Facial reconstruction and augmentation, integral in facial plastic surgery, address defects related to trauma, tumors infections, and congenital skeletal deficiencies. Aesthetic considerations, including age-related facial changes, involve volume loss and diminished projection, often associated with predictable changes in the facial skeleton. Autologous, allogeneic, and alloplastic implants are used to address these concerns. Autologous materials such as bone, cartilage, and fat, while longstanding options, have limitations, including unpredictability and resorption rates...

With the widespread use of direct oral anticoagulants (DOACs), there is an urgent need for a rapid assay to exclude clinically relevant plasma levels. Accurate and rapid determination of DOAC levels would guide medical decision-making to (a) determine the potential contribution of the DOAC to spontaneous or trauma-induced hemorrhage; (b) identify appropriate candidates for reversal, or (c) optimize the timing of urgent surgery or intervention. The DOAC Dipstick test uses a disposable strip to identify factor Xa- or thrombin inhibitors in a urine sample...

This systematic review evaluated preclinical studies to assess whether PBM has a more favorable histological response than other treatments used before delayed replantation of avulsed teeth. This review followed the PRISMA checklist and was registered in PROSPERO. MEDLINE (PubMed), Embase, Scopus and Web of Science were searched from their inception to July 14, 2022. Data were independently extracted by two reviewers. Data were collected about species, number of animals, number and type of teeth, groups evaluated, extra-alveolar time, parameters for PBM and other study groups, presence and characteristics of containment, observation time points, evaluation methods, characteristics evaluated, and significant results...

Large bone reconstruction following trauma poses significant challenges for reconstructive surgeons, leading to a healthcare burden for health systems, long-term pain for patients, and complex disorders such as infections that are difficult to resolve. The use of bone substitutes is suboptimal for substantial bone loss, as they induce localized atrophy and are generally weak, and unable to support load. A combination of strong polycaprolactone (PCL)-based scaffolds, with an average channel size of 330 µm, enriched with 20% w / w of hydroxyapatite (HA), β-tricalcium phosphate (TCP), or Bioglass 45S5 (Bioglass), has been developed and tested for bone regeneration in a critical-size ovine femoral condyle defect model...

Many aspects of the impact of childhood trauma remain unknown, such as the age at which individuals are most vulnerable to trauma, whether traumatic experiences have more severe and lasting effects when experienced early in life, and whether early life trauma causes psychiatric conditions such as anxiety and major depressive disorder (MDD) that persist over time or evolve into other disorders. Thus, this study aimed to investigate the impact of traumatic experiences in childhood on susceptibility to mood disorders in adulthood, particularly MDD...

Poly-victimization is often reported by formerly incarcerated women and leads to physical and mental health problems that interfere with daily functioning, sustained employment, and housing stability. Although reentry programs exist, few focus on the physical and emotional impact of multiple traumas. Passport to Freedom (P2F), a woman-centered, trauma-informed reentry program, was developed to support formerly incarcerated women. The pilot intervention, performed in 2017, focused on the connections between trauma and health, coping with symptoms, and managing one's own health...

BACKGROUND: Immunological disorder remains a great challenge in severe poly-trauma, in which lymphopenia is an important contributor. The purpose of present study is to explore whether ferroptosis, a new manner of programmed cell death (PCD), is involved in the lymphocyte depletion and predictive to the adverse prognosis of severe injuries. PATIENTS AND METHODS: Severe polytrauma patients admitted from January 2022 to December 2022 in our trauma center were prospectively investigated...

Autotransplanted teeth in the maxillary anterior region should be restored or reshaped as soon as possible for functional and esthetic reasons as well as the well-being of the patient. However, such tooth restorations are frequently not carried out immediately after tooth transplantation because the process could have a negative impact on the healing process. The development of a simple, immediate, and atraumatic esthetic interim restoration would be of great benefit to both the clinician and patient and address all the concerns caused by immediately preparing the tooth postoperatively and cementing a permanent restoration...

OBJECTIVES: Infection is still the leading cause of morbidity and mortality among burn patients worldwide. Isolation and identification of pediatric burn wound bacterial colonizers can prevent infection and improve burn trauma treatment. In this study, we explored early microbial colonizers within the burn wounds and the susceptibility of those isolates to antibiotics among hospitalized pediatric patients with minor and moderate burns, clinically significant infections and outcomes. METHODS: A retrospective analysis of pediatric patients admitted to the inpatient pediatric surgical ward and treated for minor and moderate burns from 2009 to 2018 was performed...

Improved materials for peripheral nerve repair are needed for the advancement of new surgical techniques in fields spanning from oncology to trauma. In this study, we developed bioresorbable materials capable of producing repeated electric field gradients spaced 600 μm apart to assess the impact on neuronal cell growth, and migration. Electrically conductive, biphasic composites comprised of poly (glycerol) sebacate acrylate (PGSA) alone, and doped with poly (pyrrole) (PPy), were prepared to create alternating segments with high and low electrically conductivity...

