Adolescence and young adulthood are sensitive developmental periods to environmental influences. Investigating pre-emptive measures against stressors, such as those associated with the COVID-19 pandemic, on mental health is crucial. We aimed to synthesize evidence on pre-pandemic resilience factors shaping youth mental health outcomes during this period. For this pre-registered systematic review, we searched seven databases for longitudinal studies of youth populations affected by the COVID-19 pandemic, assessing a priori defined resilience factors at the individual, family, or community level before the pandemic. Studies required validated mental health or wellbeing measures collected both before and during the pandemic. Study quality was assessed using the corresponding NIH Quality Assessment Tool. From 4,419 unique records, 32 studies across 12 countries were included, using 46 distinct resilience measures. Due to the heterogeneity of study designs, we applied a narrative synthesis approach, finding that resilience factors were generally associated with better mental health outcomes both prior to and during the pandemic. However, most factors did not mitigate pandemic-related mental health effects. Nonetheless, family-level resilience factors emerged as promising under specific conditions. Study quality was generally fair, with concerns in resilience assessment and sampling quality. Future research should prioritize rigorous study designs and comprehensive resilience assessments.
Catherine Peters discusses how writers such as the Cuban poet Juan Francisco Manzano reworked the Romantic trope of the revolutionary “common wind” to forge kinship networks among forcibly displaced peoples. In formulating this argument, Peters shifts the conventional focus on the French Revolution as the hub of radical Romantic thought to the Haitian Revolution, where “fraternité” refers not to an abstract ideal but a very real desire to reconstitute those family relations disrupted by the institution of slavery.
The increased global prevalence of type II diabetes mellitus (T2DM) is associated with consumption of low fibre ‘Western diets’. Characteristic metabolic parameters of these individuals include insulin resistance, high fasting and postprandial glucose, as well as low-grade systemic inflammation. Gut microbiota composition is altered significantly in these cohorts suggesting a causative link between diet, microbiota and disease. Dietary fibre consumption has been shown to alleviate these changes and improve glucose parameters in individuals with metabolic disease. We previously reported that yeast β-glucan (yeast beta-1,3/1,6-D-glucan; Wellmune) supplementation ameliorated hyperinsulinaemia and insulin resistance in a murine model. Here, we conducted a randomised, placebo-controlled, two-armed dietary fibre phase I exploratory intervention study in patients with T2DM. The primary outcome measure was alteration to microbiota composition, while the secondary outcome measures included markers of glycaemic control, inflammation as well as metabolomics. Patients were supplemented with 2·5g/day of maltodextrin (placebo) or yeast β-1,3/1,6-D-glucan (treatment). Yeast β-glucan (Wellmune) lowered insulin resistance compared with the placebo maltodextrin after 8 weeks of consumption. TNFα was significantly lower after 4 weeks of β-glucan supplementation. Significantly higher fecal concentrations of several bile acids were detected in the treatment group when compared with the placebo after 8 weeks. These included tauroursodeoxycholic acid, which was previously shown to improve glucose control and lower insulin resistance. Interestingly, the hypoglycaemic and anti-inflammatory effect of yeast β-glucan was independent of any changes in fecal microbiota composition or short-chain fatty acid levels. Our findings highlight the potential of yeast β-glucan to lower insulin resistance in patients with T2DM.
Accurately and comprehensively assessing physical health risk for people with intellectual disability (ID) is paramount in improving health outcomes, reducing the need for acute hospital admissions and preventing mortality. We aimed to compare the existing approach to assessing physical health risk with the use of a novel standardised risk stratification tool, the Decision Support Tool for Physical Health [DST-PH]. We hypothesise that DST-PH will be useful in improving and streamlining the assessment of physical health risk factors in people with ID.
People with ID are more likely to have poorer physical health outcomes and are at increased risk of premature and preventable death. Annual data from LeDeR (Learning from lives and deaths – People with a learning disability and autistic people) consistently underlines the need for developing strategies that reduce the risk of people with ID developing conditions associated with high causes of morbidity and mortality.
