A set of principles and practical suggestions for equitable fieldwork in biology.

Field biology is an area of research that involves working directly with living organisms in situ through a practice known as "fieldwork." Conducting fieldwork often requires complex logistical planning within multiregional or multinational teams, interacting with local communities at field sites, and collaborative research led by one or a few of the core team members. However, existing power imbalances stemming from geopolitical history, discrimination, and professional position, among other factors, perpetuate inequities when conducting these research endeavors. After reflecting on our own research programs, we propose four general principles to guide equitable, inclusive, ethical, and safe practices in field biology: be collaborative, be respectful, be legal, and be safe. Although many biologists already structure their field programs around these principles or similar values, executing equitable research practices can prove challenging and requires careful consideration, especially by those in positions with relatively greater privilege. Based on experiences and input from a diverse group of global collaborators, we provide suggestions for action-oriented approaches to make field biology more equitable, with particular attention to how those with greater privilege can contribute. While we acknowledge that not all suggestions will be applicable to every institution or program, we hope that they will generate discussions and provide a baseline for training in proactive, equitable fieldwork practices.

Evaluation of the hospital care quality perceived by patients with immune-mediated inflammatory diseases from the pharmacy service. SACVINFA study.

WHAT IS KNOWN AND OBJECTIVE: Immune-mediated inflammatory diseases (IMIDs) are a group of chronic and highly disabling diseases. The objective is to evaluate the satisfaction with the health care received by patients with the most prevalent IMIDs in Spain: inflammatory bowel disease (IBD), psoriasis (Ps) psoriatic arthritis (PsA), rheumatoid arthritis (RA) and spondyloarthropathies (SpAs), and to determine the factors that influence patient satisfaction. METHODS: This was an observational, cross-sectional, multicentre study in a real-world evidence context conducted in the Pharmacy Service in four hospital centres of the Community of Madrid that belong to the National Health System. The study included adult patients diagnosed with an IMID who had attended the Pharmacy Service at least three times. The patients were grouped according to the main IMID. Health care satisfaction was evaluated using the chronic patient experience assessment (IEXPAC) questionnaire. The responses to IEXPAC are grouped into three factors: productive interactions, new relational model and patient self-management, with a total score from 0 (worst) to 10 (best experience). Health-related quality of life (HRQoL) was also evaluated using the EQ-5D-5L questionnaire, and pharmacological adherence was evaluated through the Morisky-Green test. RESULTS AND DISCUSSION: A total of 578 patients were analysed (IBD = 25.3%; Ps = 19.7%; SpAs = 18.7%; RA = 18.5%; PsA = 17.8%). The mean age (SD) was 49.8 (12.3) years and 50.7% were male. The average score (SD) for the total IEXPAC sample was 6.6 (1.9). RA was the IMID with the lowest score, at 5.83 (2.0), significantly lower than the scores of Ps (SD) [7.01 (1.7); p = 0.003], IBD [6.83 (1, 9); p = 0.012] and SpAs [6.80 (1.6); p = 0.001]. Productive interactions (SD) [8.5 (1.8)] and patient self-management (SD) [7.3 (2.3)] were the factors with the highest scores, and the new relational model had the lowest score (SD) [3.2 (2.7)]. Male gender, a longer time interval between medication administrations and a higher HRQoL were correlated with better patient satisfaction. Current biological therapy (according to the Anatomical Chemical classification system) also had a significant influence; patients treated with tumour necrosis factor inhibitors and interleukin inhibitors showed greater satisfaction than those treated with selective immunosuppressants. WHAT IS NEW AND CONCLUSION: The IEXPAC results show high general satisfaction with care quality reported by patients with IMIDs treated in the Pharmacy Service. However, there are areas of improvement in care quality specially health professional-patient communication, such as increasing access to information, and promoting and facilitating relationships with patients in similar conditions.

The Characteristics and Functionalities of Mobile Apps Aimed at Patients Diagnosed With Immune-Mediated Inflammatory Diseases: Systematic App Search.

