Next-generation X-ray satellite telescopes such as XRISM, NewAthena and Lynx will enable observations of exotic astrophysical sources at unprecedented spectral and spatial resolution. Proper interpretation of these data demands that the accuracy of the models is at least within the uncertainty of the observations. One set of quantities that might not currently meet this requirement is transition energies of various astrophysically relevant ions. Current databases are populated with many untested theoretical calculations. Accurate laboratory benchmarks are required to better understand the coming data. We obtained laboratory spectra of X-ray lines from a silicon plasma at an average spectral resolving power of $\sim$7500 with a spherically bent crystal spectrometer on the Z facility at Sandia National Laboratories. Many of the lines in the data are measured here for the first time. We report measurements of 53 transitions originating from the K-shells of He-like to B-like silicon in the energy range between $\sim$1795 and 1880 eV (6.6–6.9 Å). The lines were identified by qualitative comparison against a full synthetic spectrum calculated with ATOMIC. The average fractional uncertainty (uncertainty/energy) for all reported lines is ${\sim}5.4 \times 10^{-5}$. We compare the measured quantities against transition energies calculated with RATS and FAC as well as those reported in the NIST ASD and XSTAR’s uaDB. Average absolute differences relative to experimentally measured values are 0.20, 0.32, 0.17 and 0.38 eV, respectively. All calculations/databases show good agreement with the experimental values; NIST ASD shows the closest match overall.
The Romans were among the first societies to extensively exploit fish resources, establishing large-scale salting and preservation plants where small pelagic fish were fermented to produce sauces such as garum. Here, the authors demonstrate that, despite being crushed and exposed to acidic conditions, usable DNA can be recovered from ichthyological residues at the bottom of fish-salting vats. At third-century AD Adro Vello (O Grove), Galicia, they confirm the use of European sardines (Sardina pilchardus) and move beyond morphology to explore population range and admixture and reveal the potential of this overlooked archaeological resource.
Effective participation of individuals with disabilities in health technology assessment (HTA) processes is paramount. Aware of the reality of people with physical and organic disabilities, COGAMI (a not-for-profit umbrella organization of disability associations) conducted an internal study to gather perspectives on the participation of people with disabilities in HTA processes.
Methods
An ad hoc questionnaire of four open-ended questions was designed and distributed via email to COGAMI’s socio-health commission, representing 23 entities and 4,000 people in Galicia. A thematic analysis of the responses obtained was carried out.
Results
Consensus underscores the fundamental role of individuals with disabilities and their representative organizations in HTA processes, though currently, only those with greater resources actively participate. The participants found that insufficient information reaching patient organizations hinders participation (e.g., lack of awareness in proposal submission), complicating their involvement. Additional challenges include accessibility and the digital divide. Proposed solutions involve enhancing communication channels and information accessibility, establishing collaborative frameworks nationally, and actively considering the disability condition to ensure a fair and equitable implementation.
Conclusions
This study suggests the need for concrete actions to enhance the participation of individuals with disabilities in HTA processes. Recommendations include improving communication channels, capacity building, and recognizing disability as a key element in HTA.
Patient engagement in the health technology assessment (HTA) field is crucial but faces significant challenges. This study focuses on identifying the barriers and facilitators surrounding the incorporation of patients in HTA while proposing solutions from the perspective of the Patient Interest Group (GIP) within the Spanish Network of Agencies for Health Technology Assessment and Services of the National Health System (RedETS).
Methods
An ad hoc questionnaire with four open-ended questions about barriers, facilitators, and proposals was developed and distributed among the GIP members through an email survey methodology. The obtained results were discussed in an open in-person meeting, and a thematic analysis of the data was conducted.
Results
Fifteen people answered the questionnaire (at least one HTA researcher from each agency), and forty people participated in the face-to-face discussion. Main barriers included the perception of a lack of institutional support, insufficient participative culture, lack of time and experience, and difficulties in planning. Facilitators included activities organized within the GIP and methodological procedures and documents published. The main proposals for improvement were focused on the training and capacity building of HTA researchers and patients, institutional commitment to patient involvement, promotion of forums and activities with patient entities, and improvement of communication channels with patients and dissemination.
