Assessing the Benefits and Harms Associated with Early Diagnosis from the Perspective of Parents with Multiple Children Diagnosed with Duchenne Muscular Dystrophy
O Battacharria et al, IJNS, April 15, 2024 (Posted Apr 15, 2024 2PM)

From the abstract: " Duchenne muscular dystrophy (DMD) is a rare neuromuscular disorder diagnosed in childhood. Limited newborn screening in the US often delays diagnosis. With multiple FDA-approved therapies, early diagnosis is crucial for timely treatment but may entail other benefits and harms. Using a community-based survey, we explored how parents of siblings with DMD perceived early diagnosis of one child due to a prior child’s diagnosis. We assessed parents’ viewpoints across domains including diagnostic journey, treatment initiatives, service access, preparedness, parenting, emotional impact, and caregiving experience."

Clinical Effectiveness of Newborn Screening for Spinal Muscular Atrophy: A Nonrandomized Controlled Trial.
Oliver Schwartz et al. JAMA Pediatr 2024 4 (Posted Apr 09, 2024 8AM)

From the abstract: " Is early diagnosis through newborn screening associated with improved outcomes in infants with spinal muscular atrophy compared to those diagnosed after onset of symptoms? In this nonrandomized controlled trial within the SMARTCARE registry, patients identified by newborn screening showed better motor development with disease-modifying treatments than those who were diagnosed after onset of symptoms. These results offer supporting evidence for the benefit of newborn screening for spinal muscular atrophy. "

Susceptibility to Treatment-Resistant Depression Within Families.
Chih-Ming Cheng et al. JAMA Psychiatry 2024 4 (Posted Apr 05, 2024 9AM)

From the abstract: " Is the treatment-resistant depression (TRD) phenotype transmitted within a family? This cohort study found that, compared with control individuals match for birth year, sex, and kinship, first-degree-relatives of individuals with TRD had an increased risk of developing TRD and increased suicide mortality. The findings suggest that a family history of TRD might be a clinically significant risk factor for resistance to antidepressant treatment and increased suicide mortality, indicating that combining or altering therapies for depression might be considered instead of monotherapy at an earlier treatment stage. "

Newborn screening for Duchenne muscular dystrophy: the perspectives of stakeholders.
Charli Ji et al. Lancet Reg Health West Pac 2024 3 101049 (Posted Apr 02, 2024 10AM)

From the abstract: "Participants included 50 caregivers and 26 HCPs (68.5% and 53.1% response rate respectively). Most caregivers (40/50, 80%) perceived net benefits of DMD NBS and highlighted an early diagnosis as actionable knowledge, even with the current paucity of disease modifying therapies. This knowledge was valued to enable access to multidisciplinary supportive care (29/50, 58%), clinical trials (27/50, 54%), psychological support (28/50, 56%), inform reproductive planning (27/50, 54%), and facilitate financial planning based on the future needs of their child (27/50, 54%).