The DST-PH is an online tool that helps clinicians to identify people with ID who are at increased risk of early and preventable death. The tool captures key patient data about underlying health issues and risk factors that can contribute to poor health outcomes. Patients are then stratified according to their overall level of risk using a ‘RAG’ (red, green, amber) system. This allows targeted intervention and monitoring for those patients in need.
Methods
All patient-facing staff in the Wandsworth Learning Disability Service were surveyed about their confidence levels in assessing physical health risk factors independently. We then asked each member of staff to assess physical health risk and assign a RAG rating for 2 randomly selected patients using their usual methods (clinical judgement). We then assessed the same patients using the DST-PH tool. Results were then compared to determine the degree of correlation between clinicians' existing risk assessment methods and the risk ratings assigned using the DST-PH.
Results
Survey results showed that staff would welcome the introduction of a risk stratification tool. Comparison of risk assessment data showed a significant correlation between clinicians’ assessment and the results from the tool.
Conclusion
Results evidenced the drive for ID clinicians to be observant of the physical health care needs of their patients. Introduction of the DST-PH may help to streamline the risk assessment process and increase confidence levels of clinicians.
Long-term urinary catheters are problematic and burdensome for patients, carers and health services. Nursing practice to improve the management of long-term urinary catheters has been held back by a lack of evidence to support policy and practice. Little is known about who uses a catheter long term and the resources and costs needed for their management. Understanding these costs will help to target innovations to improve care. There have been no substantial innovations to urinary catheters or their management recently and no publications to characterise users and costs.
Aim:
To describe long-term catheter users and explore catheter-related service use and costs in England.
Methods:
Descriptive information on the characteristics of catheter users and their use of services was obtained from: General Practice records (n = 607), district nursing records (n = 303), questionnaires to patients (n = 333) and triangulated, 2009–2012. Annual service costs (British pounds 2011) were computed.
Findings:
Most catheter users (59.6%) were men, nearly three-quarters (71.2%) were over 70 years and 60.8% used a urethral catheter. Women tended to be younger than men and more likely to use a suprapubic catheter. The services used most frequently over 12 months were general practitioner (by 63.1%) and out of hours services (43.0%); 15.5% accessed Accident and Emergency services for urgent catheter-related care. Hospital use accounted for nearly half (48.9%) of total health service costs (mainly due to inpatient stays by 13.6% of participants); catheter supplies/medications were next most costly (25.7%). Half of all costs were accounted for by 14.2% of users. The median annual cost of services used was £6.38, IQR: £344–£1324; district nursing services added approximately a further £200 per annum.
Conclusions:
Finding better ways to reduce catheter problems (e.g. blockage, infection) that cause unplanned visits, urgent or hospital care should be a priority to improve quality of life for long-term catheter users and reduce health service expenditure.
People with schizophrenia (PSZ) are impaired in attentional prioritization of non-salient but relevant stimuli over salient distractors during visual working memory (VWM) encoding. Conversely, guidance of top–down attention by external predictive cues is intact. Yet, it is unknown whether this preserved ability can help PSZ encode more information in the presence of salient distractors.
Methods
We employed a visuospatial change-detection task using four Gabor patches with differing orientations in 66 PSZ and 74 healthy controls (HCS). Two Gabor patches flickered which were designated either as targets or distractors and either a predictive or a non-predictive cue was displayed to manipulate top–down attention, resulting in four conditions.
Results
We observed significant effects of group, salience and cue as well as significant interactions of salience by cue, group by salience and group by cue. Across all conditions, PSZ stored significantly less information in VWM than HCS. PSZ stored significantly less non-flickering than flickering information with a non-predictive cue. However, PSZ stored significantly more flickering and non-flickering information with a predictive cue.
Conclusions
Our findings indicate that control of attentional selection is impaired in schizophrenia. We demonstrate that additional top–down information significantly improves performance in PSZ. The observed deficit in attentional control suggests a disturbance of GABAergic inhibition in early visual areas. Moreover, our findings are indicative of a mechanism for enhancing attentional control in PSZ, which could be utilized by pro-cognitive interventions. Thus, the current paradigm is suitable to reveal both preserved and compromised cognitive component processes in schizophrenia.
