<h4>Importance</h4>As many as 60% of patients with Parkinson disease (PD) experience psychosis, 80% develop dementia, and the use of antipsychotics (APs) in the population with PD is common. The use of APs by patients with dementia in the general population is associated with increased mortality, but whether this risk extends to patients with PD remains unknown.<h4>Objective</h4>To determine whether AP use in patients with PD is associated with increased mortality.<h4>Design, setting, and partic ...[more]

Project description:BackgroundNeuroinflammation may contribute to the pathogenesis of Parkinson disease (PD). Use of nonsteroidal anti-inflammatory drugs (NSAID) in general, and possibly ibuprofen in particular, has been shown to be related to lower PD risk in previous epidemiologic studies.MethodsWe prospectively examined whether use of ibuprofen or other NSAIDs is associated with lower PD risk among 136,197 participants in the Nurses' Health Study (NHS) and the Health Professionals Follow-up Study (HPFS) free of PD at baseline (1998 for NHS and 2000 for HPFS). NSAIDs use was assessed via questionnaire. Results were combined in a meta-analysis with those of published prospective investigations.ResultsWe identified 291 incident PD cases during 6 years of follow-up. Users of ibuprofen had a significantly lower PD risk than nonusers (relative risk [RR], adjusted for age, smoking, caffeine, and other covariates = 0.62; 95% confidence interval [CI] 0.42-0.93; p = 0.02). There was a dose-response relationship between tablets of ibuprofen taken per week and PD risk (p trend = 0.01). In contrast, PD risk was not significantly related to use of aspirin (RR = 0.99; 95% CI 0.78-1.26), other NSAIDs (RR = 1.26; 95% CI 0.86-1.84), or acetaminophen (RR = 0.86; 95% CI 0.62-1.18). Similar results were obtained in the meta-analyses: the pooled RR was 0.73 (95% CI 0.63-0.85; p < 0.0001) for ibuprofen use, whereas use of other types of analgesics was not associated with lower PD risk.ConclusionsThe association between use of ibuprofen and lower PD risks, not shared by other NSAIDs or acetaminophen, suggests ibuprofen should be further investigated as a potential neuroprotective agent against PD.

Project description:ImportanceParkinson disease (PD) is an increasingly common neurodegenerative disorder in many aging societies. Although comorbidities with mental disorders are common in PD, whether PD is associated with an increased risk of suicide is unclear.ObjectiveTo use a large national representative PD cohort to compare the risk of suicide in patients with PD and control participants and identify potential risk factors.Design, setting, and participantsThis nationwide population-based cohort study used linked data from Taiwan's National Health Insurance data set and Taiwan Death Registry between January 2002 and December 2016. Patients with incident PD diagnosed between January 2005 and December 2014 were followed up until December 2016. Four control participants from the general population were randomly selected by risk set sampling and were matched on age, sex, and residence to each affected individual. Data analysis occurred from June 2019 to October 2020.ExposuresDiagnosis of PD retrieved from the National Health Insurance data set.Main outcomes and measuresSuicide was recorded in the Taiwan Death Registry. Cox proportional models and hazard ratios (HRs) were used to estimate the association between PD and the risk of suicide over the follow-up period.ResultsOver 11 years, 35 891 patients with PD were followed up (17 482 women [48.7%]; mean [SD] age, 72.5 [10.1] years) and matched to 143 557 control participants (69 928 women [48.7%]; mean [SD] age, 72.5 [10.1] years). A total of 151 patients with PD (cumulative incidence, 66.6 per 100 000 [95% confidence limits [CL], 78.1-91.7]) and 300 control participants (cumulative incidence, 32.3 per 100 000 [95% CL, 36.2-40.5]) died by suicide. The risk of suicide was higher (HR, 2.1 [95% CL, 1.7-2.5]) in patients with PD than control participants, after adjustment for markers of socioeconomic position, medical comorbidities, and dementia. After controlling for mental disorders, the association between PD and suicide risk remained (HR, 1.9 [95% CL, 1.6-2.3]). Compared with control participants who died by suicide, those who died by suicide in the PD group were slightly younger (mean [SD] age: patients with PD, 74.0 [10.4] years vs control participants, 76.0 [10.2] years; P = .05) and more likely to be urban dwelling (medium urbanization, 39 patients with PD [25.8%] vs 115 control participants [38.3%]; high urbanization, 84 patients with PD [55.6%] vs 136 control participants [45.3%]; P = .03), have mental disorders (depression, 15 of 151 patients with PD [9.9%] vs 15 of 300 control participants [5.0%]; other mental disorders, 12 patients with PD [8.0%] vs 11 control participants [3.7%]; P = .02), and adopt jumping as a method of suicide (21 patients with PD [13.9%] vs 16 control participants [5.3%]; P < .01).Conclusions and relevanceIn this population-based cohort study, Parkinson disease, a common neurodegenerative disorder common in elderly persons, was independently associated with an increased risk of suicide. Integrating mental health care into primary care and PD specialty care, along with socioenvironmental interventions, may help decrease the risk of suicide in patients with PD.

