To understand participant perspectives on an effective, practical, comprehensive telehealth intervention for persistently poorly controlled diabetes mellitus and examine how its components contributed to improved outcomes, with the goal of informing broader telehealth-based diabetes management strategies.
Methods:
We conducted semi-structured interviews of a purposive sample of patients and staff in the comprehensive telehealth arm of the Practical Telehealth to Improve Control and Engagement for Patients with Clinic-Refractory Diabetes Mellitus study. Using the lens of patient engagement, we applied directed content analysis to categorize themes across the five components of the intervention.
Results:
The purposive sample included 19 patients (79% male, 53% Black, varying levels of intervention engagement) and 8 staff. The telemonitoring component was associated with encouragement and motivation among patients; staff found satisfaction in providing metrics of success for participants. For the self-management component, patients saw staff as helpful with problem-solving; staff felt patients were receptive to education. Medication management supported medication adherence and optimization and was acceptable to patients. Diet/activity support motivated behavioral changes among patients. Staff felt that depression support allowed for responsiveness to medical and behavioral factors influencing self-management. Identified areas for improvement included staff time constraints, patient difficulties with taking and transmitting data, and challenges with patient adherence among those with mental health conditions.
Conclusion:
Findings from this study provide insights that may inform the design, implementation, and scalability of comprehensive telehealth models for diabetes management across diverse healthcare settings.
Patients’ beliefs and attitudes about medications play a role in whether they adhere to their medications or not. Knowledge on how beliefs and attitudes about medications can be influenced is therefore important.
Objectives
The current study aimed to assess whether patients’ perceived support from their therapists regarding use of medications was associated with their beliefs and attitudes about medications. Because non-adherence in patients with psychosis frequently results in relapses and emergencies, this knowledge may be very useful for therapists and patients.
Methods
This cross-sectional study included 310 patients diagnosed with psychosis from 31 clinical units in Norwegian mental health specialist care. We assessed beliefs about medications using the Beliefs about Medicines Questionnaire (BMQ). BMQ-specific consists of two subscales, BMQ-necessity and BMQ-concerns. Higher score on the necessity subscale indicates stronger beliefs in the necessity of taking the medicine. Higher score on the concern subscale indicates stronger concerns about taking the medicine. We used a newly developed self-report questionnaire, MedSupport, to assess the patients’ perceived support from therapists in dealing with their medications. Higher score on the MedSupport means that the patient experienced more support with decisions related to medications. Linear mixed effect models were used to investigate possible associations of sociodemographic factors, clinical factors and patients’ perceptions of medication support with BMQ.
Results
Patients’ perceptions of medication support from therapists were positively associated with positive beliefs towards medications, β = 0.20, 95% CI [0.04 to 0.35], p=0.012, and negatively associated with concerns about taking the medications, β = -0.31, 95% CI [-0.44 to -0.17], p < 0.001, when other relevant variables were taken into consideration.
Conclusions
The present study shows that therapists may affect patients’ beliefs and concerns about medications. Consequently, medication support may lead to improved adherence to medications prescribed.
A precision medicine approach to clozapine dosing aims to personalise it in two ways: i) during titration, and ii) for succeeding dose adjustments. This requires valid models of dose/concentration relationships, but cross-sectional models suffer from population-level artefacts and individual problems due to poor adherence or stopping smoking. Longitudinal data sets from two mental health trusts allowed poor adherence and smoking cessation to be identified. We then modelled dose/concentration relationships to construct personalised targets for i) and ii).
Methods
Demographics and co-prescribed medication were recorded for 137 patients from Greater Manchester Mental Health (GMMH) Trust who had two or more successive plasma levels and doses from 2016–2018. 412 patients from Pennine Care Foundation Trust (PCFT) who had successive plasma levels and doses from 2009–2023 were also recorded. In each sample, adherent patients (88 from GMMH and 371 from PCFT) were identified after excluding: > two-fold variation between blood samples in clozapine/norclozapine ratios, > two-fold variation in dose/concentration ratios, a clozapine/norclozapine ratio > 3, or a dose/concentration ratio > two standard deviations from the sample mean. Those whose smoking status (smoker vs non-smoker) changed between samples were excluded.
