The International Federation of Gynecology and Obstetrics (FIGO) staging system for Müllerian cancer was changed in 2014. Our objective was to evaluate the prognostic impact of stage IV subclassification in this new staging system, especially focusing on extra-abdominal lymph node metastasis.

Eighty-two patients with stage IV Müllerian cancer treated between 2005 and 2016 at our hospital were retrospectively analyzed. Data for the following clinicopathological variables were analyzed (1) FIGO stage; (2) tumor stage; (3) lymph node status; (4) histologic type; (5) neoadjuvant chemotherapy; (6) optimal surgery; and (7) bevacizumab use. Survival analysis was performed using Kaplan-Meier curves, log-rank tests, and Cox proportional hazards models.

In accordance with the new classification, 28 and 54 patients were classified as FIGO IVA and IVB, respectively. In the Cox proportional hazards model, early-stage tumors (T1b-3b) and optimal surgery were statistically significant favorable prognostic factors.

The research aimed to investigate the average age of recovery in infants with delayed visual maturation (DVM). DVM is diagnosed retrospectively and there are currently no management guidelines. This study gives an evidence-based recovery time which can help clinicians to appropriately reassure anxious parents about DVM prognosis. This research is significant as this is the largest participant study about DVM to date.

This is a retrospective service evaluation of 50 infants with DVM presenting to St James University Hospital between 2012 and 2017. The DVM was classified into either type I or type II. Several key variables were recorded including patient gender, age at recovery, type of DVM and whether Electrodiagnostic testing was used.

STATA analysis showed that the average age of recovery for type I and type II DVM was 6.708 and 13.464months, respectively. A multivariable linear regression adjusted for gender as a confounder. The average age of recovery was 6.179months longer for infants with type II DVM which is a statistically significant difference (95% CI 3.214-9.143, P value < 0.001).

This research supports the hypothesis that the age of recovery in type I DVM is significantly shorter than type II when adjusted for gender. The main limitation is that recovery age is recorded from when the infants attended clinic, however; their vision could have recovered prior to this. In the future, additional multi-centre research needs to be conducted looking at larger patient samples to allow for further sub-categorisation of DVM types.

Increasing background invertebrate herbivory could impede Arctic greening, by serving as a top-down control on tundra vegetation. Many tundra ecosystems are also susceptible to severe insect herbivory outbreaks which can have lasting effects on vegetation communities. To explore how tundra-insect herbivore systems respond to warming, we measured shrub traits and foliar herbivory damage at 16 sites along a landscape gradient in western Greenland. Here we show that shrub foliar insect herbivory damage on two dominant deciduous shrubs, Salix glauca and Betula nana, was positively correlated with increasing temperatures throughout the first half of the 2017 growing season. We found that the majority of insect herbivory damage occurred in July, which was outside the period of rapid leaf expansion that occurred throughout most of June. Defoliators caused the most foliar damage in both shrub species. Additionally, insect herbivores removed a larger proportion of B. nana leaf biomass in warmer sites, which is due to a combination of increased foliar herbivory with a coinciding decline in foliar biomass. These results suggest that the effects of rising temperatures on both insect herbivores and host species are important to consider when predicting the trajectory of Arctic tundra shrub expansion.Trivers and Willard proposed that female mammals should adjust their investment in male versus female offspring relative to their ability to produce high-quality offspring. We tested whether litter size-sex ratio trade-offs predicted by Adaptive Sex Allocation (ASA) theory occur among Richardson's ground squirrel (Urocitellus richardsonii) dams over 10 distinct breeding years in a population where individuals experienced variability in food availability and habitat disruption. Litters of primiparous dams became increasingly female-biased with increasing litter size, but that trend waned among second litters born to dams, and reversed among third litters, with larger litters becoming more male-biased, suggesting that ASA is a product of interacting selection pressures. Trade-offs were not associated with habitat disruption, the availability of supplementary food, or dam age. An association between habitat disruption and male-biased sex ratios, the prevalence of litter size-sex ratio trade-offs and placental scar counts exceeding the number of juveniles at weaning in our population, but not in a geographically distinct population of conspecifics exposed to different environmental conditions reveal that the expression of ASA varies among populations and among years within populations, illustrating the conditional nature of ASA.Non-native plants may benefit, briefly or permanently, from natural enemy release in their invaded range, or may form novel interactions with native enemy species. Likewise, newly arrived herbivores may develop novel associations with native plants or, where their hosts have arrived ahead of them, re-establish interactions that existed previously in their ancestral ranges. KPT-185 Predicting outcomes from this diversity of novel and re-established interactions between plants and their herbivores presents a major challenge for invasion biology. We report on interactions between the recently arrived invasive planthopper Prokelisia marginata, and the multi-ploidy Spartina complex of four native and introduced species in Britain, each representing a different level of shared evolutionary history with the herbivore. As predicted, S. alterniflora, the ancestral host, was least impacted by planthopper herbivory, with the previously unexposed native S. maritima, a nationally threatened species, suffering the greatest impacts on leaf length gain, new leaf growth and relative water content.
