Resumen: La Enfermedad de Von Willebrand adquirida (EVW adquirida) es un trastorno hemorrágico adquirido poco frecuente, con características clínicas y de laboratorio similares a la Enfermedad de Von Willebrand congénita. Asociándose con enfermedades hemato-oncológicas, autoinmunes, cardiovasculares y tumores sólidos. Las gammapatías monoclonales constituyen un grupo heterogéneo de trastornos caracterizados por la proliferación de linfocitos B en los últimos estadios madurativos o células plasmáticas que preservan la capacidad de producir una inmunoglobulina (Ig) monoclonal o alguno de sus componentes. Como consecuencia, se produce la aparición de una paraproteína o componente M (CM) en suero y/o orina que estará formado por la misma cadena pesada o ligera, y por regiones variables idénticas. Se presenta el caso de una mujer de 57 años, que se presenta con un síndrome hemorragíparo, alteración de la crasis en su vía intrínseca, donde se diagnostica EVW adq secundaria a Mieloma Múltiple (MM) con CM IgM 5,9 g/dl. El tratamiento tuvo como objetivos detener el sangrado, prevenir complicaciones y abordar precozmente la patología hemato-oncológica causante. Para su abordaje requirió la realización de recambios plasmáticos terapéuticos (RPT) que tuvieron un rol de acción terapéutica temprana y eficaz con excelente tolerancia. Ante el diagnóstico se inició rápidamente poliquimioterapia siendo ésta una paciente candidata a trasplante de progenitores hematopoyéticos. El objetivo de la presentación de este caso clínico es destacar la importancia de un correcto y oportuno diagnóstico ante la sospecha clínica de una coagulopatía secundaria a una enfermedad hemato-oncológica subyacente. Por lo que hacemos énfasis en el abordaje multidisciplinario.

Resumo: A doença de von Willebrand adquirida (EVW acq, AVWS) é um distúrbio hemorrágico adquirido raro com características clínicas e laboratoriais semelhantes à doença de von Willebrand congênita. Associado a doenças hemato-oncológicas, autoimunes, cardiovasculares e tumores sólidos. As gamopatias monoclonais constituem um grupo heterogêneo de distúrbios caracterizados pela proliferação de linfócitos B nos últimos estágios de maturação ou plasmócitos que preservam a capacidade de produzir uma imunoglobulina monoclonal (Ig) ou um de seus componentes. Como consequência, ocorre o aparecimento de uma paraproteína ou componente M (CM) no soro e/ou na urina, que serão formados pela mesma cadeia pesada ou leve, e por regiões variáveis idênticas. Apresentamos o caso de uma mulher de 57 anos, que apresentava um síndroma hemorrágico, alteração da crase na sua via intrínseca, onde é diagnosticada Doença de Von Willebrand Adquirida secundária a Mieloma Múltiplo. O tratamento visava estancar o sangramento, prevenir complicações e abordar prontamente a patologia hemato-oncológica subjacente. Para sua abordagem, exigiu a realização de plasmaférese terapêutica que teve papel de ação terapêutica precoce e efetiva com excelente tolerância. Diante do diagnóstico, rapidamente foi iniciada poliquimioterapia, sendo este paciente candidato a transplante de células-tronco hematopoiéticas. O objetivo da apresentação deste caso clínico é realçar a importância de um diagnóstico correto e atempado face à suspeita clínica de uma coagulopatia secundária a uma doença hemato-oncológica subjacente. Portanto, enfatizamos a abordagem multidisciplinar.

Abstract: Acquired von Willebrand disease (AVWS) is a rare acquired bleeding disorder with clinical and laboratory features similar to congenital von Willebrand disease. Associated with hemato-oncological, autoimmune, cardiovascular diseases and solid tumors. Monoclonal gammopathies constitute a heterogeneous group of disorders characterized by the proliferation of B lymphocytes in the last stages of maturation or plasma cells that preserve the capacity to produce a monoclonal immunoglobulin (Ig) or one of its components. As a consequence, the appearance of a paraprotein or M component (CM) occurs in serum and/or urine, which will be formed by the same heavy or light chain, and by identical variable regions. We present the case of a 57-year-old woman, who presented with a hemorrhagic parous syndrome, alteration of the crasis in its intrinsic way, where Acquired Von Willebrand Disease secondary to Multiple Myeloma is diagnosed. Treatment was aimed at stopping the bleeding, preventing complications, and promptly addressing the underlying hemato-oncological pathology. For its approach, it required the performance of therapeutic plasma exchanges that had a role of early and effective therapeutic action with excellent tolerance. Given the diagnosis, polychemotherapy was quickly started, this patient being a candidate for hematopoietic stem cell transplantation. The objective of presenting this clinical case is to highlight the importance of a correct and timely diagnosis in the face of clinical suspicion of a coagulopathy secondary to an underlying hemato-oncological disease. Therefore, we emphasize the multidisciplinary approach.

