Generalized Anxiety Disorder in Hispanics: Symptom Characteristics and Prediction of Severity
Literature suggests that an increasing number of Hispanic people suffer with GAD, and possible associated problems include high costs for treatment and elevated risk of severe impairment. The current study examined components of anxiety, as measured by currently available assessment instruments in both English and Spanish languages, among bilingual Hispanic individuals with GAD. Participants completed all instruments in both languages. Relations between these self-report measures and clinician-rated GAD severity were also studied. In factor analyses, the Spanish measures yielded two factors, the first of which included all instruments assessing physiological components of anxiety and one content specific measure of worry. The second factor included one worry scale and one trait anxiety scale. The English measures yielded a single factor solution. Regression analyses revealed that for the English measures, the BAI and PSWQ were statistically significant predictors of GAD severity. For the Spanish measures, the BAI was the only statistically significant predictor

Cardiac phenotype in ATP1A3-related syndromes A multicenter cohort study
Objective
To define the risks and consequences of cardiac abnormalities in
ATP1A3-related syndromes.
Methods
Patients meeting clinical diagnostic criteria for rapid-onset
dystonia-parkinsonism (RDP), alternating hemiplegia of childhood (AHC),
and cerebellar ataxia, areflexia, pes cavus, optic atrophy, and
sensorineural hearing loss (CAPOS) with ATP1A3 genetic analysis and at
least 1 cardiac assessment were included. We evaluated the cardiac
phenotype in an Atp1a3 knock-in mouse (Mashl(+/-)) to determine the
sequence of events in seizure-related cardiac death.
Results
Ninety-eight patients with AHC, 9 with RDP, and 3 with CAPOS (63 female,
mean age 17 years) were included. Resting ECG abnormalities were found
in 52 of 87 (60%) with AHC, 2 of 3 (67%) with CAPOS, and 6 of 9 (67%)
with RDP. Serial ECGs showed dynamic changes in 10 of 18 patients with
AHC. The first Holter ECG was abnormal in 24 of 65 (37%) cases with AHC
and RDP with either repolarization or conduction abnormalities.
Echocardiography was normal. Cardiac intervention was required in 3 of
98 (approximate to 3%) patients with AHC. In the mouse model, resting
ECGs showed intracardiac conduction delay; during induced seizures,
heart block or complete sinus arrest led to death.
Conclusions
We found increased prevalence of ECG dynamic abnormalities in all
ATP1A3-related syndromes, with a risk of life-threatening cardiac rhythm
abnormalities equivalent to that in established cardiac channelopathies
(approximate to 3%). Sudden cardiac death due to conduction abnormality
emerged as a seizure-related outcome in murine Atp1a3-related disease.
ATP1A3-related syndromes are cardiac diseases and neurologic diseases.
We provide guidance to identify patients potentially at higher risk of
sudden cardiac death who may benefit from insertion of a pacemaker or
implantable cardioverter-defibrillator
