- Ethical and bioethical aspects concerning the disclosure of medical information for a fair reason(2022) RAIMUNDO, Gabrielle Cristina; GRANDO, Lavinia Luiza; MACHADO, Andre Newman Cordeiro; OLIVEIRA, Matheus; CABAR, Fabio RobertoOBJECTIVE: The objective of this study was to emphasize the importance of legal and bioethical knowledge in maintaining medical confidentiality, especially in situations when there is a diagnosis of HIV infection. METHODS: A literature review of studies published in the Scientific Electronic Library Online and National Library of Medicine databases was performed. Sixteen studies available in full, online, and free, published between 2010 and 2020, were selected. RESULTS: The studies highlighted that, despite the ethical duty to breach confidentiality for the protection of third parties, many doctors are reluctant to reveal this secret due to the power of stigmatization and social discrimination related to the diagnosis of HIV infection, which affects integrity, counseling, and capability to treat patients. CONCLUSION: HIV diagnosis implies bioethical and legal questions. Respect for medical confidentiality is a matter to be discussed, as there is a need to protect the privacy of the patient, at the same time the responsibility to preserve the health of others.

- Serum concentration of vascular endothelial growth factor and depth of trophoblastic invasion in ampullary ectopic pregnancy(2016) CABAR, Fabio Roberto; TESHIMA, Decio Roberto Kamio; PEREIRA, Pedro Paulo; ANTONANGELO, Leila; SCHULTZ, Regina; FRANCISCO, Rossana PulcineliOBJECTIVE: To evaluate the association between the depth of trophoblastic infiltration and serum vascular endothelial growth factorconcentration in patients with an ampullary pregnancy. METHODS: This prospective cross-sectionalstudy involved 34 patients with an ampullary ectopic pregnancy who underwent salpingectomy between 2012 and 2013. Maternal serum vascular endothelial growth factor concentrations were measured using Luminex technology. Trophoblastic invasion was classified histologically as follows: stage I, limited to the tubal mucosa; stage II, reaching the muscle layer; and stage III, involving the full thickness. The qualitative data were compared using Fisher's exact test. The nonparametric Kruskal-Wallis and Mann-Whitney tests were used to evaluate differences in serum vascular endothelial growth factor among the degrees of trophoblastic invasion. ROC curves were constructed to determine vascular endothelial growth factor cut-off values that predict the degree of tubal invasion based on the best sensitivity and specificity. RESULTS: Eight patients had stage I trophoblastic invasion, seven had stage II, and 19 had stage III. The median serum vascular endothelial growth factorconcentration was 69.88 pg/mL for stage I, 14.53 pg/mL for stage II and 9.08 pg/mL for stage III, with a significant difference between stages I and III. Based on the ROC curve, a serum vascular endothelial growth factor concentration of 25.9 pg/mL best differentiated stage I from stages II and III with asensitivity of 75.0%, specificity of 76.9%, and area under the curve of 0.798. CONCLUSIONS: The depth of trophoblastic penetration into the tubal wall isassociated with serum vascular endothelial growth factor concentration in ampullary pregnancies.
- Low back pain, pelvic pain, and associated factors in type 1 diabetic pregnant women(2024) BATISTA, Patricia Andrade; OLIVEIRA, Claudia de; COSTA, Rafaela Alkmin da; FRANCISCO, Rossana Pulcineli Vieira; CABAR, Fabio RobertoIntroduction: Pregnancy and diabetes mellitus promote several musculoskeletal changes predisposing this population to complaints of Lower Back (LB) and Pelvic Pain (PP). Objective: To assess the frequency of LB and PP and associated factors in type 1 Diabetic (DM1) pregnant women. Method: An observational analytical cross-sectional study. Thirty-six pregnant women with DM1 were evaluated through a postural assessment with a focus on pelvic positioning and what patients reported. The associated factors were assessed using the State-Trait Anxiety Inventory (STAI), the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Female Sexual Function Index (FSFI). Results: The frequency of LB and PP was 55.6 % and 30.6 %, respectively. The presence of anxiety was not associated with a higher prevalence of pain. The incidence of sexual dysfunctions was higher in the GD. DM1 duration had a mean of 14.9 years (+/- 8.2 SD) in the GD and 9.0 years (+/- 6.9 SD) in the GSD, which was statistically significant (p <= 0.050). In the multiple binary regression analysis for the occurrence of pain, the independent factor was DM1 duration >= 17 years (OR = 11.2; 95 % CI = 1.02-124.75). The association between DM1 duration >= 17 years and being overweight showed a probability of 95 % for the studied population in the analysis of the probabilities of occurrence of the pain event. Conclusion: There was a high frequency of LB and PP related to pregnancy in DM1 pregnant women in the second trimester of pregnancy. The incidence of sexual dysfunction and DM1 duration >= 17 years increases the chance that DM1 pregnant women will experience pain. There was no association between anxiety. urinary incontinence and pain in DM1 pregnant women.
