Primary biliary cholangitis first demonstrated in pregnancy: a case report.

BACKGROUND: We present a case of primary biliary cholangitis diagnosed during pregnancy. Diagnosis of this entity in pregnancy is infrequent, and when everything seemed to point to a simple obstetric cholestasis, close attention to the details of the clinical history was required to raise suspicion of the true diagnosis. CASE PRESENTATION: We present a 37-year-old Portuguese Caucasian patient who complained of generalized pruritus and showed alteration in hepatic function tests with a cholestatic pattern. The first diagnostic hypothesis was intrahepatic cholestasis of pregnancy, and she began treatment with ursodeoxycholic acid, which resulted in slight improvement of cholestasis. Her pregnancy was also complicated with occlusive hemorrhagic placenta, and at 30 weeks she underwent emergency cesarean section due to heavy blood loss. However, careful observation of clinical and laboratory findings, postpartum evolution, and a multidisciplinary approach to the patient led to the probable diagnosis of primary biliary cholangitis. CONCLUSIONS: Physiological changes during pregnancy can mimic chronic liver disease that can only be revealed at this stage, having an impact not only on the pregnancy but on the entire future of the woman.

Kidney graft function before pregnancy as a predictor of graft, maternal and fetal outcomes in pregnant renal transplant recipients.

OBJECTIVES: Maternal and fetal complications can occur in pregnant kidney transplant recipients. Since these are high-risk pregnancies, they require a multidisciplinary follow-up to prematurely detect adverse events. Identifying factors that would affect fetal, maternal and graft outcomes is essential to further stratify the risk of pregnant kidney transplant recipients. METHODS: All pregnancies in kidney transplant recipients followed in a single center for 30 years were included. Data included previous transplant information and blood and urine tests performed before pregnancy. Impact of graft function on fetal, maternal and graft outcomes was evaluated. RESULTS: There were 41 pregnancies among 34 patients. Mean gestational age of 35 ± 3 weeks. Caesarean section was performed in 69.4% of patients. Five pregnancies were unsuccessful (12.2%). Four patients suffered an acute graft dysfunction (9.8%) and 12 (29.3%) had a serious maternal hypertensive disorder (preeclampsia, eclampsia or HELLP syndrome). Graft function before pregnancy showed significant correlation with adverse outcomes. CONCLUSIONS: A proteinuria >669 mg/g, serum creatinine >1.75 mg/dL and glomerular filtration rate <36.2 mL/min/1.73 m2 before pregnancy were correlated to graft dysfunction during pregnancy. Similar values of proteinuria were also associated with a risk of maternal hypertensive disorders and pregnancy failure. Therefore, in patients with proteinuria and graft dysfunction, follow-up should be stricter to quickly detect complications.

Ophiophagy in Brazilian birds: a contribution from a collaborative platform of citizen science

Citizen science is the interaction of the non-academic community in scientific studies, often extended to collaborative platforms. We analyzed 168 photographs shared in a Brazilian citizen science platform to understand the feeding interactions between birds and snakes in Brazil, comparing our findings to published data. We searched for patterns in bird taxa and behaviour correlated with ophiophagy, snake groups most vulnerable to predation, and biases resulting from citizen science data. Records were made mostly in south-eastern and southern Brazil. Both birds and snakes recorded are primarily diurnal, terrestrial, and use open habitats. Predators represent especially birds of prey, but nine other families were observed, and most of the identified snakes belong to Dipsadidae and Colubridae. Venomous snakes were observed, suggesting that birds must deploy strategies to avoid injuries. Finally, we added a new vertebrate item to the diet of the white-faced ibis (Plegadis chihi). Data biases of citizen science platforms, which in this work include differences in the number of records between different geographic regions and periods of day, must be considered. However, this kind of data can be a powerful tool for understanding life history patterns and natural history of birds and other animals.

