Abstract
INTRODUCTION Research efforts to characterize and evaluate care delivery and outcomes for older adults with cancer and comorbid dementia are limited by varied methods used to classify Alzheimer's disease and related dementias (ADRD). The purpose of this study is to evaluate differences in demographic, clinical, and cancer characteristics of people newly diagnosed with cancer and concomitant dementia comparing two common methods to identify ADRD using administrative claims data. MATERIALS AND METHODS We conducted a retrospective cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Our sample included adults aged 66 years and older with a first primary diagnosis of lung or colorectal cancer between 2011 and 2017. For each cancer diagnosis, we constructed analytical cohorts using the Center for Medicare and Medicaid Services' Chronic Condition Warehouse (CCW) flag and the Bynum-Standard one- and three-year algorithms to capture diagnosed ADRD. We estimated ADRD prevalence using the algorithms and compared Bynum and CCW cohorts on demographic, clinical, and cancer characteristics at cancer diagnosis and survival for lung and colorectal cancer separately. RESULTS Among older adults with lung cancer, ADRD prevalence was 4.7% with the one-year Bynum, 6.5% with the three-year Bynum, and 12.5% using the CCW flag. In the colorectal cohort, ADRD prevalence was 5.6% with the one-year Bynum, 7.6% with the three-year Bynum, and 14.1% with the CCW flag. Demographic characteristics were similar across ADRD cohorts. The Bynum cohorts identified higher proportions of individuals with moderate to severe dementia (13.8% and 11.2% versus 7.1% CCW in lung cancer; 13.1% and 10.6% versus 6.8% CCW in colorectal cancer), higher frailty rates (27.4% and 22.7% versus 15.0% CCW in lung cancer; 26.4% and 22.3% versus 14.8% CCW in colorectal cancer). Median survival was lower for the Bynum cohorts compared to the CCW, regardless of cancer type. DISCUSSION Findings demonstrate that ADRD prevalence and certain clinical characteristics vary based on dementia ascertainment method and observation period used to classify individuals with ADRD. Considering differences in the cohorts of registry cases generated by the identification method used is essential when interpreting findings related to treatment, utilization, and outcomes within and across cancer cohorts.

Optimizing environmental enrichment for Sprague Dawley rats: Exemplary insights into the liver proteome. PLoS One 2024; 19:e0297497. [PMID: 38635534 PMCID: PMC11025844 DOI: 10.1371/journal.pone.0297497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 01/07/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Considering the expected increase in the elderly population and the growing emphasis on aging-related biomedical research, the demand for aged laboratory animals has surged, challenging established husbandry practices. Our objective was to establish a cost-effective method for environmental enrichment, utilizing the liver as a representative organ to assess potential metabolic changes in response to differing enrichment levels. METHODS We conducted a six-month study involving 24 male Sprague Dawley rats, randomly assigned to four environmental enrichment groups. Two groups were housed in standard cages, while the others were placed in modified rabbit cages. Half of the groups received weekly playtime in an activity focused rat housing unit. We evaluated hormone levels, playtime behavior, and subjective handling experience. Additionally, liver tissue proteomic analysis was performed. RESULTS Initial corticosterone levels and those after 3 and 6 months showed no significant differences. Yet, testosterone levels were lower in the control group by the end of the study (p = 0.007). We observed 1871 distinct proteins in liver tissue, with 77% being common across groups. In gene ontology analysis, no specific pathways were overexpressed. In semiquantitative analysis, we observed differences in proteins associated in lipid metabolism such as Apolipoprotein A-I and Acyl-CoA 6-desaturase, which were lower in the control group (p = 0.024 and p = 0.009). Rats in the intervention groups with weekly playtime displayed the least amount of reported distress during inspection or upon room entry and were less prone to accepting treats. Removing animals from their enclosure was most effortless for those in the large cage group. Over time, there was a decrease in conflicts among rats that interacted only twice weekly during playpen time. DISCUSSION In summary, refining husbandry practices for aging rats is both simple and budget-friendly, with no apparent adverse effects on stress levels, animal development, or relevant metabolic changes in the liver.

Abstract
We review the descriptive epidemiology of Parkinson disease (PD). PD is a prevalent neurologic disorder in high Socio-Demographic Index (SDI) nations with rising prevalence in low and middle SDI nations. PD became a prevalent disorder in high SDI nations during the 20th century. Population growth, population aging, and increased disease duration are major drivers of rising PD prevalence. Exposure to industrial toxicants may also be a contributor to rising PD prevalence. PD is an age-related disorder with incidence likely peaking in the 8th decade of life and prevalence in the 9th decade of life. PD is notable for significant sex difference in PD risk with greater risk in men. There may be ancestral differences in PD prevalence and risk. PD is associated with moderately increased mortality though this may be underestimated. Despite significant research, there is considerable uncertainty about basic features of PD epidemiology.

Abstract
The epidemiology of Parkinson's disease shows marked variations in time, geography, ethnicity, age, and sex. Internationally, prevalence has increased over and above demographic changes. There are several potential reasons for this increase, including the decline in other competing causes of death. Whether incidence is increasing, especially in women or in many low-income and middle-income countries where there is a shortage of high-quality data, is less certain. Parkinson's disease is more common in older people and men, and a variety of environmental factors have been suggested to explain why, including exposure to neurotoxic agents. Within countries, there appear to be ethnic differences in disease risk, although these differences might reflect differential access to health care. The cause of Parkinson's disease is multifactorial, and involves genetic and environmental factors. Both risk factors (eg, pesticides) and protective factors (eg, physical activity and tendency to smoke) have been postulated to have a role in Parkinson's disease, although elucidating causality is complicated by the long prodromal period. Following the establishment of public health strategies to prevent cardiovascular diseases and some cancers, chronic neurodegenerative diseases such as Parkinson's disease and dementia are gaining a deserved higher priority. Multipronged prevention strategies are required that tackle population-based primary prevention, high-risk targeted secondary prevention, and Parkinson's disease-modifying therapies for tertiary prevention. Future international collaborations will be required to triangulate evidence from basic, applied, and epidemiological research, thereby enhancing the understanding and prevention of Parkinson's disease at a global level.

Abstract
OBJECTIVE To directly compare the effect of incident age 68+ traumatic brain injury (TBI) on the risk of diagnosis of clinical Alzheimer's disease (AD) in the general population of older adults, and between male veterans and nonveterans; to assess how this effect changes with time since TBI. SETTING AND PARTICIPANTS Community-dwelling traditional Medicare beneficiaries 68 years or older from the Health and Retirement Study (HRS). DESIGN Fine-Gray models combined with inverse-probability weighting were used to identify associations between incident TBI, post-TBI duration, and TBI treatment intensity, with a diagnosis of clinical AD dementia. The study included 16 829 older adults followed over the 1991-2015 period. For analyses of veteran-specific risks, 4281 veteran males and 3093 nonveteran males were identified. Analysis of veteran females was unfeasible due to the age structure of the population. Information on occurrence(s) of TBI, and onset of AD and risk-related comorbidities was constructed from individual-level HRS-linked Medicare claim records while demographic and socioeconomic risk factors were based on the survey data. RESULTS Later-life TBI was strongly associated with increased clinical AD risk in the full sample (pseudo-hazard ratio [HR]: 3.22; 95% confidence interval [CI]: 2.57-4.05) and in veteran/nonveteran males (HR: 5.31; CI: 3.42-7.94), especially those requiring high-intensity/duration care (HR: 1.58; CI: 1.29-1.91). Effect magnitude decreased with time following TBI (HR: 0.72: CI: 0.68-0.80). CONCLUSION Later-life TBI was strongly associated with increased AD risk, especially in those requiring high-intensity/duration care. Effect magnitude decreased with time following TBI. Univariate analysis showed no differences in AD risk between veterans and nonveterans, while the protective effect associated with veteran status in Fine-Gray models was largely due to differences in demographics, socioeconomics, and morbidity. Future longitudinal studies incorporating diagnostic procedures and documentation quantifying lifetime TBI events are necessary to uncover pathophysiological mediating and/or moderating mechanisms between TBI and AD.

