💜 Community Talks: Karina 💜 💥 When diagnosis don't justify all symptoms “Daniel had 4 brain surgeries after his diagnosis of Moyamoya in 2001. He was having blood clots and we were advised to have the revascularization surgery so the brain could get better blood flow. Back then, the neurosurgeon who operated on Daniel said to us that Daniel’s MRI didn’t show a typical Moyamoya image. We had to wait 6-7 years to finally get the diagnosis of Multisystemic Smooth Muscle Dysfunction Syndrome (MSMDS). I felt relief with MSMDS including all of Daniel’s symptoms that Moyamoya couldn’t explain. Daniel was one of the firsts to be diagnosed with MSMDS and at that time not much was known about the disease. But it gave me reassurance that the doctors could now keep a close eye on Daniel and compare the results with other patients they could have so all of us together could gain greater knowledge in this disease.” 🧠 MSMDS or Moyamoya? Patients affected by MSMDS with Moyamoya-like disease present a lack of basal collateral vessels and abnormally straight cerebral vessels. Patients with MSMDS have an increased risk of perioperative stroke and usually suffer issues when anaesthesia or sedation are required in medical procedures. 🙌 Understanding MSMDS MSMDS is an incurable multisystemic disease affecting the brain, blood vessels, heart, aorta, lungs, liver, kidneys, bladder, eyes, and other body parts with smooth muscle cells. There are only 60 diagnosed patients worldwide, mostly children. 💚 The Hope of Gene Therapy Gene therapy research in Boston offers hope for MSMDS patients. With your support, we can bring life-changing treatments to those affected by this ultra-rare disease. https://lnkd.in/edkSR9Cy #ActByAct #MSMDS #GeneTherapy #MSMDSAwarenessDay #PatientStory #RareDiseaseAwareness #Moyamoya #moyamoyadisease #MoyamoyaAwareness #Revascularization #brainsurgery #brainsurgerysurvivor #genetherapy

Cool paper in Developmental Cell: Identifying FUS amyotrophic lateral sclerosis disease signatures in patient dermal fibroblasts https://lnkd.in/eb65z6Xk Amyotrophic lateral sclerosis (ALS) is a rapidly progressing, highly heterogeneous neurodegenerative disease, underscoring the importance of obtaining information to personalize clinical decisions quickly after diagnosis. Here, we investigated whether ALS-relevant signatures can be detected directly from biopsied patient fibroblasts. We profiled familial ALS (fALS) fibroblasts, representing a range of mutations in the fused in sarcoma (FUS) gene and ages of onset. To differentiate FUS fALS and healthy control fibroblasts, machine-learning classifiers were trained separately on high-content imaging and transcriptional profiles. “Molecular ALS phenotype” scores, derived from these classifiers, captured a spectrum from disease to health. Interestingly, these scores negatively correlated with age of onset, identified several pre-symptomatic individuals and sporadic ALS (sALS) patients with FUS-like fibroblasts, and quantified “movement” of FUS fALS and “FUS-like” sALS toward health upon FUS ASO treatment. Taken together, these findings provide evidence that non-neuronal patient fibroblasts can be used for rapid, personalized assessment in ALS.

