RESUMO
Preeclampsia (PE) is a multifactorial pregnancy disorder characterized by hypertension and proteinuria, posing significant risks to both maternal and fetal health. Despite extensive research, its complex pathophysiology remains incompletely understood. This narrative review aims to elucidate the intricate mechanisms contributing to PE, focusing on abnormal placentation, maternal systemic response, oxidative stress, inflammation, and genetic and epigenetic factors. This review synthesizes findings from recent studies, clinical trials, and meta-analyses, highlighting key molecular and cellular pathways involved in PE. The review integrates data on oxidative stress biomarkers, angiogenic factors, immune interactions, and mitochondrial dysfunction. PE is initiated by poor placentation due to inadequate trophoblast invasion and improper spiral artery remodeling, leading to placental hypoxia. This triggers the release of anti-angiogenic factors such as soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng), causing widespread endothelial dysfunction and systemic inflammation. Oxidative stress, mitochondrial abnormalities, and immune dysregulation further exacerbate the condition. Genetic and epigenetic modifications, including polymorphisms in the Fms-like tyrosine kinase 1 (FLT1) gene and altered microRNA (miRNA) expression, play critical roles. Emerging therapeutic strategies targeting oxidative stress, inflammation, angiogenesis, and specific molecular pathways like the heme oxygenase-1/carbon monoxide (HO-1/CO) and cystathionine gamma-lyase/hydrogen sulfide (CSE/H2S) pathways show promise in mitigating preeclampsia's effects. PE is a complex disorder with multifactorial origins involving abnormal placentation, endothelial dysfunction, systemic inflammation, and oxidative stress. Despite advances in understanding its pathophysiology, effective prevention and treatment strategies remain limited. Continued research is essential to develop targeted therapies that can improve outcomes for both mothers and their babies.

The avian vampire fly Philornis downsi (Dodge & Aitken) (Diptera: Muscidae) is native to continental South America and the Caribbean, but invasive in the Galapagos Archipelago. The larvae of P. downsi feed on the blood and tissues of the nestlings of 75% of the small land bird species that are endemic or native to Galapagos, causing high in-nest mortality and severe population declines in some species. Efficient trapping techniques are vital to safeguarding these birds in the short term as well as for monitoring fly populations, but basic information about the ecology of the fly is still needed to help develop a species-appropriate trapping method. In this study, we used a novel trapping regime with a vertical distribution to make inferences about P. downsi's behavioral and spatial ecology and to optimize trap catch. Our results showed that male and female P. downsi were trapped in greater numbers below the canopy (3.1-7.5 m), lower down than other commonly caught insect species (5.1-11.5 m). Notably, the effect of trap height remained consistent across seasons and different weather conditions. These findings suggest that P. downsi tend to move at heights where their hosts nest (at or below the canopy) and do not spend time above the canopy. This also makes it unlikely that strategies such as hill-topping or aerial swarming are being used to locate mates. As such, trapping and control efforts should be focused below the canopy in forests with similar canopy heights to effectively capture P. downsi and reduce bycatch of other insects.

Objetivo: investigar el efecto de una intervención a distancia sobre los síntomas de ansiedad y el consumo de alcohol en usuarios del servicio de Atención Primaria de Salud. Método: estudio cuasiexperimental, realizado con 1270 participantes que respondieron al Alcohol Use Disorders Identification Test y al State-Trait Anxiety Inventory 6. De estos, 1033 encuestados obtuvieron puntajes de síntomas de ansiedad moderada/grave (STAI-6 > 3) y consumo de alcohol de riesgo moderado/grave (AUDIT-C>3), y recibieron las intervenciones mediante llamada telefónica con un seguimiento de siete y 180 días. Para analizar los datos se utilizó un modelo de regresión de efectos mixtos. Resultados: el efecto de la intervención realizada fue positivo para reducir los síntomas de ansiedad entre T0 y T1 (µ=1,6 p<0,001) y para reducir el patrón de consumo de alcohol entre t1 y t3 (µ=1,57 p< 0,001). Conclusión: los resultados del seguimiento sugieren que la intervención tuvo un efecto positivo en la reducción de la ansiedad y el patrón de consumo de alcohol que tiende a mantenerse en el tiempo. Existe evidencia de que la intervención propuesta puede ser una alternativa para la atención preventiva en salud mental, en situaciones donde se comprometa la accesibilidad del usuario o del profesional.