- Expression of matrix metalloproteinases and their inhibitors at the implantation site in ampullary ectopic pregnancies(2021) GOMEZ, Ursula Trovato; BRIZOT, Maria de Lourdes; PEREIRA, Pedro Paulo; RODRIGUES, Agatha Sacramento; SCHULTZ, Regina; HOSHIDA, Mara Sandra; FRANCISCO, Rossana Pulcineli Vieira; CABAR, Fabio RobertoObjective: This study investigated the qualitative and semi-quantitative expression of metalloproteinases (MMP) and their tissue inhibitors (TIMP) in trophoblastic tissue during ampullary ectopic pregnancies and correlated that expression with the degree of tubal invasion. Study design: It is a prospective study that included 34 patients diagnosed with ampullary tubal pregnancy who underwent salpingectomy. A histological evaluation of the depth of trophoblastic invasion in the tubes obtained was performed. Subsequently, the expression of the MMP-2, MMP-9, MMP-14, TIMP-1, TIMP-2 and TIMP-3 markers was qualitatively and semi-quantitatively evaluated by indirect immunohistochemistry. In addition, the degree of trophoblastic invasion was correlated with the expression of each marker and with the metalloproteinase/inhibitor ratios. Results: MMP-2 (11.2 %; 3.6-17.9) was the marker with greater expression at the implantation site, both in the qualitative and semi-quantitative assessment, while MMP-9 (2.23 %; 0.2-5.4) and TIMP-3 (2.53 %; 0.1-15.3) were only weakly expressed. Conclusion: There was wide variation in expression among the markers and metalloproteinase/inhibitor ratios studied compared to the degrees of invasion.
CRIPTO-1 Is Immunolocalized in the Syncytiotrophoblast of Ampullary Pregnancies
(2022) CABAR, Fabio Roberto; PEREIRA, Pedro Paulo; BANDEIRA, Carla Leticia; BEVILACQUA, Estela; SCHULTZ, Regina; FRANCISCO, Rossana Pulcineli VieiraIntroduction. Controlling the invasive activity of trophoblastic tissue has not been elucidated. In the accreta placenta, the invasion of placental tissue is directly related to the expression of CRIPTO-1 at the maternal-fetal interface. The aim of this study is to evaluate if the expression of the CRIPTO-1 is related to different degrees of trophoblast invasion into the tube wall in ampullary pregnancy. Methods. Prospective study with 21 patients with ampullary tubal pregnancy undergoing salpingectomy. Anatomopathological evaluation determined the degree of invasion of trophoblast tissues into the tubal wall and grouped the samples into invasive degrees I, II, or III. The groups were compared for tissue expression of CRIPTO-1 using the Kruskal-Wallis nonparametric test. p values lower than 0.05 were considered significant. Results. Quantitative expression of CRIPTO-1 differed in each of the three groups of trophoblast invasion in the tubal wall in ampullary pregnancies (p < 0.001). There is a difference between groups when grade I + grade II versus grade III (p < 0.001) and grade I versus grade II + grade III (p < 0.001). The tissue expression of CRIPTO-1 in ectopic trophoblasts showed that deeper invasion of the tubal wall was associated with stronger expression than in shallow invasion (p < 0.001). Discussion. In ampullary pregnancies, the depth of penetration of trophoblast tissue in the tubal wall is related to CRIPTO-1 tissue expression.- Bioethical and legal issues of termination of pregnancy resulting from rape(2022) CABAR, Fabio Roberto; FRANCO, Juliana Bertoldi; GORGA, Maria Luiza
- The need to standardize use of the newly deceased in medical trainings(2020) CABAR, Fabio Roberto; LACERDA, Daniele Costa Rachid; FREITAS, Gabriela Thome Souza de; GORGA, Maria LuizaOBJECTIVES: The present study aimed to identify the characteristics of use of the deceased in invasive training and the bioethical principles that govern this practice. In this context, it has become imperative to deduce which professional skills are critical to develop. METHODS: A prospective study investigated a cadaver's use in medical (and related) schools through a questionnaire, which was made available for 48 hours on social networks (Facebook and Linkedln) to groups of doctors and medical students using a communication app (WhatsApp). The inclusion criteria were being a medical student or a doctor. Cases in which the answers to the questionnaire were inadequate, or when the student had reason to withdraw, were excluded. Each participant could only answer the questionnaire once, and could not modify the responses after submitting it. RESULTS: A disproportionate relationship was found regarding the replacement of the newly deceased by other means (such as dummies and simulators). This outcome suggests that there is no substitution, concomitant with the importance of a prior request for consent from the patient and/or subsequent consent from family members. CONCLUSION: According to the findings, the significance of-and need for-training is undeniable. Hence, it is urgent to normalize the practice and definition of the ethical limitations of medical conduct.
- Mother's freedom of choice and the rights of an unborn child: a comparison between the views of freshmen and senior medical school students(2016) MOTOKI, Marcelo Shigueo Yosikawa; CABAR, Fabio Roberto; FRANCISCO, Rossana Pulcineli VieiraOBJECTIVES: To compare the views of freshman students with senior students of the Faculty of Medicine-University of Sao Paulo concerning the respect for the mother's freedom of choice, the need to protect the unborn child, the proportionality between the mother's freedom of choice and the protection of the unborn child, and issues related to legal abortion. To determine whether the medical knowledge acquired throughout the academic years can influence the views of medical students on these issues. METHODS: First- and sixth-year students of the Faculty of Medicine - University of Sao Paulo answered a questionnaire; the inclusion criteria were as follows: a first- or sixth-year student of the medical school and a signature on the free informed consent form. To compare the proportions, a chi-square or Fisher's exact test was used. The significance level was set to 5%. RESULTS: Regarding the mother's freedom of choice, in the case when a pregnant woman undergoes a cesarean section by means of a court order despite her intention to not have a cesarean, 55.7% of the first-year students have answered that the mother's choice should be respected. Among the sixth-year students, only 28.9% believe that the mother's intention should be considered (p < 0.0001). With reference to the mother's choice in connection with antiretroviral medication, 38.1% of the first-year students agreed that the mother's intention should be respected, whereas 33% of sixth-year students believed that the mother's intention should be respected (p=0.453). CONCLUSION: There was a tendency to consider the unborn child's rights over the mother's choice as students spent more time in medical school.
