RESUMO
OBJECTIVE: To assess whether enhanced daily weekend physiotherapy (EWP) for patients with hip fracture was associated with improved clinical outcomes. METHODS: We retrospectively analysed all previously ambulatory adults admitted with hip fracture to our tertiary hospital, comparing 'usual' ('control') care (09/19-03/20) to EWP (09/20-03/21). Outcomes included Day-7 mobility ≥20 m (primary), additional mobility measures, specified postoperative complications, new residential facility placement, acute length-of-stay (LOS) and 30-day death. RESULTS: Amongst 235 eligible patients (128 control, 107 EWP), 66% were female, mean age was 80.4 years (SD 10.5), 20% from residential care and 49% (114/235) were mobilising without aid at baseline (no between-group differences; all p ≥ .20). Median acute LOS was 10 days (IQR 6-15), total hospital LOS was 21 days (IQR 12-37) and 3% (n = 6) died by Day 30. Median Day-7 distance mobilised was 25 m (IQR 7-50) with EWP versus 10 m (3-40) (p = .06). No EWP patients developed pressure injury (0 vs. 6, p = .02); other outcomes were similar between groups. Adjusting for age, residence, baseline cognitive impairment, American Society of Anesthesiologist score and preadmission mobilisation without aids, EWP was independently associated with increased likelihood of mobilising ≥20 m at Day 7 (aOR 1.83, 95% CI 1.04-3.23, p = .03). CONCLUSIONS: Enhanced daily weekend physiotherapy was associated with improvement in early mobility, but not other outcomes assessed. These data would be strengthened by randomised controlled trial data exploring more intense physiotherapy, cost-benefit analysis and patient experience measures.
RESUMO
BACKGROUND: Dairy cows are at high risk of fatty liver disease in early lactation, but current preventative measures are not always effective. Cows with fatty liver have lower circulating branched-chain amino acid (BCAA) concentrations whereas cows with high circulating BCAA levels have low liver triglyceride (TG). Our objective was to determine the impact of BCAA and their corresponding ketoacids (branched-chain ketoacids, BCKA) on production performance and liver TG accumulation in Holstein cows in the first 3 weeks postpartum. METHODS: Thirty-six multiparous Holstein cows were used in a randomized block design experiment. Cows were abomasally infused for the first 21 d postpartum with solutions of 1) saline (CON, n = 12); 2) BCA (67 g valine, 50 g leucine, and 34 g isoleucine, n = 12); and 3) BCK (77 g 2-ketovaline calcium salt, 57 g 2-ketoleucine calcium salt, and 39 g 2-ketoisoleucine calcium salt, n = 12). All cows received the same diet. Treatment effects were determined using PROC GLIMMIX in SAS. RESULTS: No differences were detected for body weight, body condition score, or dry matter intake averaged over the first 21 d postpartum. Cows receiving BCK had significantly lower liver TG concentrations compared to CON (6.60% vs. 4.77%, standard error of the mean (SEM) 0.49) during the first 3 weeks of lactation. Infusion of BCA increased milk yield (39.5 vs. 35.3 kg/d, SEM 1.8), milk fat yield (2.10 vs. 1.69 kg/d, SEM 0.08), and lactose yield (2.11 vs. 1.67 kg/d, SEM 0.07) compared with CON. Compared to CON, cows receiving BCA had lower plasma glucose (55.0 vs. 59.2 mg/dL, SEM 0.86) but higher ß-hydroxybutyrate (9.17 vs. 6.00 mg/dL, SEM 0.80). CONCLUSIONS: Overall, BCAA supplementation in this study improved milk production, whereas BCKA supplementation reduced TG accumulation in the liver of fresh cows.