BACKGROUND: Immune-mediated inflammatory diseases (IMIDs) are systemic conditions associated with a high social and health impact. New treatments have changed the prognosis of IMIDs and have increased patient autonomy in disease management. Mobile apps have enormous potential to improve health outcomes in patients with IMIDs. Although a large number of IMID apps are available, the app market is not regulated, and functionality and reliability remain uncertain. OBJECTIVE: Our aims are to review available apps for patients with IMIDs or caregivers and to describe the main characteristics and functionalities of these apps. METHODS: We performed an observational, cross-sectional, descriptive study of all apps for patients with IMIDs. Between April 5 and 14, 2021, we conducted a search of the App Store (iOS) and Play Store (Android) platforms. We used the names of the different IMIDs as search terms. The inclusion criteria were as follows: content related to IMIDs, English or Spanish language, and user population consisting of patients and health care consumers, including family and caregivers. The variables analyzed were as follows: app name, type of IMID, platform (Android or iOS), country of origin, language, category of the app, cost, date of the last update, size, downloads, author affiliation, and functionalities. RESULTS: We identified 713 apps in the initial search, and 243 apps met the criteria and were analyzed. Of these, 37% (n=90) were on Android, 27.2% (n=66) on iOS, and 35.8% (n=87) on both platforms. The most frequent categories were health and well-being/fitness apps (n=188, 48.5%) and medicine (n=82, 37.9%). A total of 211 (82.3%) apps were free. The mean time between the date of the analysis and the date of the most recent update was 18.5 (SD 19.3) months. Health care professionals were involved in the development of 100 (41.1%) apps. We found differences between Android and iOS in the mean time since the last update (16.2, SD 14.7 months vs 30.3, SD 25.7 months) and free apps (85.6% vs 75.8%; respectively). The functionalities were as follows: general information about lifestyles, nutrition, or exercises (n=135, 55.6%); specific information about the disease or treatment (n=102, 42%); recording of symptoms or adverse events (n=51, 21%); agenda/calendar (n=44, 18.1%); reminder medication (n=41, 16.9%); and recording of patient-reported outcomes (n=41, 16.9%). A total of 147 (60.5%) apps had more than one functionality. CONCLUSIONS: IMID-related apps are heterogeneous in terms of functionality and reliability. Apps may be a useful complement to IMID care, especially inpatient education (their most frequent functionality). However, more than half of the IMID apps had not been developed by health care professionals or updated in the last year.

Information and Communication Technologies in Patients With Immune-Mediated Inflammatory Diseases: Cross-sectional Survey.

BACKGROUND: Information and communication technologies (ICTs) are changing the traditional health care model and redefining personalized health. ICTs offer effective communication and real-time monitoring of patients and provide additional data to support clinical decision-making, improve the quality of care, and contribute to the empowerment of patients. However, evidence on the use of ICTs and digital preferences of immune-mediated inflammatory disease (IMID) patients is scarce. OBJECTIVE: The aim of this study is to describe the degree of use of ICTs in patients with IMIDs (including rheumatic diseases, inflammatory bowel diseases, and psoriasis), identify their needs, and analyze their interest in the use of apps as tools for better management of their disease. METHODS: A questionnaire was created by a multidisciplinary team including pharmacists, rheumatologists, gastroenterologists, dermatologists, and nurses with experience in ICTs applied to the field of IMID. The survey included 27 questions organized into 3 blocks: (1) sociodemographic characteristics, (2) ICT use for health-related information, and (3) patient expectations about mobile health. RESULTS: A total of 472 questionnaires were analyzed. Overall, 52.9% (250/472) of patients were diagnosed with a rheumatologic disease, 39.4% (186/472) with inflammatory bowel disease, and 12.3% (58/472) with psoriasis. The state of health was considered good by 45.6% (215/472) of patients. Patients were interested in staying informed about health issues in 86.9% (410/427) of cases and sought health-related information mainly from the internet (334/472, 70.8%) and health care professionals (318/472, 67.4%). Overall, 13.6% (64/472) did not trust the health information they found in internet. Of the patients, 42.8% (202/472) had a health app, and 42.2% (199/472) had found it on their own. Patients would like a health app to help mainly to manage appointments (281/472, 59.5%), obtain information about their diseases and treatments (274/472, 58.1%), and get in contact with health professionals (250/472, 53.0%). Overall, 90.0% (425/472) of patients reported they would use an app to manage their IMID if their health professional recommended it, and 58.0% (274/472) would pay or probably be willing to pay for it. CONCLUSIONS: IMID patients were very interested in finding health-related information via ICTs, especially using smartphones and apps recommended by health professionals. Appointment management, advice on disease and treatment management, and personalized communication with health professionals were the most desired app features identified. Health professionals should play an essential role in recommending and validating these tools to ensure they are of high quality.

