Exploring cerebral structural and functional abnormalities in a mouse model of post-traumatic headache induced by mild traumatic brain injury

Mild traumatic brain injury(mTBI)-induced post-traumatic headache(PTH)is a pressing public health concern and leading cause of disability worldwide.Although PTH is often accompanied by neurological disorders,the exact underlying mechanism remains largely unknown.Identifying potential biomarkers may prompt the diagnosis and development of effective treatments for mTBI-induced PTH.In this study,a mouse model of mTBI-induced PTH was established to investigate its effects on cerebral structure and function during short-term recovery.Results indicated that mice with mTBI-induced PTH exhibited balance deficits during the early post-injury stage.Metabolic kinetics revealed that variations in neurotransmitters were most prominent in the cerebellum,temporal lobe/cortex,and hippocampal regions during the early stages of PTH.Additionally,variations in brain functional activities and connectivity were further detected in the early stage of PTH,particularly in the cerebellum and temporal cortex,suggesting that these regions play central roles in the mechanism underlying PTH.Moreover,our results suggested that GABA and glutamate may serve as potential diagnostic or prognostic biomarkers for PTH.Future studies should explore the specific neural circuits involved in the regulation of PTH by the cerebellum and temporal cortex,with these two regions potentially utilized as targets for non-invasive stimulation in future clinical treatment.

Ginger oil-loaded transdermal adhesive patch treats post-traumatic stress disorder

Objective To find a viable alternative to reduce the number of doses required for the patients with post-traumatic stress disorder(PTSD),and to improve efficacy and patient compliance.Methods In this study,we used ginger oil,a phytochemical with potential therapeutic properties,to prepare ginger oil patches.High-performance liquid chromatography(HPLC)was used to quantify the main active component of ginger oil,6-gingerol.Transdermal absorption experiments were conducted to optimize the various pressure-sensitive adhesives and permeation enhancers,including their type and concentration.Subsequently,the ginger oil patches were optimized and subjected to content determination and property evaluations.A PTSD mouse model was established using the foot-shock method.The therapeutic effect of ginger oil patches on PTSD was assessed through pathological sections,behavioral tests,and the evaluation of biomarkers such as tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),brain-derived neurotrophic factor(BDNF),and melatonin(MT).Results The results demonstrated that ginger oil patches exerted therapeutic effects against PTSD by inhibiting inflammatory responses and modulating MT and BDNF levels.Pharmacokinetic experiments revealed that ginger oil patches maintained a stable blood drug concentration for at least one day,addressing the rapid metabolism drawback of 6-gingerol and enhancing its therapeutic efficacy.Conclusions Ginger oil can be prepared as a transdermal drug patch that meets these requirements,and the bioavailability of the prepared patch is better than that of oral administration.It can improve PTSD with good patient compliance and ease of administration.Therefore,it is a promising therapeutic formulation for the treatment of PTSD.

Addressing trauma,post-traumatic stress disorder,and posttraumatic growth in breast cancer patients

BACKGROUND Breast cancer(BC)is a common cancer among females in Africa.Being infected with BC in Africa seems like a life sentence and brings devastating experiences to patients and households.As a result,BC is comorbid with trauma,post-traumatic stress disorder(PTSD),and post-traumatic growth(PTG).AIM To identify empirical evidence from peer-reviewed articles on the comorbidity trajectories between BC and trauma,BC and PTSD,and BC and PTG.METHODS This review adhered to the PRISMA guidelines of conducting a systematic review.Literature searches of the National Library of Medicine,Scopus,PubMed,Google Scholar,and Scopus databases were conducted using search terms developed for the study.The search hint yielded 769 results,which were screened based on inclusion and exclusion criteria.At the end of the screening,24 articles were included in the systematic review.RESULTS BC patients suffered trauma and PTSD during the diagnosis and treatment stages.These traumatic events include painful experiences during and after diagnosis,psychological distress,depression,and cultural stigma against BC patients.PTSD occurrence among BC patients varies across African countries,as this review disclosed:90%was reported in Kenya,80%was reported in Zimbabwe,and 46%was reported in Nigeria.The severity of PTSD among BC patients in Africa was based on the test results communicated to the patients.Furthermore,this review revealed that BC patients experience PTG,which involves losing,regaining,and surrendering final control over the body,rebuilding a personified identity,and newfound appreciation for the body.CONCLUSION Patients with BC undergo numerous traumatic experiences during their diagnosis and treatment.Psychological interventions are needed in SSA to mitigate trauma and PTSD,as well as promote PTG.

