ABSTRACT Psychomotor performance is a complex function generated by brain and motor systems integration, measured by accuracy, latency, and movement speed. In sports, looking for ways to improve movements is usual. Also, utilising Transcranial Direct Current Stimulation (tDCS) as a non-invasive stimulation technique may produce alterations in psychomotor sports skills. We conducted a systematic review, including experimental studies with sham or control groups in adults reporting tDCS effects on athletes’ psychomotor performance. Cochrane Manual for Systematic Reviews and the statement on systematic reviews and meta-analysis of PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) were followed. PsycINFO, PubMed (central), Scopus, Web of Science, Embase, SPORTDiscus, and Cochrane Library databases were searched. Empirical studies published in English, Spanish, and Portuguese from 2009 onwards and whose primary results presented an effective measure of transcranial direct current stimulation in the psychomotor performance of adult athletes were included. The results list 10 articles, 6 of them entered in the meta-analyses. The articles presented a low risk of bias and low publication bias but great dispersion of stimulation areas.

Resumen Aún cuando los tsunamis son poco frecuentes en el Caribe de Costa Rica, pueden llegar a ser destructivos. En Costa Rica existe la creencia errónea de que no hemos tenido tsunamis. Sin embargo, los autores encontraron reportes relacionados a cinco tsunamis en la costa caribeña de Costa Rica, todos correspondientes a eventos locales. Estos reportes corresponden a dos tsunamis confirmados y tres registros probables de tsunamis. Si bien todos estos tsunamis fueron moderados, algunos de ellos causaron inundaciones y hasta fallecimientos. No es posible establecer un período de recurrencia para los tsunamis ni para los sismos originados en la costa caribeña de Costa Rica. A pesar de esto, sabemos que es sólo cuestión de tiempo para que vuelva a ocurrir un tsunami en nuestras costas, por lo que las autoridades y las comunidades costeras del Caribe deben estar preparadas. Los registros históricos de tsunami brindan una idea de lo que puede pasar en el futuro.

Abstract Even though tsunamis are infrequent in the Caribbean of Costa Rica, they can be destructive. The Costa Ricans mistakenly think our country has not experienced tsunamis. However, the authors found reports of five tsunamis in the Caribbean of Costa Rica, all corresponding to local events. They corresponded to two confirmed tsunamis and three probable tsunamis. Even when all these tsunamis were moderate, they caused flooding and deaths. It is not possible to establish a recurrence period for tsunamis nor earthquakes in the Caribbean coast of Costa Rica. However, tsunamis will happen again in this coast, therefore the authorities and the coastal communities must be prepared. Historical records of tsunamis allow to foresee what can happen in future tsunamis.

Resumen: En Costa Rica, pese a su relativa baja frecuencia, los tsunamis suponen un riesgo en las comunidades costeras. La integración de información geofísica y geológica permite la interpretación de posibles áreas de ruptura para las cuales se evalúa la propagación e inundación de tsunamis a través de simulaciones numéricas en el Caribe de Costa Rica y zonas adyacentes al sismo tsunamigénico ocurrido en 1991 (Mw 7,7). Los resultados muestran que el peligro de inundación por tsunamis en el Caribe de Costa Rica devenga particularmente de sismos generados en el Cinturón Deformado del Norte de Panamá. Además, se muestra que sismos de mediana magnitud (Mw~7) en fallas de alto ángulo, pueden provocar tsunamis locales. Este trabajo puede ser usado como base para la generación de mapas de evacuación y concientización del peligro de tsunamis en la zona.

Abstract In Costa Rica, despite their relative low frequency, tsunamis could pose risk to coastal communities. The integration of geophysical and geological information allows the interpretation of possible rupture areas for which tsunami propagation and inundation is evaluated through numerical modeling along the Caribbean of Costa Rica and areas adjacent to the tsunamigenic earthquake that occurred in 1991 (Mw 7,7). The results show that the tsunami threat in the Caribbean of Costa Rica arises particularly from earthquakes generated in the North Panama Deformation Belt. In addition, it is shown that medium-magnitude earthquakes (Mw ~ 7) in high-angle faults can cause local tsunamis. This work can be used as a basis for the generation of evacuation maps and awareness of the tsunami threat in the area.

