- Cervical Ripening with Foley Catheter: A Tertiary Center ExperiencePublication . Marujo, AT; Rosado, V; Correia, L; Machado, AI; Campos, AOverview and Aims: In the presence of an unfavorable cervix, pre-induction cervical ripening is an important part of the labour induction process. Both mechanical and pharmacological methods are available for this purpose, with Foley catheter being the most commonly used mechanical method. We intend to describe the efficacy of Foley catheter for cervical ripening and to describe maternal and neonatal outcomes. Furthermore, we analyze the same results in high risk subgroups. Study Design: Retrospective observational study Population: 44 women with a singleton pregnancy, live fetus, cephalic presentation, intact membranes, with medical indication for labour induction and Bishop score ≤6. Methods: Medical records were reviewed and analyzed. Foley catheter was introduced until expulsion or for a maximum of 24 hours. Cervical ripening was considered effective when Bishop score after catheter was ≥8. Maternal outcomes considered were tachysystole, chorioamnionitis, post-partum bleeding and uterine rupture. Neonatal outcomes assessed were Apgar score, need for hospitalization in neonatal care unit and days of hospitalization. In the subgroup analysis, we divided the risk population in two subgroups: Group 1- Fetal growth restriction and/or oligohydramnios; Group 2- Previous caesarean section. Results: 72.7% of the labour inductions were indicated by maternal or fetal disease. The efficacy of cervical ripening was 65.9% and vaginal delivery rate was 63.6%. Regarding maternal and neonatal outcomes, there were only two cases (4.5%) of clinical chorioamnionitis. In subgroup analysis, the efficacy of cervical ripening and vaginal delivery rates were, respectively, 60.9% and 69.6% in Group 1 and 72.2% and 50% in Group 2.There was one case of chorioamnionitis in each subgroup. Conclusions: Foley catheter is an effective and safe method for cervical ripening. Due to its low association with adverse outcomes, it appears to be a good alternative for high-risk populations.
- Uma Complicação Grave da Embolização das Artérias UterinasPublication . Correia, L; Simões, TUterine artery embolisation has been used as a therapeutic alternative for symptomatic uterine myomas. It is considered a safe and effective procedure, with very few cases published involving complications. The authors present a case of a 35-year-old nulliparous woman with an intramural myoma with 161x143x85mm, submitted to an uterine artery embolisation complicated by uterine necrosis. A hysterectomy was performed. This casereport reinforces the idea that artery embolization is not a riskfree procedure and serious complications may occur. Therefore, patients should be carefully selected.
- Composite Outcomes in Observational Studies of Ulcerative Colitis: a Systematic Review and Meta‐AnalysisPublication . Magro, F; Alves, C; Santiago, M; Ministro, P; Lago, P; Correia, L; Gonçalves, R; Carvalho, D; Portela, F; Dias, C; Dignass, A; Danese, S; Peyrin‐Biroulet, L; Estevinho, MM; Moreira, PBackground: Ulcerative colitis (UC) has been the focus of numerous observational studies over the years and a common strategy employed in their design is the use of composite and aggregate outcomes. Objective: This systematic review and meta-analysis aims to identify composite and aggregate outcomes of observational studies in UC and to evaluate how the number and type of variables included and the length of follow-up affect the frequency of patients that achieve these outcomes. Methods: A systematic literature search was carried out using MEDLINE [via PubMed], Scopus, and Web of Science online databases. Observational studies that included UC patients and reported composite or aggregate outcomes were identified. A set of variables considered to be representative of progressive or disabling UC was defined, the proportion of patients attaining the outcomes was determined and a random-effects meta-analysis was performed by dividing the identified studies into subgroups according to different criteria of interest. Results: A total of 10,264 records were identified in the systematic search, of which 33 were retained for qualitative analysis and 20 were included in the meta-analysis. The mean frequency for composite outcomes was 0.363 [95% confidence interval (CI) 0.323-0.403]. The frequency of composite outcome for the subgroup of studies that included the variable "Biologics" was significantly higher than for those in which this variable was not reported [0.410; 95% CI 0.364-0.457 versus 0.298; 95% CI 0.232-0.364; p = 0.006]. Composite outcomes were also more frequent as the follow-up duration increased. Conclusion: The frequency of composite outcomes in observational studies of UC is dependent on the specific identity of the variables being reported. Moreover, longer follow-up periods are associated with higher frequencies of composite outcomes. The evidence provided here is useful for the design of future observational studies of UC that aim to maximize the frequency of patients that achieve composite outcomes.