MicroRNAs as potential biomarkers for diagnosis of post-traumatic stress disorder

Post-traumatic stress disorder is a mental disorder caused by exposure to severe traumatic life events.Currently,there are no validated biomarkers or laboratory tests that can distinguish between trauma survivors with and without post-traumatic stress disorder.In addition,the heterogeneity of clinical presentations of post-traumatic stress disorder and the overlap of symptoms with other conditions can lead to misdiagnosis and inappropriate treatment.Evidence suggests that this condition is a multisystem disorder that affects many biological systems,raising the possibility that peripheral markers of disease may be used to diagnose post-traumatic stress disorder.We performed a PubMed search for microRNAs(miRNAs)in post-traumatic stress disorder(PTSD)that could serve as diagnostic biomarkers and found 18 original research articles on studies performed with human patients and published January 2012 to December 2023.These included four studies with whole blood,seven with peripheral blood mononuclear cells,four with plasma extracellular vesicles/exosomes,and one with serum exosomes.One of these studies had also used whole plasma.Two studies were excluded as they did not involve microRNA biomarkers.Most of the studies had collected samples from adult male Veterans who had returned from deployment and been exposed to combat,and only two were from recently traumatized adult subjects.In measuring miRNA expression levels,many of the studies had used microarray miRNA analysis,miRNA Seq analysis,or NanoString panels.Only six studies had used real time polymerase chain reaction assay to determine/validate miRNA expression in PTSD subjects compared to controls.The miRNAs that were found/validated in these studies may be considered as potential candidate biomarkers for PTSD and include miR-3130-5p in whole blood;miR-193a-5p,-7113-5p,-125a,-181c,and-671-5p in peripheral blood mononuclear cells;miR-10b-5p,-203a-3p,-4488,-502-3p,-874-3p,-5100,and-7641 in plasma extracellular vesicles/exosomes;and miR-18a-3p and-7-1-5p in blood plasma.Several important limitations identified in the studies need to be taken into account in future studies.Further studies are warranted with war veterans and recently traumatized children,adolescents,and adults having PTSD and use of animal models subjected to various stressors and the effects of suppressing or overexpressing specific microRNAs.

Post-Traumatic Stress Disorder among Defence and Security Forces in Northern Benin (2023)

Introduction: Post-traumatic stress disorder (PTSD) is defined as “actual exposure to death or the threat of death, serious injury or sexual violence”, either directly or indirectly, resulting in a symptomatic procession of repetition, avoidance, neurovegetative hyperactivity and individualized symptoms, with or without negative cognitive and mood changes. It therefore goes without saying that the defence and security forces constitute a high-risk population in need of attention. Objective: To study post-traumatic stress disorder in defence and security forces in the city of Parakou in 2023. Methods: Descriptive cross-sectional study conducted from December 2022 to July 2023. The study population consisted of active military, republican police and firefighters in the city of Parakou in 2023. Non-proportional stratified sampling was used, given the inaccessibility of the source population size for national security reasons. Post-traumatic stress disorder was assessed using the “post-traumatic stress disorder checklist-5 (PCLS-5) scale. Results: A total of 305 subjects participated in the survey. Males dominated 90.2%. The most represented corps was the Republican Police (41.6%), most of whom were non-commissioned officers (46.6%). The majority count between 11 and 20 years of service (48.9%), with 2 to 5 missions completed (67.5%). The calculated prevalence of post-traumatic stress disorder was 11.8%, based on the post-traumatic stress disorder checklist-5 (PCL-5). Of the 36 respondents with post-traumatic stress disorder, 20 (55.6%) had experienced an armed attack, 25 (69.4%) had witnessed a violent death, 18 (50.0%) had witnessed the agony of a colleague, 15 (41.7%) had been exposed to a fire or explosion, while 26 (72.2%) had been traumatized by physical and/or verbal aggression. 5 (13.9%) had consulted a specialist psychiatrist, while 6 (16.7%) were on medication and 26 (72.2%) used sport as a means of maintaining physical and mental health. Respectively 22 (61.1%) and 21 (58.3%) had definite symptoms of anxiety and depression. Multivariate analysis revealed a significant association between post-traumatic stress disorder and the following variables: total number of children ≤ 2 (p = 0.015), comorbidities such as arterial hypertension (p = 0.007), history of hepatitis (p = 0.017), work accidents (p = 0.016), alcohol dependence (p = 0.004), domestic violence (p = 0.004), psychological violence (p = 0.017) and anxiety disorders (p Conclusion: Defence and security personnel can also be prey to post-traumatic stress disorder (PTSD), which needs to be systematically taken into account when they are subjected to trauma in the course of their duties. Mental health should be an integral part of the periodic medical check-up objectives for defence and security forces throughout the country.