Resumen Los trabajadores agrícolas se exponen frecuentemente a los pesticidas, los cuales pueden afectar el sistema cardiovascular. El objetivo de la investigación fue revisar la asociación entre la exposición ocupacional a pesticidas, el desarrollo de enfermedades cardiovasculares y los biomarcadores utilizados en la vigilancia de la salud de los trabajadores. Para ello se realizó una revisión no sistemática de la literatura en tres bases de datos: Pubmed, Embase y Scopus, con ecuaciones de búsqueda elaboradas con los términos “agrochemicals”, “myocardial infarction”, “occupational exposure” y “farmers", y se incluyeron artículos publicados entre 2007 y 2022. Se encontró que los pesticidas causan elevación de las cifras de presión arterial en trabajadores expuestos y en mujeres embarazadas se relaciona con hipertensión gestacional y preeclampsia. Respecto al infarto agudo de miocardio (IAM), el contacto con los pesticidas clorpirifós, coumafós, carbofurano, pendimetalina, trifluralina y acilalanina aumentan el riesgo de IAM en mujeres, y entre los trabajadores masculinos la exposición a dibromuro de etileno, maneb/mancozeb y dimetil-ditiocarbamato de zinc se asoció con mayor mortalidad. La vigilancia epidemiológica se realiza principalmente con la medición de la actividad de la acetilcolinesterasa eritrocitaria (AChE). Se puede concluir que la exposición a pesticidas puede desencadenar enfermedades cardiovasculares agudas y crónicas, como elevación de las cifras de presión arterial, IAM fatal y no fatal. Los pesticidas dimetil ditiocarbamato de zinc, clorpirifós, coumafós, carbofurano, paratión y malatión son las sustancias que tienen mayor relación con el desarrollo de enfermedad cardiovascular.

Abstract Farmworkers are frequently exposed to pesticides, which can affect the cardiovascular system. The objective of the research was to review the association between occupational exposure to pesticides and the development of cardiovascular diseases, and the biomarkers used in monitoring the health of workers. For this, a non-systematic review of the literature was carried out in three databases: Pubmed, Embase and Scopus, with search equations prepared with the terms "agrochemicals", "myocardial infarction", "occupational exposure" and "farmers". Articles published between 2007 and 2022 were included. Pesticides were found to cause elevated blood pressure levels in exposed workers, and in pregnant women it is related to gestational hypertension and preeclampsia. Regarding acute myocardial infarction (AMI), contact the pesticides chlorpyrifos, coumaphos, carbofuran, pendimethalin, trifluralin, and acylalanine increased the risk of AMI in women, and among male workers exposure to ethylene dibromide, maneb/mancozeb, and zinc dimethyldithiocarbamate was associated with increased mortality. Epidemiological surveillance is mainly carried out by measuring erythrocyte acetylcholinesterase (AChE) activity. It can be concluded that exposure to pesticides can trigger acute and chronic cardiovascular diseases, such as elevated blood pressure, fatal and non-fatal AMI. Zinc dimethyl dithiocarbamate, chlorpyrifos, coumafos, carbofuran, parathion and malathion pesticides are the substances most closely related to the development of cardiovascular disease.

Resumo: Introdução: A hipertensão arterial (HA) é a principal causa de morte por doenças cardiovasculares. Apesar dos avanços, o percentual de hipertensos não diagnosticados e não tratados é de 58,4%. A avaliação do dano cognitivo na hipertensão concentra-se na prevenção do acidente vascular cerebral, enquanto o dano funcional é ignorado. Esse manejo inadequado pode ser multifatorial. É objetivo fue analisar a opinião dos médicos sobre a relação entre hipertensão arterial e danos cognitivos. Metodologia: Estudo observacional, descritivo, transversal desenvolvido no período entre agosto de 2020 e agosto de 2023. Análise de dados obtidos a partir de questionário autoaplicável, anônimo e voluntário. Revelar informações sobre o perfil profissional, conhecimento sobre a HA, sua ligação com o comprometimento cognitivo (DC), diagnóstico e tratamento. Resultados: Foram incluídos 222 profissionais, 215 (96,8%) concordam com a existência de ligação entre hipertensão e outros fatores de risco cardiovascular na DC e 218 (98,1%) reconhecem ajudar pacientes com risco de sofrer de D.C. A avaliação da DC é realizada em casos selecionados por 132 (59,4%) participantes e 59 (26,7%) a fazem sempre. Dos que realizam avaliação, 103 (54%) utilizam o Mini Exame do Estado Mental (MEEM), 10 (5,2%) utilizam a Avaliação Cognitiva de Montreal (MoCA) e 9 (4,7%) utilizam o Clock Drawing Test. Em relação à diminuição da pressão arterial em pacientes idosos e a ligação com o risco de DC: 54 (24,3%) não reconhecem risco e 65 (29,2%) reconhecem risco moderado-alto. Em referência à implicação do tratamento de doenças cardiovasculares e DC: 217 (97,7%) reconheceram o efeito benéfico. Discussão: Dado o reconhecimento da ligação entre hipertensão e DC, seria de esperar que a DC fosse investigada na grande maioria, no entanto apenas 26,7% sempre a avaliam. Não há consenso sobre o método, sendo o MEEM o mais utilizado, com baixa aplicação do teste MoCA e/ou Clock Drawing Test, sendo estes últimos os que avaliam a função executiva, majoritariamente alterada nos DC vinculados à HA. Embora o tratamento das doenças cardiovasculares seja reconhecido como benéfico em relação à DC, o controle da HA em idosos é considerado arriscado. É feito um diagnóstico de uma situação em que é evidente uma disparidade entre o que se reconhece como saber e o que se afirma fazer. Conclusões: O papel da doença vascular no dano cerebral funcional é reconhecido, considerando-se necessário conhecer o estado cognitivo dos pacientes, porém há baixa aplicação de testes de triagem que avaliam a função executiva. Nesse contexto, evidencia-se uma lacuna entre o conhecimento e a prática médica.

