- G2P[4] the most prevalent rotavirus genotype in 2007 winter season in an European non-vaccinated populationPublication . Antunes, H; Afonso, A; Iturriza, M; Martinho, I; Ribeiro, C; Rocha, S; Magalhães, C; Carvalho, L; Branca, F; Gray, JBACKGROUND: Recently, a high prevalence of G2P[4] rotavirus (RV) infection was reported from Brazil, and linked with the universal RV vaccination programme that used the G1P[8] live oral RV vaccine. OBJECTIVE: To determine the genotypes of RV co-circulating in a non-vaccinated population, in northern Portugal in the winter season of 2007. STUDY DESIGN: Prospective multicenter study of the genotypes circulating in the northwest region of Portugal during January to March 2007. Children with acute gastroenteritis, who attended the Pediatric Emergency Services of five Hospitals, were included in the study. The parents of the children completed a clinical and epidemiological data questionnaire and stool samples were collected. Stool samples positive in a RV enzyme immunoassay (EIA) were genotyped by reverse transcriptase-polymerase chain reaction. RESULTS: Stool samples were collected from 424 children. Two hundred and thirty-four (55.2%) stool samples were RV-positive. G2P[4] was the predominant RV type (68.6%), followed by G9P[8] (14.0%). CONCLUSIONS: Because our population was naïve for RV vaccine, the G2P[4] predominance cannot be explained by vaccination. Rather, this high prevalence of G2P[4] may be within the normal fluctuation of RV genotypes. RV strain surveillance programmes are important for informing RV vaccination programmes.
- Mental health-promoting intervention models in university students: a systematic review and meta-analysis protocolPublication . Amaro, P; Fonseca, C; Pereira, A; Afonso, A; Barros, M L; Serra, I; Marques, M F; et al.Background The transition to higher education represents a demanding adaptation process with several socioeconomic factors involved. Mental health problems among university students have been worsening since the beginning of the COVID-19 pandemic. Our objective is to create scientific evidence about the models of mental health-promoting interventions among higher education students applied in academic environments, as well as their effectiveness. We aim to synthesise the scientific evidence on the models of an intervention promoting mental health among university students applied in academic environments as well as their results. Methods and analysis A systematic review of the literature will be conducted. The research will be carried out using the EBSCO databases (CINAHL Complete, MEDLINE Complete, Psychology and Behavioral Sciences Collection), PubMed and Scopus. The research strategy includes the following MeSH or similar terms: Universities [Mesh], Students [Mesh], Education [Mesh], Undergraduate, “Higher Education”, Universit*, College, Student*; “Psychosocial intervention” [Mesh], “Non-pharmacological”, “Intervention model*“, “Mental health promotion program*“, Intervention*; “Randomized Controlled Trial”, RCT; “Mental health” [Mesh], Depression [Mesh], Anxiety [Mesh], “Stress, psychological” [Mesh], “Quality of life” [Mesh], and “Psychological well-being” [Mesh]. All experimental studies with mental health-promoting interventions for university students that were published between January 2017 and November 2024 in English will be eligible. Two independent reviewers will apply the inclusion and exclusion criteria, analyse the quality of the data and extract it for synthesis. Disagreements will be resolved by a third reviewer. All randomised controlled trial studies with interventions in university students and their efficacy (with means and SD) will be included in the systematic review of the literature. The standardised mean difference will be used as the effect size to standardise individual results. Sensitivity analysis, subgroup analysis and meta-regression will be conducted to explore the causes of heterogeneity and the robustness of the results. Ethics and dissemination Ethical approval is not required for this study as it is based on the review of previously published data. The results will be disseminated through publication in peer-reviewed journals and presentations at academic conferences, as well as in events organised by student associations
- Pazopanib-Induced Cutaneous Leukocytoclastic Vasculitis: An Exclusion Diagnosis of a Multidisciplinary ApproachPublication . Alpuim Costa, D; Baptista de Almeida, S; Coelho Barata, P; Quintela, A; Cabral, P; Afonso, A; Maia Silva, JIn phase II/III trials, cutaneous side effects of pazopanib were reported in less than 20% of patients, with only 1–3% being grade 3/4. We present a case of a 66-year-old man with a previous history of left nephrectomy for a stage II clear cell renal carcinoma. Approximately 18 months later, recurrent disease in the lungs, mediastinum, and left psoas and bulky abdominal/pelvic nodal metastasis were documented. He was initially treated with pazopanib 800 mg q.d. and 1 week after starting this therapy, the patient presented with palpable purpura on his ankles. These lesions regressed within 2 weeks off pazopanib, but had recurred 4 weeks after he resumed medication at 400 mg q.d. Biopsy of the lesions revealed leukocytoclastic vasculitis. Despite tumour response to therapy, pazopanib was discontinued with total resolution of this skin toxicity within 2 weeks of his cutaneous toxicity. To the best of our knowledge, we report a rare yet significant cutaneous adverse reaction to pazopanib.
- Schwannoma, a rare tumor of the seminal vesiclePublication . Furtado, AM; Carrasquinho, E; Ferreira, M; Afonso, A; Ferrito, FWe present a rare case of a schwannoma of the seminal vesicle that occurred in a 43-year-old male with symptoms of the lower urinary tract. Ultrasonography and magnetic resonance imaging documented a solid mass in the patient's left seminal vesicle. A transvesical approach with a transtrigonal midline incision was successfully performed. The microscopic aspect was compatible with schwannoma.
