Primary Health Care Case-Management Nurses during the COVID-19 Pandemic: A Qualitative Study.

The COVID-19 has caused high morbidity and mortality in vulnerable people, such as those affected by chronic diseases, and case-management nurses (CMNs) are reference professionals for their health care and management. The objective of this study is to better understand the discourse, experiences, and feelings about the professional performance of CMNs during the pandemic. A qualitative study was conducted by conducting semi-structured interviews with CMNs (n = 31) from the province of Seville (Spain) and performing a narrative discourse analysis. The Atlas Ti 6.2 software program was used. Two categories were defined: 1. CMNs' competencies (76 verbatim testimonies); and 2. Consequences of the COVID-19 pandemic (61 verbatim testimonies). This study was granted due permission by the Research Ethics Committee belonging to the University of Seville, under protocol code: 1139-N-22. The pandemic caused an increase in CMNs' workload, and they had to assume their usual care tasks for vulnerable populations in addition to simultaneously prioritizing assistance in nursing homes. We can highlight CMNs' adaptation to the pandemic situation and to these new requirements in the context of their significant social commitment to the advanced practice of the profession, a commitment that is closely related to leadership. We should also indicate that interpersonal relationships were improved, and that there was technological progress. Some CMNs mentioned an increase in their workload and reported experiencing burnout syndrome. We conclude that CMNs' management of health care during the pandemic has been extraordinary, especially in regard to the most vulnerable populations of patients, including individuals with chronic diseases and institutionalized older adults, a fact that has been valued by the institutions and by society in general.

[Effectiveness of interventions to help mitigate the influence of social networks on anorexia and bulimia nervosa: a systematic review].

BACKGROUND: The study aim to analyze the impact of interventions to help mitigate the influence of social networks on anorexia and bulimia nervosa. METHODOLOGY: A systematic review was conducted using PubMed, Scopus, PsycINFO and Web of Science. The inclusion criteria were: randomized clinical trials, published between 2013 and 2023 with a score = 5 points on the Van Tulder methodological quality scale. RESULTS: Eight studies were selected, most carried out in secondary education centers or universities; one was online. The study sample consisted of 5,084 participants mainly young women and adolescents with an average age between 12 and 32 years. As for the social networks, some studies described their impact at a general level, while others focused on Instagram, Facebook, Tik-Tok, Twitter, and Snapchat. A positive correlation was found between the exposure to unrealistic beauty ideals found in social networks with greater concern and dissatisfaction with body image. All studies used instruments to assess the effectiveness of the interventions. The interventions helped reduce the influence of the media and social networks, improve self-perception and self-esteem assessments, reduce anxiety levels and internalization of the thin beauty ideal, reduce dietary restrictions, and make use of social networks differently. CONCLUSIONS: Longer-lasting interventions can improve body satisfaction (one year) and depressive symptoms (six months), especially in women. Interventions should include attention to self-criticism, self-perception, self-esteem, body image, nutritional management, and media literacy skills.

Machine Learning-Based Prediction of Changes in the Clinical Condition of Patients With Complex Chronic Diseases: 2-Phase Pilot Prospective Single-Center Observational Study.