Project description:BACKGROUND:Recent data showed that melanoma was more common among patients with Parkinson disease than individuals without Parkinson disease and vice versa. It has been hypothesized that these two diseases may share common genetic and environmental risk factors. METHODS:We evaluated the association between single-nucleotide polymorphisms (SNP) selected on the basis of recent genome-wide association studies (GWAS) on Parkinson disease risk and the risk of melanoma using 2,297 melanoma cases and 6,651 controls. RESULTS:The Parkinson disease SNP rs156429 in the chromosome 7p15 region was nominally associated with melanoma risk with P value of 0.04, which was not significant after the Bonferroni correction for multiple comparisons. No association was observed between the remaining 31 Parkinson disease SNPs and the risk of melanoma. The genetic score based on the number of Parkinson disease risk allele was not associated with melanoma risk [OR for the highest genetic score quartile (30-35) vs. the lowest (15-20), 1.13, 95% confidence interval (CI), 0.47-2.70]. CONCLUSION:The Parkinson disease SNPs identified in published GWAS do not seem to play an important role in melanoma development. IMPACT:The Parkinson disease susceptibility loci discovered by GWAS contribute little to the observed epidemiologic association between the Parkinson disease and melanoma.

Project description:BackgroundAntipsychotics are used in Parkinson disease (PD) to treat psychosis, mood, and behavioral disturbances. Commonly used antipsychotics differ substantially in their potential to worsen motor symptoms through dopaminergic receptor blockade. Recent real-world data on the use and continuation of antipsychotic therapy in PD are lacking. The objectives of this study are to (1) examine the continuation of overall and initial antipsychotic therapy in individuals with PD and (2) determine whether continuation varies by drug dopamine receptor blocking activity.MethodsWe conducted a retrospective cohort study using U.S. commercially insured individuals in Optum 2001-2019. Adults aged 40 years or older with PD initiating antipsychotic therapy, with continuous insurance coverage for at least 6 months following drug initiation, were included. Exposure to pimavanserin, quetiapine, clozapine, aripiprazole, risperidone, or olanzapine was identified based on pharmacy claims. Six-month continuation of overall and initial antipsychotic therapy was estimated by time to complete discontinuation or switching to a different antipsychotic. Cox proportional hazards models evaluated factors associated with discontinuation.ResultsOverall, 38.6% of 3566 PD patients in our sample discontinued antipsychotic therapy after the first prescription, 61.4% continued with overall treatment within 6 months of initiation. Clozapine use was too rare to include in statistical analyses. Overall therapy discontinuation was more likely for those who initiated medications with known dopamine-receptor blocking activity (adjusted hazard ratios 1.76 [95% confidence interval 1.40-2.20] for quetiapine, 2.15 [1.61-2.86] for aripiprazole, 2.12 [1.66-2.72] for risperidone, and 2.07 [1.60-2.67] for olanzapine), compared with serotonin receptor-specific pimavanserin. Initial antipsychotic therapy discontinuation also associated with greater dopamine-receptor blocking activity medication use - adjusted hazard ratios 1.57 (1.28-1.94), 1.88 (1.43-2.46), 2.00 (1.59-2.52) and 2.03 (1.60-2.58) for quetiapine, aripiprazole, risperidone, and olanzapine, respectively, compared with pimavanserin. Similar results were observed in sensitivity analyses.ConclusionsOver one-third of individuals with PD discontinued antipsychotic therapy, especially if the initial drug has greater dopamine-receptor blocking activity. Understanding the drivers of antipsychotic discontinuation, including ineffectiveness, potentially inappropriate use, clinician inertia, patient adherence and adverse effects, is needed to inform clinical management of psychosis in PD and appropriate antipsychotic use in this population.

