Evaluation of an Advocacy Programme for Mental Health Care Users in South Africa: A Mixed Methods Study.

This study evaluates the implementation of a national advocacy programme for mental health care users, conducted by the South African National Department of Health and the South African Federation for Mental Health. Semi-structured interviews were conducted with care users (n = 18), service providers (n = 9), support persons (n = 6), NGO directors (n = 4), and programme managers in the DoH (n = 4). Although informational benefits were highlighted from programme empowerment sessions, very few advocacy groups were subsequently established. Barriers to establishing and conducting advocacy groups included a lack of follow-up support, pervasive stigma from communities and health care workers, low self-confidence, and a lack of financial resources. Facilitators for establishment of groups included conducting empowerment sessions and identifying 'mental health champions' at clinics, improving mental health training for health workers, dispensing psychiatric medication to patients on the same day, providing funding for non-governmental organisations, conducting national awareness campaigns, and establishing holistic rehabilitation centres for care users.

Associations Between Patterns of Alcohol Use and Viral Load Suppression Amongst Women Living with HIV in South Africa.

This study aimed to identify alcohol use patterns associated with viral non-suppression among women living with HIV (WLWH) and the extent to which adherence mediated these relationships. Baseline data on covariates, alcohol consumption, ART adherence, and viral load were collected from 608 WLWH on ART living in the Western Cape, South Africa. We defined three consumption patterns: no/light drinking (drinking ≤ 1/week and ≤ 4 drinks/occasion), occasional heavy episodic drinking (HED) (drinking > 1 and ≤ 2/week and ≥ 5 drinks/occasion) and frequent HED (drinking ≥ 3 times/week and ≥ 5 drinks/occasion). In multivariable analyses, occasional HED (OR 3.07, 95% CI 1.78-5.30) and frequent HED (OR 7.11, 95% CI 4.24-11.92) were associated with suboptimal adherence. Frequent HED was associated with viral non-suppression (OR 2.08, 95% CI 1.30-3.28). Suboptimal adherence partially mediated the relationship between frequent HED and viral non-suppression. Findings suggest a direct relationship between frequency of HED and viral suppression. Given the mediating effects of adherence on this relationship, alcohol interventions should be tailored to frequency of HED while also addressing adherence.

Predictors of receiving a diagnosis, referral and treatment of depression in people on antiretroviral therapy in South African primary care: a secondary analysis of data from a randomised trial.

OBJECTIVE: To describe the receipt of a diagnosis, referral and treatment for depression in people receiving antiretroviral therapy (ART), with depressive symptoms and attending primary care clinics in South Africa, and investigate factors associated with receiving these components of care. METHODS: This is a secondary analysis of data from a randomised controlled trial of an intervention intended to improve detection and treatment of depression in primary care patients receiving ART. In this analysis, we combined cross-sectional and longitudinal data from the intervention and control arms. Using regression models and adjusting for intra-cluster correlation of outcomes, we investigated associations between socioeconomic characteristics, depressive symptoms, stress, disability and stigma, and receipt of a diagnosis, referral and treatment for depression. RESULTS: Of 2002 participants enrolled, 18% reported a previous diagnosis of depression by a healthcare worker and 10% reported having received counselling from a specialist mental health worker. Diagnosis, referral and counselling during the follow-up period were appropriately targeted, being independently more frequent in participants with higher enrolment scores for depressive symptoms, stress or disability. Participants with higher stigma scores at enrolment were independently less likely to receive counselling. Severe socio-economic deprivation was common but was not associated with treatment. CONCLUSION: While the receipt of a diagnosis, referral and treatment for depression were uncommon, they seemed to be appropriately targeted. Socio-economic deprivation was not associated with treatment.