BACKGROUND: Functional impairment is one of the most decisive prognostic factors in patients with complex chronic diseases. A more significant functional impairment indicates that the disease is progressing, which requires implementing diagnostic and therapeutic actions that stop the exacerbation of the disease. OBJECTIVE: This study aimed to predict alterations in the clinical condition of patients with complex chronic diseases by predicting the Barthel Index (BI), to assess their clinical and functional status using an artificial intelligence model and data collected through an internet of things mobility device. METHODS: A 2-phase pilot prospective single-center observational study was designed. During both phases, patients were recruited, and a wearable activity tracker was allocated to gather physical activity data. Patients were categorized into class A (BI≤20; total dependence), class B (2060; moderate or mild dependence, or independent). Data preprocessing and machine learning techniques were used to analyze mobility data. A decision tree was used to achieve a robust and interpretable model. To assess the quality of the predictions, several metrics including the mean absolute error, median absolute error, and root mean squared error were considered. Statistical analysis was performed using SPSS and Python for the machine learning modeling. RESULTS: Overall, 90 patients with complex chronic diseases were included: 50 during phase 1 (class A: n=10; class B: n=20; and class C: n=20) and 40 during phase 2 (class B: n=20 and class C: n=20). Most patients (n=85, 94%) had a caregiver. The mean value of the BI was 58.31 (SD 24.5). Concerning mobility aids, 60% (n=52) of patients required no aids, whereas the others required walkers (n=18, 20%), wheelchairs (n=15, 17%), canes (n=4, 7%), and crutches (n=1, 1%). Regarding clinical complexity, 85% (n=76) met patient with polypathology criteria with a mean of 2.7 (SD 1.25) categories, 69% (n=61) met the frailty criteria, and 21% (n=19) met the patients with complex chronic diseases criteria. The most characteristic symptoms were dyspnea (n=73, 82%), chronic pain (n=63, 70%), asthenia (n=62, 68%), and anxiety (n=41, 46%). Polypharmacy was presented in 87% (n=78) of patients. The most important variables for predicting the BI were identified as the maximum step count during evening and morning periods and the absence of a mobility device. The model exhibited consistency in the median prediction error with a median absolute error close to 5 in the training, validation, and production-like test sets. The model accuracy for identifying the BI class was 91%, 88%, and 90% in the training, validation, and test sets, respectively. CONCLUSIONS: Using commercially available mobility recording devices makes it possible to identify different mobility patterns and relate them to functional capacity in patients with polypathology according to the BI without using clinical parameters.

Perceptions, Beliefs, and Experiences about the Menstrual Cycle and Menstruation among Young Women: A Qualitative Approach.

The experience of menstruation is often associated with negative connotations and gender stereotypes, which results in making it invisible. This research aimed to explore the perceptions, beliefs, and knowledge of young Spanish women regarding the menstrual cycle and menstruation and their impact on their lives. The study delves into their understanding, menstrual management practices, the types of menstrual products employed, and their experiences related to menstrual health. Qualitative methodology was used with discussion groups as a data collection technique. The participants comprised 45 young Spanish women, aged between 18 and 23, hailing from both rural and urban areas. The majority were university students, with some engaged in part-time work, and one participant working full-time. While many experienced menstrual pain ranging from mild to debilitating, a normalization of this pain often led them to forego seeking specialist assistance. Disposable menstrual products (DMPs) are the most used by participants, despite limited awareness of their absorption capacity. Regarding reusable menstrual products (RMPs), menstrual cup users emphasized comfort but expressed a need for proper training. Negative menstruation experiences could evoke fear and difficulties, underscoring the importance of providing comprehensive menstrual health education encompassing both theoretical and practical components.

Epidemiological differences, clinical aspects, and short-term prognosis of patients with healthcare-associated and community-acquired infective endocarditis.

Background: The prevalence of healthcare-associated infective endocarditis in Brazil is poorly known. Aim: To analyze the epidemiological, clinical and microbiological characteristics, and the prognosis of healthcare-associated infective endocarditis (HAIE) compared with community-acquired infective endocarditis (CIE) and identify the associated factors with hospital mortality. Method: A historical cohort study was carried out, with a data collection period from January 2009 to December 2019 at the Federal University of São Paulo. Data were collected from medical records of patients with infective endocarditis (IE) hospitalized during the study period. Patients were classified into three groups: CIE, non-nosocomial HAIE (NN-HAIE) and nosocomial HAIE (NHAIE). Results: A total of 204 patients with IE were included; of these, 127 (62.3%) were cases of HAIE, of which 83 (40.7%) were NN-HAIE and 44 (21.6%) were NHAIE. Staphylococcus spp. Were the main causative agents, especially in HAIE groups (P<0.001). Streptococcus spp. were more prevalent in the CIE group (P<0.001). In-hospital mortality was 44.6%, with no differences between groups. Independent risk factors for in-hospital mortality were age ≥ 60 years (odds ratio (OR): 6.742), septic shock (OR 5.264), stroke (OR 3.576), heart failure (OR 7.296), and Intensive Care Unit admission (OR 7.768). Conclusion: HAIE accounted for most cases in this cohort, with a higher prevalence of non-nosocomial infections. Staphylococcus spp. were the main causative agents. Hospital mortality was high, 44.6%, with no difference between groups.

