RESUMO
Seminal plasma is intimately connected to sperm physiology and particularly in South American Camelids, has demonstrated to be involved in multiple physiological reproductive events. Different percentages of seminal plasma (0%, 10% and 50%) were added to thawed llama semen samples with the objective of evaluating the interaction with cryopreserved sperm over time (0, 1.5 and 3 hr at 37°C). A total of 20 ejaculates from five adult llama males (n = 5; r = 4) were evaluated. A significant decrease in sperm motility, membrane function and live sperm was observed in all thawed samples (0%, 10% and 50%) at 0 hr when compared to raw semen. Neither morphology nor chromatin condensation was altered in all thawed samples (p > .05), but a significant increase in the percentage of spermatozoa with fragmented DNA was observed after thawing all samples versus raw semen. When evaluating thawed samples over time, a significant decrease of motility and membrane function was observed, while the percentages of total live sperm were preserved over the 3 hr of incubation in all final concentrations evaluated. To conclude, the addition of 10% or 50% of seminal plasma was incapable of preserving motility or membrane function of frozen-thawed llama sperm during 3 hr of incubation.

Obesity is a widely recognized risk factor for several diseases, reaching an epidemic magnitude worldwide. Natural polyphenols may improve blood lipids and body weight, but their clinical relevance in the general population remains unclear. Thus, we aimed to analyze the relationship of intake of Ilex paraguariensis (I. paraguariensis) beverages to lipid profiles and body weight in a large patient population. Patients were recruited to participate in an educational program to change habits to a healthy lifestyle. Anamnesis, clinical and laboratory assessments were conducted at study enrollment and during followup. I. paraguariensis beverages were defined according to preparation as obtained by repeated cold water extraction (CWE), hot water infusions, or water and sugar decoction. Heavy drinkers were defined as those persons consuming >1 L/day of one or more preparation types. Participants (N = 18,287) aged ≥18 years entered the study. Overall prevalence of I. paraguariensis consumption was 91.2%. All three forms were drunk by 35.7%, whereas CWE + hot water infusion and CWE alone by 28.4% and 14.5% participants, respectively. Heavy CWE drinkers had lower total cholesterol (191.4 ± 49.4 vs. 194.6 ± 48.3 mg/dl, p = .02) and lower lowdensity lipoprotein cholesterol (118.6 ± 38.9 vs. 121.2 ± 47.1 mg/dl, p = .001), but body weight was higher (81.1 ± 16.8 vs. 77.2 ± 16.4 kg, p < .0001) compared with moderate drinkers. Fasting glucose was lower (104.5 ± 48.7 vs. 107.2 ± 49.5 mg/dl, p < .001), and consumption of carbohydrates was higher (36.3% vs. 28.7%, p < .001). A lowlipids highbodyweight paradox could be observed in a population of heavy drinkers of I. paraguariensis beverages. Induced hypoglycemia and compensatory higher intake of refined carbohydrates may represent a possible cause.

OBJECTIVE: Cardiovascular diseases are the leading cause of mortality in the world. Although most of them are preventable, their prevalence continues to increase. The objective of this study was to estimate the prevalence of cardiovascular risk factors in an urban ambulatory adult hospital population in Asunción, Paraguay. METHODS: A cross-sectional study was undertaken in the population of patients enrolled in the AsuRiesgo prospective study on the prevention of cardiovascular disease, which focuses on promoting a healthy lifestyle. Patients 18 years of age or older who were encountered in doctors' waiting rooms in a tertiary care hospital were invited to participate. Each patient's clinical history, body measurements, and laboratory test results were obtained. RESULTS: A total of 18 287 patients aged 51 ± 16 years were recruited. Of this group, 67.5% were female, with an average bodyweight of 77.5 ± 16.2 kg and a body mass index 29.7 ± 5.9 kg/m². The prevalence rates of a history of myocardial infarction, stroke, diabetes mellitus, and hypertension were 2.6%, 3%, 13.3%, and 53%, respectively, and the rates of smoking, unhealthy diet, sedentary lifestyle, and psychological stress were 29.3%, 41.2%, 58.2%, and 56.6%. The overall prevalence of obesity and overweight was 79.6%; the rates of prehypertension and systemic hypertension were 39% and 25%, respectively; and the prevalence of metabolic syndrome was 34.7%. CONCLUSIONS: Although the prevalence rates of smoking, systemic hypertension, and diabetes mellitus were low, those for obesity, sedentary lifestyle, psychological stress, unhealthy diet, and metabolic syndrome were very high. This finding demonstrates the need for global action to prevent disability and death from ischemic heart and cerebrovascular disease. It is urgent to implement programs to address these challenges on a national scale.