Project description:Purpose of reviewThe prevalence of diabetes is 2-3-fold higher in people with severe mental illness than the general population. There are concerns that antipsychotics increase the risk of diabetes. This review will examine the latest epidemiological studies linking antipsychotics and diabetes, as well as the mechanisms underlying the association and the clinical implications to minimise the impact of antipsychotics on metabolic health.Recent findingsAlthough there is an increased risk of diabetes in people with first-episode psychosis, the prevalence increases rapidly after antipsychotics are started. Antipsychotics likely increase the risk of diabetes through weight gain and directly by adversely affecting insulin sensitivity and secretion. It is important to implement measures to prevent diabetes, to screen for diabetes to ensure prompt diagnosis and to provide effective diabetes care. Further research is needed to understand how antipsychotics cause diabetes and to improve the clinical management of diabetes in people with severe mental illness.

Project description:ObjectiveTo identify biotypes in patients with newly diagnosed Parkinson disease (PD) and to test whether these biotypes could explain interindividual differences in longitudinal progression.MethodsIn this longitudinal analysis, we use a data-driven approach clustering PD patients from the Parkinson's Progression Markers Initiative (n = 314, age 61.0 ± 9.5, years 34.1% female, 5 years of follow-up). Voxel-level neuroanatomic features were estimated with deformation-based morphometry (DBM) of T1-weighted MRI. Voxels with deformation values that were significantly correlated (p < 0.01) with clinical scores (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale Parts I-III and total score, tremor score, and postural instability and gait difficulty score) at baseline were selected. Then, these neuroanatomic features were subjected to hierarchical cluster analysis. Changes in the longitudinal progression and neuroanatomic pattern were compared between different biotypes.ResultsTwo neuroanatomic biotypes were identified: biotype 1 (n = 114) with subcortical brain volumes smaller than heathy controls and biotype 2 (n = 200) with subcortical brain volumes larger than heathy controls. Biotype 1 had more severe motor impairment, autonomic dysfunction, and much worse REM sleep behavior disorder than biotype 2 at baseline. Although disease durations at the initial visit and follow-up were similar between biotypes, patients with PD with smaller subcortical brain volume had poorer prognosis, with more rapid decline in several clinical domains and in dopamine functional neuroimaging over an average of 5 years.ConclusionRobust neuroanatomic biotypes exist in PD with distinct clinical and neuroanatomic patterns. These biotypes can be detected at diagnosis and predict the course of longitudinal progression, which should benefit trial design and evaluation.

Project description:ObjectiveTo characterize how disease progression is associated with mortality in a large cohort of patients with Parkinson disease (PD) with long-term follow-up after subthalamic nucleus deep brain stimulation (STN-DBS).MethodsMotor and cognitive disabilities were assessed before and 1, 2, 5, and 10 years after STN-DBS in 143 consecutive patients with PD. We measured motor symptoms "off" and "on" levodopa and STN-DBS and recorded causes of death. We used linear mixed models to characterize symptom progression, including interactions between treatment conditions and time to determine how treatments changed efficacy. We used joint models to link symptom progression to mortality.ResultsMedian observation time was 12 years after surgery, during which akinesia, rigidity, and axial symptoms worsened, with mean increases of 8.8 (SD 6.5), 1.8 (3.1), and 5.4 (4.1) points from year 1-10 after surgery ("on" dopamine/"on" STN-DBS), respectively. Responses to dopaminergic medication and STN-DBS were attenuated with time, but remained effective for all except axial symptoms, for which both treatments and their combination were predicted to be ineffective 20 years after surgery. Cognitive status significantly declined. Forty-one patients died, with a median time to death of 9 years after surgery. The current level of axial disability was the only symptom that significantly predicted death (hazard ratio 4.30 [SE 1.50] per unit of square-root transformed axial score).ConclusionsWe quantified long-term symptom progression and attenuation of dopaminergic medication and STN-DBS treatment efficacy in patients with PD and linked symptom progression to mortality. Axial disability significantly predicts individual risk of death after surgery, which may be useful for planning therapeutic strategies in PD.

