Impact of the COVID-19 pandemic on commencement of psychotropic medications in Northern Ireland: a population-wide, administrative data linkage study.

Objectives This study aimed to explore changes in commencement of psychotropic medications in first 20 months of the pandemic and associated restrictions in Northern Ireland (NI). Approach Antidepressant, anxiolytic, hypnotic and antipsychotic medications dispensed in all community pharmacies in NI (Jan-2012 to Oct-2021, Enhanced Prescribing Database) were linked to sociodemographic data (National Health Application and Infrastructure Services) for everyone alive and resident in NI aged ≥10years. Commencement of new medication was identified on a rolling monthly basis as a dispensation in a given month but not in the previous 24 months. Auto Regressive Integrated Moving Average (ARIMA) models were trained taking trends and seasonal effects into consideration. Monthly forecasts were compared to actual numbers, at population level and within sociodemographic groups (gender, age, rurality, living-alone, deprivation). Results There were consistent increased numbers of individuals commencing antipsychotic medications in the group aged ≥65years, with observed to expected ratio ranging from 1.12 to 2.1.  Commencement of hypnotics was decreased throughout the study in individuals aged <18years (OER ranged from 0.28 to 0.70) but remained as expected for other sociodemographic groups.  Across all sociodemographic groups, commencement of antidepressants decreased initially (Mar-May 2020 population-level OER ranged from 0.61 to 0.79) and in Jan 2021 (population-level OER 0.78) corresponding with stricter stay at home restrictions but resumed the expected trend outside of these periods.  There were no obvious deviations from expected trends in commencement of anxiolytics. Conclusion There was a clear impact on older people with regards commencement of antipsychotic medications throughout the pandemic. Hypnotic commencement in children was lower than expected throughout the pandemic, which may reflect reduced need or reduced access to specialist paediatric services.

Sleep Medication Use by people with Cerebral Palsy: A Population Level DataLinkage Study

Objectives To (1) compare proportions of the population dispensed sleep medication, and rate (dispensations/month) and amount (milligrams/month) of dispensed sleep medication, in individuals with and without cerebral palsy (CP); and (2) describe dispensation of sleep medication within CP and non-CP cohorts with respect to sociodemographic and clinical characteristics. Approach Individuals aged 6 -36 years (aligning with those known to the Northern Ireland CP Register [NICPR]), registered with a general practitioner at 01-January-2018, were identified within the National Health Application and Infrastructure System.  Sleep medications dispensed 01-January-2018 to 31-December-2019 were extracted from the Enhanced Prescribing Database.  Analysis was limited to melatonin due to small counts in other medications.  Routine healthcare data was sourced from the Honest Broker Service (HBS).  NICPR clinical data (CP-type, Gross Motor Function Classification System (GMFCS), gestation and birthweight) were linked to routine healthcare data using the Health and Care Number by HBS. Descriptive statistics are presented. Results Complete matching was achieved between NICPR and healthcare data using the HCN.  Final cohorts consisted of 1,598 individuals with CP and 790,097 without CP. A greater proportion of those with CP were dispensed melatonin compared to those without CP (4.6% vs 1.0%).  The CP cohort were also dispensed melatonin at a greater rate (median(IQR) CP 0.33(0.71) vs non-CP 0.25(0.54) dispensations/month) and in greater amounts (median(IQR) CP 30(74.7) vs non-CP 17.5(55.0) mg/month).  Within the CP cohort, differences in melatonin dispensation were observed across sociodemographic groups (male 5.1% vs female 3.9%; children 8.2% vs young adults 2.2%; urban 6.5% vs rural 5.0%); deprived 5.1% vs affluent 4.2%).  Clinical characteristics associated with greatest dispensation of melatonin were non-spastic CP (6.83%), GMFCS IV&V (5.29%), or extremely premature birth (6.85%). Conclusion Individuals with CP, particularly children, are more likely to be dispensed sleep medications compared to the general population.  Awareness of this disparity could encourage further research on assessment and management of sleep in CP and facilitate discussions between healthcare providers and families on underlying causes of sleep problems

Analyses of ionizing radiation effects in – vitro in peripheral blood 1 lymphocytes with Raman spectroscopy