RESUMO
To evaluate the effectiveness of a brief group intervention (BGI) in reducing the use of alcohol and increasing the readiness to change in men with risky and harmful alcohol use. A randomized clinical trial with follow-ups at 30 and 90 days that was conducted in a primary health care (PHC) facility in the central region of São Paulo (Brazil). A total of 112 men were randomized to the experimental group (EG) (n = 55) or the control group (CG) (n = 57). To identify the pattern of alcohol use and the readiness to change, the Alcohol Use Disorders Identification Test (AUDIT) and the readiness to change (RTC) rule were used. The EG received a BGI session applied by nurses using the Feedback, Responsibility, Advice, Menu of options, Empathy, Self-efficacy (FRAMES) model. The CG was instructed to continue with the standard service of the unit after an initial interview. Intergroup analyses using the generalized equation estimation (GEE) method were performed. A significant difference in the pattern of use was observed between the EG and CG at follow-up evaluated (EG T1 (7.73 ± 5.14), CG T1 (12, 48 ± 5.62)) and EG T2 (6.65 ± 4.83), CG T2 (11.68 ± 6.65)). When compared the baseline (T0) measures (13.04) with the last time (T2) (6.65) at EG, it was identified a reduction of 6.39 in the AUDIT score. Differences between groups were found for readiness to change at follow-up ((EG T1 (8.50 ± 2.44) and CG T1 (5.67 ± 3.10) and (EG T2 (8.80 ± 1.73) and CG T2 (5.36 ± 3.33)), when contrasting with the baseline. The data suggest that the BGI was effective when compared to the control condition, as there was a reduction in risky and harmful use of alcohol for low-risk use, according to the alcohol use scores, and an increase in the stages of readiness to change.

The present study identified and compared the attitudes of nursing students from North and South American countries towards alcohol, alcohol use disorders and persons with alcohol use disorders (AUDs). A cross-sectional design and survey approach were used. The sample consisted of 327 nursing students recruited from four nursing schools in metropolitan regions of North and South America. The questionnaire contained questions about sex, age, marital status, home country and other questions about training in substance use disorders during nursing education and previous experiences with substance use disorder patients. To identify nursing students' attitudes, validated English, Spanish and Portuguese versions of the attitudes scale for alcohol, alcoholism and persons with AUDs (EAFAA) were applied. Comparison of the four groups suggested that nursing students in the United States demonstrated more positive attitudes than students from Colombia, Mexico and Brazil. Similar positive attitudes were observed towards individuals with AUDs. Results of the attitudes towards the aetiology of AUDs showed positive attitudes in all samples, suggesting a contemporary understanding of AUDs. Nursing students' attitudes were associated with home country and training in substance use disorders during nursing education. Nursing students' attitudes were generally positive across countries. Idiosyncratic cultural and educational aspects in these countries and world regions likely significantly influenced the attitudes of nursing students towards alcohol and associated issues.

Infusions and poultices prepared from the aerial parts of Baccharis heterophylla Kunth (Asteraceae) are widely used in Oaxaca (Mexico) for relieving painful and inflammatory complaints. Therefore, the antinociceptive potential of an aqueous extract (31.6-316 mg/kg, p.o.) and essential oil (30-177 µg/paw, i.pl.) of the plant was assessed using the formalin test. Both preparations inhibited the formalin-induced nociception response (100-316 mg/kg and 100-177 µg/paw, respectively) during the test's second phase. Chemical analysis of the aqueous extract revealed that the major active components were chlorogenic acid (1), 3,4-di-O-(E)-caffeoylquinic acid (2), 3,5-di-O-(E)-caffeoylquinic acid (3), 4,5-di-O-(E)-caffeoylquinic acid (4), 3,5-di-O-(E)-caffeoylquinic acid methyl ester (5), apigenin (6), genkwanin (7), acacetin (8). Compounds 1-5 and 8 are new for B. heterophylla. A high-pressure liquid chromatographic method for quantifying chlorogenic acid (1) and di-caffeoylquinic acids 2-4 in the plant was developed and validated. Analyses of the essential oil and the headspace solid-phase microextraction products, via gas-chromatography-mass spectrometry, revealed that the major volatiles were ß-pinene, myrcene, D-limonene, ß-caryophyllene, and α-caryophyllene, which have demonstrated antinociceptive properties.

