    BACKGROUND: People with severe mental health conditions, such as schizophrenia, and their family caregivers are underserved in low- and middle-income countries where structured psychosocial support in the community is often lacking. This can present challenges to recovery and for coping with additional strains, such as a pandemic.AIM: This study explored the experiences and coping strategies of people with lived experience of a severe mental health condition, and family caregivers, in South Africa during the initial stages of the coronavirus disease 2019 (COVID-19) pandemic.SETTING: This qualitative study was conducted in the Nelson Mandela Bay District, Eastern Cape, South Africa, in the most restrictive period of the COVID-19 lockdown.METHODS: Telephonic qualitative interviews were conducted with people with lived experience ( n = 14) and caregivers ( n = 15). Audio recordings were transcribed and translated to English from isiXhosa. Thematic analysis was conducted with NVivo 12. RESULTS: Participants described negative impacts including increased material hardship, intensified social isolation and heightened anxiety, particularly among caregivers who had multiple caregiving responsibilities. Coping strategies included finding ways to not only get support from others but also give support, engaging in productive activities and taking care of physical health. The main limitation was inclusion only of people with access to a telephone.CONCLUSION: Support needs for people with severe mental health conditions and their families should include opportunities for social interaction and sharing coping strategies as well as bolstering financial security.CONTRIBUTION: These findings indicate that current support for this vulnerable group is inadequate, and resource allocation for implementation of additional community-based, recovery-focused services for families must be prioritised.</p

    Peer-led recovery groups for people with psychosis in South Africa (PRIZE):protocol for a randomised controlled feasibility trial

    Background: The available care for people with psychosis in South Africa is inadequate to support personal recovery. Group peer support interventions are a promising approach to foster recovery, but little is known about the preferences of service users, or the practical application of this care model, in low- and middle-income countries (LMIC). This study aims to assess the acceptability and feasibility of integrating peer-led recovery groups for people with psychosis and their caregivers in South Africa into existing systems of care, and to determine key parameters in preparation for a definitive trial. Methods: The study is set in Nelson Mandela Bay Metropolitan district of the Eastern Cape Province, South Africa. The design is an individually randomised parallel group feasibility trial comparing recovery groups in addition to treatment as usual (TAU) with TAU alone in a 1:1 allocation ratio. We aim to recruit 100 isiXhosa-speaking people with psychosis and 100 linked caregivers. TAU comprises anti-psychotic medication-focused outpatient care. The intervention arm will comprise seven recovery groups, including service users and caregiver participants. Recovery groups will be delivered in two phases: a 2-month phase facilitated by an auxiliary social worker, then a 3-month peer-led phase. We will use mixed methods to evaluate the process and outcomes of the study. Intervention acceptability and feasibility (primary outcomes) will be assessed at 5 months post-intervention start using qualitative data collected from service users, caregivers, and auxiliary social workers, along with quantitative process indicators. Facilitator competence will be assessed with the GroupACT observational rating tool. Trial procedures will be assessed, including recruitment and retention rates, contamination, and validity of quantitative outcome measures. To explore potential effectiveness, quantitative outcome data (functioning, unmet needs, personal recovery, internalised stigma, health service use, medication adherence, and caregiver burden) will be collected at baseline, 2 months, and 5 months post-intervention start. Discussion: This study will contribute to the sparse evidence on the acceptability and feasibility of peer-led and recovery-oriented interventions for people with psychosis in LMIC when integrated into existing care systems. Results from this feasibility trial will inform preparations for a definitive trial and subsequent larger-scale implementation.

