Certolizumab pegol effectiveness, survival and safety in patients with psoriasis: A multicenter retrospective analysis in daily clinical practice by the Spanish Psoriasis Group.

BACKGROUND: Certolizumab is an Fc-free PEGylated tumor necrosis factor-alpha (TNFα) inhibitor recently approved for the treatment of moderate-to-severe plaque psoriasis, although there is limited real-world evidence on the effectiveness and safety in patients with plaque psoriasis treated with certolizumab. The objective of this article is to determine the effectiveness, drug survival, and safety, including pregnancy, childbirth, and lactation, of certolizumab in moderate-to-severe plaque psoriasis under real-world conditions. METHODS: This is a retrospective, multicenter, observational study performed in 15 hospitals in Spain. It evaluates the effectiveness and safety of certolizumab in plaque psoriasis in the clinical practice setting. RESULTS: A total of 67 patients (73% female) were evaluated with a mean baseline Psoriasis Area Severity Index (PASI) of 8.9. At Week 12, the mean PASI was 2.3 (n = 67), 1.3 (n = 57) at Week 24 and 1.3 at Week 52 (n = 34). Absolute PASI < 3 was achieved in 69, 86, and 92% of patients at Weeks 12, 24, and 52, respectively, as observed. For its part, using the under-response imputation analysis, PASI < 3 at Weeks 12, 24, and 52 were achieved by 69, 73, and 49% of the patients, respectively. A total of 35 patients (52%) had concomitant psoriatic arthritis, and, in 24 of them, Disease Activity in Psoriatic Arthritis Score (DAPSA) was recorded at baseline, with a mean value of 17.9 which decreased to 8.2 at Week 12 (n = 22) and to 3.6 at Week 24 (n = 18). Certolizumab treatment was discontinued in 14 out of 67 patients (21%), due to lack/loss of cutaneous or articular effectiveness (n = 11) or patient decision (n = 2) or adverse event in only one patient who developed active tuberculosis. A lower baseline PASI [hazard ratio (HR): 1.12 (1.02-1.23); P = 0.023] and a more significant reduction in PASI at Week 12 [HR: 1.16 (1.07-1.27); P < 0.001] and Week 52 [HR: 1.47 (1.11-1.96); P = 0.007] was shown to be significantly related with better survival for the entire follow-up period. Fourteen patients were treated during pregnancy and/or lactation without reporting adverse events in either the patient or the newborn. CONCLUSIONS: Certolizumab consistently showed high effectiveness and drug survival rates in this real-life cohort. The safety demonstrated in clinical trials during pregnancy and lactation seems to be confirmed in clinical practice.

Effect of single-dose, live, attenuated dengue vaccine in children with or without previous dengue on risk of subsequent, virologically confirmed dengue in Cebu, the Philippines: a longitudinal, prospective, population-based cohort study.

BACKGROUND: A three-dose dengue vaccine (CYD-TDV) was licensed for use in children aged 9 years and older starting in 2015 in several dengue-endemic countries. In 2016, the Philippine Department of Health implemented a dengue vaccination programme, which was discontinued because of safety concerns. We assessed the relative risk of developing virologically confirmed dengue among children who did or did not receive a single dose of CYD-TDV by previous dengue virus (DENV) infections at baseline classified as none, one, and two or more infections. METHODS: In this longitudinal, prospective, population-based cohort study, we enrolled healthy children (aged 9-14 years) residing in Bogo or Balamban, Cebu, Philippines, between May 2, and June 2, 2017, before a mass dengue vaccination campaign, via the Rural Health Unit in Bogo and three Rural Health Units in Balamban. We collected demographic information and sera for baseline DENV serostatus and conducted active surveillance for acute febrile illness. Children who developed acute febrile illness were identified, clinical data were collected, and blood was drawn for confirmation of dengue by RT-PCR. The primary outcome was the relative risk of developing virologically confirmed dengue among children who received or did not receive a single dose of CYD-TDV by DENV serostatus at baseline. FINDINGS: A single dose of CYD-TDV did not confer protection against virologically confirmed dengue in children who had none or one previous DENV infection at baseline. One dose conferred significant protection against hospital admission for virologically confirmed dengue among participants who had two or more previous DENV infections at baseline during the first 3 years (70%, 95% CI 20-88; p=0·017) and the entire follow-up period (67%, 19-87; p=0·016). INTERPRETATION: The risk of developing virologically confirmed dengue after a single dose of CYD-TDV varied by baseline DENV serostatus. Since the study assessed the effect of only a single dose, the findings cannot inform decisions on vaccination by public health officers. However, the findings have implications for children who receive an incomplete vaccination regimen and these results should prompt more detailed analyses in future trials on dengue vaccines.