Validity and Reliability of the Portuguese Version of the Connor-Davidson Resilience Scale of 10 Elements for Young University Students.

BACKGROUND: Resilience is an important aspect of mental health in young people, which has become more relevant after the COVID-19 pandemic. It is therefore of paramount importance to have valid and reliable instruments that measure the globality of this aspect. One of the instruments that has been shown to have good psychometric properties and which has been widely adapted in several languages is the Connor-Davidson resilience scale, composed of 10 elements (10-item CD-RISC). AIM: The aim of this study was to evaluate the validity and reliability of the Portuguese version of the 10-item CD-RISC among young university students. METHODS: a cross-sectional observational study of psychometric validation was conducted with a sample of 206 university students. RESULTS: Good and adequate fit indices were obtained for the confirmatory factor analysis (CFA): Standardized Root-Mean-Square Residual [SRMR] = 0. 056; comparative fit index [CFI] = 0.958; and the Tucker-Lewis index [TLI] = 0.946. It also showed an average degree of convergent validity with the Depression, Anxiety and Stress Scale (DASS-21) and the General Health Scale (SF-36), and its internal consistency was good (Cronbach's alpha = 0.842) with a range of factor loadings between 0.42 and 0.77. CONCLUSIONS: the results show that the 10-item CD-RISC is a valid, reliable scale to measure resilience among young Portuguese university students.

Evaluation of three commercial methods of susceptibility testing for ceftolozane/tazobactam against carbapenem-resistant Pseudomonas aeruginosa / Evaluación de 3 métodos comerciales de determinación de sensibilidad de ceftolozano/tazobactam frente a Pseudomonas aeruginosa resistente a las carbapenemas

Introduction: Ceftolozane/tazobactam has shown excellent activity against Pseudomonas aeruginosa, but this drug is not always included in commercial panels. The aim of the study was to evaluate the performance of 2 gradient strips (BioMérieux and Liofilchem) and a commercial microdilution panel (Sensititre, EURGNCOL panel) using this combination against carbapenem-resistant P. aeruginosa isolates. Methods: Three commercial methods were tested with 41 metallo-beta-lactamase-producing and 59 non-carbapenemase-producing P. aeruginosa isolates. Broth microdilution was used as reference. Results: All carbapenemase-producing isolates and only one non-producing isolate were resistant to this antibiotic. Both essential agreement and bias were outside the acceptance intervals since MIC values were higher than reference values for all three methods. The Kappa index indicated poor or weak agreement. Changes in clinical categories were observed in 3 isolates. Conclusions: The three methods yielded poor agreement with the reference. Despite the differences in MIC values, fewer than 3% involved category changes.(AU)

Introducción: La combinación ceftolozano/tazobactam ha mostrado una actividad excelente frente a Pseudomonas aeruginosa, pero este fármaco no siempre se incluye en los paneles comerciales. El objetivo de este estudio es evaluar el rendimiento de 2 tiras de gradiente (BioMérieux® y Liofilchem®) y un panel de microdilución comercial (Sensititre®, panel EURGNCOL) utilizando esta combinación frente a aislados de P. aeruginosa resistente a los carbapenémicos. Métodos: Se probaron 3 métodos comerciales con 41 aislados productores de metalobetalactamasas y 59 aislados no productores de carbapenemasas de P. aeruginosa. La microdilución de caldo se utilizó como referencia. Resultados: Todos los aislados productores de carbapenemasas y solo un aislado no productor fueron resistentes a este antibiótico. Tanto la concordancia esencial como el sesgo se encontraron fuera de los intervalos de aceptación, dado que los valores CMI eran superiores que los valores de referencia para los 3 métodos. El índice de Kappa indicó una concordancia pobre o débil. Se observaron cambios en las categorías clínicas en 3 aislados. Conclusiones: Los 3 métodos presentaron una baja concordancia con la microdilución de referencia. A pesar de las diferencias en los valores MIC, menos del 3% implicaron cambios de categoría.(AU)

Survival Impact of an On-Site Medicalization Program in the Control of COVID-19 Outbreaks in 11 Nursing Homes.