Development of Methotrexate Complexes Endowed with New Biological Properties Envisioned for Musculoskeletal Regeneration in Rheumatoid Arthritis Environments.

Methotrexate (MTX) administration is the gold standard treatment for rheumatoid arthritis (RA), but its effects are limited to preventing the progression of the disease. Therefore, effective regenerative therapies for damaged tissues are still to be developed. In this regard, MTX complexes of general molecular formula M(MTX)·xH2O, where M = Sr, Zn, or Mg, were synthesized and physicochemically characterized by TGA, XRD, NMR, ATR-FTIR, and EDAX spectroscopies. Characterization results demonstrated the coordination between the different cations and MTX via two monodentate bonds with the carboxylate groups of MTX. Cation complexation provided MTX with new bioactive properties such as increasing the deposition of glycosaminoglycans (GAGs) and alternative anti-inflammatory capacities, without compromising the immunosuppressant properties of MTX on macrophages. Lastly, these new complexes were loaded into spray-dried chitosan microparticles as a proof of concept that they can be encapsulated and further delivered in situ in RA-affected joints, envisioning them as a suitable alternative to oral MTX therapy.

Surfactant Protection Efficacy at Surfaces Varies with the Nature of Hydrophobic Materials.

OBJECTIVE: Monoclonal antibodies are in contact with many different materials throughout their life cycle from production to patient administration. Plastic surfaces are commonly found in single use bags, syringes, perfusion bags and tubing and their hydrophobic nature makes them particularly prone for adsorption of therapeutic proteins. The addition of surfactants in therapeutic formulations aims at minimizing surface and interface adsorption of the active molecules. However, their protection efficacy related to the nature of the plastic material is still poorly investigated. METHODS: We use real-time surface-sensitive techniques and immunosorbent assays, to quantify surfactant and monoclonal antibody adsorption on hydrophobic model surfaces and different plastic polymers to analyse the effect of material surface properties on the level of surfactant protection. RESULTS: We show that Polysorbate 80 protects monoclonal antibodies significantly better from adsorption on a polystyrene surface than on a hexadecane self-assembled monolayer, used as a model surface with similar hydrophobicity. This enhanced protective effect on polystyrene is observed for different antibodies and also other surfactants, and its extent depends on the surfactant concentration for a given antibody concentration. A comparative adsorption study allows ranking different in-use plastics and highlights the dependence of Polysorbate 80 protection efficacy on the nature of the plastic material. CONCLUSION: This study demonstrates that, beyond hydrophobicity, the nature of plastic polymer surfaces affects surfactant adsorption and thereby impacts their protection efficacy in therapeutic antibody formulations.

Cerebrovascular disease in patients with COVID-19: neuroimaging, histological and clinical description.

Since the appearance of the first case of coronavirus disease 2019 (COVID-19) a pandemic has emerged affecting millions of individuals worldwide. Although the main clinical manifestations are respiratory, an increase in neurological conditions, specifically acute cerebrovascular disease, has been detected. We present cerebrovascular disease case incidence in hospitalized patients with SARS-CoV-2 infection. Patients were confirmed by microbiological/serological testing, or on chest CT semiology. Available data on co-morbidity, laboratory parameters, treatment administered, neuroimaging, neuropathological studies and clinical evolution during hospitalization, measured by the modified Rankin scale, were analysed. A bivariate study was also designed to identify differences between ischaemic and haemorrhagic subtypes. A statistical model of binary logistic regression and sensitivity analysis was designed to study the influence of independent variables over prognosis. In our centre, there were 1683 admissions of patients with COVID-19 over 50 days, of which 23 (1.4%) developed cerebrovascular disease. Within this group of patients, cerebral and chest CT scans were performed in all cases, and MRI in six (26.1%). Histological samples were obtained in 6/23 cases (two brain biopsies, and four arterial thrombi). Seventeen patients were classified as cerebral ischaemia (73.9%, with two arterial dissections), five as intracerebral haemorrhage (21.7%), and one leukoencephalopathy of posterior reversible encephalopathy type. Haemorrhagic patients had higher ferritin levels at the time of stroke (1554.3 versus 519.2, P = 0.004). Ischaemic strokes were unexpectedly frequent in the vertebrobasilar territory (6/17, 35.3%). In the haemorrhagic group, a characteristic radiological pattern was identified showing subarachnoid haemorrhage, parieto-occipital leukoencephalopathy, microbleeds and single or multiple focal haematomas. Brain biopsies performed showed signs of thrombotic microangiopathy and endothelial injury, with no evidence of vasculitis or necrotizing encephalitis. The functional prognosis during the hospital period was unfavourable in 73.9% (17/23 modified Rankin scale 4-6), and age was the main predictive variable (odds ratio = 1.5; 95% confidence interval 1.012-2.225; P = 0.043). Our series shows cerebrovascular disease incidence of 1.4% in patients with COVID-19 with high morbidity and mortality. We describe pathological and radiological data consistent with thrombotic microangiopathy caused by endotheliopathy with a haemorrhagic predisposition.

