  • Anorectal melanoma: a rare entity
    Publication . Relvas, Luís Miguel; Gago, Tânia; Velasco, Francisco; Barros, Sónia; Carvalho, Isabel; Caldeira, Paulo
    Anorectal melanoma is a rare malignant tumor with the potential of simulating a benign anorectal disease, making its diagnosis difficult. We describe a case of anorectal melanoma, in which the interpretation of symptoms as hemorrhoidal disease delayed diagnosis and appropriate intervention.

  • Commentary on: nurses’ perceptions of artificial intelligence (AI) integration into practice: an integrative review
    Publication . Xavier, Tânia; Oliveira, Claudia
    We are writing this letter to congratulate you on the paper ‘Nurses’ perceptions of artificial intelligence (AI) integration into practice: An integrative review’ by Lora and Foran, recently published in your journal. In this paper the authors synthesise remarkable, valuable and challenging aspects of the new era of artificial intelligence (AI) in the clinical practice of nursing. AI has been introduced into the most diverse areas of knowledge, opening a vast range of possibilities. This integrative review makes a timely and relevant contribution to the growing body of literature on the intersection between nursing and AI. The authors show that the practice of nursing, especially in the perioperative environment, is no exception.

  • Gastric mixed neuroendocrine/non-neuroendocrine neoplasia: a rare entity
    Publication . Costa, José Damasceno e; Costa, Rita Seara; Moreira, Hélder Deveza; Ferreira, Aníbal
    Gastric neoplasms have different histological subtypes. Mixed neuroendocrine/non neuroendocrine neoplasms (MiNEN), as defined by the World Health Organization (WHO) 2019 Classification of Tumours of the Digestive System, are rare composite tumours bearing morphological characteristics of more than one histological type. Historically, the diagnosis requires that each component accounts for at least 30% of the total tumour burden. We present the case of a 70-year-old male, who was referred to our endoscopy unit for resection of a depressed lesion (Paris classification type 0 IIc) of 40mm in largest diameter, located on the lesser curvature of the gastric body. The lesion was submitted to en bloc resection by endoscopic submucosal dissection. Histological examination revealed a poorly differentiated intramucosal adenocarcinoma and a grade G3 well differentiated neuroendocrine tumour (NET), on a background of chronic atrophic gastritis. Unfortunately, examination of the NET component revealed intercepted margins. The patient is currently undergoing tumour staging and will be discussed by a multidisciplinary team to determine subsequent management.

  • Letter to the editor: robustness of osteoporosis risk prediction models with enhanced statistical analyses
    Publication . Pires de Carvalho, Filipe Ricardo; Gavaia, Paulo
    In response to Oka et al.’s letter, we conducted additional statistical analyses to validate the robustness of our osteoporosis risk prediction model using NHANES 2007–2014 data (n = 7924). We evaluated 10 key predictors through Spearman’s rho, Kendall’s tau, Mutual Information (MI), and Total Correlation. Weight (BMX_BMXWT) and arm circumference (BMX_BMXARMC) showed strong negative correlations with osteoporosis risk (rho: 0.49, 􀀀 0.47, p < 1e-270; MI: 0.17, 0.15), while age (DEMO_RIDAGEYR) exhibited a positive correlation (rho: 0.33, p < 1e-128; MI: 0.08). Total Correlation (32.68) confirmed significant multivariate interactions among predictors. These findings reinforce the model’s predictive strength, addressing Oka et al.’s recommendations and affirming the importance of anthropometric and demographic factors in osteoporosis risk assessment.

  • Minimally invasive surgery for inflammatory Bowel Disease: a systematic review and meta-analysis of robotic versus laparoscopic surgical techniques
    Publication . Cunha, Miguel F.; Roseira, Joana
    We read with great interest the article ‘Minimally invasive surgery for inflammatory bowel disease: a systematic review and meta-analysis of robotic versus laparoscopic surgical techniques’, recently published in the Journal of Crohn’s and Colitis. 1 Zaman and colleagues performed the first comprehensive systematic review and meta-analysis to examine the outcomes of robotic versus conventional laparoscopic colorectal resections in patients with inflammatory bowel disease [IBD], focusing on the comparative effectiveness, safety pro files, and surgical performance metrics of these two minimally invasive approaches.

