Abstract Objective To describe the evolution of maternal mortality right after the establish- ment of maternal death committees in the region of the city of Ribeirão Preto, state of São Paulo, Brazil. Methods The present study describes the spatial and temporal distribution of maternal mortality frequencies and rates, using data from the state of São Paulo, the municipality of Ribeirão Preto, and its Regional Health Department (DRS-XIII) from 1998 to 2017. The present ecological study considered the maternal mortality and live birth frequencies made available by the Computer Science Department of the Brazilian Unified Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS, in the Portuguese acronym)/Ministry of Health, which were grouped by year and political-administrative division (the state of São Paulo, the DRS-XIII, and the city of Ribeirão Preto).

of 48.0 in 2008–2009, and 54.1 for every 100 thousand live births in 2016–2017. Several times before 2015, the city of Ribeirão Preto and the DRS-XIII reached the Millennium Goals. Recently, however, the MMR increased, which can be explained by the improvement in the surveillance of maternal mortality. Conclusion The present study describes a sharp decline in maternal death in the region of Ribeirão Preto by the end of 2012–2013, and a subsequent and distressing increase in recent years that needs to be fully faced.

Resumo Objetivo Descrever a evolução da mortalidade materna após a instituição dos comitês de morte materna na região de Ribeirão Preto. Métodos Este estudo descreveu a distribuição espacial e temporal das frequências e da razão de mortalidade materna, utilizando dados do estado de São Paulo, do Departamento Regional de Saúde de Ribeirão Preto (DRS-XIII), e do município de Ribeirão Preto, no período de 1998 a 2017. O estudo ecológico considerou frequências de mortes maternas e de nascidos vivos disponibilizadas pelo Departamento de Informática do Sistema Único de Saúde (DATASUS)/Ministério da Saúde, que foram agrupadas por ano e pela referida divisão político-administrativa. A taxa de mortalidade materna (TMM) foi calculada e apresentada por medidas descritivas, gráficos e cartogramas. Resultados O total observado para o município de Ribeirão Preto foi uma TMM de 39,1; para o DRS-XIII, TMM de 40,4; e, para o estado de São Paulo, uma TMM de 43,8 por 100 mil habitantes.

Abstract Objective To describe the obstetric outcomes of patients with multiple sclerosis (MS) and the impact of pregnancy and the postpartum period on the progression of the disease. Methods A case series study performed between December 2019 and February 2020, reporting pregnancies occurred between 1996 and 2019. The subjects included were women with MS undergoing follow-up at an MS referral center in Northeastern Brazil, and who had at least one pregnancy after the onset of MS symptoms, or who had their first relapse in the first year after delivery. Results In total, 26 women and 38 pregnancies were analyzed – 32 of them resulted in delivery, and the remaining 6, in miscarriages. There was a significant increase in the prevalence of relapse during the postpartum period when compared with the gestational period.

Métodos Uma série de casos realizada entre dezembro de 2019 e fevereiro de 2020, que retrata gestações ocorridas entre 1996 e 2019. As pacientes incluídas neste estudo foram mulheres com EM, que realizam acompanhamento em um centro de referência em EM no Nordeste do Brasil, e que tiveram ao menos uma gestação após o início dos sintomas da EM, ou tiveram o primeiro surto da doença no ano posterior ao parto. Resultados No total, 26 mulheres e 38 gestações foram avaliadas – dentre as quais, 32 resultaram em partos, e 6, em abortamentos. Houve um aumento significativo na prevalência de surtos durante o pós-parto quando comparado com o período gestacional. Em 16 (42,1%) das gravidezes, houve exposição a terapias modificadoras da doença (TMDs) – 14 (36,8%) a β-interferona, e 2 (5,3%) a fingolimode.