Abstract: Introduction: High blood pressure (HBP) is the leading cause of death from cardiovascular disease. Despite the advances, the percentage of undiagnosed and untreated hypertensive patients is 58.4%. The evaluation of cognitive damage in HBP focuses on preventing stroke, while functional damage is ignored. This inadequate management may be multifactorial. The objective was to analyze the opinions that doctors have about the relationship between high blood pressure and cognitive damage. Methodology: Observational, descriptive, cross-sectional study developed in the period between August 2020 and August 2023. Analysis of data obtained from a self-administered, anonymous and voluntary questionnaire. Revealing information on the professional profile, knowledge of HBP, its link with cognitive impairment (CD), diagnosis and treatment. Results: 222 professionals were included, 215 (96.8%) agree with the existence of a link between HBP and other cardiovascular risk factors in CD, and 218 (98.1%) acknowledge assisting patients at risk of suffering from CD. The CD evaluation is carried out in selected cases by 132 (59.4%) participants and 59 (26.7%) always do it. Of those who perform evaluation, 103 (54%) use the Mini Mental State Examination (MMSE), 10 (5.2%) use the Montreal Cognitive Assessment (MoCA) and 9 (4.7%) use the Clock Drawing Test. Regarding the decrease in blood pressure in elderly patients and the link with risk of CD: 54 (24.3%) do not recognize risk and 65 (29.2%) recognize a moderate-high risk. In reference to the implication of the treatment of cardiovascular disease and CD: 217 (97.7%) recognized a beneficial effect. Discussion: Given the recognition of the link between HBP and CD, it would be expected that CD would be investigated in the vast majority, however only 26.7% always evaluate it. There is no consensus on the method, the MMSE being the most used, with a low application of the MoCA test and/or Clock Drawing Test, the latter being the ones that evaluate executive function, mostly altered in CD linked to HBP. Although the treatment of cardiovascular disease is recognized as beneficial with respect to CD, the control of HBP in older adults is considered risky. A diagnosis is made of a situation where a disparity is evident between what one recognizes as knowing and what one claims to do. Conclusions: The role of vascular disease in functional brain damage is recognized, considering it necessary to know the cognitive status of patients, however there is a low application of screening tests that evaluate executive function. In this context, a gap between medical knowledge and practice is shown.

ABSTRACT Introduction: Arterial hypertension is a public health problem that mainly affects the adult population, which, together with low therapeutic adherence, limits the control of the pathology and achievement of therapeutic objectives. Objective: To determine the prevalence of therapeutic adherence in people with arterial hypertension and the relationship with behavioral and metabolic risk factors in primary health care in the city of Neiva, Colombia. Materials and methods: Cross-sectional analytical study with a sample of 335 randomly selected hypertensive adults attending a cardiovascular risk program. Behavioral and metabolic risk factors, anthropometric and clinical measurements, and the level of therapeutic adherence were evaluated. Stata 15 was used for statistical analysis, applying measures of central tendency and association. Results: Therapeutic adherence was 39.4% and a statistically significant association was found with adulthood (OR: 2.46; 95% CI: 1.49 - 4.05), education (OR: 3.14; 95% CI: 1 .82 - 5.42), taking 3 or fewer medications (OR: 2.09; 95% CI: 1.27 - 3.43) and with therapeutic objectives such as normal BM1, normotension and normoglycemia. Conclusions: The prevalence of therapeutic adherence was low, similar to that evidenced in other contexts of patients with chronic pathologies, associated with behavioral and metabolic factors.

SUMMARY: Studies have shown an association between homocysteine (Hcy) and several pathological conditions, including cardiovascular disease. However, the relationship between Hcy and testicular disorders is still unclear. The present study investigated the effects of Hcy on testicular structure. Thirteen adult Wistar albino rats were divided into two groups. The control group and the methionine group received an oral solution of L-methionine 200 mg /kg per day for six months. Blood samples and testes were collected for subsequent experiments. Serum levels of Hcy and testosterone were analyzed. We examined the histopathological and immunohistochemical localization of GATA-4, vimentin (VIM), connexin-43 (Cx-43), occludin (OCLN), androgen receptor (AR), estrogen receptor 1 (ESR1), estrogen receptor 2 (ESR2) in the rat testis. Results showed that rats receiving methionine showed a reduction in body and testicular weights. Histological and immunohistochemical examination of the testicular tissues of methionine group showed altered structure of seminiferous tubules with decreased immunoexpression of Cx-43, GATA-4, OCLN, VIM, AR, ESR1 and ESR2 compared to control. The results suggest that Hcy has a negative effect on the testes with a probable disruption of spermatogenesis.