To identify i) titration targets, we used raw data in first samples (checked with logistic regression) to identify dose thresholds which produced most levels above 0.35 μg/ml (therapeutic) and no levels greater than 1 μg/ml (toxic). To model ii) effective dose adjustment, we used the equation Dt = Dc(Ct/Cc) to identify the most effective dose for the second samples. Dt was target dose, Dc current dose, Ct target level (0.45 μg/ml), and Cc current level.
Results
First sample dose/concentration ratio in adherent patients correlated r > 0.75 with second samples’ dose/concentration. >84% of plasma levels were within 20% of the mean across both samples.
i. The GMMH dataset titration targets were 325 mg, 300 mg, 225 mg, and 175 mg daily for male smokers, female smokers, male non-smokers, and female non-smokers, respectively. In PCFT, data suggested corresponding targets of 375 mg, 325 mg, 225 mg and 175 mg. Targets avoided toxicity and gave therapeutic levels in > 50% of cases.
ii. Target dose, ascertained using the equation, and actual second dose were compared: in adherent cases, toxicity only occurred when actual doses were 1.5-fold greater than target dose, and above target all plasma levels exceeded 0.35 μg/ml in GMMH. PCFT data appeared similar.
Conclusion
Relatively safe and effective titration targets for smokers and non-smokers from both sexes were identified. A simple equation would improve precision and effectiveness of dose adjustment thereafter.
Background: Hypothalamic hamartomas (HH) are a challenging cause of seizure in children, partly because the neural circuitry involved in ictogenesis is incompletely understood. We review our institutions’ use of magnetic resonance imaging-guided laser interstitial thermal therapy (MRgLITT) to treat hypothalamic hamartoma (HH) with resting-state fMRI performed immediately before and after ablation. Methods: Seed-based whole brain connectivity to thalamic regions of interest was performed immediately pre- and post- MRgLITT. Multivariable generalized linear models were used to correlate resting-state data with seizure outcomes. Results: Eight patients underwent MRgLITT treatments for HH, with a mean follow up of 29 months. Four patients (50%) were seizure free at 12 months and two (25%) had a significant improvement in seizure frequency. We identified reduced thalamocortical connectivity involving the anterior cingulate and posterior parietal regions, consistent with disconnection of the mammillothalamic tract and interruption of Papez circuit. Large-scale thalamocortical connectivity changes were driven by children who subsequently became seizure free. Conclusions: Disconnection of the mammillothalamic tract and interruption of thalamic circuitry in patients undergoing MRgLITT for HH appears to be associated with improved seizure outcomes. The ability to assess network changes immediately post- MRgLITT could enable operative adjustments to be made mid-procedure to optimize seizure outcome in real time.
The Tilburg Frailty Indicator (TFI) is a validated tool for determining frailty in older adults. This study examined the validity and accuracy of the TFI Part B (TFI-B) in a North American context. Seventy-two individuals ≥ 65 years of age recruited from a rural geriatric medicine clinic completed a set of self-reported and performance-based measures, including TFI-B. Frailty level was determined using modified Fried’s Frailty Phenotype (FFP). Pearson correlation coefficients (r) assessed the concurrent relationships between the TFI-B and other measures. Accuracy of the TFI-B in classifying frailty level was assessed using assessing area under the curve (AUC). The TFI-B scores showed low correlations (r < 0.4) with gait speed and grip, suggesting that the TFI-B did not consider frailty as merely a physical problem. The AUC of 0.82 indicated that the TFI-B scores accurately classified frail versus non-frail individuals. The score of ≥ 5 on the TFI-B scores showed satisfactory sensitivity/specificity (73%/77%) and excellent negative predictive value (91.95%). This indicates that a TFI-B score of < 5 can be used to rule out frailty.