Abstract Background: Maternal mortality rates in Brazil remain above the goals established by the United Nations Sustainable Development Goals. Heart disease is estimated to affect 4% of all pregnancies and remains by itself the main indirect obstetric cause of maternal death. In the last decades, a significant improvement in the prognosis of heart diseases has made pregnancy possible in women with heart disease and provided better maternal and fetal outcomes. Objective: To establish a multicenter Brazilian Registry of pregnant women with heart disease; to study the causes of immediate and late maternal mortality; and to assess the prevalence of heart disease in the country’s macro-regions. Method: This is an observational study, with retrospective and prospective stages, of the clinical and obstetric progression of pregnant women with heart disease. These women consecutively received care during pregnancy and will be followed up for up to a year after delivery at public and private hospitals with infrastructure for the execution of this project, a principal investigator, and approval by Ethics and Research Committees. Results: Our results will be presented after data collection and statistical analysis, aiming to demonstrate immediate and late maternal mortality rates, as well as the prevalence of heart disease in the country and its cardiovascular and obstetric complications during pregnancy. Conclusion: REBECGA will be the Brazilian Registry of heart disease and pregnancy and it will contribute to planning preventive measures, raising financial resources for the improvement of high-risk prenatal care, and reducing immediate and late maternal mortality due to heart disease.

ABSTRACT Objective: To determine the working conditions, habits and lifestyles related to the multimorbidity of older adults with subsistence jobs in the center of Medellín-Colombia, 2016. Material and Methods: Cross-sectional study with primary sources of information to a census of 686 workers, surveyed After obtaining informed consent, in 2016. For this study, 153 workers aged ≥60 years were taken. Univariate, bivariate and multivariate analysis, to study their multimorbidity and factors associated with their work. Results: 77,0% were between 60-69 years old; mainly men, 56,0% earned <500,000 Colombian pesos. They were > 20 years old in their trade. 62,0% presented multimorbidity, mainly due to diabetes; hypertension; obesity and depressive symptoms. They explained a higher prevalence of multimorbidity (p<0,05) working near wastewater (RPA=3,38.CI=1,27; 8,96), not having a schedule for food consumption (RPA=3,01.CI=1,25;7,27) and consuming food alone (RPA=3,28.CI=1,31; 8,18). Conclusion: The conditions that explain multimorbidity in these workers can be reversed with health promotion and disease prevention actions, led by the State and with its active participation.

Abstract Following the 2004 Indian Ocean and the 2011 Tohoku earthquakes and tsunamis, there has been steady progress in tsunami science and preparedness worldwide. Currently, there are four Tsunami Warning and Mitigation Systems as Intergovernmental Coordination Groups (ICGs) coordinated by IOC/UNESCO. They include tsunami monitoring, warning, and response. They are mostly based on scientific knowledge including tsunami hazard assessments, 24/7 monitoring systems, agreed operational standard procedures (SOPs), redundant communication and community response mechanisms. Costa Rica has greatly increased its tsunami preparedness during the past six years, after the creation of SINAMOT (Sistema Nacional de Monitoreo de Tsunamis). SINAMOT works by characterizing the tsunami threat, encouraging, and supporting community preparedness, strengthening the existing tsunami warning SOPs and maintaining the sea level monitoring network. SINAMOT articulates with stakeholders and decision makers such as seismic monitoring networks, national and local government, emergency managers and committees. Four communities in Costa Rica have been recognized as Tsunami Ready by IOC/UNESCO, four more are recognized with pending guidelines and five more are working on fulfilling the requirements. Despite all the progress made, there is still plenty of work to do to have a safe and predictable ocean regarding tsunamis. Atypical tsunami sources are not yet incorporated in hazard assessments, there are many gaps in sea level monitoring, and capacity building is required in many aspects so that developing countries can be more autonomous in their tsunami preparedness and response. Our major challenges today worldwide are with staffing and funding, both to kick-off and to sustain the mentioned activities. Specifically, Costa Rica requires more physical oceanographers and geoscientists working on tsunami science and more funding to study the ocean (including sea level gauges and tsunami hazards assessment) to support the tsunami and other coastal hazard warning systems. This requires working together with communities and stakeholders to increase tsunami preparedness.