Conclusions
Despite current challenges in patient involvement, this study highlights facilitators and proposals for improvement. Specialized training and education, along with the promotion of a participative culture, emerge as relevant strategies.
The participation of people with mental health conditions or patient representatives is of relevance in the health technology assessment (HTA) field, although there are some challenges that need to be considered. This study was designed to gain the perspectives of patient representatives with experience participating in HTA projects, with the aim of delving into the main issues and proposing ideas for the future.
Methods
A structured interview, based on five open-ended questions, was formulated and distributed via email. Five patient representatives from the Saúde Mental FEAFES Galicia (the Federation of Associations of Family Members and Persons with Mental Illness of Galicia, Spain) who had actively engaged in HTA projects over the past five years participated in the study. The collected data were analyzed using thematic analysis.
Results
Participants underscored the pivotal role of involving persons with mental health conditions and their representatives in HTA and emphasized the importance of knowing their perspectives, preferences, and values. Challenges included the complexity of HTA reports and processes, in terms of length and the technical language used, and socioeconomic barriers. Proposed solutions included material adaptation, streamlined processes, and institutional and professional support. Future recommendations emphasized improving awareness, disseminating the HTA field, fostering active participation, and emphasizing the relevance of participating in the HTA process. Of particular significance was the encouragement of training and capacity building among patients with mental health conditions.
Conclusions
This study reveals the need to strengthen and facilitate the participation of individuals with mental health conditions in HTA processes, and emphasizes the importance of knowing their perspectives, preferences, and values. Recommendations include training and capacity building, simplifying materials and processes, and providing adequate support.
This study aims to outline Clostridioides difficile infection (CDI) trends and outcomes in Mexican healthcare facilities during the COVID-19 pandemic.
Design:
Observational study of case series.
Setting:
Sixteen public hospitals and private academic healthcare institutions across eight states in Mexico from January 2016 to December 2022.
Patients:
CDI patients.
Methods:
Demographic, clinical, and laboratory data of CDI patients were obtained from clinical records. Cases were classified as community or healthcare-associated infections, with incidence rates calculated as cases per 10,000 patient days. Risk factors for 30-day all-cause mortality were analyzed by multivariate logistic regression.
Results:
We identified 2,356 CDI cases: 2,118 (90%) were healthcare-associated, and 232 (10%) were community-associated. Common comorbidities included hypertension, diabetes, and cancer. Previous high use of proton-pump inhibitors, steroids, and antibiotics was observed. Recurrent infection occurred in 112 (5%) patients, and 30-day mortality in 371 (16%). Risk factors associated with death were a high Charlson score, prior use of steroids, concomitant use of antibiotics, leukopenia, leukocytosis, elevated serum creatine, hypoalbuminemia, septic shock or abdominal sepsis, and SARS-CoV-2 coinfection. The healthcare-associated CDI incidence remained stable at 4.78 cases per 10,000 patient days during the pre-and pandemic periods. However, the incidence was higher in public hospitals.
Conclusions:
Our study underscores the need for routine epidemiology surveillance and standardized CDI classification protocols in Mexican institutions. Though CDI rates in our country align with those in some European countries, disparities between public and private healthcare sectors emphasize the importance of targeted interventions.
Health technology assessment (HTA) bodies support healthcare decision-making by producing different kind of products. The high speed of the healthcare innovations and the scenarios such as the COVID-19 pandemic challenge HTA organizations to adapt their services to better respond to these demands. The Spanish Network of HTA Agencies (RedETS) is redefining the services and the products in its portfolio. The first step has been conducting a review in order to identify the most relevant HTA products.
Methods
A scoping review with two sections was conducted: (i) analysis of results from a bibliographic search performed in the main biomedical databases; and (ii) analysis of results from a manual review of the official websites of seven international HTA agencies: CADTH (Canada), INESSS (Canada), SBU (Sweden), NICE (United Kingdom), IQWIG (Germany), HAS (France), IECS (Argentina) and IETS (Colombia). The EUnetHTA website was also reviewed.