Principles and Techniques of Post-Traumatic Rhinoplasty: A Review of the Literature

Post-traumatic rhinoplasty is the surgical treatment of the complex functional and aesthetic sequelae of nasal trauma. Correcting a post-traumatic nose is a challenging task, requiring the surgeon to employ a range of techniques and grafts to adequately address the deformities observed. The results of our research show that restoring pre-traumatic form and function remains complex, although many guidelines have been established to refine and optimize the management of the after-effects of nasal trauma. But it is achievable with the right techniques. The objective of our review is to highlight the various post-traumatic nasal sequelae, describe the fundamental principles in the field of post-traumatic rhinoplasty and provide the surgeon with the various existing surgical techniques and strategies so that he or she can make an appropriate choice for the patient.

Post-traumatic heterotopic ossification in front of the ankle joint for 23 years:A case report and review of literature

BACKGROUND Heterotopic ossification(HO)refers to the formation of new bone in non-skeletal tissues such as muscles,tendons or other soft tissues.Severe muscle and soft tissue injury often lead to the formation of HO.However,anterior HO of the ankle is rarely reported.CASE SUMMARY We report a patient with massive HO in front of the ankle joint for 23 years.In 1998,the patient was injured by a falling object on the right lower extremity,which gradually formed a massive heterotopic bone change in the right calf and dorsum of the foot.The patient did not develop gradual ankle function limitations until nearly 36 mo ago,and underwent resection of HO.Even after 23 years and resection of HO,the ankle joint was still able to move.CONCLUSION It is recommended that the orthopedist should be aware of HO and distinguish it from bone tumor.

Post-traumatic cauda equina nerve calcification:A case report

BACKGROUND Post-traumatic cauda equina nerve calcification is extremely rare in clinical practice,and its etiology,pathogenesis,treatment and prognosis are unclear.There are few studies and reports on Post-traumatic cauda equina nerve calci-fication,and this review reports a case of Post-traumatic cauda equina nerve calcification for reference.CASE SUMMARY A 52-year-old patient presented to our hospital with a history of lumbar spinal stenosis and a lumbar vertebral fracture caused by trauma.The patient's right lower limb had weakness in hip flexion,knee extension and plantarflexion with muscle strength grade 3,right ankle dorsiflexion and thumb dorsiflexion with muscle strength grade 0.The patient's skin sensation below the right knee plane disappeared.The patient's Computed tomography(CT)data showed signs of cauda equina nerve calcification and the terminal filaments in the plane of the third to fifth lumbar vertebrae.After treatment the patient's symptoms were slightly relieved.CONCLUSION We provide an extremely rare case of Post-traumatic cauda equina nerve calcification and offer a conservative treatment plan.However,the etiology,mechanism and treatment of Post-traumatic cauda equina nerve calcification are still unclear.This requires scholars to conduct more research and exploration in this area.

Relationship between perceived social support and post-traumatic growth in coronavirus disease 2019 patients discharged from the hospital

BACKGROUND The coronavirus disease 2019(COVID-19)pandemic has affected mental health and physical health negatively in some individuals.Examining perceived social support and post-traumatic growth(PTG)in COVID-19 patients could facilitate our understanding of how patients maintain their mental health.AIM To examine the relationship between the level of perceived social support and PTG in COVID-19 patients discharged from the hospital.METHODS This descriptive study was carried out between August and September 2022 with patients who were hospitalized due to COVID-19 in a university hospital in Erzurum and who were discharged at least 3 mo prior to the beginning of the study.The study was completed by 196 patients.Study data were collected faceto-face using a personal information form,multidimensional scale of perceived social support and PTG inventory.RESULTS The total mean score of the multidimensional scale of perceived social support was 63.82±15.72.The PTG inventory total mean score was 47.77±19.85.In addition,a direct significant correlation was found between perceived social support in COVID-19 patients and PTG.CONCLUSION The study results showed that perceived social support variables affected PTG significantly.Therefore,it is recommended for healthcare professionals to implement interventions to promote social support from healthcare professionals and the patient’s family and friends.Considering the negative effects of the ongoing COVID-19 pandemic,it is very important and necessary to implement effective public health interventions to promote PTG to reduce mental health problems.