Biomedical implants remain an important clinical tool for restoring patient mobility and quality of life after trauma. While polymers are often used for devices, their degradation profile remains difficult to determine post-implantation. CT monitoring could be a powerful tool for in situ monitoring of devices, but polymers require the introduction of radiopaque contrast agents, like nanoparticles, to be distinguishable from native tissue. As device function is mediated by the immune system, use of radiopaque nanoparticles for serial monitoring therefore requires a minimal impact on inflammatory response...

Successfully reconstructing bone and restoring its dynamic function represents a significant challenge for medicine. Critical size defects (CSDs), resulting from trauma, tumor removal, or degenerative conditions, do not naturally heal and often require complex bone grafting. However, these grafts carry risks, such as tissue rejection, infections, and surgical site damage, necessitating the development of alternative treatments. Three-dimensional and four-dimensional printed synthetic biomaterials represent a viable alternative, as they carry low production costs and are highly reproducible...

Burns are among the most common causes of trauma worldwide. Reducing the healing time of deep burn wounds has always been a major challenge. Traditional dressings not only require a lengthy medical procedure but also cause unbearable pain and secondary damage to patients. In this study, we developed an exudate-absorbing and antimicrobial hydrogel with a curcumin-loaded magnesium polyphenol network (Cur-Mg@PP) to promote burn wound healing. That hydrogel was composed of an ε-poly-l-lysine (ε-PLL)/polymer poly(γ-glutamic acid) (γ-PGA) hydrogel (PP) and curcumin-loaded magnesium polyphenol network (Cur-Mg)...

Maternal infection during pregnancy and childhood social trauma have been associated with neurodevelopmental and affective disorders, such as schizophrenia, autism spectrum disorders, bipolar disorder and depression. These disorders are characterized by changes in microglial cells, which play a notable role in synaptic pruning, and synaptic deficits. Here, we investigated the effect of prenatal infection and social adversity during adolescence - either alone or in combination - on behavior, microglia, and synaptic density...

Massive bleeding and wound infection due to severe traumas pose a huge threat to the life and health of sufferers; therefore, it is of clinical importance to fabricate adhesives with rapid hemostatic and superior antibacterial capabilities. However, the weak wet adhesion and insufficient function of existing bioadhesives limits their practical application. In this study, a sandcastle worm protein inspired polyelectrolyte self-coacervate adhesive of poly-γ-glutamic acid (PGA) and lysozyme (LZM) was developed...

A systematic review was performed to compare adverse maternal and neonatal outcomes among pregnant patients with gunshot wounds (GSW) to the abdominopelvic vs other region(s) at <u>></u> 20 weeks gestation. A search of Medline Ovid, Elsevier Embase, EBSCO CINAHL, and Cochrane Library in July 2022 and reference searches resulted in 1742 studies, which were screened. The 41 included studies reported outcomes for 59 pregnant patients with GSW, of which 31 (52.5%) had an isolated abdominopelvic GSW and 28 (47...

Rapid post-wound closure is necessary to avoid wound infection and promote scar-free healing when skin trauma occurs. In this study, new types of hydrogel dressings with adjustable contractility were fabricated based on N -isopropyl acrylamide/sodium alginate/graphene oxide (P/SA/GO). Then, the chitosan (CS) solution was used as a bridging polymer to achieve tissue adhesion to the hydrogel. The results show that the hydrogel based on poly( N -isopropyl acrylamide) (PNIPAM) not only has the ability to self-shrink but also can adjust the rate of shrinkage through near-infrared thermal stimulation...

BACKGROUND: The management of pelvic fractures is a significant challenge. Surgical site infection can result in the need for revision surgery, cause functional impairment, and lead to a prolonged length of stay and increased treatment costs. Although reports on fracture-related infection (FRI) after pelvic fracture fixation are sparsely reported in the literature, it is a serious complication. This study analysed patients with FRIs after pelvic fracture regarding patient characteristics, treatment strategies, and an evaluation of risk factors for FRI...

BACKGROUND: This study aimed to explore the effect of a nanomaterial-based miR-320a inhibitor sustained release system in trauma-induced osteonecrosis of the femoral head (TIONFH). METHODS: The miR-320a inhibitor-loaded polyethylene glycol (PEG)- Poly(lactic-co-glycolic acid) (PLGA)- Poly-L-lysine (PLL) nanoparticles were constructed using the double emulsion method. The TIONFH rabbit model was established to observe the effects of miR-320a inhibitor nanoparticles in vivo...

OBJECTIVE: Numerous studies have reported executive function differences among victims of childhood sexual abuse.