BACKGROUND: The elderly admitted to nursing homes have especially suffered the havoc of the COVID-19 pandemic since most of them are not prepared to face such health problems. METHODS: An innovative coordinated on-site medicalization program (MP) in response to a sizeable COVID-19 outbreak in three consecutive waves was deployed, sharing coordination and resources among primary care, the referral hospital, and the eleven residences. The objectives were providing the best possible medical care to residents in their environment, avoiding dehumanization and loneliness of hospital admission, and reducing the saturation of hospitals and the risk of spreading the infection. The main outcomes were a composite endpoint of survival or optimal palliative care (SOPC), survival, and referral to the hospital. RESULTS: 587 of 1199 (49%) residents were infected, of whom 123 (21%) died. Patients diagnosed before the start of the MP presented SOPC, survival, and referrals to the hospital of 83%, 74%, and 22.4%, opposite to 96%, 84%, and 10.6% of patients diagnosed while the MP was set up. The SOPC was independently associated with an MP (OR 3.4 [1.6-7.2]). CONCLUSION: During the COVID-19 outbreak, a coordinated MP successfully obtained a better rate of SOPC while simultaneously reducing the need for hospital admissions, combining optimal medical management with a more compassionate and humanistic approach in older people.

Influencia del índice de masa corporal en las técnicas de reproducción asistida / Influence of Body Mass Index on Assisted Reproductive Techniques

Objetivo: Analizar la relación entre el índice de Masa Corporal en mujeres y los resultados obtenidos en las técnicas de reproducción asistida. Método: Se llevó a cabo un diseño no experimental, transversal, descriptivo y correlacional, mediante un análisis de datos secundarios en varias clínicas de reproducción asistida en España. Se analizaron 3.273 historias clínicas de mujeres sometidas a fecundación in vitro entre 2015-2018. Se recogieron datos de filiación e inicio del tratamiento, datos antropométricos, antecedentes personales, enfermedades actuales, esterilidad primaria, esterilidad secundaria, así como los parámetros referentes a los resultados tras tratamiento de reproducción asistida. El análisis estadístico se realizó mediante el software SPSS-V19.0. Resultados: 798 mujeres (24,42%) tenían un IMC ≥25. Las mujeres con sobrepeso consiguieron un menor número de ovocitos recuperados y fecundados, así como menor número de embriones obtenidos. Las mujeres con peso normal consiguieron un menor número de óvulos maduros y las mujeres con bajo peso presentaron una menor tasa de fecundación. Conclusiones: Se ha encontrado que los resultados obtenidos en las técnicas de reproducción asistida tienen relación con el índice de Masa Corporal de las mujeres. (AU)

Objective: To analyze the relationship between the Body Mass Index in women and the results obtained in assisted reproductive techniques. Methods: A non-experimental, cross-sectional, descriptive and correlational design was carried out through an analysis of secondary data in several assisted reproduction clinics from Spain. 3,273 medical records of women undergoing In Vitro Fertilization between 2015 and 2018 were analyzed. Data on affiliation and treatment initiation, anthropometric data, personal history, current diseases, primary and secondary infertility, as well as the reference parameters to the results after the assisted reproduction treatment were collected. The statistical analysis was performed using SPSS v19.0 software. Results: A total of 798 women (24.42%) had a BMI values ≥ 25. The overweight women achieved a lower number of oocytes retrieved and fertilized, as well as fewer embryos obtained. The women with normal weight achieved a lower number of mature oocytes and those with low weight had a lower fertilization rate. Conclusions: It has been found that the results obtained in assisted reproductive techniques are related to women's Body Mass Index. (AU)

The Perceptions of Women with Gynecological Cancer after Radiotherapy Treatment: A Gender-Based Qualitative Study.

