ABSTRACT

The present study aimed to evaluate the effect of dry turmeric rhizomes on in vitro biogas production and diet fermentability. Turmeric rhizomes were included at gradually increased levels: 0, 0.5, 1, 1.5 and 2% of a diet containing per kg dr matter (DM): 500 g concentrate feed mixture, 400 g berseem hay and 100 g rice straw, and incubated for 48 h. Gas chromatography-mass spectrometry analysis showed that ar-turmerone, α-turmerone and ß-turmerone were the major bioactive compounds in the rhizomes. Turmeric rhizomes increased (p < 0.01) asymptotic gas production (GP) and rate and lag of CH4 production and decreased (p < 0.01) rate of GP, lag of GP, asymptotic CH4 production and proportion of CH4 production. Turmeric rhizome administration linearly increased (p < 0.01) DM and fiber degradability and concentrations of total short-chain fatty acids, acetic and propionic acids and ammonia-N and quadratically (p < 0.05) decreased fermentation pH. It is concluded that including up to 2% turmeric rhizomes improved in vitro ruminal fermentation and decreased CH4 production.

ABSTRACT

BACKGROUND: This study aims to evaluate the outcomes of using calcaneal plate in fixation of comminuted posterior wall (PW) acetabular fractures especially that have cranial (dome) or posterior extension (posterior column edge), and to evaluate its safety. To our knowledge, this is the first study that utilizes this off label implant technique in fixation of such fracture. METHODS: Twenty-two patients enrolled in the study with a minimum follow up of one year. After reducing the PW fragments sequentially, calcaneal plate was applied, fixing its distal part at ischial tuberosity upper ends using 3 screws in a triangular fashion, while its proximal part and radial wings were firmly fixed along the acetabular rim together with the classic longitudinal anchorage. Any fixation failure or head subluxation was recorded. RESULTS: Radiological outcome showed 18 cases scored as excellent, 2 were good, and 2 were poor. The functional outcome revealed 2 patients were excellent, 6 were very good and 14 were good. There was no loss of reduction or fixation failures throughout the follow up period. CONCLUSION: Calcaneal plate may offer an alternative method of fixation of comminuted PW fractures with acceptable radiological and functional results. Our study result may encourage the comprehensibility and replicability of this practice, however randomized multicentered studies should be conducted to validate this assumption. This method provides valuable trick strategy, stable and soft-tissue-friendly fracture fixation where modern implantations may be unavailable or of high cost. Calcaneal plates show some fascinating features that allow using them outside their field being flexible with large footprint area for fracture buttressing beside numerous hole choices with diverse paths providing suitable fixation, articular stability and wide zone of coverage in PW comminuted fracture patterns with cranial or posterior extensions. The plate proximal triangular configuration together with distal triangular screw fixation gives a stiff rigid anchorage and buttressing similar to a metal mesh covering and fixing any fragment numbers up to dome level.

ABSTRACT

INTRODUCTION: Numerous approaches were described for the management of Pipkin's type I fracture with no consensus on the "standard of care". The strategic thinking of the ideal access is through the medial approach. MATERIAL AND METHODS: Using Ferguson intermuscular interval, prospective study was done (January 2014-2019) to evaluate radiological and functional outcomes using HHS and Thompson-Epstein criteria. Fracture patterns were subclassified: anterior and posterior-inferior (AI/PI) requiring different reduction positions. RESULTS: Twenty-one patients (mean FU = 24.3 months (range, 12-48)) were divided into 14 (67.7%) AI and seven PI. Excision was performed in five (23.8%) (AI = 3 (14.3%) and PI = 2) and ORIF in 16 (AI = 11 (52.4%) and PI = 5). At the last follow-up, two (9.5%) were graded as excellent, 11 (52.4%) as good, three (14.3%) as fair, and five as poor. CONCLUSION: Modified Ludloff's approach provides safe easy direct access to fracture allowing easy excision or direct anatomical reduction, perpendicular compression, and rigid fixation with minimal complications.

