Abstract

OBJECTIVE: This study aimed to evaluate the effects of affected knee flexion for 24 vs. 72 hours on blood loss, pain, range of motion, and functional outcomes after total knee arthroplasty. PATIENTS AND METHODS: The present study included 46 participants with a mean age of 64.33 ± 6.70 years. The affected knee of the first 23 participants, based on the order of operations, was positioned at 70° flexion for 24 hours, and the knee of the next 23 participants was positioned at 70° flexion for 72 hours. Participants were evaluated before the operation and on postoperative day 3 and week 6. Pain, edema, range of motion, time up and go test scores, and Western Ontario McMaster Universities Arthritis Index scores, hemoglobin, and hematocrit were measured before the operation and on postoperative at day 3 and week 6. RESULTS: We found that the calculated blood loss was 575.07 ± 282.44 and 578.39 ± 297.11 mL in patients who underwent short- and long-duration flexion positioning, respectively (p = 0.921). The active flexion angles at postoperative week 6 were 83.61° ± 22.03° and 105.91° ± 13.06° in the short- and long-duration flexion groups, respectively (p < 0.01). Furthermore, the Western Ontario and McMaster Universities Arthritis Index scores at postoperative week 6 were 35.52 ± 24.71 and 17.17 ± 15.37 in the short- and long-duration flexion groups, respectively (p < 0.01). CONCLUSIONS: Long-duration flexion positioning after total knee arthroplasty may lead to better middle-term flexion range of motion and physical function scores than short-duration flexion positioning.

Abstract

The present study aimed to evaluate the effect of dietary organic or inorganic selenium (Se) supplementation on laying and hatching performance, egg Se content and liver glutathione peroxidase (GSH-Px) concentration of egg-type breeders as well as their offspring antioxidant status under 36 h post-hatch feed withdrawal. Two hundred and seventy white egg-type breeders were used. The hens were randomly assigned to five dietary treatments. The basal diet contained no supplemental Se (Control). The four treatment groups consisted of two selenium sources (inorganic and organic, Seinorg and Seorg, respectively) and two selenium levels (0.20 and 0.35 mg Se/kg diet). The total analysed Se concentration in the diets was between 0.137 and 0.138 mg/kg for Control, while it was 0.342 and 0.340 mg/kg for 0.20 Seinorg, 0.339 and 0.351 mg/kg for 0.20 Seorg, 0.485 and 0.489 mg/kg for 0.35 Seinorg, 0.481 and 0.495 mg/kg for 0.35 Seorg from 21 to 40 and 41 to 49 weeks, respectively. There was no effect of diets on laying performance, egg quality, and hatchability. Dietary Se supplementation increased egg Se content compared to Control, being higher in eggs from hens fed Seorg than those from hens fed Seinorg. Liver GSH-Px activity of hens fed 0.35 mg Se/kg was higher than in hens fed 0.20 mg/kg Se. On d of hatch and 36 h post-hatch, residual yolk sac Se content of chicks from hens fed 0.35 mg Se/kg was higher than that of chicks from hens fed 0.20 mg/kg Se. After 36 h post-hatch feed withdrawal, plasma and liver GSH-Px activity of chicks from Se groups were higher than in chicks from the Control. It was concluded that dietary maternal Se would provide a protective mechanism for day-old chicks for coping with stressful situations exposed after hatching. © Verlag Eugen Ulmer, Stuttgart., Ministry of Agriculture - Saskatchewan: D/16/A06/P02/02 Ministry of Agriculture of the People's Republic of China, MOA: TAGEM/HAYSÜD/16/A06/P02/02, This study was supported by the Ministry of Agriculture, Project Number: TAGEM/HAYS?D/16/A06/P02/02., This study was supported by the Ministry of Agriculture, Project Number: TAGEM/HAYSÜD/16/A06/P02/02