Abstract
BACKGROUND AND PURPOSE Idiopathic Parkinson's disease (IPD) is a progressive neurodegenerative disorder that is strongly associated with age. The aim of the present study was to describe current sex- and age-specific trends and regional differences in the incidence of IPD diagnosed in older people in Germany. METHODS This study was based on nationwide outpatient claims and drug prescription data from the German Statutory Health Insurance, covering approximately 87% of the general population. We conducted a cohort study in patients aged 50 years or older with observation time of at least 4 years. To assess the robustness of nationwide annual IPD incidence trends from 2013 to 2019, three case definitions with varying levels of stringency regarding coded outpatient diagnoses and drug prescriptions were applied. RESULTS In 2019, the population at risk comprised 30,575,726 persons. Using the primary and most specific case definition, annual age- and sex-standardized cumulative IPD incidence decreased stepwise from 137 (2013) to 106 (2019) new cases per 100,000 persons. The decline in incidence was seen in both sexes, in all age groups and in the majority of German regions. The relative decrease (2013-2019) in the annual age- and sex-standardized IPD incidence varied from 23% to 28% among case definitions. CONCLUSION Our findings indicate a nationwide decline in the age- and sex-standardized incidence of IPD from 2013 to 2019 in Germany. This trend was consistent using different case definitions. Further research is needed to elucidate the factors underlying this trend.

Abstract
Introduction We aimed to investigate the incidence of Parkinson's disease (PD) by age and year for each sex as well as the modifiable risk factors for PD. Using data from the Korean National Health Insurance Service, 938,635 PD and dementia-free participants aged ≥40 years who underwent general health examinations were followed to December 2019. Methods We analyzed the PD incidence rates according to age, year and sex. To investigate the modifiable risk factors for PD, we used the Cox regression model. Additionally, we calculated the population-attributable fraction to measure the impact of the risk factors on PD. Results During follow-up, 9,924 of the 938,635 (1.1%) participants developed PD. The incidence of PD increased continuously from 2007 to 2018, reaching 1.34 per 1,000 person-years in 2018. The incidence of PD also increases with age, up to 80 y. Presence of hypertension (SHR = 1.09, 95% CI 1.05 to 1.14), diabetes (SHR = 1.24, 95% CI 1.17 to 1.31), dyslipidemia (SHR = 1.12, 95% CI 1.07 to 1.18), ischemic stroke (SHR = 1.26, 95% CI 1.17 to 1.36), hemorrhagic stroke (SHR = 1.26, 95% CI 1.08 to 1.47), ischemic heart disease (SHR = 1.09, 95% CI 1.02 to 1.17), depression (SHR = 1.61, 95% CI 1.53 to 1.69), osteoporosis (SHR = 1.24, 95% CI 1.18 to 1.30), and obesity (SHR = 1.06, 95% CI 1.01 to 1.10) were independently associated with a higher risk for PD. Discussion Our results highlight the effect of modifiable risk factors for PD in the Korean population, which will help establish health care policies to prevent the development of PD.

Abstract
Average life expectancies have lengthened across human history. As a result, there is an increased need to care for a greater number of individuals experiencing common age-related declines in health. This has helped to spur a rapidly increasing focus on understanding "health span", the portion of the life-course spent functionally healthy. Yet to penetrate the science of health span, however, is a topic which seems fundamental to the ability to age in functional and healthy ways, and has received considerable attention in other fields. As more of the population ages, the risk of exposure to abuse and neglect among older citizens not only rises, but can manifest as both cause and effect of declining health span. Among our goals here is to make a case for including this subject among the other central components of health span science. In so doing, we also outline reasons why quantitative genetic designs using samples of twins can be a versatile tool for improving causal inference when studying maltreatment among older persons specifically, but also on a range of other health span topics in general.

Abstract
Purpose Elderly patients are associated with a higher risk of nosocomial cross infection during the COVID-19 pandemic. Providing medical services and primary care for elderly patients is a worldwide challenge. A new telegeriatrics system was established to provide medical services and primary care for elderly patients treated by family physicians. This study aimed to describe the operation mechanism of the new system and investigate the demands of telegeriatrics medical services for elderly patients treated by family physicians during the COVID-19 pandemic. Methods A total of 1,353 elderly patients (aged≥60) treated by family physicians were enrolled. The proportion of the top 10 diseases of elderly patients applying the new system was analyzed. Differences in main diseases between elderly patients applying telegeriatrics medical services and outpatients in hospitals were compared. Differences between the new telegeriatrics system in our study and telemedicine systems of other studies in other countries were analyzed. Results Constituent ratios of chronic kidney disease, type 2 diabetes mellitus, and coronary heart disease have the highest rate in elderly patients applying the new telegeriatrics system. Digestive diseases, cardiovascular diseases, and neurology diseases were the top three diseases of elderly outpatients. Conclusion This is the first time that a new telegeriatrics system has been applied to provide medical services for elderly patients treated by family physicians during the COVID-19 pandemic. Chronic kidney disease, Type 2 diabetes mellitus, and coronary heart disease were found to be the top three diseases of elderly patients applying telegeriatrics medical services during the COVID-19 pandemic, which were different from the outpatients in general hospitals. The new telegeriatrics system guarantees elderly patients get equal rights to medical services. Results will provide a basis for the government health administrative department to formulate new telegeriatrics policies for elderly patients.

Abstract
Parkinson's disease (PD) has the fastest rising prevalence of all neurodegenerative diseases worldwide. However, it is unclear whether its incidence has increased after accounting for age and changes in diagnostic patterns in the same population. We conducted a cohort study in individuals aged ≥50 years within a large UK primary care database between January 2006 and December 2016. To account for possible changes in diagnostic patterns, we calculated the incidence of PD using four case definitions with different stringency derived from the combination of PD diagnosis, symptoms, and treatment. Using the broadest case definition, the incidence rate (IR) per 100,000 person years at risk (PYAR) was 149 (95% CI 143.3-155.4) in 2006 and 144 (95% CI 136.9-150.7) in 2016. In conclusion, the incidence of PD in the UK remained stable between 2006 and 2016, when accounting for age and diagnostic patterns, suggesting no major change in underlying risk factors for PD during this time period in the UK.

Abstract
BACKGROUND Understanding the dynamics of epidemiologic trends in Alzheimer's disease (AD) and related dementias (ADRD) and their epidemiologic causes is vital to providing important insights into reducing the burden associated with these conditions. OBJECTIVE To model the time trends in age-adjusted AD/ADRD prevalence and incidence-based mortality (IBM), and identify the main causes of the changes in these measures over time in terms of interpretable epidemiologic quantities. METHODS Trend decomposition was applied to a 5%sample of Medicare beneficiaries between 1991 and 2017. RESULTS Prevalence of AD was increasing between 1992 and 2011 and declining thereafter, while IBM increased over the study period with a significant slowdown in its rate of growth from 2011 onwards. For ADRD, prevalence and IBM increased through 2014 prior to taking a downwards turn. The primary determinant responsible for declines in prevalence and IBM was the deceleration in the increase and eventual decrease in incidence rates though changes in relative survival began to affect the overall trends in prevalence/IBM in a noticeable manner after 2008. Other components showed only minor effects. CONCLUSION The prevalence and IBM of ADRD is expected to continue to decrease. The directions of these trends for AD are not clear because AD incidence, the main contributing component, is decreasing but at a decreasing rate suggesting a possible reversal. Furthermore, emerging treatments may contribute through their effects on survival. Improving ascertainment of AD played an important role in trends of AD/ADRD over the 1991-2009/10 period but this effect has exhausted itself by 2017.