Incidence of urinary incontinence after hip fracture surgery and associated risk factors: a prospective study.

BACKGROUND: The contribution of the postoperative process to developing or worsening urinary incontinence (UI) after hip fracture surgery (HFS) remains unclear. We aimed to evaluate UI incidence and worsening among older patients undergoing HFS, and explore associated risk factors. METHODS: This prospective cohort study included patients ≥ 75 years admitted between October 2019 and October 2021 to the Traumatology Service of three hospitals in the Consorci Sanitari de Alt-Penedès i Garraf (Barcelona, Spain) with hip fracture requiring surgical treatment. UI was assessed using the first two questions of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) at baseline and at days 30 (± 3 days) and 90 (± 3 days) after HFS. Surgery-related data and post-surgical complications were recorded. RESULTS: A total of 248 patients with a mean (SD) age of 85.8 (6.78) years were included; 77.8% were female and 154 (62.1%) had UI at baseline. After HFS, 3.24% experienced urinary tract infections (UTIs), 3.64%, acute urinary retention (AUR), 8.57%, constipation, and 53.9%, prolonged catheterization (> 24 h). Fifty-eight patients without baseline UI developed UI at 30 days, resulting in a UI incidence of 61.7% (95% CI 51.1-71.54) between days 0 and 30. Of the 248 patients, 146 (59.1%) experienced worsening of UI. AUR and UTIs were identified as risk factors for UI development and worsening after HFS, respectively. CONCLUSION: The incidence of UI in older patients after HFS is significant. Patient management protocols should consider AUR and UTIs to reduce or eliminate the incidence of UI in older patients undergoing HFS.

Theoretical study of the catalytic performance of Fe and Cu single-atom catalysts supported on Mo2C toward the reverse water-gas shift reaction.

The reverse water-gas shift (RWGS) is an attractive process using CO2 as a chemical feedstock. Single-atom catalysts (SACs) exhibit high catalytic activity in several reactions, maximizing the metal use and enabling easier tuning by rational design than heterogeneous catalysts based on metal nanoparticles. In this study, we evaluate, using DFT calculations, the RWGS mechanism catalyzed by SACs based on Cu and Fe supported on Mo2C, which is also an active RWGS catalyst on its own. While Cu/Mo2C showed more feasible energy barriers toward CO formation, Fe/Mo2C presented lower energy barriers for H2O formation. Overall, the study showcases the difference in reactivity between both metals, evaluating the impact of oxygen coverage and suggesting Fe/Mo2C as a potentially active RWGS catalyst based on theoretical calculations.

2D carbon nitride as a support with single Cu, Ag, and Au atoms for carbon dioxide reduction reaction.

The electrochemical conversion of CO2 into value-added chemicals is an important approach to recycling CO2. In this work, we have combined the most efficient metal catalysts for this reaction, namely Cu, Ag, and Au, as single-atom particles dispersed on a two-dimensional carbon nitride support, with the aim of exploring their performance in the CO2 reduction reaction. Here, we report density functional theory computations showing the effect of single metal-atom particles on the support. We found that bare carbon nitride needed a high overpotential to overcome the energy barrier for the first proton-electron transfer, while the second transfer was exergonic. The deposition of single metal atoms enhances the catalytic activity of the system as the first proton-electron transfer is favored in terms of energy, although strong binding energies were found for CO adsorption on Cu and Au single atoms. Our theoretical interpretations are consistent with the experimental evidence that the competitive H2 generation is favored due to the strong CO binding energies. Our computational study paves the road to finding suitable metals that catalyze the first proton-electron transfer in the carbon dioxide reduction reaction and produce reaction intermediates with moderate binding energies, promoting a spillover to the carbon nitride support and thereby serving as bifunctional electrocatalysts.

Nuestra experiencia en el manejo diagnóstico-terapéutico a corto plazo del paciente con displasia anal / Our experience in the short-term diagnostic-therapeutic management of the patient with anal dysplasia

