- First Trimester Examination of Fetal Anatomy: Clinical Practice Guideline by the World Association of Perinatal Medicine (WAPM) and the Perinatal Medicine Foundation (PMF)Publication . Volpe, N; Sen, C; Turan, S; Sepulveda, W; Khalil, A; Rolnik, D; De Robertis, V; Volpe, P; Gil, M; Chaveeva, P; Dagklis, T; Pooh, R; Kosinski, P; Cruz, J; Huertas, E; D’ Antonio, F; Rodriguez Calvo, J; Daneva Markova, AThis recommendation document follows the mission of the World Association of Perinatal Medicine in collaboration with the Perinatal Medicine Foundation. We aim to bring together groups and individuals throughout the world for precise standardization to implement the ultrasound evaluation of the fetus in the first trimester of pregnancy and improve the early detection of anomalies and the clinical management of the pregnancy. The aim is to present a document that includes statements and recommendations on the standard evaluation of the fetal anatomy in the first trimester, based on quality evidence in the peer-reviewed literature as well as the experience of perinatal experts around the world.
- Magnetic Resonance Imaging Target Fusion Biopsy vs. Transrectal Ultrasound-Guided Biopsy - A Comparative Study of ISUP Score Upgrading Risk in the Final Radical Prostatectomy SpecimenPublication . Guimarães, T; Gil, M; Medeiros, M; Andrade, V; Guerra, J; Pinheiro, H; Fernandes, F; Pina, J; Lopes Dias, J; Campos Pinheiro, LObjectives: The aim of this study was to com-pare the risk of International Society of Urological Pathology (ISUP) score upgrading between magnetic resonance imaging targeted fusion biopsy (MRI-TB) and tran-srectal ultrasound-guided biopsy (TRUS-B) in the final radical prostatectomy (RP) specimen pathological report. Materials and methods: This retrospective single center study included 51 patients with prostate cancer (PCa) diagnosed with MRI-TB and 83 patients diagnosed with TRUS-B between October/2019 and July/2021. We compared the rates of ISUP score upgrading between both groups after robotic-assisted radi-cal prostatectomy (RARP) and the specific transition of each ISUP score based on biopsy modality. The rate of ISUP score concordance and downgrading were also assessed. To define the intra and interobserver concordance for each ISUP score in biopsy and RP specimen for each biopsy modality, the Cohen's Kappa coefficient was calculated. ISUP scores and biopsy modal-ity were selected for multivariate analysis and a logistic regres-sion model was built to provide independent risk factors of ISUP score upgrading. Results: The difference of the rate of upgrading between MRI-TB group and TRUS-B group was statistically significant (p = 0.007) with 42.2% of patients of TRUS-B group experiencing an upgrade in their ISUP score while only 19.6% in MRI-TB group. Concordance and downgrading rates did not statistically differ between the two groups. Strength of concordance using Cohen's Kappa coefficient was fair in both groups but higher in MRI-TB group (TRUS-B group k = 0.230; p < 0.001; concordance: 47%vs. MRI/TB group k = 0.438; p < 0.001; concordance: 62.7%). Biopsy modality and ISUP 1 on biopsy were independent predic-tors of ISUP upgrading after RP. Conclusions: MRI-TB is highly accurate with lower risk of PCa upgrading after RP than TRUS-B. Patients with ISUP 1 on biopsy have greater susceptibility to upgrading their ISUP score.
