We performed genome-wide tests for association between haplotype clusters and each of 9 metabolic traits in a cohort of 5402 Northern Finnish individuals genotyped for 330 000 single-nucleotide polymorphisms. The metabolic traits were body mass index, C-reactive protein, diastolic blood pressure, glucose, high-density lipoprotein (HDL), insulin, low-density lipoprotein (LDL), systolic blood pressure, and triglycerides. Haplotype clusters were determined using Beagle. There were LDL-associated clusters in the chromosome 4q13.3-q21.1 region containing the albumin (ALB) and platelet factor 4 (PF4) genes. This region has not been associated with LDL in previous genome-wide association studies. The most significant haplotype cluster in this region was associated with 0.488 mmol/l higher LDL (95% CI: 0.361–0.615 mmol/l, P-value: 6.4 × 10−14). We also observed three previously reported associations: Chromosome 16q13 with HDL, chromosome 1p32.3-p32.2 with LDL and chromosome 19q13.31-q13.32 with LDL. The chromosome 1 and chromosome 4 LDL associations do not reach genome-wide significance in single-marker analyses of these data, illustrating the power of haplotypic association testing. 相似文献
During the ongoing public health crisis, many agencies are reporting COVID-19 health outcome information based on the overall population. This practice can lead to misleading results and underestimation of high risk areas. To gain a better understanding of spatial and temporal distribution of COVID-19 deaths; the long term care facility (LTCF) and household population (HP) deaths must be used. This approach allows us to better discern high risk areas and provides policy makers with reliable information for community engagement and mitigation strategies. By focusing on high-risk LTCFs and residential areas, protective measures can be implemented to minimize COVID-19 spread and subsequent mortality. These areas should be a high priority target when COVID-19 vaccines become availableDuring the current public health crisis, many agencies and media outlets are reporting COVID-19 health outcome information based on the overall population of Cook County. As we have demonstrated, overall COVID-19 case counts and mortality can be misleading (details in >Story Map 1). Moreover, they offer little guidance for delivering public health interventions to high risk populations, a critical need during this second and potentially more devastating wave of the pandemic. The University of Illinois Chicago School of Public Health’s Public Health Geographic Information System Program (UIC-SPH-PHGIS) and Purdue research team has been examining spatial and temporal patterns of COVID-19 mortality with a focus on the significant loss of life from COVID-19 among Long-Term Care Facility (LTCF) residents in contrast to mortality in the community among residents of private households (non-LTCF; referred to as household population, HP). The goals of the study are:
Improve the accuracy of commonly quoted COVID-19 mortality indicators;
Gain a better understanding of spatial and temporal distribution of COVID-19 deaths;
Examine the role of race, ethnicity, and socioeconomic status in COVID-19 mortality;
Identify population and organizational parameters that can inform strategies for public health interventions.
Prioritizing the allocation of resources based on reliable information is a prerequisite of a successful mitigation strategy and immunization plan. Findings from our research have significant practical implications. The state and federal government face a series of policy decisions both due to the recent surge in positive cases and, when the time comes, the need to rationalize distribution of vaccines to high priority groups beyond healthcare workers and nursing home residents in critical areas. The research team seeks to modify prevailing practices in order to derive reliable information that guides policy decisions. At this stage of the study, we identified high-risk LTCFs and residential areas (HP) of Cook County from readily available, real-time mortality data. 相似文献
ObjectivesTo determine the positive predictive value (PPV) of disc haemorrhages (DHs) for the diagnosis of open angle glaucoma (OAG).MethodsA retrospective review of 618 consecutive new referrals by community optometrists to a hospital glaucoma service, including 54 patients with DHs. All patients had a comprehensive eye examination. The primary outcome was whether the patient was diagnosed with OAG in either eye, with a secondary outcome of whether they were discharged at the first visit (first visit discharge rate, FVDR).Results54 of 618 patients (8.7%) had a DH noted at the time of referral, including 21 referred with DH alone. 29 patients with DHs were diagnosed with OAG for a PPV of 54% (95% CI 40–67%), falling to 24% (95% CI 8–47%) in those with DH alone. The overall FVDR was 35%, increasing to 57% in those referred due to DH alone. The FVDR for those referred with DH alone was significantly higher than the FDVR of 25% among the 564 patients referred with suspected glaucoma without a DH (P = 0.001). The FVDR decreased to 35% for patients with a DH plus one other feature of glaucoma and to 0% for patients with a DH and at least two other features suggestive of glaucoma.ConclusionsAlmost 60% of patients referred due to isolated DHs were discharged at the first visit to the glaucoma clinic, however almost one in four was diagnosed with OAG. Patients with DH and other features suggestive of glaucoma had a higher probability of glaucoma diagnosis.Subject terms: Physical examination, Health care, Optic nerve diseases相似文献
Personality traits such as Neuroticism and Conscientiousness are associated with Alzheimer disease (AD) pathophysiology in cognitively normal (CN) and impaired individuals, and may represent potential risk or resilience factors, respectively. This study examined the cross-sectional relationship between personality traits and regional tau deposition using positron emission tomography (PET) in cognitively normal older adults. A cohort of CN (Clinical Dementia Rating (CDR) 0, n =?128) older adults completed the NEO Five-Factor Inventory to assess traits of Neuroticism, Extroversion, Openness, Agreeableness, and Conscientiousness and underwent tau-PET and β-amyloid (Aβ)-PET imaging. We utilized linear regression models, adjusting for age, sex, geriatric depression score, and Aβ to evaluate the association between each of the personality traits and regional tau-PET accumulation. Elevated Neuroticism scores were associated with higher tau-PET accumulation in the amygdala (p =?.002), entorhinal cortex (p =?.012), and inferior temporal cortex (p =?.016), as well as with a composite tau-PET measure (p =?.002). In contrast, Extroversion, Openness, Agreeableness, and Conscientiousness were not associated with tau deposition in any of these regions (p’s?>?0.160). Our results indicate that increased Neuroticism is associated with higher tau pathophysiology in regions known to be vulnerable to AD pathophysiology in CN participants. High Neuroticism scores may therefore serve as a potential risk factor for tau accumulation. Alternatively, personality can change with the onset of AD, thus increased tau levels may affect Neuroticism scores. While future longitudinal studies are needed to determine directionality, our findings suggest early associations between Neuroticism and tau accumulation in CN adults.