RESUMEN: Estudios han demostrado una asociación entre la homocisteína (Hcy) y varias afecciones patológicas, incluidas las enfermedades cardiovasculares. Sin embargo, la relación entre Hcy y los trastornos testiculares aún no está clara. El presente estudio investigó los efectos de la Hcy sobre la estructura testicular. En este trabajo se dividieron trece ratas albinas Wistar adultas en dos grupos. El grupo de control y el grupo de metionina recibieron una solución oral de L-metionina 200 mg/kg por día durante seis meses. Se recogieron muestras de sangre y testículos para experimentos posteriores. Se analizaron los niveles séricos de Hcy y testosterona. Examinamos la localización histopatológica e inmunohistoquímica de GATA-4, vimentina (VIM), conexina-43 (Cx-43), ocludina (OCLN), receptor de andrógenos (AR), receptor de estrógeno 1 (ESR1) y receptor de estrógeno 2 (ESR2) en el testículo de la rata. Los resultados mostraron que las ratas que recibieron metionina presentaron una reducción en el peso corporal y testicular. El examen histológico e inmunohistoquímico de los tejidos testiculares del grupo de metionina mostró una estructura alterada de los túbulos seminíferos con una inmunoexpresión disminuida de Cx-43, GATA-4, OCLN, VIM, AR, ESR1 y ESR2 en comparación con el control. Los resultados sugieren que la Hcy tiene un efecto negativo sobre los testículos con una probable alteración de la espermatogénesis.

SUMMARY OBJECTIVE: The aim of this study was to demonstrate the effect of coronavirus disease 2019 on the cardiovascular autonomic system using heart rate variability in young individuals. METHODS: The study was designed retrospectively by scanning the 24-h Holter electrocardiography records of patients who applied to the Ankara Abdurrahman Yurtaslan Oncology Education and Research Hospital Cardiology outpatient clinic. The study group consisted of 492 patients under the age of 40 years, who did not have additional comorbidities or medication use and had prolonged symptoms after coronavirus disease 2019 during the pandemic. The control group, including 401 patients, was determined during the pre-pandemic period (before December 2019). Heart rate variability parameters were evaluated by scanning the 24-h Holter electrocardiography records of the patients and compared with the non-coronavirus disease 2019 group. RESULTS: The median age of participants was 30 years. Standard deviation of normal RR intervals (SDNN) ≤100 ms was more prevalent in the study group (27 (6.7%) vs 73 (14.8%), p<0.001). In univariate logistic regression analysis, the presence of coronavirus disease 2019 [(OR 2.41, 95%CI 1.52–3.83), p<0.001] and age [(OR 1.04, 95%CI 1.01–1.07), p=0.016] had a significant effect on the probability of SDNN≤100. In multivariate logistic regression analysis, the presence of coronavirus disease 2019 [(OR 2.42, 95%CI 1.52–3.85), p<0.001] and age [(OR 2.42, 95%CI 1.52–3.85), p=0.016] had a significant effect on the probability of SDNN≤100. Frequency domain measures such as, high-frequency values were significantly higher in the study group (p=0.029). The study group’s low-frequency/high frequency ratio was significantly lower (p=0.019). The low-frequency/high-frequency ratio’s cut-off value was ≤2.77. for determining the differentiation between coronavirus disease 2019 positive and negative cases in the receiver operating characteristic analysis. The sensitivity rate was 80.7%. The area under the curve value is 0.546 (p=0.019). CONCLUSION: This study showed that coronavirus disease 2019 causes reduced heart rate variability and increased parasympathetic activity in young patients. This may explain the prolonged symptoms after coronavirus disease 2019 infection.

Introduction: Patients with end-stage renal disease (ESRD) frequently change renal replacement (RRT) therapy modality due to medical or social reasons. We aimed to evaluate the outcomes of patients under peritoneal dialysis (PD) according to the preceding RRT modality. Methods: We conducted a retrospective observational single-center study in prevalent PD patients from January 1, 2010, to December 31, 2017, who were followed for 60 months or until they dropped out of PD. Patients were divided into three groups according to the preceding RRT: prior hemodialysis (HD), failed kidney transplant (KT), and PD-first. Results: Among 152 patients, 115 were PD-first, 22 transitioned from HD, and 15 from a failing KT. There was a tendency for ultrafiltration failure to occur more in patients transitioning from HD (27.3% vs. 9.6% vs. 6.7%, p = 0.07). Residual renal function was better preserved in the group with no prior RRT (p < 0.001). A tendency towards a higher annual rate of peritonitis was observed in the prior KT group (0.70 peritonitis/year per patient vs. 0.10 vs. 0.21, p = 0.065). Thirteen patients (8.6%) had a major cardiovascular event, 5 of those had been transferred from a failing KT (p = 0.004). There were no differences between PD-first, prior KT, and prior HD in terms of death and technique survival (p = 0.195 and p = 0.917, respectively) and PD efficacy was adequate in all groups. Conclusions: PD is a suitable option for ESRD patients regardless of the previous RRT and should be offered to patients according to their clinical and social status and preferences.

