Amyotrophic lateral sclerosis de Shaw

Amyotrophic lateral sclerosis

Autor Shaw
en Limba Engleză Hardback – 1900

Provocarea majoră în gestionarea Sclerozei Laterale Amiotrofice rezidă în variabilitatea sa clinică extremă, care face ca tratamentele standard să eșueze frecvent. Reținem că volumul Spectrums of Amyotrophic Lateral Sclerosis, editat de Christopher A. Shaw și Jessica R Morrice, propune o schimbare de paradigmă: abordarea SLA ca un spectru de afecțiuni cu etiologii multiple, mai degrabă decât ca o entitate patologică singulară. Această perspectivă clinică și de cercetare este esențială pentru dezvoltarea unor intervenții personalizate și a unor terapii de precizie. Subliniem rigoarea cu care sunt analizate mecanismele moleculare, de la defectele în metabolismul ARN până la agregarea proteinelor și implicarea celulelor gliale, demonstrând natura non-celular-autonomă a bolii. Clinicienii care folosesc Amyotrophic Lateral Sclerosis de Hiroshi Mitsumoto ca referință vor găsi aici o completare necesară privind noile perspective asupra factorilor de risc de mediu și rolul emergent al microbiomului. Structura volumului facilitează o înțelegere progresivă, începând cu heterogenitatea clinică și baza genetică (unde sunt detaliate gene precum SOD1 sau C9orf72) și culminând cu o analiză critică a modelelor animale și a strategiilor terapeutice actuale. În contextul operei editorului, Christopher A. Shaw continuă explorarea sistemului nervos începută în Toward a Theory of Neuroplasticity, aplicând aceleași standarde de analiză a organizării neurobiologice asupra proceselor de neurodegenerare. Stilul este unul clinic și precis, oferind o evaluare onestă a motivelor pentru care multe terapii au eșuat în trecut, oferind totodată repere pentru designul viitoarelor studii clinice.

De ce să citești această carte

Această lucrare este esențială pentru neurologii clinicieni și cercetătorii care doresc să înțeleagă de ce SLA se manifestă atât de diferit de la un pacient la altul. Cititorul câștigă o viziune actualizată asupra geneticii și patogenezei bolii, primind argumente solide pentru o abordare terapeutică nuanțată. Este o resursă indispensabilă pentru rezidenții în neurologie care vor să stăpânească complexitatea diagnosticului și a managementului bolii neuronului motor.

Despre autor

Christopher A. Shaw este profesor în cadrul departamentului de oftalmologie de la University of British Columbia, având o vastă experiență în cercetarea sistemului nervos. Activitatea sa academică este marcată de o abordare multidisciplinară a neuroștiințelor, explorând atât mecanismele fundamentale ale neuroplasticității, cât și patologia bolilor neurodegenerative. Pe lângă activitatea de cercetare, Shaw este cunoscut pentru implicarea sa în dezbateri publice privind utilizarea științei în politici de sănătate, experiență care îi conferă o perspectivă critică și analitică asupra modului în care datele clinice sunt interpretate și aplicate în practica medicală curentă.

Descriere

SPECTRUMS OF AMYOTROPHIC LATERAL SCLEROSIS Discover state-of-the-art research findings on ALS from leading authors and editors in the field
In Spectrums of Amyotrophic Lateral Sclerosis: Heterogeneity, Pathogenesis & Therapeutic Directions, distinguished researchers and editors Dr. Christopher A. Shaw and Jessica R. Morrice deliver a practical and powerful perspective on Amyotrophic Lateral Sclerosis (ALS) as a heterogeneous spectrum of disorders. This increasingly accepted point-of-view allows researchers and medical professionals to develop better targeted interventions and more precise therapies.
In the book, readers will find chapters on a wide variety of critical issues facing ALS researchers and healthcare practitioners treating ALS sufferers, including animal models of ALS, neuronal support cells known to have a pivotal role in ALS, and current challenges in ALS clinical trials, among others. The authors describe pathologic features common to all cases of ALS and why animal models, though crucial, should be interpreted with caution. Finally, multiple genetic and environmental etiologies of the disease are discussed.
Readers will also benefit from the inclusion of:

 

  • A thorough introduction to ALS as a spectrum disease and the implications for models, therapeutic development and clinical trial design
  • Explorations of the genetic basis of ALS, prospective sALS etiologies, and the involvement of microbiome in ALS
  • Discussions of ALS-PDC and environmental risk factors, protein aggregation in ALS, defects in RNA metabolism in ALS, and the non-cell autonomous nature of ALS and the involvement of glial cells
  • Examinations of animal models of ALS and perspectives on previously failed ALS therapeutics and current therapeutic strategies

Perfect for clinical neurologists, healthcare providers and caretakers, clinicians, and researchers studying motor neuron disease, Spectrums of Amyotrophic Lateral Sclerosis: Heterogeneity, Pathogenesis & Therapeutic Directions is also an indispensable resource for the neurodegenerative research community, neurology residents, and graduate-level neuroscience students.