Results
The search identified 1,311 references; 21 studies were considered relevant. The main topic found was about rapid responses services. The standard timeline for these should be less than six months, with even some produced in days. Transparency about methodology and involvement of decision-makers were considered key points to be included. Website analysis revealed similar HTA reports production but variation in the domains and elements considered. The timeframe for conducting a full HTA report can be up to 24 months, with a median of 12 months. Agencies also offer some kinds of rapid response services. Scientific consultation and horizon scanning systems for emerging technologies are other services performed by some agencies.
Conclusions
The review reveals that agencies have different products to address different needs throughout the life cycle of technologies: from scientific advice to full HTA. In addition, HTA agencies have incorporated rapid responses into their services. According to literature, these products could support short-term decision-making.
The Patient Involvement (PI) Interest Group of the Spanish Network of Health Technology Assessment Agencies (RedETS) was set up in 2017 by a group of health technology assessment (HTA) researchers interested in PI. Since its inception, training and capacity-building to support PI and patient-based evidence in HTA processes has been one of its main aims. The objective of this work was to identify the needs and priorities related to training and capacity building activities to be developed within the framework of the PI Interest Group.
Methods
The PI Interest Group met on November 14, 2022, for its Annual Meeting. The group discussed the needs, priorities and possibilities on training, and carried out a prioritization exercise. For this purpose, a self-reported and anonymous questionnaire was used, which included 16 training activities. Every item was scored with a Likert-type scale ranging from 0 to 10.
Results
The questionnaire was answered by twenty participants. The most highly rated training activities (mean less than or equal to 8) were: qualitative evidence synthesis (8.75); PI case studies (basic (8.65) and advanced (8.56) level); quality assessment tools for qualitative evidence (8.37); and qualitative research (8.11). Other proposals scoring above 7 points were: ethical aspects related to PI, evaluation of patient participation and impact, identification and recruitment procedures, and discrete choice experiments. The group agreed to organize bi-monthly webinars and three structured training activities for the whole RedETS network on: Qualitative Evidence Synthesis, Qualitative Research and PI Case Studies.
Conclusions
The prioritization of training activities according to PI Interest Group members allowed planning a tailored capacity-building program adapted to the needs of RedETS.
Health technology assessment (HTA) agencies in Spain have an important role in informing decisions about the introduction and use of health technologies in the Spanish National Health System. However, although different approaches have been taken to measure and improve their impact, no study to date has explored the perceived impact of HTA products at the national level. The aim of this study was to explore the perspectives of macro-, meso-, and micro-level decision makers on how to improve the impact of HTA.
Methods
Three online focus groups were conducted with policy makers, healthcare managers, clinicians, and patients. The transcripts were evaluated using a deductive thematic analysis based on a multidimensional framework to explore mechanisms of impact.
Results
Four key themes were identified:
(i) Timeliness and use of HTA assessments: Although the quality of the reports was recognized, the time taken for the elaboration and extension of reports negatively affected their use. Participants considered that reports should be tailored to the needs of end users (e.g., briefer versions available for meso-and micro-level use);
(ii) Effective engagement and external communications: The engagement of multiple stakeholders (policy makers, manufacturers, clinicians, and patients) in the elaboration process was considered crucial to improve HTA impact and ensure adequate communication of results;
(iii) Good institutional reputation and fit within the healthcare and policy making system: Stakeholders agreed on the need to strengthen collaboration at the national level and increase public understanding of the value of HTA and its use in healthcare decision-making; and
(iv) Effective implementation of policy change regarding health technologies: Stakeholders were very receptive to the results and recommendations of HTA reports when new technologies are demanded, but the identification and selection process should be improved to guarantee that these reports are available on time.
Conclusions
This study has identified different proposals and mechanisms that could improve the impact of HTA in Spain.
Patient-reported outcome measures are being increasingly considered both in clinical practice and in the field of health technology assessment. Although emotional distress is currently recognized as the sixth vital sign in cancer care, its early detection and screening is not yet included in routine clinical practice in Spain. The main objective of this study was to assess the psychometric properties and diagnostic accuracy of validated tools for the early detection of distress among adults with cancer in the Spanish context, at the request of the Spanish National Health System (NHS) Cancer Strategy.