A randomized controlled feasibility study as part of the PROCARE project. Aging Clin Exp Res 2021; 33:943-956. [PMID: 32537707 DOI: 10.1007/s40520-020-01615-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Accepted: 05/28/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND A multi-component training program holds promises for the elderly, but still has to be tested on its feasibility and effect in nursing homes. AIMS The aim of this study was (1) to design a multi-component training program which improves physical functioning and psychosocial wellbeing and (2) to evaluate the feasibility of this intervention in nursing home residents. METHODS This study is a two-arm, stratified-randomized controlled feasibility trail. Twenty-four nursing home residents (aged 83.7 ± 6.4, 21 women) were divided into an intervention and a waiting-list control group. The intervention group completed a multi-component training (including dual-task, dynamic balance, endurance and strength exercises) for 16 weeks (twice per week for 45-60 min). Primary outcomes were lower extremity functionality (SPPB), gait performance (GAITRite), health-related quality of life (SF-12) as well as life satisfaction (SWLS). RESULTS Life satisfaction (SWLS) and physical functioning (SPPB) increased in the intervention group after training whereas the control group showed a decrease. Gait parameters could only be analyzed for n = 5 participants of the intervention group and n = 2 of the control group and showed no time differences for the intervention group. The mean number of participants was 12.5 ± 1.9 per session (attendance ranged between 66% and 90%). CONCLUSION A multi-component training seems (1) to lead to clinically relevant improvements in physical functioning as well as in psychosocial wellbeing and (2) to be feasible and well accepted in nursing home residents. Nevertheless, the complexity and progression of the program as well as the testing protocol have to be adapted. Further research should test the effectiveness of this adapted program in a larger sample size.

Abstract
Tauopathies are neurodegenerative disorders with increasing incidence and still without cure. The extensive time required for development and approval of novel therapeutics highlights the need for testing and repurposing known safe molecules. Since doxycycline impacts α-synuclein aggregation and toxicity, herein we tested its effect on tau. We found that doxycycline reduces amyloid aggregation of the 2N4R and K18 isoforms of tau protein in a dose-dependent manner. Furthermore, in a cell free system doxycycline also prevents tau seeding and in cell culture reduces toxicity of tau aggregates. Overall, our results expand the spectrum of action of doxycycline against aggregation-prone proteins, opening novel perspectives for its repurposing as a disease-modifying drug for tauopathies.

Abstract
BACKGROUND AND PURPOSE Due to global ageing, more people will suffer from hip fracture in the future, and many will be left with permanent physical impairments. The care burden for people post hip fracture is high. The aim of this study is to measure longitudinal changes in physical activity levels and fear of falling in people after hip fracture who return home after inpatient rehabilitation. METHODS Longitudinal observational study. Participants were recruited from three rehabilitation centres in Victoria, Australia. Self-reported fear of falling (Short Falls Efficacy Scale - International) and physical activity levels (Human Activity Profile - Adjusted Activity Score and Frenchay Activity Index) were assessed at 2 weeks, 3 and 6 months after discharge. Mobility (walking speed) and balance (Timed Up-and-Go test and Step Test) were measured at discharge from rehabilitation. RESULTS Thirty-four participants (mean age: 82 years [SD 8]; 62% female) with unilateral hip fracture were recruited. Participants had moderately impaired balance and mobility at discharge compared to age-matched normative data; they were all discharged with a walking aid and were 40% slower in their walking speed. Participants had increased fear of falling and reduced physical activity 2 weeks after discharge, which improved significantly (p < 0.01) over the following 6 months, but scores were still lower than the normative values. At 6 months, participants also had moderate to high levels of fear of falling and were less active than the general population of similar age. DISCUSSION Although fear of falling and physical activity improved in the 6 months following discharge, both remained negatively affected compared to normative data. Rehabilitation post hip fracture should include routine assessment of fear of falling as a potential barrier for return of physical activities.

Abstract
OBJECTIVE The purpose of this study was to explore the prevalence of thyroid nodules (TN) and metabolic syndrome (MS) and to analyze the correlation between TN and the components of MS. METHODS A total of 1526 subjects were divided into two groups: a TN group and a non-thyroid nodules (NTN) group. The height, weight, blood pressure, fasting blood glucose level, fasting plasma insulin level, serum lipid profile, uric acid level, serum thyroid-stimulating hormone (TSH) level, free triiodothyronine (FT3) level, and free thyroxine (FT4) level of each patient were measured. Insulin resistance (IR) was estimated by homeostasis model assessment of insulin resistance (HOMA-IR). Fatty liver and TN were detected by color Doppler ultrasonography. RESULTS (i) The overall prevalence of TN was 39.5%; it was significantly higher in women than in men (P < 0.01) and progressively increased with age in both sexes. (ii) The overall prevalence of MS was 25.6%; it was significantly higher in men than in women (P < 0.01) and progressively increased with age in both sexes. (iii) FT3 was significantly lower in the TN group than in the NTN group (P < 0.01). (iv) BMI, triglycerides, and HOMA-IR were higher in the TN group than in the NTN group (P < 0.05). (v) The existence of TN was significantly associated with overweight/obesity (OR = 1.03, 95% CI = 1.024-1.089), and with insulin resistance (IR) (OR = 1.98, 95% CI = 1.645-2.368), after adjusting for age and sex. CONCLUSIONS The prevalence of thyroid nodules and metabolic syndrome in the Nanchang area increases with age, and overweight/obesity and IR in patients are associated with thyroid nodules.

Abstract
Background: Multiple chronic conditions (MCCs) are associated with increased intensity of end-of-life (EOL) care, but their effect is not well explored in patients with cancer. Objective: We examined EOL health care intensity and advance care planning (ACP) documentation to better understand the association between MCCs and these outcomes. Design: Retrospective cohort study. Setting/Subjects: Patients aged 18+ years at UW Medicine who died during 2010-2017 with poor prognosis cancer, with or without chronic liver disease, chronic pulmonary disease, coronary artery disease, dementia, diabetes with end-stage organ damage, end-stage renal disease, heart failure, or peripheral vascular disease. Measurements: ACP documentation 30+ days before death, in-hospital death, and inpatient or intensive care unit (ICU) admission in the last 30 days. We performed logistic regression for outcomes. Results: Of 15,092 patients with cancer, 10,596 (70%) had 1+ MCCs (range 1-8). Patients with cancer and heart failure had highest odds of hospitalization (odds ratio [OR] 1.67, 95% confidence interval [CI] 1.46-1.91), ICU admission (OR 2.06, 95% CI 1.76-2.41), or in-hospital death (OR 1.62, 95% CI 1.43-1.84) versus patients with cancer and other conditions. Patients with ACP 30+ days before death had lower odds of in-hospital death (OR 0.65, 95% CI 0.60-0.71), hospitalization (OR 0.67, 95% CI 0.61-0.74), or ICU admission (OR 0.71, 95% CI 0.64-0.80). Conclusions: Patients with ACP 30+ days before death had lower odds of high-intensity EOL care. Further research needs to explore how to best use ACP to ensure patients receive care aligned with patient and family goals for care.

