BACKGROUND Radiocarpal dislocations are rare but potentially devastating *** outcomes are associated with inadequate or lost reduction,such as ulnar translocation,but no consensus exists on the ideal fixation *** bridge plate fixation has been described for various settings in the treatment of complex distal radius fractures and can be fixed distally to the second or third metacarpal,but its application for radiocarpal dislocations has not been *** To determine whether distal fixation to the second or third metacarpal *** Using a cadaveric radiocarpal dislocation model,the effect of distal fixation was studied in two stages:(1)A pilot study that investigated the effect of distal fixation alone;and(2)a more refined study that investigated the effect of described techniques for distal and proximal *** were measured in various parameters to determine the quality of the reduction *** The pilot study found that focusing on distal fixation alone without changing proximal fixation results in ulnar translocation and volar subluxation when fixing distally to the second metacarpal compared with the *** second iteration demonstrated that anatomic alignment in coronal and sagittal planes could be achieved with each *** In a cadaveric radiocarpal dislocation model,anatomic alignment can be maintained with bridge plate fixation to the second metacarpal or the third metacarpal if the described technique is *** considering dorsal bridge plate fixation for radiocarpal dislocations,the surgeon is encouraged to understand the nuances of different fixation techniques and how implant design features may influence proximal placement.

Feeding Calcium Salts of Linseed Oil on Metabolic Status and Reproductive Traits in Grazing Dairy Cows

引用

Open Journal of Animal Sciences 2024年第3期14卷 219-233页

This experiment aimed to evaluate the effect of calcium salts of linseed oil (rich in alpha-linolenic acid (ALA, C18:3n-3) on metabolic and reproductive traits in high-producing dairy cows under grazing. Thirty-six Holstein dairy cows were randomly assigned, in a complete block design, to receive ALA supplementation (0.85 kg∙day−1 of calcium salts of linseed oil) or to remain as untreated control (CON). The concentrate was formulated to offer the same amount of energy across treatments (CON cows received an extra kg of corn to compensate for the higher energy density of ALA treatment). A PMR + Alfalfa pasture was offered to all cows at the same time. A fixed time artiﬁcial insemination (FTAI) at 80 DIM, preceded by a Presynch plus Ovsynch protocol was implemented for the first service and later, on return to estrus, heat detection and artiﬁcial insemination (AI) were performed. Pregnancy diagnosis was checked at 30, 42, 60, and 90 d after AI. Blood and milk samples were taken biweekly. Treatment affected plasma cholesterol concentration (160.36 vs. 186.70 mg∙dl−1, p = 0.03, for ALA and CON, respectively) and on size of corpus luteum (CL, 17.6 vs. 13.7 mm, p = 0.02, for ALA and CON, respectively). Supplementation tended (p = 0.136) to increase conception rate by 200 DIM (81.69% vs. 55.43% in ALA and CON cows, respectively). However, treatment had no effect (p > 0.05) on body weight (BW), body condition score (BCS), and circulating levels of beta-hydroxybutyrate (BHBA), glucose, insulin, growth hormone (GH) and insulin-like growth factor (IGF-I). Our results suggest that supplementation with calcium salts of linseed oil could enhance ovarian function without affecting energy metabolism in early lactation dairy cows.

Randomized Clinical Study, Comparative of Parallel Groups, to Evaluate the Effectiveness of Three Preparations of Potassium Citrate in Producing an Increase in Urinary pH in Patients with a History of Kidney Stones

引用

Open Journal of Urology 2022年第9期12卷 459-470页

作者： eloy González R. Tellez Mendez Maria González Yibirín David Rincón Matute Policlinica Las Mercedes Caracas Venezuela Centro Clinico Prevaler Pampatar Venezuela Laboratorios LETI. S.A.V Guarenas Venezuela

Background: A very strict control of urinary pH is recommended to maintain it between 5.5 and 6.2, preventing formation or recurrence of crystals. Kidney stones are a common problem, with a high rate of recurrence, not altered by the success of surgery. Medical treatment prevents recurrence. Potassium Citrate inhibits crystallization of calcium salts. It influences calculogenesis by increasing urinary citrates and alkalinizing the urine. Purpose: to evaluate the similarity in the effect of three K citrate products, K citrate reference product Urocit®10 mEq, and K citrate from Laboratorios LETI S.A.V., 10 mEq and 15 mEq, on urinary pH. Materials and Methods: We carried out a prospective, randomized study of three parallel groups. We admitted female and male patients with history of kidney stones or evidence of lithiasis (grit, microlithiasis) in the renal echosonogram. Laboratory assessments: urine, 24-hour urine, urinary pH, Calcium, uric acid, Phosphorus, Sodium, protein and urinary creatinine at times: start, day 7, day 21, 30 of treatment. Results: all three products produced a slight increase in urinary pH in the simple urine test and 24-hour urine, with no differences between groups or their logarithmically transformed means and their CI95, which did not exceed the range between 80% and 125%. Conclusions: K Citrate, 10 mEq and 7.5 mEq, from Laboratorios LETI, S.A.V., at a dose of 30 mEq daily in patients with history of kidney stones are equivalent to the reference product Urocit®, in its effects on urinary pH in 24-hour urine, and in the simple urine test.