Gynecological cancer is on the rise and radiotherapy is resorted to for its treatment, which affects the patients. This study was conducted following qualitative methodology to analyze women's gender-based perceptions. The data were collected by means of semi-structured interviews. Five categories were defined: 1. feelings; 2. daily living activities; 3. role in the couple/family; 4. coping; and 5. knowledge and uncertainties. There was one emerging category: embarrassment and effects of toxicity. The qualitative data analysis was performed in Nudist NVivo V.11. It was concluded that the patients presented both positive and negative feelings, there were limitations to their daily living activities, their role in the couple/family was affected, they faced problems with resignation, emotional avoidance, and spirituality, they mostly stated having incomplete information, and they underwent uncomfortable situations due to the secondary effects of radiotherapy.

Feasibility of the Implementation of LESS-CHRON in Clinical Practice: A Pilot Intervention Study in Older Patients With Multimorbidity.

Background and Objectives: Potentially inappropriate medication refers to the prescription of drugs whose risks outweigh the benefits. There are different pharmacotherapeutic optimization strategies to detect and avoid potentially inappropriate medications (PIMs), namely deprescription. The List of Evidence-Based Deprescribing for Chronic Patients (LESS-CHRON) criteria were designed as a tool to systematize the deprescribing process. LESS-CHRON has established itself as one of the most suitable to be applied in older (≥65 years) multimorbid patients. However, it has not been applied to these patients, to measure the impact on their treatment. For this reason, a pilot study was conducted to analyze the feasibility of implementing this tool in a care pathway. Research Design and Methods: A pre-post quasi-experimental study was conducted. Older outpatients with multimorbidity from the Internal Medicine Unit of a benchmark Hospital were included. The main variable was feasibility in clinical practice, understood as the likelihood that the deprescribing intervention recommended by the pharmacist would be applied to the patient. Success rate, therapeutic, and anticholinergic burden, and other variables related to health care utilization were analyzed. Results: A total of 95 deprescribing reports were prepared. Forty-three were evaluated by the physician who assessed the recommendations made by pharmacists. This translates into an implementation feasibility of 45.3%. The application of LESS-CHRON identified 92 PIMs. The acceptance rate was 76.7% and after 3 months 82.7% of the stopped drugs remained deprescribed. A reduction in anticholinergic burden and enhanced adherence was achieved. However, no improvement was found in clinical or health care utilization variables. Discussion and Implications: The implementation of the tool in a care pathway is feasible. The intervention has achieved great acceptance and deprescribing has been successful in a not insignificant percentage. Future studies with a larger sample size are necessary to obtain more robust results in clinical and health care utilization variables.

"Compassionate City" in Patients with Advanced Illnesses and at the End of Life: A Pilot Study.

OBJECTIVES: To evaluate, in a Compassionate City pilot experience (Sevilla), the impact results on health in a population of people with advanced illness and at the end of life. METHODS: The project was undertaken in Sevilla, Spain, between January 2019 and June 2020. A longitudinal, descriptive study was conducted using a longitudinal cohort design with two cross-sectional measurements, pre and post intervention. All patients who entered the program on the start date were included. The networks of care around people with advanced illness and at the end of life, palliative care needs, quality of life, loneliness, anxiety, depression, caregivers' burden and family satisfaction were evaluated. The interventions were conducted by community promoters assigned to the "Sevilla Contigo, Compassionate City" program. RESULTS: A total of 83 people were included in the program. The average number of people involved in care at the beginning of the evaluations was 3.6, increasing to 6.1 at the end of the interventions. The average number of needs detected at the beginning was 15.58, and at the end of interventions, it was 16.56 out of 25. The unmet needs were those related to last wishes (40.7%), emotional relief (18.5%), entertainment (16%), help to walk up and down stairs (8.6%) and help to walk (6.2%). A total of 54.2% showed improved loneliness in the final evaluation. Out of 26 people evaluated for pre and post quality of life, 7 (26.9%) improved their quality of life in the general evaluation and 5 (19.2%) displayed improved anxiety/depression. A total of 6 people (28.6%) improved their quality-of-life thermometer scores. A total of 57.7% of caregivers improved their burden with a mean score of 17.8.

