Resident training to optimize patient-focused menopause management: a multispecialty menopause curriculum to enhance knowledge and preparedness.

OBJECTIVE: Surveys of residents in obstetrics and gynecology, internal medicine, and family medicine have demonstrated low levels of knowledge and comfort in treating patients with menopausal symptoms, suggesting a need for improved training during residency. To address this problem, we used a flipped classroom design to deliver a novel menopause curriculum for medical residents. The curriculum included six podcast episodes followed by an interactive case-based classroom session. We then assessed effects of the curriculum on the residents' knowledge and preparedness to manage menopause symptoms. METHODS: We targeted 200 residents (43 obstetrics and gynecology, 86 internal medicine, and 71 family medicine) from six residency programs from 2019 to 2020. Of these, 115 (58%) completed both pre- and postcurriculum assessments, including a 15-item knowledge test and self-ratings of their knowledge, comfort, and preparedness to manage menopause. RESULTS: Following the curriculum, the proportion of correctly answered knowledge questions rose from 60.8% to 79.1% (+18.3%; 95% confidence interval, 15.4-21.2; Cohen's d = 1.2). Improvement did not significantly differ by specialty or year of residency. There were higher gains for residents who listened to the entirety of all six podcast episodes ( b = 11.4, P < 0.001) and who attended the classroom session ( b = 11.6, P = 0.003). Residents' self-ratings of knowledge, comfort, and preparedness also improved following the curriculum across all medical specialties (Cohen's d = 0.47-1.2). Residents rated the podcast format as convenient (73%) and effective (65%) compared with an equivalent amount of reading. CONCLUSIONS: Pairing a podcast with a classroom discussion was found to be an effective combination for improving menopause knowledge.

Importance of a specialty clinic for individuals with fragile X syndrome.

Advances in human genetics have identified a significant number of genetic disorders associated with intellectual disability. As a result, appropriate clinical management of these affected individuals and their family members have become critical in addressing medical needs to improve quality of life. We examine the importance of a Fragile X Clinic for individuals with fragile X syndrome (FXS) and their family members by conducting a retrospective chart review of 123 new patients with FXS evaluated at the Fragile X Clinic at Emory University. After the initial diagnosis of a proband with FXS with cascade testing, there were 345 family members identified with a mutation (70% with premutations; 30% with full mutations). In terms of the impact of the clinic visit, males had a substantial number of new diagnoses in all behavioral disorders (P < 0.001), with anxiety (62%) being the most common. For female probands, the most frequent diagnosis was also anxiety (87%). Prior to the clinic visit, very few patients were prescribed psychotropic medications. After the clinic visit, the most frequently prescribed psychotropic medications for males were stimulants (41%; P < 0.001) and SSRIs (40%; P < 0.001). For females, only stimulants (33%; P = 0.03) and SSRIs (44%; P = 0.008) were statistically significantly prescribed. Our results revealed that there is a gap in care to address the co-morbid behavioral issues, psychopharmacologic medication management, and genetic counseling needs regarding FXS. A multidisciplinary setting and approach, such as that offered by a Fragile X Clinic, is one method of treating the complex needs of patients with FXS. © 2016 Wiley Periodicals, Inc.

Neurodevelopmental outcomes in children with Down syndrome and infantile spasms.

Down syndrome (DS) is the most common genetic cause of intellectual disability in the United States. The prevalence of seizure in individuals with DS is 1-13%, and infantile spasm (IS) occurs in 6-32% of those with seizures. Since IS is relatively common in children with DS, it is important to understand the impact IS has on the neurodevelopmental outcomes in order to provide appropriate anticipatory guidance to help maximize the potential of these children. Our study is the first to compare the neurodevelopmental outcomes of children with DS and IS (DS + IS) to children with DS and no history of seizures (DS - IS). Using the Bayley Scales of Infant and Toddler Development III, we assessed the neurodevelopment of 29 subjects (eight DS + IS and 21 DS - IS). Neurodevelopmental outcome was poor in the DS + IS cohort, but the delay in treatment does not appear to contribute to any differences in their developmental scores. However, when compared to children with DS - IS, the DS + IS cohort scored approximately 20 points less in all domains including cognitive, motor, and language (P < 0.05). Our results indicate that IS may impact the neurodevelopmental outcomes of children with DS + IS; thus, it is important to provide ongoing developmental and educational assessments and potentially additional therapies for children with DS + IS.