Injurious feather pecking in non-cage systems is a serious economic and welfare concern for the egg-producing industry. Here, we describe the first results from an ongoing collaborative project to improve range environment and welfare of laying hens (Gallus gallus domesticus) within the McDonald's Restaurants Ltd, UK supply base. The objective of this study was to investigate, in a commercial situation, the correlation between: i) proportion of range cover and ii) proportion of canopy cover, with plumage damage of end-of-lay hens. The assessment of plumage damage due to injurious feather pecking is a key animal-based welfare indicator for laying hens in non-cage systems. In 2007 and 2008, all laying-hen producers within the McDonald's Restaurants Ltd egg-supply base, were required to plant (if not present already), 5% of the total range area with blocks of trees ether side, and between 20-25 m from the laying hen house. Plumage damage at end of lay was positively correlated with mortality and flocks depleted in summer had less plumage damage at end of lay than flocks depleted in autumn or winter, possibly because of weather conditions at the time of placement. There was no correlation between the proportion (5-90%) of range cover and plumage damage at the end of lay, however, plumage damage was negatively correlated with percent of canopy cover within tree-planted areas. Providing a minimum of 5% tree cover, planted close to the house but with good canopy coverage, may be a feasible and practical method enabling producers to reduce plumage damage due to injurious feather pecking in their laying-hen flocks. Tree cover provision may also provide environmental benefits, such as soil stabilisation, reduced nutrient leaching and carbon sequestration.
Background: Infantile spasms (IS) is an epileptic encephalopathy, characterized by spasms, hypsarrhythmia, and developmental regression. This is a retrospective case series of children with IS who underwent epilepsy surgery at The Hospital for Sick Children (HSC) in Toronto, Canada. Methods: The records of 223 patients seen in the IS clinic were reviewed. Results: Nineteen patients met inclusion criteria. The etiology of IS was encephalomalacia in six patients (32%), malformations of cortical development in 11 patients (58%), atypical hypoglycaemic injury in one patient (5%), and partial hemimegalencephaly in one patient (5%). Nine patients (47%) underwent hemispherectomy and 10 patients (53%) underwent lobectomy/lesionectomy. Three patients (16%) underwent a second epilepsy surgery. Fifteen patients (79%) were considered ILAE Seizure Outcome Class 1 (completely seizure free; no auras). The percentage of patients who were ILAE Class 1 at most recent follow-up decreased with increasing duration of epilepsy prior to surgery. Developmental outcome was improved in 14/19 (74%) and stable in 5/19 (26%) patients. Conclusions: Our study found excellent seizure freedom rates and improved developmental outcomes following epilepsy surgery in patients with a history of IS with a structural lesion detected on MRI brain.
Psychological therapy is core component of mental healthcare. However, many people with severe mental illnesses do not receive therapy, particularly in acute mental health settings.
Aims
This study identifies barriers to delivering and accessing psychological therapies in acute mental health settings, and is the first to recommend how services can increase access from the perspectives of different stakeholders (staff, patients and carers).
Method
Sixty participants with experiences of acute mental health wards (26 staff, 22 patients and 12 carers) were interviewed about barriers to accessing therapy in in-patient settings and how therapies should be delivered to maximise access.
Results
Four themes were identified: (a) ‘Models of care’, including the function of in-patient wards, beliefs about the causes of mental health problems and the importance of strong leadership to support psychosocial interventions; (b) ‘Integrated care’, including the importance of psychologists being ward-based, as well as having strong links with community teams; (c) ‘Acute levels of distress’, including factors that aggravate or ameliorate the impact of this on engagement in therapy; and (d) ‘Enhancing staff capability and motivation’, which is influenced by contextual issues.
Conclusions
It is possible to improve access to therapy through strong leadership (that is supportive of talking treatments), flexible delivery of therapy (that considers short admissions) and a whole-systems approach that promotes ward staff understanding of the psychosocial causes of mental illness and staff well-being. It is essential to ensure continuity between in-patient and community therapy services, and for wards to have physical space to carry out therapy.
The coronavirus disease 2019 pandemic has greatly disrupted head and neck cancer services in the West of Scotland. This study aimed to assess the impact of the first wave of the pandemic on cancer waiting times.
Methods
A retrospective review of multidisciplinary team records was undertaken between March and May in 2019 and the same months in 2020. Time-to-diagnosis and time-to-treatment for new cancers treated with curative intent were compared between the study periods, and subclassified by referral pathway.
Results
A total of 236 new cancer patients were included. During the pandemic, pathways benefitted from reduced diagnostic and treatment times resulting from the restructuring of service provisions. A 75 per cent reduction in secondary care referrals and a 33 per cent increase in urgent suspicion of cancer referrals were observed in 2020.
Conclusion
Head and neck cancer pathway times did not suffer because of the coronavirus pandemic. Innovations introduced to mitigate issues brought about by coronavirus benefitted patients, led to a more streamlined service, and improved diagnostic and treatment target compliance.
