racial differences in the diagnosis of parkinson's disease

A community-based survey. Lifetime risk estimates are useful in clinical practice, epidemiologic research, and public health. While instruments exist to measure patients' beliefs about medications in general, no such tool exists for PD. We used all Medicare fee-for-service claims data for 1998 through 2000 to determine the incidence of knee arthroplasty according to Hospital Referral Region, sex, and race or ethnic group. Hazard ratios (HRs) and the incidence rate of subsequent PD were calculated for both cohorts and separately for male and female groups. Imran S, Patel RS, Onyeaka HK, Tahir M, Madireddy S, Mainali P, Hossain S, Rashid W, Queeneth U, Ahmad N. Cureus. In addition, we investigated their potential interactions with environmental factors and specific clinical outcomes (motor and cognitive impairments, depression, and anxiety). Conclusions Our study identified no association between gout and PD in Taiwan. Administrative claims can provide fairly accurate and practical approach to “rule in” patients with PD. Internal consistency was acceptable (Cronbach's alpha = 0.67). 2020 Mar 10;12:60. doi: 10.3389/fnagi.2020.00060. ... Parkinson's disease displays racial differences as can be seen from recent studies which have shown that incidence of PD in African-Americans is lower than in Caucasian whites and Asians [2, ... [63][64][65] The findings that PD risk increases with decreasing darkness of hair color suggest a potential role of pigmentation in PD. Methods Before surgery, men and women patient groups were comparable in clinical severity, except the women were associated with slightly inferior cognition (P<0.05) and relatively better levodopa (LD) response (P<0.05) than the men. Front Aging Neurosci. Although there is convincing epidemiologic evidence of a negative association between PD and most cancers, a notable exception to this is that melanoma, a malignant tumor of melanin-producing cells in skin, occurs with higher-than-expected frequency among subjects with PD and that melanoma patients are more likely to have PD.

Further, the G-rs356219 and C-rs2736990 alleles were associated with early onset PD. Tolterodine and tamsulosin were the most common therapeutic agents, respectively prescribed to 38.5% and 27.3% of the patients. Neurology 1985;35(6):841–845. To measure receipt of necessary coronary artery bypass graft (CABG) surgery and percutaneous transluminal coronary angioplasty (PTCA) overall; by patient sex, ethnicity, and payer status; and by availability of on-site revascularization. National Center for Health Statistics: urban–rural classifi-cation scheme for counties; 2006. In many cases, parkinsonism develops gradually. The mean length of stay (LOS) was higher in PD patients with psychosis compared to PD with depression (7.32 days vs. 4.23 days; P < 0.001), though the mean total charges of hospitalization were lower in psychosis ($31,240 vs. $38,581; P < 0.001). Single locus analysis showed that the risk allele of all SNPs were more frequent in PD patients (p < 0.05), and the associations of SNPs rs2583988, rs356219, and rs2736990 with increased PD risk were confirmed. Latinos were the next most prone with an incidence of 40 per 100,000. Val66Met is a common polymorphism of the BDNF gene that affects cognitive and motor processes. We analyzed 2001-2011 inpatient and outpatient visit data for Navajo people obtained from the Indian Health Service, which provides health care to American Indian people living on the Navajo Reservation. This association between PD and melanoma offers a unique opportunity to understand PD. Other treatments included catheterization, botulinum toxin A bladder wall injection, transurethral resection of the prostate and urethral dilatation. The rate for men (19.0 per 100,000, 95% CI: 16.1, 21.8) was 91% higher than that for women (9.9 per 100,000, 95% CI: 7.6, 12.2). The National Academies Press; Washington DC: 2003. The panel was composed of two subpanels: one consisting of all but two neurologists and neurosurgeons in greater Baltimore ("neurological panel") and the other comprising a stratified sample of other practicing physicians in the area ("nonneurological panel"). Dahodwala and colleagues analyzed Medicaid data from Pennsylvania and found that African Americans were half as likely to be diagnosed with PD as compared to whites, ... Dahodwala and colleagues analyzed Medicaid data from Pennsylvania and found that African Americans were half as likely to be diagnosed with PD as compared to whites [15]. Both Parkinson’s Disease (PD) and Essential tremor (ET), are nervous system disorders. Brain MRI revealed a greater severity of white matter changes in Black compared to the White and Asian cohorts. PD is more common in the white population than in black or Asian population (Van Den Eeden et al., 2003; ... For example, MS occurs 3 times as often in women as in men 66 , and although MS has long been considered as affecting people of predominantly northern European ancestry, African Americans have a higher incidence of MS and exhibit different disease phenotypes compared to Caucasians 67-69 ; non-white Hispanics may have a lower incidence of MS 68 . Conclusion: A second 3′UTR SNP (rs356165) associates with moderate AEI and enhances SNCA mRNA expression. Accordingly, we executed the present study with the purpose of assessing PD risk in patients with gout. 192 (91%) of the older adults completed more than 90% of the survey. No specific test exists to diagnose Parkinson's disease. The concept that the skin is a mirror of Parkinson's disease dates to the start of the last century. Our literature review focused on prevalence, treatment and diagnosis discrepancies, and racial variations in the perceptions of aging. Crude and age-adjusted incidence and prevalence rates were calculated overall as well as by age, sex, region of residence, and time period. 