Does the fortified milk with high iron dose improve the neurodevelopment of healthy infants? Randomized controlled trial.

BACKGROUND: Since iron plays an important role in several physiological processes, its deficiency but also overload may harm the development of children. The aim was to assess the effect of iron-fortified milk on the iron biochemical status and the neurodevelopment of children at 12 months of age. METHODS: Randomized controlled trial conducted in 133 Spanish children, allocated in two groups to receive formula milk fortified with 1.2 or 0.4 mg/100 mL of iron between 6 and 12 months of age. Psychomotor (PDI) and Mental (MDI) Development Index were assessed by the Bayley Scales before and after the intervention. Maternal obstetrical and psychosocial variables were recorded. The biochemical iron status of children was measured and data about breastfeeding, anthropometry and infections during the first year of life were registered. RESULTS: Children fortified with 1.2 mg/100 mL of iron, compared with 0.4 mg/100 mL, showed higher serum ferritin (21.5 vs 19.1 µg/L) and lower percentage of both iron deficiency (1.1 to 5.9% vs 3.8 to 16.7%, respectively, from 6 to 12 months) and iron deficiency anemia (4.3 to 1.1% vs 0 to 4.2%, respectively, from 6 to 12 months) at the end of the intervention. No significant differences were found on neurodevelopment from 6 to 12 months between children who received high dose of Fe compared with those who received low dose. CONCLUSION: Despite differences on the iron status were observed, there were no effects on neurodevelopment of well-nourished children in a developed country after iron supplementation with doses within dietary recommendations. Follow-up studies are needed to test for long-term neurodevelopmental improvement. TRIAL REGISTRATION: Retrospectively registered in ClinicalTrials.gov with the ID: NCT02690675.

Effectiveness and Safety of Ombitasvir-Paritaprevir/Ritonavir and Dasabuvir With or Without Ribavirin for HCV Genotype 1 Infection for 12 Weeks Under Routine Clinical Practice.

BACKGROUND: No previous studies exist examining the effectiveness and safety in real clinical practice of the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir (OBV/PTV/r+DSV). OBJECTIVE: To evaluate the effectiveness and safety in real clinical practice of the combination of OBV/PTV/r+DSV with or without ribavirin for 12 weeks in treatment-naïve and previously treated adult patients with chronic hepatitis C virus (HCV) genotype 1 infection. METHODS: This was an observational study of a prospective cohort of treatment-naïve and pretreated adult patients who received 12 weeks of OBV/PTV/r (25/150/100 mg once daily) and DSV (250 mg twice daily) with or without ribavirin. The primary effectiveness outcome was sustained virological response 12 weeks after the end of treatment (SVR12). Safety outcomes were presented by the incidence of adverse events. RESULTS: A total of 116 of 121 patients achieved a SVR12 (95.9%, 95% CI = 90.6-98.6). The SVR12 rate was 93.8% (95% CI = 86.0-97.9) in cirrhotic patients and 100% (95% CI = 91.4-100.0) in noncirrhotic patients. Adverse events occurred in 91.7% of patients, of which 81.8% were grade 1/2, and none led to premature discontinuation. Grade 3 adverse events were reported in 9.9% of patients. The most frequent adverse event was anemia (52.1%), although only 1.6% had a hemoglobin level below 8 g/dL. The incidence of any adverse event was higher in the group of patients who received ribavirin (96.5% vs 80.0%, P = 0.002). CONCLUSIONS: The combination of OBV/PTV/r+DSV with or without ribavirin for 12-week settings achieved a high rate of SVR12, with an acceptable safety profile in routine clinical care.