Introducción: La neoplasia intraepitelial anal (NIA) es una lesión premaligna del carcinoma escamoso anal. Los varones VIH que tienen sexo con varones, es la población de riesgo más afectada. La citología y anuscopia son los métodos mejor aceptados para su diagnóstico, aunque es controvertido qué pacientes deben completarlo con una biopsia. Tampoco está bien establecido qué pacientes deben someterse a tratamiento y cuál es el mejor. Con este estudio, queremos exponer nuestra experiencia en el manejo diagnóstico-terapéutico de la NIA a corto plazo. Métodos: Estudio observacional retrospectivo de pacientes con riesgo de NIA con una citología anal alterada a los que se les realizó una anuscopia de alta resolución con biopsia. Tras la confirmación histológica de displasia iniciaron tratamiento con ácido tricloroacético. Se comprobó su efectividad con una citología posterior. Se analizaron las variables demográficas de la muestra y los resultados de las pruebas diagnósticas y de tratamiento. Resultados: La mayoría eran varones VIH positivos (104/115) y el 50% mantenían relaciones sexuales con otros varones. Se incluyeron 115 pacientes con citología anal alterada, de los cuales el 92% presentaron displasia en la biopsia. El 97% con atipia de significado incierto en la citología presentaron displasia histológicamente. El 60% de los pacientes normalizó la citología tras el tratamiento. Conclusión: Se debe considerar de forma sistemática la detección precoz de la NIA en poblaciones de riesgo conocidas. Cualquier anormalidad citológica debe ser biopsiada. El ácido tricloroacético puede ser un tratamiento efectivo consiguiendo un alto porcentaje de regresión, aunque actualmente la información con la que contamos es de bajo nivel de evidencia. (AU)

Introduction: Anal intraepithelial neoplasia (AIN) is a premalignant lesion of anal squamous cell carcinoma. HIV-positive males who have sex with males, are the most affected at-risk population. Cytology and anuscopy are the best accepted methods for its diagnosis, although it is controversial which patients should complete it with a biopsy. Neither which patients should undergo treatment nor which is the best treatment is not well established. With this study, we would like to present our experience in the diagnostic-therapeutic management of AIN in the short term. Methods: Retrospective observational study of patients at risk of AIN with altered anal cytology who underwent high-resolution anuscopy with biopsy. After histological confirmation of dysplasia, they started treatment with trichloroacetic acid. Its effectiveness was verified by subsequent cytology. The demographic variables of the sample and the results of both diagnostic and treatment tests were analyzed. Results: The majority were HIV-positive males (104/115) and 50% had sexual relations with other men. We included 115 patients with altered anal cytology, of whom 92% had dysplasia on biopsy. 97% with atypia of uncertain significance on cytology had histological dysplasia. Cytology normalized after treatment in 60% of patients. Conclusion: Early detection of AIN should be routinely considered in known at-risk populations. Any cytological abnormality should be biopsied. Tricholoroacetic acid can be an effective treatment achieving a high percentage of regression, although currently, the information we have is of low level of evidence. (AU)

Does an eHealth Intervention Reduce Complications and Healthcare Resources? A mHeart Single-Center Randomized-Controlled Trial.

(1) Background: In the mHeart trial, we showed that an eHealth intervention, mHeart, improved heart transplant (HTx) recipients' adherence to immunosuppressive therapy compared with the standard of care. Herein, we present the analysis assessing whether mHeart reduces complication frequency and healthcare resource use, and whether this reduction depends on patients' adherence. (2) Methods: The mHeart was a single-center randomized-controlled trial (IIBSP-MHE-2014-55) in 134 adult HTx recipients (n = 71 intervention; n = 63 controls). The endpoints were mortality, complications, and resource use during follow-up (mean 1.6 ± 0.6 years). (3) Results: A significantly lower proportion of HTx recipients in mHeart had echocardiographic alteration (2.8% vs. 13.8%; p = 0.02), cardiovascular events (0.35% vs. 2.4%; p = 0.006), infections (17.2% vs. 56%; p = 0.03), and uncontrolled Hba1c (40.8% vs. 59.6%; p = 0.03) than controls. In addition, a significantly lower proportion of patients in the intervention needed hospital (32.4% vs. 56.9%; p = 0.004) or urgent admissions (16.9% vs. 41.4%; p = 0.002) and emergency room visits (50.7% vs. 69.0%; p = 0.03). Adherence status (measured by the self-reported SMAQ) influenced only controls regarding hospitalizations and emergency room visits. Differences were not significant on deaths (intervention 4.2% vs. control 9.5%; p = 0.4) (4) Conclusions: the mHeart strategy significantly reduced the occurrence of the studied post-transplant complications and the need for medical attention in HTx recipients. Adherence status influenced controls in their need for medical care.

Microfluidic-based dynamic BH3 profiling predicts anticancer treatment efficacy.

Precision medicine is starting to incorporate functional assays to evaluate anticancer agents on patient-isolated tissues or cells to select for the most effective. Among these new technologies, dynamic BH3 profiling (DBP) has emerged and extensively been used to predict treatment efficacy in different types of cancer. DBP uses synthetic BH3 peptides to measure early apoptotic events ('priming') and anticipate therapy-induced cell death leading to tumor elimination. This predictive functional assay presents multiple advantages but a critical limitation: the cell number requirement, that limits drug screening on patient samples, especially in solid tumors. To solve this problem, we developed an innovative microfluidic-based DBP (µDBP) device that overcomes tissue limitations on primary samples. We used microfluidic chips to generate a gradient of BIM BH3 peptide, compared it with the standard flow cytometry based DBP, and tested different anticancer treatments. We first examined this new technology's predictive capacity using gastrointestinal stromal tumor (GIST) cell lines, by comparing imatinib sensitive and resistant cells, and we could detect differences in apoptotic priming and anticipate cytotoxicity. We then validated µDBP on a refractory GIST patient sample and identified that the combination of dactolisib and venetoclax increased apoptotic priming. In summary, this new technology could represent an important advance for precision medicine by providing a fast, easy-to-use and scalable microfluidic device to perform DBP in situ as a routine assay to identify the best treatment for cancer patients.

