Project description:BackgroundThe prevalence of Parkinson disease (PD) varies by geographic location and ethnicity, but has never been studied among the Navajo.MethodsPeriod prevalence was calculated using the number of people diagnosed with PD in the Shiprock Service Unit Indian Health Service database during 1995-1999, 2000-2004, and 2005-2009 as the numerator, and the number seen for any reason as the denominator. Age-standardized rates were calculated using the 2000 US population.ResultsDuring 2005-2009, 126 people were seen with PD (crude prevalence = 203.7/100,000 population). The age-adjusted rate was 335.9 (95% C. I. 277.8-394.0) overall, 438.5 (95% C.I. 336.5-540.5) in men and 259.7 (95% C.I. 192.8-326.7; p = 0.004) in women. The adjusted rate increased with age: 788.8 (95% C.I. 652.0-925.7) for age 40 and above to 1964.9 (95% C.I. 1613.7-2316.1) for age 60 and above. Adjusted rates were 246.6 (95% C.I. 187.2-306.0) in 1995-1999 and 284.7 (95% C.I. 227.0-342.4) in 2000-2004.ConclusionParkinson disease appears common among the Navajo. Estimates increased with age and time, and were higher in men. In-person interviews are needed to confirm these estimates, and to determine incidence, quality of care, and risk factors for PD among the Navajo.

Project description:West Nile virus (WNV) is a mosquito-borne virus of global importance. Over the last two decades, it has been responsible for significant numbers of cases of illness in humans and animals in many parts of the world. In Ukraine, WNV infections in humans and birds were first reported more than 25 years ago, yet the current epidemiological status is quite unclear. In this study, serum samples from over 300 equines were collected and screened in order to detect current WNV activity in Ukraine with the goal to estimate the risk of infection for humans and horses. Sera were tested by enzyme-linked immunosorbent assay (ELISA) and virus neutralization assay (NT) to detect WNV-specific antibodies. The results clearly revealed that WNV circulates in most of the regions from which samples were obtained, shown by a WNV seroprevalence rate of 13.5% of examined horses. This is the first topical report indicating the presence of WNV infections in horses in Ukraine, and the results of this study provide evidence of a widespread WNV circulation in this country.

Project description:ObjectiveTo estimate the point prevalence and cumulative incidence of caregiver-reported aggressive behaviors among people living with advanced Parkinson disease and related disorders (PDRDs) and secondarily examine variables associated with aggression.MethodsCaregivers from a clinical trial of outpatient palliative care for PDRD were surveyed about patient aggression at baseline and every 3 months over 12 months. Baseline responses were used for point prevalence. Cumulative incidence was calculated using responses from caregivers with no reported baseline aggression and available data at all other time points. Measures of disease severity, quality of life, mood, and caregiver burden were included in correlation and relative risk models, adjusting for age, sex, and diagnosis.ResultsOf 170 caregivers, 31 (18.2%) reported physical aggression, and 18 (10.6%) reported sexual aggression. Twelve-month cumulative incidence for physical and sexual aggression was 21.1% (23/109) and 16.0% (19/119), respectively. Physical aggression cumulative incidence was associated with patient depression (r = 0.37), patient-perceived quality of life (r = -0.26), caregiver burden (r = 0.26), caregiver-perceived patient quality of life (r = -0.26), and caregiver anxiety (r = 0.20). Age, sex, cognitive impairment, and dementia were not associated with aggression. No variables were associated with cumulative sexual aggression.ConclusionThere was a high prevalence and incidence of aggression in our PDRD cohort. This is an understudied issue in PDRD, and our findings highlight the need for increased awareness among neurologists. Providers should consider assessing for aggression when discussing neuropsychiatric symptoms or screening for caregiver burden. Future research should examine the relationship between aggression and patient and caregiver health outcomes.Trial registration informationClinical trial registration number: NCT02533921.