    Significant reductions in human visual gamma frequency by the gaba reuptake inhibitor tiagabine revealed by robust peak frequency estimation

    Get PDF
    The frequency of visual gamma oscillations is determined by both the neuronal excitation-inhibition balance and the time constants of GABAergic processes. The gamma peak frequency has been linked to sensory processing, cognitive function, cortical structure, and may have a genetic contribution. To disentangle the intricate relationship among these factors, accurate and reliable estimates of peak frequency are required. Here, a bootstrapping approach that provides estimates of peak frequency reliability, thereby increasing the robustness of the inferences made on this parameter was developed. The method using both simulated data and real data from two previous pharmacological MEG studies of visual gamma with alcohol and tiagabine was validated. In particular, the study by Muthukumaraswamy et al. [] (Neuropsychopharmacology 38(6):1105-1112), in which GABAergic enhancement by tiagabine had previously demonstrated a null effect on visual gamma oscillations, contrasting with strong evidence from both animal models and very recent human studies was re-evaluated. After improved peak frequency estimation and additional exclusion of unreliably measured data, it was found that the GABA reuptake inhibitor tiagabine did produce, as predicted, a marked decrease in visual gamma oscillation frequency. This result demonstrates the potential impact of objective approaches to data quality control, and provides additional translational evidence for the mechanisms of GABAergic transmission generating gamma oscillations in humans.

    Strategies for supporting the implementation of a task-shared psychological intervention in South Africa's chronic disease services: qualitative insights from health managers' experiences of project MIND

    BACKGROUND: Although evidence indicates that task-shared psychological interventions can reduce mental health treatment gaps in resource-constrained settings, systemic barriers have limited their widespread implementation. Evidence on how to sustain and scale such approaches is scant. This study responds to this gap by examining the experiences of South African health managers involved in the implementation of a task-shared counselling service for Project MIND. OBJECTIVES: To qualitatively describe managers' experiences of implementing the MIND programme and their insights into potential strategies for supporting sustained implementation. METHODS: Two focus group discussions (FGDs) and eight in-depth interviews (IDIs) were conducted with managers of urban and rural primary care facilities in the Western Cape province. All managers were female and 30-50 years old. FGDs and IDIs used an identical semi-structured topic guide to explore the experiences of the MIND programme and perceived barriers to sustained implementation. Normalisation process theory (NPT) guided the thematic analysis. RESULTS: Four themes emerged that mapped onto the NPT constructs. First, managers noted that their relational work with staff to promote support for the intervention and reduce resistance was key to facilitating implementation. Second, managers emphasised the need for staff reorientation and upskilling to foster openness to mental health practice and for adequate time for quality counselling. Third, managers underscored the importance of strengthening linkages between the health and social service sectors to facilitate delivery of comprehensive mental health services. Finally, managers recommended ongoing monitoring of the service and communication about its impacts as strategies for supporting integration into routine practice. CONCLUSIONS: Findings contribute to the emerging literature on strategies to support implementation of task-shared interventions in low- and middle-income countries. The findings highlight the leadership role of managers in identifying and actioning these strategies. Investing in managers' capacity to support implementation of psychological interventions is critical for scale-up of these mental health innovations

    Metabolomics demonstrates divergent responses of two Eucalyptus species to water stress

    Get PDF
    Past studies of water stress in Eucalyptus spp. generally highlighted the role of fewer than five “important” metabolites, whereas recent metabolomic studies on other genera have shown tens of compounds are affected. There are currently no metabolite profiling data for responses of stress-tolerant species to water stress. We used GC–MS metabolite profiling to examine the response of leaf metabolites to a long (2 month) and severe (Ψpredawn < −2 MPa) water stress in two species of the perennial tree genus Eucalyptus (the mesic Eucalyptus pauciflora and the semi-arid Eucalyptus dumosa). Polar metabolites in leaves were analysed by GC–MS and inorganic ions by capillary electrophoresis. Pressure–volume curves and metabolite measurements showed that water stress led to more negative osmotic potential and increased total osmotically active solutes in leaves of both species. Water stress affected around 30–40% of measured metabolites in E. dumosa and 10–15% in E. pauciflora. There were many metabolites that were affected in E. dumosa but not E. pauciflora, and some that had opposite responses in the two species. For example, in E. dumosa there were increases in five acyclic sugar alcohols and four low-abundance carbohydrates that were unaffected by water stress in E. pauciflora. Re-watering increased osmotic potential and decreased total osmotically active solutes in E. pauciflora, whereas in E. dumosa re-watering led to further decreases in osmotic potential and increases in total osmotically active solutes. This experiment has added several extra dimensions to previous targeted analyses of water stress responses in Eucalyptus, and highlights that even species that are closely related (e.g. congeners) may respond differently to water stress and re-waterin