Quality of Life in Caregivers of Cancer Patients: A Literature Review.

(1) Background: Cancer constitutes one of the principal causes of morbi-mortality in the world and generates an important loss of patients' self-sufficiency. People who are their caregivers usually become the main care providers, which impacts their quality of life; (2) Aim: Analyze the different problems (physical, emotional, social, and financial) faced by people who are caregivers of adults with cancer and describe the strategies required to improve their quality of life; (3) Method: A literature review was conducted on the following database: PubMed, Cinahl, PsycINFO, and Scopus. The following eligibility criteria were specified: (a) research studies of quantitative, qualitative, or mixed methods, (b) consistent with objective, and (c) published in the English language or Spanish during the last five years; (4) Results: 36 studies were selected from those found in the literature. Regarding the problems mentioned: eight studies described physical issues, 26 emotional effects, 10 social implications, and seven financial strains. Twenty-eight studies described strategies to improve the quality of life of caregivers; (5) Conclusions: Caregivers are usually women around the age of 50. Problems faced are mostly emotional in nature, followed by social, physical, and financial ones. In order to cope with this burden, there are some strategies that can be developed to help to build skills to manage both the disease and the impact derived from it, therefore improving their quality of life.

Prevalence of Potentially Inappropriate Medications in Patients With Multimorbidity According to LESS-CHRON and STOPPFrail Criteria.

OBJECTIVE: LESS-CHRON (List of Evidence-Based Deprescribing for Chronic Patients) and STOPPFrail (Screening Tool of Older Persons' Prescriptions in Frail adults with limited life expectancy) are criterion-based deprescribing tools. This study aimed to identify the prevalence of potentially inappropriate medications (PIMs) with these tools in an outpatient, polymedicated, older population with multimorbidity. DESIGN: Single-center cross-sectional observational study. SETTING AND PARTICIPANTS: PIMs and criteria subject to deprescribing identified by each tool were collected in patients who were being followed up on outpatient internal medicine consultation. METHODS: PIMs were identified by STOPPFrail and LESS-CHRON criteria reviewing medical histories and pharmacologic treatments of the patients in the electronic health card system. Sociodemographic, clinical, and pharmacologic variables were recorded. A correlation analysis between treatment tools and clinical values was performed using the nonparametric Spearman rho correlation. RESULTS: Eighty-three patients with a median of 14.4 (interquartile range 12-17) prescribed drugs were included. The total number of PIMs identified with LESS-CHRON was 158 vs 127 with STOPPFrail. Eight of the 27 criteria (29.6%) for LESS-CHRON and 15 of the 25 for STOPPFrail were found to be not applicable. A significant correlation was obtained for both tools with the number of prescribed drugs at the time of inclusion. The Profund, Barthel, and Frail-VIG index only showed a significant correlation with LESS-CHRON. CONCLUSION AND IMPLICATIONS: Both tools have shown the capacity to identify PIMs that can be deprescribed in the population studied. However, LESS-CHRON appears to have a greater detection potential in the subgroup of patients analyzed. STOPPFrail brings a certain complementarity in other areas of therapy not covered by LESS-CHRON.

Expert Panel Consensus for Addressing Anti-VEGF Treatment Challenges of Diabetic Macular Edema in Spain.

Purpose: The treatment of diabetic macular edema (DME) has evolved rapidly in the past decade, highlighting the need to address the challenges of routine clinical practice decision-making through expert consensus agreements. Methods: After a literature review and discussion of real-world experience on DME management, a group of ten retina specialists agreed on a consensus of recommendations for the most appropriate management of DME patients using vascular endothelial growth factor inhibitors (anti-VEGF) in Spain. Results: The panel recommended early treatment initiation in DME patients with worse baseline visual acuity (VA) to maintain or improve outcome. For patients with good VA, an observation strategy was recommended, considering the presence of diabetic retinopathy, optical coherence tomography biomarkers, and impact on patient's quality of life. Based on the available evidence and clinical experience, the panel recommended the use of anti-VEGF intensive loading doses with the objective of achieving anatomic and visual responses as soon as possible, followed by a Treat & Extend (T&E) strategy to maintain VA improvement. Aflibercept was recommended for patients with a baseline decimal VA <0.5, followed by a T&E strategy, including the possibility to extend frequency of injections up to 16 weeks. Conclusion: An expert panel proposes a consensus for the management of DME in Spain. Early treatment initiation with anti-VEGF in DME patients is recommended to maintain or improve VA; aflibercept is recommended for patients with a poor baseline VA.