Objetivo: Correlacionar poluição atmosférica com hospitalizações de idosos em Nova Iguaçu por doenças pulmonares entre 2007 a 2016. Metodologia: Estudo observacional, retrospectivo. O poluente analisado foi o Material Particulado (PM10). Os dados de qualidade do ar foram fornecidos pelo (INEA). Dados de hospitalização pelo (AIH). Foram selecionadas doenças do aparelho respiratório pelo CID X e subcapítulos J. A análise estatística foi realizada pelo SPSS IBM25 com dados expressos em média, desvio padrão, mediana e intervalo de confiança de 95%. Utilizou-se o teste t para amostras independentes, a diferença estatística foi dada pelo p<0,05. A relação entre poluição do ar e hospitalizações utilizou o coeficiente de correlação de Pearson. Resultados: As médias mensais de PM10 e hospitalizações foram, respectivamente, 74,7 mg/m3 (±16,2), (IC=63,8-87,1); 40,6 (±13,5) (IC= 37,5 ­ 43,5). Os homens representaram (52,4%), que totalizaram 2.239 internações em 10 anos, em que 2015 foi o ano com maior índice de hospitalizações (615). A doença mais incidente foi o J18 com média anual de 102,7. A pneumonia viral acometeu três vezes mais mulheres (p<0,042). A correlação de Pearson entre PM10 e hospitalizações (R=-0,230). Conclusão: O sexo mais acometido entre os idosos foi o masculino. Os agravos pulmonares de maior hospitalização foram as pneumonias, insuficiência respiratória e DPOC. Apesar da não conformidade dos níveis de PM10 em 10 anos houve redução de 60% das concentrações. Os meses entre maio e agosto demonstraram as maiores elevações de PM10 e hospitalizações. A correlação mensal entre hospitalizações de idosos e PM10 foi negativa e fraca.(AU)

Objective: Correlate air pollution with hospitalizations of elderly people in Nova Iguaçu (RJ) for pulmonary diseases between 2007 and 2016. Methodology: Observational, retrospective study. The pollutant analyzed was Particulate Material (PM10). Air quality data was provided by INEA. Hospitalization data was provided by AIH. Respiratory system diseases were selected by CID X and subchapters J. The statistical analysis was performed by SPSS IBM 25, with data expressed as mean, standard deviation, median and 95% confidence interval. The t test for independent samples was used, the statistical difference was given by p<0.05. The relationship between air pollution and hospitalizations used Pearson's correlation coefficient. Results: The monthly averages of PM10 and hospitalizations were 74.7 mg/m3 (± 16.2), respectively (CI = 63.8-87.1); 40.6 (± 13.5) (CI = 37.5 - 43.5). Men represented 52.4%, which totaled 2,239 hospitalizations in 10 years, 2015 was the year with the highest rate of hospitalizations (615). The most incident disease was J18 with an annual average of 102.7. Viral pneumonia affected three times as many women (p<0.042). Pearson's correlation between PM10 and hospitalizations (R = -0.230). Conclusion: The sex most affected among the elderly was male. The pulmonary diseases with the highest hospitalization were pneumonia, respiratory failure and COPD. Despite the non-compliance of PM10 levels in 10 years, there was a 60% reduction in concentrations. The months between May and August showed the highest increases in PM10 and hospitalizations. The monthly correlation between hospitalizations of the elderly and PM10 was negative and weak.(AU)

West Nile Virus in the State of Ceará, Northeast Brazil.

In June 2019, a horse with neurological disorder was diagnosed with West Nile virus (WNV) in Boa Viagem, a municipality in the state of Ceará, northeast Brazil. A multi-institutional task force coordinated by the Brazilian Ministry of Health was deployed to the area for case investigation. A total of 513 biological samples from 78 humans, 157 domestic animals and 278 free-ranging wild birds, as well as 853 adult mosquitoes of 22 species were tested for WNV by highly specific serological and/or molecular tests. No active circulation of WNV was detected in vertebrates or mosquitoes by molecular methods. Previous exposure to WNV was confirmed by seroconversion in domestic birds and by the detection of specific neutralizing antibodies in 44% (11/25) of equids, 20.9% (14/67) of domestic birds, 4.7% (13/278) of free-ranging wild birds, 2.6% (2/78) of humans, and 1.5% (1/65) of small ruminants. Results indicate that not only equines but also humans and different species of domestic animals and wild birds were locally exposed to WNV. The detection of neutralizing antibodies for WNV in free-ranging individuals of abundant passerine species suggests that birds commonly found in the region may have been involved as amplifying hosts in local transmission cycles of WNV.

Physician awareness regarding contraceptive counselling in women with chronic disease.

INTRODUCTION: Contraceptive counselling is essential in women with chronic disease, though it is frequently overlooked. We aimed to assess practices and awareness in contraceptive counselling in hospital physicians caring for reproductive age women with chronic disease. METHODS: A questionnaire was distributed in April 2017 to physicians from 16 medical specialties in a tertiary care hospital in Portugal. Statistical analysis performed using Microsoft Office Excel® and IBM SPSS-Statistics®. RESULTS: Two-hundred physicians participated in the survey: 59.5% were female, 55% under 35 years-old and 48.5% were residents. Only 26.5% practiced in surgical specialties. Two-thirds consistently inquired about the use of contraception. Most referred patients to Family Planning services or performed contraceptive counselling when pregnancy posed significant health risks (89.0%), when prescribing teratogenic medication (79.5%) or drugs with potential interaction with contraceptives (75.0%). Lack of training in contraception was the main reason for not referring patients to Family Planning services. While 83% considered counselling very important, only 5% had recently undergone training and 12.5% felt knowledgeable enough to perform it. Only 12.5% were aware of the institution's Family Planning resources. Female gender, non-surgical specialty, age over 35 years-old and over 10 years since specialisation were positively associated with awareness. CONCLUSION: Most physicians addressed contraceptive management in women with comorbidities, but adequate training is lacking. Our results highlight the importance of communication between health care providers to achieve an adequate and multidisciplinary approach to reproductive and general health goals.