Methods
A systematic review was carried out to analyze development and validation studies. The Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2) was used for the risk of bias assessment, and a multicriteria global assessment was used for the tests. Ethical and organizational aspects were also addressed.
Results
Fifteen validation studies were included, corresponding to seven tests. The tools considered were the Distress Thermometer (DT), the Brief Symptom Inventory-18 (BSI-18), the Edmonton Symptom Assessment System-revised (ESAS-r), the Hospital Anxiety and Depression Scale (HADS), the Visual Analog Scale for Anxiety and Depression (VAS-AD), the Detection of Emotional Distress (DED) scale, and the Psychosocial and Spiritual Needs Evaluation (ENP-E) scale. Evidence of validity, reliability (internal consistency), and diagnostic accuracy (sensitivity, specificity, and area under the receiver operating characteristic curve) were summarized. Three scales were rated as poor (VAS-AD, BSI-18, and ESAS-r), the ENP-E scale was rated as acceptable, and three scales were rated as moderate (DT, DED, and HADS).
Conclusions
The DT (single-item measure) stands out as an appropriate tool for early detection of emotional distress in the Spanish NHS. The use of this scale could be considered a first stage, to be combined later with a longer scale to improve screening specificity. The HADS scale could be utilized for this purpose. The use of these tools should be framed within a structured screening program that ensures further evaluation and subsequent psychological care when needed.
Front-of-package warning labels introduced in Mexico in 2020 included disclaimers that caution against allowing children to consume products with non-sugary sweeteners and caffeine. We examined the awareness and use of the disclaimers among Mexican adults and youth 1 month after the regulation was implemented. We also investigated their impact on the perceived healthfulness of industrialised beverages designed for children.
Design:
Data on the awareness and use of the disclaimers were analysed. Two between-subjects experiments examined the effect of a sweetener disclaimer (Experiment 1, youth and adults) or a caffeine disclaimer (Experiment 2, only adults) on the perceived healthfulness of industrialised beverages. Interactions between experimental conditions and demographic characteristics were tested.
Setting:
Online survey in 2020.
Participants:
Mexican adults (≥18 years, n 2108) and youth (10–17 years, n 1790).
Results:
Most participants (>80 %) had seen the disclaimers at least rarely, and over 60 % used them sometimes or frequently. The sweetener disclaimer led to a lower perceived healthfulness of a fruit drink (adults: 2·74 ± 1·44; youth: 2·04 ± 0·96) compared with the no-disclaimer condition (adults: 3·17 ± 1·54; youth: 2·32 ± 0·96) (t’s: >4·0, P values: <0·001). This effect was larger among older adults and male youth. The caffeine disclaimer did not affect adult’s perceived healthfulness of a caffeinated drink (t = 0·861, P value = 0·3894).
Conclusions:
There were high awareness and use of the sweeteners and caffeine disclaimers shortly after the warning labels were implemented. The sweetener disclaimer appears to be helping consumers modify their perceptions regarding industrialised beverages for children. Findings may help decision-makers improve the regulation and better target communication strategies.
The coronavirus disease 2019 (COVID-19) has serious physiological and psychological consequences. The long-term (>12 weeks post-infection) impact of COVID-19 on mental health, specifically in older adults, is unclear. We longitudinally assessed the association of COVID-19 with depression symptomatology in community-dwelling older adults with metabolic syndrome within the framework of the PREDIMED-Plus cohort.
Methods
Participants (n = 5486) aged 55–75 years were included in this longitudinal cohort. COVID-19 status (positive/negative) determined by tests (e.g. polymerase chain reaction severe acute respiratory syndrome coronavirus 2, IgG) was confirmed via event adjudication (410 cases). Pre- and post-COVID-19 depressive symptomatology was ascertained from annual assessments conducted using a validated 21-item Spanish Beck Depression Inventory-II (BDI-II). Multivariable linear and logistic regression models assessed the association between COVID-19 and depression symptomatology.