Abstract Objective To evaluate the acceptability of postplacental placement of intrauterine devices (PPIUD), reasons for refusal and suggested policies to increase its use. Methods Cross-sectional study conducted at the Women Hospital of the Universi- dade de Campinas, Campinas, SP, Brazil. Postplacental placement of intrauterine devices was offered to women admitted in labor who did not present infections, uterine malformation, twin pregnancy, preterm birth, and were at least 18 years old. In case of refusal, the parturient was asked to give their reasons and the answers were classified as misinformation about contraception or other reasons. The following were considered misinformation: fear of pain, bleeding, contraception failure and future infertility. Bivariate analysis was performed. Results Amongst 241 invited women, the refusal rate was of 41.9%. Misinformation corresponded to 50.5% of all refusals, and the reasons were: fear of pain (39.9%); fear of contraception failure (4.9%); fear of bleeding (3.9%); fear of future infertility (1.9%); other reasons for refusal were 49.5%. Parturients aged between 18 and 27 years old refused the PPIUD more frequently due to misinformation (67.4%), and older partu- rients (between 28 and 43 years old) refused frequently due to other reasons (63.6%) (p ¼ 0.002). The mean age of those who declined the PPIUD due to misinformation was 27.3 6.4 years old, while those who declined for other reasons had a mean age of 29.9 5.9 years old (p ¼ 0.017). Keywords Conclusion The refusal of the PPIUD was high, especially amongst young women and ► postpartum due to misinformation. It is necessary to develop educative measures during antenatal ► contraception care to counsel women about contraception, reproductive health and consequences of ► intrauterine device unintended pregnancy. ► health education

Resumo Objetivo Avaliar a taxa de aceitação do dispositivo intrauterino pós-placentário (DIUPP); os motivos de recusa e propor medidas que aumentem sua aceitação. Métodos Estudo de corte transversal realizado no Hospital da Mulher da Universidade Estadual de Campinas, Campinas, SP, Brasil. O DIUPP foi oferecido a mulheres admitidas em trabalho de parto que não apresentavam: infecções, malformação uterina, gravidez gemelar,partoprematuroecomidademínimade18anos.Emcasoderecusa, perguntou-se o motivo, e as respostas foram agrupadas em informações equivocadas sobre contracepção ou outros motivos. Considerou-se informação equivocada: medo de dor, sangramentos, falha da contracepção e prejuízo da fertilidade. Análises bivariadas foram realizadas. Resultados Entre 241 mulheres, a taxa de recusa foi de 41,9%. A desinformação correspondeu a 50,5% de todos os motivos de recusa, que foram: medo da dor (39,9%); medo da falha da contracepção (4,9%); medo de sangramento (3,9%), medo de o dispositivo intrauterino (DIU) prejudicar a fertilidade (1,9%). Outros motivos de recusa atingem 49,5%. Parturientes com idade entre 18 e 27 anos recusaram o PPIUD com mais frequência devido a desinformação (67,4%), e as mais velhas (com idade entre 28 e 43 anos) recusaram com frequência devido a outros motivos (63,6%) (p ¼ 0,002). Houve diferença entre a idade média de quem recusou o PPIUD por desinformação (27,3 6,4 anos) em comparação com outras razões (29,9 5,9 anos), (p ¼ 0,017).

Abstract Objective The objective of the present study was to analyze the reasons that led to hormone therapies (HTs) regimen changes in women with breast cancer. Methods This was a retrospective cross-sectional study from a single-institution Brazilian cancer center with patient records diagnosed with breast cancer between January 2012 and January 2017. Keywords Results From 1,555 women who were in treatment with HT, 213 (13.7%) women had ► breast cancer HT switched, either tamoxifen to anastrozole or vice-versa. Most women included in ► tamoxifen the present study who switched HT were > 50 years old, postmenopausal, Caucasian, ► hormone therapy and had at least one comorbidity. From the group with therapy change, ‘disease ► aromatase inhibitor progression’ was reason of change in 124 (58.2%) cases, and in 65 (30.5%) patients, ► anastrozole ‘presence of side effects’ was the reason. From those women who suffered with side effects, 24 (36.9%) had comorbidities. Conclusion The present study demonstrated a low rate of HT switch of tamoxifen to anastrozole. Among the reasons for changing therapy, the most common was disease progression, which includes cancer recurrence, metastasis or increased tumor. Side effects were second; furthermore, age and comorbidities are risk factors for side effects.