Menstrual pattern and contraceptive choices of Portuguese athletes.

OBJECTIVES: Menstrual symptoms are commonly cited barriers to physical activity in women. Delay or avoidance of menstruation through hormonal contraceptives may mitigate those barriers. Our purpose is to identify the uterine bleeding patterns of Portuguese athletes, their contraceptive choices and the impact of contraceptive methods in sports performance. We aim also to compare the outcomes between users and non-users of contraception. METHODS: Observational, descriptive and comparative study based on a customised self-assessment online survey aimed at Portuguese athletes. Athletes had to be at least 16 years old and competing at a national, international or professional level. RESULTS: A total of 256 athletes from 18 modalities were eligible. The mean age was 29 years and the mean age of menarche was 12.8 years. Monthly bleeding pattern was prevailing and 50% presented dysmenorrhoea. More than 85% experience fluctuations in sports performance throughout the month. The majority (71.5%) used contraceptive methods. Only 16% believed that contraception decreased sports performance. Contraceptive users exhibit a lower mean body mass index, blood loss and percentage of dysmenorrhoea than the non-users. CONCLUSION: Most athletes had the perception that performance varies throughout the month. The majority of participants do not report amenorrhoea and have monthly menses. The use of contraceptive methods is reportedly high, benefit cycle control and apparently without any physical inconvenience.

[Pregnancy and Hemodialysis: About a Successful Twin Pregnancy]. / Gravidez e Hemodiálise: A Propósito de uma Gravidez Gemelar Bem Sucedida.

Pregnancy is a rare condition in women with chronic kidney disease on hemodialysis, but its incidence has increased in recent years. Despite being a high-risk condition for both mother and fetus, there has been an improvement in care due to the increased number of cases described and the experience gained in dialysis therapy. We report the case of a multiparous 32-years-old women with chronic hypertension and chronic kidney disease with 10 years of evolution and difficult control, with a diagnosis of dichorionic/diamniotic twin pregnancy, 4 months after beginning hemodialysis. Pregnancy was managed by a multidisciplinary team, hemodialysis sessions were clinically and hemodynamically well tolerated, with good blood pressure and analytical control, as well as adequate development of both fetuses. She went into labor at 34 weeks and 6 days, so a caesarean section was performed, with 2 boys born with adequate weight for gestational age.

A gravidez é uma situação rara em mulheres com doença renal crónica sob hemodiálise. Contudo, a sua incidência tem aumentado nos últimos anos. Apesar de ser uma situação de elevado risco materno e fetal, tem havido uma melhoria na assistência, devido ao aumento do número de casos descritos e da experiência adquirida na terapia dialítica. Relatamos o caso de uma multípara de 32 anos com hipertensão crónica e doença renal crónica com 10 anos de evolução e difícil controlo, com diagnóstico de gravidez gemelar bicoriónica/biamniótica, quatro meses após início da hemodiálise. A gestação foi vigiada por uma equipa multidisciplinar, as sessões de hemodiálise bem toleradas clínica e hemodinamicamente, com bom controlo tensional e analítico seriado, assim como adequado desenvolvimento de ambos os fetos. Foi submetida a cesariana às 34 semanas e seis dias por início de trabalho de parto, tendo nascido dois meninos com peso adequado para a idade gestacional.

Effect of the inclusion of static stretching in general warming up on muscle strength in Brazilian army military personnel

Abstract Aim: Several health professionals prescribe static stretching exercises (SS) as essential for those that practice physical exercises, for injury prevention and performance improvement, although there is still no consensus. There are few studies on the effects of SS use on warming up. Thus study aimed to compare the effects of the inclusion of SS in general warming up procedures on muscle strength in Brazilian army personnel. Methods: Thirty-two young military men were selected. They were subjected to anthropometric evaluation and performed knee extension and flexion in an isokinetic digital dynamometer, at a speed of 60°/s. Then, they were divided into two randomized and counterbalanced groups, Traditional Group (TG) and Experimental Group (EG). The TG performed the lower limbs warm-up protocol provided for military physical training (MPT) and immediately after, performed the isokinetic muscle strength test. The EG performed the same protocol, performing the SS in the hamstrings and quadriceps, before warming up. Results: An increase was found in the peak isokinetic torque in the knee extension of the EG (Pre: 209.80 ± 21.36 vs Post: 243.98 ± 30.35; p = 0.001) and flexion (Pre: 130.86 ± 18.63 vs Post: 142.41 ± 25.92; p = 0.006). In the TG, significant differences were found in the extension of the knee, but not in flexion (Pre: 209.14 ± 34.27 vs. Post: 239.38 ± 36.17; p = 0.001 and Pre: 129.23 ± 18.43 vs Post: 133.66 ± 13.20; p = 0.297, respectively). Conclusion: The inclusion of SS in general warming up did not harm and even improved muscle strength performance in knee extension and flexion in Brazilian Army military personnel.