[Recognition of Medication and Adherence to Medical Prescriptions in Patients Using Generic Drugs]. / Reconocimiento de la medicación y Cumplimiento Terapéutico en Pacientes Usuarios de Medicamentos Genéricos.

Bases: The prescription based on the active ingredients has fostered the rise of generic drugs, increasing the variety of presentations, which can cause confusion, mistakes and encourage the medication nonadherence. The elderly may be at higher risk due to associated comorbidities and polymedication. Objectives: To assess recognition of the medication and adherence to medical prescription in elderly patients with changes in their medication appearance. Methodology: Descriptive cross-sectional study of a sample made by recruitment in Primary Health Care. We performed structured interviews to 96 patients over 65 years: we evaluated the adherence to medical prescription through the Morisky-Green test and we assessed the ability to recognize the medication by a discrimination test using drug boxes. Results: 99% of the patients (CI95% 94.3-99.8%) reported never to fail in taking their medication. 84.4% (CI95% 75.8-90%) recognized their medication without errors, 67.7% (CI95% 57.8-76.2% recognized the correct active ingredient and 56.2% (CI95% 46.3-65.7%) the right amount of active ingredient. A higher level of recognition was found in women, patients with a superior education level and those without polymedication (p < 0.05). Half of the patients (51%; CI95% 41.2-60.8%) showed adherence to medical prescription, but we found no significant relationship with the socio-demographic variables or the degree of recognition of the medication. Conclusions: High rate of lack of adherence to drug therapy, but similar to other publications. The education level influences the recognition of the medication, while polymedication has a negative effect. The wrong appreciation by patients considering that they take appropriately their medication contrasts with the real data, and should be taken into consideration.

Diastolic Dysfunction Following Anthracycline-Based Chemotherapy in Breast Cancer Patients: Incidence and Predictors.

INTRODUCTION: Cardiotoxicity represents a major limitation for the use of anthracyclines or trastuzumab in breast cancer patients. Data from longitudinal studies of diastolic dysfunction (DD) in this group of patients are scarce. The objective of the present study was to assess the incidence, evolution, and predictors of DD in patients with breast cancer treated with anthracyclines. METHODS: This analytical, observational cohort study comprised 100 consecutive patients receiving anthracycline-based chemotherapy (CHT) for breast cancer. All patients underwent clinical evaluation, echocardiogram, and measurement of cardiac biomarkers at baseline, end of anthracycline-based CHT, and at 3 months and 9 months after anthracycline-based CHT was completed. Fifteen patients receiving trastuzumab were followed with two additional visits at 6 and 12 months after the last dose of anthracycline-based CHT. A multivariate analysis was performed to find variables related to the development of DD. Fifteen of the 100 patients had baseline DD and were excluded from this analysis. RESULTS: At the end of follow-up (median: 12 months, interquartile range: 11.1-12.8), 49 patients (57.6%) developed DD. DD was persistent in 36 (73%) but reversible in the remaining 13 patients (27%). Four patients developed cardiotoxicity (three patients had left ventricular systolic dysfunction and one suffered a sudden cardiac death). None of the patients with normal diastolic function developed systolic dysfunction during follow-up. In the logistic regression model, body mass index (BMI) and age were independently related to the development of DD, with the following odds ratio values: BMI: 1.19 (95% confidence interval [CI]: 1.04-1.36), and age: 1.12 (95% CI: 1.03-1.19). Neither cardiac biomarkers nor remaining clinical variables were predictors of DD. CONCLUSION: Development of diastolic dysfunction after treatment with anthracycline or anthracycline- plus trastuzumab chemotherapy is common. BMI and age were independently associated with DD following anthracycline chemotherapy.

Mood states and academic performance in the objective structured clinical examination. The mediating effect of self-efficacy.