2011;36(3):150-4. doi: 10.1159/000324935. The difference in incidence of PD among different racial groups may provide additional insight into the etiology. Also genetic testing and various other ancillary tests, such as olfactory testing, MRI, and dopamine-transporter single-photon-emission computed-tomography imaging, help with clinical diagnostic decisions. Brandon Mahal, MD, joins Charles Ryan, MD, to discuss what he reported in this New England Journal of Medicine paper titled "Racial Differences in Genomic Profiling of Prostate Cancer. The important question is, Do women, minorities, and the uninsured fail to receive cardiac procedures when they need them? Background: This work provides original and reliable data to improve our knowledge of ALS in Africa and Latin America. This may be due to true biological differences in the risk of Parkinson's disease or to underdiagnosis because of barriers to health care, such as education or cultural beliefs about health and aging. This is a multicentre (four sites, London), real-life, cross-sectional study including PD patients of BAME or White ethnicity. We found that mice of the same strain had more similar profiles compared to those of different strains, and also identified strains and phenotypic parameters in which sex played a significant role in profile differences. Different study designs may partially account for the conflicting results. There is wide variation in racial disparities across geographic lines: some areas have substantial disparities, while others have equal treatment. Every year, about 60,000 Americans are newly diagnosed with the disease, though likely many more go undiagnosed (1). Because of the opposite effect of higher incidence and higher mortality rates in men, the lifetime risks were only slightly higher in men than in women. Dahodwala N, Xie M, Noll E, Siderowf A, Mandell DS. Conclusions: Parkinson's disease (PD) is the second most common neurodegenerative disease, though evidence suggests that this disorder does not affect all racial groups similarly. Negative beliefs about PD treatments are associated with lower quality of life and may be related to medication non-adherence. Eldridge R, Osorio D, Amstalden K, Edwards C, Young CR, Cai JJ, Konganti K, Hillhouse A, Threadgill DW, Welsh CJ, Brinkmeyer-Langford C. Sci Rep. 2020 May 13;10(1):7918. doi: 10.1038/s41598-020-64862-z. These reflections assume even greater importance considering that, although most of migratory movements take place between European countries, a sizeable proportion of PD cases will affect subjects coming from developing countries and reasonably composing minority groups once they moved to Europe (thus probably with lower socioeconomic status and reduced access to care [1]). Little research investigates the role of patient-physician communication in understanding racial disparities in depression treatment. Conditions other than PD may have one or more of these symptoms, mimicking Parkinson’s. The National Academies Press. (Johns Hopkins Univ. Countywide density of neurological surgeons and Hispanic ethnicity were not significant predictors. Clipboard, Search History, and several other advanced features are temporarily unavailable. African-American patients had fewer years of education and reported poorer physical health than whites. For diagnosis, doctors take a thorough medical history and may request a number of movement tests. Gender may also prove to be a relevant factor when choosing appropriate treatment”, Dr Kojovic commented. © 2015 International Parkinson and Movement Disorder Society. In this case, after discarding the iatrogenic etiology, it was considered an association of paranoid schizophrenia with symptoms and signs of Parkinsonism, identiiied as Parkinson plus or atypical Parkinson syndrome, being impossible to differentiate between a MSA or PSP, based on scintigraphy with IBZM. Although the exact cause of the dopaminergic neurodegeneration remains elusive, recent postmortem and experimental studies have revealed an essential role for neuroinflammation that is initiated and driven by activated microglial and infiltrated peripheral immune cells and their neurotoxic products (such as proinflammatory cytokines, reactive oxygen species, and nitric oxide) in the pathogenesis of PD. When compared with their FFS counterparts, African-American MC enrollees are twice as likely to report problems in obtaining needed care, and Hispanic MC enrollees are nearly twice as likely to rate the extent to which their providers care about them as "fair" or "poor."