Project description:Background and purposeVariants in the glucocerebrosidase (GBA) gene are recognized as a common and important genetic risk factor for Parkinson disease (PD). However, the impact of variant severity on the clinical phenotype of PD in the Chinese population remains unclear. Thus, the present study aimed to determine the frequency of GBA-related PD (GBA-PD) and the relationship of GBA variant severity with clinical characteristics in a large Chinese cohort.MethodsLong-range polymerase chain reaction and next generation sequencing were performed for the entire GBA gene. GBA variant severity was classified into five classes: mild, severe, risk, complex, and unknown.ResultsAmong the total 737 PD patients, 47 GBA variants were detected in 79 (10.72%) patients, and the most common GBA variants were R163Q, L444P, and R120W. Complete demographic and clinical data were obtained for 673 patients, which revealed that 18.50% of early onset PD patients had GBA variants. Compared with patients without GBA variants, GBA-PD patients experienced PD onset an average of 4 years earlier and had more severe motor and nonmotor symptoms. Patients carrying severe and complex variants had a higher burden of nonmotor symptoms, especially depression, and more mood/cognitive and gastrointestinal symptoms than patients carrying mild variants.ConclusionsGBA-PD is highly prevalent in the Chinese population. The severity of GBA variants underlies distinct phenotypic spectrums, with PD patients carrying severe and complex variants seeming to have similar phenotypes. PD patient stratification by GBA variant severity should become a prerequisite for selecting specific treatments.

Project description:BackgroundGaucher disease (GD) is an inborn error of metabolism caused by mutations in the gene (GBA) coding for glucocerebrosidase (GCase), inherited in an autosomal recessive pattern. GD patients have up to 9% risk of developing PD.Case presentationWe report two patients with GD that developed PD at different disease stages.ConclusionWe reviewed the literature on the coexistence of PD and GD and speculate that the severity of symptoms may be related to the type of GBA mutation inherited.

Project description:Tobacco smoking is known to be a strong risk factor for developing many diseases. The development and severity of smoking dependence results from interaction of environmental and lifestyle factors, psycho-emotional predispositions, and also from genetic susceptibility. In present study, we investigated polymorphic variants in genes contributed to nicotine dependence, as well as to increased impulsivity, known to be an important risk factor for substance use disorders, in Ukraine population. The genotype frequencies at CYP2A6, DNMT3B, DRD2, HTR2A, COMT, BDNF, GABRA2, CHRNA5, and DAT1 polymorphisms were determined in 171 Ukraine residents, and these data were compared with data for several other European populations and main ethnic groups. It has been found that genotype frequencies for all studied loci are in Hardy-Weinberg equilibrium in the Ukrainian population and correspond to the respective frequencies in European populations. These findings suggest a similar impact of these loci on nicotine dependence in Ukraine. Further studies with larger sample sizes are, however, needed to draw firm conclusions about the effect size of these polymorphisms.

Project description:Olfactory dysfunction is one of the earliest features in Lewy-type alpha-synucleinopathies (LTS) such as Parkinson´s disease (PD). However, the underlying molecular mechanisms associated to smell impairment is poorly understood. To reveal the missing links in the biochemical understanding of olfactory dysfunction in PD, we have applied mass spectrometry-based proteomics in postmortem olfactory bulbs (OBs) dissected from parkinsonian subjects with different LTS staging respect to elderly controls (n= 24, mean age 79 years).

Project description:State-level variations in disease, healthcare utilization, and spending influence healthcare planning at federal and state levels and should be examined to understand national disparities in health outcomes. This descriptive study examined state-level variations in Parkinson disease (PD) prevalence, patient characteristics, Medicare spending, out-of-pocket costs, and health service utilization using data on 27.5 million Medicare beneficiaries in the US in 2014. We found that 45.8% (n = 179,496) of Medicare beneficiaries diagnosed with PD were women; 26.1% (n = 102,205) were aged 85+. The District of Columbia, New York, Illinois, Connecticut, and Florida had the highest age-, race-, and sex-adjusted prevalence of Parkinson disease among Medicare beneficiaries in the US. Women comprised over 48.5% of PD patient populations in West Virginia, Kentucky, Mississippi, Louisiana, and Arkansas. More than 31% of the PD populations in Connecticut, Pennsylvania, Hawaii, and Rhode Island were aged 85+. PD patients who were "dual-eligible"-receiving both Medicare and Medicaid benefits-also varied by state, from <10% to >25%. Hospitalizations varied from 304 to 653 stays per 1000 PD patients and accounted for 26.5% of the 7.9 billion United States Dollars (USD) paid by the Medicare program for healthcare services delivered to our sample. A diagnosis of PD was associated with greater healthcare use and spending. This study provides initial evidence of substantial geographic variation in PD patient characteristics, health service use, and spending. Further study is necessary to inform the development of state- and federal-level health policies that are cost-efficient and support desired outcomes for PD patients.