Introdução: Pacientes com doença renal em estágio terminal (DRET) frequentemente mudam de modalidade de terapia renal substitutiva (TRS) por razões médicas ou sociais. Nosso objetivo foi avaliar desfechos de pacientes em diálise peritoneal (DP) segundo a modalidade anterior de TRS. Métodos: Realizamos estudo retrospectivo observacional unicêntrico, em pacientes prevalentes em DP, de 1º de janeiro de 2010 a 31 de dezembro de 2017, acompanhados por 60 meses ou até saírem de DP. Pacientes foram divididos em três grupos de acordo com a TRS anterior: hemodiálise prévia (HD), transplante renal malsucedido (TR) e DP como primeira opção (PD-first). Resultados: Entre 152 pacientes, 115 eram PD-first, 22 transitaram da HD e 15 de TR malsucedido. Houve tendência à maior ocorrência de falência de ultrafiltração em pacientes em transição da HD (27,3% vs. 9,6% vs. 6,7%; p = 0,07). A função renal residual foi melhor preservada no grupo sem TRS prévia (p < 0,001). Observou-se tendência à maior taxa anual de peritonite no grupo TR prévio (0,70 peritonite/ano por paciente vs. 0,10 vs. 0,21; p = 0,065). Treze pacientes (8,6%) tiveram um evento cardiovascular maior, cinco dos quais haviam sido transferidos de um TR malsucedido (p = 0,004). Não houve diferenças entre PD-first, TR prévio e HD prévia em termos de óbito e sobrevida da técnica (p = 0,195 e p = 0,917, respectivamente) e a eficácia da DP foi adequada em todos os grupos.

ABSTRACT Background: In the diagnosis and follow-up of arterial hypertension (HTN) most practice guidelines recommend ambulatory blood pressure monitoring (ABPM). In this regard, there is increasing evidence supporting the superiority of nocturnal hy pertension (NHTN) as a predictor of cardiovascular events. Little is known about the relationship with cardiovascular events according to the severity of NHTN. Furthermore, it is unclear from what nighttime pressure value the risk begins to increase. Objectives: The aim of this study was to determine whether the presence of NHTN and its severity levels are associated with adverse cardiovascular outcomes during follow-up. Methods: An observational study was performed analyzing data collected from 24-hour ABPM studies obtained in a high complexity medical center in Buenos Aires. We examined patients’ clinical characteristics, laboratory findings, imaging studies and their results during the follow-up period. Our study included ≥18 year-old persons who had been diagnosed with hypertension. We defined NHTN as those cases with blood pressure values ≥120/70 mmHg during the nighttime period. Results: The final analysis included 981 patients. Among these, 53% were men, mean age was 59.4 years and NHTN was present in 63.6% of cases (n=624). Nocturnal HTN was classified into four severity strata for comparison, according to the nighttime systolic blood pressure value: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg and 160-220 mmHg. Major adverse cardiovascular events were recorded in 8 (2.2%), 17 (4.1 %), 8 (5.6%) and 7 (11.3%) subjects, respectively, and this differ ence between groups was statistically significant (p=0.007). Multivariate Cox regression analysis showed that the presence of NHTN was an independent predictor of adverse cardiovascular events (HR 3.60; 95% CI 1.12-11.5; p=0.033), even when considering the presence of daytime hypertension. Conclusion: In this contemporary cohort, NHTN and its severity were independently associated with the incidence of adverse cardiovascular events.