Resultados De 1.555 mulheres em tratamento com HT, 213 (13,7%) mulheres tiveram HT alterado, tamoxifeno para anastrozol ou vice-versa. A maioria das mulheres incluídas no presente estudo que tiveram mudança de HT tinha > 50 anos, estava na pós-menopausa, era caucasiana e tinha pelo menos uma comorbidade. Os principais motivos de troca de HT foram devido a ’progressão da doença’, ocorrendo em 124 Palavras-chave (58,2%) casos e a ’presença de efeitos colaterais’ (n ¼ 65; 30,5%). Das mulheres que ► câncer de mama sofreram efeitos colaterais, 24 (36,9%) apresentaram comorbidades. ► tamoxifeno Conclusão O presente estudo demonstrou uma baixa taxa na alteração de tamoxi- ► terapia hormonal feno para anastrozol. Entre as razões mais comuns para alterar a HT estava a progressão ► inibidor da da doença, que inclui recorrência do câncer, metástase ou aumento do tumor. Os aromatase efeitos colaterais foram a segunda causa e, além disso, a idade e as comorbidades ► anastrozol foram fatores de risco para efeitos colaterais.

Abstract Objective To compare hand-held breast ultrasound (HHBUS) and automated breast ultrasound (ABUS) as screening tool for cancer. Methods A cross-sectional study in patients with mammographically dense breasts was conducted, and both HHBUS and ABUS were performed. Hand-held breast ultrasound was acquired by radiologists and ABUS by mammography technicians and analyzed by breast radiologists. We evaluated the Breast Imaging Reporting and Data System (BI-RADS) classification of the exam and of the lesion, as well as the amount of time required to perform and read each exam. The statistical analysis employed was measures of central tendency and dispersion, frequencies, Student t test, and a univariate logistic regression, through the odds ratio and its respective 95% confidence interval, and with p < 0.05 considered of statistical significance. Results A total of 440 patients were evaluated. Regarding lesions, HHBUS detected 15 (7.7%) BI-RADS 2, 175 (89.3%) BI-RADS 3, and 6 (3%) BI-RADS 4, with 3 being confirmed by biopsy as Keywords invasive ductal carcinomas (IDCs), and 3 false-positives.

Abstract Objective Covid-19 became a pandemic, and researchers have not been able to establish a treatment algorithm. The pregnant population is also another concern for health care professionals. There are physiological changes related to pregnancy that result in different laboratory levels, radiological findings and disease progression. The goal of the present article is to determine whether the laboratory results and radiological findings were different in non-pregnant women (NPWs) of reproductive age and pregnant women (PWs) diagnosed with the Covid-19 infection. Methods Out of 34 patients, 15 (44.11%) PWs and 19 (55.8%) NPWs were included in the study. Age, comorbidities, complaints, vitals, respiratory rates, computed tomog- raphy (CT) findings and stages, as well as laboratory parameters, were recorded from the hospital database. Results The mean age of the PWs was of 27.6 0.99 years, and that of the NPWs was of 37.63 2.00; when age was compared between the groups, a statistically significant difference (p ¼ 0.001) was found. The mean systolic blood pressure of the PWs was of 116.53 11.35, and that of the NPWs was of 125.53 13.00, and their difference was statistically significant (p ¼ 0.05). The difference in the minimum respiratory rates of the patients was also statistically significant (p ¼ 0.05). The platelet levels observed among the PWs with Covid-19 were lower than those of the NPWs (185.40 39.09 109/mcL and 232.00 71.04 109/mcL respectively; p ¼ 0.05). The mean D-dimer value of the PWs was lower in comparison to that of the NPWs Keywords (p < 0.05). ► covid-19 Conclusion The laboratory findings and imaging studies may differ between pregnant ► pregnancy and non-pregnant populations. It is important to properly interpret these studies. ► laboratory Future studies with a higher number of patients are required to confirm these ► imaging studies preliminary data.