BACKGROUND: Hyperhomocysteinemia, a thrombotic risk factor, may have several causes. Among the genetic causes of hyperhomocysteinemia, there are polymorphisms in the enzymes methylenetetrahydrofolate reductase (C677T) and cystathionine ß-synthase (C699T, C1080T, and 844ins68). Although the frequency of hyperhomocysteinemia in our country is high, there is no evidence about the frequencies of these polymorphisms. METHODS: We analyzed 80 healthy individuals from several regions in our country. We evaluated the fasting and post-oral methionine load plasma Hcy and the genotypes in order to obtain the allele frequencies of the polymorphisms C677T of methylenetetrahydrofolate reductase and C699T, C1080T, and 844ins68 of the cystathionine ß-synthase. RESULTS: No individual had deficiency of folic acid, vitamins B12, or B6, but 80% had post-oral methionine load hyperhomocysteinemia. We found a significant increase in the Hcy plasma concentration associated with age and gender. Only the polymorphism C1080T was significantly associated with hyperhomocysteinemia. CONCLUSION: There is an association between fasting and post-oral methionine load plasma Hcy concentrations with the allelic frequencies of the polymorphisms C669T, 844ins68, and C1080T of the cystathionine ß-synthase and C667T of the methylenetetrahydrofolate reductase in healthy Mexican individuals. As compared with individuals with normal fasting or post-oral methionine load Hcy plasma levels, only C1080T was significantly associated with hyperhomocysteinemia.
RESUMO
Attitudes of health professionals have an effect on the quality of care provided to individuals with alcohol use disorders. The identification of health professionals' attitudes supports strategies that promote positive attitudes and improve the quality of the health care provided to this population. This is a descriptive cross-sectional study with 831 health professionals. Data were collected using the scale of attitudes toward alcohol, alcohol use disorder, and individuals with alcohol use disorders. Pearson test, Analysis of Variance, and Bayesian linear regression were used to analyze the data. There was a predominance of positive attitudes among all professional categories, with the exception of attitudes toward the etiology of alcohol use disorder and attitudes toward alcoholic beverages and their use. The respondent's age and professional category influenced his or her attitudes toward alcohol and associated issues. There are differences in the attitudes of professionals from different professional groups, which may contribute to inconsistencies in the care provided for individuals with alcohol use disorders. The results of our study suggest that strategies regarding the training and continuing education of health professionals that consider the particularities of each profession be instituted to improve professionals' attitudes, thus improving their ability to address issues related to alcohol use disorders and encourage alcoholic patients to engage in treatment.

Introducción: La acelerada transformación de los usos del suelo en los Andes colombianos han afectado la diversidad y la provisión de servicios ecosistémicos. Objetivo: Se caracterizó la estructura y composición florística, junto a la estimación del carbono almacenado en biomasa de bosques primarios intervenidos y pasturas con árboles en Santa Isabel, Tolima. Métodos: En cada sistema, se establecieron cinco parcelas de muestreo: rectangulares de 1 000 m2 cada una en bosques y circulares de 707 m2 en pasturas, para medir todos los individuos con diámetro a 1.30 m de altura, ≥10 cm. La biomasa se estimó a partir de modelos alométricos multi-especies y un modelo genérico en el caso de biomasa abajo del suelo. Resultados: En el bosque se registró una abundancia promedio de 642 ± 125 individuos/ha, se encontraron 25 familias, 39 géneros, 43 especies y morfoespecies en 0.5 ha de muestreo. Quercus humboldtii y Ladenbergia macrocarpa fueron las especies con el mayor Índice de Valor de Importancia (IVI = 32.5 y 11.2, respectivamente) en los bosques. En pasturas se encontraron 175.0 ± 21.3 individuos/ha, pertenecientes a 8 familias, 9 géneros, 10 especies y morfoespecies en 0.35 ha de muestreo. Eugenia spp. y Weinmannia pubescens tuvieron la mayor importancia ecológica (19.5 y 17.6 %, respectivamente) en pasturas. El bosque almacenó en promedio 125.0 ± 30.0 t C/ha, comparado con 18.4 ± 1.8 t C/haen pasturas. Conclusiones: Estos hallazgos muestran alta capacidad de almacenamiento de carbono en estos usos del suelo, lo cual contribuye a mantener o disminuir la concentración de gases de efecto invernadero en la atmósfera, y por ende, son un referente que permite desarrollar estrategias de conservación, con miras a mitigar el cambio climático.
Introduction: The accelerated transformation of land uses in the Colombian Andes has affected diversity and the provision of ecosystem services. Objective: The structure and floristic composition and the estimation of the carbon stored in biomass of intervened primary forests and pastures with trees in Santa Isabel, Tolima, was described. Methods: In each system, five sampling plots were established: rectangular of 1 000 m2 each in forests and circular of 707 m2 in pastures to measure all individuals with a diameter of 1.30 m in height, ≥10 cm. The biomass was estimated from multi-species allometric models and a generic model in the case of below-ground biomass. Results: In the forest, an average abundance of 642 ± 125 individuals / ha was recorded, finding 25 families, 39 genera, 43 species and morphospecies in 0.5 ha of sampling. Quercus humboldtii and Ladenbergia macrocarpa were the species with the highest Importance Value Index (IVI = 32.5 and 11.2, respectively) in the forests. In pastures, 175.0 ± 21.3 individuals / ha were found, belonging to 8 families, 9 genera, 10 species and morphospecies in 0.35 ha of sampling. Weinmannia pubescens and Eugenia spp. had the greatest ecological importance (19.5 and 17.6 %, respectively) in pastures. The forest stored an average of 125.0 ± 30.0 t C/ ha, compared to 18.4 ± 1.8 t C/ha in pastures. Conclusions: These findings show high carbon storage capacity in these land uses, which contributes to maintain or decrease the concentration of greenhouse gases in the atmosphere, and therefore, are a benchmark that allows to develop conservation strategies, with a view to mitigate climate change.