Introdução: As pessoas estão envelhecendo cada vez mais no Brasil e no mundo. Estudos apontam que o processo de envelhecimento populacional é acompanhado com o aumento de ocorrência de morbidade e incapacidade. Diferentes condições podem ser apresentadas pelo envelhecimento, como: diminuição da capacidade funcional, diminuição da força e da massa muscular, entre outros. Objetivo: Investigar a redução da capacidade funcional, secundária a redução de força muscular de membros inferiores em idosos institucionalizados em duas instituições de longa permanência (ILPI) no município de Nova Iguaçu (RJ/Brasil). Métodos: Trata-se de um estudo transversal, exploratório de caráter quantitativo em duas IAPI em Nova Iguaçu/RJ/ no período do mês de julho e agosto de 2017, em que foram selecionados 60 idosos de ambos os sexos (34 homens e 26 mulheres), com faixa etária ≥ 60 anos. Os voluntários foram avaliados quanto a capacidade funcional e a força muscular. Para a capacidade funcional, foi utilizado a escala de Barthel. Para o teste de força, o presente estudo usou para forma de avaliação a escala de Medical Research Council (MRC). Resultados: Os resultados mostraram que 61,7% dos idosos são classificados como independentes pelo índice de Barthel. Na escala de MRC, 95% dos idosos apresentaram fraqueza muscular. Conclusão: Concluímos que a maior proporção de idosos institucionalizados foram considerados independentes, porém, apresentaram quadro de fraqueza muscular. (AU)

Introduction: People are aging more and more in Brazil and worldwide. Studies show that the process of population aging is accompanied by increased occurrence of morbidity and disability. Different conditions can be presented by aging, such as: decreased functional capacity, decreased strength and muscle mass, among others. Objective: To investigate the reduction of functional capacity, secondary to the reduction of muscular strength of lower limbs in elderly institutionalized in two institutions in the municipality of Nova Iguaçu/RJ Brazil. Methods: This is a quantitative exploratory study in two elderly institutions at Nova Iguaçu during the period of July and August 2017, with 60 elderly men and women (34 males and 26 females), age range ≥ 60 years. The volunteers were assessed for functional capacity and muscle strength. For functional capacity, the Barthel scale was used. For strength testing, the present study used the Medical Research Council (MRC) scale for evaluation. Results: The results of the present study showed that 61.7% of the elderly are classified as independent by the Barthel index. In the MRC scale, 95% of the elderly presented muscular weakness. Conclusion: We concluded that the most proportion of institutionalized elderly was considered independent but presented a picture of muscular weakness. (AU)

The role of innate immunity in spontaneous preterm labor: A systematic review.

BACKGROUND: Immunoinflammatory response by innate immunity components is a field with increasing interest in understanding the mechanisms behind preterm labor (PTL). OBJECTIVES: Systematic review of the role of innate immunity in spontaneous PTL. STUDY DESIGN: PubMed, Scopus, ClinicalTrials.gov and Web of Science were searched using pregnancy AND innate OR toll-like OR natural-killer OR dendritic AND delivery OR premature OR rupture of membranes. MAIN OUTCOME MEASURES: All article titles and abstracts were evaluated by two individuals, based in strict predefined inclusion criteria. For relevant studies, title, abstract, and full text were assessed to identify PTL and innate immunity studies, excluding multiple pregnancies, cervical insufficiency and indicated PTL. RESULTS: From 894 articles evaluated, 101 full texts articles were assessed independently. For this systematic review 44 studies were finally included. Toll-like receptors 2 and 4 mediated immune dysfunction and inflammation can result in PTL. Moreover, PTL is linked to high levels of CD14+ monocytes; neutrophils seem important in inflammation-associated PTL and in pathological preterm premature rupture of membranes. Besides, decidual natural-killer cells and premature activation of dendritic cells may also participate in the etiology of PTL. Finally, dysregulation of maternal complement might increase the risk of PTL, characterized by high levels of innate lymphoid cells 2 and 3. CONCLUSIONS: Further research is warranted to ascertain the precise role of innate immunity in PTL. Nonetheless, our results indicate that Toll-like receptors, monocytes, natural-killer cells, dendritic cells and complement have significant roles in PTL.