Results
COVID-19 in older adults was associated with higher post-COVID-19 BDI-II scores measured at a median (interquartile range) of 29 (15–40) weeks post-infection [fully adjusted β = 0.65 points, 95% confidence interval (CI) 0.15–1.15; p = 0.011]. This association was particularly prominent in women (β = 1.38 points, 95% CI 0.44–2.33, p = 0.004). COVID-19 was associated with 62% increased odds of elevated depression risk (BDI-II ≥ 14) post-COVID-19 when adjusted for confounders (odds ratio; 95% CI 1.13–2.30, p = 0.008).
Conclusions
COVID-19 was associated with long-term depression risk in older adults with overweight/obesity and metabolic syndrome, particularly in women. Thus, long-term evaluations of the impact of COVID-19 on mental health and preventive public health initiatives are warranted in older adults.
Image-processing pipelines require the design of complex workflows combining many different steps that bring the raw acquired data to a final result with biological meaning. In the image-processing domain of cryo-electron microscopy single-particle analysis (cryo-EM SPA), hundreds of steps must be performed to obtain the three-dimensional structure of a biological macromolecule by integrating data spread over thousands of micrographs containing millions of copies of allegedly the same macromolecule. The execution of such complicated workflows demands a specific tool to keep track of all these steps performed. Additionally, due to the extremely low signal-to-noise ratio (SNR), the estimation of any image parameter is heavily affected by noise resulting in a significant fraction of incorrect estimates. Although low SNR and processing millions of images by hundreds of sequential steps requiring substantial computational resources are specific to cryo-EM, these characteristics may be shared by other biological imaging domains. Here, we present Scipion, a Python generic open-source workflow engine specifically adapted for image processing. Its main characteristics are: (a) interoperability, (b) smart object model, (c) gluing operations, (d) comparison operations, (e) wide set of domain-specific operations, (f) execution in streaming, (g) smooth integration in high-performance computing environments, (h) execution with and without graphical capabilities, (i) flexible visualization, (j) user authentication and private access to private data, (k) scripting capabilities, (l) high performance, (m) traceability, (n) reproducibility, (o) self-reporting, (p) reusability, (q) extensibility, (r) software updates, and (s) non-restrictive software licensing.
Primary health care (PHC) professionals may play a crucial role in improving early diagnosis of depressive disorders. However, only 50% of cases are detected in PHC. The most widely used screening instrument for major depression is the Patient Health Questionnaire (PHQ), including the two-, eight- and nine-item versions. Surprisingly, there is neither enough evidence about the validity of PHQ in PHC patients in Spain nor indications about how to interpret the total scores. This study aimed to gather validity evidence to support the use of the three PHQ versions to screen for major depression in PHC in Spain. Additionally, the present study provided information for helping professionals to choose the best PHQ version according to the context.
Methods
The sample was composed of 2579 participants from 22 Spanish PHC centers participating in the EIRA-3 study. The reliability and validity of the three PHQ versions for Spanish PHC patients were assessed based on responses to the questionnaire.
Results
The PHQ-8 and PHQ-9 showed high internal consistency. The results obtained confirm the theoretically expected relationship between PHQ results and anxiety, social support and health-related QoL. A single-factor solution was confirmed. Regarding to the level of agreement with the CIDI interview (used as the criterion), our results indicate that the PHQ has a good discrimination power. The optimal cut-off values were: ⩾2 for PHQ-2, ⩾7 for PHQ-8 and ⩾8 for PHQ-9.
Conclusions
PHQ is a good and valuable tool for detecting major depression in PHC patients in Spain.
Type 2 diabetes mellitus (T2DM) is characterised by chronic hyperglycaemia. Despite the efficacy of conventional pharmacotherapy, some individuals do not reach glycaemic goals and require adjuvant therapies. Taurine, a semi-essential amino acid, decreases blood glucose and cholesterol levels in rodents and humans. However, glycated hemoglobin (HbA1c) has not been evaluated in randomised controlled trials after taurine treatment for more than 12 weeks. This study aims to evaluate the effect of taurine administration on glycaemic, lipid, inflammatory, anthropometric and dietary parameters in individuals with T2DM. A randomised, double-blind, placebo-controlled clinical trial will be conducted at the Clinical Research Center of a tertiary public hospital. Participants with T2DM (n 94) will be recruited and randomised to receive 3 g of taurine or placebo, twice/day, orally, for 12 weeks. Blood samples will be collected before and after 12 weeks of treatment, when HbA1c, fasting glucose, insulin, albuminuria, creatinine, total cholesterol and fractions, triglycerides, C-reactive protein, TNF-α, IL 1, 4, 5, 6, 10 and 13 will be evaluated. Anthropometric parameters and 24-hour food recall will also be evaluated. The study will evaluate the effect of taurine treatment on biochemical and anthropometric parameters in individuals with T2DM. These results will guide the decision-making to indicate taurine treatment as an adjunct in individuals with T2DM who have not reached their glycaemic goal.