OBJECTIF: Décrire la réception d'un diagnostic, de l'orientation et du traitement pour la dépression chez les personnes recevant un traitement antirétroviral (ART), présentant des symptômes dépressifs et fréquentant des cliniques de soins primaires en Afrique du Sud, et étudier les facteurs associés à la réception de ces éléments de soins. MÉTHODES: Il s'agit ici d'une analyse secondaire des données d'un essai contrôlé randomisé d'une intervention destinée à améliorer la détection et le traitement de la dépression chez les patients sous ART dans les soins primaires. Dans cette analyse, nous avons combiné les données transversales et longitudinales des bras d'intervention et témoin. En utilisant des modèles de régression et en ajustant la corrélation intra-grappes des résultats, nous avons étudié les associations entre les caractéristiques sociodémographiques, les symptômes dépressifs, le stress, l'invalidité et la stigmatisation, et la réception d'un diagnostic, d'une orientation et d'un traitement pour la dépression. RÉSULTATS: Sur 2.002 participants inscrits, 18% ont déclaré un diagnostic antérieur de dépression par un agent de santé et 10% ont déclaré avoir reçu des conseils d'un agent spécialisé pour la santé mentale. Le diagnostic, l'orientation et le conseil pendant la période de suivi ont été ciblés de manière appropriée, étant indépendamment plus fréquents chez les participants ayant des scores d'inscription plus élevés pour les symptômes dépressifs, le stress ou l'invalidité. Les participants ayant des scores de stigmatisation plus élevés à l'inscription étaient indépendamment moins susceptibles de recevoir des conseils. La privation socioéconomique sévère était courante mais n'était pas associée au traitement. CONCLUSION: Bien que la réception d'un diagnostic, l'orientation et le traitement de la dépression soient rares, ils semblaient bien ciblés. La privation socioéconomique n'était pas associée au traitement.

The influence of socioeconomic position on adjuvant treatment of stage III colon cancer: a systematic review and meta-analysis.

BACKGROUND: Patients with colon cancer (CC) with low socioeconomic position (SEP) have a worse survival than patients with high SEP. We investigated the association between different socioeconomic indicators and the steps in the treatment trajectory leading to initiation of adjuvant chemotherapy (ACT) for patients with stage III CC. MATERIALS AND METHODS: A systematic review and meta-analyses were conducted in accordance with the MOOSE checklist. MEDLINE and EMBASE were searched for eligible studies. Meta-analyses were performed on the separate socioeconomic indicators with the random-effects model. The heterogeneity across studies was assessed by the Q and the I 2 statistic. RESULTS: In total, 27 observational studies were included. SEP was measured by insurance, income, poverty, employment, education, or an index on an area or individual level. SEP, regardless of indicator, was negatively associated with the steps in the treatment trajectory leading to initiation of ACT among patients with resected stage III CC. The meta-analyses showed that patients with low SEP had a significantly lower odds of receiving ACT and increased odds of delayed treatment start, whereas SEP had no impact on the choice of therapy: combination or single-agent therapy. CONCLUSION: SEP was associated with less initiation of and higher risk for delayed initiation of ACT. Our findings suggest there is a social disparity in receipt of ACT in patients with stage III CC.

Impact of integrated district level mental health care on clinical and functioning outcomes of people with depression and alcohol use disorder in Nepal: a non-randomised controlled study.

BACKGROUND: Integration of mental health services into primary healthcare is proliferating in low-resource countries. We aimed to evaluate the impact of different compositions of primary care mental health services for depression and alcohol use disorder (AUD), when compared to usual primary care services. METHODS: We conducted a non-randomized controlled study in rural Nepal. We compared treatment outcomes among patients screening positive and receiving: (a) primary care mental health services without a psychological treatment component (TG); (b) the same services including a psychological treatment (TG + P); and (c) primary care treatment as usual (TAU). Primary outcomes included change in depression and AUD symptoms, as well as disability. Disability was measured using the 12-item WHO Disability Assessment Schedule. Symptom severity was assessed using the 9-item Patient Health Questionnaire for depression, the 10-item Alcohol Use Disorders Identification Test for AUD. We used negative binomial regression models for the analysis. RESULTS: For depression, when combining both treatment groups (TG, n = 77 and TG + P, n = 60) compared to TAU (n = 72), there were no significant improvements. When only comparing the psychological treatment group (TG + P) with TAU, there were significant improvements for symptoms and disability (aß = - 2.64; 95%CI - 4.55 to - 0.74, p = 0.007; aß = - 12.20; 95%CI - 19.79 to - 4.62; p = 0.002, respectively). For AUD, when combining both treatment groups (TG, n = 92 and TG + P, n = 80) compared to TAU (n = 57), there were significant improvements in AUD symptoms and disability (aß = - 15.13; 95%CI - 18.63 to - 11.63, p < 0.001; aß = - 9.26; 95%CI - 16.41 to - 2.12, p = 0.011; respectively). For AUD, there were no differences between TG and TG + P. Patients' perceptions of health workers' skills in common psychological factors were associated with improvement in depression patient outcomes (ß = - 0.36; 95%CI - 0.55 to - 0.18; p < 0.001) but not for AUD patients. CONCLUSION: Primary care mental health services for depression may only be effective when psychological treatments are included. Health workers' competencies as perceived by patients may be an important indicator for treatment effect. AUD treatment in primary care appears to be beneficial even without additional psychological services.