BACKGROUND: The role of self-efficacy on academic outcomes in clinical simulation evaluations is well-known. However, no previous studies have reported the mediating effect of self-efficacy in the link between mood state and academic performance in the Objective Structured Clinical Examination (OSCE). OBJECTIVES: This study explores the following aims: i) to determine the effects of mood states on academic performance; ii) to assess the effect of mood states on self-efficacy; and iii) to analyze whether self-efficacy mediates the relationship between mood state and academic performance in the OSCE. DESIGN: This quantitative and cross-sectional study received Institutional Review Board approval. SETTINGS: A private university in Santiago, Chile. PARTICIPANTS: A convenience sample of 117 nursing students from fourth and sixth semester. METHODS: Data were collected using two questionnaires (the short version of the Profile of Mood State, and the General Self-Efficacy Scale), and the objective structured clinical examination in adult medical-surgical nursing and pediatric nursing courses. RESULTS: Mood state has a significant effect on self-efficacy ß = -0.068 p = .001. There was, however, no significant relationship between mood and academic performance (= - 0.004 p = .114). Similarly, Sobel's test indicated a non-significant mediation effect for self-efficacy-0.000544; 95 %; CI (-0.00256, 0.00148) p = .597. CONCLUSIONS: The results of this study improve the understanding of students' self-efficacy and academic performance. Further investigation regarding the use of the self-efficacy construct as a mediating variable in different high-stakes evaluations and in students with varying training levels is needed.

Development of an ELISA-based device to quantify antibody adsorption directly on medical plastic surfaces.

Monoclonal antibodies (mAbs) encounter numerous interfaces during manufacturing, storage, and administration. While protein adsorption at the solid/liquid interface has been widely explored on model surfaces, a key challenge remains - the detection of very small amounts of adsorbed mAb directly on real medical surfaces. This study introduces a novel ELISA-based device, ELIBAG, a new tool for measuring mAb adsorption on medical bags. The efficacy of this device was highlighted by successfully confirming the adsorption of an IgG1 on two medical bag types: a polypropylene IV administration bag and a low-density polyethylene pharmaceutical manufacturing bag. We also investigated IgG1 adsorption on plastic model surfaces, revealing a similar range of mAb bulk concentration for surface saturation on both model and bag surfaces. This innovative device, characterized by its high-throughput and rapid approach, paves the way for extensive investigations into therapeutic proteins, such as mAbs, adsorption on a variety of medical or pharmaceutical surfaces, diverse adsorption conditions, and the influence of excipients employed in mAb formulation, which could enhance the knowledge of mAb interactions with plastic surfaces throughout their lifecycle.

Evaluating surfactant effectiveness in preventing antibody adsorption directly on medical surfaces using a novel device.

Biopharmaceuticals, specifically antibody-based therapeutics, have revolutionized disease treatment. Throughout their lifecycle, these therapeutic proteins are exposed to several stress conditions, for example at interfaces, posing a risk to the drug product stability, safety and quality. Therapeutic protein adsorption at interfaces may lead to loss of active product and protein aggregation, with potential immunogenicity risks. Non-ionic surfactants are commonly added in formulations to mitigate protein-surface interactions. However, their effectiveness varies with the monoclonal antibody (mAb), and model surface material. Extrapolating findings from model surfaces to real medical surfaces is challenging due to diverse properties. This study pioneers the evaluation of surfactant effectiveness in preventing mAb adsorption directly on medical surfaces at the medical bag/formulation interface, utilizing the ELIBAG device. The adsorption of different protein modalities, mAbs and antibody-drug conjugate (ADC), using three surfactants (PS80, PS20, and P188), was examined across various medical surfaces, IV bags and manufacturing bags, and model surfaces. Our findings reveal that surfactants prevent mAb adsorption depending on the mAb modality, surfactant type and concentration, and surface material. This research underscores the importance of considering real medical surfaces in direct contact with formulations, offering insights for enhancing drug product development and ensuring material-protein compatibility in real world use.

Cost-Effectiveness Analysis of Abrocitinib Compared with Other Systemic Treatments for Severe Atopic Dermatitis in Spain.