Abstract
PURPOSE The present study aims to investigate the prevalence of single and multiple thyroid nodules and its association with metabolic diseases in subjects who participated in the heath examination in China. METHODS This is a cross-sectional study. The participants who attend the physical examination at the Health Management Center of Southwest Hospital, Army Military Medical University, between January 2014 and December 2018, were included. Thyroid nodules were diagnosed by thyroid ultrasound. Multivariable logistic regression was used to investigate the association between metabolic diseases and nodular thyroid disease. RESULTS A total of 9,146 subjects were included in this study; of them, 2,961 were diagnosed with thyroid nodules, with a prevalence of 32.4%. The prevalence in women was significantly higher than that in men (45.2% vs 26.0%; χ 2 = 339.56, P < 0.001), and the prevalence was gradually increased with age (Z = 20.05, P < 0.001), and the prevalence was gradually increased with age (. CONCLUSIONS The prevalence of thyroid nodules was relatively high. Age, female gender, and diabetes are positively associated with nodular thyroid disease. High LDL cholesterolemia is more likely to be associated with multiple thyroid sarcoidosis.

Abstract
BACKGROUND Kidney transplant recipients with a history of a pre-transplant malignancy (pre-TM) have an increased risk of post-transplant malignancies (post-TM) and suspected inferior long-term outcomes. No large database studies have examined modern day trends and outcomes in this patient population compared with those without a pre-TM. STUDY DESIGN The United Network for Organ Sharing (UNOS) database was queried for primary adult kidney transplant recipients with pre-TM. Outcomes were compared in patients with and without pre-TM from 2004 to 2016 using multivariable Cox proportional hazard analyses (n = 170,684). RESULTS The rate of kidney transplants in patients with pre-TM increased from <1% of all kidney transplants in 1994 (n = 77) to 8.3% in 2016 (n = 1,329). Pre-TM was associated with development of post-TM (hazard ratio [HR] 1.77 CI 1.68, 1.86), all cause (HR 1.22 CI 1.18, 1.27), and death-censored graft failure (HR 1.08 CI 1.02, 1.15) between 2004 and 2016. The 5-year all cause graft failure rate was 28% for pre-TM patients and 22% for non-pre-TM patients. Pre-TM was associated with decreased patient survival (5-year 80% vs 88% and HR 1.23 CI 1.18, 1.28). Of the deceased, more pre-TM patients died of malignancy (19% vs 11%). CONCLUSIONS Increasing numbers of patients with pre-TM are undergoing kidney transplantation. This analysis indicates that patients with pre-TM are at increased risk of post-TM, graft loss, and decreased overall survival. The study's limitations highlight the need for collaborative database development between transplant and cancer registries to better define the inter-relationship between a pre-TM and cancer survivorship vs freedom from prolonged dialysis.

Abstract
BACKGROUND The lack of adequate and detailed epidemiological data of Parkinson's disease (PD), especially in Asia, is a barrier to future disease burdens and the prospect of effective public health plans. This study aimed to investigate temporal trends in the incidence and prevalence of PD in South Korea from 2010 to 2015, based on uniform diagnostic criteria. METHODS This study examined all PD patients registered in a South Korean national registry database of more than 50 million individuals. We analyzed the incidence and prevalence of PD according to age, gender, and region. RESULTS The annual incidence of PD was between 22.4-27.8 cases per 100,000 individuals. During the 6-year study period, there were 73,726 new PD patients, 42.3% of whom were men. The standardized incidence of PD increased over time in men but remained constant in women until 2013 but began to increase in 2014. The female-to-male ratio in the incidence of PD was 1.4:1 while the female-to-male ratio in the prevalence of PD was 1.6:1. The age- and gender-standardized prevalence of PD increased from 115.9 cases per 100,000 individuals in 2010 to 139.8 cases per 100,000 individuals in 2015. From 2014, the incidence and prevalence of PD peaked in individuals aged between 80 and 89 years in both men and women. Regional analysis also showed an increased prevalence of PD in all regions of Korea. CONCLUSIONS The incidence and prevalence of PD in Korea were higher in women and increased gradually from 2010 to 2015. The findings may contribute to epidemiological studies of PD in Asia, and may provide clues on risk factors for PD.

Abstract
Background The frequency of thyroid nodules (TNs) has increased rapidly in recent decades. We established a simple, effective model to predict TN occurrence by a large-scale comparative analysis of the Chinese population. Subjects and methods A total of 13,307 subjects were included to screen risk factors between the case group (TN+) and the control group (TN-) by univariate and multivariate analyses. A simple prediction model formed by a subset of five factors was established. The optimal index points for predicting the prevalence of TNs, the model discriminatory power and the association of the model with the size of TNs were assessed. Results Age at diagnosis ≥45 years, female sex, body mass index (BMI) ≥24 kg/m2, hypertension, antithyroglobulin antibody (TGAB) ≥16.5 IU/mL were independently related to an increased risk of TNs. The cutoff value of 4 points was found to be the best prediction for the prevalence of TNs in the current study, and the model had better discriminatory power than other single independent predictors. In addition, a positive correlation was also found between the index points and the diameter of TNs. Conclusion Based on our prediction model, thyroid high-resolution ultrasound and associated laboratory tests may be necessary for patients with index points ≥4 due to a higher prevalence of thyroid nodules.

Abstract
Neurological disorders are now the leading source of disability globally, and the fastest growing neurological disorder in the world is Parkinson disease. From 1990 to 2015, the number of people with Parkinson disease doubled to over 6 million. Driven principally by aging, this number is projected to double again to over 12 million by 2040. Additional factors, including increasing longevity, declining smoking rates, and increasing industrialization, could raise the burden to over 17 million. For most of human history, Parkinson has been a rare disorder. However, demography and the by-products of industrialization have now created a Parkinson pandemic that will require heightened activism, focused planning, and novel approaches.

Abstract
OBJECTIVE To assess what proportions of studies reported increasing, stable, or declining trends in the incidence of diagnosed diabetes. DESIGN Systematic review of studies reporting trends of diabetes incidence in adults from 1980 to 2017 according to PRISMA guidelines. DATA SOURCES Medline, Embase, CINAHL, and reference lists of relevant publications. ELIGIBILITY CRITERIA Studies of open population based cohorts, diabetes registries, and administrative and health insurance databases on secular trends in the incidence of total diabetes or type 2 diabetes in adults were included. Poisson regression was used to model data by age group and year. RESULTS Among the 22 833 screened abstracts, 47 studies were included, providing data on 121 separate sex specific or ethnicity specific populations; 42 (89%) of the included studies reported on diagnosed diabetes. In 1960-89, 36% (8/22) of the populations studied had increasing trends in incidence of diabetes, 55% (12/22) had stable trends, and 9% (2/22) had decreasing trends. In 1990-2005, diabetes incidence increased in 66% (33/50) of populations, was stable in 32% (16/50), and decreased in 2% (1/50). In 2006-14, increasing trends were reported in only 33% (11/33) of populations, whereas 30% (10/33) and 36% (12/33) had stable or declining incidence, respectively. CONCLUSIONS The incidence of clinically diagnosed diabetes has continued to rise in only a minority of populations studied since 2006, with over a third of populations having a fall in incidence in this time period. Preventive strategies could have contributed to the fall in diabetes incidence in recent years. Data are limited in low and middle income countries, where trends in diabetes incidence could be different. SYSTEMATIC REVIEW REGISTRATION Prospero CRD42018092287.