The effect of rate of torque development on motor unit recruitment and firing rates during isometric voluntary trapezoidal contractions.

It is common practice to examine motor unit (MU) activity according to mean firing rate (MFR) and action potential amplitude (MUAPAMP) vs. recruitment threshold (RT) relationships during isometric trapezoidal contractions. However, it is unknown whether the rate of torque development during the linearly increasing torque phase affects the activity of MUs during such contractions. Sixteen healthy males and females performed two isometric trapezoidal muscle actions at 40% of maximum voluntary contraction (MVC), one at a rate of torque development of 5% MVC/s (SLOW40) and one at 20% MVC/s (FAST40) during the linearly increasing torque phase. Surface electromyography (EMG) was recorded from the vastus lateralis (VL) via a 5-pin surface array sensor and decomposed into action potential trains of individual MUs, yielding MFRs and MUAPAMP which were regressed against RT separately for each contraction. Surface EMG amplitude recorded from leg extensors and flexors was used to quantify muscle activation and coactivation. MFR vs. RT relationship slopes were more negative (P = 0.003) for the SLOW40 (- 0.491 ± 0.101 pps/%MVC) than FAST40 (- 0.322 ± 0.109 pps/%MVC) and the slopes of the MUAPAMP vs. RT relationships (P = 0.022, SLOW40 = 0.0057 ± 0.0021 mV/%MVC, FAST40 = 0.0041 ± 0.0023 mV/%MVC) and muscle activation of the extensors (P < 0.001, SLOW40 = 36.3 ± 7.82%, FAST40 = 34.0 ± 6.26%) were greater for SLOW40 than FAST40. MU firing rates were lower and action potential amplitudes were larger in relation to recruitment thresholds for a contraction performed at a slower rate compared to a faster rate of isometric torque development. Differences in MU activity can exist as a function of rate of torque development during commonly performed isometric trapezoidal contractions.

Can mental health treatments help prevent or reduce intimate partner violence in low- and middle-income countries? A systematic review.

BACKGROUND: Epidemiological research suggests an interrelationship between mental health problems and the (re)occurrence of intimate partner violence (IPV). However, little is known about the impact of mental health treatments on IPV victimization or perpetration, especially in low- and middle-income countries (LMIC). METHODS: We conducted a systematic review to identify prospective, controlled studies of mental health treatments in LMIC. We defined 'mental health treatment' as an intervention for individuals experiencing mental ill health (including substance misuse) including a substantial psychosocial or pharmacological component. Studies had to measure a mental health and IPV outcome. We searched across multi-disciplinary databases using a structured search strategy. Screening of title/abstracts and full-text eligibility assessments were conducted by two researchers independently, data were extracted using a piloted spreadsheet, and a narrative synthesis was generated. RESULTS: We identified seven studies reported in 11 papers conducted in five middle-income countries. With the exception of blinding, studies overall showed acceptable levels of risk of bias. Four of the seven studies focused on dedicated mental health treatments in various populations, including: common mental disorders in earthquake survivors; depression in primary care; alcohol misuse in men; and alcohol misuse in female adult sex workers. The dedicated mental health treatments targeting depression or alcohol misuse consistently reduced levels of these outcomes. The two studies targeting depression also reduced short-term IPV, but no IPV benefits were identified in the two alcohol-focused studies. The other three studies evaluated integrated interventions, in which a focus on substance misuse was part of efforts to reduce HIV/AIDS and violence against particularly vulnerable women. In contrast to the dedicated mental health interventions, the integrated interventions did not consistently reduce mental ill health or alcohol misuse compared to control conditions. CONCLUSIONS: Too few studies have been conducted to judge whether mental health treatments may provide a beneficial strategy to prevent or reduce IPV in LMIC. Key future research questions include: whether promising initial evidence on the effects of depression interventions on reducing IPV hold more broadly, the required intensity of mental health components in integrated interventions, and the identification of mechanisms of IPV that are amenable to mental health intervention.

