The present study was designed to assess the impact of dietary supplementation of lemongrass essential oil (LGEO) on growth performance, carcass traits, liver and kidney function, immunity, antioxidant indices and caecal microbiota of growing quail. A total of 200 Japanese quails at 1-week-old were haphazardly allotted to 5 groups of 40 chicks in five replicates (8 per replicate). The first group was the control group, while LGEO was added at levels of 150, 300, 450, and 600 mg/kg diet in the 2nd, 3rd, 4th and 5th groups, respectively. Dietary supplementation of LGEO (150, 300 and 450 mg/ kg diet) increased body weight at 3 and 5 wk of age, and increased body weight gain during all periods compared with the control group (P < 0.05). All levels of LGEO improved feed conversion ratio during the periods from 1 to 3 and 1 to 5 wk of age. During 3 to 5 wk, feed conversion ratio was improved in quails fed LGEO (300 and 450 mg/kg diet) compared with the control and other treatments. Carcass traits, plasma globulin, alanine aminotransferase, and urea values did not differ among the treatments (P > 0.05), but the activity of aspartate aminotransferase in the plasma was significantly decreased (P < 0.05) in LGEO-treated groups. The total protein and albumin values were significantly increased (P < 0.05) in quails fed levels of LGEO (except 600 mg/kg diet) compared with the control. The inclusion of LGEO in quail diets improved (P < 0.05) plasma lipid profile. The dietary supplementation of LGEO increased (linear and quadratic, P < 0.05) plasma immunoglobulins (IgM, IgG, and IgA) levels, lysozyme values and activities of superoxide dismutase, total antioxidant capacity, reduced glutathione and catalase compared with the control group. The caecal Coliform, E. coli and Salmonella were lowered (P < 0.0001) in the quails treated with all LGEO levels, but the total bacterial count and Lactobacillus count were increased with dietary supplementation of LGEO levels (300 and 450 mg/kg) compared with those in the control group. The activities of digestive enzymes were significantly higher in birds fed the diet supplemented with LGEO levels than those fed the control diet. In conclusion, dietary supplementation of LGEO can improve the performance, lipid profile, immunity and antioxidant indices and decline intestinal pathogens and thus boost the health status of growing quail.

Date ( L.) by-Products: Chemical Composition, Nutritive Value and Applications in Poultry Nutrition, an Updating Review.

Animals (Basel) 2021 Apr 15;11(4). Epub 2021 Apr 15.

Several by-products, such as whole cull dates, date stones (also called pits, seeds, kernels), sugar-extracted date pulp, are produced from date fruit processing industries. These by-products, particularly date stone meal represent 10 to 20% of the whole dates are wasted, causing environmental issues. However, the date stone is rich in various nutrients, such as nitrogen-free extract, fiber, fat, and minerals, which could be used as an alternative feed source in poultry nutrition. However, the high fiber content in date stone meal restricts its use in poultry diets. Whole date wastes and date pulp have lower protein, fiber and fat content than those in date stone meal. Several studies have investigated the use of date stone meal and other by-products as a replacement of dietary corn and barley on feed intake, growth, feed efficiency, and nutrient utilization in poultry. The compilation of results obtained from different studies indicates that date fruit by-products, particularly date stone meal, could be incorporated up to 10% levels, replacing corn or barley grains without hampering production performance, and this could reduce the production cost. Moreover, the use of date stone meal at lower levels (5-10%) sometimes shows better growth performance, probably due to the presence of bioactive principles such as antioxidants and phenolic compounds. The use of date stone meal in poultry diets may be practically important under certain circumstances not only under the COVID-19 crisis due to the lockdown of airports, dry ports, ports and traffic restrictions, but also in countries with a limited supply of classical feed resources and which depend on imported ones. Finally, it can recommend that using date stone meal (DSM) up to 5-10% in poultry diets positively affect the productive performance. Due to the variability in the nutritive value of the DSM, developing a formula for metabolizable energy (ME) of DSM = a (intercept) - b (slope) × crude fiber (CF) content should be considered to improve the precision of feed formula for poultry. However, the nutritional value of DSM might not only depend on crude fiber but also on other compounds.

Management of a Severe Degloving Injury With a Type 2 Open Tibia Fracture Using Negative Pressure Wound Therapy With Instillation and Dwell Time.

Wounds 2020 Dec;32(12):E110-E113

Department of Orthopedic Surgery and Trauma, Regional Hospital of Orleans, Orleans, France.

Introduction: Severe lower extremity trauma cases are challenging for most orthopedic surgeons if a degloving injury with open fracture is associated, especially in the elderly population. The management of the soft tissue is essential for bone union and reduction of infection.