Fusing data analysis and medical writing in rare diseases, oncology, vaccines and precision medicine for impactful insights 👩🏻🔬
Have you heard about #Elevidys ? In recognition of September as the awareness month for Duchenne muscular dystrophy, I'd like to share some insightful facts about this condition, paying tribute to the patients it affects. Duchenne muscular dystrophy (DMD) is a rare and severe genetic disorder that primarily affects muscle function. It is caused by a mutation in the DMD gene, which leads to the absence or deficiency of a protein called dystrophin. Dystrophin is essential for maintaining the structure and strength of muscle fibers. Key characteristics and facts about Duchenne muscular dystrophy include: 👉 Onset: DMD typically becomes evident in early childhood, often between the ages of 3 and 5. 👉 Symptoms: Common symptoms include progressive muscle weakness, difficulty in walking and standing, loss of motor function, and a tendency to develop muscle contractures. 👉 Muscle Degeneration: Over time, muscle tissue is replaced by fat and connective tissue, leading to muscle wasting and weakness. 👉 Mobility Challenges: Children with DMD often require mobility aids like wheelchairs as the disease progresses. 👉 Respiratory and Cardiac Issues: DMD can also affect the respiratory and cardiac muscles, leading to breathing difficulties and heart problems. DMD is an X-linked recessive genetic disorder, primarily affecting males. Females can be carriers of the mutation but are usually asymptomatic. #ELEVIDYS is a prescription gene therapy used to treat ambulatory children aged 4 through 5 years old with Duchenne muscular dystrophy (DMD) who have a confirmed mutation in the dystrophin gene. Elevidys is a recombinant gene therapy designed to deliver into the body a gene that leads to production of Elevidys micro-dystrophin, a shortened protein (138 kDa, compared to the 427 kDa dystrophin protein of normal muscle cells) that contains selected domains of the dystrophin protein present in normal muscle cells. The product is administered as a single intravenous dose. #DMD #duchennemusculardystrophy #duchenneawareness #genetics #rarediseases #proteins

Reporting Cases of Intermediate #NerveConductionVelocity in Patients with #CharcotMarieTooth Disease Type 1A New research from the Inherited #Neuropathy Consortium (INC): https://lnkd.in/gA-7Z2cd Charcot-Marie-Tooth disease type 1A (CMT1A), the most common form of inherited peripheral neuropathy, is caused by duplication of the PMP22 gene. Individuals with CMT1A experience slow nerve conduction velocity (the speed of electrical impulses moving through nerves). Because most patients have nerve conduction rates below 38 meters per second, genetic testing for PMP22 duplication is not usually recommended for those with higher rates. In this study, researchers report cases of intermediate nerve conduction velocity in two patients with CMT1A. Both individuals had upper limb motor nerve conduction velocities above 38 meters per second. These patients also presented with very mild forms of CMT1A. Authors note that although these cases are very rare, they highlight the importance of testing PMP22 duplication in patients with intermediate conduction velocities.

https://lnkd.in/ekXPQpvj Article title: Acute Panmyelosis with Myelofibrosis: The Serpentine Road to Diagnosis Author(s): Celia Suriu; Andrei Braester; Masad Barhoum Journal: Annals of Bone Marrow Research Journal ISSN: 2692-4684 Abstract: cute Panmyelosis with Myelofibrosis (APMF) is an extremely rare disease. Lack of familiarity with this rare subtype of acute leukemia hinders the diagnosis [1]. It is characterized by an acute, rapidly progressive, fatal clinical course, peripheral blood cytopenias with minimum 20% blast and no detectable splenomegaly. APMF corresponds to less than 1% of the cases of Acute Myeloid Leukemia (AML) [2]. Histologically, APMF is characterized by a heavily fibrotic marrow, an increased number of immature hematopoietic elements (panmyelosis), and dysplastic population of megakaryocytes. The condition should be differentiated from other hematological neoplasms that present with fibrosis such as acute megakaryoblastic leukemia and myelodysplsia (MDS) with myelofibrosis. Dacrocytes are not present. #BoneMarrow #BloodSamples #Hematology #AutoimmuneDiseases #StemCells #Immunology #Transplantation #MinimalInvasiveSurgeryTechniques #TranscriptionFactors #Medication #TropicalTreatments #Metabolism #Mortality #DrugTargeting #DrugSensitivity #Resistance #HabitsAndLifestyle #PrognosticFactors #Pathophysiology #NovelDrugs #CellularTherapy #TranslationalResearch #MesenchymalStemCell #HematopoieticStemCellTransplantation #BoneMarrowTransplantation #BoneMarrowEdema #BoneMarrowCancer #BoneMarrowBarrier

How do macrophages eat so much?? In this elegant paper, out today in Nature, the Ravichandran team describes a fascinating transcriptional pause/release mechanism that enables macrophages to rapidly engulf and consume multiple apoptotic cells to achieve homeostasis. Targeting this mechanism in the many disease states that arise/persist due to faulty macrophage function (such as chronic inflammation, cancer, autoimmune disease, etc) could benefit patients.