The incidence of bone marrow oedema at the sacroiliac joints in a non-rheumatological population - a retrospective cohort study.

BACKGROUND: The purpose of this study is to determine the incidence of bone marrow oedema (BME) at magnetic resonance imaging (MRI) of the sacroiliac joints (SIJ) in a non- rheumatological population, and to explore whether patient-reported outcome measures are suitable for predicting BME at the SIJ at referral. Furthermore, to investigate the final clinical diagnoses three months after initial SIJ MRI. METHODS: This study was a retrospective cohort study consisting of patients 18-45 years of age that were referred for a SIJ MRI between 1 July 2016 to 30 June 2017 at the Department of Radiology in Lillebaelt Hospital, Denmark. The SIJ MRI radiological reports were evaluated for signs of BME. Principal and secondary diagnoses according to the 10th version of International Classification of Diseases (ICD-10)-three months after the initial MRI-were identified in the electronic patient record system. For a subgroup of patients, patient- reported outcome measures, such as the 23-item Roland Morris Disability Questionnaire, quality of life and pain intensity in the back and leg were included from the local SpineData database. RESULTS: In total, 333 patients were included, and 187 (56.2%) of those patients received a final diagnosis within three months after the SIJ MRI. BME was detected in 63 (18.9%) patients; 17 (9.1%) patients had both BME at SIJ MRI and were diagnosed with spondyloarthritis (M45/M46). There was no statistically significant difference between patients with and without BME regarding demographics, quality of life, pain descriptions or function. CONCLUSIONS: The incidence of BME in the cohort correlates well to previous studies regarding the incidence of SIJ MRI changes in non-rheumatological populations in Denmark. Patient-reported outcome measures do not seem to contribute to identifying patients with early-phase BME in a non-rheumatological population.

Socio-economic variations in the mental health treatment gap for people with anxiety, mood, and substance use disorders: results from the WHO World Mental Health (WMH) surveys.

BACKGROUND: The treatment gap between the number of people with mental disorders and the number treated represents a major public health challenge. We examine this gap by socio-economic status (SES; indicated by family income and respondent education) and service sector in a cross-national analysis of community epidemiological survey data. METHODS: Data come from 16 753 respondents with 12-month DSM-IV disorders from community surveys in 25 countries in the WHO World Mental Health Survey Initiative. DSM-IV anxiety, mood, or substance disorders and treatment of these disorders were assessed with the WHO Composite International Diagnostic Interview (CIDI). RESULTS: Only 13.7% of 12-month DSM-IV/CIDI cases in lower-middle-income countries, 22.0% in upper-middle-income countries, and 36.8% in high-income countries received treatment. Highest-SES respondents were somewhat more likely to receive treatment, but this was true mostly for specialty mental health treatment, where the association was positive with education (highest treatment among respondents with the highest education and a weak association of education with treatment among other respondents) but non-monotonic with income (somewhat lower treatment rates among middle-income respondents and equivalent among those with high and low incomes). CONCLUSIONS: The modest, but nonetheless stronger, an association of education than income with treatment raises questions about a financial barriers interpretation of the inverse association of SES with treatment, although future within-country analyses that consider contextual factors might document other important specifications. While beyond the scope of this report, such an expanded analysis could have important implications for designing interventions aimed at increasing mental disorder treatment among socio-economically disadvantaged people.

The effect of geriatric intervention in frail elderly patients receiving chemotherapy for colorectal cancer: a randomized trial (GERICO).