The majority of studies on ‘faith’ (fides) in the thought of Thomas Aquinas consider it in a religious or theological context: fides as the theological virtue by which one assents to the truths of divine revelation. The focus on theological faith is appropriate, given its central importance as a theological virtue, but this is not the only sense of fides that Thomas identifies. The present study investigates two non-theological senses formulated in his commentary on the De Trinitate of Boethius: first, fides as the proximate cause of assenting to principles within a given science (‘epistemic faith’) and, second, fides as an indispensable element of society (‘societal faith’). These senses have been largely overlooked in secondary literature but, I argue, might help to dispel mischaracterizations of faith as fundamentally unreasonable.
Hospitals play a significant and important role in funding high-cost medicines so patients can access treatments they need. High-cost medicines are often specialty medicines, which contribute to a significant and increasing portion of the hospital budget. It is imperative that these expensive medicines are governed and managed with a fair, standardized evidence-based process. We aim to provide a framework for Drugs and Therapeutics Committees (DTCs).
Methods
During 2021, Guiding Principles were developed following a literature review and survey of current practices by DTCs in Australia. An Expert Advisory Group (EAG) was convened, comprising individuals with expertise in quality use of medicines, evidence-based medicine and medicines governance. The guiding principles were drafted by the EAG, in consultation with a range of stakeholders and relevant external organizations. All feedback was collated, reviewed and discussed to refine the content of the final Guiding Principles released in January 2022.
Results
Seven overarching principles provide key recommendations for the governance of high-cost medicines:
(i) A definition of high‑cost medicines should be determined and clearly articulated for use by each medicines governance committee.
(ii) Review of high-cost medicines requires members with relevant expertize to facilitate good and effective decision-making.
(iii) The committee should engage directly with the applicant prior to review to ensure a full understanding of the rationale for the request.
(iv) consistent, robust and transparent procedure for the assessment of high-cost medicine applications should be defined and implemented for use by each medicines governance committee to ensure fair process.
(v) Ethical considerations fundamentally underpin deliberations around high-cost medicines.
(vi) The decisions and outcomes of the decision making should be transparent and appropriately communicated to the various audiences.
(vii) The high-quality assessment of high-cost medicines requires appropriate training and resourcing.
Conclusions
These national Guiding Principles promote consistent, evidence-based use of high-cost medicines and provide a framework for DTCs to assess and achieve effective governance for the quality use of high‑cost medicines.
As the configuration of global environmental governance has become more complex over the past fifty years, numerous scholars have underscored the importance of understanding the transnational networks of public, private, and nonprofit organizations that comprise it. Collaborative Event Ethnography (CEE) is a relational methodology that aims to capture the dynamics of these constantly shifting networks. CEE draws on multisited, team, and institutional ethnography to assemble teams of researchers to study major international conferences, which offer important political spaces where these networks can be observed. Drawing on more than ten years of experience with CEE, we argue that strong approaches to collaboration offer rich opportunities for analyses of global environmental governance. In CEE, researchers collaborate on all aspects of the research process, from research design to analysis to writing. The aim of this chapter is to introduce CEE, providing a history of its development, reviewing the benefits and challenges of CEE, reflecting on the theoretical insights generated through CEE in relation to understanding environmental agreement-making, and offering practical guidance for researchers interested in using the methodology. Going beyond CEE, the chapter also considers collaboration in the context of the broader scholarly landscape.
Four decades of war, political upheaval, economic deprivation and forced displacement have profoundly affected both in-country and refugee Afghan populations.
Aims
We reviewed literature on mental health and psychosocial well-being, to assess the current evidence and describe mental healthcare systems, including government programmes and community-based interventions.
