ArticleTeaching Patients to Self-Care for Active, Recurrent Periodontal or Peri-Implant Pockets Guided by the TIME Wound-Healing Model: A Pilot Feasibility Study Based on Clinical and Microbiological Outcomes(Dove Medical Press, 2026-04-29) Miranda i Rius, Jaume; Àlvarez, Gerard; Blanc, Vanessa; León, Rubén; Ramírez Rámiz, Albert; Brunet i Llobet, LluísWe aimed to evaluate the clinical and microbiological changes recorded after implementation of this personalized subgingival model. Methods: Twelve patients with active periodontal or peri-implant pockets were recruited for a feasibility study. Patients were instructed to deeply clean these lesions subgingivally using an angulated interdental brush in a vertical position, twice per day for 15 days. On the first and last days, Löe & Silness gingival index and bleeding on probing (BoP) were recorded and samples were collected using the brush head for the quantitative PCR analysis of 8 bacterial species (commensal and pathogenic). Results: Severe gingival inflammation with profuse bleeding was present at baseline in ten patients. Eight of them complied and adhered with 100% of the treatment. Following self-treatment at home, ten patients exhibited normal or mildly inflamed gums. Seven patients no longer had bleeding, four had slight bleeding and only one moderate bleeding. Microbiologically, the total bacterial load significantly decreased from 7E07 to 9.39E06 cfu/head. Conclusion: This proposed conservative cost-effective subgingival model could significantly improve the inflammatory activity of certain recurrent periodontal or peri-implant pockets, stabilize them and thus minimize their progression.- ArticleUpgrading and expanding the electro-Fenton and related processes.(Elsevier B.V., 2021-01-05) Sirés Sadornil, Ignacio; Brillas, EnricThe Fenton-based electrochemical advanced oxidation processes are currently recognized as the most effective technologies to achieve fast and complete degradation of target organic contaminants in water. Electro-Fenton was the pioneering process, but a larger mineralization is attained via UV and solar photoelectro-Fenton processes due to the occurrence of key photoreduction reactions. In practice, the decontamination effectiveness turns out to be limited as solution pH increases and the two-electron oxygen reduction reaction occurring at the cathode becomes inefficient or insufficient. Here, we focus on the current opinion in two crucial features of the reviewed processes: (i) trends in cathodic H2O2 electrogeneration, showing the oxygen reduction reaction upgrading upon use of new and/or more sustainable electrocatalysts, cathode configurations and reactor designs; and (ii) advances in iron-based catalysts, with the main purpose of expanding the application to a much wider pH range, eventually surpassing the classical acidic limitation associated to conventional Fenton's reaction.
- ArticleLa renovada actualidad de las demandas reconvencionales ante el Tribunal Internacional de Justicia(Universidad de Navarra, 2001-03-01) Pons Ràfols, XavierEn apenas año y medio, el Tribunal Internacional de Justicia ha dictado tres providencias considerando que las demandas reconvencionales formuladas por la República Federativa de Yugoslavia en el asunto relativo a la aplicación de la Convención para la prevención y sanción del crimen de genocidio que enfrenta a Bosnia-Herzegovina contra Yugoslavia; por los Estados Unidos de América en el asunto de las plataformas petrolíferas que enfrenta a Irán contra los Estados Unidos; y por Nigeria en el asunto de la frontera terrestre y marítima entre Camerún y Nigeria eran admisibles como tales y que pasaban a formar parte de los procedimientos en curso.
- ArticleContinuous glucose monitoring before and after simultaneous pancreas-kidney transplantation: Insights from a real-world clinical setting.(Springer, 2026-04) Amor Fernández, Antonio; Solà, Clara; Ventura Aguiar, Pedro; Serés Noriega, Tonet; Montagud Marrahi, Enrique; Antón, Nerea; Claro, Maria; Figueras Roca, Marc; Ruiz, Montserrat; Ferrer Fàbrega, Joana; Rull Ortuño, Antonio Ramón; Musquera i Felip, Mireia; Diekmann, Fritz; Esmatjes Mompó, EnricIntroduction Simultaneous pancreas–kidney (SPK) transplantation normalizes glycemia in patients with diabetes and end-stage kidney disease, yet data on continuous glucose monitoring (CGM) remain scarce. Methods We retrospectively analyzed CGM metrics in SPK recipients using FreeStyle Libre 2®, comparing pre- and post-transplant profiles. Results Among n = 19 recipients, only n = 14 continued CGM use after transplantation (n = 9 continuously during the entire study period). Within 1 month, all CGM metrics improved significantly, including increased time-in-range (54.21 vs. 83.85%) and time-in-tight-range (TITR; 33.45 vs. 69.77%), and reduced glucose variability (p < 0.05 for all comparisons), with stability over 24 months. Optimal graft function was associated with superior CGM outcomes, notably higher TITR and lower mean amplitude of glycemic excursions (MAGE; p < 0.05). However, hypoglycemia-related targets were not consistently achieved despite otherwise optimal graft performance. Conclusions SPK transplantation was linked to rapid and sustained improvement in CGM profiles. These findings underscore CGM’s value for monitoring graft function and support its integration into post-transplant care to optimize metabolic outcomes.
