Abstract:
An experimental study has been conducted to determine the stress–strain behaviour of human corneal tissue and how the behaviour varies with age. Fifty-seven well-preserved ex vivo donor corneas aged between 30 and 99 years were subjected to cycles of posterior pressure up to 60 mm Hg while monitoring their behaviour. The corneas were mechanically clamped along their ring of scleral tissue and kept in physiological conditions of temperature and hydration. The tissue demonstrated hyper-elastic pressure-deformation and stress–strain behaviour that closely matched an exponential trend. Clear stiffening (increased resistance to deformation) with age was observed in all loading cycles, and the rate of stiffness growth was nonlinear with bias towards older specimens. With a strong statistical association between stiffness and age ( p < 0.05), it was possible to develop generic stress–strain equations that were suitable for all ages between 30 and 99 years. These equations, which closely matched the experimental results, depicted corneal stiffening with age in a form suitable for implementation in numerical simulations of ocular biomechanical behaviour.

Abstract:
178 Background: Despite advances in therapy, metastatic prostate cancer (mPCA) remains lethal. Younger men with mPCA have a significantly greater risk of mPCA-related death compared to men diagnosed later in life. This suggests that early-onset mPCA is a uniquely aggressive subtype of disease, however, the genomic drivers have not been explored. Here, we analyze data from 2,196 mPCA specimens profiled as part of routine clinical care. Methods: Comprehensive genomic profiling was performed by hybridization capture of exonic regions from either 236, 315 or 324 cancer-related genes and select introns from 19 genes commonly rearranged in cancer. Libraries were sequenced to high, uniform coverage and assessed for all classes of genomic alterations. Tumor mutational burden (TMB) was determined from 1.1 Mb of sequence and microsatellite instability (MSI) from 114 loci. Results: 336 (15.3%) men were < 60 years old (yo), and 1,860 (84.7%) were ≥60 yo at time of biopsy. Lymph node, liver, and bone were the three most common metastatic sites in both groups, accounting for 75% of all specimens. Patients < 60 yo harbored significantly fewer AR and PTEN point mutations when compared to patients ≥60 yo (OR = 0.48, p < 0.001; OR = 0.51, p = 0.01). Copy number alterations in PTEN and CDKN2A/B were significantly more common among young patients (OR = 1.46, p = 0.003; OR = 1.91, p = 0.04). AR copy number alterations were significantly less common among young patients (OR = 0.57, p < 0.001). Although uncommon in mPCA, markers of genomic instability including MSH2 mutations and MSI were both significantly less common among patients < 60 yo (0.00% vs. 1.29%, p = 0.04; 0.89% vs. 3.06%, p = 0.03). There were no significant differences in the frequency of TP53, APC, BRCA2, ATM, and CDK12 point mutations, MYC copy number alterations, or TMPRSS2-ERG fusions. The average TMB was not significantly different between young and old patients, with 3.26 and 5.79 mutations per Mb, respectively (p = 0.19). Conclusions: Younger men with mPCA appear to represent a genomically distinct disease subtype. To better define this population, we are prospectively investigating the genomic, genetic, and environmental risk factors through an ongoing PCF funded clinical trial.

Abstract:
Males of thePiezodorus hybneristink bug produce a pheromone comprisingβ-sesquiphellandrene (Sesq), (R)-15-hexadecanolide (R15), and methyl (Z)-8-hexadecenoate (Z8). We collected airborne volatiles from individualP. hybnerimales and analyzed them by GC-MS. Daily analysis from 1 to 16 days after adult emergence showed that pheromone emission started around 3 to 6 days after adult emergence and peaked (~1 μg/male/day) on day 11. The proportion of Sesq tended to increase with age to about 80% on days 12 to 16. On the other hand, the proportion of R15 tended to decrease with age. The proportion of Z8 reached a maximum of about 34% on day 9 but otherwise remained below 20%. The total amount of pheromone emitted by individual males varied considerably: three males emitted more than 10 μg, whereas another three males emitted little or no pheromone and failed to survive by the end of the experiment. These results suggest that the amount ofP. hybneripheromone and its blend ratio could be affected by the male’s physical conditions, such as vitality and age.

Abstract:
In this study, a comprehensive evaluation of static and dynamic balance abilities was performed in young and older adults and regression analysis was used to test whether age-related variations in individual ankle muscle mechanical properties could explain differences in balance performance. The mechanical properties included estimates of the maximal isometric force capability, force-length, force-velocity, and series elastic properties of the dorsiflexors and individual plantarflexor muscles (gastrocnemius and soleus). As expected, the older adults performed more poorly on most balance tasks. Muscular maximal isometric force, optimal fiber length, tendon slack length, and velocity-dependent force capabilities accounted for up to 60% of the age-related variation in performance on the static and dynamic balance tests. In general, the plantarflexors had a stronger predictive role than the dorsiflexors. Plantarflexor stiffness was strongly related to general balance performance, particularly in quiet stance; but this effect did not depend on age. Together, these results suggest that age-related differences in balance performance are explained in part by alterations in muscular mechanical properties.

Abstract:
BackgroundStudies have reported seasonal variations regarding the incidence and the short-term mortality of pulmonary embolism (PE). The aim of this study was to identify sex-specific and age-related differences in seasonal patterns regarding hospitalisations and mortality of PE patients.MethodsWe analysed the impact of seasons on incidence and in-hospital mortality of male and female hospitalised PE patients in Germany (2005–2015) based on the German nationwide inpatient sample.ResultsThe German nationwide inpatient sample comprised 885 806 hospitalisations due to PE (2005–2015). Seasonal variations of both incidence (p=0.021) and in-hospital mortality (p<0.001) were of significant magnitude. Quarterly annual incidence (25.5 versus 23.7 of 100 000 citizens per year, p=0.021) and in-hospital mortality (17.0% versus 16.7%, p=0.008) were higher in winter than in summer. Risk of in-hospital mortality in winter was slightly higher (OR 1.03 (95% CI 1.01–1.06), p=0.015) compared to summer, independently of sex, age and comorbidities. Additionally, we observed sex-specific differences during seasons: the highest number of hospitalisations of PE patients of both sexes was during winter, whereas the nadir of male patients was in spring and that of female patients was in summer. Both sexes showed a maximum of in-hospital mortality in spring. Seasonal variation regarding incidence and mortality was pronounced in older patients.ConclusionIncidence and the in-hospital mortality of PE patients showed a significant seasonal variation with sex-specific differences. Although it has to be hypothesised that the seasonal variation of PE is multifactorially dependent, variation in each season was not explained by seasonal differences regarding age, sex and the prevalence of important comorbidities.