Abstract
BACKGROUND With the changes in environmental, medical technique, population structure and national health projects, human mortality rates have undergone great changes all over the world. According to "World Health Statistics 2016: Monitoring Health for the SDGs (Sustainable Development Goals)", we can draw a globally vision about life expectancy and cause of death; also, significant inequality still persists within and among countries. This study was designed to research into the trend of mortality pattern in China, evaluate the disparities of age-specific and disease-specific mortality rates between male and female, and provides a scientific basis for further prevention strategies and policies design. METHODS Data from the Chinese Disease Surveillance Points system were used to calculate crude and age-adjusted death rates, annual percent changes (APC) for men and women during 2004 to 2016. Age-standardized mortality rates (ASMR) were performed through the direct method with the World Health Organization's World Standard Population. APC, according to log linear model, was adopted to describe the mortality rate trend. The χ2 test was used to compare differences between age-specific and cause-specific mortality rates of men and women. Data analysis and figures were completed by R software. RESULTS The mortality rates of men and women have decreased significantly (P < 0.05) during 2004-2016, and the APC were1.98 and 2.45%, respectively. In 2016, the crude mortality rate (CMR) and ASMR in all causes of death were 658.50 and 490.28 per 100,000 per year, respectively. The 5 leading causes of death were malignant neoplasm, cerebrovascular disease, heart disease, COPD, and accidental injury. The mortality rates of men were higher than that of women in all age groups. CONCLUSIONS There are severe health gaps and disparities between male and female, and the chronic non-communicable diseases continue to be a serious health threat to Chinese residents.

Abstract
PURPOSE The main purpose of this study was to determine whether there were temporal differences in the rates of first stroke hospitalizations and 30-day mortality after stroke between black and white Medicare enrollees. METHODS We used a 20% sample of Medicare beneficiaries aged 65 years or older and described the annual rate of first hospitalization for ischemic and hemorrhagic strokes from years 1988 to 2013, as well as 30-day mortality after stroke hospitalization. We used linear tests of trend to determine whether stroke rates changed over time, and tested the interaction term between race and year to determine whether trends differed by race. RESULTS We identified 1,009,057 incident hospitalizations for ischemic strokes and 147,817 for hemorrhagic strokes. Annual stroke hospitalizations decreased significantly over time for both blacks and whites, and in both stroke subtypes (P-values for all trend <0.001). Reductions in stroke rates were comparable between blacks and whites: among men, the odds ratio for the interaction term for race by year was 1.008 [95% confidence interval (CI), 1.004-1.012] for ischemic and 1.002 (95% CI, 0.999-1.004) for hemorrhagic; for women, it was 1.000 (95% CI, 0.997-1.004) for ischemic and 1.003 (95% CI, 1.001-1.006) for hemorrhagic. Both black men and women experienced greater improvements over time in terms of 30-day mortality after strokes. CONCLUSIONS Rates of incident hospitalizations for ischemic and hemorrhagic strokes fell significantly over a 25-year period for both black and white Medicare enrollees. Black men and women experienced greater improvements in 30-day mortality after both ischemic and hemorrhagic stroke.

Abstract
PURPOSE To evaluate the development in the use of medications associated with an increased risk of developing osteoporosis over the time period from 1999 to 2016. METHODS We extracted data on total sale, sales rate and usage rate for the medications of interest from www.medstat.dk, which is an online, open-source database reporting the monthly sale of both over-the-counter and prescription-based medications in Denmark. The dataset covers both the primary and secondary health sectors. RESULTS Most medications exhibited an increasing use from 1999 to 2016, though some had stable (e.g. glucocorticoids) or declining use. Notably, some medications showed widespread and increasing use, including proton pump inhibitors (PPI), selective serotonine reuptake inhibitors (SSRI) and venlafaxine. For PPI, sales rates increased by 461% from 1999 to 2016, with 9% of men and 11.4% of women filling at least one prescription in 2016. The use of SSRI and venlafaxine increased by 114% and 613%, respectively. This was more pronounced in women and for SSRI also in the elderly (80+ years). The sale of aromatase inhibitors was moderate (1-10 DDD per 1000 capita per day) in 2016, yet grew by 2400% from 1999, almost exclusively in women aged 80 years or older. CONCLUSION We found a trend of increasing use from 1999 to 2016 of most medications with a potential for causing osteoporosis, often most pronounced in fracture risk groups (postmenopausal women and/or in the elderly). This may play a clinically relevant role in both current and future causality of osteoporosis.

Abstract
ABSTRACT:Objectives:We assessed trends in the incidence, prevalence, and post-diagnosis mortality of parkinsonism in Ontario, Canada over 18 years. We also explored the influence of a range of risk factors for brain health on the trend of incident parkinsonism.Methods:We established an open cohort by linking population-based health administrative databases from 1996 to 2014 in Ontario. The study population comprised residents aged 20–100 years with an incident diagnosis of parkinsonism ascertained using a validated algorithm. We calculated age- and sex-standardized incidence, prevalence, and mortality of parkinsonism, stratified by young onset (20–39 years) and mid/late onset (≥40 years). We assessed trends in incidence using Poisson regression, mortality using negative binomial regression, and prevalence of parkinsonism and pre-existing conditions (e.g., head injury) using the Cochran–Armitage trend test. To better understand trends in the incidence of mid/late-onset parkinsonism, we adjusted for various pre-existing conditions in the Poisson regression model.Results:From 1996 to 2014, we identified 73,129 incident cases of parkinsonism (source population of ∼10.5 million), of whom 56% were male, mean age at diagnosis was 72.6 years, and 99% had mid/late-onset parkinsonism. Over 18 years, the age- and sex-standardized incidence decreased by 13.0% for mid/late-onset parkinsonism but remained unchanged for young-onset parkinsonism. The age- and sex-standardized prevalence increased by 22.8%, while post-diagnosis mortality decreased by 5.5%. Adjustment for pre-existing conditions did not appreciably explain the declining incidence of mid/late-onset parkinsonism.Conclusion:Young-onset and mid/late-onset parkinsonism exhibited differing trends in incidence over 18 years in Ontario. Further research to identify other factors that may appreciably explain trends in incident parkinsonism is warranted.

Abstract
Aging is an inevitable biological process characterized by the loss of functional capacity and associated with changes in all phases of pharmacokinetic processes. Naringin, a dietary flavanone glycoside, has been proved to be beneficial for the treatment of multiple age-associated chronic diseases. To date, the pharmacokinetic processes of naringin in aged individuals are still unknown. Thus, a rapid resolution liquid chromatography tandem triple quadrupole mass spectrometry (RRLC-QQQ-MS/MS) method was established for the determination of naringin and its metabolite naringenin in rat plasma, urine, feces, and tissue homogenate. The pharmacokinetic parameters were calculated and a higher exposure of naringin and naringenin were observed in aged rats. Naringin and naringenin were mostly distributed in gastrointestinal tract, liver, kidney, lung, and trachea. Furthermore, a total of 39 flavonoid metabolites (mainly glucuronides and sulfates) and 46 microbial-derived phenolic catabolites were screened with ultra-fast liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UFLC-Q-TOF-MS/MS). Naringenin, hippuric acid, and 3-(4'-hydroxyphenyl)propionic acid were predominated metabolites. This study systemically investigated the pharmacokinetics, tissue distribution, metabolism, and excretion of naringin in aged rats, revealing age- and gender-related changes in the in vivo behavior of naringin. These results would be helpful for the interpretation of pharmacokinetics and pharmacodynamics of naringin in aged population.