ABSTRACT

High prices of corn grains due to their shortage in some regions force researcher to explore nonconventional alternatives. Therefore, the present study aimed to evaluate the effect of replacing corn grains at 25% (dry matter (DM) basis) with date press cake (DPC) without/with exogenous enzymes at 2 L/ton feed in diets of Barki sheep (24 rams divided as 6 rams/treatment) and Egyptian buffaloes (16 buffaloes divided as 4 buffalo/treatment). Each experiment was conducted under 4 treatments regime: control diet containing only corn grains, T1 diet where the control diet supplemented with exogenous enzyme, T2 diet where the control diet contained DPC on corn replacement (25% DM basis), and T3 diet where the control diet contained DPC on corn replacement (25% DM basis) along with exogenous enzyme supplement. The control diet contained concentrate feed mixture, corn silage, and rice straw at 50:40:10, respectively. Data on nutrient intake, digestibility, and nitrogen balance in sheep, as well as on blood parameters, milk production, and composition in buffaloes, were analyzed using the PROC GLM/MIXED procedure of SAS. The sheep under T2 and T3 treatments demonstrated greater digestibility of dry matter, organic matter, and neutral detergent fibers, along with improved nitrogen balance. The milk yield and its constituents were improved in the buffaloes under T3 treatment followed by those buffaloes under T2 and T1 treatments. This investigation could conclude that replacing corn grains with DPC at 25% (DM basis) in ruminant diets had beneficial effects on nutrients digestibility and milk yield along with its composition.

ABSTRACT

The objective of this study was to evaluate the effects of the inclusion of dried Salvia officinalis (SO) shrub leaves on nutrient degradability, ruminal in vitro fermentation, gas production (GP), methane (CH4), and carbon dioxide (CO2) productions. Dried and ground SO shrub leaves were included at 0% (control), 0.5%, 1%, 1.5%, and 2% DM of a diet consisting of (per kg DM) 500 g concentrate feed mixture, 400 g berseem hay, and 100 g rice straw. The diet was incubated for 48 h. The asymptotic GP and the rate of GP changed linearly and quadratically (p < 0.01), with the highest GP observed at 1% inclusion of SO and then decreasing thereafter with greater inclusion (i.e., 1.5% and 2%), while CH4 production and its rate decreased linearly (p < 0.01) with all levels of SO inclusion. A linear increase in CO2 production and its rate was also found with an increasing level of SO inclusion in the diet (p < 0.05). Furthermore, the degradability of DM, NDF, and the concentration of total short-chain fatty acids and acetate changed linearly and quadratically, with the greatest being found at 1% SO inclusion and then steadily declining after (p < 0.01) with the 1.5% and 2% inclusion levels. Meanwhile, the propionate, NH3-N, and microbial crude protein levels showed similar trends, with the plateau found at 1% inclusion of SO, where there was no change in butyrate concentration. Moreover, the pH, metabolizable energy, and partitioning factor (PF24) also changed linearly and quadratically (p < 0.05), where the pH and PF24 were considerably reduced and ME increased with a 1% inclusion of SO (p < 0.05). In summary, SO at 1% inclusion in the diet showed the potential to improve gas production kinetics, nutrient degradability, and the ruminal fermentation profile, with a more significant reduction in ruminal CH4 production suggesting that SO at 1% could be included in the ruminant diet to reduce their carbon footprint and increase the production performance.

ABSTRACT

Ruminants are considered a major producer of methane (CH4 ). Therefore, the present study aimed to determine the ability of dry fennel seeds to affect in vitro gas production and fermentation. Fennel seeds were included at 0% (Control), 0.5%, 1%, 1.5%, and 2% DM of a diet containing per kg DM: 500 g concentrate feed mixture, 400 g berseem hay, and 100 g of rice straw. The incubations lasted 48 h. Fennel seeds increased (P < 0.001) the asymptotic gas production and decreased its rate, while decreasing the production and proportion of CH4 (P < 0.05) and increased its rate. Moreover, fennel seed increased DM and neutral detergent fiber (P < 0.01) degradability, and increased total production of short-chain fatty acids, acetate, and propionate (P < 0.05). Compared to the control, fennel seeds increased (P < 0.01) metabolizable energy, partitioning factor, and microbial crude protein production. Overall, fennel seeds can be included up to 2% DM in ruminant diets as an environmentally friendly product in animal farming due to its ability to improve feed utilization, ruminal fermentation and while reducing CH4 production.