- Contraceptive Choices Pre and Post Pregnancy in AdolescencePublication . Correia, L; Martins, I; Oliveira, N; Antunes, I; Palma, F; Alves, MJSTUDY OBJECTIVE: The main aim of this study is to evaluate the impact of adolescent pregnancy in the future contraceptive choices. A secondary aim is to verify whether these choices differ from those made after an abortion. DESIGN: Retrospective study. SETTING:Adolescent Unit of a tertiary care center. PARTICIPANTS:212 pregnant teenagers. INTERVENTIONS: Medical records review. MAIN OUTCOME MEASURES:Intended pregnancy rate and contraceptive methods used before and after pregnancy. For contraceptive choices after pregnancy we considered: Group 1 - teenagers who continued their pregnancy to delivery (n = 106) and Group 2 - the same number of adolescents who chose to terminate their pregnancy. RESULTS: The intended pregnancy rate was 14.2%. Prior to a pregnancy continued to delivery, the most widely used contraceptive method was the male condom (50.9%), followed by oral combined contraceptives (28.3%); 18.9% of adolescents were not using any contraceptive method. After pregnancy, contraceptive implant was chosen by 70.8% of subjects (P < .001) and the oral combined contraceptives remained the second most frequent option (17.9%, P = .058). Comparing these results with Group 2, we found that the outcome of the pregnancy was the main factor in the choices that were made. Thus, after a pregnancy continued to delivery, adolescents prefer the use of LARC [78.4% vs 40.5%, OR: 5,958 - 95% (2.914-12.181), P < .001)], especially contraceptive implants [70.8% vs 38.7%, OR: 4.371 - 95% (2.224-8.591), P < .001], to oral combined contraceptives [17.9% vs 57.5%, OR: 0.118 - 95% CI (0.054-0.258), P < .001]. CONCLUSION:Adolescent pregnancy and its outcome constitute a factor of change in future contraceptive choice.
- Cross-Protection to New Drifted Influenza A(H3) Viruses and Prevalence of Protective Antibodies to Seasonal Influenza, During 2014 in PortugalPublication . Guiomar, R; Pereira da Silva, S; Conde, P; Cristóvão, P; Maia, AC; Pechirra, P; Rodrigues, AP; Nunes, B; Milho, L; Coelho, AP; Fernandes, A; Caseiro, P; Rodrigues, F; Correia, L; Pereira-Vaz, J; Almeida, S; Branquinho, P; Côrte-Real, R; Viseu, R; Peres, MJ; Sanches, R; Dantas, F; Freitas, L; Andrade, G; Maurílio, M; Caldeira, F; Cabral Veloso, R; Mota-Vieira, L; Soares, M; Couto, AR; Bruges-Armas, J; Mouro Pinto, R; Sobrinho Simões, J; Costa, MR; Guimarães, JT; Martins, L; Cunha, MINTRODUCTION: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portuguese population. MATERIALS AND METHODS: We developed a cross-sectional study based on a convenience sample of 626 sera collected during June 2014, covering all age groups, both gender and all administrative health regions of Portugal. Sera antibody titers for seasonal and new A(H3) drift influenza virus were evaluated by hemagglutination inhibition assay (HI). Seroprevalence to each seasonal influenza vaccine strain virus and to the new A(H3) drift circulating strain was estimated by age group, gender and region and compared with seasonal influenza-like illness (ILI) incidence rates before and after the study period. RESULTS: Our findings suggest that seroprevalences of influenza A(H3) (39.9%; 95% CI: 36.2-43.8) and A(H1)pdm09 (29.7%; 95% CI: 26.3-33.4) antibodies were higher than for influenza B, in line with high ILI incidence rates for A(H3) followed by A(H1)pdm09, during 2013/2014 season. Low pre-existing cross-protection against new A(H3) drift viruses were observed in A(H3) seropositive individuals (46%). Both against influenza A(H1)pdm09 and A(H3) seroprotection was highest in younger than 14-years old. Protective antibodies against influenza B were highest in those older than 65years old, especially for B/Yamagata lineage, 33.3% (95% CI: 25.7-41.9). Women showed a high seroprevalence to influenza, although without statistical significance, when compared to men. A significant decreasing trend in seroprotection from north to south regions of Portugal mainland was observed. CONCLUSIONS: Our results emphasize that low seroprotection increases the risk of influenza infection in the following winter season. Seroepidemiological studies can inform policy makers on the need for vaccination and additional preventive measures.