[Gestational Diabetes Mellitus: Is There an Advantage in Using the Current Diagnostic Criteria?] / Diabetes Gestacional: Serão os Atuais Critérios de Diagnóstico Mais Vantajosos?

INTRODUCTION: There is no international consensus regarding gestational diabetes mellitus diagnostic criteria. In Portugal, the Carpenter and Coustan criteria were replaced by an adaptation of the International Association of Diabetes and Pregnancy Study Groups criteria. Our aim was to compare the incidence and outcomes of pregnancies complicated by gestational diabetes mellitus according to the current and previous criteria. MATERIAL AND METHODS: Retrospective analysis of 1218 singleton pregnancies complicated with gestational diabetes mellitus, with surveillance/delivery between 2008-2015. Two groups were considered: identification according to the Directorate-General of Health criteria - International Association of Diabetes and Pregnancy Study Groups (group 1); identification through Carpenter and Coustan criteria (group 2). A comparative analysis was performed. RESULTS: The incidence of gestational diabetes mellitus doubled (9.4% vs 4.6%), and the number of consultations/year increased (~3000 vs ~2000). In Group 1, in comparison with group 2, there was a lower risk of macrosomia in newborns [RR 0.44 (IC (95%):0.26 - 0.76)] and a higher risk of small for gestational age infants [RR 1.99 (IC (95%):1.19 - 3.31)]; a 6 - fold and 4 fold higher risk in neonatal hypoglycemia [RR 6.30 (IC (95%): 3.39 - 11.71)] and hyperbilirubinemia [RR 3.89 (IC (95%): 2.25 - 6.72)] were also observed, respectively. There were no differences regarding other outcomes. DISCUSSION: Outcomes related to the decrease in macrosomia did now show any improvement, with even an increase in Small for Gestational Age and neonatal complications. Given the increased incidence of gestational diabetes mellitus, Directorate-General of Health - International Association of Diabetes and Pregnancy Study Groups criteria may be associated with greater healthcare-related costs due to more frequent consultations, with no apparent obstetrical/neonatal benefit. CONCLUSION: The Directorate-General of Health - International Association of Diabetes and Pregnancy Study Groups criteria were associated with a decrease in macrosomia, not accompanied by an improvement of obstetrical/perinatal outcomes. The benefit of using these criteria is open to debate.

Introdução: Não existe consenso internacional quanto aos critérios de diagnóstico da diabetes gestacional. Em Portugal, os critérios de Carpenter e Coustan foram substituídos por uma adaptação dos critérios da International Association of Diabetes and Pregnancy Study Groups. O objetivo deste estudo foi comparar a incidência e outcomes obstétricos/perinatais das grávidas com diabetes gestacional segundo os critérios atuais e prévios. Material e Métodos: Estudo retrospetivo de 1218 gestações únicas complicadas com diabetes gestacional cuja vigilância/parto ocorreu entre 2008-2015. Consideraram-se dois grupos: diagnóstico pelos critérios da Direção Geral da Saúde ­ International Association of Diabetes and Pregnancy Study Groups (grupo 1); diagnóstico segundo Carpenter e Coustan (grupo 2), tendo sido feita análise estatística comparativa. Resultados: A incidência da diabetes gestacional duplicou (9,4% vs 4,6%) e o número de consultas/ano aumentou consideravelmente (~ 3 000 vs ~ 2 000). No grupo 1 verificou-se um risco inferior de recém-nascidos macrossómicos em relação ao grupo 2 [RR 0,44 (IC (95%): 0,26 ­ 0,76)], e um risco mais elevado de recém-nascidos leves para a idade gestacional (LIG) [RR 1,99 (IC (95%):1,19 ­ 3,31)]; um risco cerca de seis e quatro vezes superior de hipoglicémia [RR 6,30 (IC (95%): 3,39 ­ 11,71)] e hiperbilirrubinémia [RR 3,89 (IC (95%): 2,25 ­ 6,72)] neonatais, respetivamente. Não houve diferenças em relação a outros outcomes. Discussão: A redução dos recém-nascidos macrossómicos não resultou em melhoria dos outcomes, havendo um aumento dos recém-nascidos leves para a idade gestacional bem como de complicações neonatais. Os critérios atuais poderão associar-se a maiores gastos em saúde, devido ao aumento considerável da incidência de diabetes gestacional e maior vigilância em consultas, sem benefícios obstétricos/perinatais. Conclusão: A aplicação dos critérios da Direção Geral da Saúde ­ International Association of Diabetes and Pregnancy Study Groups associou-se a redução da macrossomia, não acompanhada de uma melhoria dos outcomes. É discutível o benefício destes critérios em relação aos anteriormente preconizados.