- Risk of Fetal Loss After Chorionic Villus Sampling in Twin Pregnancy Derived from Propensity Score Matching AnalysisPublication . Gil, M; Rodríguez‐Fernández, M; Elger, T; Akolekar, R; Syngelaki, A; De Paco Matallana, C; Molina, F; Gallardo Arocena, M; Chaveeva, P; Persico, N; Accurti, V; Kagan, K; Prodan, N; Cruz, J; Nicolaides, KObjective: To estimate the risk of fetal loss associated with chorionic villus sampling (CVS) in twin pregnancy, using propensity score analysis. Methods: This was a multicenter cohort study of women with twin pregnancy undergoing ultrasound examination at 11-13 weeks' gestation, performed in eight fetal medicine units in which the leadership were trained at the Harris Birthright Research Centre for Fetal Medicine in London, UK, and in which the protocols for screening, invasive testing and pregnancy management are similar. The risk of death of at least one fetus was compared between pregnancies that had and those that did not have CVS, after propensity score matching (1:1 ratio). This procedure created two comparable groups by balancing the maternal and pregnancy characteristics that lead to CVS being performed, similar to how randomization operates in a randomized clinical trial. Results: The study population of 8581 twin pregnancies included 445 that had CVS. Death of one or two fetuses at any stage during pregnancy occurred in 11.5% (51/445) of pregnancies in the CVS group and in 6.3% (515/8136) in the non-CVS group (P < 0.001). The propensity score algorithm matched 258 cases that had CVS with 258 non-CVS cases; there was at least one fetal loss in 29 (11.2%) cases in the CVS group and in 35 (13.6%) cases in the matched non-CVS group (odds ratio (OR), 0.81; 95% CI, 0.48-1.35; P = 0.415). However, there was a significant interaction between the risk of fetal loss after CVS and the background risk of fetal loss; when the background risk was higher, the risk of fetal loss after CVS decreased (OR, 0.46; 95% CI, 0.23-0.90), while, in pregnancies with a lower background risk of fetal loss, the risk of fetal loss after CVS increased (OR, 2.45; 95% CI, 0.95-7.13). The effects were statistically significantly different (P-value of the interaction = 0.005). For a pregnancy in which the background risk of fetal loss was about 6% (the same as in our non-CVS population), there was no change in the risk of fetal loss after CVS, but, when the background risk was more than 6%, the posterior risk was paradoxically reduced, and when the background risk was less than 6%, the posterior risk increased exponentially; for example, if the background risk of fetal loss was 2.0%, the relative risk was 2.8 and the posterior risk was 5.6%. Conclusion: In twin pregnancy, after accounting for the risk factors that lead to both CVS and spontaneous fetal loss and confining the analysis to pregnancies at lower prior risk, CVS seems to increase the risk of fetal loss by about 3.5% above the patient's background risk. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.
- The Impact of Multidisciplinary Team Conferences in Urologic Cancer in a Tertiary HospitalPublication . Gil, M; Guerra, J; Andrade, V; Medeiros, M; Guimarães, T; Bernardino, R; Falcão, G; Calais da Silva, F; Campos Pinheiro, LPurpose: Multidisciplinary team (MDT) conferences are currently the standard of care in cancer patients' management. Despite evidence supporting benefits to the majority of malignancies, a paucity of data exists examining the impact in urinary and male genital cancers. This study aims to evaluate the impact of MDT conferences in urologic cancer practice. Methods: Clinical plans discussed in urologic MDT conferences in Centro Hospitalar Universitário de Lisboa Central between January 2019 and December 2019 were retrospectively analysed. Clinical plans were categorized as accepted, changed, rejected (cases that had to be re-presented to the MDT because of insufficient staging or administrative issues) or no plan. MDT conferences' impact was assessed according to type of consultation, referral medical specialty and primary tumour type. Results: 710 clinical plans were discussed at the MDT conferences. 61.8% were accepted, 10.6% were changed, 16.5% were rejected and 11.1% of cases referred to MDT discussion had no defined clinical plan. First consultations had a higher rate of accepted clinical plans (63.4%) versus subsequent consultations (56.4%). Referrals by the urology specialty had the highest rate of acceptances (64.3%). On the stratification by primary tumour site, testicular cancer had the highest acceptance rate (70.3%), whereas bladder cancer had the lowest (47.8%). Conclusions: MDT conferences had an important impact in the management of 38.2% of cases. Therefore, all patients with urologic malignancies should be referred to MDT review to ensure optimal clinical care.