RESUMEN Introducción: En el diagnóstico y seguimiento de la hipertensión arterial (HTA) la mayoría de las guías de práctica recomiendan el monitoreo ambulatorio de la presión arterial (MAPA). En este sentido, existe cada vez más evidencia que respalda la superioridad de la hipertensión arterial nocturna (HTAN) como predictor de eventos cardiovasculares. Se sabe poco sobre la relación con los eventos cardiovasculares según la gravedad de la HTAN. Además, no está claro a partir de qué valor de presión arterial nocturna comienza a aumentar el riesgo. Objetivos: Conocer si la presencia de HTAN y sus niveles de gravedad se asocian con resultados cardiovasculares adversos durante el seguimiento. Material y métodos: Estudio observacional. Realizamos un análisis de los datos obtenidos en un centro médico de alta complejidad de Buenos Aires, recopilados a partir de estudios de MAPA de 24 horas. Examinamos las características clínicas de los pacientes, los resultados de laboratorio, los estudios de imagen y sus resultados durante el período de seguimiento. Nuestro estudio incluyó personas de 18 años o más a las que se les había diagnosticado hipertensión. Definimos HTAN como aquellos casos con valores de presión arterial ≥ 120/70 mmHg durante el periodo nocturno. Resultados: Fueron incluidos 981 pacientes en el análisis final. De ellos, el 53 % eran hombres; la edad media era de 59,4 años. Presentaban HTAN 63,6 % (n=624). Clasificamos la HTAN en cuatro estratos de gravedad para comparar, según el valor de presión arterial sistólica nocturna: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg y 160-220 mmHg. Se registraron eventos adversos cardiovasculares mayores en 8 (2,2 %), 17 (4,1 %), 8 (5,6 %) y 7 (11,3 %) sujetos, respectivamente, y esta diferencia entre grupos fue estadísticamente significativa (p=0,007). El análisis multivariado de regresión de Cox demostró que la presencia de HTAN fue un predictor independiente de eventos cardiovasculares adversos (HR 3,60; IC 95% 1,12-11,5; p=0,033), incluso al considerar la presencia de hipertensión arterial diurna. Conclusión: En esta cohorte contemporánea, la HTAN y su gravedad se asociaron independientemente con la incidencia de eventos cardiovasculares adversos.

Nos últimos anos, evidências do Registro Brasileiro de Biópsia óssea (REBRABO) apontaram uma alta incidência de intoxicação por alumínio (Al) no tecido ósseo de pacientes com DRC em diálise. Essa surpreendente informação parece representar não apenas um acúmulo passivo deste metal, visto que dados prospectivos do REBRABO sugerem que a presença de Al no tecido ósseo pode estar independentemente relacionada a eventos cardiovasculares adversos maiores. Essas informações contrastam com a percepção mundial do controle epidemiológico dessa condição. Neste artigo de opinião, discutimos por que o diagnóstico de acúmulo ósseo de Al não é relatado em outras partes do mundo, e também discutimos uma gama de possibilidades para entender por que nós acreditamos que o acúmulo de Al no tecido ósseo ainda ocorre, não como se apresentava no passado, ou seja, como uma síndrome com sinais e sintomas sistêmicos de intoxicação. anos (REBRABO (Al diálise metal maiores condição opinião mundo ocorre passado seja

In the last few years, evidence from the Brazilian Registry of Bone Biopsy (REBRABO) has pointed out a high incidence of aluminum (Al) accumulation in the bones of patients with CKD under dialysis. This surprising finding does not appear to be merely a passive metal accumulation, as prospective data from REBRABO suggest that the presence of Al in bone may be independently associated with major adverse cardiovascular events. This information contrasts with the perception of epidemiologic control of this condition around the world. In this opinion paper, we discussed why the diagnosis of Al accumulation in bone is not reported in other parts of the world. We also discuss a range of possibilities to understand why bone Al accumulation still occurs, not as a classical syndrome with systemic signs of intoxication, as occurred it has in the past. years (REBRABO (Al dialysis events world paper occurs intoxication past

ABSTRACT This study aimed to determine the level of knowledge about cardiovascular diseases in people in a primary healthcare center (PHCC). A descriptive and cross-sectional study was carried out by surveying people who attended a PHCC in Lima, Peru. A score less than 6 was considered inadequate knowledge. A total of 400 people were surveyed, 66.3% were women and the mean age was 46.8 ± 16.2 years. The average score was 4.52 +/- 1.85. We found that 71% of those surveyed had an inadequate level of knowledge, regardless of age, gender or education level. Our findings show that the level of knowledge about risk factors and cardiovascular disease was inadequate in the primary care population. It is necessary to achieve proper specific education in cardiovascular risk factors in order to reduce the impact of these diseases.

RESUMEN El objetivo del estudio fue determinar el nivel de conocimiento sobre enfermedades cardiovasculares en personas en un centro de salud del primer nivel de atención en salud (PNAS). Se realizó un estudio descriptivo y transversal mediante una encuesta a personas que asistieron a un establecimiento de salud del PNAS en Lima, Perú. Un puntaje menor a 6 se consideró como conocimiento inadecuado. Se encuestó a 400 personas, 66,3% mujeres, de 46,8 ± 16,2 años. La nota promedio fue de 4,52 +/- 1,85. El 71% de los encuestados tuvo un nivel de conocimiento inadecuado, independientemente de la edad, género o grado de instrucción. Nuestros hallazgos muestran que el nivel de conocimiento sobre los factores de riesgo y la enfermedad cardiovascular resultó inadecuado en la población en atención primaria. Es necesario lograr una educación específica en factores de riesgo cardiovascular, para reducir el impacto de estas enfermedades.

