Título: Influência do polimorfismo rs9939609 do gene FTO nos dados clínicos e comportamento nutricional de pacientes submetidos à cirurgia bariátrica em um hospital público de referência no Maranhão Autor: SANTIAGO, Andréa Karine de Araújo Primeiro orientador: VIDAL, Flávia Castello Branco Abstract: Introduction: Obesity is a multifactorial condition resulting from the interaction between genetic predisposition and environmental factors. Among genetic markers, the Fat Mass and Obesity-Associated (FTO) gene stands out due to its strong association with increased Body Mass Index (BMI) and risky eating behaviors. Objective: To investigate the influence of the rs9939609 polymorphism of the FTO gene on clinical aspects and eating behavior in patients undergoing bariatric surgery at a public referral hospital in Maranhão. Methods: This was an ambispective longitudinal cohort study including 98 patients who underwent bariatric surgery. Preoperative clinical and anthropometric data were obtained from medical records, while postoperative data were collected through direct assessment to calculate weight loss and weight regain indicators. Behavioral factors were assessed using a structured questionnaire based on the Three-Factor Eating Questionnaire (TFEQ-R21) and a Food Frequency Questionnaire. Oral mucosa samples were collected for DNA extraction and genotyping of the rs9939609 polymorphism of the FTO gene using qPCR. Statistical analyses included association tests, comparisons between genotype groups, and assessment of Hardy–Weinberg equilibrium (p<0.05). Results: The frequency of the risk allele “A” was 40.8%, with a predominance of the heterozygous genotype AT (51.0%). No statistically significant associations were observed between genotypes (AA/AT vs. TT) and percentage weight loss or postoperative BMI (p>0.05). However, a trend toward greater weight regain was identified in carriers of the risk allele (9.9% ± 5.5%) compared to the wild-type genotype (7.2% ± 8.3%), although strongly correlated with follow-up time (p<0.001). Conclusion: The rs9939609 polymorphism of the FTO gene showed an influence on weight regain after bariatric surgery, with no significant impact observed on eating behavior, clinical characteristics, weight loss, or remission of comorbidities in this population.

Título: Perfil das Pacientes com Dor Pélvica Crônica e Endometriose em São Luis do Maranhão Autor: MELO, Marilu Marques de Primeiro orientador: LEAL, Plinio da Cunha Abstract: Introduction: Chronic pelvic pain associated with endometriosis is a frequent, multifactorial, and debilitating condition that compromises quality of life, functional performance, and reproductive health. Despite its clinical relevance, there are still few national studies that comprehensively describe the clinical, epidemiological, and psychosocial profile of these patients, as well as the overlap of comorbidities and central pain sensitization mechanisms. Objective: To outline the sociodemographic, reproductive, clinical, and psychosocial profile of women with chronic pelvic pain treated at a high-complexity hospital in São Luís, Maranhão, comparing those with and without endometriosis, and characterizing the intensity, mechanisms, and pain centralization. Methods: This was a prospective, analytical, observational study with a quantitative approach, conducted in the gynecology outpatient clinic of a highcomplexity hospital in São Luís, Maranhão, Brazil, between August 2022 and July 2025. Participants included women ≥18 years old with chronic pelvic pain who underwent investigation with imaging exams and/or videolaparoscopy for the diagnosis of endometriosis. Results: A total of 174 women were included, with a prevalence of endometriosis of 67.2%. Among patients with endometriosis, deep endometriosis in the uterosacral ligaments was observed in 50.5%, with 45.5% in stages 3-4 of the disease. Women with endometriosis had higher levels of education and a higher rate of nulliparity. Dysmenorrhea was widely present among women with endometriosis, while painful and functional comorbidities showed high frequencies in both groups, such as migraine, irritable bowel syndrome, myofascial pain, vulvodynia, and neuropathic pain. Pain centralization showed a predominant distribution of severe to extreme degrees, and most women exhibited symptoms of depression, anxiety, and stress of varying intensities, mainly extremely severe anxiety in 31.3% of patients with endometriosis and 41.9% of those without the disease. Conclusion: Chronic pelvic pain associated with endometriosis is characterized by a strong relationship with dysmenorrhea and nulliparity, as well as an overlap of painful comorbidities and psychological distress.

Título: Papilomatose respiratória recorrente em adultos: uma revisão de escopo Autor: BEZERRA, Andressa Lima Castro Primeiro orientador: CABRAL, Flávia Castello Branco Vidal Abstract: Introduction: Recurrent respiratory papillomatosis is a rare and chronic condition characterized by benign papillomatous lesions in the respiratory tract, commonly associated with human papillomavirus (HPV) genotypes 6 and 11. Adult-onset disease presents a variable clinical course, with frequent recurrence and significant functional impact. Objective: To map the available scientific evidence on adult-onset recurrent respiratory papillomatosis, focusing on epidemiological, clinical, and therapeutic aspects. Methods: This scoping review was conducted in accordance with the Joanna Briggs Institute (JBI) methodology and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) extension (Tricco et al., 2018). Searches were performed between July and September 2025 across PubMed/MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, LILACS, ProQuest, and Google Scholar, yielding 2,079 records. Study selection was performed in two stages, followed by standardized data extraction. Results: The included studies were predominantly observational, mainly conducted in tertiary care settings, and characterized by small to moderate sample sizes. Adult-onset recurrent respiratory papillomatosis predominantly affected young to middle-aged males. Clinically, the disease was marked by dysphonia, frequent recurrence, and the need for repeated surgical interventions. Surgical management remained the cornerstone of treatment, while adjuvant therapies, such as bevacizumab and cidofovir, showed potential benefits despite heterogeneous and limited evidence. Conclusion: The current evidence on adult-onset recurrent respiratory papillomatosis remains fragmented and predominantly observational, with significant gaps in population- based epidemiology, standardized outcomes, and comparative therapeutic effectiveness. There is a need for multicenter studies with robust methodological designs, as well as clinical validation of emerging therapeutic strategies, including immunotherapy and HPV vaccination approaches, which may contribute to reducing recurrence rates and improving patient outcomes.

Título: Análise da associação entre a carga de hipersinal na substância branca e o acidente vascular encefálico isquêmico Autor: SOUSA, Márcia Beatriz Oliveira de Primeiro orientador: OLIVEIRA, Caio Márcio Barros de Abstract: Introduction: Cerebral white matter hyperintensities, which is part of the spectrum of small vessel disease, has been described in the literature as a biomarker for lacunar ischemic stroke. Some studies question its association with more extensive non- lacunar ischemic infarcts. The main objective was to understand this association in a population in the state of Maranhão. Additionally, to observe the association of high signal intensity in cerebral white matter with its main risk factors such as hypertension, obesity, diabetes, and advanced age. Method: Retrospective analysis of 176 brain magnetic resonance imaging (MRI) scans performed at a tertiary public hospital, in a cross-sectional study. The study was conducted between January 2022 and September 2024, including patients of both sexes aged 55 years or older, after approval by the ethics committee. Data were cataloged in an Excel spreadsheet and processed using StataNow 1.8 BE-Basic edition and Jamovi, employing Fisher's exact test, Kruskal-Wallis test, ANOVA with Tukey post-hoc analysis for the parametric variable identified in the Shapiro-Wilk test, logistic regression, and Fleiss's Kappa to verify inter-observer agreement. Results: A statistically significant association was observed between higher hypersignal load in the white matter and lacunar infarcts, but not with more extensive cerebral infarcts. Furthermore, a statistically significant association with age was also detected. Conclusion: In patients with a higher hypersignal load in the cerebral white matter, a greater number of lacunar infarcts are detected, especially in older patients.
