360 PROFILING FRAILTY IN A POPULATION OF OLDER FARMERS IN THE WEST OF IRELAND

Background

Identification of different groups at risk of frailty is a key research focus. Farmers frequently have higher prevalence of some health problems; however, they undertake high levels of physical activity which may provide protection against the development of frailty in this cohort. To date, no published research has examined prevalence of frailty levels in older farmers in Ireland. This research aimed to profile frailty levels of older farmers in the west of Ireland, and, establish if there is an association between frailty levels in this group and different farming specific demographics/socioeconomic factors such as; type of farming undertaken, amount of time spent farming outdoors and amount of land owned by farmers

Methods

This cross-sectional study recruited older farmers via livestock marts in the west of Ireland. A questionnaire regarding participants characteristics and farming demographics was provided to participants. This questionnaire also included the Program on Research for Integrating Services for the Maintenance of Autonomy (PRISMA-7) questionnaire and the short 5-question assessment of Fatigue, Resistance, Aerobic capacity, Illnesses, and Loss of weight (FRAIL) questionnaire to assess frailty. Data were analysed using STATA statistical software.

Results

In total, 58 older farmers participated in the study. Results showed found that two participants (3.5%) were ‘frail’, with 27 participants (47%) classified as ‘prefrail’. An association existed between the type of farming undertaken and frailty levels based on the FRAIL scale (p=0.009). No association was found between frailty levels and the amount of land owned by farmers (p=0.34) or the amount of time spent farming outdoors (p=0.18).

Conclusion

A minority of participants in this study were classified as frail. The type of farming undertaken by farmers may have an association with frailty levels. Results should be interpreted with caution secondary to the small sample size and the small geographical scope of recruitment.

Novel mouse model of indwelling pleural catheter in mice with malignant pleural effusion

Malignant pleural effusion (MPE) is an indicator of advanced stage malignancy. There are an estimated 150 000 to 200 000 cases of MPE diagnosed annually in the USA [1]. During the past 10 years, the types of cancer treatment and pleural procedures available for MPE have expanded leading to improved stratification and better individualisation of treatment [2]. A recently published prognostic score (PROMISE score) improved prediction of the 3 month risk of death in patients with MPE, thereby improving the selection of appropriate management strategies [3].

This novel mouse model mimics malignant pleural effusion drainage using an indwelling pleural catheter in humans, and provides direct access to the pleural space potentially enabling the testing of intrapleural therapies in the treatment of MPE.bit.ly/2W2kzO0

Identifying women at increased risk of breast cancer: Can we use genotyping at low penetrance loci?

162

Background: Most inherited predisposition to breast cancer is attributable to low penetrance susceptibility loci, a number of which have been identified through genome-wide association studies. Although individually each locus has a small effect, combining data from multiple loci would be expected to provide more risk information. We investigated the size of risk determination that can be achieved using genotyping at 18 loci. We then calculated its effect when combined with risk estimated from family history alone in terms of management under UK guidelines, where a woman who has a 10 year risk of 3% or greater requires additional breast screening from a younger age.

Methods: Genotyping for 18 loci was carried out in 253 women at increased risk of breast cancer due to a positive family history and 118 matched controls. The relative risks conferred by genotype at the 18 loci were combined under a log-additive model and transformed into a log-polygenic risk. The BOADICEA risk estimation tool was used to calculate breast cancer risk due to family history.

Results: Both the increased risk and control groups demonstrated a normal distribution of log-polygenic risk with similar variance. There was a significantly higher mean in the increased risk compared to the control group (mean = 0.1313 and 0.0874 respectively, p = 0.007). No significant correlation was found between polygenic risk calculated from genotype data and the family history risk estimated using BOADICEA. When polygenic risk was combined with family history risk there was significant reclassification of risk for those with a family history. 36.76% moved into a higher risk category while 3.68% moved into a lower risk category.

Conclusions: Our data suggests that genotyping will be clinically relevant for estimating breast cancer risk. Individuals with a family history overall have a higher genotype risk than the population. The lack of correlation of genotype risk with BOADICEA risk suggests that the two risk estimates can be considered independently. By combining genotype with family history data, we demonstrated a significant reclassification of risk for individuals with a family history, with better identification of women in this group requiring intervention.

Filling defects of the kidney pelvis

Filling defects in the renal pelvis should alert radiologists to the possibility of underlying tuberculosis. A case is presented with the major criteria used in differentiating tuberculosis from a neoplasm.

The effect of acute hyperglycemia on flow velocity in the macular capillaries

The effect of acute hyperglycemia on retinal blood flow was measured in 12 diabetic patients (mean blood glucose, 276 mg%) on continuous subcutaneous insulin infusion and six nondiabetic controls (mean blood glucose, 198 mg%). Flow velocity measurements in macular capillaries were made using the blue field entoptic method. Retinal artery and vein diameters were measured using red-free fundus photographs. No significant change in flow velocity or retinal vessel diameter was noted in either group.
