OBJECTIVE: Numerous studies have reported executive function differences among victims of childhood sexual abuse. This case study aims to expand upon the existing literature on the intersection of neuropsychological symptoms and trauma from childhood sexual abuse. METHOD: We present a case of an 18-year-old white woman with a history of sexual trauma and deficits in executive functioning. She first demonstrated deficits in executive functioning at age 10, around the beginning of her sexual abuse...

Background : There is a lack of consensus among researchers on the association between shyness and substance use. This may be due to unexamined modifiers of this association, such as childhood victimization. Objective : The purpose of this study was to examine if experiencing different types of victimization (emotional, physical, sexual, and poly-victimization) modifies the association between shyness and substance use outcomes in adults. In this study, we performed moderation analyses to investigate whether victimization moderates the association between shyness and substance use/abuse...

New bone repair materials are needed for treatment of trauma- and disease-related skeletal defects as they still represent a major challenge in clinical practice. Additionally, new strategies are required to combat orthopedic device-related infections (ODRI), given the rising incidence of total joint replacement and fracture fixation surgeries in increasingly elderly populations. Recently, the convergence of additive manufacturing (AM) and bone tissue engineering (BTE) has facilitated the development of bone healthcare to achieve personalized three-dimensional (3D) scaffolds...

Bioinspired hydrogels have demonstrated multiple superiorities over traditional wound dressings for wound healing applications. However, the fabrication of bioinspired hydrogel-based wound dressings with desired functionalities always requires multiple successive steps, time-consuming processes, and/or sophisticated protocols, plaguing their clinical applications. Here, a facile one-pot strategy is developed to prepare a skin-inspired multifunctional hydrogel within 30 min by incorporating elastin (an essential functional component of the dermal extracellular matrix), tannic acid, and chitosan into the covalently cross-linked poly(acrylamide) network through noncovalent interactions...

Critical-size skull defects caused by trauma, infection, and tumor resection raise great demands for efficient bone substitutes. Herein, a hybrid cross-linked hierarchical microporous hydrogel scaffold (PHCLS) was successfully assembled by a multistep procedure, which involved (i) the preparation of poly(lactic- co -glycolic)/nanohydroxyapatite (PLGA-HAP) porous microspheres, (ii) embedding the spheres in a solution of dopamine-modified hyaluronic acid and collagen I (Col I) and cross-linking via dopamine polyphenols binding to (i) Col I amino groups (via Michael addition) and (ii) PLGA-HAP (via calcium ion chelation)...

Dissociative disorders (DDs) are characterized by a discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, bodily representation, motor control, and action. The life-threatening coronavirus disease 2019 (COVID-19) pandemic has been identified as a potentially traumatic event and may produce a wide range of mental health problems, such as depression, anxiety disorders, sleep disorders, and DD, stemming from pandemic-related events, such as sickness, isolation, losing loved ones, and fear for one's life...

INTRODUCTION AND IMPORTANCE: Poly-trauma is among the top ten leading causes of mortality and morbidity in developing countries. Road traffic injuries are the major cause of mortality in the overall burden of deaths related to injuries. The aim of this publication is to show how important are the principles of management in saving life even in austere limited resource settings. CASE PRESENTATION: We herein present a case of a 17-year-old male who presented to our emergency department about an hour after being involved in motor traffic accident in a semiconscious state, in hypovolemic shock and sustained multiple injuries...

The current review examined the influence of psychosocial factors on adolescents' perinatal anxiety (PA) and perinatal depression (PND) across geographical regions. Three databases were searched for articles published between 2017 and 2022 and 15 articles were reviewed. We categorized factors into social, cultural, and environmental domains. Social factors included adolescent caregiver trust/attachment, social support, perceived social support, trauma/poly-traumatization, and peer solidarity. Cultural factors included feelings of shame, marital satisfaction, partner's rejection of pregnancy, lack of parental involvement in care, parenting stress, childhood household dysfunction, and adverse childhood events...

PURPOSE: To explore gender differences of the associations between childhood adversity (CA) subtypes and psychiatric symptoms in the general population. METHODS: Data of 791 participants were retrieved from a general population twin cohort. The Symptom Checklist-90 Revised (SCL-90) and the Childhood Trauma Questionnaire were used to assess overall psychopathology with nine symptom domains scores and total CA with exposure to five CA subtypes, respectively. The associations between CA and psychopathology were analyzed in men and women separately and were subsequently compared...

Postoperative abdominal adhesion is a very common and serious complication, resulting in pain, intestinal obstruction and heavy economic burden. Post-injury inflammation that could activate the coagulation cascade and deposition of fibrin is a major cause of adhesion. Many physical barrier membranes are used to prevent abdominal adhesion, but their efficiency is limited due to the lack of anti-inflammatory activity. Here, an electrospinning membrane composed of poly(lactic- co -glycolic acid) (PLGA) providing support and mechanical strength and chondroitin sulfate (CS) conferring anti-inflammation activity is fabricated for preventing abdominal adhesion after injury...