RESUMEN Objetivos: reportar el caso de un embarazo cervical (EC) que recibió manejo conservador exitoso y realizar una revisión de la literatura sobre el tratamiento médico y quirúrgico conservador. Materiales y métodos: se presenta el caso de una paciente con embarazo cervical, quien recibió manejo farmacológico con metotrexate (MTX) y posterior legrado con evolución clínica satisfactoria. Se realizó una búsqueda de artículos en Medline vía PubMed, LILACS, SciElo y Google académico con los términos: “cervical ectopic pregnancy”, “conservative treatment”, “curettage”, “methotrexate”, “uterine artery embolization” “hysteroscopy”. Se seleccionaron reportes y series de caso, pacientes con embarazo cervical diagnosticado por ultrasonido, de cualquier edad gestacional, sometidas tratamiento médico o quirúrgico conservador. Resultados: se incluyeron 22 estudios; se identificaron 95 pacientes con EC tratados con MTX, con tratamiento exitoso en 93. La complicación más frecuente fue la hemorragia en 12 %; el 26 % requirió tratamiento quirúrgico complementario. Cada vez más, la embolización de arterias uterinas (EAU) se realiza de manera preventiva (7 casos) antes del legrado o del tratamiento con MTX. La histeroscopia es otra alternativa reciente (20 casos). En 2 casos se requirió histerectomía abdominal, uno de los cuales fue un embarazo ístmico cervical. Conclusiones: el tratamiento con MTX sigue siendo el más frecuentemente utilizado. La dilatación y el curetaje con taponamiento endocervical puede ser una opción por considerar en el manejo de urgencia del EC en instituciones de atención primaria. En instituciones donde se dispone de tecnologías de alta complejidad, la embolización de arterias uterinas previa a los procedimientos quirúrgicos y la histeroscopia son opciones que se deben considerar. Dado que actualmente es posible el diagnóstico temprano del EC, se requieren estudios multicéntricos que comparen las diferentes alternativas de manejo para una mejor evaluación de su seguridad y efectividad.

ABSTRACT Objectives: To report a case of cervical pregnancy (CP) treated successfully with a conservative approach, and to conduct a review of the literature regarding conservative medical and surgical treatment. Materials and Methods: Patient with cervical pregnancy treated pharmacologically with methotrexate (MTX) followed by dilation and curettage, with a satisfactory clinical course. A search of articles was conducted in Medline via PubMed, LILACS, SciElo and Google Scholar using the terms “cervical ectopic pregnancy,” “conservative treatment,” “curettage,» “methotrexate,” “uterine artery embolization,” “hysteroscopy.” Reports and case series were selected of patients with cervical pregnancy diagnosed on ultrasound at any gestational age, subjected to conservative medical or surgical treatment. Results: A total of 22 studies were included; 95 patients with CP treated with MTX were identified, 93 of them successfully treated. The most frequent complication was bleeding in 12%; 26% required complementary surgical treatment. Increasingly, uterine artery embolization (UAE) is carried out preventatively (7 cases) before curettage or treatment with MTX. The hysteroscopy is another recent alternative (20 cases). Abdominal hysterectomy was required in two cases, one of which was a cervico-isthmic pregnancy. Conclusions: Treatment with MTX continues to be the most frequent strategy. Dilation and curettage with endocervical plugging may be an option to consider in the emergency management of EP in primary care institutions. In institutions equipped with high complexity technology, uterine artery embolization before the surgical procedure and histeroscopy are options to be considered. Considering that early diagnosis of EP is now possible, multi-center studies comparing different management options are needed for better assessment of their safety and effectiveness.

