Endovascular Treatment of Acute Lower Limb Ischemia Associated with Cocaine Use: A Scoping Review / Vanessa García Gómez ; Muñoz Durán, Julián A. ; Santiago Echeverri Isaza ; José Miguel Hidalgo Oviedo ; Emilio Sanín Pérez ; Sergio Álvarez Vallejo  

Público ISBD Título : Endovascular Treatment of Acute Lower Limb Ischemia Associated with Cocaine Use: A Scoping Review Tipo de documento : documento electrónico Autores : Vanessa García Gómez, Autor ; Muñoz Durán, Julián A., Autor ; Santiago Echeverri Isaza, Autor ; José Miguel Hidalgo Oviedo, Autor ; Emilio Sanín Pérez, Autor ; Sergio Álvarez Vallejo, Autor Fecha de publicación : 2024 Títulos uniformes : Cureus Idioma : Inglés (eng) Palabras clave : acute; cocaine; crack; ischemia; lower limb. Resumen : The endovascular treatment of acute lower limb ischemia associated with cocaine use is an underexplored topic. This scoping review aims to map existing information and point out potential knowledge gaps for future research. We searched databases with a strategy of terms and keywords (Cocaine, Acute, Lower Limb, and Ischemia) for articles related to acute ischemia in the lower limbs and cocaine use. We established eligibility and exclusion criteria and searched without restrictions on language or date of publication. We obtained five case reports published between 2004 and 2015. Most of the patients were men with an average age of 38 years. Treatments were heterogeneous. Most patients showed improvement after surgical thrombectomy. The sample size and variety of interventions limit the generalizability of the results, so it is necessary to do more studies with robust methodologies to standardize treatments and improve the understanding of the condition.

A public resource of baseline data from the Alzheimer's Prevention Initiative Autosomal-Dominant Alzheimer's Disease Trial / Sergio Álvarez Vallejo    

Público ISBD Título : A public resource of baseline data from the Alzheimer's Prevention Initiative Autosomal-Dominant Alzheimer's Disease Trial Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, Fecha de publicación : 2022 Títulos uniformes : Alzheimer's & Dementia Idioma : Inglés (eng) Palabras clave : Alzheimer’s disease  amyloid  antibody  data sharing  magnetic resonance imaging  positron emission tomography  presenilin 1  primary prevention  secondary prevention Resumen : Introduction: The Alzheimer's Prevention Initiative Autosomal-Dominant Alzheimer's Disease (API ADAD) Trial evaluated the anti-oligomeric amyloid beta (Aβ) antibody therapy crenezumab in cognitively unimpaired members of the Colombian presenilin 1 (PSEN1) E280A kindred. We report availability, methods employed to protect confidentiality and anonymity of participants, and process for requesting and accessing baseline data. Methods: We developed mechanisms to share baseline data from the API ADAD Trial in consultation with experts and other groups sharing data from Alzheimer's disease (AD) prevention trials, balancing the need to protect anonymity and trial integrity with making data broadly available to accelerate progress in the field. We pressure-tested deliberate and inadvertent potential threats under specific assumptions, employed a system to suppress or mask both direct and indirect identifying variables, limited and firewalled data managers, and put forth specific principles requisite to receive data. Results: Baseline demographic, PSEN1 E280A and apolipoprotein E genotypes, florbetapir and fluorodeoxyglucose positron emission tomography, magnetic resonance imaging, clinical, and cognitive data can now be requested by interested researchers. Discussion: Baseline data are publicly available; treatment data and biological samples, including baseline and treatment-related blood-based biomarker data will become available in accordance with our original trial agreement and subsequently developed Collaboration for Alzheimer's Prevention principles. Sharing of these data will allow exploration of important questions including the differential effects of initiating an investigational AD prevention therapy both before as well as after measurable Aβ plaque deposition.

Sex differences in cognitive resilience in preclinical autosomal-dominant Alzheimer's disease carriers and non-carriers: Baseline findings from the API ADAD Colombia Trial / Sergio Álvarez Vallejo  

Público ISBD Título : Sex differences in cognitive resilience in preclinical autosomal-dominant Alzheimer's disease carriers and non-carriers: Baseline findings from the API ADAD Colombia Trial Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, Fecha de publicación : 2022 Títulos uniformes : Alzheimer's & Dementia Idioma : Inglés (eng) Palabras clave : Alzheimer's disease  autosomal-dominant Alzheimer's disease  cognition  neurodegeneration  pathology  preclinical  sex differences Resumen : Introduction: Females may have greater susceptibility to Alzheimer's disease (AD)-pathology. We examined the effect of sex on pathology, neurodegeneration, and memory in cognitively-unimpaired Presenilin-1 (PSEN1) E280A mutation carriers and non-carriers. Methods: We analyzed baseline data from 167 mutation carriers and 75 non-carriers (ages 30 to 53) from the Alzheimer's Prevention Initiative Autosomal Dominant AD Trial, including florbetapir- and fludeoxyglucose-PET, MRI based hippocampal volume and cognitive testing. Results: Females exhibited better delayed recall than males, controlling for age, precuneus glucose metabolism, and mutation status, although the effect was not significant among PSEN1 mutation carriers only. APOE ε4 did not modify the effect of sex on AD biomarkers and memory. Discussion: Our findings suggest that, among cognitively-unimpaired individuals at genetic risk for autosomal-dominant AD, females may have greater cognitive resilience to AD pathology and neurodegeneration than males. Further investigation of sex-specific differences in autosomal-dominant AD is key to elucidating mechanisms of AD risk and resilience. Mención de responsabilidad : Clara Vila-Castelar, Pierre N.

Associations between subregional thalamic volume and brain pathology in autosomal dominant Alzheimer's disease / Sergio Álvarez Vallejo ; Martín Ochoa Escudero    

Público ISBD Título : Associations between subregional thalamic volume and brain pathology in autosomal dominant Alzheimer's disease Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, ; Martín Ochoa Escudero, Fecha de publicación : 2021 Títulos uniformes : Brain Communications Idioma : Inglés (eng) Palabras clave : Presenilin-1  thalamus  MRI  PET imaging  preclinical Resumen : Histopathological reports suggest that subregions of the thalamus, which regulates multiple physiological and cognitive processes, are not uniformly affected by Alzheimer’s disease. Despite this, structural neuroimaging studies often consider the thalamus as a single region. Identification of in vivo Alzheimer’s-dependent volumetric changes in thalamic subregions may aid the characterization of early nuclei-specific neurodegeneration in Alzheimer’s disease. Here, we leveraged access to the largest single-mutation cohort of autosomal-dominant Alzheimer’s disease to test whether cross-sectional abnormalities in subregional thalamic volumes are evident in non-demented mutation carriers (n = 31), compared to non-carriers (n = 36), and whether subregional thalamic volume is associated with age, markers of brain pathology, and cognitive performance. Using automatic parcellation we examined the thalamus in six subregions (anterior, lateral, ventral, intralaminar, medial, posterior) and their relation to age and brain pathology (amyloid and tau), as measured by PET imaging. No between-group differences were observed in the volume of the thalamic subregions. In carriers, lower volume in the medial subregion was related to increased cortical amyloid and entorhinal tau burden. These findings suggest that thalamic Alzheimer’s-related volumetric reductions are not uniform even in preclinical and prodromal stages of autosomal-dominant Alzheimer’s disease and therefore, this structure should not be considered as a single, unitary structure in Alzheimer’s disease research.