BACKGROUND: Better surgical techniques, chemotherapy and biological therapy have improved survival in patients with colorectal cancer (CRC), most markedly in younger patients. About half of patients over 70 years receive dose reductions or early treatment discontinuation of the planned adjuvant or first-line treatment due to side effects. The Comprehensive Geriatric Assessment (CGA) is a multidisciplinary evaluation of an elderly individual's health status. This assessment in older patients with cancer can predict survival, chemotherapy toxicity and morbidity. METHODS: This randomized phase II trial (GERICO) is designed to investigate whether comprehensive geriatric assessment and intervention before and during treatment with chemotherapy in frail elderly patients with stages II-IV CRC will increase the number of patients completing chemotherapy. All patients ≥70 years in whom chemotherapy for CRC is planned to start at Herlev and Gentofte Hospital are screened for frailty using the G8 questionnaire at the first visit to the outpatient clinic. The G8 questionnaire is a multi-domain screening tool to identify frail or vulnerable patients at risk of increased toxicity and morbidity. Frail patients are offered inclusion and are then randomized to two groups (the intervention group and the control group). Patients in the intervention group receive a full geriatric assessment of comorbidity, medication, psycho-cognitive function, physical, functional and nutrition status, and interventions are undertaken on identified health issues. Simultaneously, they are treated for their cancer according to international guidelines. Patients in the control group receive the same chemotherapy regimens and standard of care. Primary outcome is number of patients completing scheduled chemotherapy at starting dose. Secondary outcomes are dose reductions, treatment delays, toxicity, time to recurrence, survival, cancer-related mortality and quality of life. DISCUSSION: This ongoing trial is one of the first to evaluate the effect of geriatric intervention in frail elderly patients with CRC. The trial will provide new and valuable knowledge about whether it is beneficial for the elderly patient undergoing chemotherapy to be treated simultaneously by a geriatrician. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT02748811 . The trial was registered retrospectively; registration date 04/28/2016.

Minocycline added to subcutaneous interferon ß-1a in multiple sclerosis: randomized RECYCLINE study.

BACKGROUND AND PURPOSE: Combining different therapies may improve disease control in patients with relapsing-remitting multiple sclerosis (RRMS). This study assessed the efficacy and safety of minocycline added to subcutaneous (sc) interferon (IFN) ß-1a therapy. METHODS: This was a double-blind, randomized, placebo-controlled multicentre study. Within 3 months (±1 month) of starting sc IFN ß-1a 44 µg three times weekly, patients with RRMS were randomized to minocycline 100 mg twice daily or placebo, added to sc IFN ß-1a, for 96 weeks. The primary efficacy endpoint was the time to first qualifying relapse. Secondary efficacy endpoints were the annualized relapse rate for qualifying relapses, the number of new/enlarging T2-weighted lesions and change in brain volume [magnetic resonance imaging (MRI) was performed only in a few selected centres]. In addition, a number of tertiary efficacy endpoints were assessed. RESULTS: One hundred and forty-nine patients received minocycline and 155 received placebo; MRI data were available for 23 and 27 patients, respectively. The time to first qualifying relapse did not differ significantly for minocycline versus placebo (hazard ratio 0.85; 95% confidence interval 0.53, 1.35; log-rank = 0.50; P = 0.48). There were no statistically significant differences between the two groups on other efficacy endpoints, although some numerical trends in favour of minocycline were observed. No unexpected adverse events were reported, but more patients discontinued because of adverse events with minocycline versus placebo. CONCLUSION: Minocycline showed no statistically significant beneficial effect when added to sc IFN ß-1a therapy.

Cost-effectiveness of the Mental Health and Development model for schizophrenia-spectrum and bipolar disorders in rural Kenya.

BACKGROUND: The treatment gap for serious mental disorders across low-income countries is estimated to be 89%. The model for Mental Health and Development (MHD) offers community-based care for people with mental disorders in 11 low- and middle-income countries. METHOD: In Kenya, using a pre-post design, 117 consecutively enrolled participants with schizophrenia-spectrum and bipolar disorders were followed-up at 10 and 20 months. Comparison outcomes were drawn from the literature. Costs were analysed from societal and health system perspectives. RESULTS: From the societal perspective, MHD cost Int$ 594 per person in the first year and Int$ 876 over 2 years. The cost per healthy day gained was Int$ 7.96 in the first year and Int$ 1.03 over 2 years - less than the agricultural minimum wage. The cost per disability-adjusted life year averted over 2 years was Int$ 13.1 and Int$ 727 from the societal and health system perspectives, respectively, on par with antiretrovirals for HIV. CONCLUSIONS: MHD achieved increasing returns over time. The model appears cost-effective and equitable, especially over 2 years. Its affordability relies on multi-sectoral participation nationally and internationally.

Assessment of acute stroke cerebral CT examinations by anaesthesiologists.