  • Pantoprazole-induced liver injury in the setting of diabetic ketoacidosis
    Publication . de Oliveira, Raquel; Almeida, Manuel; Lavado, Pedro; Baptista, Alexandre
    Critically ill patients are at higher risk of acquired liver in-jury, given the multiple coexisting potential causes of injury.1They are also at risk of stress ulcers, and prophylaxis with proton pump inhibitors (PPIs) is common in Intensive Care Units (ICUs). A 54-year-old woman was admitted to the ICU due to diabetic ketoacidosis (DKA). On admission, she was hemo-dynamically stable, with a Glasgow Coma Scale score of 7 (E2V1M4). Her abdominal examination was normal, without palpable organomegalies, and her liver blood tests were within the normal range. She was intubated for airway pro-tection and started on intravenous fluids, insulin perfusion, and prophylaxis with intravenous pantoprazole 40 mg/day.

  • Possible role of mycotoxins, malnutrition and MECP2 dysregulation in nodding syndrome
    Publication . Catamo Vaz, Deise Haua da Silva; Costa, Maria Helena da; Buque, Helena Agostinho; Nzwalo, Hipólito
    We read with great interest the manuscript by Spencer et al. [1] suggesting a possible role of Methyl-CpG-binding protein 2 (MECP2) dysregulation in the pathogenesis of Nodding syndrome (NS), a childhood onset epileptic disorder occurring exclusively in sub-Saharan Africa. The sociodemographic and phenotypic overlap of NS with MECP2 duplication syndrome, namely the age of onset interval, female predominance;

  • Pregnancy outcomes in systemic sclerosis: experience of a rheumatology-obstetric multidisciplinary clinic
    Publication . Chícharo, Ana Teodósio; Lopes, Ana Rita; Barreira, Sofia; Martins, Patrícia; Machado, Ana Rita Cruz; Pinto, Luísa; Capela, Susana
    Systemic sclerosis (SSc) is a rare multisystemic connective tissue disease (CTD). It is mainly characterized by progressive fibrosis and non-inflammatory vasculopathy. Women diagnosed with SSc seem to be at increased risk of developing adverse pregnancy outcomes (APO), but maternal and perinatal outcomes remain poorly understood in these patients, with no data yet available from Portuguese centers.

    Phytophthora is a long-established, well-known, and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from Phytophthora at least twice. Because, cladistically, this renders Phytophthora “paraphyletic,” it has been proposed that Phytophthora evolutionary clades be split into multiple genera (Crous et al. 2021; Runge et al. 2011; Thines 2023, 2024). In this letter, we review arguments for the retention of the generic name Phytophthora with a broad circumscription made by Brasier et al. (2022) and by many delegates at an open workshop organized by The American Phytopathological Society. We present our well-considered responses to the genus splitting proposals, both in general terms and in terms of the specific proposals for new genera, alongside new information regarding the biological properties and mode of origin of the Phytophthora clades. We consider that the proposals are mostly non-rigorous and not supported by the scientific evidence. Further, given (i) the apparent lack of any distinguishing biological characteristics (synapomorphies) between the Phytophthora clades; (ii) the fundamental monophyly of Phytophthora in the original Haeckelian sense (Haeckel 1877); (iii) the fact that paraphyly is not a justification for taxonomic splitting; and (iv) the considerable likely damage to effective scientific communication and disease management from an unnecessary breakup of the genus, we report that workshop delegates voted unanimously in favor of preserving the current generic concept and for seeking endorsement of this view by a working group of the International Commission on the Taxonomy of Fungi.