ABSTRACT

AIM: To assess radiological and functional outcomes of transilial internal fixator (TIFI) for treatment of sacral complete transforaminal fractures with a novel implantation technique that decrease wound irritation problems in addition to facilitating easy application of reduction methods beside showing the best entry points, screw trajectories and angles. METHODS: A Prospective case series from 2019 to 2021 was conducted at university hospital including 72 patients with Denis type 2 sacral fractures. The operative and fluoroscopy time, reduction, implantation techniques, postoperative radiological and functional data were collected and evaluated with minimum follow-up of 12 months. RESULTS: The mean initial fracture displacement was 4.42 mm while mean postoperative maximum residual fracture displacement was 2.8 mm, Radiological outcome assessed using Matta's grading at the final follow-up visit with 63 cases scored as Excellent,7 cases as Good, 2 cases as fair. Functional outcome using Majeed scoring shows 64 cases of Excellent grading and 8 cases were Good. Short operative and fluoroscopy time, easy reduction techniques, few skin problems were recorded. CONCLUSION: TIFI through a minimally invasive technique represents a valid method for dealing with transforaminal sacral fractures. TIFI provides a rigid fixation for posterior ring injuries with few risks regarding iatrogenic nerve injury, avoiding different variations of upper sacral osseous anatomy or sacral dysmorphism. In addition, there is no necessity for high quality fluoroscopy for visualization of sacral foramina intraoperatively, decreasing risk of radiation exposure, unlike other methods of fixation as iliosacral screws. Our novel modification for implantation technique provides few risks for postoperative and wound complications.

ABSTRACT

In the current paper, we review existing tools for solving variable selection problems in psychology. Modern regularization methods such as lasso regression have recently been introduced in the field and are incorporated into popular methodologies, such as network analysis. However, several recognized limitations of lasso regularization may limit its suitability for psychological research. In this paper, we compare the properties of lasso approaches used for variable selection to Bayesian variable selection approaches. In particular we highlight advantages of stochastic search variable selection (SSVS), that make it well suited for variable selection applications in psychology. We demonstrate these advantages and contrast SSVS with lasso type penalization in an application to predict depression symptoms in a large sample and an accompanying simulation study. We investigate the effects of sample size, effect size, and patterns of correlation among predictors on rates of correct and false inclusion and bias in the estimates. SSVS as investigated here is reasonably computationally efficient and powerful to detect moderate effects in small sample sizes (or small effects in moderate sample sizes), while protecting against false inclusion and without over-penalizing true effects. We recommend SSVS as a flexible framework that is well-suited for the field, discuss limitations, and suggest directions for future development.

ABSTRACT

PURPOSE: The aim of the study was to add to the literature new data regarding the evaluation of surgical fixation of challenging unstable paediatric pelvic fractures, radiologically and clinically besides recording any complications through the follow-up period. METHODS: Prospective study was conducted at our hospital between 2012 and 2017 where 21 patients less than 16 years with unstable fracture pelvis were surgically fixed. The method of fixation varied between the external percutaneous fixation and internal fixation. The Infix system was used in for anterior ring fixation in some cases. Patients were evaluated radiologically and functionally using the functional independence measure questionnaire (FIM) and the modified Merle d'Aubigne and Postel (MDP) score. RESULTS: Twelve males and 9 females were fixed with mean age of 12.5 years. Motorcar accident was the main mode of trauma. Nine patients had fracture pelvis Tile's type B and 12 had Tile's type C injuries. All fractures united by 8 weeks. No patients suffered from pelvic asymmetry or leg length discrepancy at a mean follow-up of 2 years. The mean of FIM was 122.5 and the mean of MDP score was 16.2. CONCLUSION: Displaced unstable pelvic fractures in children need a systematic evaluation of the injury pattern. These serious fractures should be referred for anterior ± posterior ring stabilization. Promising clinical outcomes with surgical fixation can be reached with a low rate of complications. Further large-scale studies should be conducted for the calling literature.

ABSTRACT

PURPOSE: Different reduction techniques and tools are described to facilitate anatomical reduction of acetabular fractures. However, maintenance of reduction, plate placement, and fracture fixation remain a challenge owing to the large surface area occupied by the available reduction tools. This study aims at radiological and functional assessment of the effectiveness of a novel reduction technique for the posterior column element in displaced acetabular fractures. METHODS: A prospective study was conducted for evaluation of a novel reduction technique; the use of the conventional large holding Verbrugge forceps for reduction of posterior column and transverse, with or without posterior wall, fractures. Intra-operative safety and reduction time were evaluated. The immediate postoperative quality of reduction was assessed using Matta radiographic criteria. The functional outcome was evaluated at the latest follow-up visit using the modified Merle d'Aubigne and Postel (MDP) score. RESULTS: Thirty patients with a mean follow-up of 18.1 months were included. Fifteen had transverse/posterior wall, ten had transverse, and five had posterior column fractures. All fractures were displaced ≥ 2 mm on anteroposterior and/or Judet views of the pelvis without traction. The average operative time was 100.4 min with 12.5 min reduction time. No intra-operative complications were encountered. Twenty-three patients (76.6%) had anatomical while seven (23.3%) had imperfect reduction. The functional outcome score was excellent in three patients, good in 18, fair in four, and poor in five patients at the latest follow-up. CONCLUSION: The use of the conventional large Verbrugge bone-holding forceps for the reduction of the posterior column element in displaced acetabular fractures using the Kocher-Langenbeck approach is a safe, effective, time-saving, and technically undemanding procedure.