INTRODUCTION: Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by itchy, painful, and dry skin. Despite the great number of available therapies, economic evaluations are still needed to provide evidence on their cost efficiency. This research aimed to evaluate the cost effectiveness of the Janus kinase (JAK) inhibitor abrocitinib (200 mg) compared with dupilumab (300 mg), tralokinumab (300 mg), baricitinib (2 and 4 mg), and upadacitinib (15 and 30 mg) for the treatment of patients with severe AD from the Spanish National Health System (NHS) perspective. METHODS: A hybrid model consisting of a decision tree linked to a Markov model was developed to estimate costs, quality-adjusted life-years (QALYs), total years in response and incremental cost-per-QALY gained (willingness-to-pay [WTP] threshold: €25,000/QALY). Adults with severe AD entered the decision tree and response (75% reduction in baseline Eczema Area and Severity Index score, EASI-75) was considered at 16 and 52 weeks. After this time, patients entered the Markov model (remainder of the 10-year time horizon), which consisted of three health states: maintenance with active therapy, subsequent treatment, or death. All costs were presented in 2022 euros (€). Additionally, cost per number-needed-to-treat (NNT) was calculated for abrocitinib and dupilumab based on a head-to-head post-hoc analysis. RESULTS: Abrocitinib 200 mg was dominant (i.e., lower incremental costs and higher incremental benefit) compared with all studied alternatives (dupilumab 300 mg, tralokinumab 300 mg, baricitinib 2 and 4 mg, upadacitinib 15 and 30 mg) with a QALYs gain of 0.49, 0.60, 0.64, 0.43, 0.45, and 0.08, respectively, and per-person costs savings of €22,097, €24,140, €14,825, €7,116, €12,805, and €45,189, respectively. Considering the WTP threshold, abrocitinib was dominant or cost effective compared with all alternatives for most simulations. Additionally, abrocitinib was dominant compared with all alternatives when evaluating the cost effectiveness over a 5-year time horizon. NNT showed that abrocitinib was dominant versus dupilumab. CONCLUSIONS: The results of the study show that abrocitinib is a cost-effective therapy compared with other JAK inhibitors and biological therapies from the Spanish NHS perspective.

Perceived quality of life by patients with immune-mediated inflammatory diseases treated with biological therapies. SACVINFA study. / [Artículo traducido] Calidad de vida percibida por pacientes con enfermedades inflamatorias inmunomediadas tratados con terapias biológicas. Estudio SACVINFA.

OBJECTIVES: To evaluate health-related quality of life perceived by patients with the most prevalent immune-mediated inflammatory diseases in Spain: inflammatory bowel disease (IBD), psoriasis (Ps), psoriatic arthritis (AP), rheumatoid arthritis (RA), and spondyloarthropathies (SpAs), and to determine the factors that influence patient quality of life. METHODS: The SACVINFA study (SA = satisfaction, CV = quality of life, IN = immune-mediated, FA = pharmacy) consisted of an observational study conducted in 4 hospitals in the Community of Madrid. A cross-sectional analysis was made of adult patients diagnosed with an immune-mediated inflammatory disease who attended the Pharmacy Service. Quality of life was assessed using the EQ-5D-5L questionnaire (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) and specific questionnaires: SIBDQ-9, DLQI, PsAQoL, QoL-RA and ASQoL. RESULTS: A total of 578 patients were analyzed (inflammatory bowel disease = 25.3%; psoriasis = 19.7%; spondyloarthropathies = 18.7%; rheumatoid arthritis = 18.5%; psoriatic arthritis = 17.8%). The mean age (SD) was 49.8 (12.3) years and 50.7% were male. The average score (SD) for the global EQ-5D- 5 L was 0.771 (0.2) and the mean (SD) visual analogue scale score was 71.5 (20.0). Type of immune-mediated inflammatory diseases was associated with differences in quality of life showing psoriasis and inflammatory bowel disease higher values of EQ-5D-5L than psoriatic arthritis, rheumatoid arthritis and spondyloarthropathies, p < 0,05 in all comparisons. Patients with RA, IBD, and Ps achieved 70% of the maximum score, while patients with PsA and SpAs did not reach 50% of the maximum possible score. Female gender, a state of moderate/severe disease severity, an older age and a higher number of previous treatments were correlated with worse quality of life. Conversely, persistence to current treatment correlated with better quality of life. CONCLUSIONS: Patients with immune-mediated inflammatory diseases have markedly affected quality of life, mainly in the pain/discomfort dimension, especially in those immune-mediated inflammatory diseases with a rheumatological component.

Detection and reduction of errors in parenteral nutrition compounding through gravimetric and product control. / [Artículo traducido] Detección y reducción de errores en la elaboración de la nutrición parenteral mediante control gravimétrico y de producto.

