- Rare coding variants in TREM2, PLCG2, and ABI3 were recently associated with the susceptibility to Alzheimer’s disease (AD) in Caucasians. Frequencies and AD-associated effects of variants differ across ethnicities. To start filling the gap on AD genetics in South America and assess the impact of these variants across ethnicity, we studied these variants in Argentinian population in association with ancestry. TREM2 (rs143332484 and rs75932628), PLCG2 (rs72824905), and ABI3 (rs616338) were genotyped in 419 AD cases and 486 controls. Meta-analysis with European population was performed. Ancestry was estimated from genome-wide genotyping results. All variants show similar frequencies and odds ratios to those previously reported. Their association with AD reach statistical significance by meta-analysis. Although the Argentinian population is an admixture, variant carriers presented mainly Caucasian ancestry. Rare coding variants in TREM2, PLCG2, and ABI3 also modulate susceptibility to AD in populations from Argentina, and they may have a European heritage.

- Fugl-Meyer Assessment (FMA) is the most widely used and recommended clinical scale for evaluation of sensorimotor impairment post stroke, but an official Spanish version is not available today. This study aimed to establish methodological structure for translation and cultural adaptation process and perform a transcultural validation of the upper and lower extremity FMA to Colombian Spanish.Procedures included forward and backward translation, step-wise reviewing by bilingual and professional experts to ensure conceptual and semantic equivalence. Validation included a pilot evaluation of item-level agreement on 10 individuals with stroke at the Central Military Hospital of Colombia.Comprehensive step-wise procedure for transcultural validation was established. Low agreement (less than 70%) was detected for items assessing arm movements within synergies and for coordination/speed subscale. All points of disagreement were systematically reviewed and agreed upon when drafting the final version of the Spanish FMA.Use of FMA will allow unified description of stroke severity and motor recovery in Spanish speaking countries. This will open up possibility to compare stroke and rehabilitation outcomes with other countries and regions world-wide. Comprehensive methodological procedures provided can facilitate introduction of well-established clinical scales in other languages. Implications for Rehabilitation The Fugl-Meyer Assessment (FMA) of upper and lower extremity is the most used and recommended clinical scale for evaluation of sensorimotor impairment after stroke. The Spanish version of FMA, validated in this study, is now first time available for use in research and clinical practice. Use of FMA will allow unified description of stroke severity and motor recovery in Spanish speaking countries, which in turn opens up possibility to compare stroke and rehabilitation outcomes with other countries and regions world-wide.

- Objective: The Fugl-Meyer Assessment of Upper Extremity (FMA-UE) is recommended for evaluation of sensorimotor impairment post stroke, but the item-level reliability of the scale is unknown. This study aims to determine intra- and inter-rater reliability of the FMA-UE at item-, subscale- and total score level in patients with early subacute stroke. Design: Intra/inter-rater reliability. Subjects: Sixty consecutively included patients with stroke (mean age 65.9 years) admitted to Central Military Hospital of Colombia, Bogota. Methods: Two physiotherapists scored FMA-UE independently on 2 consecutive days within 10 days post stroke. A rank-based statistical method for paired ordinal data was used to assess the level of agreement, systematic and random disagreements. Results: Systematic disagreements either in position or concentration were detected in 4 items of the shoulder section. The item level intra- and inter-rater agreement was high (79-100%). The 70% agreement was also reached for the subscales and the total score when 1-3-point difference was accepted. Conclusion: The FMA-UE is reliable both within and between raters in patients with stroke in the early subacute phase. A wider international use of FMA-UE will allow comparison of stroke recovery between regions and countries and thereby potentially improve the quality of care and rehabilitation in persons with stroke worldwide.
