CD300a blockade enhances efferocytosis by infiltrating myeloid cellular material and ameliorates neuronal debts following ischemic cerebrovascular event.
Pelvic injuries often result from high-energy trauma and lead to significant functional impairment. While the physical outcomes of these injuries have been widely studied, the psychological consequences remain largely unexplored. The purpose of this study was to examine psychosocial and functional outcomes of patients with pelvic trauma in the year after injury. The sample (N = 32) consisted of adult patients with traumatic pelvic injures, as defined by ICD-9 codes, who were admitted to a Level I Trauma Center for at least 24 h. Participants were primarily female (53%) with a mean age of 48.7 years (SD = 17.9). Demographic, injury-related, and psychosocial data (e.g., posttraumatic stress disorder (PTSD), depression, alcohol use, quality of life, pain, return to work) were gathered at the time of hospitalization as well as at 3-, 6-, and 12 month follow-ups. Mixed regression models were used to examine the outcome variables over time. There were significant decreases in pain and alcohol use at each follow-up compared to baseline. However, despite the decrease, the levels of pain and alcohol use remained high. Physical and mental health also decreased significantly, indicating worsened functioning and lowered quality of life. Neither PTSD nor depression changed significantly over time, indicating that participants' symptoms were not likely to improve. These data suggest that sustaining a traumatic pelvic injury increases the risk of diminished quality of life, both mentally and physically. Even one-year post-injury, participants experienced moderate physical pain and higher levels of PTSD, depression, and problematic alcohol use than would be expected in the general population. These findings highlight the need for an interdisciplinary approach to treating patients with pelvic injuries, including psychological screening and intervention in acute care and throughout recovery. Poincianella pluviosa has already been described as capable of healing skin wounds. In an attempt to prolong contact of the drug with the wound, it was proposed in this study to evaluate wound healing using a crude extract (CE) of P. pluviosa incorporated in carboxymethylcellulose polymer films. The chromatographic profile of the semipurified fraction of P. pluviosa was evaluated by ultra-high performance liquid chromatography (UHPLC), confirming the compounds gallic acid, geraniin, and ellagic acid. The films were evaluated for their physical and mechanical properties, water vapor permeability, moisture absorption capacity, and FTIR spectroscopy. For in vivo experiments, wounds were made on the back of rats and treated daily for 4, 7, 10, or 14 days with film containing CE or control film. At the end of each period, skin permeation analysis and histological analysis were made using re-epithelialisation, cell proliferation, and collagen formation. Statistical significance was determined by GraphPad Prism using t test and Mann-Whitney test. Anti-staphylococcal activity was evaluated with standard strains of Staphylococcus aureus, methicillin-resistant, and coagulase negative. It was demonstrated that the presence of CE in the films increased the capacity to absorb water and decreased resistance and permeability. The CE of the film permeated the skin, reaching the dermis and was able to influence re-epithelisation, cell proliferation, and collagen formation. Satisfactory results were observed against S. aureus strains, particularly coagulase negative. Films with CE of P. pluviosa can be an alternative in the wound healing, protecting against opportunistic infections and giving comfort to the patient. AIM The aim of the research was to determine the smallest amount of loading on the lunate bone obtained by gradually shortening the radius in different ulnar variants as the potential treatment of Kienböck's disease. METHODS The research was conducted on anatomic preparations of 20 upper extremities using only the distal part of the forearm and hand, placing them in exactly defined positions. A Fuji Prescale film was inserted in the open radiocarpal joint to measure pressure after compressing axially by changing the length of forearm in four stages by the gradual shortening of the radius. RESULTS The greatest reduction of average pressure on the lunatum achieved by shortening the radius depended on ulnar variant. read more In ulnar variant 0, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 3 mm (24% reduction). For ulnar variant -1, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 2 mm (37% reduction). For ulnar variants -2, -3 and +1, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 3 mm (5%, 75% and 9% respectively). CONCLUSIONS The pressure distribution in the distal radiocarpal joint is vital for healing, and shortening of the radius relieves the pressure on the lunate bone. The exact type of surgery and the amount of radial osteotomy depends on preoperative ulnar variant. The available scores to clinically evaluate fracture consolidation encounter difficulties to interpret progression towards consolidation in long-bone non-union, particularly when incorporating biomaterials in the surgical treatment. The aims of this study were to validate the REBORNE bone healing scale in tibia, humerus and femur non-unions treated by a combination of mesenchymal stromal cells (MSCs) and biomaterials, through the interclass correlation (ICC) among raters, and to define reliability and concordance in anteroposterior and lateral radiographs, compared to computed tomography (CT). METHODS Twenty-six cases from the EudraCT 2011-005441-13 clinical trial underwent bone healing evaluation, if at least 3 out of 4 cortical views clearly identified. Three senior orthopaedic surgeons evaluated radiographs and CTs at 3 and 6 months FU. All cases included preoperative imaging and radiographs at 12 months. The 4-stage scale score was obtained from each cortical view in orthogonal radiographs or CTs. A scoreidation in 77%, with an accuracy of 83% based on ROC curves. CONCLUSIONS The REBORNE score measured with CT or radiographic images was reliable among raters at a follow-up time above 6 months for long bone non-union fractures. The REBORNE scale measured with radiographs proved valid to assess consolidation against CT measurements.