Abstract Objective The evaluation of the available evidence on vertical transmission by severe acute respiratory syndrome coronavirus 2 (SARS-CoV)-2. Data Sources An electronic search was performed on June 13, 2020 on the Embase, PubMed and Scopus databases using the following search terms: (Coronavirus OR COVID-19 OR COVID19 OR SARS-CoV-2 OR SARS-CoV2 OR SARSCoV2)AND(vertical OR pregnancy OR fetal). Selection of Studies The electronic search resulted in a total of 2,073 records. Titles and abstracts were reviewed by two authors (WPM, IDESB), who checked for duplicates using the pre-established criteria for screening (studies published in English without limitation regarding the date or the status of the publication). Data Collection Data extraction was performed in a standardized way, and the final eligibility was assessed by reading the full text of the articles. We retrieved data regardingthe deliveryof the potential cases of verticaltransmission, as wellas the main findings and conclusions of systematic reviews. Data Synthesis The 2,073 records were reviewed; 1,000 duplicates and 896 clearly not eligible records were excluded. We evaluated the full text of 177 records, and identified only 9 suspected cases of possible vertical transmission. The only case with Keywords sufficient evidence of vertical transmission was reported in France. ► vertical transmission Conclusion The risk of vertical transmission by SARS-CoV-2 is probably very low. Despite ► SARS-CoV-2 several thousands of affected pregnant women, we have identified only one case that has ► COVID-19 fulfilled sufficient criteria to be confirmed as a case of vertical transmission.

Twin A tested positive 72 hours after birth; however, identified cases were reported as case reports; therefore, she did not exhibit any symptoms of infection. Twin B tested there is a very high risk of selection bias. After defining the negative 72 hours after birth. The authors argue that ,because eighteen eligible articles, we identified only seven suspected the patient was intubated at the time of delivery, that would cases of possible vertical transmission: two cases in China, make droplet transmission unlikely. Moreover, they claim one in Iran, two in Italy, one in Peru, and one in France that, because the babies were delivered via cesarean section, (►Table 1). that would eliminate the possibility of fetal contact with – The first are three different reports7 9 on the same case maternal feces, which has been reported as a mode of report from China that present a methodology bias, since the transmission.

Box 1 Conclusions from systematic reviews, narrative reviews and large observational studies identified in the present review