The use of Raman spectroscopy to measure the biochemical profile of healthy and diseased cells and tissues may be a potential solution to many diagnostic problems in the clinic. Although extensively used to identify changes in the biochemical profiles of cancerous cells and tissue, Raman spectroscopy has been used less often for analyzing changes to the cellular environment by external factors such as ionizing radiation. In tandem with this, the biological impact of low doses of ionizing radiation remains poorly understood. Extensive studies have been performed on the radiobiological effects associated with radiation doses above 0.1 Gy, and are well characterized, but recent studies on low-dose radiation exposure have revealed complex and highly variable responses. We report here the novel finding that demonstrate the capability of Raman spectroscopy to detect radiation-induced damage responses in isolated lymphocytes irradiated with doses of 0.05 and 0.5 Gy. Lymphocytes were isolated from peripheral blood in a cohort of volunteers, cultured ex vivo and then irradiated. Within 1 h after irradiation spectral effects were observed with Raman microspectroscopy and principal component analysis and linear discriminant analysis at both doses relative to the sham-irradiated control (0 Gy). Cellular DNA damage was confirmed using parallel γ-H2AX fluorescence measurements on the extracted lymphocytes per donor and per dose. DNA damage measurements exhibited interindividual variability among both donors and dose, which matched that seen in the spectral variability in the lymphocyte cohort. Further evidence of links between spectral features and DNA damage was also observed, which may potentially allow noninvasive insight into the DNA remodeling that occurs after exposure to ionizing radiation

Changing trends in child welfare inequalities in Northern Ireland

Objectives This study uses longitudinal administrative data to investigate the relationship between area level deprivation and the 1) referral, 2) investigation, 3) registration and 4) looked-after stages of children’s contact with child and family social work in Northern Ireland (NI) from 2010-2017 (stages 1-3) and 2010-2020 (stage 4). Methods Children’s social care data (SOSCARE database) for the years 2010 to 2020 were obtained from the Honest Broker Service in NI. The data were linked with the 2017 NI Multiple Deprivation Measure through the family of origin postcode. Cross-tabulations of year and deprivation decile were used to produce frequencies of children who experienced the four levels of intervention within each of the study years. These were then used to calculate various measures of absolute and relative inequality including the Slope Index of Inequality (SII), the Relative Ratio of Inequality (RRI) and the Relative Index of Inequality (RII). Results There was a clear and increasing social gradient in child welfare interventions over time. Children referred to children’s social care during 2010-2017 were 4-5 times more likely to come from the most deprived areas compared to the least deprived. Despite fairly stable levels of referral inequality, the ratio of children subject to child protection investigations rose from 3 in 2010 to 6 in 2017, the ratio of children subject to child protection plans rose from 4.5 in 2010 to 8 in 2017 and the ratio of children looked after rose from 4 in 2010 to 9 in 2020. This widening inequality was largely driven by the increasing involvement of younger children from the most deprived areas in child protection and looked-after processes. Conclusion In an environment of economic austerity and reduced spending, we are intervening in the lives of children and families living in the most deprived areas of NI at disproportionate rates. The current independent review of children’s social care offers an opportunity to reconfigure current provision with a clear inequalities focus

A bridge from uncertainty to understanding : the meaning of symptom management digital health technology during cancer treatment

Objective: Digital health technology is valued as a tool to provide person-centred care and improve health outcomes amongst people with cancer and their family caregivers. Although the evidence to date shows encouraging effectiveness, there is limited knowledge regarding the lived experience and personal meaning of using supportive technology during cancer treatment. The aim of this study was to explore the lived experiences of people with colorectal cancer receiving chemotherapy using digital health symptom management technology and their family caregivers. Methods: A longitudinal and multi-perspective interpretative phenomenological analytical approach was adopted including three people with newly diagnosed colorectal cancer and four family caregivers. Findings: Three superordinate themes and related subthemes were identified. The first theme (The 3 Cs of symptom management technology) centred on the continuity of care that participants felt while using the technology. The second theme (Digital health technology as a psychosocial support) offered insights into the psychological benefits using technology incurred as they navigated their cancer diagnosis including sense of control and psychological safety. The final theme (Impact of digital health technology on family caregivers) details the supportive effect the technology had on family caregivers’ role, responsibilities and well-being during the cancer experience. Conclusion: Digital health technology can act as a bridge from uncertainty to an understanding regarding a cancer diagnosis and its treatment. Digital health technology can support peoples' understanding of cancer and enhance self-management practices, while being a psychological support in navigating the uncertain and often worrying period of receiving cancer treatment