Climbing the branches of a family tree: diagnosis of fragile X syndrome.

OBJECTIVE: To determine the average number of family members diagnosed with a Fragile X Mental Retardation-1 (FMR1) mutation after a proband receives the initial diagnosis of fragile X syndrome (FXS). STUDY DESIGN: We reviewed pedigrees of families who had been evaluated at the Fragile X Syndrome Center at Emory University in Atlanta, Georgia. Through these pedigrees, we determined the number of additional family members diagnosed as FMR1 premutation carriers or with full mutation FXS after the initial diagnosis in each proband. RESULTS: The fragile X pedigree review identified 176 probands, including 108 males (61%) and 68 females (39%). A total of 785 family members were diagnosed with expanded fragile X alleles, including 278 males (35%) and 507 females (65%). These family members included 227 individuals with full mutation FXS (219 males and 8 females) and 558 premutation carriers (59 males and 499 females). After the initial diagnosis of a proband with FXS, on average at least 5 additional family members were diagnosed with an FMR1 mutation. CONCLUSION: Our findings confirm that obtaining a detailed family history after diagnosis of a proband with FXS is likely to identify multiple family members with FMR1 mutations. It is important that the pediatrician or other health care provider making a diagnosis of FXS recognize the value of a detailed family history for timely diagnosis and treatment of additional individuals who may be FMR1 premutation carriers or have full mutation FXS.

A male with cooccurrence of down syndrome and fragile x syndrome.

Down syndrome is the most common identifiable genetic cause of intellectual disability, with a unique physical gestalt that makes diagnosis possible during the newborn period. However, the physical characteristics of Fragile X syndrome are fairly subtle, resulting in the first clinical suspicion often arising from delayed developmental milestones. In addition, maladaptive behavior and autistic-like tendencies, such as hand flapping, poor eye contact, and hand biting, may be noted in Fragile X syndrome but are not as commonly observed in Down syndrome. Recognition of a potential secondary diagnosis, such as Fragile X syndrome, in individuals with Down syndrome is critical because there have been advances in targeted pharmacologic treatments for both conditions. Thus, an accurate diagnosis has implications in improving the individual's quality of life.

Genetic architecture of skin and eye color in an African-European admixed population.

Variation in human skin and eye color is substantial and especially apparent in admixed populations, yet the underlying genetic architecture is poorly understood because most genome-wide studies are based on individuals of European ancestry. We study pigmentary variation in 699 individuals from Cape Verde, where extensive West African/European admixture has given rise to a broad range in trait values and genomic ancestry proportions. We develop and apply a new approach for measuring eye color, and identify two major loci (HERC2[OCA2] P = 2.3 × 10(-62), SLC24A5 P = 9.6 × 10(-9)) that account for both blue versus brown eye color and varying intensities of brown eye color. We identify four major loci (SLC24A5 P = 5.4 × 10(-27), TYR P = 1.1 × 10(-9), APBA2[OCA2] P = 1.5 × 10(-8), SLC45A2 P = 6 × 10(-9)) for skin color that together account for 35% of the total variance, but the genetic component with the largest effect (~44%) is average genomic ancestry. Our results suggest that adjacent cis-acting regulatory loci for OCA2 explain the relationship between skin and eye color, and point to an underlying genetic architecture in which several genes of moderate effect act together with many genes of small effect to explain ~70% of the estimated heritability.

Molecular and evolutionary history of melanism in North American gray wolves.

Morphological diversity within closely related species is an essential aspect of evolution and adaptation. Mutations in the Melanocortin 1 receptor (Mc1r) gene contribute to pigmentary diversity in natural populations of fish, birds, and many mammals. However, melanism in the gray wolf, Canis lupus, is caused by a different melanocortin pathway component, the K locus, that encodes a beta-defensin protein that acts as an alternative ligand for Mc1r. We show that the melanistic K locus mutation in North American wolves derives from past hybridization with domestic dogs, has risen to high frequency in forested habitats, and exhibits a molecular signature of positive selection. The same mutation also causes melanism in the coyote, Canis latrans, and in Italian gray wolves, and hence our results demonstrate how traits selected in domesticated species can influence the morphological diversity of their wild relatives.