- Decisões Clínicas na Doença de CrohnPublication . Magro, F; Correia, L; Lago, P; Macedo, G; Peixe, P; Portela, F; Amil Dias, J; Barros, L; Belo, T; Caldeira, P; Cerqueira, R; Chagas, C; Correia, M; Ferreira, A; Freire, P; Gonçalves, AR; Gonçalves, R; Herculano, R; Lopes, S; Moura Santos, P; Machado, A; Morna, H; Pimentel, R; Ramos, J; Reis, J; Rodrigues, S; Rosa, I; Salgado, M; Vasconcelos, H; Vieira, AIA doença de Crohn é uma doença inflamatória crónica do trato gastrointestinal. O aumento da incidência e a heterogeneidade desta patologia, com diferentes apresentações e prognóstico leva a uma constante preocupação em desenvolver e melhorar a sua classificação e tratamentoObjectivos: Elaborar recomendações (com base no nível de evidência e grau de recomendação) para 5 questões consideradas como os desafios clínicos na abordagem terapêutica da doença de Crohn na actualidade. Métodos: A metodologia adoptada pelo grupo de trabalho DC2 (Desafios Clínicos na Doença de Crohn) baseou‑se na seleção de 5 questões‑problema, por votação; elaboração, por cada subgrupo, de recomendações e reflexões nacionais para cada questão‑problema; discussão e aprovação das respostas e reflexões de cada questão, em reunião de consenso. Conclusões: Foi possível efectuar conclusões alicerçadas na evidência para as questões colocadas, recomendando‑se: 1) são factores preditivos de mau prognóstico o aparecimento da doença de Crohn antes dos 40 anos, doença estenosante e doença anal; 2) poder‑se‑á ponderar suspender os biológicos em doentes com remissão endoscópica e com biomarcadores normais; 3) os doentes com marcadores bioquímicos de atividade (nomeadamente a PCR e a calprotectina) têm maior probabilidade de recidiva; 4) perante uma falência aos biológicos é essencial assegurar que o tratamento com o primeiro fármaco foi optimizado. No caso do infliximab, está demonstrado que quer a redução do intervalo das administrações ou o aumento da dose permitem recuperar a resposta na larga maioria dos doentes. Em relação ao adalimumab, os doentes deverão passar de terapêutica quinzenal para semanal 5) em situação de doença de Crohn com cirurgia intestinal, o recurso a terapêutica de redução da recorrência pós‑cirurgia, particularmente imunossupressores e biológicos está indicado.
