To estimate the cost-effectiveness of olaparib after being funded by the Spanish National Health Service (SNHS) as first-line monotherapy maintenance treatment in patients with advanced high-grade serous ovarian carcinoma (HGSOC) and BRCA mutations in Spain. A semi-Markov model with one-month cycles was adapted to the Spanish healthcare setting, using the perspective of the SNHS, and a time horizon of 50 years. Two scenarios were compared: receiving olaparib vs. no maintenance treatment. The model comprised four health states and included the clinical results of the SOLO1 study, along with the direct healthcare costs associated with the use of first-line and subsequent treatment resources (2020 €). A discount rate of 3% was applied for future cost and quality-of-life outcomes. A probabilistic sensitivity analysis (PSA) was also carried out and a cost-effectiveness threshold of €25,000 per quality adjusted life year (QALY) was considered. The introduction of olaparib as a first-line maintenance treatment for advanced HGSOC patients with BRCA mutations implied a cost of €131,614.98 compared to €102,369.54 without olaparib (difference: €29,245.44), with an improvement of 2.00 QALYs (5.56 and 3.57, respectively). Therefore, olaparib is cost-effective for advanced HGSOC patients with BRCA mutations, with an incremental cost-effectiveness ratio of €14,653.2/QALY. The results from the PSA showed that 92.1% of the simulations fell below the €25,000/QALY threshold. The model showed that olaparib could improve the overall survival by 2 years, vs. no maintenance treatment. Olaparib as first-line maintenance treatment is cost-effective in advanced HGSOC patients with BRCA mutations in Spain. • Our results suggest that olaparib could delay disease progression and improve OS by 2 years vs. no maintenance treatment. • Treatment with olaparib resulted in a gain of 2.00 QALYs vs. no maintenance treatment, at an ICER of €14,653,2/QALY. • First-line maintenance with olaparib is cost-effective in advanced HGSOC patients with BRCA mutations in Spain.

Invasive meningococcal disease (IMD) is a severe infectious disease, mainly affecting children under 5 years, associated with long-term physical, neurological and psychological sequelae. In Spain, most IMD cases are caused by meningococcal serogroup B (MenB). This study estimates its economic burden from a societal perspective in Spain. A previously published bottom-up, model-based incidence costing approach by Scholz et al. (2019) to estimate the economic burden of MenB in Germany was adapted to the Spanish setting. Diagnosis and age-related costs for a hypothetical Spanish cohort were calculated over a lifetime horizon. Official Spanish databases, literature and expert opinion were used as data sources. The costs were updated to 2019 prices, and a 3% discount rate was applied. Direct costs related to the acute IMD phase, long-term sequelae, rehabilitation and public health response were considered. Indirect costs included productivity losses and premature mortality and were calculated using the human-capital approach (HCA) and friction-cost approach (FCA). Deterministic and probabilistic sensitivity analyses were also performed. At base-case, the total cost for a cohort of 142 patients (2017–2018 period) was €4.74 million (€33,484/case) using the FCA and €13.14 million (€92,768/case) using the HCA. Direct costs amounted to €4.65 million (€32,765/case). Sequelae costs represented 62.46% of the total cost using the FCA and 77.63% using the HCA. Deterministic sensitivity analysis showed that variation of ± 20% in the input parameter values (population, epidemiology, productivity, costs) had the greatest influence on the base-case results, and the probabilistic sensitivity analysis showed the probability of fitting base-case estimates was > 99%, both for FCA and HCA. MenB IMD is an uncommon but severe disease, with a high economic burden for Spanish society. The elevated costs per IMD case reflect its severity in each patient suffering this disease, especially due to the development of sequelae. [ABSTRACT FROM AUTHOR]

Upper gastrointestinal bleeding is defined as bleeding originating in the upper digestive tract proximal to the Treitz angle and is the most important gastroenterological emergency. Its incidence varies, depending on the area studied, between 48 and 160 cases per 100,000 inhabitants per year. Although it can be caused by numerous etiologies, we must not forget the less common ones such as a ruptured hepatic artery aneurysm since they can condition high mortality. We present a representative case. [ABSTRACT FROM AUTHOR]

Eutrophication is a main threat to continental aquatic ecosystems. Prevention and amelioration actions have been taken under the assumption of a stable climate, which needs reconsideration. Here, we show that reduced precipitation can bring a lake ecosystem to a more productive regime even with a decline in nutrient external load. By analyzing time series of several decades in the largest lake of the Iberian Peninsula, we found autocorrelated changes in the variance of state variables (i.e., chlorophyll and oxygen) indicative of a transient situation towards a new ecosystem regime. Indeed, exceptional planktonic diatom blooms have occurred during the last few years, and the sediment record shows a shift in phytoplankton composition and an increase in nutrient retention. Reduced precipitation almost doubled the water residence time in the lake, enhancing the relevance of internal processes. This study demonstrates that ecological quality targets for aquatic ecosystems must be tailored to the changing climatic conditions for appropriate stewardship. [ABSTRACT FROM AUTHOR]

