Cost-Utility of Attachment-Based Compassion Therapy (ABCT) and Mindfulness-Based Stress Reduction (MBSR) in the Management of Depressive, Anxious, and Adjustment Disorders in Mental Health Settings: Economic Evaluation Alongside a Randomized Controlled Trial

ObjectivesThe main objective of this paper was to examine the cost-utility of attachment-based compassion therapy (ABCT) compared to Mindfulness-Based Stress Reduction (MBSR) and treatment-as-usual (TAU) on patients with depressive and/or anxious disorder, or adjustment disorder with depressive and/or anxious symptomatology in terms of effects on quality-adjusted life years (QALYs) as well as healthcare costs from a public healthcare system perspective.MethodA 6-month randomized controlled trial was conducted. Ninety Spanish patients with mental disorders (depressive, anxious, or adjustment disorders) received 8 weekly group sessions of TAU + ABCT, TAU + MBSR, or TAU alone. Data collection took place at pre- and 6-month follow-up. Cost-utility of the two treatment groups (ABCT vs MBSR vs TAU) was compared by examining treatment outcomes in terms of QALYs (obtained with the EQ-5D-3L) and healthcare costs (data about service use obtained with the Client Service Receipt Inventory).ResultsBoth MBSR and ABCT were more efficient than TAU alone, although the results did not reach statistical significance. Compared to ABCT, MBSR produced an increase both in terms of costs (euro53.69, 95% CI [- 571.27 to 513.14]) and effects (0.004 QALYs, 95% CI [- 0.031 to 0.049]); ICUR = euro13,422.50/QALY). Both interventions significantly reduced the number of visits to general practice compared to TAU.ConclusionsThis study has contributed to the evidence base of mindfulness- and compassion-based programs and provided promising information about the cost-utility of MBSR for patients with emotional disorders. However, the small sample size and short follow-up period limit the generalizability of the findings.PreregistrationClinicaltrials.gov; NCT03425487

Myliobatis freminvillii, bullnose eagle ray

The Bullnose Eagle Ray (Myliobatis freminvillii) is a medium-sized (to 106 cm disc width) demersal coastal eagle ray that occurs in the Northwest, Western Central, and Southwest Atlantic Oceans from Massachussetts, USA to the Texas coast of the Gulf of Mexico and from Venezuela to Buenos Aires, Argentina and inhabits continental shelves from the surface to a depth of 122 m. Its is captured by artisanal longlines, gillnets, beach seines and also in industrial shrimp trawls. In the Northwest Atlantic, population trend data are available from a deep-water trawl survey in the northern Gulf of Mexico that reveal steep increases in abundance over 2002-2013. There are no known threats in the Northwest and Western Central Atlantic, but in the Southwest Atlantic artisanal fisheries are intense. Further, there are largely unmanaged commercial trawl and longline fisheries in this area. This inshore eagle ray is exposed to intense and often unmanaged fishing pressure throughout the Southwest Atlantic portion of its range, and it has no refuge at depth. Due to the level of exploitation by widespread artisanal fisheries which lack adequate management, it is suspected that this species has undergone a population reduction of >80% over the past three generation lengths (44 years) in the Atlantic South American part of its range, but is stable in the Northwest and Western Central Atlantic. Overall, based on its range, with almost all threats found in the Southwest Atlantic, and the suspected low productivity of the species, the Bullnose Eagle Ray is suspected to have undergone a population reduction of 30-49% in the past three generation lengths (44 years) due to levels of exploitation, and it is assessed as Vulnerable A2bd.Fil: Carlson, J..

Fuzzy min-max neural networks for categorical data: application to missing data imputation

The fuzzy min–max neural network classifier is a supervised learning method. This classifier takes the hybrid neural networks and fuzzy systems approach. All input variables in the network are required to correspond to continuously valued variables, and this can be a significant constraint in many real-world situations where there are not only quantitative but also categorical data. The usual way of dealing with this type of variables is to replace the categorical by numerical values and treat them as if they were continuously valued. But this method, implicitly defines a possibly unsuitable metric for the categories. A number of different procedures have been proposed to tackle the problem. In this article, we present a new method. The procedure extends the fuzzy min–max neural network input to categorical variables by introducing new fuzzy sets, a new operation, and a new architecture. This provides for greater flexibility and wider application. The proposed method is then applied to missing data imputation in voting intention polls. The micro data—the set of the respondents’ individual answers to the questions—of this type of poll are especially suited for evaluating the method since they include a large number of numerical and categorical attributes