Amniotic membrane extract differentially regulates human peripheral blood T cell subsets, monocyte subpopulations and myeloid dendritic cells.

The discovery of the immunoregulatory potential of human amniotic membrane (hAM) propelled several studies focusing on its application for the treatment of immunological disorders. However, there is little information regarding the effects of hAM on distinct activation and differentiation stages of immune cells. Here, we aim to investigate the effect of human amniotic membrane extract (hAME) on the pattern of cytokine production by T cells, monocytes and myeloid dendritic cells (mDCs). For this purpose, peripheral blood mononuclear cells (PBMCs) from eight healthy individuals were stimulated in vitro in the presence or absence of hAME. Mitogen-induced proliferation of PBMCs and cytokine production among the distinct T cell functional compartments, monocyte subpopulations and mDCs were evaluated. hAME displayed an anti-proliferative effect and decreased the frequency of T cells producing tumor necrosis factor (TNF)α, interferon (IFN)γ and interleukin (IL)-2, for all T cell functional compartments. The frequency of IL-17 and IL-9-producing T cells was also reduced. The inhibition of mRNA expression of granzyme B, perforin and NKG2D by CD8+ T cells and γδ T cells and the augment of FoxP3 and IL-10 in CD4+ T cells and IL-10 in regulatory T cells were also observed. Furthermore, hAME inhibited IFNγ-induced protein (IP)-10 expression by classical and non-classical monocytes, without hampering the production of TNFα and IL-6 by monocytes and mDCs. These results suggest that hAME exerts an anti-inflammatory effect on T cells, still at a different extent for distinct T cell functional compartments.

Acute Onset Neurological Disorders during Pregnancy: A Literature Review / Doenças neurológicas de início durante a gravidez: análise crítica da literatura

Abstract Objectives To characterize the most common peripheral and central neurological disorders during pregnancy. Methods Original research and review of the literature on neurological complications during pregnancy. We searched for keywords related to the topic on different databases. Results Pregnancy involves physiological changes that can trigger peripheral neurological and/or central nervous system pathologies, which can sometimes be associated with hypertensive disorders. A definitive diagnosis of neurological disorders can be made according to the trimester of pregnancy and the clinical findings. Carpal tunnel syndrome and peripheral facial palsy are common peripheral neurological disorders, more frequent in the second half of pregnancy. Central nervous disorders are more complex and a precise diagnosis must be made in order to improve perinatal outcomes, provide correct management and treatment and to prevent acute and long-term complications. Conclusions It is possible to achieve a precise diagnosis,management and treatment of neurological disorders during pregnancy, but these require a multidisciplinary approach, crucial to improve perinatal outcomes.

Resumo Objetivos Caracterizar as alterações neurológicas centrais e periféricas mais comuns durante a gravidez. Métodos Foi efetuada uma revisão da literatura acerca de complicações neurológicas durante a gravidez. Foram utilizadas diversas bases de dados usando palavras-chave relacionadas com o tema. Resultados A gravidez envolve alterações fisiológicas que podem desencadear alterações neurológicas periféricas e/ou do sistema nervoso central, por vezes associadas a distúrbios hipertensivos. Um diagnóstico definitivo pode ser feito tendo em conta o trimestre de gravidez e os achados clínicos encontrados. A síndrome do túnel carpal e a paralisia facial periférica são alterações neurológicas periféricas comuns que ocorrem mais frequentemente na segunda metade da gravidez. As alterações em termos do sistema nervoso central são mais complexas. Um diagnóstico preciso é fulcral, não só para melhorar os desfechos perinatais, mas também para efetuar uma vigilância e tratamento adequados e para prevenir complicações agudas e a longo prazo. Conclusões Um diagnóstico preciso e um acompanhamento e tratamento apropriados dos distúrbios neurológicos durante a gravidez são ações exequíveis. Contudo, requerem uma abordagem multidisciplinar, crucial para melhorar os desfechos perinatais.

Why could a woman have three Trisomy 21 pregnancies? - a case report.

Mosaicism, an important cause for recurrent T21, should be suspected in families with more than one affected child wishing to receive prenatal counseling. Fluorescence in-situ hybridization analysis in a large number of cells and in different tissue samples is critical for detecting low-level mosaicism and is a key prognostic factor.

Syphilis in Pregnancy and Congenital Syphilis: Reality in a Portuguese Central University Hospital.

