This project aimed to identify the impact of driving cessation from the perspectives of older drivers and former drivers. Participants included 17 adults aged 65-88 years residing in a city in Northwestern Ontario, Canada. Using a semi-structured interview guide (with questions regarding mobility, personal impact, impact on others, engagement with life, and finances), two focus groups were held with nine current drivers, and one-on-one interviews were held with six former drivers and two current drivers. Two themes emerged concerning stopping driving...

In temperate urbanized areas where road salting is used for winter road maintenance, the level of chloride in surface waters has been increasing. While a number of studies have shown that the early-life stages of freshwater mussels are particularly sensitive to salt; few studies have examined the toxicity of salt-impacted winter road runoff to the early-life stages of freshwater mussels to confirm that chloride is the driver of toxicity in this mixture. This study examines the acute toxicity of field-collected winter road runoff to the glochidia of wavy-rayed lampmussels (Lampsilis fasciola) (48 h exposure) and newly released juvenile fatmucket mussels (Lampsilis siliquoidea) (<1 week old; 96 h exposure) under different water hardness...

Understanding and managing pollination service is hindered by taxonomic impediments and paucity of data, particularly in the tropics. Herein we apply integrative species delineation and taxonomy to test impacts of land use on the diversity of bee communities within Xishuangbanna (Yunnan, south China), a highly biodiverse tropical region which has undergone extensive land conversion to rubber plantation. 128 Operational Taxonomic Units (OTU) were inferred by an iterative and integrative approach. Bee activity differed significantly across land use samples, although community composition corresponded more to level of vegetation density, when accounting for spatial structure...

PURPOSE OF REVIEW: Inflammatory bowel disease (IBD) is a multifactorial disease caused by dysregulated immune responses to commensal or pathogenic intestinal microbes, resulting in chronic intestinal inflammation. Patients diagnosed with IBD occurring before the age of 5 are a unique population, known as very early onset (VEO)-IBD and can be phenotypically and genetically distinct from older-onset IBD. We aim to review the clinical presentation of children with VEO-IBD and recent discoveries that point to genomic drivers of disease that may impact our therapeutic decisions...

BACKGROUND: Few studies have investigated older patients with regards to general practice follow-up after an emergency department (ED) admission. We measured the proportion of older patients given explicit general practice follow-up instructions who sought care by day seven after an ED admission. METHODS: Patients discharged from Fairfield Hospital ED (south-western Sydney) who were 65 years and older were approached for a structured telephone interview. Data from the interview and patients' ED discharge summaries were analysed descriptively...

BACKGROUND: Little is known about resource use in the care of neuroendocrine tumors (NETs). This study defined patterns of costs in NET management and compared them with those of a more common malignancy, colon cancer (CC). METHODS: Using a provincial cancer registry (2004-2012), NET patients were identified and matched at a ratio of 1-3 with CC patients. Four phases of care were examined: pre-diagnostic (PreDx: -2 years to -181 days), diagnostic (Dx: -180 days to +180 days), postdiagnostic (PostDx: +181 days to +3 years), and prolonged post-diagnostic (PPostDx: +181 days to +9 years)...

Advances are being made in vehicle technologies that may help older adults compensate for some of the declines in abilities associated with aging. These advances hold promise for increasing vehicle safety, reducing injuries, and making the driving task more comfortable. However, important research gaps remain with regard to how various advanced technologies impact the safety of older drivers, as well as older drivers' perceptions about these technologies. This special issue contains seven original contributions that address these issues...

As age increases, immune responses and consequently protection following vaccination to seasonal influenza is commonly believed to decrease. Possible drivers of this immune dysfunction include immunosenescence, repeated exposure to the same seasonal influenza antigens, and prior infection with cytomegalovirus (CMV). Here, to determine immune parameters distinguishing vaccine humoral responders (R) from non-responders (NR) following vaccination, we surveyed broad peripheral blood "cellular immune correlates" of older adults vaccinated with Fluad® (an adjuvanted subunit influenza vaccine containing strains H1N1, H3N2 and B)...

Concordance between mutations in the primary papillary thyroid carcinoma (PTC) and the paired x lymph node metastasis may elucidate the potential role of molecular targeted therapy in advanced stages. BRAF and NRAS mutations in primary PTC (n = 253) with corresponding metastatic lymph node (n = 46) were analyzed utilizing StripAssays (ViennaLab Diagnostics). Statistical analysis was performed using (SPSS, Inc.), version 24.0 with a p-value of <0.05, and concordance via kappa agreement. BRAF mutation frequency in conventional PTC (cPTC): 56...