Myliobatis goodei, southern eagle ray

The Southern Eagle Ray (Myliobatis goodei) is a medium-sized (to at least 115 cm DW) coastal eagle ray that occurs in the Western Central and Southwest Atlantic Oceans from South Carolina and Florida, USA and Quintana Roo, Mexico to San Jorge Gulf, Santa Cruz, Argentina. It inhabits continental shelves from inshore to depths of 181 m. It is captured using artisanal longlines, gillnets, beach seines, and in industrial shrimp trawls. This species is inferred to be stable or increasing in the Western Central Atlantic, based on its similarity to the Bullnose Eagle Ray (Myliobatis freminvillei). In the Southwest Atlantic artisanal fisheries are intense, further there are largely unmanaged commercial trawl and longline fisheries in many areas. In Brazil, landings of eagle rays have been reduced by 60% over 2000?2012 in Santa Catarina State, and a reduction of 91% in Rio Grande do Sul since the 1980s. This inshore eagle ray has no refuge at depth and is exposed to intense and often unmanaged fishing pressure throughout the Atlantic South American portion of its range and there it is suspected that this species has undergone a population reduction of >80% over the past three generation lengths (44 years), but is stable in the Western Central Atlantic. Overall, based its range with the almost all threats found in the Southwest Atlantic, the suspected low productivity of the species, this species is suspected to have undergone a population reduction of 30 49% in three generation lengths (44 years) due to levels of exploitation, and it is assessed as Vulnerable A2d.Fil: Carlson, J..

Economic evaluation of videoconference group acceptance and commitment therapy and behavioral activation therapy for depression versus usual care among adults with chronic low back pain plus comorbid depressive symptoms

Altres ajuts: The authors are grateful to the CIBER of Epidemiology and Public Health (CIBERESP; CB06/02/0046 & CB22/02/00052)Chronic pain and depression are frequently comorbid conditions associated with significant healthcare and social costs.This study examined the cost-utility and cost-effectiveness of videoconference-based group forms of Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD), as a complement to treatment-as-usual (TAU), for patients with chronic low back pain (CLBP) plus depressive symptoms, compared to TAU alone. A trial-based economic evaluation (n = 234) was conducted from a governmental and healthcare perspective with a time horizon of 12 months. Primary outcomes were the Brief Pain Inventory-Interference Scale (BPI-IS) and Quality Adjusted Life Year (QALY). Compared to TAU, ACT achieved a significant reduction in total costs (d = 0.47), and BATD achieved significant reductions in indirect (d = 0.61) and total costs (d = 0.63). Significant improvements in BPI-IS (d = 0.73 and d = 0.66, respectively) and QALY scores (d = 0.46 and d = 0.28, respectively) were found in ACT and BATD compared to TAU. No significant differences in costs and outcomes were found between ACT and BATD. In the intention-to-treat analyses, from the governmental and healthcare perspective, no significant differences in cost reduction and incremental effects were identified in the comparison between ACT, BATD, and TAU. However, in the complete case analysis, significant incremental effects of ACT (∆BPI-IS = -1.57 and -1.39, respectively) and BATD (∆BPI-IS = -1.08 and -1.04, respectively) compared with TAU were observed. In the per-protocol analysis, only the significant incremental effects of ACT (∆BPI-IS = -1.68 and -1.43, respectively) compared to TAU were detected. In conclusion, ACT and BATD might be efficient options in the management of CLBP plus comorbid depression symptoms as compared to usual care. However, no clear difference was found in the comparison between the two active therapies regarding cost-effectiveness or cost-utility. PERSPECTIVE: The economic evaluation of psychological therapies for the management of complex conditions is crucial as can be used in decision-making and resource allocation. This study provides evidence that videoconference group-based forms of ACT and BATD are more effective and involve a greater reduction in costs than usual care in the management of CLBP plus comorbid depressive symptoms. Both psychological therapies seem to offer good value for money to the Spanish national health service and the government

Cost-utility of a psychoeducational intervention in fibromyalgia patients compared with usual care: an economic evaluation alongside a 12-month randomized controlled trial

Objective: To determine the effectiveness of adding psychoeducational treatment implemented in general practice to usual care for patients with fibromyalgia (FM), and to analyze the cost-utility of the intervention from health care and societal perspectives. Methods: Twelve-month randomized controlled trial. A total of 216 primary care patients meeting the American College of Rheumatology criteria for FM participated in the study. The intervention included 9, 2-hour sessions of psychoeducation (5 sessions of education about the illness + 4 sessions of autogenic relaxation) added to usual care provided by a multidisciplinary group in general practice was compared to usual care in the public health system. Results: At 12-month follow-up, patients who received psychoeducation showed greater improvement in global functional status (Cohen d = 0.36; -2.49 to 3.81), physical functioning (Cohen d = 0.56; 0.08 to 1.00), days feeling well (Cohen d = 0.40; -0.16 to 1.02), pain (Cohen d = 0.35; -0.04 to 0.80), morning fatigue (Cohen d = 0.24; -0.20 to 0.76), stiffness (Cohen d = 0.34; -0.10 to 0.87), and depression (Cohen d = 0.30; -0.26 to 0.93). Mean incremental cost per person receiving the intervention was €-215.49 (-615.13 to 287.81) from the health care perspective, and €-197.32 (-785.12 to 395.74) from the societal perspective. The incremental gain in quality-adjusted life-years per person was 0.12 (0.06 to 0.19), yielding a "dominant" intervention from both perspectives. The sensitivity analysis suggested that the intervention was cost-effective even imputing all missing data. Discussion: Our findings demonstrate the long-term clinical effectiveness of a psychoeducational treatment program for FM implemented at primary care level and the cost-utility from a health care and societal perspective