RESUMO Neste estudo, foi avaliado o desempenho de um reator em bateladas sequenciais com biofilme de leito móvel operado pelo processo anaeróbio-anóxico-óxico (A2O), aplicado à remoção simultânea de material orgânico, nitrogênio e fósforo de esgoto sanitário. Utilizaram-se dois reatores com volume útil de 36 L cada, sendo que um deles recebeu anéis plásticos móveis do tipo Kaldnes®, com área superficial específica estimada em 310 m2/m3 que ocuparam 50% do volume útil do reator (denominado aqui de MBSBBR). O estudo foi conduzido com tempo de retenção de sólidos (TRS) de 12 dias, tempo de retenção hidráulico (TRH) de 6 horas, taxa de alimento/microrganismo (A/M) de 0,4 a 0,5 gDQO/SSV.d, oxigênio dissolvido (OD) na faixa de 0,3-0,8 mgO2/L e taxas de aplicação de carga orgânica, nitrogênio e fósforo de 47,2 gDQO/L.d, 5,4 gNTK/L.d e 0,4 gP/L.d, respectivamente. Os resultados de eficiência de remoção de demanda química de oxigênio (DQO), N-NH3 e fósforo foram de 91,1, 90,5 e 85,4% para o reator MBSBBR e de 89,5, 91,6 e 84,4% para o reator RBS, respectivamente. Os resultados do teste estatístico de ANOVA foram aplicados às principais variáveis estudadas, e os valores convergiram para valores de f observado < f crítico . Dessa forma, considera-se que houve similaridade de desempenho nos reatores MBSBBR e RBS. Conclui-se que a introdução do meio suporte não trouxe benefícios ao tratamento em termos de remoção de nutrientes. No entanto, o estudo mostrou que é possível de se obter elevada remoção de nitrogênio, em baixas concentrações de OD, o que se torna vantajoso para o tratamento de esgoto com elevada concentração de nitrogênio.

ABSTRACT In this study, the performance of a reactor in sequential batch with mobile bed biofilm operated by the anaerobic-anoxic-oxic (A2O) process, applied to the simultaneous removal of organic material, nitrogen and phosphorus from sanitary sewage was evaluated. Two reactors with a useful volume of 36 liters each were used, one of them receiving Kaldnes® type mobile plastic rings, with a specific surface area estimated at 310 m2/m3, which occupied 50% of the reactor’s useful volume (MBSBBR). The study was conducted with 12-day solid retention time (SRT), 6 hour hydraulic retention time (HRT), food/microorganism (F/M) ratio of 0.4 to 0.5 gCOD/VSS.d, dissolved oxygen (DO) in the range of 0.3-0.8 mgO2/L and application rates of organic load, nitrogen and phosphorus of 47.2 gCOD/L.d, 5.4 gTNK/L.d and 0.4 gP/L.d, respectively. The efficiency of chemical oxygen demand (COD), N-NH3 and Phosphorus removal was of 91.1%, 90.5% and 85.4% for the MBSBBR reactor and 89.5%, 91.6% and 84.4% for the RBS reactor, respectively. The results of the statistical ANOVA test were applied to the main variables studied and the values converged to values of f observed < f critical . In this way, it is considered that there was a similarity of performance between the MBSBBR and RBS reactors. It is concluded that the introduction of the support medium did not bring benefits to the treatment in terms of nutrient removal. However, the study showed that it is possible to obtain high nitrogen removal at low concentrations of DO, which is advantageous for the sewage treatment with high nitrogen concentration.

Resumen Hicimos caracterizaciones rápidas de avifauna en dos complejos de páramo (Frontino-Urrao y Sonsón) en el departamento de Antioquia, Colombia, en el límite superior de bosques nublados, zonas de transición y páramos. Registramos 197 especies de aves (40 familias), de las cuales 7 presentan alguna categoría de amenaza, 1 está casi amenazada, 5 son endémicas, 15 casi endémicas, 4 son migratorias boreales y 1 es migratoria austral. Señalamos 12 especies de importancia, ya sea por su grado de amenaza nacional o por presentar ampliación en su rango de distribución geográfica o altitudinal.

Abstract We characterized bird communities in two paramo complexes (Frontino-Urrao and Sonsón) in the department of Antioquia, Colombia, including the transition zones and the upper boundaries of cloud forests. We recorded 197 bird species (40 families), of which 7 presented some threat category, 1 is almost threatened, 5 are endemic, 15 near endemic, 4 boreal migratory species and 1 austral migratory species. We point out 12 species that are relevant, either due to their degree of national threat or because they represent geographic or altitudinal range extensions.