Systematic reviews Di Mascio et al. (2020):17 “In mothers infected with coronavirus infections, including COVID-19, > 90% of whom also had pneumonia, PTB is the most common adverse pregnancy outcome. Miscarriage, preeclampsia, cesarean, and perinatal death (7- 11%) were also more common than in the general population. There have been no published cases of clinical evidence of vertical transmission.” Della Gatta et al. (2020):18 “The available data on COVID-19 illness in pregnant patients do not provide a clear conclusion into the clinical implications for mother and fetus. The outcomethus far described is favorable, but fetal and maternal risks should be underestimated. Although preterm delivery was mostly the consequence of elective interventions, a trend towards spontaneous prematurity is present. It is essential that future studies provide more detailed information on maternal and fetal conditions, as well as the rationale for obstetric interventions. Experience, thus far, is limited to patients that developed the disease in late gestation and were delivered shortly after the diagnosis. The fetal consequences of long-standing infections occurring in early gestation are unknown.” Zaigham and Andersson (2020):19 “Current evidence suggests the possibility of severe maternal morbidity requiring ICU admission and perinatal death with COVID-19 infection in pregnancy. Maternal-fetal transmission of the SARSCoV-2 virus was not detected in the majority of the reported cases, although one neonate had a positive qRT-PCR 36 hours after birth despite being isolated from the mother. Careful monitoring of pregnancies with COVID-19 and measures to prevent neonatal infection are warranted.” Abdollahpour and Khadivzadeh (2020):20 “No trustworthy evidence is available yet to support the possibility of vertical transmission of COVID-19 infection from the mother–baby. Mother-to-child transmission of respiratory viruses mostly happens via the birth canal and during breastfeeding or close contact among health care providers, family members. To our knowledge, no article has reconnoitered that reporting a newly vertically transmitted case.” Banaei et al. (2020):21 “There was some evidence about neonates COVID-19 in the included studies, but it is not clear whether the source of the infection in these neonates is from the mother or from the environment. In the majority of studies, there was no evidence of vertical transmission. In most studies, the neonates were separated from the mother after birth to reduce the chance of transmission, but there is also currently insufficient evidence regarding the mother/baby separation. If the mother is severely or critically ill, separation should be considered. The result of a review showed that in SARS vertical transmissions were not seen. Duran et al. (2020):22 “There is still no evidence supporting vertical transmission of COVID-19. Some newborns were positive for COVID-19 in spite of the reported use of preventive measures during and after delivery, but even in these cases there was no evidence supporting vertical transmission.” Elshafeey et al. (2020):23 “We extracted data regarding potential vertical transmission. In four neonates who had RT-PCR confirmed infection, samples from cord blood and amniotic fluid were negative. Based on the available data, we are uncertain of the mode of transmission, since there is no evidence that these four cases were the result of a vertical transmission.” Gordon et al. (2020):24 “Neonatal infection is uncommon, with only two previously reported cases likely to be of vertical transmission. The case we report is still RT-PCR-positive on day 28, and is asymptomatic.” Huntley et al. (2020):25 “Data from early in the pandemic is reassuring that there are low rates of maternal and neonatal mortality and vertical transmission with SARS-CoV-2.” Juan et al. (2020):26 “Despite the increasing number of published studies on COVID-19 in pregnancy, there are insufficient good- quality data to draw unbiased conclusions with regard to the severity of the disease or specific complications of COVID-19 in pregnant women, as well as vertical transmission, perinatal and neonatal complications.” Kasraeian et al. (2020):27 “Currently, no evidence of vertical transmission has been suggested at least in late pregnancy. No hazards have been detected for fetuses or neonates. Although pregnant women are at an immunosuppressive state due to the physiological changes during pregnancy, most patients suffered from mild or moderate COVID-19 pneumonia with no pregnancy loss, proposing a similar pattern of the clinical characteristics of COVID-19 pneumonia to that of other adult populations.” Ludvigsson (2020):28 “Newborn infants have developed symptomatic COVID-19, but evidence of vertical intrauterine transmission was scarce.” Muhidin et al. (2020):29 “No fetal infection through intrauterine vertical transmission was reported.” Smith et al. (2020)30: “It is unclear if this is evidence of vertical transmission or if it was contracted post-delivery due to delayed RT-PCR testing 36 hours from birth. The evidence for vertical transmission appears equivocal.” Walker et al. (2020):31 “To date, there have been 28 cases published where the possibility for vertical transmission to have occurred have been reported. To confirm definite vertical transmission, it has been proposed that detection of the virus by PCR in either umbilical cord blood, neonatal blood collected within the first 12 hours of birth, or amniotic fluid collected prior to rupture of membranes is needed. In no cases reported to date have these criteria been met although some report negative testing. A few cases deserve special mention: one case reports a positive nasopharyngeal swab in the neonate on the day of birth. The authors do not describe any procedure or care taken to clean the infant’s oropharynx / mouth/nares / face prior to procuring the swab and we speculate that the presence of the virus may be due to contamination by maternal stool. Of note, the virus was not detected on repeat swab and the infant remained well. The presence of IgG would be maternal, so again not diagnostic. The UKOSS study reports 12/24 cases of possible vertical transmission. Limited information is given for the 12 neonates but 6/12 infants tested positive for COVID-19 within 12 hours of birth. It is unclear what method of testing was used and if this was a nasopharyngeal swab without precautions to clean the infant prior to testing, may again be a result of

Systematic reviews contamination. In another case, a positive nasopharyngeal swab in the neonate on the day of birth occurred after careful separation of the baby and cleansing of the baby prior to taking the swab.” Yang and Liu (2020)32: “There is currently no direct evidence to support intrauterine vertical transmission of SARS-CoV-2. Additional RT-PCR tests on amniotic fluid, placenta, and cord blood are needed to ascertain the possibility of intrauterine vertical transmission. For pregnant women infected during their first and second trimesters, further studies focusing on long-term outcomes are needed.” Yang et al. (2020):33 “Currently, there is no direct evidence suggesting that COVID-19 in pregnancy could lead to fetal infection via intrauterine vertical transmission. Long-term outcomes and potential intrauterine vertical transmission need further analysis.”