Effectiveness of Post-Traumatic Growth Intervention to Promote Positive Post-Traumatic Traits in Chinese Breast Cancer Patients:A Randomized Controlled Trial

Objective:The purpose of this study was to evaluate the effectiveness of post-traumatic growth(PTG)model-based intervention to improve positive psychological traits in Chinese breast cancer patients.Design:A randomized control trial of a psychological group intervention based on PTG model.Methods:The Clinical Trial was registered on 17 August 2019 at Chinese Clinical Trials.gov with Registration number ChiCTR1900025264.A total of 92 patients with breast cancer were recruited.The participants were randomly assigned to the experimental group(n=46)and the control group(n=46).A six-session psychological group intervention based on PTG model was implemented in the experimental group,and a six-session health education was implemented in the control group.The outcomes weremeasured at baseline(pre-intervention),3 weeks,6 weeks after the intervention.The primary outcome was posttraumatic growth assessed by the Chinese version of the Post-Traumatic Growth Inventory(PTGI);Secondary outcomes included psychological resilience,family resilience,rumination,and self-disclosure.Results:A total of 87 patients with breast cancer completed this study,including 44 patients in the experimental group and 43 patients in the control group.There was no significant difference in baseline data of breast cancer patients between the two groups except for the treatment regimen(p>0.05).The two groups were compared after the intervention;the interaction effects between the total scores of posttraumatic growth,family resilience,and self-disclosure and the time term were statistically significant(p<0.05),indicating that the trend of change in total scores of post-traumatic growth,family resilience,and self-disclosure differed between the experimental and control groups over time,and the scores improved in the experimental group were significantly higher than those in the control group.The comparison of psychological resilience and total score of rumination at each time point was statistically significant(p<0.05),indicating that group intervention based on the PTG model could improve the psychological recovery ability and rumination level of the experimental group.Conclusion:The psychological group intervention based on the PTG model significantly improved post-traumatic growth,family resilience,and self-disclosure in patients with breast cancer.However,the impact on psychological resilience and rumination was relatively small.Long-term intervention is needed to further test the effect of the PTG model on psychological resilience and rumination.

Risk factors for post-traumatic stress disorder among young and middle-aged cancer patients in the intensive care unit:A casecontrol study

BACKGROUND Young and middle-aged cancer patients in intensive care unit(ICU)often suffer from stress and pressure,causing huge physical and mental damage.Currently,there is few research on post-traumatic stress disorder(PTSD)among young and middle-aged cancer patients in ICU in China,and the psychological status of patients who have experienced both cancer development and ICU stay is still unclear.AIM To explore the risk factors for PTSD in young and middle-aged patients with cancer in ICU.METHODS Using convenient sampling method,we enrolled 150 young and middle-aged patients with cancer who were admitted to the ICU of our center during the period from July to December 2020.The general data of the patients and PTSDrelated indicators were collected.The Impact of Event Scale-Revised(IES-R)was used for assessing PTSD one month after the discharge from the ICU.Binary Logistic regression analysis was performed to assess the independent risk factors for PTSD in these patients.RESULTS Among these 150 patients,32(21.33%)were found to be with PTSD.Binary Logistic regression analysis revealed that factors significantly associated with PTSD among young and middle-aged patients with cancer in ICU included monthly income(OR=0.24,P=0.02),planned transfers(OR=0.208,P=0.019),and Acute Physiology and Chronic Health Evaluation(APACHE II)score(OR=1.171,P=0.003).CONCLUSION The low monthly income,unplanned transfers,and increased APACHE II score are the risk factors for PTSD in young and middle-aged patients with cancer in ICU.

Research progress on the biological effects of BDNF and proBDNFs in post-traumatic stress disorder

Many people were affected psycho-logically and even traumatized by the outbreak of new coronavirus pneumonia in 2020,which has the potential to lead to post-traumatic stress disorder.Many neuropsy-chiatric illnesses are aided by brain-derived neurotrophic factor and its predecessors.Brain-derived neurotrophic factor precursors have the biological impact of triggering neuronal apoptosis and hindering neural regeneration,and brain-derived neurotrophic factor itself can help increase the growth,survival,and differentiation of central and peripheral nerve cells.This article provides an in-depth study of their biological impacts in post-traumatic stress disorder in an attempt to understand the biological effects of brain-derived neurotrophic factor and its precursor proteins.