    Risk of Parkinson's disease after tamoxifen treatment

    <p>Abstract</p> <p>Background</p> <p>Women have a reduced risk of developing Parkinson's disease (PD) compared with age-matched men. Neuro-protective effects of estrogen potentially explain this difference. Tamoxifen, commonly used in breast cancer treatment, may interfere with the protective effects of estrogen and increase risk of PD. We compared the rate of PD in Danish breast cancer patients treated with tamoxifen to the rate among those not treated with tamoxifen.</p> <p>Methods</p> <p>A cohort of 15,419 breast cancer patients identified from the Danish Breast Cancer Collaborative Group database was linked to the National Registry of Patients to identify PD diagnoses. Overall risk and rate of PD following identification into the study was compared between patients treated with tamoxifen as adjuvant hormonal therapy and patients not receiving tamoxifen. Time-dependent effects of tamoxifen treatment on PD rate were examined to estimate the likely induction period for tamoxifen.</p> <p>Results</p> <p>In total, 35 cases of PD were identified among the 15,419 breast cancer patients. No overall effect of tamoxifen on rate of PD was observed (HR = 1.3, 95% CI: 0.64-2.5), but a PD hazard ratio of 5.1 (95% CI: 1.0-25) was seen four to six years following initiation of tamoxifen treatment.</p> <p>Conclusions</p> <p>These results provide evidence that the neuro-protective properties of estrogen against PD occurrence may be disrupted by tamoxifen therapy. Tamoxifen treatments may be associated with an increased rate of PD; however these effects act after four years, are of limited duration, and the adverse effect is overwhelmed by the protection against breast recurrence conferred by tamoxifen therapy.</p

    “It’s all about asking from those who have walked the path”: Patient and stakeholder perspectives on how peers may shift substance use stigma in HIV care in South Africa

    Get PDF
    South Africa has the highest number of people with HIV (PWH) globally and a significant burden of co-occurring substance use disorder (SUD). Health care worker (HCW) stigma towards SUD is a key barrier to HIV care engagement among PWH with SUD. Support from peers—individuals with lived experience of SUD—may be a promising solution for addressing SUD stigma, while also improving engagement in HIV care. We evaluated the perceived acceptability of integrating a peer role into community-based HIV care teams as a strategy to address SUD stigma at multiple levels and improve patient engagement in HIV care. Patients and stakeholders (N = 40) were recruited from publicly-funded HIV and SUD organizations in Cape Town, South Africa. We conducted a quantitative assessment of stigma among stakeholders using an adapted Social Distance Scale (SDS) and patient perceptions of working with a peer, as well as semi-structured interviews focused on experiences of SUD stigma, acceptability of a peer model integrated into community-based HIV care, and potential peer roles. On the SDS, 75% of stakeholders had high stigma towards a patient with SUD, yet 90% had low stigma when in recovery for at least 2 years. All patients endorsed feeling comfortable talking to someone in recovery and wanting them on their HIV care team. Three main themes emerged from the qualitative data: (1) patient-reported experiences of enacted SUD and HIV stigmas were common and impacted HIV care engagement; (2) both patients and stakeholders considered a peer model highly acceptable for integration into HIV care to support engagement and address SUD stigma; and (3) patients and stakeholders identified both individual-level and systems-level roles for peers, how peers could work alongside other providers to improve patient care, and key characteristics that peers would need to be successful in these roles. Findings from this formative work point to the promise of a peer model for reducing SUD stigma among patients and HCWs within community-based HIV care teams in SA.https://doi.org/10.1186/s13722-022-00330-