BACKGROUND AND PURPOSE: It is essential to diagnose ischaemic stroke as soon as possible after symptom onset, so that thrombolytic treatment can be initiated as quickly as possible. This might be greatly facilitated if cerebral CT could be carried out in a pre-hospital setting. The aim of this study was to evaluate if anaesthesiologists, who in Norway provide pre-hospital medical care, could be trained to assess cerebral CT scans to exclude radiological contraindications for thrombolytic stroke treatment. METHODS: Thirteen anaesthesiologists attended an 8-h course in acute stroke assessment, including a 2-h introduction to the neuroradiology of acute stroke. Each participant then assessed 12 non-contrast cerebral CT examinations of acute stroke patients with specific regard to radiological contraindications for thrombolytic therapy. Test results were compared with those of three experienced neuroradiologists. Inter-rater agreement between anaesthesiologists and neuroradiologists was calculated using Cohen's Kappa statistics. Robustness of the results was assessed using the non-parametric bootstrap. RESULTS: Among the neuroradiologists, Kappa was 1 for detecting radiological contraindications for thrombolytic therapy. Twelve of the 13 anaesthesiologists showed good or excellent agreement (Kappa > 0.60) with the neuroradiologists. The anaesthesiologists spent a median time of 2 min and 18 s on each CT scan. CONCLUSIONS: This study suggests that anaesthesiologists who are experienced in pre-hospital care may be quickly trained to assess cerebral CT examinations in acute stroke patients with regard to radiological contraindications for thrombolytic therapy.

Consensus statement: the 16th Annual Western Canadian Gastrointestinal Cancer Consensus Conference; Saskatoon, Saskatchewan; September 5-6, 2014.

The 16th annual Western Canadian Gastrointestinal Cancer Consensus Conference was held in Saskatoon, Saskatchewan, September 4-5, 2014. The Consensus Conference is an interactive, multidisciplinary event attended by health care professionals from across western Canada (British Columbia, Alberta, Saskatchewan, and Manitoba) involved in the care of gastrointestinal cancer. Surgical, medical, and radiation oncologists; pathologists; radiologists; and allied health care professionals participated in presentation and discussion sessions for the purposes of developing the recommendations presented here. This consensus statement addresses current issues in the management of colorectal cancer.

Multiple sclerosis and seizures: incidence and prevalence over 40 years.

OBJECTIVES: The prevalence of multiple sclerosis (MS) is increasing worldwide. Epileptic seizures are more common in MS patients than in the general population. The aim of this study was to investigate changes in the prevalence and incidence of MS in a well-defined population over several decades and estimate the occurrence of epilepsy in the same cohort. MATERIALS AND METHODS: Patients diagnosed with MS in the County of Vestfold, Norway in the period of 1983-2003 were identified. Point prevalence for MS and epilepsy was calculated for January 1, 2003. The average annual incidence rates were calculated in five-year periods from 1983 to 2002. These numbers were compared to previously published figures of prevalence from 1963 and incidence from 1953. RESULTS: On prevalence day, we identified 364 patients diagnosed with MS living in Vestfold. Thus, the prevalence increased from 61.6/100,000 in 1963 to 166.8/100,000 in 2003. In the period 1983-2002, the annual incidence fluctuated between 4.2 and 7.3/100,000/year (mean 4.5, 95% CI 3.6 - 5.5). In 2003, the portion of MS patients with epileptic seizures was 7.4%, compared to 2.9% in 1963. CONCLUSIONS: During the 40 years follow-up of this population, the incidence of MS was stable, while the prevalence of MS and the share of MS patients with epileptic seizures increased. Compared to the general population, the risk of having active epilepsy was increased fourfold. We assume that this is a consequence of an increased survival in MS patients.

Prospective Longitudinal Assessment of Quality of Life After Stereotactic Ablative Radiotherapy for Oligometastases: Analysis of the Population-based SABR-5 Phase II Trial.