OBJECTIVE: NovoSorb (Poly-Novo Ltd, Australia) biodegradable temporising matrix (BTM) is a novel artificial dermal matrix. Previous literature is weighted towards its use in burns reconstruction; however, this paper describes its use within a range of wound aetiologies. The authors present one of the largest and most diverse case series to date, and aim to provide an independent benchmark of clinical practice. METHOD: A retrospective observational study was performed...

Bone is one of the most complex, inaccessible body structures, responsible for calcium storage and haematopoiesis. The second highest cause of death across the world is cancer. Amongst all the types of cancers, bone cancer treatment modalities are limited due to the structural complexity and inaccessibility of bones. The worldwide incidence of bone diseases and bone defects due to cancer, infection, trauma, age-related bone degeneration is increasing. Currently different conventional therapies are available for bone cancer such as chemotherapy, surgery and radiotherapy, but they have several disadvantages associated with them...

BACKGROUND: Childhood trauma is a risk factor for psychosis. It is proposed this is due to traumatic events giving rise to psychological mechanisms that are implicated in the development and maintenance of symptoms. Investigation of the psychological mechanisms accounting for relationships between trauma and psychosis will be assisted by focusing on specific trauma profiles, hallucination modalities, and delusion subtypes. STUDY DESIGN: In 171 adults with schizophrenia-spectrum diagnoses and high-conviction delusions, associations between childhood trauma classes, and hallucination and delusion factors, were tested using structural equation models (SEMs)...

People with dissociative symptoms are generally poly-symptomatic and require high levels of healthcare resources. Post-traumatic stress disorder (PTSD) and depressive symptoms are two major disabling comorbid symptoms in people with dissociative symptoms. While the sense of control over symptoms may be associated with PTSD and dissociative symptoms, the interplay among these factors over time remains unexplored. This study examined the predictors of PTSD and depressive symptoms in people with dissociative symptoms...

Wound dressing with poor antibacterial properties, the tendency to adhere to the wound site, poor mechanical strength, and lack of porosity and flexibility are the major cause of blood loss, delayed wound repair, and sometimes causes death during the trauma or injury. In such cases, hydrogel-based antibacterial wound dressing would be a boon to the existing dressing as the moist environment will maintain the cooling temperate and proper exchange of atmosphere around the wound. In the present study, the multifunctional graphene with silver and ε-Poly-l-lysine reinforced into the chitosan matrix (CGAPL) was prepared as a nanobiocomposite wound dressing...

Comorbid mental disorders in subjects at clinical high risk for psychosis (CHR-P) may impact preventive care. We conducted a PRISMA/MOOSE-compliant systematic meta-analysis, searching PubMed/PsycInfo up to June 21st, 2021 for observational studies/randomized controlled trials reporting on comorbid DSM/ICD-mental disorders in CHR-P subjects ( protocol ). The primary and secondary outcomes were baseline and follow-up prevalence of comorbid mental disorders. We also explored the association of comorbid mental disorders compared with CHR-P versus psychotic/non-psychotic control groups, their impact on baseline functioning and transition to psychosis...

BACKGROUND: Trauma patients are at high risk of Venous thromboembolism (VTE), but compared to well-established deep venous thrombosis (DVT), data specifically evaluating post-traumatic pulmonary embolism (PE) are scarce. The aim of this study is to assess whether PE represents a distinct clinical entity with injury pattern, risk factors, and prophylaxis strategy different from DVT, among severe poly-trauma patients. PATIENTS AND METHODS: We retrospectively enrolled patients admitted to our level I trauma center from January 2011 to December 2021 who were diagnosed with severe multiple traumatic injuries and identified thromboembolic events among them...

Silicone and e-poly(tetrafluoroethylene) (e-PTFE) are the most commonly used artificial materials for repairing maxillofacial bone defects caused by facial trauma and tumors. However, their use is limited by poor histocompatibility, unsatisfactory support, and high infection rates. Polyetheretherketone (PEEK) has excellent mechanical strength and biocompatibility, but its application to the repair of maxillofacial bone defects lacks a theoretical basis. The microstructure and mechanical properties of e-PTFE, silicone, and PEEK were evaluated by electron microscopy, BOSE machine, and Fourier transformed infrared spectroscopy...

Orthopedic trauma is one of the commonest injuries necessitating surgical intervention in a trauma patient. The management protocols in such severely injured orthopedic patients have evolved from conservative treatment to 'early total care' (ETC) to 'damage control orthopedics' (DCO) and recently to 'early appropriate care' (EAC)/'safe definitive surgery' (SDS). 'DCO' involves emergent, basic minimum life- or limb-saving surgery with continued resuscitation and definitive fixation of fractures being done later, once the patient has been resuscitated and stabilized...

Abdominal wall defect caused by surgical trauma, congenital rupture, or tumor resection may result in hernia formation or even death. Tension-free abdominal wall defect repair by using patches is the gold standard to solve such problems. However, adhesions following patch implantation remain one of the most challenging issues in surgical practice. The development of new kinds of barriers is key to addressing peritoneal adhesions and repairing abdominal wall defects. It's already well recognized that ideal barrier materials need to have good resistance to nonspecific protein adsorption, cell adhesion, and bacterial colonization for preventing the initial development of adhesion...