Background: Infantile spasms (IS) is an epileptic encephalopathy, characterized by epileptic spasms, hypsarrhythmia, and developmental regression. This is a retrospective case series detailing the experience in children with IS who have undergone epilepsy surgery at The Hospital for Sick Children (HSC). Methods: Records of 223 patients from HSC were reviewed. Patients were included if they had a current or previous history of IS with a lesion detected on MRI/PET scan who underwent epilepsy surgery. Results: Nineteen patients were included. The etiology of IS was encephalomalacia in six patients (32%), malformations of cortical development in 11 patients (58%), atypical hypoglycaemic injury in one patient (0.5%), and partial hemimegalencephaly in one patient (0.5%). The median age at the onset of IS was five months. The median age at surgery was 18 months. Nine patients (47%) underwent hemispherectomy and 10 patients (53%) underwent lobectomy/lesionectomy. Fifteen patients (79%) were considered ILAE Seizure Outcome Class 1. Developmental outcome was improved in 14/19 (74%) and stable in 5/19 (26%) patients. Conclusions: Even with a generalized EEG pattern such as hypsarrhythmia, patients should be considered for focal resective surgery. Early surgical intervention shortens the duration of active epilepsy thus limiting the potentially irreversible effects of on-going seizures.
This article reports on a new project to investigate the activities of early Homo sapiens in the area of the Chotts ‘megalake’ in southern Tunisia. Excavations in 2015 and 2019 at Oued el Akarit revealed one of a number of Middle Stone Age (MSA) horizons near the top of a long sequence of Upper Pleistocene deposits. The site identified as Oued el Akarit (Sondage 8) consists of lithic artefacts, bone fragments of large ungulates and pieces of ostrich eggshell. Many of the objects are burnt. Excavation of about nine square metres revealed that these were associated with a lightly trampled and combusted occupation surface. Amongst the identified artefacts were Levallois flakes some of which could be refitted, thereby indicating the generally undisturbed nature of the occupation. The lithic finds also included side scrapers and other tools diagnostic of the MSA but significantly no bifacial or tanged tools. OSL (Optically Stimulated Luminescence) dating of the sediments and AMS (Accelerator Mass Spectrometry) radiocarbon dating of ostrich eggshell have produced uncalibrated age determinations in the range 37,000–40,000 years ago, one of the youngest ages for MSA sites in the region. This is the first example of a securely dated later MSA occupation in a riparian environment in south-eastern Tunisia.
Metformin is widely used in pregnancy, despite lack of long-term safety for children. We hypothesised that metformin exposure in utero is associated with increased cardiovascular risk. We tested this hypothesis in a follow-up study of children born to obese mothers who had participated in a randomised controlled trial of metformin versus placebo in pregnancy (EMPOWaR). We measured body composition, peripheral blood pressure (BP), arterial pulse wave velocity and central haemodynamics (central BP and augmentation index) using an oscillometric device in 40 children of mean (SD) age 5.78 (0.93) years, exposed to metformin (n = 19) or placebo (n = 21) in utero. There were no differences in any of the anthropometric or vascular measures between metformin and placebo-exposed groups in univariate analyses, or after adjustment for potential confounders including the child’s behaviour, diet and activity levels. Post-hoc sample size calculation indicated we would have detected large clinically significant differences between the groups but would need an unfeasible large number to detect possible subtle differences in key cardiovascular risk parameters in children at this age of follow-up. Our findings suggest no evidence of increased cardiovascular risk in children born to obese mothers who took metformin in pregnancy and increase available knowledge of the long-term safety of metformin on childhood outcomes.
A standard framework for business ethics views the inquiry as an application of major ethical theories to specific issues in business. As these theories are largely presented as being principled, the exercise therefore becomes one of applying general principles to business situations. Many adopting this standard approach have thus resisted the implementation of the most prominent development in ethical theory in recent history: that of particularism. In this article, I argue that particularist thinking has much to offer to business ethics and that standard resistance to particularist business ethics is based largely on misunderstandings. I do so by illustrating how the harbinger of particularism, W. D. Ross, countenances the practical wisdom of particularist ethics while being 1) invulnerable to standard objections to particularist business ethics and 2) compatible with the generalism of the standard approach. The Rossian business ethic is therefore one that the standard approach should be eager to include.