AIMS: To evaluate longitudinal patient-reported quality of life (QoL) in patients treated with stereotactic ablative radiotherapy (SABR) for oligometastases. MATERIALS AND METHODS: The SABR-5 trial was a population-based single-arm phase II study of SABR to up to five sites of oligometastases, conducted in six regional cancer centres in British Columbia, Canada from 2016 to 2020. Prospective QoL was measured using treatment site-specific QoL questionnaires at pre-treatment baseline and at 3, 6, 9, 12, 15, 18, 21, 24, 30 and 36 months after treatment. Patients with bone metastases were assessed with the Brief Pain Inventory (BPI). Patients with liver, adrenal and abdominopelvic lymph node metastases were assessed with the Functional Assessment of Chronic Illness Therapy-Abdominal Discomfort (FACIT-AD). Patients with lung and intrathoracic lymph node metastases were assessed with the Prospective Outcomes and Support Initiative (POSI) lung questionnaire. The two one-sided test procedure was used to assess equivalence between the worst QoL score and the baseline score of individual patients. The mean QoL at all time points was used to determine the trajectory of QoL response after SABR. The proportion of patients with 'stable', 'improved' or 'worsened' QoL was determined for all time points based on standard minimal clinically important differences (MCID; BPI worst pain = 2, BPI functional interference score [FIS] = 0.5, FACIT-AD Trial Outcome Index [TOI] = 8, POSI = 3). RESULTS: All enrolled patients with baseline QoL assessment and at least one follow-up assessment were analysed (n = 133). On equivalence testing, the patients' worst QoL scores were clinically different from baseline scores and met MCID (BPI worst pain mean difference: 1.8, 90% confidence interval 1.19 to 2.42]; BPI FIS mean difference: 1.68, 90% confidence interval 1.15 to 2.21; FACIT-AD TOI mean difference: -8.76, 90% confidence interval -11.29 to -6.24; POSI mean difference: -4.61, 90% confidence interval -6.09 to -3.14). However, the mean FIS transiently worsened at 9, 18 and 21 months but eventually returned to stable levels. The mean FACIT and POSI scores also worsened at 36 months, albeit with a limited number of responses (n = 4 and 8, respectively). Most patients reported stable QoL at all time points (range: BPI worst pain 71-82%, BPI FIS 45-78%, FACIT-AD TOI 50-100%, POSI 25-73%). Clinically significant stability, worsening and improvement were seen in 70%/13%/18% of patients at 3 months, 53%/28%/19% at 18 months and 63%/25%/13% at 36 months. CONCLUSIONS: Transient decreases in QoL that met MCID were seen between patients' worst QoL scores and baseline scores. However, most patients experienced stable QoL relative to pre-treatment levels on long-term follow-up. Further studies are needed to characterise patients at greatest risk for decreased QoL.

Predictors of Quality of Life Decline in Patients with Oligometastases treated with Stereotactic Ablative Radiotherapy: Analysis of the Population-Based SABR-5 Phase II Trial.

AIMS: Most patients experience stable quality of life (QoL) after stereotactic ablative radiotherapy (SABR) treatment for oligometastases. However, a subset of patients experience clinically relevant declines in QoL on post-treatment follow-up. This study aimed to identify risk factors for QoL decline. MATERIALS AND METHODS: The SABR-5 trial was a population-based single-arm phase II study of SABR to up to five sites of oligometastases. Prospective QoL was measured using treatment site-specific tools at pre-treatment baseline and 3, 6, 9, 12, 15, 18, 21, 24, 30 and 36 months after treatment. The time to persistent QoL decline was calculated as the time from SABR to the first decline in QoL score meeting minimum clinically important difference with no improvement to baseline score on subsequent assessments. Univariable and multivariable logistic regression analyses were carried out to determine factors associated with QoL decline. RESULTS: One hundred and thirty-three patients were included with a median follow-up of 32 months (interquartile range 25-43). Thirty-five patients (26%) experienced a persistent decline in QoL. The median time until persistent QoL decline was not reached. The cumulative incidence of QoL decline at 2 and 3 years were 22% (95% confidence interval 14.0-29.6) and 40% (95% confidence interval 28.0-51.2), respectively. In multivariable analysis, disease progression (odds ratio 5.23, 95% confidence interval 1.59-17.47, P = 0.007) and adrenal metastases (odds ratio 9.70, 95% confidence interval 1.41-66.93, P = 0.021) were associated with a higher risk of QoL decline. Grade 3 or higher (odds ratio 3.88, 95% confidence interval 0.92-16.31, P = 0.064) and grade 2 or higher SABR-associated toxicity (odds ratio 2.24, 95% confidence interval 0.85-5.91, P = 0.10) were associated with an increased risk of QoL decline but did not reach statistical significance. CONCLUSIONS: Disease progression and adrenal lesion site were associated with persistent QoL decline following SABR. The development of grade 3 or higher toxicities was also associated with an increased risk, albeit not statistically significant. Further studies are needed, focusing on the QoL impact of metastasis-directed therapies.

Stoppers and non-starters of disease-modifying treatment in multiple sclerosis.