Abstract
The study objective was to estimate secular trends in the overall incidence rate (IR) and prevalence rate (PR) of rheumatoid arthritis (RA); and subgroup-specific IR and PR by race, ethnicity, and sex in a multi-ethnic population of a large integrated health care delivery system. An ecological study was conducted within the adult population of Kaiser Permanente Southern California health plan. From January 1995 up to and including December 2014, annual IR and PR were calculated separately by race, ethnicity, sex and pooled overall. Depending on the stationarity of each ecological series, annual percentage change in IR and PR was evaluated using auto-regressive integrated moving average models. Average overall IR was 53 [95% confidence interval (CI) 46, 61] per 100,000 person-years. The overall as well as subgroup-specific annual IR of RA were unchanged from 1995 to 2014. In 1995, the overall PR of RA was 59 (44, 74) per 100,000 person-years which increased by 14% (7%, 21%) annually thereafter. The increase in PR in Caucasians was lower as compared to African American, Asian and other race (13% vs 15%, 15%, and 18%, respectively). Compared to non-Hispanic ethnicity, the increase in PR among Hispanic was higher (17% vs 14%). Over the past 2 decades, while the incidence of RA was unchanged, the prevalence had increased significantly overall as well as within every subgroup of race, ethnicity, and sex.

Abstract
Background Neurological disorders are now the leading source of disability globally, and ageing is increasing the burden of neurodegenerative disorders, including Parkinson's disease. We aimed to determine the global burden of Parkinson's disease between 1990 and 2016 to identify trends and to enable appropriate public health, medical, and scientific responses. Methods Through a systematic analysis of epidemiological studies, we estimated global, regional, and country-specific prevalence and years of life lived with disability for Parkinson's disease from 1990 to 2016. We estimated the proportion of mild, moderate, and severe Parkinson's disease on the basis of studies that used the Hoehn and Yahr scale and assigned disability weights to each level. We jointly modelled prevalence and excess mortality risk in a natural history model to derive estimates of deaths due to Parkinson's disease. Death counts were multiplied by values from the Global Burden of Disease study's standard life expectancy to compute years of life lost. Disability-adjusted life-years (DALYs) were computed as the sum of years lived with disability and years of life lost. We also analysed results based on the Socio-demographic Index, a compound measure of income per capita, education, and fertility. Findings In 2016, 6·1 million (95% uncertainty interval [UI] 5·0–7·3) individuals had Parkinson's disease globally, compared with 2·5 million (2·0–3·0) in 1990. This increase was not solely due to increasing numbers of older people, because age-standardised prevalence rates increased by 21·7% (95% UI 18·1–25·3) over the same period (compared with an increase of 74·3%, 95% UI 69·2–79·6, for crude prevalence rates). Parkinson's disease caused 3·2 million (95% UI 2·6–4·0) DALYs and 211 296 deaths (95% UI 167 771–265 160) in 2016. The male-to-female ratios of age-standardised prevalence rates were similar in 2016 (1·40, 95% UI 1·36–1·43) and 1990 (1·37, 1·34–1·40). From 1990 to 2016, age-standardised prevalence, DALY rates, and death rates increased for all global burden of disease regions except for southern Latin America, eastern Europe, and Oceania. In addition, age-standardised DALY rates generally increased across the Socio-demographic Index. Interpretation Over the past generation, the global burden of Parkinson's disease has more than doubled as a result of increasing numbers of older people, with potential contributions from longer disease duration and environmental factors. Demographic and potentially other factors are poised to increase the future burden of Parkinson's disease substantially. Funding Bill & Melinda Gates Foundation.

Abstract
AIMS To identify how efforts to control the diabetes epidemic and the resulting changes in diabetes mellitus, type II (T2D) incidence and survival have affected the time-trend of T2D prevalence. METHODS A newly developed method of trend decomposition was applied to a 5% sample of Medicare administrative claims filed between 1991 and 2012. RESULTS Age-adjusted prevalence of T2D for adults age 65+ increased at an average annual percentage change of 2.31% between 1992 and 2012. Primary contributors to this trend were (in order of magnitude): improved survival at all ages, increased prevalence of T2D prior to age of Medicare eligibility, decreased incidence of T2D after age of Medicare eligibility. CONCLUSIONS Health services supported by the Medicare system, coupled with improvements in medical technology and T2D awareness efforts provide effective care for individuals age 65 and older. However, policy maker attention should be shifted to the prevention of T2D in younger age groups to control the increase in prevalence observed prior to Medicare eligibility.

Abstract
Public knowledge of the anatomical "self" is lacking and evidence points towards a growing need for anatomy education to the wider public. The public were offered the opportunity to learn human anatomy and complete an anatomical knowledge survey afterwards. Sixty-three participants volunteered to attempt to place 20 anatomical structures on a blank human body template. Responses were scored independently and then collated. A mixed effects logistic model was used to examine any associations with participants' as a random effect and all other factors as fixed effects. Results showed a statistically significant quadratic trend with age. Participants in health-related employment scored significantly higher than those not in health-related employment. There was a significant interaction between gender and organ type with males scoring higher than females in identifying muscles, but not in identifying internal organs. The current study demonstrates the general public's eagerness to learn anatomy despite their limited knowledge of the human body, and the need for widening participation. Furthermore, it raises an awareness of the anatomical literacy needs of the general public, especially in school children and young adults. Furthermore, it emphasizes the value of health literacy as a focus in undergraduate medical education. Anatomy literacy appears to be neglected, and this experience provides an example of a possible mode of public engagement in anatomy.

Abstract
Objective: The aim of this study was to examine the possibility that type 2 diabetes and Alzheimer's disease may share common behavioral protective factors such as adherence to type 2 diabetes treatment guidelines given that these two diseases have both epidemiological and metabolic similarities. Method: The method used in this study is a retrospective cohort study of 3,797 U.S. Medicare fee-for-service beneficiaries aged 66+ newly diagnosed with type 2 diabetes and without a prior record of Alzheimer's disease based on the Health and Retirement Study. Results: Results of a left-truncated Cox model showed that adherence reduces the risk of Alzheimer's disease by 20% to 24%. Other significant effects were college education (hazard ratio [HR]: 0.65; p value: .023), stroke (HR: 1.40; p value: .013), and 4+ limitations in physical functioning (HR: 1.33; p value: .008). Discussion: Risk of Alzheimer's disease can be reduced by behavioral factors. Possible mechanisms may include earlier start of interventions to reduce blood glucose levels and improve insulin sensitivity.