Case Report: The authors present the case of an 87-year-old female admitted to their department after a road accident in which she sustained an open fracture of the distal tibia classified as Gustilo-Anderson Type II, a closed fracture of the lateral malleoli, and a degloving of the posterior and lateral aspect of the left leg. After antibiotic delivery, she underwent surgical debridement and wound irrigation, 5 hours after the accident. The avulsed skin flap was conserved, the fracture of the lateral malleoli was fixed using the minimally invasive plate osteosynthesis technique, and an external fixation was applied for the distal tibia fracture. After 1 week, the necrotic skin flap and muscle were excised, and negative pressure wound therapy with instillation and dwell time (NPWTi-d) was applied for 9 days. Once granulation tissue with healthy wound edges was obtained, a split-thickness skin graft was used to provide total coverage. After 8 weeks, external fixation was replaced by a plaster cast. Eight weeks later, all wounds and fractures were healed, and the patient was able to return to their daily activities.

Conclusions: The authors' main goal was achieved: preserving the architecture of the leg, achieving bone union, and avoiding infection. A large part of this good result comes back to NPWTi-d, a promising treatment that grants clinical benefit for the patient and surgeon. Additional research and larger prospective studies are required before giving a strict recommendation.

Negative Pressure Wound Therapy With Instillation and Dwell Time Used to Treat a Complex Open (Terrible Triad) Injury of the Elbow: A Case Report.

Wounds 2020 Dec;32(12):E126-E129

Department of Orthopedic Surgery and Trauma, Regional Hospital of Orleans, Orleans, France.

Introduction: Treating a complex elbow injury known as the terrible triad, combined with a severe soft tissue trauma, is challenging for most orthopedic surgeons and can lead to permanent disabilities and poor functional outcomes if reconstruction is inadequate.

Case Report: A 75-year-old male with a history of high blood pressure was injured in an accident involving agricultural equipment and presented with a triad injury of the left elbow: a posterolateral dislocation combined with fractures of the radial head (Mason-Johnson Type II) and ulnar coronoid process (Morrey Type 1). Fractures to the radial head and ulnar coronoid process and injuries to the lateral collateral ligament and triceps tendon were repaired, and a local skin flap was preserved to provide adequate soft tissue coverage. A hinged external fixator was applied to maintain elbow alignment and allow early mobilization. Traditional negative pressure wound therapy (NPWT) was applied on the remaining skin defects; when local necrosis and septic arthritis of the elbow were noted, NPWT with instillation and dwell time (NPWTi-d) was initiated. Once a viable wound bed was obtained, a split-thickness skin graft was used to provide total coverage. All wounds and fractures were healed within 8 weeks, the external fixator was removed, and free elbow joint mobilization was allowed. At 3 months, the authors obtained 100°/30°/0° of elbow range of motion with a DASH 3 at 30. At 6 months, the elbow range of motion reached 120°/20°/0° with a clear improvement of DASH score (DASH 6 at 14.2).

Conclusions: Management of this complex elbow injury that featured NPWTi-d contributed to a good result and facilitated coverage of an extensive loss of skin and soft tissue; more importantly, the patient experienced limited discomfort. A larger prospective study is required to support general recommendations for this approach to similar injury.

Management of a High-Energy Soft Tissue Injury of the Lower Extremity Using Negative Pressure Wound Therapy With Instillation and Dwell Time and a Reticulated Open Cell Foam Dressing.

Wounds 2020 Dec;32(12):375-377

Department of Orthopedic Surgery and Trauma, Regional Hospital of Orleans, Orleans, France.

Introduction: Soft tissue injuries of the lower extremity are the result of high-energy trauma, such as road accidents, and remain challenging for most orthopedic surgeons. Proper selection of the treatment is important considering the risk of delayed necrosis and wound sepsis. Negative pressure wound therapy (NPWT) has improved complex wound treatment since 1997, but all treatments present advantages and limits.

Case Report: A 21-year-old male presented with a high-energy soft tissue injury of the lower extremity. Three days after surgical debridement, complete skin necrosis developed. Successive surgical debridement was done in combination with traditional NPWT for 2 weeks; yet the wound did not progress toward healing, and the bone remained exposed. Negative pressure wound therapy with instillation and dwell time (NPWTi-d) was used with a novel reticulated open cell foam dressing (ROCF-CC) because further surgical debridement was not possible, and the use of NPWT was not recommended by the French high authority for health. Growth of granulation tissue was fast (9 days), even over the bone, without any surgical debridement and despite the presence of nonviable and fibrinous tissue. After that, traditional NPWT was discontinued and a split-thickness skin graft then was used to cover the defects. Four weeks following the accident, all wounds were completely healed.

Conclusions: Surgical debridement remains irreplaceable; however, when debridement is not feasible, NPWTi-d with ROCF-CC might be the treatment of choice. This strategy allowed the authors to ensure coverage of an extensive loss of soft tissue when the traditional NPWT limit was reached.