OBJECTIVE: To determine the initial management and in-hospital mortality of patients with acute coronary syndrome who attended referral hospitals in Paraguay. METHOD: Observational, multicenter study, in patients over 18 years with a confirmed diagnosis of acute coronary syndrome. RESULTS: 780 patients were included from May 2015 to February 2016; the mean age was 64.1 ± 12.3 years, 64.1% male. The clinical presentation was acute coronary syndrome with ST elevation in 40.1% and without elevation in 59.9%. In patients with ST elevation there is a high percentage of late attendance, more than 12 h of evolution in 49.8%; those with less than 12 h of evolution underwent reperfusion in 52.2% of the cases, received fibrinolytics in 36.3% of the cases, and primary percutaneous coronary intervention 15.9%. In-hospital mortality for acute coronary syndrome was 10.3%, with ST-segment elevation was 12.8%, and without ST-segment elevation was 8.6%. CONCLUSIONS: The management of acute coronary syndrome in Paraguay needs a comprehensive approach, which promotes earlier care, and increases the implementation of reperfusion therapies in the health services network, in order to improve the therapeutic response rates and decrease hospital mortality.
OBJETIVO: Determinar el tratamiento inicial y la mortalidad intrahospitalaria de pacientes con síndrome coronario agudo que acudieron a centros hospitalarios de referencia de Paraguay. MÉTODO: Estudio observacional y multicéntrico en pacientes mayores de 18 años con diagnóstico confirmado de síndrome coronario agudo. RESULTADOS: Se incluyó a 780 pacientes desde mayo de 2015 hasta febrero de 2016; la edad media fue de 64.1 ± 12.3 años y el género masculino representó el 64.1%. La presentación clínica fue la de síndrome coronario agudo con elevación del ST en 40.1% y sin elevación del ST en 59.9%. En pacientes con elevación del ST se observó un alto porcentaje de consultas tardías, mayor de 12 h de evolución en 49.8%; en aquéllos con menos de 12 h de evolución se indicó la reperfusión en 52.2%, el 36.3% recibió fibrinolíticos y 15.9% intervención coronaria percutánea primaria. La mortalidad hospitalaria del síndrome coronario agudo fue de 10.3%, con elevación del segmento ST en 12.8% y sin elevación del segmento ST en 8.6%. CONCLUSIONES: El tratamiento del síndrome coronario agudo en el Paraguay requiere un abordaje integral, que promueva consultas más tempranas y aumente la institución de tratamientos de reperfusión en la red de servicios de salud; el objetivo es mejorar los índices de respuesta terapéutica y disminuir la mortalidad hospitalaria.

BACKGROUND: Cardiovascular diseases are the current leading causes of death and disability globally. OBJECTIVE: To assess the effects of a basic educational program for cardiovascular prevention in an unselected outpatient population. METHODS: All participants received an educational program to change to a healthy lifestyle. Assessments were conducted at study enrollment and during follow-up. Symptoms, habits, ATP III parameters for metabolic syndrome, and American Heart Association's 2020 parameters of cardiovascular health were assessed. RESULTS: A total of 15,073 participants aged ≥ 18 years entered the study. Data analysis was conducted in 3,009 patients who completed a second assessment. An improvement in weight (from 76.6 ± 15.3 to 76.4 ± 15.3 kg, p = 0.002), dyspnea on exertion NYHA grade II (from 23.4% to 21.0%) and grade III (from 15.8% to 14.0%) and a decrease in the proportion of current active smokers (from 3.6% to 2.9%, p = 0.002) could be documented. The proportion of patients with levels of triglycerides > 150 mg/dL (from 46.3% to 42.4%, p < 0.001) and LDL cholesterol > 100 mg/dL (from 69.3% to 65.5%, p < 0.001) improved. A ≥ 20% improvement of AHA 2020 metrics at the level graded as poor was found for smoking (-21.1%), diet (-29.8%), and cholesterol level (-23.6%). A large dropout as a surrogate indicator for low patient adherence was documented throughout the first 5 visits, 80% between the first and second assessments, 55.6% between the second and third assessments, 43.6% between the third and fourth assessments, and 38% between the fourth and fifth assessments. CONCLUSION: A simple, basic educational program may improve symptoms and modifiable cardiovascular risk factors, but shows low patient adherence.

Fundamentos: As doenças cardiovasculares são, atualmente, as maiores causas de óbito e incapacitação em todo o mundo. Objetivos: Avaliar os efeitos de um programa educativo básico para prevenção cardiovascular em uma população de pacientes ambulatoriais não selecionados. Métodos: Todos os participantes frequentaram um programa educativo de mudança para um estilo de vida saudável. Foram realizadas avaliações à admissão no estudo e durante o acompanhamento. Foram avaliados sintomas, hábitos, parâmetros do ATP III para síndrome metabólica e parâmetros da American Heart Association 2020 para saúde cardiovascular. Resultados: Foram incluídos no estudo 15.073 participantes com idade ≥ 18 anos. Foi feita a análise de dados dos 3.009 pacientes que completaram a segunda avaliação. Foram documentados perda de peso (de 76,6 ± 15,3 para 76,4 ± 15,3 kg, p = 0,002), melhora da dispneia aos esforços graus II-NYHA (de 23,4% para 21,0%) e III (de 15,8% para 14,0%), e redução na proporção de fumantes ativos atuais (de 3,6% para 2,9%, p = 0,002). Houve melhora na proporção de pacientes com níveis de triglicérides > 150 mg/dL (de 46,3% para 42,4%, p < 0,001) e de colesterol LDL > 100 mg/dL (de 69,3% para 65,5%, p < 0,001). Houve melhora ≥ 20% na métrica AHA 2020 no nível classificado como ruim para tabagismo (-21,1%), alimentação (-29,8%), e nível de colesterol (23,6%). Foi documentada grande evasão como indicador substituto para baixa adesão de paciente nas primeiras 5 consultas, sendo 80% entre a primeira e a segunda avaliação, 55,6% entre a segunda e a terceira, 43,6% entre a terceira e a quarta, e 38% entre a quarta e a quinta. Conclusão: Um programa educativo básico e simples pode melhorar os sintomas e fatores de risco cardiovasculares modificáveis, mas conta com pouca adesão por parte dos pacientes. .