Postpartum depression (PPD) is one of the most common disorders following childbirth. This systematic review and meta-analysis (SR/MA) aimed to assess the effectiveness of psychological interventions in preventing PPD in non-depressed women. PRISMA guidelines were followed. MEDLINE (Ovid and PubMed), PsycINFO, Web of Science, Scopus, CINAHL, CENTRAL, OpenGrey, Australian New Zealand Clinical Trial Registry and clinicaltrial.gov were searched. Randomized controlled trials (RCTs) conducted with pregnant or postpartum (up to 12 months) women who were non-depressed at baseline were selected. The outcomes were the incidence of PPD and/or the reduction of postpartum depressive symptoms. The standardized mean difference (SMD) using random-effect models was calculated. Sensitivity, sub-group and meta-regression analyses were performed. 17 RCTs were included in the SR and 15 in the MA, representing 4958 participants from four continents. The pooled SMD was −0.175 [95% confidence interval (CI) −0.266 to −0.083; p < 0.001] and sensitivity analyses confirmed the robustness of this result. Heterogeneity was low (I2 = 21.20%) and was fully explained by a meta-regression model including one variable (previous deliveries). The meta-regression model and MA stratified by previous deliveries indicated that interventions focused on primiparous women are more effective. There was no evidence of publication bias. Few RCTs had an overall low risk of bias. According to GRADE, the quality of evidence was moderate. Psychological interventions have very little effectiveness in preventing PPD in non-depressed women, although this effectiveness is greater in interventions focused on primiparous women. Further RCTs with a low risk of bias and more effective interventions are needed.
We record for the first time a nominal species of the genus Microscleroderma in the Western Atlantic, and the first record of the genus Amphibleptula in Mexico. Two new species of ‘lithistid’ Tetractinellida are described: Microscleroderma mexica sp. nov. from crevices of two reefs in Veracruz, Mexico, and Amphibleptula aaktun sp. nov. from the anchialine cave El Aerolito, Cozumel Island, Mexico. Microscleroderma mexica sp. nov. is characterized by its tubular and cup-shaped to wavy laminar habitus, hirsute surface and two size categories of oxea diactines. Amphibleptula aaktun sp. nov. is characterized by its ficiform or lobular habitus with an exhalant area at the flat top of the body, divided into numerous vertical septa-like structures; its desmas have thinner epirhabds, and thinner oxea than those of Amphibleptula madrepora. This is the second species of Amphibleptula that has been described; hence, we propose the redefinition of the genus. Both species described have a shallow distribution (≤21 m depth); they are differentiated from each other by the disjunction between their habitats as well as by their morphology.
Identify and characterise the food industry’s involvement in nutrition and dietetics national and regional events in Latin America and the Caribbean.
Design:
Between February and April 2020, we conducted desk-based searches for nutrition and dietetics events held in the region between January 2018 and December 2019. Online freely accessible, publicly available information was collected on the involvement of the food industry through: sponsorship of events; sponsorship of sessions; speakers from the food industry; scholarships, fellowship, grants, awards and other prizes and; exhibition space/booths.
Setting:
Nutrition and dietetics events in Latin America and the Caribbean.
Results:
Thirty-one events held in twenty countries of the region had information publicly available online at the period of data collection. There was a lack of transparency on the involvement of industry actors in these events. When information was publicly available, we found that a total of ninety-two food industry actors sponsored 88 % of these events.
Conclusions:
There is a mostly unreported, but likely extensive, involvement of food industry actors in nutrition and dietetics events in Latin America and the Caribbean.
