Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS): Study design and harmonization.

INTRODUCTION: Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS) is the first non-pharmacological multicenter randomized clinical trial (RCT) to prevent cognitive impairment in Latin America (LA). Our aim is to present the study design and discuss the strategies used for multicultural harmonization. METHODS: This 1-year RCT (working on a 1-year extension) investigates the feasibility of a multi-domain lifestyle intervention in LA and the efficacy of the intervention, primarily on cognitive function. An external harmonization process was carried out to follow the FINGER model, and an internal harmonization was performed to ensure this study was feasible and comparable across the 12 participating LA countries. RESULTS: Currently, 1549 participants have been screened, and 815 randomized. Participants are ethnically diverse (56% are Nestizo) and have high cardiovascular risk (39% have metabolic syndrome). DISCUSSION: LatAm-FINGERS overcame a significant challenge to combine the region's diversity into a multi-domain risk reduction intervention feasible across LA while preserving the original FINGER design.

Paraparesia espástica tropical: a propósito de un caso clínico / Tropical spastic paraparesis: report of a case

Se presenta el caso clínico de una paciente con diagnóstico inicial de hipotiroidismo, cuadro que ameritó internación, compensado adecuadamente con levotiroxina. A pesar de existir buena respuesta al tratamiento instaurado, persiste la presencia de sintomatología de compromiso neurológico por lo que se solicita evaluación por dicha especialidad; se encuentran datos sugestivos de un cuadro de paraparesia espástica tropical, enfermedad producida por el HTVLI. El diagnóstico es confirmado mediante examenes de laboratorio. Es tratada con pentoxifilina y vitamina C con respuesta clínica inicial buena, pero posteriormente presenta exacerbación de las manifestaciones neurológicas, como sucede habitualmente en esta patología. nuestro país se encuentra en una regíon endemica de la infección mencionada, y sin embargo el diagnóstico es mas bien esporádico. Se discute en este artículo la epidemiología, las dificultades diagnósticas que planteo este caso en particular y las posibilidades terapéuticas de esta enfermedad neurológica.

We present the case of a female patient who initially was diagnosed with hypothyroidism, and adequately compensated with levotiroxin . In spite of the otherwise successfultreatment, neurological symptoms persisted. The neurological examination showed datasuggestive of tropical spastic paraparesis,a disease caused by HTVL-1.The diagnosis was confirmed by laboratory tests. The patient was treated with pentoxifiline and vitamin C, initially with a good clinical response. Later on, however, exacerbation of the neurological symptoms resulted, as usually happens in this disease. In our country, tropical spastic paraparesis is endemic but only sporadically diagnosed. We review the most relevant aspects of epidemiology, the diagnostic difficulty in this case, and the therapeutic options for this neurological disease.