OBJECTIVE: To analyze the errors in the preparation of parenteral nutrition in a Pharmacy Service, detected through an already consolidated gravimetric and product quality control, and compare them with those detected during the initial years of implementing this quality control. METHODS: All errors detected through quality control in the compounding of pediatric and adult parenteral nutrition between 2019 and 2021 were prospectively analyzed. This quality control consisted of 3 sequential processes: a visual check, a gravimetric control, and a product control. Errors were classified as gravimetric, when the nutrition had a deviation of more than 5% from the theoretical weight, or as product errors when a qualitative or quantitative error was detected upon reviewing the remainder of the components used. These errors were analyzed in terms of type and the component involved. A comparison was made with the errors detected during the implementation phase of this quality control from 2016 to 2018. RESULTS: A total of 41,809 parenteral nutritions were reviewed, and 345 errors were detected (0.83% of the preparations); of these, 59 errors were found in pediatric nutritions (0.68% of them), and 286 in adult nutritions (0.86% of them). Among these errors, 193 were of gravimetric nature, while 152 were detected through product control. The main components involved in product errors were electrolytes, primarily due to the addition of excessive volumes and the use of incorrect components. A significant absolute reduction of 0.71% (p < 0.05) in the total number of errors was observed when compared to the implementation phase. This reduction was consistent in both gravimetric errors (-0.59%) and product-related errors (-0.12%) (p < 0.05). CONCLUSIONS: Comprehensive quality control of parenteral nutrition preparation is an easily implementable tool that effectively detected and prevented significant errors. Furthermore, its widespread adoption contributed to a reduction in the overall error count.

Detection and reduction of errors in parenteral nutrition compounding through gravimetric and product control.

OBJECTIVE: To analyze the errors in the preparation of parenteral nutrition in a Pharmacy Service, detected through an already consolidated gravimetric and product quality control, and compare them with those detected during the initial years of implementing this quality control. METHODS: All errors detected through quality control in the compounding of pediatric and adult parenteral nutritions between 2019 and 2021 were prospectively analyzed. This quality control consisted of 3 sequential processes: a visual check, a gravimetric control, and a product control. Errors were classified as gravimetric, when the nutrition had a deviation of more than 5% from the theoretical weight, or as product errors when a qualitative or quantitative error was detected upon reviewing the remainder of the components used. These errors were analyzed in terms of type and the component involved. A comparison was made with the errors detected during the implementation phase of this quality control from 2016 to 2018. RESULTS: A total of 41,809 parenteral nutritions were reviewed, and 345 errors were detected (0.83% of the preparations); of these, 59 errors were found in pediatric nutritions (0.68% of them), and 286 in adult nutritions (0.86% of them). Among these errors, 193 were of gravimetric nature, while 152 were detected through product control. The main components involved in product errors were electrolytes, primarily due to the addition of excessive volumes and the use of incorrect components. A significant absolute reduction of 0.71% (P < .05) in the total number of errors was observed when compared to the implementation phase. This reduction was consistent in both gravimetric errors (-0.59%) and product-related errors (-0.12%) (P < .05). CONCLUSIONS: Comprehensive quality control of parenteral nutrition preparation is an easily implementable tool that effectively detected and prevented significant errors. Furthermore, its widespread adoption contributed to a reduction in the overall error count.

BioMOF@cellulose Glycerogel Scaffold with Multifold Bioactivity: Perspective in Bone Tissue Repair.

The development of new biomaterials for musculoskeletal tissue repair is currently an important branch in biomedicine research. The approach presented here is centered around the development of a prototypic synthetic glycerogel scaffold for bone regeneration, which simultaneously features therapeutic activity. The main novelty of this work lies in the combination of an open meso and macroporous nanocrystalline cellulose (NCC)-based glycerogel with a fully biocompatible microporous bioMOF system (CaSyr-1) composed of calcium ions and syringic acid. The bioMOF framework is further impregnated with a third bioactive component, i.e., ibuprofen (ibu), to generate a multifold bioactive system. The integrated CaSyr-1(ibu) serves as a reservoir for bioactive compounds delivery, while the NCC scaffold is the proposed matrix for cell ingrowth, proliferation and differentiation. The measured drug delivery profiles, studied in a phosphate-buffered saline solution at 310 K, indicate that the bioactive components are released concurrently with bioMOF dissolution after ca. 30 min following a pseudo-first-order kinetic model. Furthermore, according to the semi-empirical Korsmeyer-Peppas kinetic model, this release is governed by a case-II mechanism, suggesting that the molecular transport is influenced by the relaxation of the NCC matrix. Preliminary in vitro results denote that the initial high concentration of glycerol in the NCC scaffold can be toxic in direct contact with human osteoblasts (HObs). However, when the excess of glycerol is diluted in the system (after the second day of the experiment), the direct and indirect assays confirm full biocompatibility and suitability for HOb proliferation.
