    FCT_UIDB/05608/2020. FCT_UIDP/05608/2020.Inflammatory bowel disease (IBD) is characterized by a chronic and relapsing inflammatory response in the gastrointestinal tract, resulting in severe symptoms such as abdominal pain, vomiting, diarrhea, bloody stools, and weight loss. Currently, there is no cure, and the pharmacological treatment includes drugs that induce and keep the patient in remission, not reversing the underlying pathogenic mechanism. In the long term, these therapies may cause various side effects and complications, which has increased the need to investigate new, more effective, and safer pharmacological approaches. In preclinical studies, topiramate has demonstrated a potential anti-inflammatory effect by inhibiting the production of several pro-inflammatory cytokines. This study aimed to investigate the effect of topiramate in a chronic TNBS-induced colitis model in rodents. Experimental colitis was induced by four intrarectal administrations of 1% TNBS in female CD-1 mice. Topiramate 10 and 20 mg were administered intraperitoneally for 14 days. Several parameters were evaluated, such as body weight, alkaline phosphatase (ALP), fecal hemoglobin, fecal calprotectin, tumor necrosis factor (TNF)-α, and interleukin (IL)-10. Topiramate reduces TNBS-induced colonic damage in a model of chronic experimental colitis and normalizes stool consistency and anus appearance. Additionally, topiramate significantly reduced the concentration of ALP, fecal hemoglobin, fecal calprotectin, TNF-α, and IL-10, demonstrating it to be a promising pharmacological approach for treating IBD in the future.info:eu-repo/semantics/publishedVersio

This is an open access article under the CC-BY-NC-ND license.Introduction: Valvular heart disease (VHD) is increasing worldwide, mostly because of aging. Percutaneous valve intervention is the preferred therapeutic option in high-risk patients. Objective: To characterize the profiles of patients with VHD admitted to the cardiology ward at a tertiary referral center. Methods: On the basis of ICD-9 codes for VHD, the discharge notes of 287 patients hospitalized over a 22-month period were reviewed and analyzed. One hundred characteristics were considered. Results: Median age was 74 (23-93) years, and 145 (51%) were male. The admissions were elective (for valve intervention) in 36%. Heart failure (HF) was the reason for urgent admissions in 29.3%. Multiple comorbidities were observed in 53% of patients. Etiology of VHD was degenerative in 68%, functional in 15.3% and rheumatic (predominantly in women and younger patients) in 8.7%. Aortic valve disease was present in 63% (aortic stenosis in 56%), and was associated with HF (p=0.004), atrial fibrillation (AF) (p=0.01), and left ventricular (LV) dilatation (p=0.003) or hypertrophy (p<0.001). Mitral valve disease (51%), mostly mitral regurgitation (degenerative or functional), predominated in women, and was associated with HF, AF, LV dilatation (p<0.001) and reduced LV ejection fraction (p=0.003). Significant tricuspid regurgitation (34.8%) associated with the presence of previously implanted cardiac devices (p<0.001). Valve intervention (mostly transcatheter aortic valve implantation) was performed in 41% of patients. Mean length of hospital stay was 12±14.3 days and overall in-hospital mortality was 9.8%.info:eu-repo/semantics/publishedVersio

    Improving the interface between orthopaedic implants and bone - a comparison between different surface treatments

    Get PDF
    Apresentação efetuada em "Junior Euromat 2022", em Coimbra, 2022Orthopedic implants for load-bearing applications are usually composed of titanium-based materials. However, insufficient bioactivity of metallic materials impairs the bonding with bone, compromising osseointegration at an early stage. The implant-bone interface may be improved by regulating some surface properties of the biomaterials, including surface chemical composition, surface energy, roughness and topography, which influence the behavior of bone cells. In the present study, commercially pure titanium and Ti6Al4V alloy were used to investigate the effect of three surface treatments, after performing two different chemical pre-treatments, on the characteristics of the obtained oxide films. Regarding the pre-treatments, no major differences were observed between performing alcohol cleaning or acidic pre-treatment, considering the surface crystallinity, roughness and wettability. However, the TiO2 layer formed upon anodic oxidation, hydrothermal treatment and anodic oxidation followed by hydrothermal treatment presented different characteristics regarding its crystallinity, roughness, thickness and wettability. This study compared specific surface treatments and the hydrothermal treatment is proposed as a simple treatment capable of improving the characteristics of the implant surface, thereby promoting osteoconductivity. In fact, the culture of human Mesenchymal Stem Cells on Ti-based materials subjected to hydrothermal treatment and consequent induction of osteogenic differentiation confirm the improved surface characteristics.This work was supported by FCT (Fundação para a Ciência e a Tecnologia) through the grant SFRH/BD/141056/2018 and the projects PTDC/EME-EME/1442/2020, POCI-01-0145-FEDER-030498, UIDB/04436/2019 and UIDP/04436/2020.