AIM: Building strategies for the country-level dissemination of Kangaroo mother care (KMC) to reduce the mortality rate in preterm and low birth weight babies and improve quality of life. KMC is an evidence-based healthcare method for these infants. However, KMC implementation at the global level remains low. METHODS: The international network in Kangaroo mother brought 172 KMC professionals from 33 countries together for a 2-day workshop held in conjunction with the XIIth International KMC Conference in Bogota, Colombia, in November 2018. Participants worked in clusters to formulate strategies for country-level dissemination and scale-up according to seven pre-established objectives. RESULTS: The minimum set of indicators for KMC scale-up proposed by the internationally diverse groups is presented. The strategies for KMC integration and implementation at the country level, as well as the approaches for convincing healthcare providers of the safety of KMC transportation, are also described. Finally, the main aspects concerning KMC follow-up and KMC for term infants are presented. CONCLUSION: In this collaborative meeting, participants from low-, middle- and high-income countries combined their knowledge and experience to identify the best strategies to implement KMC at a countrywide scale.

Objetivos: La cirugía endoscópica del seno frontal es quizá uno de los procedimientos más complejos en el manejo endoscópico de los senos paranasales debido a su localización y a las múltiples variantes anatómicas que pueden encontrarse durante su disección. Es indispensable conocer al detalle la anatomía quirúrgica de esta región en nuestra población, para optimizar la planeación quirúrgica de los pacientes. Actualmente en nuestro país se desconoce la frecuencia de estas variaciones. El objetivo del proyecto es evaluar la frecuencia de las variables anatómicas del seno frontal y realizar un estudio radio-anatómico en una muestra de pacientes en Colombia. Diseño del estudio: Observacional, descriptivo de tipo transversal. Métodos: Muestra aleatorizada de 406 tomografías computarizadas de senos paranasales que incluyeron 812 senos frontales recolectados durante el año 2018 Resultados: La celdilla suprabular fue la más comúnmente reportada con una frecuencia de 59.61%. La segunda celdilla fue la supra agger nasi con una frecuencia de 57.88%, seguido de la celdilla supra agger frontal (25.12%), celdilla suprabular frontal (22.17%), celdillas supraorbitarias (34.98%) y las celdilla frontal intersinusal (24,14%). La arteria etmoidal anterior se reportó colgante en un 31.28% y el diámetro AP más frecuente fue entre 5 -10 milímetros. Conclusiones: Para realizar una sinusotomía frontal endoscópica de forma adecuada es necesario conocer al detalle la anatomía del receso del seno frontal. Las diferentes variantes radio-anatómicas son muy frecuentes en el grupo poblacional estudiado. Creemos que este trabajo permitirá a los cirujanos un mejor entendimiento de esta región de difícil acceso quirúrgico en nuestra población.