Abstract
INTRODUCTION Sentinel lymph node biopsy (SLNB) and lymphadenectomy (LAD) are commonly performed in the staging and care of patients with malignant melanoma. These procedures are accompanied by complications that may result in hospital readmission, negatively affecting patient outcomes and potentially affecting surgical procedure reimbursement. The National Surgical Quality Improvement Program (NSQIP) database offers a large data set allowing physicians to evaluate 30-day readmission for surgical complications. We used this database to explore predictors of 30-day hospital readmission for SLNB and LAD in the axillary, cervical, and inguinal regions. METHODS Data from the years 2005 to 2014 of the American College of Surgeons NSQIP database were used. Cohorts were constructed according to International Classification of Diseases, Ninth Revision, classification and current procedural terminology codes. The outcome of 30-day return to hospital was defined as patients who were readmitted to the hospital or the operating room within 30 days. Multiple logistic regression results are presented for a prespecified set of predictors and predictors that were significant on univariate logistic regression analysis. Odds ratios and confidence intervals were calculated using maximum likelihood estimates, along with Wald test P values. RESULTS A total of 3006 patients were included. Of those, 151 (5.0%) returned to the hospital. Among 1235 LAD patients, 65 (5.3%) returned; among 1771 SLNB patients, 86 (4.9%) returned. Smoking was a predictor of hospital readmission for overall SLNB and for cervical SLNB on multivariate analysis. Age was a significant predictor for cervical and inguinal LAD. Hypertension was significant for cervical LAD. Diabetes, preoperative hematocrit, and male sex were predictors for inguinal SLNB. There were no significant predictors for axillary SLNB and axillary LAD, as well as overall LAD procedures. CONCLUSIONS This is the first and largest study using American College of Surgeons NSQIP to examine 30-day readmission after SLNB and LAD for melanoma in 3 commonly operated anatomical regions. We have found several significant risk factors associated with hospital readmission, which are now being used as a quality measure for hospital performance and reimbursement, that may help surgeons optimize patient selection for SLNB and LAD.

Abstract
OBJECTIVES Obesity has been found to be associated with an elevated risk of thyroid nodule(s), mainly in adults; however, evidence for this association in children was limited. The objective of this study was to investigate the association of adiposity and thyroid nodule(s) in children living in iodine-sufficiency areas. SETTING AND PARTICIPANTS We conducted a cross-sectional study of 1403 Chinese children living in the East Coast of China in 2014. OUTCOME MEASURES Anthropometric measures including height, weight and waist and hip circumferences were taken, and body mass index (BMI), body surface area (BSA) and waist-hip ratio (WHR) were then calculated. Thyroid ultrasonography was performed to assess thyroid volume and nodules. RESULTS Based on BMI, 255 (18.17%) children were overweight and 174 (12.40%) were obese. Thyroid nodule(s) was detected in 18.46% of all participants and showed little age and sex variations. As compared with normal-weight children, obese children experienced significantly higher risks for solitary (OR 2.07 (95% CI 1.16 to 3.71)) and multiple (OR 1.67 (95% CI 1.03 to 2.70)) thyroid nodules. Similar associations with thyroid nodule(s) were observed with adiposity measured by waist circumference and BSA, but not WHR. There were no notable differences in the associations between children consuming iodised and non-iodised salt. CONCLUSIONS These findings provide further evidence that childhood obesity is associated with the risk for thyroid nodule(s).

Abstract
IMPORTANCE Changes over time in the incidence of parkinsonism and Parkinson disease (PD) remain uncertain. OBJECTIVE To investigate secular trends (period effects) and birth cohort trends in the incidence of parkinsonism and PD over 30 years in a geographically defined American population. DESIGN, SETTING, AND PARTICIPANTS We used the medical records-linkage system of the Rochester Epidemiology Project to identify incidence cases of PD and other types of parkinsonism in Olmsted County, Minnesota, from 1976 to 2005. All cases were classified by a movement disorder specialist using defined criteria through the review of the complete medical records within the system. The analyses for this study were conducted between May 2015 and January 2016. MAIN OUTCOMES AND MEASURES Incidence rates of parkinsonism and PD over 30 years. We tested for secular trends (period effects) using negative binomial regression models and for birth cohort effects using age-period-cohort models. RESULTS Of 906 patients with parkinsonism, 501 were men, and the median age at onset was 74 years (interquartile range, 66-81 years). Of the 464 patients with PD, 275 were men, and the median age at onset was 73 years (interquartile range, 64-80 years). The overall incidence rates increased significantly over 30 years in men for both parkinsonism (relative risk [RR], 1.17 per decade; 95% CI, 1.03-1.33) and PD (RR, 1.24 per decade; 95% CI, 1.08-1.43). These trends were driven primarily by the older age groups. In particular, for men 70 years or older, incidence rates increased for both parkinsonism (RR, 1.24 per decade; 95% CI, 1.07-1.44) and PD (RR, 1.35 per decade; 95% CI, 1.10-1.65). The secular trends were not significant for women overall or in age strata. We observed an increased risk for both men and women born in the 1920 cohort (1915-1924). However, this birth cohort effect was significant only for PD and only in men. CONCLUSIONS AND REVELANCE Our study suggests that the incidence of parkinsonism and PD may have increased between 1976 and 2005, particularly in men 70 years and older. These trends may be associated with the dramatic changes in smoking behavior that took place in the second half of the 20th century or with other lifestyle or environmental changes. However, the trends could be spurious and need to be confirmed in other populations.

Abstract
Background In the “fourth stage” of epidemiological transition, the distribution of non-communicable diseases is expected to shift to more advanced ages, but age-specific changes beyond 80 years of age have not been reported. Methods This study aimed to evaluate demographic and health transitions in a population aged 80 years and over in the United Kingdom from 1990 to 2014, using primary care electronic health records. Epidemiological analysis of chronic morbidities and age-related impairments included a cohort of 299,495 participants, with stratified sampling by five-year age group up to 100 years and over. Cause-specific proportional hazards models were used to estimate hazard ratios for incidence rates over time. Results Between 1990 and 2014, nonagenarians and centenarians increased as a proportion of the over-80 population, as did the male-to-female ratio among individuals aged 80 to 95 years. A lower risk of coronary heart disease (HR 0.54, 95% confidence interval [CI]: 0.50–0.58), stroke (0.83, 0.76–0.90) and chronic obstructive pulmonary disease (0.59, 0.54–0.64) was observed among 80–84 year-olds in 2010–2014 compared to 1995–1999. By contrast, the risk of type II diabetes (2.18, 1.96–2.42), cancer (1.52, 1.43–1.61), dementia (2.94, 2.70–3.21), cognitive impairment (5.57, 5.01–6.20), and musculoskeletal pain (1.26, 1.21–1.32) was greater in 2010–2014 compared to 1995–1999. Conclusions Redistribution of the over-80 population to older ages, and declining age-specific incidence of cardiovascular and respiratory diseases in over-80s, are consistent with the “fourth stage” of epidemiologic transition, but increases in diabetes, cancer, and age-related impairment show new emerging epidemiological patterns in the senior elderly.

Abstract
Malignant melanoma, a very common type of cancer, is a rapidly growing cancer of the skin with an increase in incidence among the Caucasian population. The disease is seen through all age groups and is very common in the younger age groups. Several studies have examined the risk factors and pathophysiological mechanisms of malignant melanoma, which have enlightened our understanding of the development of the disease, but we have still to fully understand the complex immunological interactions. The examination of the interaction between the human leucocyte antigen (HLA) system and prognostic outcome has shown interesting results, and a correlation between the down- or upregulation of these antigens and prognosis has been seen through many different types of cancer. In malignant melanoma, HLA class Ia has been seen to influence the effects of pharmaceutical drug treatment as well as the overall prognosis, and the HLA class Ib and regulatory T cells have been correlated with tumor progression. Although there is still no standardized immunological treatment worldwide, the interaction between the human leucocyte antigen (HLA) system and tumor progression seems to be a promising focus in the way of optimizing the treatment of malignant melanoma.

Abstract
Human ageing is a fundamental biological process that leads to functional decay, increased risk for various diseases and, ultimately, death. Some of the basic biological mechanisms underlying human ageing are shared with other organisms; thus, animal models have been invaluable in providing key mechanistic and molecular insights into the common bases of biological ageing. In this Review, we briefly summarise the major applications of the most commonly used model organisms adopted in ageing research and highlight their relevance in understanding human ageing. We compare the strengths and limitations of different model organisms and discuss in detail an emerging ageing model, the short-lived African turquoise killifish. We review the recent progress made in using the turquoise killifish to study the biology of ageing and discuss potential future applications of this promising animal model.