    Robust gap repair in the contractile ring ensures timely completion of cytokinesis

    Get PDF
    Cytokinesis in animal cells requires the constriction of an actomyosin contractile ring, whose architecture and mechanism remain poorly understood. We use laser microsurgery to explore the biophysical properties of constricting rings in Caenorhabditis elegans embryos. Laser cutting causes rings to snap open. However, instead of disintegrating, ring topology recovers and constriction proceeds. In response to severing, a finite gap forms and is repaired by recruitment of new material in an actin polymerization-dependent manner. An open ring is able to constrict, and rings repair from successive cuts. After gap repair, an increase in constriction velocity allows cytokinesis to complete at the same time as controls. Our analysis demonstrates that tension in the ring increases while net cortical tension at the site of ingression decreases throughout constriction and suggests that cytokinesis is accomplished by contractile modules that assemble and contract autonomously, enabling local repair of the actomyosin network. Consequently, cytokinesis is a highly robust process impervious to discontinuities in contractile ring structure.European Research Council grant: (640553); Fundo Europeu de Desenvolvimento Regional (FEDER) funds: (Operational Competitiveness Program - COMPETE); Fundação para a Ciência e a Tecnologia grant:(NORTE-07-0124-FEDER-000003); Fundação Luso-Americana para o Desenvolvimento (Life Science 2020); Louis-Jeantet Young Investigator Award; European Social Fund (Programa Operacional Temático Potencial Type 4.2); Programa Operacional Regional do Norte (Quadro de Referência Estratégico Nacional - FEDER).info:eu-repo/semantics/publishedVersio

Our study compared the effectiveness of two empowerment-based approaches toward blood pressure (BP) reduction: salt reduction-specific program vs. healthy lifestyle general program. Methods: Three hundred and eleven adults (median age of 44 years, IQR 34–54 years) were randomly assigned to a salt reduction (n = 147) or a healthy lifestyle program (n = 164). The outcome measures were urinary sodium (Na+) and potassium (K+) excretion, systolic (SBP) and diastolic (DBP) blood pressure, weight, and waist circumference. Results: There were no significant differences in primary and secondary outcomes between the two program groups. When comparing each program to baseline, the program focused on salt reduction was effective in lowering BP following a 12-week intervention with a mean change of −2.5 mm Hg in SBP (95% CI, −4.1 to −0.8) and − 2.7 mm Hg in DBP (95% CI, −3.8 to −1.5) in the intention-to-treat (ITT) analysis. In the complete-case (CC) analysis, the mean change was −2.1 mm Hg in SBP (95% CI, −3.7 to −0.5) and − 2.3 mm Hg in DBP (95% CI, −3.4 to −1.1). This effect increases in subjects with high-normal BP or hypertension [SBP − 7.9 mm Hg (95% CI, −12.5 to −3.3); DBP − 7.3 mm Hg (95% CI, −10.2 to −4.4)]. The healthy lifestyle group also exhibited BP improvements after 12 weeks; however, the changes were less pronounced compared to the salt reduction group and were observed only for DBP [mean change of −1.5 mm Hg (95% CI, −2.6 to −0.4) in ITT analysis and − 1.4 mm Hg (95% CI, −2.4 to −0.3) in CC analysis, relative to baseline]. Overall, improvements in Na+/K+ ratio, weight, and Mediterranean diet adherence resulted in clinically significant SBP decreases. Importantly, BP reduction is attributed to improved dietary quality, rather than being solely linked to changes in the Na+/K+ ratio. Conclusion: Salt-focused programs are effective public health tools mainly in managing individuals at high risk of hypertension. Nevertheless, in general, empowerment-based approaches are important strategies for lowering BP, by promoting health literacy that culminates in adherence to the Mediterranean diet and weight reduction.publishersversionpublishe

    INTRODUCTION: Ectopic kidneys with concomitant aortoiliac aneurysmal disease have been previously reported in the literature, however its exact prevalence is unknown. The objective of this review is to summarize current knowledge on the treatment this special group of patients. METHODS: A non-systematic literature research was performed on the treatment of aortoiliac aneurysmal disease in patients with ectopic kidneys. RESULTS: Literature on the management of patients with aorto-iliac aneurysms and concomitant ectopic kidneys is limited to case reports and very small series. Treatment modalities which include open, endovascular or hybrid techniques, should preserve the variable vasculature of the ectopic kidney. Several different surgical solutions have been proposed, highlighting the uncertainty on the optimal management strategy. However, a growing number of reports suggest safety and efficacy with adapted endovascular techniques. CONCLUSION: In parallel to the general trend in the management of abdominal aortic aneurysm, it is expected that a growing number of patients will concomitant aorto-iliac aneurysm and ectopic kidneys will be treated with endovascular techniques

Usage and distribution for commercial purposes requires written permission.Background: Listing patients with alcohol-associated liver disease (ALD) for liver transplant (LT) remains challenging especially due to the risk of alcohol resumption post-LT. We aimed to evaluate post-LT alcohol consumption at a Portuguese transplant center. Methods: We conducted a cross-sectional study including LT recipients from 2019 at Curry Cabral Hospital, Lisbon, Portugal. A pretested survey and a validated Portuguese translation of the Alcohol Use Disorder Identification Test (AUDIT) were applied via a telephone call. Alcohol consumption was defined by patients' self-reports or a positive AUDIT. Results: In 2019, 122 patients underwent LT, and 99 patients answered the survey (June 2021). The mean (SD) age was 57 (10) years, 70 patients (70.7%) were males, and 49 (49.5%) underwent ALD-related LT. During a median (IQR) follow-up of 24 (20-26) months post-index LT, 22 (22.2%) recipients consumed any amount of alcohol: 14 had a drink monthly or less and 8 drank 2-4 times/month. On drinking days, 18 patients usually consumed 1-2 drinks and the remainder no more than 3-4 drinks. One patient reported having drunk ≥6 drinks on one occasion. All post-LT drinking recipients were considered low risk (score <8) as per the AUDIT score (median [IQR] of 1 [1-2]). No patient reported alcohol-related problems, whether self-inflicted or toward others. Drinking recipients were younger (53 vs. 59 years, p = 0.020), had more non-ALD-related LT (72.7 vs. 44.2%, p = 0.018) and active smoking (31.8 vs. 10.4%, p = 0.037) than abstinent ones. Conclusion: In our cohort, about a quarter of LT recipients consumed alcohol early posttransplant, all with a low-risk pattern according to the AUDIT score.publishersversionepub_ahead_of_prin