ABSTRACT

BACKGROUND: Planovalgus deformity of the foot is common among cerebral palsy (CP) patients. It is an upcoming topic with debate and controversy that require further studies. Many clinical studies involving arthroereisis have shown acceptable results in short- and mid-term follow-up. The aim of this work was to evaluate the outcome of arthroereisis using a conventional screw placed percutaneously across the talocalcaneal articulation for the treatment of moderate planovalgus deformity in children with CP. METHODS: Between 2015 and 2018, a prospective study was conducted including 23 CP patients with bilateral flexible planovalgus deformity with follow-up period ranging from 24 to 40 months (mean of 36.7 months). The radiological and clinical outcomes were assessed. The patient/parent outcome was evaluated using the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C). RESULTS: The results showed statistically significant improvement in both radiological and clinical data as well as patient's symptoms and parent's satisfaction. CONCLUSION: Results obtained from literature from the past decades after arthroereisis for the correction of moderate planovalgus deformity in CP patients are promising. The few studies reported on that procedure shared the same harmony with our study giving a chance to be a good alternative to joint destructive procedures. Our technique is simple, effective, economical, and minimally invasive if used in selected pediatric CP patients. LEVELS OF EVIDENCE: Therapeutic, Level IV.

ABSTRACT

Pelvic fractures are uncommon in children and account for between 0.3 and 7.5% of all pediatric injuries. Open pelvic fractures only account for up to 12.9% of all pediatric pelvic fractures. An unusual case of open complete anterior sacro-iliac joint dislocation in a 4-year-old boy is presented with a long-term follow-up. The multidisciplinary approach is reported with review of the current literature. A 4-year-old male presented to our institution in January 2012 after having been run over by a tractor. He presented with gross hemodynamical instability, MISS of 25, and an unstable lateral compression type III pelvic fracture with complete anterior dislocation of the left hemipelvis and a groin wound extending into the left thigh. The patient was managed in accordance with the ATLS and open fracture guidelines. Reduction in the dislocated SI joint was achieved via a posterior approach to the SI joint, followed by fixation with 2K wires in S1 and S2 sacral segments, with an anterior external fixator. Pelvic asymmetry post-reduction was 0.9 cm, compared to 16 cm post-injury, and asymmetry persisted till final follow-up at 5 years. At 5 years, patient regained full function, including recreational sport activities. Patients scored a 96/96 on the Majeed score (after excluding 4 points for sexual function). We believe that posterior reduction in an anteriorly dislocated SI joint in the pediatric population is a viable option. A coordinated, multidisciplinary approach and restoration of pelvic ring stability can lead to optimal outcome.

ABSTRACT

INTRODUCTION: Biomechanical studies have compared fixation methods in transverse acetabular fractures, yet there is not enough clinical data to suggest an optimal fixation method. The aim of this randomized controlled trail was to compare fracture stability in posterior plating alone versus posterior plating and anterior column lag-screw fixation in treatment of transverse and transverse with posterior wall acetabular fractures. METHODS: Thirty patients were randomized to one of two groups, either posterior fixation alone (single column group), or posterior plating and anterior fixation with percutaneous anterior column screw (double column group). Patients were followed up with serial radiographic assessments documenting any loss of reduction, utilizing Matta's radiological criteria, measuring the roof arc angles and by measuring any change in the femoral head offset. RESULTS: Fifteen patients were randomized to each group. Mean patient age was 31 years, mean follow up period was 19 months (range 12-24). There was no significant differences between the two groups with regards the quality of post-operative reduction, blood loss, hospital stay and functional score using the modified Merle D'Aubinge and Postel score. The operative time was significantly longer in the double column fixation group (130 min versus 104 min). There was no loss of reduction observed in either of the two groups. CONCLUSION: Single poster column fixation in transverse and transverse posterior wall fractures showed similar result to double column fixation, in terms of fractures stability in the follow up period, quality of reduction and early functional outcome.