Effects of acute and repeated treatment with methocinnamox, a mu opioid receptor antagonist, on fentanyl self-administration in rhesus monkeys

Methocinnamox (MCAM), a mu opioid receptor antagonist with a long duration of action, attenuates heroin self-administration in rhesus monkeys, suggesting it could be an effective treatment for opioid use disorder (OUD). This study examined effects of acute and repeated MCAM administration on self-administration of the high-efficacy mu opioid receptor agonist fentanyl and characterized MCAM pharmacokinetics. Four rhesus monkeys self-administered i.v. infusions of fentanyl (0.00032 mg/kg/infusion) or cocaine (0.032 mg/kg/infusion). MCAM (0.1–0.32 mg/kg) or the opioid receptor antagonist naltrexone (0.001–0.032 mg/kg) was injected prior to test sessions to evaluate acute effects. On a separate occasion, 0.32 mg/kg MCAM was injected every 12 days for 5 total injections to evaluate the effectiveness of repeated treatment. Following acute injection, MCAM and naltrexone decreased fentanyl self-administration on the day of treatment, with attenuation lasting for up to 2 weeks after the larger MCAM dose and <1 day after naltrexone. Repeated MCAM administration decreased fentanyl self-administration for more than 2 months without altering cocaine self-administration. MCAM plasma concentrations peaked 15–45 min after injection, with a half-life ranging from 13.7 to 199.8 min, and decreased markedly 1 day after injection. MCAM selectively reduced opioid self-administration and remained effective with repeated administration. Moreover, MCAM was effective at times when plasma levels were very low, suggesting that pharmacodynamic (i.e., pseudoirreversible binding to mu opioid receptors) and not pharmacokinetic factors play a significant role in its long-lasting effects. Taken together with previous studies, these data indicate that MCAM could be a safe, effective, and long-acting treatment for OUD

JACK trial protocol: a phase III multicentre cluster randomised controlled trial of a school-based relationship and sexuality education intervention focusing on young male perspectives.

INTRODUCTION: Teenage pregnancy remains a worldwide health concern which is an outcome of, and contributor to, health inequalities. The need for gender-aware interventions with a focus on males in addressing teenage pregnancy has been highlighted as a global health need by WHO and identified in systematic reviews of (relationship and sexuality education (RSE)). This study aims to test the effectiveness of an interactive film-based RSE intervention, which draws explicit attention to the role of males in preventing an unintended pregnancy by reducing unprotected heterosexual teenage sex among males and females under age 16 years. METHODS AND ANALYSIS: A phase III cluster randomised trial with embedded process and economic evaluations. If I Were Jack encompasses a culturally sensitive interactive film, classroom materials, a teacher-trainer session and parent animations and will be delivered to replace some of the usual RSE for the target age group in schools in the intervention group. Schools in the control group will not receive the intervention and will continue with usual RSE. Participants will not be blinded to allocation. Schools are the unit of randomisation stratified per country and socioeconomic status. We aim to recruit 66 UK schools (24 in Northern Ireland; 14 in each of England, Scotland and Wales), including approximately 7900 pupils. A questionnaire will be administered at baseline and at 12-14 months postintervention. The primary outcome is reported unprotected sex, a surrogate measure associated with unintended teenage pregnancy. Secondary outcomes include knowledge, attitudes, skills and intentions relating to avoiding teenage pregnancy in addition to frequency of engagement in sexual intercourse, contraception use and diagnosis of sexually transmitted infections. ETHICS AND DISSEMINATION: Ethical approval was obtained from Queen's University Belfast. Results will be published in peer-reviewed journals and disseminated to stakeholders. Funding is from the National Institute for Health Research. TRIAL REGISTRATION NUMBER: ISRCTN99459996