Erdheim-Chester Disease (ECD) is a rare non-Langerhans Cell histiocytosis that most commonly affects adults and is driven by a high frequency of mutations in BRAF, MAP2K1, and kinases promoting MAP kinase signaling. Due to the relative rarity of ECD, key clinical features of the disease may not be well defined. Across a multi-institutional cohort of 189 patients with ECD and ECD overlapping with Langerhans Cell Histiocytosis (so-called Mixed Histiocytosis (MH)), we identified an unexpected and heretofore undescribed frequent occurrence of myeloid neoplasms amongst patients with ECD and MH...

The relationship between age and breast cancer subtype is complex: both impact risk of locoregional recurrence (LRR) and survival. Young patients frequently present with aggressive tumors but the increased risk imparted by young age appears to differ among breast cancer subtypes. Dramatic improvements in local control among young women with breast cancer of all tumor subtypes have been observed, likely attributable to improved local therapy strategies, improvements in adjuvant therapies and implementation of subtype-specific targeted therapies...

Non-small cell lung cancer (NSCLC) patients tend to develop brain metastases (BM), but the link between BM occurrence and driver mutations in NSCLC is not very clear. We explored whether activating mutations of epidermal growth factor receptors (EGFRs) in exon 19 deletion or L858R predict BM in NSCLC. A retrospective multivariable logistic regression analysis of 384 patients demonstrated that the presence of mutated-EGFRs was associated with overall BM (OR=2.24, P=0.001) compared to that of wild-type EGFR (WT-EGFR)...

OBJECTIVE: Magnitude and independent drivers of the risk of acute arterial events in IBD are still unclear. We addressed this question in patients with IBD compared with the general population at a nationwide level. DESIGN: Using the French National Hospital Discharge Database from 2008 to 2013, all patients aged 15 years or older and diagnosed with IBD were identified and followed up until 31 December 2013. The rates of incident acute arterial events were calculated and the impact of time with active disease (period around hospitalisation for IBD flare or IBD-related surgery) on the risk was assessed by Cox regression adjusted for traditional cardiovascular risk factors...

BACKGROUND: Rates of new HIV infections continue to increase worldwide among men who have sex with men (MSM). Despite effective prevention strategies such as condoms and pre-exposure prophylaxis (PrEP), low usage of both methods in many parts of the world hinder prevention efforts. An individual's perceptions of the risk of acquiring HIV and the seriousness they afford to seroconversion are important drivers of behavioral risk-taking. Understanding the behavioral factors suppressing the uptake of HIV prevention services is a critical step in informing strategies to improve interventions to combat the ongoing HIV pandemic among MSM...

We measured plasma levels of high-sensitivity C-reactive protein (hs-CRP) in 526 subjects with primary myelofibrosis (PMF). Thirty-eight percent had an elevated hs-CRP level (≥0.3mg/dL). Elevated hs-CRP levels were associated with a progressive disease phenotype, including anemia, high white blood cell count, low platelet count, increased splenomegaly, increased risk of blast transformation, and worse survival. Age≥52years, but no other demographic characteristics, was associated with an elevated hs-CRP level in multivariable logistic regression (odds ratio [OR], 4...

The purpose of this pilot study was to explore the relationships between sleep, work practices, speed of processing, and 5-year motor vehicle crash risk among a group of older truck drivers. Anthropometric, demographic, and psychological data were recorded, along with health, sleep, and work histories from a sample of 23 truck drivers. Results from this pilot study suggest that physical fatigue may play a role in processing speed. Future studies should be designed with adequate power and include objective measures of sleep and repeated measures over time to determine 5-year MVC rates...

There is strong policy interest, in England as elsewhere, in slowing the growth in emergency hospital admissions, which for older people increased by 3.3% annually between 2001/2 and 2012/3. Resource constrains have increased the importance of understanding rising emergency admissions, which in policy discourse is often explained by population aging. This study examines how far the rise in emergency admissions of people over 65 was due to population ageing, how far to the changing likelihood of entering hospital at each age, and how far to other factors which might be more amenable to policy measures...