RESUMEN Introducción: La validación de métodos de predicción de riesgo es importante para establecer medidas preventivas adecuadas. Objetivo: Evaluar la validez interna de una escala de mortalidad por afección cardiovascular en ancianos. Métodos: Se efectuó un estudio analítico, observacional, retrospectivo, de tipo caso-control, de 58 pacientes fallecidos (casos) y 134 vivos (controles), pertenecientes a 3 áreas de salud (policlínicos Ramón López Peña, Municipal y 28 de septiembre) del municipio de Santiago de Cuba, durante el 2021. Para realizar la validación de dicha escala se evaluó la capacidad discriminativa y la calibración; la validez de apariencia, criterio y constructo, así como su fiabilidad y consistencia interna. Resultados: La escala diseñada discriminó mejor que la EPICARDIAN en ambos sexos; 68,8 % de los fallecidos del grupo de validación fueron clasificados de alto riesgo. El valor del coeficiente alfa de Cronbach fue de 0,639 y el estandarizado de 0,564. Conclusiones: La escala evaluada calibra adecuadamente al aplicarla en otra población con similar característica a la que le dio origen y discrimina de manera pertinente a las personas clasificadas como alto riesgo de fallecer por una enfermedad cardiovascular aterosclerótica.

ABSTRACT Introduction: The validation of risk prediction methods is important to establish appropriate preventive measures. Objective: To evaluate the internal validity of a mortality scale due to cardiovascular affection in elderly. Methods: An analytic, observational, retrospective and case-control study was carried out, in 58 dead patients (cases) and 134 alive patients (control), belonging to 3 health areas (Ramón López Peña, Municipal and 28 de Septiembre polyclinics) in Santiago de Cuba municipality, during 2021. To validate this scale the discriminative capacity and calibration; appearance, criterion and construct validity were evaluated, as well as its reliability and internal strength. Results: The designed scale discriminated better than the EPICARDIAN scale in both sexes; 68.8 % of the deaths in the validation group were classified as high risk. The value of Cronbach´s alpha coefficient was 0.639 and the standardized one was 0.564. Conclusions: The evaluated scale calibrates appropriately when applied to another population with similar characteristics to the one it gave rise to and it pertinently discriminates against people classified as high risk of dying due to atherosclerotic cardiovascular disease.

Abstract: Lipoprotein (a) (Lp(a)) is a particle similar to low-density lipoprotein (LDL) linked to an Apolipoprotein (a). This gives it atherogenic and prothrombotic properties that make it an independent risk factor, not only for atherosclerotic disease but also for other pathologies such as severe aortic stenosis. Given its high genetic determination and low variability due to environmental factors, it is recommended to measure levels of Lp(a) at least once in a lifetime. We present the case of a patient with an estimated low cardiovascular risk based on traditional risk factors, who developed severe coronary artery disease in the context of elevated Lp(a) levels.

Resumen: La Lipoproteína (a) (Lp(a)) es una partícula similar a la lipoproteína de baja densidad (LDL) pero unida a una Apolipoproteína (a). Ello le confiere propiedades aterogénicas y protrombóticas que la transforman en un factor de riesgo independiente, no solo de enfermedad aterosclerótica sino de otras patologías como la estenosis aórtica severa. Dada su alta determinación genética y menor variabilidad frente a factores ambientales, se recomienda la medición de sus niveles al menos una vez en la vida. Presentamos el caso de una paciente catalogada de bajo riesgo cardiovascular basado en factores de riesgo tradicionales pero que desarrolló enfermedad coronaria severa en el contexto de niveles de Lp(a) elevados.

ABSTRACT Post-transplant diabetes mellitus (PTDM) is a frequent complication after organ transplantation. There are several predisposing factors for this complication, which may be present in the pre-transplant, peri-transplant, or already post-transplant; within these, associated immunosuppressive therapies will be highlighted. The clinical importance of DMPT lies in its impact on cardiovascular disease (CVD) and chronic kidney disease (CKD). In this article, we review traditional interventions and new therapies for managing and treating PTDM.

RESUMEN La diabetes mellitus postrasplante (DMPT) es una complicación que se encuentra de forma frecuente y se sucede al trasplante de órganos. Existen factores predisponentes a esta complicación, son varios y pueden estar presentes en el pretrasplante, peritrasplante o ya en el pos trasplante; dentro de estos, se resaltan las terapias inmunosupresoras asociadas. La importancia clínica de DMPT radica en su impacto para la enfermedad cardiovascular (ECV) y enfermedad renal crónica (ERC). En el presente artículo hacemos una revisión de las intervenciones tradicionales y las nuevas terapias para el manejo y tratamiento de la DMPT.