Polyphenol Intake in Pregnant Women on Gestational Diabetes Risk and Neurodevelopmental Disorders in Offspring: A Systematic Review.

The intake of foods containing polyphenols can have a protective role to avoid comorbidities during pregnancy and, at the same time, promote transgenerational health. This review aims to describe the effect of polyphenol intake through supplements or polyphenol-rich foods during pregnancy on the incidence and evolution of gestational diabetes mellitus (GDM), as well as the link with the neurodevelopment of the fetus. Using PRISMA procedures, a systematic review was conducted by searching in biomedical databases (PubMed, Cinahl and Scopus) from January to June 2022. Full articles were screened (n = 419) and critically appraised. Fourteen studies were selected and were divided into two different thematic blocks considering (i) the effect of polyphenols in GDM and (ii) the effect of GDM to mental disorders in the offspring. A positive relationship was observed between the intake of polyphenols and the prevention and control of cardiometabolic complications during pregnancy, such as GDM, which could be related to thwarted inflammatory and oxidative processes, as well as neuronal factors. GDM is related to a greater risk of suffering from diseases related to neurodevelopment, such as attention deficit hyperactivity disorder, autism spectrum disorder and learning disorder. Further clinical research on the molecule protective mechanism of polyphenols on pregnant women is required to understand the transgenerational impact on fetal neurodevelopment.

Inhaled Loxapine as a Rapid Treatment for Agitation in Patients with Personality Disorder: A Prospective Study on the Effects of Time.

Objective: Agitation in patients diagnosed with personality disorders (PD) is one of the most frequent crises in emergency departments (ED). Although many medications have been tested, their effectiveness has been small or non-significant, and no specific drugs are supported by the available evidence. This study aimed to evaluate the efficacy of Inhaled loxapine (IL) as a therapeutic option for agitated patients with PD. Methods: A naturalistic, unicentric, prospective study was carried out. Thirty subjects diagnosed with PD and attending the ED with episodes of agitation were recruited most of whom were women diagnosed with Borderline Personality Disorder. Subjects were treated with a single dose of IL (9.1 mg). Efficacy was assessed with the Clinical Global Impression scale, the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). Patients were followed 60 minutes after administration to measure IL effect and its duration. Results: IL exhibited an overall efficacy in managing mild to severe agitation, with a quick onset of effect and persistence. 'Effect of time', where IL efficacy is maintained over time, is more marked in higher-severity agitation. No additional treatments were needed to improve agitation during the follow-up time. Conclusion: Results suggest that IL could be a safe and effective option to manage agitation in PD.

Safety of primary immunization with a DTwP-HBV/Hib vaccine in healthy infants: a prospective, open-label, interventional, phase IV clinical study.

OBJECTIVE: This study aimed to assess the safety of a fully liquid DTwP-HBV/Hib pentavalent vaccine (EupentaTM) based on the occurrence of adverse events (AEs) following vaccination. METHODS: This was a prospective, open-label, single-arm, interventional phase IV study. A single intramuscular injection of the study vaccine was administered to infants at approximately 6, 10, and 14 weeks of age, and an end-of-study follow-up visit was scheduled at 18 weeks. RESULTS: In all, 3000 subjects were enrolled and received at least one dose of the study vaccine. Of these, 2717 (90.6%) experienced at least one AE. Immediate reactions, solicited and unsolicited AEs were respectively identified in 224 (7.5%), 2,652 (88.4%), and 1,099 (36.6%) subjects. The most prevalent solicited and unsolicited AEs comprised pain/tenderness and upper respiratory tract infection, respectively. Most AEs were mildly or moderately severe. Forty-one (1.4%) subjects had at least one serious AE (SAE); of these, two (0.1%) had two SAEs each, considered related to the study vaccine. Six (0.2%) subjects died due to unsolicited AEs, none of which were considered related to the study vaccine. No AEs were reported at the end-of-study follow-up visit. CONCLUSIONS: The study vaccine  had a safety profile similar to that reported in a previous clinical study, and did not result in an increased risk of AEs known to be associated with DTwP-based vaccines or previously unrecognized SAEs.