Method
In 2022, we conducted a systematic search in Google Scholar, PTSDpubs, PubMed and PsycINFO, and a hand search of grey literature (N = 214 papers). We identified the main factors driving the epidemiology of mental health problems, culturally salient understandings of psychological distress, coping strategies and help-seeking behaviours, and interventions for mental health and psychosocial support.
Results
Mental health problems and psychological distress show higher risks for women, ethnic minorities, people with disabilities and youth. Issues of suicidality and drug use are emerging problems that are understudied. Afghans use specific vocabulary to convey psychological distress, drawing on culturally relevant concepts of body–mind relationships. Coping strategies are largely embedded in one's faith and family. Over the past two decades, concerted efforts were made to integrate mental health into the nation's healthcare system, train cadres of psychosocial counsellors, and develop community-based psychosocial initiatives with the help of non-governmental organisations. A small but growing body of research is emerging around psychological interventions adapted to Afghan contexts and culture.
Conclusions
We make four recommendations to promote health equity and sustainable systems of care. Interventions must build cultural relevance, invest in community-based psychosocial support and evidence-based psychological interventions, maintain core mental health services at logical points of access and foster integrated systems of care.
Observational studies suggest that 25-hydroxy vitamin D (25(OH)D) concentration is inversely associated with pain. However, findings from intervention trials are inconsistent. We assessed the effect of vitamin D supplementation on pain using data from a large, double-blind, population-based, placebo-controlled trial (the D-Health Trial). 21 315 participants (aged 60–84 years) were randomly assigned to a monthly dose of 60 000 IU vitamin D3 or matching placebo. Pain was measured using the six-item Pain Impact Questionnaire (PIQ-6), administered 1, 2 and 5 years after enrolment. We used regression models (linear for continuous PIQ-6 score and log-binomial for binary categorisations of the score, namely ‘some or more pain impact’ and ‘presence of any bodily pain’) to estimate the effect of vitamin D on pain. We included 20 423 participants who completed ≥1 PIQ-6. In blood samples collected from 3943 randomly selected participants (∼800 per year), the mean (sd) 25(OH)D concentrations were 77 (sd 25) and 115 (sd 30) nmol/l in the placebo and vitamin D groups, respectively. Most (76 %) participants were predicted to have 25(OH)D concentration >50 nmol/l at baseline. The mean PIQ-6 was similar in all surveys (∼50·4). The adjusted mean difference in PIQ-6 score (vitamin D cf placebo) was 0·02 (95 % CI (−0·20, 0·25)). The proportion of participants with some or more pain impact and with the presence of bodily pain was also similar between groups (both prevalence ratios 1·01, 95 % CI (0·99, 1·03)). In conclusion, supplementation with 60 000 IU of vitamin D3/month had negligible effect on bodily pain.
We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from the climate–health nexus, climate (im)mobility and security, sustainable practices for land use and finance, losses and damages, inclusive societal climate decisions and ways to overcome structural barriers to accelerate mitigation and limit global warming to below 2°C.
Technical summary
We synthesize 10 topics within climate research where there have been significant advances or emerging scientific consensus since January 2021. The selection of these insights was based on input from an international open call with broad disciplinary scope. Findings concern: (1) new aspects of soft and hard limits to adaptation; (2) the emergence of regional vulnerability hotspots from climate impacts and human vulnerability; (3) new threats on the climate–health horizon – some involving plants and animals; (4) climate (im)mobility and the need for anticipatory action; (5) security and climate; (6) sustainable land management as a prerequisite to land-based solutions; (7) sustainable finance practices in the private sector and the need for political guidance; (8) the urgent planetary imperative for addressing losses and damages; (9) inclusive societal choices for climate-resilient development and (10) how to overcome barriers to accelerate mitigation and limit global warming to below 2°C.
Social media summary
Science has evidence on barriers to mitigation and how to overcome them to avoid limits to adaptation across multiple fields.
Experiences of child abuse and neglect are risk factors for youth suicidal thoughts and behaviors. Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.
Based on the largest independent UK study of person-centred support and written by an experienced team of authors, this book explores with service users, practitioners, carers and managers what person-centred support means to them, what barriers stand in the way and how these can be overcome.
