Nutritional assessment of an Italian population of elderly hip fracture patients: a comparison between sexes and types of fractures.

Malnutrition is highly prevalent in elderly patients with hip fractures (HF) (intracapsular and extracapsular). Many factors influence the patterns of HF, but the role of nutrition is not yet clear. In this investigation, an analysis of the body compositions of geriatric patients with HF was conducted, to identify differences in the nutritional status between male and female patients with intra- and extra-capsular HF. The nutritional assessment of patients was performed using three different techniques: anthropometrics measurement, plicometry, and bioimpedance analysis. The most prevalent type of fracture in females was the extracapsular type, while the intracapsular type is more common in males. Males showed a lower BMI, fat percentage and a greater length of hospital stay (LOS). Patients with intracapsular fractures are more malnourished compared with patients with extracapsular fractures. Males with HF have a higher prevalence of intracapsular fractures compared to women and stayed in hospital longer.

Surgery within 48 hours in hip fractures in elderly patients exerts a positive effect on post-operative hyponatremia.

This study investigated the prevalence of hyponatremia during the hospital stay, in a cohort of elderly patients with hip fractures who underwent surgery within 48 h from admission. Records data were retrieved from the database of the San Giovanni di Dio e Ruggi d'Aragona Hospital of Salerno, Italy. All elderly patients (≥65 years old) with a documented hip fracture that underwent surgery within 48 h from admission, between 2016 and 2018, were included and divided in 4 subgroups according to their sex and type of fracture. Serum sodium concentration were monitored during the hospital stay and collected at admission, before surgery, after surgery and at discharge. The overall prevalence of hyponatremia was 23.99% (n=71/295), (24.3%, n=57/234 for female patients and 22.9%, n=14/61 for male patients). The percentage of hyponatremic patients with an intracapsular hip fracture was 27.17% (n=25/92), and 22.66% (n=46/203) in patients with an extracapsular hip fracture. The highest value of mean serum sodium concentration (139.2 mmol/L±4.4 SD) was found at the hospital discharge phase, and the lowest value (138.4 mmol/L±4.3 SD) was found during the pre-surgery phase. The lowest mean value of serum sodium was found before surgery, while the highest was after surgery. This could suggest that the early operative treatment and the accurate in-hospital monitoring are effective to treat or prevent this condition.