Project description:ImportanceRandomized controlled trials have demonstrated increased all-cause mortality in elderly patients with dementia treated with newer antipsychotics. It is unknown whether this risk generalizes to non-elderly adults using newer antipsychotics as augmentation treatment for depression.ObjectiveThis study examined all-cause mortality risk of newer antipsychotic augmentation for adult depression.DesignPopulation-based new-user/active comparator cohort study.SettingNational healthcare claims data from the US Medicaid program from 2001-2010 linked to the National Death Index.ParticipantsNon-elderly adults (25-64 years) diagnosed with depression who after ≥3 months of antidepressant monotherapy initiated either augmentation with a newer antipsychotic or with a second antidepressant. Patients with alternative indications for antipsychotic medications, such as schizophrenia, psychotic depression, or bipolar disorder, were excluded.ExposureAugmentation treatment for depression with a newer antipsychotic or with a second antidepressant.Main outcomeAll-cause mortality during study follow-up ascertained from the National Death Index.ResultsThe analytic cohort included 39,582 patients (female = 78.5%, mean age = 44.5 years) who initiated augmentation with a newer antipsychotic (n = 22,410; 40% = quetiapine, 21% = risperidone, 17% = aripiprazole, 16% = olanzapine) or with a second antidepressant (n = 17,172). The median chlorpromazine equivalent starting dose for all newer antipsychotics was 68mg/d, increasing to 100 mg/d during follow-up. Altogether, 153 patients died during 13,328 person-years of follow-up (newer antipsychotic augmentation: n = 105, follow-up = 7,601 person-years, mortality rate = 138.1/10,000 person-years; antidepressant augmentation: n = 48, follow-up = 5,727 person-years, mortality rate = 83.8/10,000 person-years). An adjusted hazard ratio of 1.45 (95% confidence interval, 1.02 to 2.06) indicated increased all-cause mortality risk for newer antipsychotic augmentation compared to antidepressant augmentation (risk difference = 37.7 (95%CI, 1.7 to 88.8) per 10,000 person-years). Results were robust across several sensitivity analyses.ConclusionAugmentation with newer antipsychotics in non-elderly patients with depression was associated with increased mortality risk compared with adding a second antidepressant. Though these findings require replication and cannot prove causality, physicians managing adults with depression should be aware of this potential for increased mortality associated with newer antipsychotic augmentation.