In recent years, there has been a growing interest to enhance patients’ symptom management during routine cancer care using patient-reported outcome measures. The goal of this study is to analyse patients’ responses to the Edmonton Symptom Assessment System (ESAS) to determine whether patient-reported outcomes could help characterise those patients with the highest supportive care needs and symptom burden in order to help provide targeted support for patients.
Methods:
In this study, we analysed ESAS questionnaire responses completed by patients as part of their routine care and considered part of patients’ standard of care. Statistical analyses were performed using the IBM SPSS Statistics version 26.0. Descriptive statistics are used to summarise patient demographics, disease characteristics and patient-reported symptom severity and prevalence.
Results:
The overall mean age is 65.2 ± 12.8 years comprising 43.8% male and 56.2% female patients. The five common primary disease sites are breast (26.2%), haematology (21.1%), gastrointestinal (15.3%), genitourinary (12.7%) and lung (12.0%) cancers. The mean severity for each symptom is all mild (score: 1–3). The three most common reported symptoms causing distress are tiredness, poor overall wellbeing and anxiety, and the least reported symptom is nausea.
Conclusions:
Systematic self-reporting of patients’ symptoms is important to improve symptom management, timely facilitation of appropriate intervention, patient experience, and patient and family satisfaction. The awareness of disease site, gender and age-related symptom variations should help in the design and provision of appropriate symptom-directed, tumour-specific and patient-focused interventions to meet patients’ immediate needs.
Phylogenetic analyses can be used to resolve taxonomic uncertainties and reconstruct a species’ evolutionary history. This can be combined with ecological data to predict missing life history traits which are important for creation of conservation management strategies. We investigated the evolutionary and life history of the ‘Critically Endangered’ Grenada Dove Leptotila wellsi by estimating its phylogenetic placement and using this new phylogeny to test the accuracy of phylogenetic comparative methods for estimating both documented and unknown life history traits. We extracted DNA from two Grenada Dove samples and obtained sequences from three mitochondrial markers: Cytochrome oxidase I (COI), NADH dehydrogenase 2 (ND2) and Cytochrome b (Cyt b); and one nuclear marker: β-Fibrinogen intron 7 (β-FIB). We present the first genetic data obtained for the Grenada Dove. Our data identify the Grey-Chested Dove Leptotila cassinii as the species which shares both a most recent common ancestor, with an estimated divergence of approximately 2.53 million years ago, and the smallest genetic distance (P = 0.0303) with the Grenada Dove. Life history trait values for the Grenada Dove predicted from our analyses using phylogenetic imputation are: clutch size = 2 (± 0.09) eggs; clutches per year = 1.4 (± 0.81); incubation time = 14.2 (± 0.75) days; hatching weight = 3.8 g (± 1.05) and single imputation: fledging age (genus median) = 15.5 days, longevity (genus median) = 8.6 years. This study contributes novel information regarding evolutionary history and life history characteristics to inform long-term conservation actions for a ‘Critically Endangered’ species.
To examine the costs and cost-effectiveness of mirtazapine compared to placebo over 12-week follow-up.
Design:
Economic evaluation in a double-blind randomized controlled trial of mirtazapine vs. placebo.
Setting:
Community settings and care homes in 26 UK centers.
Participants:
People with probable or possible Alzheimer’s disease and agitation.
Measurements:
Primary outcome included incremental cost of participants’ health and social care per 6-point difference in CMAI score at 12 weeks. Secondary cost-utility analyses examined participants’ and unpaid carers’ gain in quality-adjusted life years (derived from EQ-5D-5L, DEMQOL-Proxy-U, and DEMQOL-U) from the health and social care and societal perspectives.