Predicting 30-Day Readmission Risk for Patients With Chronic Obstructive Pulmonary Disease Through a Federated Machine Learning Architecture on Findable, Accessible, Interoperable, and Reusable (FAIR) Data: Development and Validation Study.

BACKGROUND: Owing to the nature of health data, their sharing and reuse for research are limited by legal, technical, and ethical implications. In this sense, to address that challenge and facilitate and promote the discovery of scientific knowledge, the Findable, Accessible, Interoperable, and Reusable (FAIR) principles help organizations to share research data in a secure, appropriate, and useful way for other researchers. OBJECTIVE: The objective of this study was the FAIRification of existing health research data sets and applying a federated machine learning architecture on top of the FAIRified data sets of different health research performing organizations. The entire FAIR4Health solution was validated through the assessment of a federated model for real-time prediction of 30-day readmission risk in patients with chronic obstructive pulmonary disease (COPD). METHODS: The application of the FAIR principles on health research data sets in 3 different health care settings enabled a retrospective multicenter study for the development of specific federated machine learning models for the early prediction of 30-day readmission risk in patients with COPD. This predictive model was generated upon the FAIR4Health platform. Finally, an observational prospective study with 30 days follow-up was conducted in 2 health care centers from different countries. The same inclusion and exclusion criteria were used in both retrospective and prospective studies. RESULTS: Clinical validation was demonstrated through the implementation of federated machine learning models on top of the FAIRified data sets from different health research performing organizations. The federated model for predicting the 30-day hospital readmission risk was trained using retrospective data from 4.944 patients with COPD. The assessment of the predictive model was performed using the data of 100 recruited (22 from Spain and 78 from Serbia) out of 2070 observed (records viewed) patients during the observational prospective study, which was executed from April 2021 to September 2021. Significant accuracy (0.98) and precision (0.25) of the predictive model generated upon the FAIR4Health platform were observed. Therefore, the generated prediction of 30-day readmission risk was confirmed in 87% (87/100) of cases. CONCLUSIONS: Implementing a FAIR data policy in health research performing organizations to facilitate data sharing and reuse is relevant and needed, following the discovery, access, integration, and analysis of health research data. The FAIR4Health project proposes a technological solution in the health domain to facilitate alignment with the FAIR principles.

Identification of seasonal variation in the diagnosis of acute myeloid leukaemia: a population-based study.

Until now, the role that seasonal factors play in the aetiology of acute myeloid leukaemia (AML) has been unclear. Demonstration of seasonality in AML diagnosis would provide supportive evidence of an underlying seasonal aetiology. To investigate the potential seasonal and long-term trends in AML diagnosis in an overall population and in subgroups according to sex and age, we used population-based data from a Spanish hospital discharge registry. We conducted a larger study than any to date of 26 472 cases of AML diagnosed in Spain between 2004 and 2015. Using multivariable Poisson generalized linear autoregressive moving average modelling, we found an upward long-term trend, with monthly incidence rates of AML annually increasing by 0.4% [95% confidence interval (CI), 0.2%-0.6%; p = 0.0011]. January displayed the highest incidence rate of AML, with a minimum average difference of 7% when compared to February (95% CI, 2%-12%; p = 0.0143) and a maximum average difference of 16% compared to November (95% CI, 11%-21%; p < 0.0001) and August (95% CI, 10%-21%; p < 0.0001). Such seasonal effect was consistent among subgroups according to sex and age. Our finding that AML diagnosis is seasonal strongly implies that seasonal factors, such as infectious agents or environmental triggers, influence the development and/or proliferation of disease, pointing to prevention opportunities.