Project description:ImportanceGiven the burden of chronic liver disease on the health care system, more information on the hepatoprotective association of statins in the general population is needed.ObjectiveTo examine whether regular statin use is associated with a reduction in liver disease, particularly hepatocellular carcinoma (HCC) and liver-related deaths, in the general population.Design, setting, and participantsThis cohort study used data from the UK Biobank (UKB) (individuals aged 37-73 years) collected from baseline (2006-2010) to the end of follow-up in May 2021, from the TriNetX cohort (individuals aged 18-90 years) enrolled from baseline (2011-2020) until end of follow-up in September 2022, and from the Penn Medicine Biobank (PMBB) (individuals aged 18-102 years) with ongoing enrollment starting in 2013 to the end of follow-up in December 2020. Individuals were matched using propensity score matching according to the following criteria: age, sex, body mass index, ethnicity, diabetes with or without insulin or biguanide use, hypertension, ischemic heart disease, dyslipidemia, aspirin use, and number of medications taken (UKB only). Data analysis was performed from April 2021 to April 2023.ExposureRegular statin use.Main outcomes and measuresPrimary outcomes were liver disease and HCC development as well as liver-associated death.ResultsA total of 1 785 491 individuals were evaluated after matching (aged 55 to 61 years on average, up to 56% men, and up to 49% women). A total of 581 cases of liver-associated death, 472 cases of incident HCC, and 98 497 new liver diseases were registered during the follow-up period. Individuals were aged 55-61 years on average, with a slightly higher proportion of men (up to 56%). In UKB individuals (n = 205 057) without previously diagnosed liver disease, statin users (n = 56 109) had a 15% lower hazard ratio (HR) for the association of developing a new liver disease (HR, 0.85; 95% CI, 0.78-0.92; P < .001). In addition, statin users demonstrated a 28% lower HR for the association with liver-related death (HR, 0.72; 95% CI, 0.59-0.88; P = .001) and a 42% lower HR for the development of HCC (HR, 0.58; 95% CI, 0.35-0.96; P = .04). In TriNetX individuals (n = 1 568 794), the HR for the association of HCC was reduced even further for statin users (HR, 0.26; 95% CI, 0.22-0.31; P = .003). The hepatoprotective association of statins was time and dose dependent, with a significant association in PMBB individuals (n = 11 640) for incident liver diseases after 1 year of statin use (HR, 0.76; 95% CI, 0.59-0.98; P = .03). Taking statins was particularly beneficial in men, individuals with diabetes, and individuals with a high Fibrosis-4 index at baseline. Carriers of the heterozygous minor allele of PNPLA3 rs738409 benefited from statin use and had a 69% lower HR for the association with HCC (UKB HR, 0.31; 95% CI, 0.11-0.85; P = .02).Conclusions and relevanceThis cohort study indicates substantial preventive associations of statins against liver disease, with an association with duration and dose of intake.

Project description:ImportanceGreater diet quality and physical activity level are associated with a lower risk of developing Parkinson disease (PD). However, information regarding the association between lifestyle behaviors and survival after PD diagnosis remains limited.ObjectiveTo examine the association of prediagnosis and postdiagnosis overall diet quality and physical activity with all-cause mortality among individuals with PD.Design, setting, and participantsThis population-based cohort study analyzed male participants in the Health Professionals Follow-up Study from 1986 to 2012 and female participants in the Nurses' Health Study from 1984 to 2012. Participants who were diagnosed with PD and had complete baseline dietary assessment data were included. Data were analyzed from January 2021 to February 2022.ExposuresPrediagnosis diet quality, assessed by the Alternative Healthy Eating Index (AHEI), and physical activity, assessed by metabolic equivalent task (MET) hours per week reported on questionnaires, were the primary exposures of interest to minimize reverse causation.Main outcomes and measuresMortality, which was followed up until 2018, was the primary outcome. Cox proportional hazards regression models were used to estimate the association of diet and physical activity with mortality individually and jointly, and the models were adjusted for age, total energy intake, caffeine intake, and other lifestyle risk factors.ResultsThe sample comprised 1251 individuals with PD, which included 652 men (52.1%) with a median (IQR) age at diagnosis of 73.4 (67.5-78.7) years. During the 32 to 34 years of follow-up, 942 participants died. The adjusted hazard ratio (HR) comparing the highest vs the lowest AHEI quartile was 0.69 (95% CI, 0.56- 0.85) for prediagnosis analyses and 0.57 (95% CI, 0.42-0.78) for postdiagnosis analyses. Similar results were obtained for cumulative mean MET hours per week in the prediagnosis analyses (HR, 0.71; 95% CI, 0.57-0.87) and postdiagnosis analyses (HR, 0.47; 95% CI, 0.35-0.63). The inverse association persisted for PD-specific mortality (postdiagnosis AHEI: HR, 0.52 [95% CI, 0.33-0.80]; postdiagnosis physical activity: HR, 0.37 [95% CI, 0.25-0.55]). In the joint analyses of diet quality and physical activity before the PD diagnosis, the adjusted HR was 0.51 (95% CI, 0.36-0.73) for individuals in the highest vs lowest tertiles for both variables. The HR for diet quality and physical activity after the diagnosis was 0.35 (95% CI, 0.23-0.52).Conclusions and relevanceResults of this study showed that a healthy dietary pattern and an active lifestyle were associated with a lower rate of all-cause mortality among individuals with PD. Consuming a healthy diet and engaging in physical activity or exercise could be targeted to improve PD outcomes.