There is some evidence that anti-inflammatory treatment may have beneficial effects in schizophrenia and major depression. Statins are cholesterol-lowering agents but have been found to be anti-inflammatory and also decrease C-reactive protein (CRP). Ondansetron is a serotonin (5-HT3) receptor antagonist widely used to prevent nausea and vomiting in patients receiving chemotherapy for cancer. Small studies have suggested that adjunctive Ondansetron is efficacious against schizophrenia symptoms. We carried out a feasibility study in schizophrenia patients (within 5 years of first diagnosis) to explore the adjunctive use of simvastatin and ondansetron on positive, negative and general psychopathology.
Methods
This was a 12 week rater blind placebo controlled study. All to gather 36 patients with DSM-IV diagnosis of schizophrenia were recruited, 12 in each arm. Patients were assessed at baseline and at 12 weeks using PANSS, CGI, GAF and AIMS.
Results
Both simvastatin and ondansetron provide some evidence of a reduction in symptoms compared to treatment as usual (TAU) on PANSS total score, although, this was not statistically significant. In the secondary analyses, no significant differences were seen on CGI, GAF and AIMS.
Conclusions
Anti-inflammatory treatments have shown to have some beneficial effects in schizophrenia. Both simvastatin and ondansetron provide some evidence of a reduction in symptoms compared to treatment as usual. This study has led to a larger SMRI-funded, double blind, randomized control trial.
Immune mechanisms have been implicated in the pathogenesis of schizophrenia. This has lead to clinical trials of re-purposing drugs with off-target anti-inflammatory actions. They include the antibiotic minocycline and simvastatin (HMP-Co reductase inhibitor), which decrease microglial activation, and ondansetron a 5-HT3-receptor antagonist that has limited effects on cytokine production. This presentation will address their efficacy and mechanism of action.
Aims
1) Update on trials with minocycline including our own positive finding on negative symptoms (PMID: 16959472)
2) Present new results with ondansetron and simvastatin summarised below.
Methods
Ondansetron (8mg) and simvastatin (40mg) vs placebos in 2x2 design (PMID: 23782463). Patients aged 18-65, stable treatment, DSM IV schizophrenia-related diagnosis. PANSS and cognition at 0,3,6 months.
Results
The four cells of the 2x2 design contained 302 patients. The interaction between ondansetron and simvastatin was significant at p=.006 reflecting the lower scores in the 3 active treatment groups than in the P+P group. Ondansetron improved verbal (p=.007) and visual list learning (p=.02) with no other treatment effects on cognition.
Conclusions
Minocycline appears to benefit negative symptoms in early psychosis with a minor effect on cognition. Simvastatin had limited effects in our patients with established schizophrenia but its anti-inflammatory effects could be worth investigating in early psychosis. Ondansetron has a significant effect on new learning, which might be expected from its 5-HT3 antagonist properties. This may underlie a benefit on negative symptoms reported by others and us.
Cognitive impairment in schizophrenia is a strong predictor of the functional outcome and no effective treatments are available. MATRICS Consensus Cognitive Battery (MCCB) is approved by the FDA as outcome measure for trials of cognitive-enhancing drugs in schizophrenia. CogState Schizophrenia Battery (CSB) provides a briefer cognition assessment with minimal practice effects and a strong correlation between the CSB and MCCB composite scores. We tested the sensitivity of CSB as a cognitive outcome measure in a clinical trial in schizophrenia, where a cognitive-enhancing drug and cognitive training were combined.
Methods
49 participants with schizophrenia were enrolled in a double-blind, placebo-controlled study. Participants were randomised to modafinil (200mg/day) or placebo and underwent a cognitive training program for 10 weekdays. CSB was administered twice at baseline to minimise practice effects, at the last day of the intervention and two weeks after the completion of the intervention.
Results
There was a significant time effect at the end of the intervention on the CSB composite score (p=0.042). There was no significant treatment effect on CSB composite score at the end of the intervention (p=0.686) or at follow up (p=0.120).
Conclusions
Multiple administrations of CSB were well tolerated by participants. The significant time effects on the composite score may suggest the operation of practice effects. Several factors could have contributed to the lack of treatment effects on CSB, such as the burden of multiple neuropsychological testing in a relatively brief study, the duration of modafinil treatment and also the intensive nature of cognitive training.