- Esterilização Feminina: Estudo Comparativo entre Esterilização Histeroscópica e LaparoscópicaPublication . Correia, L; Queirós, A; Machado, AI; Delgado, E; Farelo, AOverview and Aims: Female sterilization is increasingly requested as a contraceptive method. Hysteroscopic sterilization by transcervical placing of Essure® micro-inserts in the initial portion of the tubes is a recent alternative to laparoscopic sterilization. The objective of this study is to evaluate the safety and effectiveness of hysteroscopic versus laparoscopic sterilization. Study Design: Retrospective cohort study. Population: A total of 98 women undergoing sterilization in an outpatient clinic between July 2005 and July 2009. Methods: Patients’ age, associated diseases, anesthesic risk, procedure time, discomfort, adverse events and success rate were evaluated. Results: Mean age at surgery was 37.8 years (19-49), and there were no statistically significant differences between the groups regarding this parameter. Women in the hysteroscopic group had a significant number of associated diseases (98% versus 47%), obesity (31% versus 6%), and anesthesic risk (ASA III- 31% versus 0%). The mean duration of the procedure was the same for both techniques (laparoscopy 28 minutes and hysteroscopy 26 minutes). All laparoscopic sterilizations were successfully completed. In the hysteroscopic group 4% failed to complete the technique. There were no cases of severe pain. Women in the hysteroscopy group reported pain less frequently (40% versus 57%, χ2 p<0.05). Long term success rate was similar in both groups (96% for hysteroscopy and 98% for laparoscopy). Conclusions: In spite of a higher incidence of associated diseases, obesity and anesthetic risks in the hysteroscopy group, there were no significant differences in the duration of the procedure, adverse events and success rate. The hysteroscopic approach can therefore be considered an alternative to laparoscopy, eliminating the need for incisional surgery and for general anaesthesia. If women with high surgical risk and several associated diseases can safely undergo this procedure, it could well become the preferred method for women who want a permanent and irreversible contraceptive method.
- Headache and HormonesPublication . Costa Ribeiro, V; Correia, L; Ferreira, A; Machado, AIAs hormonas desempenham um papel fundamental na modulação e exacerbação da cefaleia. A revisão da literatura apresentada descreve e diferencia os vários tipos de cefaleias hormonais, sendo igualmente abordados os mecanismos fisiopatológicos assim como as diversas opções terapêuticas. Dado o maior atingimento no sexo feminino e em idade reprodutiva várias questões se colocam no que concerne ao uso de contraceção hormonal. Por último será discutido o risco vascular na presença de enxaqueca o qual contraindica o uso de estrogénios em mulheres com aura.
- Implante Contraceptivo Não Palpável - Estratégias para a sua Localização e RemoçãoPublication . Isidro Amaral, P; Correia, L; Silveira Reis, I; Machado, AIOverview and Aims: The contraceptive implant is frequently used to provide contraceptive protection over three years. The implant is inserted into the subcutaneous tissue of the upper arm, and should be palpable and easily removed. We evaluated the best imaging strategy for non-palpable implant (Implanon®) localization and removal. Study Design: Retrospective study. Population: A total of 11 women referred to a tertiary care hospital, between October 2009 and January 2012, for localization and removal of their non-palpable implants. Methods: Different localization methods (ultrasound and magnetic resonance imaging) were evaluated for non-palpable rod. Results: Seven of the nonpalpable implants were inserted in a health care center, three in a district hospital and one in a private clinic. In three women, the reasons for requesting removal were the end of the implant validity, two wanted to become pregnant, two had weight gain, one had weight loss, one referred irregular bleeding, one had two implants and one did a hysterectomy. In 81.8% (9) of the women, the implants were identified and localized by ultrasound, and successfully removed. In two patients the implant was not found and therefore not removed. Conclusions: In our study, high resolution ultrasound proved to be a sensitive method in implants localization, being the primary choice for determining the location of nonpalpable implants.
- Levonorgestrel Intrauterine Device Effectiveness in Heavy Menstrual Bleeding Treatment in Obese WomenPublication . Oliveira, N; Rosado, V; Correia, L; Machado, AI; Marques, CObjective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.