A Case Report on Sandplay Therapy for a 3-Year-11-Month-Old Child with Post-Traumatic Stress Disorder

This report presents a case study of sandplay therapy for a 3-year-11-month-old child with post-traumatic stress disorder. The child had experienced a distressing traumatic event and exhibited symptoms of anxiety, fear, and traumatic reenactment. Sandplay therapy, as a therapeutic modality, was utilized to provide a safe environment for the child to express and process their inner experiences. The case report provides a detailed account of the child’s presentation, treatment goals, therapeutic strategies, and treatment outcomes. Through sandplay therapy, the child achieved emotional release, resolution of internal conflicts, and a reframing of the traumatic event. Ultimately, a significant reduction in symptoms of post-traumatic stress disorder was observed, along with improved functioning and psychological well-being.

Post-traumatic stress disorder risk and brain-derived neurotrophic factor Val66Met

Brain-derived neurotrophic factor(BDNF), which regulates neuronal survival, growth differentiation, and synapse formation, is known to be associated with depression and post-traumatic stress disorder(PTSD). However, the molecular mechanism for those mental disorders remains unknown. Studies have shown that BDNF is associated with PTSD risk and exaggerated startle reaction(a major arousal manifestation of PTSD) in United States military service members who were deployed during the wars in Iraq and Afghanistan. The frequency of the Met/Met in BDNF gene was greater among those with PTSD than those without PTSD. Among individuals who experienced fewer lifetime stressful events, the Met carriers have significantly higher total and startle scores on the PTSD Checklist than the Val/Val carriers. In addition, subjects with PTSD showed higher levels of BDNF in their peripheral blood plasma than the non-probable-PTSD controls. Increased BDNF levels and startle response were observed in both blood plasma and brain hippocampus by inescapable tail shock in rats. In this paper, we reviewed these data to discuss BDNF as a potential biomarker for PTSD risk and its possible roles in the onset of PTSD.

Total knee arthroplasty for treatment of post-traumatic arthritis: Systematic review

AIM To review and report functional outcomes, complications,and survivorship associated with total knee arthroplasty(TKA) in the treatment of post-traumatic arthritis(PTA).METHODS We conducted a systematic review according to the PRISMA guidelines. We searched PubMed, Cochrane Library, and SCOPUS in December 2015 for Englishlanguage clinical research studies, both prospective and retrospective, examining the use of TKA for the treatment of PTA. All relevant articles were accessed in full. The manual search included references of retrieved articles.We extracted data on patients' demographics and clinical outcomes, including preoperative diagnosis and pre- and post-operative functional scores. We summarized the data and reported the results in tables and text.RESULTS Sixteen studies, four prospective and ten retrospective,examined patients who underwent TKA for PTA due to fractures of the proximal tibia, patella, and/or distal femur. Eleven studies utilized the Knee Society Scores criteria to assess functional outcomes. All studies utilizing these criteria reported an improvement in functional and knee scores of patients following TKA. Further, studies reported an increased range of motion(ROM) and reduction of pain following surgery. The most commonly reported complications with TKA included infection, stiffness, wound complications, intraoperative rupture of tendons, and osteolysis/polyethylene wear. The overwhelming majority of these complications occurred within the first two years following surgery. Six studies examined the survivorship of TKA with subsequent revision for any reason as an endpoint. Compared to patients with osteoarthritis, patients with PTA required more revisions, the majority for polyethylene wear.CONCLUSION Although associated with higher complication rates,TKA is an effective treatment for PTA, as it improves ROM, pain and functional outcomes.

Poor prognostic factors in post-traumatic endophthalmitis following open globe injury

AIM:To demonstrate prognostic factors for poor visual outcome in patients with post-traumatic endophthalmitis(PTE)following open globe injury.METHODS:A retrospective study was conducted on 66 patients(66 eyes)with PTE following open globe injury from 2005 to 2015.Potential factors accounting for good and poor visual outcome were statistically analyzed by Chisquare test and Logistic regression model.RESULTS:In 66 cases,39 cases(59%)had a poor visual outcome.Univariate and multivariate Logistic regression analysis identified retained intraocular foreign body(IOFB)as the only factor significantly associated with poor visual outcome[adjusted odds ratio,4.62;95%confidence interval(1.04-20.53);P=0.04].The most common causative agents were gram-positive organisms(83%),of which Bacillus cereus(33%),was the most common pathogen.All cases received intravitreal antibiotic injections.Oral ciprofloxacin was the most used systemic antibiotic(33%).Pars plana vitrectomy was performed in 83%(55/66)of cases.At 6 mo follow-up,mean BCVA was 1.74±0.72 log MAR units.CONCLUSION:In patients with PTE following open globe injury,the only predictor of poor visual outcome is the presence of IOFB.Bacillus cereus is the most isolated microorganism.

Elevated NKCC1 transporter expression facilitates early post-traumatic brain injury seizures
