine rotavirus circulating in UK pigs. Samples from diarrheic pigs with rotavirus enteritis obtained between 2010 and 2012 were genotyped in order to determine the diversity of group A rotavirus (GARV) in UK pigs. A wide range of rotavirus genotypes were identified in UK pigs: six G types (VP7); G2, G3, G4, G5, G9 and G11 and six P types (VP4); P[6], P[7], P[8], P[13], P[23], and P[32]. With the exception of a single P[8] isolate, there was less than 95% nucleotide identity between sequences from this study and any available rotavirus sequences. The G9 and P[6] genotypes are capable of infecting both humans and pigs, but showed no species cross-over within the UK as they were shown to be genetically distinct, which suggested zoonotic transmission is rare within the UK. We identified the P[8] genotype in one isolate, this genotype is almost exclusively found in humans. The P[8] was linked to a human Irish rotavirus isolate in the same year. The discovery of human genotype P[8] rotavirus in a UK pig confirms this common human genotype can infect pigs and also highlights the necessity of surveillance of porcine rotavirus genotypes to safeguard human as well as porcine health.

Topical calcitriol is degraded by ultraviolet light.

Calcitriol ointment has been approved for the treatment of psoriasis in many countries around the world. It may be prescribed in conjunction with phototherapy. Our purpose was to evaluate the effect of various therapeutic ultraviolet modalities on the stability of calcitriol and, conversely, to study the effects of calcitriol ointment on transmission of different forms of ultraviolet light. Calcitriol ointment 3 microg per g was irradiated with 10 J per cm2 ultraviolet A, 100 mJ per cm2 broadband ultraviolet B, and 3.0 J per cm2 narrowband ultraviolet B, and its stability was compared with samples exposed to fluorescent light and ambient sunlight. Ultraviolet A and ultraviolet B transmission were measured through thin and thick layers of calcitriol 3 microg per g ointment and vehicle. More than 90% of calcitriol ointment is degraded upon exposure to ultraviolet A, broadband ultraviolet B, and narrowband ultraviolet B. Transmission of ultraviolet A is reduced through calcitriol ointment and its vehicle by 17%-31% and 17%-41%, respectively. Transmission of ultraviolet B is reduced by 67%-87% through vehicle and 50%-83% through calcitriol ointment. When used in conjunction with phototherapy, calcitriol ointment should be applied after ultraviolet exposure, not before. Calcipotriene, the only vitamin D analog already approved for psoriasis in the USA, has been used successfully in combination with ultraviolet B and psoralen plus ultraviolet A.