Purpose To evaluate maternal-fetal surveillance and follow-up of infants at risk for congenital syphilis (CS). Methods Retrospective cohort study in a Portuguese Tertiary Referral Hospital. The main inclusion criterion was a positive syphilis serology. The study included all pregnant women that delivered in our hospital between January 2004 and December 2013. The neonates were classified according to their probability of infection based on the Centers for Disease Control and Prevention guidelines. Results Among the 27 pregnancies at risk for CS, 48.2% (n = 13) of the women had a diagnosis during the 1st trimester, and the median gestational age at the end of the treatment was 28 weeks. Inadequate treatment was noted in 44.4% (n = 12) of the women. Adverse pregnancy outcomes were observed in 30.8% of the cases (n = 8), 5 of which had been adequately treated. We found 2 (7.7%) cases with "proven or highly probable CS," 10 (38.5%) with "possible CS," 12 (46.1%) with "less likely CS," and 2 (7.7%) with "unlikely CS." Among the infants, the treatment was successful, except for 1 neurosyphilis case. Conclusion This study highlights many of the difficulties/concerns encountered in the maternal-neonatal management of syphilis. We highlight the importance of assuring the early detection of the infection as a way of guaranteeing the timely treatment, as well as a good compliance to the treatment and follow-up through a more efficient pregnant women surveillance network.

Objetivo Avaliar a vigilância materno-fetal e o acompanhamento de crianças em risco de sífilis congênita (SC). Métodos Estudo de coorte retrospetivo desenvolvido num hospital terciário de referência, cujo principal critério de inclusão foi a presença de serologia positiva para sífilis. O estudo incluiu todas as grávidas admitidas no nosso Hospital entre janeiro de 2004 e dezembro de 2013. Os recém-nascidos foram classificados de acordo com a probabilidade de infeção, com base nas recomendações do Centers for Disease Control and Prevention. Resultados Entre as 27 gravidezes em risco de SC, 48,2% (n = 13) tiveram diagnóstico durante o 1° trimestre; a idade gestacional média no final do tratamento foi de 28 semanas. Em 44,4% (n = 12) das mulheres, o tratamento foi considerado inadequado. Em 30,8% dos casos (n = 8) houve algum evento adverso da gravidez, dos quais 5 foram adequadamente tratados. Em dois dos casos (7,7%) a SC foi provada ou considerada como altamente provável, 10 (38,5%) com SC provável, 12 (46,1%) com SC pouco provável, e 2 (7,7%) com SC improvável. Nos lactentes, o tratamento foi bem sucedido, com exceção de um caso de neurossífilis. Conclusão Este estudo visa realçar muitas das dificuldades/preocupações encontradas na vigilância materno-neonatal dos casos com diagnóstico de sífilis. ublinhamos, não só, a importância de se assegurar a deteção precoce de infeção como forma de se garantir o tratamento atempado, mas também, uma adequada adesão à vigilância/tratamento, através de uma rede mais eficiente entre as diferentes instituições envolvidas no acompanhamento das grávidas.

Acute Onset Neurological Disorders during Pregnancy: A Literature Review.

Objectives To characterize the most common peripheral and central neurological disorders during pregnancy. Methods Original research and review of the literature on neurological complications during pregnancy. We searched for keywords related to the topic on different databases. Results Pregnancy involves physiological changes that can trigger peripheral neurological and/or central nervous system pathologies, which can sometimes be associated with hypertensive disorders. A definitive diagnosis of neurological disorders can be made according to the trimester of pregnancy and the clinical findings. Carpal tunnel syndrome and peripheral facial palsy are common peripheral neurological disorders, more frequent in the second half of pregnancy. Central nervous disorders are more complex and a precise diagnosis must be made in order to improve perinatal outcomes, provide correct management and treatment and to prevent acute and long-term complications. Conclusions It is possible to achieve a precise diagnosis, management and treatment of neurological disorders during pregnancy, but these require a multidisciplinary approach, crucial to improve perinatal outcomes.

Objetivos Caracterizar as alterações neurológicas centrais e periféricas mais comuns durante a gravidez. Métodos Foi efetuada uma revisão da literatura acerca de complicações neurológicas durante a gravidez. Foram utilizadas diversas bases de dados usando palavras-chave relacionadas com o tema. Resultados A gravidez envolve alterações fisiológicas que podem desencadear alterações neurológicas periféricas e/ou do sistema nervoso central, por vezes associadas a distúrbios hipertensivos. Um diagnóstico definitivo pode ser feito tendo em conta o trimestre de gravidez e os achados clínicos encontrados. A síndrome do túnel carpal e a paralisia facial periférica são alterações neurológicas periféricas comuns que ocorrem mais frequentemente na segunda metade da gravidez. As alterações em termos do sistema nervoso central são mais complexas. Um diagnóstico preciso é fulcral, não só para melhorar os desfechos perinatais, mas também para efetuar uma vigilância e tratamento adequados e para prevenir complicações agudas e a longo prazo. Conclusões Um diagnóstico preciso e um acompanhamento e tratamento apropriados dos distúrbios neurológicos durante a gravidez são ações exequíveis. Contudo, requerem uma abordagem multidisciplinar, crucial para melhorar os desfechos perinatais.

