BACKGROUND: The relationship between light intensity physical activity (PA), which is common in older adults, and cardiovascular disease (CVD) risk factors is unclear. This study examined associations of accelerometer-measured PA intensity with CVD risk factors in older women of different race-ethnicities. METHODS AND RESULTS: Cross-sectional analyses were conducted in 4832 women (mean age 78.9 years; 52.5% white, 30.5% black, 17.1% Hispanic) who were without known CVD and wore triaxial accelerometers a minimum of 4 of 7 days with ≥10 hours/d awake wear-time...

Inhalation of particulate matter less than 10 µm in diameter (PM10) has a range of implications for respiratory health. In order to mitigate these effects regulatory bodies have set ambient air quality guidelines based on the known dose-response relationships between PM10 exposure and health outcomes. However, these data are based almost entirely on PM10 from urban regions, which are typically dominated by particulates from combustion sources. In contrast, there are limited data on the respiratory health effects of particles from nonurban regions that often contain a high geogenic (earth derived) component...

Parkinson's disease (PD) is pathologically characterized by the presence of intraneuronal inclusions, termed Lewy bodies and Lewy neurites, whose main component is alpha-synuclein. Based on the topographic distribution of Lewy bodies and neurites established after autopsy from PD patients, Braak and coworkers hypothesized that PD pathology may start in the gastrointestinal tract then spread through the vagus nerve to the brain. This hypothesis has been reinforced by the discovery that alpha-synuclein may be capable of spreading transcellularly, thereby providing a mechanistic basis for Braak's hypothesis...

Young African females are at increased risk of HIV acquisition, and genital inflammation or the vaginal microbiome may contribute to this risk. We studied these factors in 168 HIV negative South African adolescent women aged 16-22 years. Unsupervised clustering of 16S rRNA gene sequences revealed three clusters (subtypes), one of which was strongly associated with genital inflammation. In a multivariate model, microbiome compositional subtype and hormonal contraception were significantly associated with genital inflammation...

Distinguishing dementia subtypes can be difficult due to similarities in clinical presentation. There is increasing interest in discrete gait characteristics as markers to aid diagnostic algorithms in dementia. This structured review explores the differences in quantitative gait characteristics between dementia and healthy controls, and between four dementia subtypes under single-task conditions: Alzheimer's disease (AD), dementia with Lewy bodies and Parkinson's disease dementia, and vascular dementia. Twenty-six papers out of an initial 5,211 were reviewed and interpreted using a validated model of gait...

Due to environmental insult or innate genetic deficiency, protein folding environments of the mitochondrial matrix are prone to dysregulation, prompting the activation of a specific organellar stress-response mechanism the mitochondrial unfolded protein response (UPR(MT)). In Caenorhabditis elegans, mitochondrial damage leads to nuclear translocation of the ATFS-1 transcription factor to activate the UPR(MT) After short-term acute stress has been mitigated, the UPR(MT) is eventually suppressed to restore homeostasis to C...

BACKGROUND: The diagnosis of dementia with Lewy bodies (DLB) is based on diagnostic clinical criteria, which were updated over the years. OBJECTIVE: To evaluate, through a systematic review, accuracy of the diagnostic criteria, testing a possible improvement over time. METHODS: We searched on MEDLINE and SCOPUS databases for studies reporting diagnostic parameters regarding the clinical diagnosis of DLB until October 2016. We performed meta-analysis, using a Bayesian approach, on those using pathological examination as gold standard, subclassified based on the different diagnostic criteria used...

Captive bears are housed in environments that differ greatly from their natural habitat, restricting their ability to perform normal species-specific behaviours. This may be detrimental to welfare, with disabled individuals at particular risk. The effect of physical disability on behaviour and enclosure utilisation was assessed in 12 adult Malayan sun bears (Helarctos malayanus) using 10minute interval scan sampling. Amputees spent less time performing locomotor behaviours than able-bodied bears, used their enclosures less evenly, but did not exhibit obvious stereotypies...

This review provides an update about cardiac sympathetic denervation in Lewy body diseases. The family of Lewy body diseases includes Parkinson's disease (PD), pure autonomic failure (PAF), and dementia with Lewy bodies (DLB). All three feature intra-neuronal cytoplasmic deposits of the protein, alpha-synuclein. Multiple system atrophy (MSA), the parkinsonian form of which can be difficult to distinguish from PD with orthostatic hypotension, involves glial cytoplasmic inclusions that contain alpha-synuclein...

Parkinson's disease (PD) pathology is characterized by the abnormal accumulation and aggregation of the pre-synaptic protein α-synuclein in the dopaminergic neurons as Lewy bodies (LBs). Curcumin, which plays a neuroprotective role in various animal models of PD, was found to directly modulate the aggregation of α-synuclein in in vitro as well as in in vivo studies. While curcumin has been shown to exhibit strong anti-oxidant and anti-inflammatory properties, there are a number of other possible mechanisms by which curcumin may alter α-synuclein aggregation which still remains obscure...

A nil-by-mouth regime with enteral nutrition via an artificial route is frequently applied following esophagectomy. However, early initiation of oral feeding could potentially improve recovery and has shown to be beneficial in many types of abdominal surgery. Although short-term nutritional safety of oral intake after an esophagectomy has been documented, long-term effects of this feeding regimen are unknown. In this cohort study data from patients undergoing minimal invasive Ivor-Lewis esophagectomy between 04-2012 and 09-2015 in three centers in The Netherlands were collected...

Synucleinopathies are a family of neurodegenerative disorders that comprises Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. Each of these disorders is characterized by devastating motor, cognitive, and autonomic consequences. Current treatments for synucleinopathies are not curative and are limited to improvement of quality of life for affected individuals. Although the underlying causes of these diseases are unknown, a shared pathological hallmark is the presence of proteinaceous inclusions containing the α-synuclein (α-syn) protein in brain tissue...

Few studies have investigated the role of inflammation in Lewy body dementia (LBD) and variable results have been found. We systematically reviewed the literature for evidence of systemic inflammatory changes in dementia with Lewy bodies and Parkinson disease dementia. Owing to the low number of studies we also included Parkinson disease. Key terms were used to search the relevant databases. Titles and abstracts were screened and potentially relevant articles were reviewed in full. References of included studies and relevant reviews were searched...