Purpose: To determine the impact of non-cardiovascular comorbidities on the health-related quality of life (HRQoL) of patients with chronic heart failure (CHF).Methods: A scoping review of the scientific literature published between 2009 and 2019 was carried out. Observational studies which assessed the HRQoL of patients with CHF using validated questionnaires and its association with non-cardiovascular comorbidities were included.Results: The search identified 1904 studies, of which 21 fulfilled the inclusion criteria to be included for analysis. HRQoL was measured through specific, generic, or both types of questionnaires in 72.2%, 16.7%, and 11.1% of the studies, respectively. The most common comorbidities studied were diabetes mellitus (12 studies), mental and behavioral disorders (8 studies), anemia and/or iron deficiency (7 studies), and respiratory diseases (6 studies). Across studies, 93 possible associations between non-cardiovascular comorbidities and HRQoL were tested, of which 21.5% regarded anemia or iron deficiency, 20.4% mental and behavioral disorders, 20.4% diabetes mellitus, and 14.0% respiratory diseases. Despite the large heterogeneity across studies, all 21 showed that the presence of a non-cardiovascular comorbidity had a negative impact on the HRQoL of patients with CHF. A statistically significant impact on worse HRQoL was found in 84.2% of associations between mental and behavioral disorders and HRQoL (patients with depression had up to 200% worse HRQoL than patients without depression); 73.7% of associations between diabetes mellitus and HRQoL (patients with diabetes mellitus had up to 21.8% worse HRQoL than patients without diabetes mellitus); 75% of associations between anemia and/or iron deficiency and HRQoL (patients with anemia and/or iron deficiency had up to 25.6% worse HRQoL than between patients without anemia and/or iron deficiency); and 61.5% of associations between respiratory diseases and HRQoL (patients with a respiratory disease had up to 21.3% worse HRQoL than patients without a respiratory disease).Conclusion: The comprehensive management of patients with CHF should include the management of comorbidities which have been associated with a worse HRQoL, with special emphasis on anemia and iron deficiency, mental and behavioral disorders, diabetes mellitus, and respiratory diseases. An adequate control of these comorbidities may have a positive impact on the HRQoL of patients. [ABSTRACT FROM AUTHOR]

DJ-1 is a redox-sensitive chaperone with reported antioxidant and anti-inflammatory properties in the kidney. The 20 amino acid (aa) peptide ND-13 consists of 13 highly conserved aas from the DJ-1 sequence and a TAT-derived 7 aa sequence that helps in cell penetration. This study aimed to determine if ND-13 treatment prevents the renal damage and inflammation associated with unilateral ureter obstruction (UUO). Male C57Bl/6 and DJ-1−/− mice underwent UUO and were treated with ND-13 or vehicle for 14 days. ND-13 attenuated the renal expression of fibrotic markers TGF-β and collagen1a1 (Col1a1) and inflammatory markers TNF-α and IL-6 in C57Bl/6 mice. DJ-1−/− mice treated with ND-13 presented similar decreased expression of TNF-α, IL-6 and TGF-β. However, in contrast to C57Bl/6 mice, ND-13 failed to prevent renal fibrosis or to ameliorate the expression of Col1a1 in this genotype. Further, UUO led to elevated urinary levels of the proximal tubular injury marker neutrophil gelatinase-associated lipocalin (NGAL) in DJ-1−/− mice, which were blunted by ND-13. Our results suggest that ND-13 protects against UUO-induced renal injury, inflammation and fibrosis. These are all crucial mechanisms in the pathogenesis of kidney injury. Thus, ND-13 may be a new therapeutic approach to prevent renal diseases. [ABSTRACT FROM AUTHOR]

Background: Cerebrovascular diseases are the second leading cause of death worldwide and one of the health conditions which demand the highest level of social services. The aim of this study was to estimate the social cost of non-professional (informal) care provided to survivors of cerebrovascular accidents (CVA) with some type of disability in Spain.Methods: We obtained data from the 2008 Survey on Disability, Independent Living and Dependency (EDAD-08) on the main characteristics of individuals who provide informal care to survivors of CVAs in Spain. We estimated the cost of substituting informal care in favor of formal care provided by professional caregivers (proxy good method) and performed a statistical analysis of the relationship between degree of dependency and number of care hours provided using ordinary least squares regression.Results: The number of disabled people diagnosed with CVA totaled 1,975 (329,544 people when extrapolating to the national population using the elevation factor provided by EDAD-08). Of these, 1,221 individuals (192,611 people extrapolated to the national population) received at least one hour of informal care per week. The estimated hours of informal care provided in 2008 amounted to 852 million. The economic valuation of the time of informal care ranges from 6.53 billion euros (at 7.67 euros/hour) to 10.83 billion euros (when calculating each hour of care at 12.71 euros). The results of our statistical analysis highlight the importance of degree of dependency in explaining differences in the number of hours of informal care provided.Conclusions: The results of our study reveal the high social cost of cerebrovascular accidents in Spain. In addition, evidence is presented of a correlation between higher degree of dependency in CVA survivors and greater number of hours of care received. An integral approach to care for CVA survivors requires that the caregivers' role and needs be taken into account. [ABSTRACT FROM AUTHOR]