Abstract
We investigated trends in the incidence of parkinsonism and Parkinson disease (PD) by comparing data from the first 2 subcohorts of the Rotterdam Study, a prospective, population-based cohort study (first subcohort: baseline 1990 with 10 years of follow-up; second subcohort, baseline 2000 with 10 years of follow-up). From the baseline years, we observed differences in the second subcohort that were associated with a lower risk of PD for some but not all baseline risk factors. Participants in both subcohorts were followed for a maximum of 10 years and monitored for the onset of parkinsonism, the onset of dementia, or death, until January 1, 2011. We used Poisson regression models to compare the incidences of parkinsonism, both overall and by cause (PD and secondary causes), and competitive events (incident dementia and death) as well as the mortality of parkinsonism patients in the 2 subcohorts. In the 1990 subcohort, there were 182 cases of parkinsonism (84 of which were PD) during 57,052 person-years. In the 2000 subcohort, we observed 28 cases of parkinsonism (10 with PD) during 22,307 person-years. The overall age- and sex-adjusted incidence of parkinsonism was lower in the 2000 subcohort (incidence rate ratio = 0.55, 95% confidence interval: 0.36, 0.81), and PD incidence declined sharply (incidence rate ratio = 0.39, 95% confidence interval: 0.19, 0.72). Competitive event rates were lower in the 2000 subcohort, and mortality rates among persons with parkinsonism remained stable. These findings suggest that the incidence of parkinsonism in general, and of PD in particular, decreased between 1990 and 2011.

Abstract
While chronic kidney disease seems to be an independent risk factor for cognitive decline, its impact on cerebral amyloid-β (Aβ) depositions, one hallmark of Alzheimer's Disease (AD) pathology, has not been investigated. Utilizing 80 male nontransgenic spontaneously hypertensive stroke prone rats (SHRSP) at various ages (12 to 44 weeks), tubulointerstitial renal damage, prevalence of cerebral microhemorrhages and Aβ accumulations were quantified. Using age-adjusted general linear models we investigated the main and interaction effects of renal damage and cerebral microhemorrhages on cerebral Aβ load. In addition, using post mortem human brain tissue of 16 stroke patients we examined the co-localization of perivascular Aβ deposits and small vessel wall damage. Statistical models revealed an age-independent main effect of tubulointerstitial kidney damage on brain Aβ accumulations, which was reinforced by the consecutive presence of cerebral microhemorrhages. Moreover, cerebral microhemorrhages independently predicted brain Aβ burden in SHRSP. In up to 69% of all human cases perivascular Aβ deposits were detected in the direct vicinity of small vessel wall damage. Our results support the associations between vascular pathology and Aβ deposition, and demonstrate a relationship between chronic kidney disease and cerebral Aβ pathology. Hence, our data suggest that prevention of chronic renal damage may reduce cerebral Aβ pathology.

A two decade dementia incidence comparison from the Cognitive Function and Ageing Studies I and II. Nat Commun 2016; 7:11398. [PMID: 27092707 PMCID: PMC4838896 DOI: 10.1038/ncomms11398] [Citation(s) in RCA: 267] [Impact Index Per Article: 33.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Accepted: 03/21/2016] [Indexed: 01/29/2023] Open
Abstract
Dramatic global increases in future numbers of people with dementia have been predicted. No multicentre population-based study powered to detect changes over time has reported dementia incidence. MRC Cognitive Function and Ageing Study (CFAS) undertook baseline interviews in populations aged 65+ years in England and Wales (1989–1994). Three areas (CFAS I) were selected for new sampling two decades later (2008–2011) with same geographical boundaries, sampling and approach methods (CFAS II). At 2 years CFAS I interviewed 5,156 (76% response) with 5,288 interviewed in CFAS II (74% response). Here we report a 20% drop in incidence (95% CI: 0–40%), driven by a reduction in men across all ages above 65. In the UK we estimate 209,600 new dementia cases per year. This study was uniquely designed to test for differences across geography and time. A reduction of age-specific incidence means that the numbers of people estimated to develop dementia in any year has remained relatively stable. Future dramatic rises in dementia are widely reported, assuming no change in incidence. Matthews and colleagues report that, in contrast to such statements, age-specific incidence has dropped over 20 years, with overall incidence of dementia remaining stable in a large multi-site population study from England.

Abstract
There has been a significant increase in the number of frail older patients diagnosed with advanced chronic kidney disease (CKD) over the past thirty years. These elderly patients have high levels of comorbidity, and as a consequence the face of renal medicine is changing—There is an increasing need to focus on traditionally geriatric areas of expertise such as falls prevention and rehabilitation, and to shift our emphasis onto improving patient well-being rather than longevity. Over the past decade, many nephrologists have found that they are already acting as de facto “amateur geriatricians”. This denies patients both the benefits of specialist geriatric assessment, and equally importantly denies them access to the wider geriatric multidisciplinary team. This article describes the prevalence and underlying causes of the so-called “Geriatric Giants” in patients with advanced CKD, and discusses possible improvements in care that closer working with geriatricians could bring.

Abstract
Thyroid nodule (TN) and goiter are two common disorders of the thyroid. Despite their benign nature, both conditions can be associated with multiple pathologic conditions including thyroid cancer. In this study, we conducted a large-scale epidemiological study in Chinese women to identify the risk factors implicated in the occurrence of TN and goiter. We analyzed demographic data, lifestyle, medical history, body height, weight, waist circumference, body mass index (BMI), blood pressure, serum glucose and lipids. In addition, thyroid ultrasonography was performed for all subjects. Our results showed that age, menopause, waist circumference, BMI, hypertension, dyslipidemia, and hyperglycemia were associated with both TN and goiter. Furthermore, we found that the prevalence of TN was significantly affected by the medical management of hypertension. Our study suggests that postmenopausal Chinese women with advanced age, obesity, diabetes, and hypertension have an increased awareness of thyroid examination in the annual physical check. Conversely, patients with TN and goiter of the same population may have a higher incidence of age- and obesity-related metabolic disorders.

Abstract
Thyroid nodule (TN) and goiter are two common disorders of the thyroid. Despite their benign nature, both conditions are associated with multiple pathologic conditions including thyroiditis, endocrine dysregulation, and autoimmune disease. In this study we conducted a large-scale epidemiological study in Chinese women to identify risk factors implicated in the pathogenesis of TN and goiter. We analyzed demographic data, medical history, menstrual status, smoking, alcohol consumption, body height, weight, waist circumference, and body mass index (BMI). Thyroid ultrasonography was performed for all subjects. Our results showed that age, menstrual status, BMI, waist circumference, hypertension, dyslipidemia and hyperglycemia had a significant relationship with the prevalence of TN and goiter. There was also a significant association between parity, educational level, smoking, seafood consumption, salt consumption and TN. Waist-hip ratio, BMI, and triglyceride had a significant association with both TN and goiter, and total cholesterol only correlated with TN. Medical management of hypertension significantly affected TN prevalence. Our study also demonstrated age to be a strong predictor of TN and goiter, and obesity a predictor of the likelihood of developing goiter. Thus, our study suggests that the female Chinese population with advance age, menopause, obesity and metabolic syndrome be examined for TN and goiter, and those patients with confirmed TN and goiter be screened for age and obesity related disorders such as metabolic syndrome.