Syphilis in Pregnancy and Congenital Syphilis: Reality in a Portuguese Central University Hospital / Sífilis na gravidez e sífilis congênita: realidade de um hospital universitário central português

Abstract Purpose To evaluate maternal-fetal surveillance and follow-up of infants at risk for congenital syphilis (CS). Methods Retrospective cohort study in a Portuguese Tertiary Referral Hospital. The main inclusion criterion was a positive syphilis serology. The study included all pregnant women that delivered in our hospital between January 2004 and December 2013. The neonates were classified according to their probability of infection based on the Centers for Disease Control and Prevention guidelines. Results Among the 27 pregnancies at risk for CS, 48.2% (n = 13) of the women had a diagnosis during the 1st trimester, and the median gestational age at the end of the treatment was 28 weeks. Inadequate treatment was noted in 44.4% (n = 12) of the women. Adverse pregnancy outcomes were observed in 30.8% of the cases (n = 8), 5 of which had been adequately treated. We found 2 (7.7%) cases with "proven or highly probable CS," 10 (38.5%) with "possible CS," 12 (46.1%) with "less likely CS," and 2 (7.7%) with "unlikely CS."Among the infants, the treatment was successful, except for 1 neurosyphilis case. Conclusion This study highlights many of the difficulties/concerns encountered in the maternal-neonatal management of syphilis. We highlight the importance of assuring the early detection of the infection as a way of guaranteeing the timely treatment, as well as a good compliance to the treatment and follow-up through a more efficient pregnant women surveillance network.

Resumo Objetivo Avaliar a vigilância materno-fetal e o acompanhamento de crianças em risco de sífilis congênita (SC). Métodos Estudo de coorte retrospetivo desenvolvido num hospital terciário de referência, cujo principal critério de inclusão foi a presença de serologia positiva para sífilis. O estudo incluiu todas as grávidas admitidas no nosso Hospital entre janeiro de 2004 e dezembro de 2013. Os recém-nascidos foram classificados de acordo com a probabilidade de infeção, com base nas recomendações do Centers for Disease Control and Prevention. Resultados Entre as 27 gravidezes em risco de SC, 48,2% (n = 13) tiveram diagnóstico durante o 1° trimestre; a idade gestacional média no final do tratamento foi de 28 semanas. Em 44,4% (n = 12) das mulheres, o tratamento foi considerado inadequado. Em 30,8% dos casos (n = 8) houve algum evento adverso da gravidez, dos quais 5 foram adequadamente tratados. Em dois dos casos (7,7%) a SC foi provada ou considerada como altamente provável, 10 (38,5%) com SC provável, 12 (46,1%) com SC pouco provável, e 2 (7,7%) com SC improvável. Nos lactentes, o tratamento foi bem sucedido, com exceção de um caso de neurossífilis. Conclusão Este estudo visa realçar muitas das dificuldades/preocupações encontradas na vigilância materno-neonatal dos casos com diagnóstico de sífilis. ublinhamos, não só, a importância de se assegurar a deteção precoce de infeção como forma de se garantir o tratamento atempado, mas também, uma adequada adesão à vigilância/ tratamento, através de uma rede mais eficiente entre as diferentes instituições envolvidas no acompanhamento das grávidas.

Is Preterm Labor Influenced by the Maternal-Fetal Interface?

Preterm labor (PTL) accounts for almost 11% of deliveries, and is a major cause of neonatal morbidity and mortality. T regulatory (Treg) cells may prevent fetal rejection by the maternal immune system under the influence of progesterone. Case control study was conducted to determine Treg cells, IL-10, TGF-ß, and membrane progesterone receptorα (mPRα) in the maternal-fetal interface (placenta), including eight pregnant women with threatened PTL (study group) and 16 normal-delivery women (control group). Comparing study group versus control, mean gestational age of delivery differed significantly (p = 0.02), as did endothelial hyperplasia in the upper half (p = 0.035) and the lower half (p = 0.005) of the placenta. Besides, there was higher expression of mPRα and IL-10 in all layers, while Foxp3 expression occurred equally and only in the decidua. TGF-ß expression was similar in both groups. Preterm group placentas showed higher endothelial hyperplasia in both upper and lower halves of the placenta.