Objectives: Endoscopic frontal sinus surgery is perhaps, one of the most complex procedures in the endoscopic sinus surgery, due to its anatomical location and the multiple anatomical variants that can be found. It is essential to know in detail the anatomy of this region in order to obtain a better understanding for the surgical planning. Currently, the frequency of these anatomical variations remains unknown in our country. Therefore, the objective of the study is to evaluate the frequency of the anatomical variants of the frontal sinus and to carry out a radio-anatomic study in a sample of patients from Colombia. Study design: Observational, cross-sectional descriptive. Methods: Randomized sample of 406 CT scan of the paranasal sinuses that included 812 frontal sinuses collected during the year 2018. Results: The supra bulla cell was the most frequently reported with a frequency of 59.61%. The second cell was the supra agger (57.88%) followed by supra agger frontal cell (25.12%), supra bulla frontal cell (22.17%), supraorbital ethmoid cells (34,98%) and frontal septal cell (24,14%) . The anterior ethmoidal artery was found hanging in 31.28% and the most frequent AP diameter was between 5 -10 mm. Conclusions: To perform an appropriate endoscopic frontal sinusotomy, it is necessary to know in detail the anatomy of the frontal sinus recess. The different radio-anatomical variants of the frontal sinus are very frequent in the population group studied. We believe that this study will allow surgeons to obtain a better understanding of this anatomical region of difficult surgical access.

Sleep disturbances are common in the third trimester of pregnancy and generate changes in the secretion of melatonin in pregnant women who sleep less than eight hours or have sleep disturbances, which promote various physiological changes in the mother that in turn result in low birth weight (LBW) in the fetus. LBW is associated with a phenomenon known as "metabolic programming," in which the fetus is subjected to a stressful situation that results in irreversible metabolic alterations that predispose it to the development of obesity in adulthood.
En el tercer trimestre del embarazo son frecuentes las alteraciones del sueño, las cuales generan cambios en la secreción de melatonina en mujeres gestantes que duermen menos de ocho horas o presentan alteraciones de sueño, promoviendo diversos cambios fisiológicos en la madre, que a su vez derivan en bajo peso al nacimiento (BPN) en el producto. El bajo peso al nacimiento está asociado con un fenómeno conocido como "programación metabólica", en la que el feto es sometido a estrés que tiene como resultado alteraciones metabólicas irreversibles que lo predisponen al desarrollo de obesidad en la edad adulta.

RESUMO Objetivo: identificar as atitudes dos enfermeiros colombianos frente ao álcool, ao alcoolismo e ao alcoolista, verificando sua relação com variáveis de interesse no estudo. Método: estudo do tipo transversal, cujos dados foram coletados durante os anos 2014 e 2015, utilizando-se a Escala de atitudes frente ao álcool, ao alcoolismo e à pessoa com transtornos relacionados ao uso de álcool, versão em espanhol. A amostra constituiu-se de 303 enfermeiros de instituições de saúde de Bogotá, na Colômbia. Resultados: observaram-se atitudes negativas em 56,8% dos participantes, frente às relações interpessoais com o usuário no trabalho e frente à etiologia do alcoolismo. Os fatores associados foram: idade, tempo de graduação e frequência no atendimento às pessoas com transtornos relacionados ao uso do álcool. Conclusões: os profissionais de enfermagem apresentaram atitudes ambivalentes frente ao fenômeno. Sugere-se a replicação desse estudo em países da América Latina, na busca de mapear a atual situação desse fenômeno no hemisfério sul americano.

ABSTRACT Objective: To identify the attitudes of Colombian nurses towards alcohol, alcoholism and alcoholics, verifying their relationship with variables of interest in the study. Method: Cross-sectional study whose data was collected in 2014 and 2015, through the use of the Scale of Attitudes towards Alcohol, Alcoholism and Alcoholics, Spanish version. The sample consisted of 303 nurses from health institutions of Bogotá, Colombia. Results: Negative attitudes regarding interpersonal relationships with alcohol users in health care units and the etiology of alcoholism were observed in 56.8% of the participants. The associated factors were age, time elapsed since completion of the undergraduate nursing course, and frequency of care provided to individuals with alcohol use disorders. Conclusions: The nursing professionals had ambivalent attitudes towards the phenomenon. Replication of this study in Latin American countries is suggested, in order to map the current status of this phenomenon in the South American hemisphere.