Results:
One hundred and two participants were allocated to each group; 81 mirtazapine and 90 placebo participants completed a 12-week assessment (87 and 95, respectively, completed a 6-week assessment). Mirtazapine and placebo groups did not differ on mean CMAI scores or health and social care costs over the study period, before or after adjustment for center and living arrangement (independent living/care home). On the primary outcome, neither mirtazapine nor placebo could be considered a cost-effective strategy with a high level of confidence. Groups did not differ in terms of participant self- or proxy-rated or carer self-rated quality of life scores, health and social care or societal costs, before or after adjustment.
Conclusions:
On cost-effectiveness grounds, the use of mirtazapine cannot be recommended for agitated behaviors in people living with dementia. Effective and cost-effective medications for agitation in dementia remain to be identified in cases where non-pharmacological strategies for managing agitation have been unsuccessful.
Policy measures to slow the spread of coronavirus disease 2019 (COVID-19), such as curfews and business closures, may have negative effects on mental health. Populations in low- and middle-income countries (LMICs) may be particularly affected due to high rates of poverty and less comprehensive welfare systems, but the evidence is scarce. We evaluated predictors of depression, anxiety, and psychological distress in Uganda, which implemented one of the world's most stringent lockdowns.
Methods
We conducted a mobile phone-based cross-sectional survey from December 2020 through April 2021 among individuals aged 18 years or over in Uganda. We measured depression, anxiety, and psychological distress using the Patient Health Questionnaire (PHQ)-2, the Generalized Anxiety Disorder (GAD)-2, and the PHQ-4. We applied linear regression to assess associations between experiences of COVID-19 (including fear of infection, social isolation, income loss, difficulty accessing medical care, school closings, and interactions with police) and PHQ-4 score, adjusted for sociodemographic characteristics.
Results
29.2% of 4066 total participants reported scores indicating moderate psychological distress, and 12.1% reported scores indicating severe distress. Distress was most common among individuals who were female, had lower levels of education, and lived in households with children. Related to COVID-19, PHQ-4 score was significantly associated with difficulty accessing medical care, worries about COVID-19, worries about interactions with police over lockdown measures, and days spent at home.
Conclusions
There is an urgent need to address the significant burden of psychological distress associated with COVID-19 and policy responses in LMICs. Pandemic mitigation strategies must consider mental health consequences.
This audit aimed to assess the adherence to the anti-psychotic policy for delirium in the medical wards. It aimed to assess compliance with each of the guidelines mentioned in the health board's policy which is based on the National Institute for Health and Cares Excellence (NICE) guidelines.
Methods
After registering the audit, the Acute medical ward was approached for the hospital numbers of all the patients admitted in the months between January and March 2021, and 70 case records were screened. Case notes of patients above 18 years who were diagnosed with delirium including those after managing alcohol withdrawal were included. Those who were admitted only with alcohol withdrawal delirium were excluded. 47 case records were selected for data collection. A proforma was prepared based on the policy available in the intranet and data were entered.
Results
Retrospective data of 47 patients who had delirium were analysed which included 18 males and 29 females. The mean age of the participants was 80.7 years (range 40–101; SD + 30). The mean days of referral after admission were 28(+7.07). 34%were diagnosed to have delirium by the treating team,8.5% were diagnosed by the Emergency Department (ED) team and 57.4% were diagnosed by the liaison psychiatric team. 57% had another psychiatric diagnosis. The cause for delirium was mentioned in 55% of the records and the most common cause was urinary tract infection (31%) followed by multifactorial delirium (27%). Antipsychotics were prescribed for 57% and among those who received 74% received risperidone, 15% received olanzapine, and 11% haloperidol. Compliance was 100% in prescribing appropriate antipsychotics, maximum dose, investigations (expect x-ray chest and CT scan), only 54% compliance was observed with regards to stopping the antipsychotic before discharge and in 23% it was mentioned to be monitored by the GP and another 23% by the treating team.
Conclusion
This audit has displayed the lacuna in the prescription of antipsychotics for patients diagnosed with delirium. Periodic programs will be planned and executed for training the liaison practitioners and the staff in the medical wards regarding the diagnosis and management of delirium especially the prescription of antipsychotics. A re-audit will be conducted after 6 months.
