We calculated frequencies and proportions for selected outpatient respiratory assessments (pulmonary function tests [PFTs], forced vital capacity (FVC), inspiratory/expiratory pressure, and polysomnograms) and abnormal test results. We examined frequencies by disease characteristics (FSHD type, ages of onset, non-ambulatory status, scoliosis, lordosis), obesity, and number of health encounters. Of 170 people with FSHD, 20.0% underwent PFTs during 2008-2016. Polysomnograms were infrequent (14.1%). FVC <80% predicted was recorded for 64.7% of people tested; additional respiratory outcomes were rare (<5%). Frequency of evaluations and respiratory insufficiency were higher among those with known risk factors and longer follow-up. We observed low proportions of respiratory testing among all confirmed cases of FSHD, but relatively high proportions of mild respiratory insufficiency among those tested. The higher proportions of testing among people with conditions that increase risk of respiratory complications suggest targeted monitoring. Broad implementation of the FSHD guidelines recommending all individuals receive baseline respiratory evaluation at diagnosis could identify respiratory insufficiency as a complication of FSHD.</div></div>","PeriodicalId":19135,"journal":{"name":"Neuromuscular Disorders","volume":"46 ","pages":"Article 105240"},"PeriodicalIF":2.7,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142695779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MANCOVA, CAT12 3D statistics and Pearson correlations were conducted. DMD patients showed differences in volumes of distinct subcortical structures, left hemisphere cortical thickness, and gyrification in multiple brain areas compared with healthy controls. The daily treated DMD group exhibited differences in subcortical volumes and different patterns of cortical thickness, sulci depth, and gyrification compared to the intermittent treated DMD group. DMD Dp140<sup>+</sup> patients displayed altered gyrification and sulci depth compared to DMD Dp140<sup>-</sup> patients. Finally, we found correlations between neurobehavioral outcomes and brain areas that showed differences in cortical morphology associated with corticosteroid treatment. Both genotype and corticosteroid treatment are associated with variations in subcortical volumes and cortical morphology, albeit in different ways. Corticosteroid treatment appears to have a more profound association with differences in gray matter characteristics of brain regions that are associated with functional outcomes.</div></div>","PeriodicalId":19135,"journal":{"name":"Neuromuscular Disorders","volume":"45 ","pages":"Article 105238"},"PeriodicalIF":2.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142624804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