Resumen Introducción : La enfermedad de Fabry (EF) es una enfermedad de almacenamiento lisosomal ligada al cromosoma X que afecta el metabolismo de glicoes fingolípidos. La mayoría de pacientes EF tienen afec tación cardíaca, manifestada principalmente como hipertrofia ventricular izquierda (HVI), que conduce a muerte prematura secundaria a complicaciones (arritmias, valvulopatías, afectación vascular). El trata miento de reemplazo enzimático (TRE) precoz, iniciado antes del desarrollo de la fibrosis, se relaciona con mejores resultados cardíacos en términos del índice de masa ventricular izquierda (IMVI) y parámetros funcionales. Métodos : Se realizó un estudio retrospectivo obser vacional en que se incluyeron pacientes con EF tratados con agalsidasa alfa por al menos 2 años. Los objetivos primarios fueron: [a] evaluar el cambio anual del IMVI; [b] definir la incidencia global de estabilidad, regresión o progresión del IMVI. Resultados : Se incluyeron 49 pacientes, con segui miento (mediana) de 7 años. El cambio global en el IMVI fue 0.38 g/m2.73/año, sin influencia significativa de HVI basal, sexo, edad de inicio de TRE, fracción de eyección del VI, índice de masa corporal, insuficiencia renal y factores de riesgo cardiovascular clásicos. La TRE a largo plazo con agalsidasa alfa se relacionó con la estabilización del IMVI en el 98% de los pacientes con EF, independientemente de las mismas covariables. Conclusión : Nuestros resultados están en línea con la bibliografía previa de poblaciones comparables y, pro bablemente, representan el primer estudio de este tipo en Argentina. Se destaca la importancia de la estabilidad morfométrica cardíaca como resultado positivo de la TRE.

Abstract Introduction : Fabry disease (FD) is an X-linked ly sosomal storage disorder affecting glycosphingolipid metabolism. Most FD patients have cardiac involvement, mainly manifested as left ventricular hypertrophy (LVH), leading to early death due to complications (arrhyth mias, valvular disease, vascular involvement). Early initiation of enzyme replacement therapy (ERT) before fibrosis development has been associated with better cardiac outcomes in terms of left ventricular mass index (LVMI) and functional parameters. Methods : A retrospective observational study was conducted in patients with FD treated with agalsidase alfa for at least 2 years. The primary objectives were: [a] to assess the annual rate of change in LVMI; [b] to define the overall incidence of stability, regression or progression of LVMI. Results : Forty-nine patients were included in the final analysis, with a median follow-up of 7 years. The overall change in LVMI was 0.38 g/m2.73/year, without significant influence of baseline LVH, gender, age at ERT initiation, LV ejection fraction, body mass index, renal disease, and classical cardiovascular risk factors. Long-term ERT with agalsidase alfa was associated with stabilization of LVMI in 98% of patients with FD and was independent of the same covariables. Conclusion : Our results are in line with previous literature of comparable FD populations and probably represent the first study of its kind in Argentina. We here highlight the importance of cardiac morphomet ric stability as a positive outcome of ERT.

Resumo A doença cardiovascular é a causa predominante de mortalidade em escala global. A pesquisa indica que as mulheres, em comparação aos homens, apresentam maior probabilidade de apresentar doença arterial coronariana (DAC) não obstrutiva quando têm sintomas de isquemia miocárdica. Além disso, as mulheres tendem a apresentar uma maior carga de sintomas em relação aos homens e, apesar da presença de doença cardíaca isquêmica, são frequentemente tranquilizadas erroneamente devido à ausência de DAC obstrutiva. Nos casos de cardiopatia isquêmica acompanhada de sintomas de isquemia miocárdica, mas sem DAC obstrutiva, é imperativo considerar a disfunção microvascular coronariana como uma potencial causa subjacente. A disfunção microvascular coronariana, caracterizada por reserva de fluxo coronariano prejudicada resultante de anormalidades funcionais e/ou estruturais na microcirculação, está associada a desfechos cardiovasculares adversos. Modificações no estilo de vida e o uso de medicamentos antiateroscleróticos e antianginosos podem oferecer benefícios potenciais, embora sejam necessários mais ensaios clínicos para informar estratégias de tratamento. Esta revisão tem como objetivo explorar a prevalência, mecanismos subjacentes, abordagens diagnósticas e intervenções terapêuticas para disfunção microvascular coronariana. global (DAC miocárdica disso subjacente eou ou microcirculação adversos potenciais tratamento prevalência subjacentes

Abstract Cardiovascular disease is the predominant cause of mortality on a global scale. Research indicates that women exhibit a greater likelihood of presenting with non-obstructive coronary artery disease (CAD) when experiencing symptoms of myocardial ischemia in comparison to men. Additionally, women tend to experience a higher burden of symptoms relative to men, and despite the presence of ischemic heart disease, they are frequently reassured erroneously due to the absence of obstructive CAD. In cases of ischemic heart disease accompanied by symptoms of myocardial ischemia but lacking obstructive CAD, it is imperative to consider coronary microvascular dysfunction as a potential underlying cause. Coronary microvascular dysfunction, characterized by impaired coronary flow reserve resulting from functional and/or structural abnormalities in the microcirculation, is linked to adverse cardiovascular outcomes. Lifestyle modifications and the use of anti-atherosclerotic and anti-anginal medications may offer potential benefits, although further clinical trials are necessary to inform treatment strategies. This review aims to explore the prevalence, underlying mechanisms, diagnostic approaches, and therapeutic interventions for coronary microvascular dysfunction. scale nonobstructive non CAD (CAD men Additionally andor or microcirculation outcomes antiatherosclerotic anti atherosclerotic antianginal anginal benefits strategies prevalence mechanisms approaches