Abstract Acute pancreatitis is a rare condition in pregnancy, associated with a high mortality rate. Hypertriglyceridemia represents its second most common cause. We present the case of a 38-year-old woman in the 24th week of gestation with a history of hyper- triglyceridemia and recurrent episodes of pancreatitis. She was admitted to our hospital with acute pancreatitis due to severe hypertriglyceridemia. She was stabilized and treated with fibrates. Despite her favorable clinical course, she developed a second episode of acute pancreatitis complicated by multi-organ dysfunction and pancreatic necrosis, requiring a necrosectomy. The pregnancy was ended by cesarean section, Keywords after which three plasmapheresis sessions were performed. She is currently asymp- ► familial tomatic with stable triglyceride levels.

Two theories explain the trimester of gestation5; the cause in the first trimester is why hypertriglyceridemia causes acute pancreatitis. One theory usually biliary, whereas, in the second and third trimesters, proposes that high levels of chylomicrons increase the viscosity the cause is hypertriglyceridemia. A relationship has been of plasma, inducing ischemia in the pancreatic capillaries, which reported between severity and etiology, considering that the in turn generates acidosis and activates trypsinogen.7,13,14 cause is biliary in 39% of mild cases and that 58% of moderate According to the other theory, the increase in triglyceride and 100% of severe cases are due to hypertriglyceridemia.5 metabolism leads to increased production of free fatty acids, Our patient experienced three episodes of pancreatitis dur- which causes cytotoxic damage to pancreatic acinar cells.8

The National Specialty Commission for Lower Genital Tract of the Brazilian Federation of Gynecology and Obstetrics Associations (FEBRASGO) endorses to this document. The content production is based on scientific studies on a thematic proposal and the findings presented contribute to clinical practice.

Key points: • Address the importance of organized screening for cervical cancer. • Indicate new technologies in screening. • Anogenital warts are caused by HPV, mainly 6 and 11. • The diagnosis of condyloma acuminata is clinical with several effective therapeutic options. • Low-grade squamous intraepithelial lesion (LSIL) and atypias of undetermined significance in squamous cells (ASC-US). • As the risk of histological high-grade squamous intraepithelial lesion (HSIL) in a patient with cytological LSIL is significant, the quality of the cytopathological examination is essential. • Cases of cytological HSIL should be systematically referred to colposcopy. • “See-and-treat” is a diagnostic and therapeutic procedure and must be performed according to rules estab- lished for non-pregnant women over 25 years of age. • “See-and-treat” should not be performed in adolescents given the future possibility of obstetric comorbidities.

Recommendations: • Screening should be organized based on population data records with wide coverage. • The HPV DNA test must be offered for screening. • The therapeutic method for warts should be changed if there is no significant improvement within four weeks of treatment. • Podophyllin, 5-fluorouracil and imiquimod should not be used during pregnancy. • Conservative therapy for HSIL is preferred in patients ≤ 25 years of age. • In patients ≥ 25 years of age, risk estimates such as immunosuppression, HPV DNA positive and previous al- tered cytology and/or biopsy results should be considered. • The cytopathology of HSIL should be referred to colposcopy, it is not acceptable to repeat the cytopathology exam. • The endocervical canal should be evaluated with cytological brushing or curettage when the squamocolumnar junction (SCJ) is not visible. • After treatment of HSIL, follow-up with cytology and colposcopy is recommended every six months for two years then, annual cytology until completing five years. If possible, perform HPV DNA test on high-risk patients after six months and annually for three years; if tests are negative, return to triennial screening for 25 years.