OBJECTIVES: To explore the frequency of non-starters and stoppers of disease-modifying therapy (DMT) in a cohort of people recently diagnosed with multiple sclerosis (MS) and to identify reasons for non-starting or stopping DMT measured by demographic variables, social support [The Interpersonal Support Evaluation List (ISEL)] and disease-related stress [The Impact of Event Scale (IES)]. MATERIALS AND METHODS: A multicentre retrospective cohort study using postal surveys completed by people with MS was performed, comprising all patients diagnosed with MS during 2000-2007 at four university clinics in Norway. RESULTS: Of the 424 respondents, 180 (42%) were still using the first prescribed DMT, 83 (20%) were using DMT after switching DMT at least once, 53 (12.5%) had ended DMT, and 108 (25.5%) had never started DMT. The risk of non-starting DMT was associated with increasing age at diagnosis, the region, disease-related stress and avoidant trauma coping. The risk factors for stopping therapy after the first prescribed DMT were adverse events and high education. CONCLUSIONS: Disease-related stress, avoidant trauma coping, age at diagnosis and education should be considered when motivating people with MS to use DMT. Hence, the challenges to starting and continuing treatment will probably also remain a problem with orally administered DMT.

Test-retest reliability of the Xhosa version of the Diagnostic Interview Schedule for Children.

BACKGROUND: The Diagnostic Interview Schedule for Children (DISC-IV) is a widely used structured psychiatric diagnostic instrument for children that is designed to be administered by non-clinicians. Although reliability data on several versions of the DISC are available, none have assessed the Xhosa version for use in the South African context. The objective of this study was to examine the test-retest reliability of the Xhosa version of the DISC-IV. METHODS: Test-retest reliabilities were documented for a sample of 105 parent/care giver and youth pairs. The research assistants worked in pairs, one interviewed the parent and the other interviewed the youth. The same researchers returned after approximately 2 weeks to conduct the second interviews. RESULTS: The DISC-IV was reliable across informants for many psychiatric disorders. Kappa coefficients ranged from 0.448 (any anxiety disorder) to 0.662 (major depressive disorder) for parent reports and from 0.145 (anxiety) to 0.661 (major depressive disorder) for child reports. CONCLUSION: The results of this study suggest that the test-retest reliability of the Xhosa version of the DISC-IV is similar to the reliability reported in other translated versions of the instrument. The satisfactory reliability and straightforward application make this instrument suitable for use in South Africa.

Exploring effort-reward imbalance and professional quality of life among health workers in Cape Town, South Africa: a mixed-methods study.

BACKGROUND: In the context of a growing appreciation for the wellbeing of the health workforce as the foundation of high-quality, sustainable health systems, this paper presents findings from two complementary studies to explore occupational stress and professional quality of life among health workers that were conducted in preparation for a task-shifting intervention to improve antenatal mental health services in Cape Town. METHODS: This mixed-methods, cross-sectional study was conducted in public sector Midwife Obstetric Units and associated Non-Profit Organisations in Cape Town. Semi-structured interviews and a quantitative survey were conducted among facility-and community-based professional and lay health workers. The survey included demographic as well as effort-reward imbalance (ERI) and professional quality of life (PROQOL) questionnaires to examine overall levels of work-related psychosocial stress and professional quality of life, as well as differences between lay and professional health workers. Qualitative data was analysed using a thematic content analysis approach. Quantitative data was analysed using STATA 12. RESULTS: Findings from 37 qualitative interviews highlighted the difficult working conditions and often limited reward and support structures experienced by health workers. Corroborating these findings, our quantitative survey of 165 professional and lay health workers revealed that most health workers experienced a mismatch between efforts spent and rewards gained at work (61.1% of professional and 70.2% of lay health workers; p = 0.302). There were few statistically significant differences in ERI and PROQOL scores between professional and lay health workers. Although Compassion Satisfaction was high for all health worker groups, lay health workers also showed elevated levels of burnout and compassion fatigue, with community-based health workers particularly affected. CONCLUSIONS: Findings of this study add to the existing evidence base on adverse working conditions faced by South African public-sector health workers that should be taken into consideration as national and local governments seek to 're-engineer' South Africa's Primary Health Care system. Furthermore, they also highlight the importance of taking into consideration the wellbeing of health workers themselves to develop interventions that can sustainably foster resilient and high-quality health systems.
