Jin Y, Huang K, Shao T. [ 18F]Fluorodeoxyglucose ([ 18F]FDG) positron emission tomography and conventional imaging modalities in the diagnosis of diabetic foot osteomyelitis: a meta-analysis. Clin Radiol 2024:S0009-9260(24)00281-2. [PMID: 38880677 DOI: 10.1016/j.crad.2024.05.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/21/2024] [Accepted: 05/22/2024] [Indexed: 06/18/2024]
Abstract
AIM This meta-analysis aimed to evaluate the comparative diagnostic efficacy of [18F]Fluorodeoxyglucose positron emission tomography ([18F]FDG PET) and conventional imaging, MRI, and white blood cell (WBC) scintigraphy in detecting foot osteomyelitis among diabetic patients. MATERIALS AND METHODS An exhaustive search was conducted within the PubMed and Embase databases to identify publications available up until February 2024. Studies were included if they evaluated the diagnostic efficacy of [18F]FDG PET or the comparative diagnostic performance between PET and (MRI or WBC scintigraphy). Two researchers independently assessed the quality of the included studies, utilizing the Quality Assessment of Diagnostic Performance Studies (QUADAS-2) tool. RESULTS Nine retrospective or prospective studies involving 605 patients were included in the meta-analysis. For [18F]FDG PET, the overall sensitivity was 0.83(95% CI: 0.69-0.94), while the overall specificity was 0.92(95% CI: 0.86-0.97). In the head-to-head comparison, no significant difference of sensitivity was found between [18F]FDG PET and MRI (0.72 vs. 0.68, P=0.81), as well as between [18F]FDG PET and WBC scintigraphy (0.57 vs. 0.66, P=0.64). In addition, specificity was also found to be no significant difference between [18F]FDG PET and MRI (0.90 vs. 0.82, P=0.27), as well as [18F]FDG PET and WBC scintigraphy (0.81 vs. 0.93, P=0.09). CONCLUSION [18F]FDG PET demonstrates similar sensitivity and specificity to MRI and WBC scintigraphy in detecting foot osteomyelitis among diabetic patients. MRI, often cited as a primary choice in guidelines, might be preferred due to its lower cost and lower dose. Further larger sample prospective studies are needed to confirm these findings.

Abstract
BACKGROUND/AIM Probing brain tumor microvasculature holds significant importance in both basic cancer research and medical practice for tracking tumor development and assessing treatment outcomes. However, few imaging methods commonly used in clinics can noninvasively monitor the brain microvascular network at high precision and without exogenous contrast agents in vivo. The present study aimed to investigate the characteristics of microvasculature during brain tumor development in an orthotopic glioma mouse model. MATERIALS AND METHODS An orthotopic glioma mouse model was established by surgical orthotopic implantation of U87-MG-luc cells into the mouse brain. Then, optical coherence tomography angiography (OCTA) was utilized to characterize the microvasculature progression within 14 days. RESULTS The orthotopic glioma mouse model evaluated by bioluminescence imaging and MRI was successfully generated. As the tumor grew, the microvessels within the tumor area slowly decreased, progressing from the center to the periphery for 14 days. CONCLUSION This study highlights the potential of OCTA as a useful tool to noninvasively visualize the brain microvascular network at high precision and without any exogenous contrast agents in vivo.

Abstract
The study of ocular manifestations of neurodegenerative disorders, Oculomics, is a growing field of investigation for early diagnostics, enabling structural and chemical biomarkers to be monitored overtime to predict prognosis. Traumatic brain injury (TBI) triggers a cascade of events harmful to the brain, which can lead to neurodegeneration. TBI, termed the "silent epidemic" is becoming a leading cause of death and disability worldwide. There is currently no effective diagnostic tool for TBI, and yet, early-intervention is known to considerably shorten hospital stays, improve outcomes, fasten neurological recovery and lower mortality rates, highlighting the unmet need for techniques capable of rapid and accurate point-of-care diagnostics, implemented in the earliest stages. This review focuses on the latest advances in the main neuropathophysiological responses and the achievements and shortfalls of TBI diagnostic methods. Validated and emerging TBI-indicative biomarkers are outlined and linked to ocular neuro-disorders. Methods detecting structural and chemical ocular responses to TBI are categorised along with prospective chemical and physical sensing techniques. Particular attention is drawn to the potential of Raman spectroscopy as a non-invasive sensing of neurological molecular signatures in the ocular projections of the brain, laying the platform for the first tangible path towards alternative point-of-care diagnostic technologies for TBI.

Labelfree mapping and profiling of altered lipid homeostasis in the rat hippocampus after traumatic stress: Role of oxidative homeostasis. Neurobiol Stress 2022; 20:100476.

Abstract
Oxidative and lipid homeostasis are altered by stress and trauma and post-traumatic stress disorder (PTSD) is associated with alterations to lipid species in plasma. Stress-induced alterations to lipid oxidative and homeostasis may exacerbate PTSD pathology, but few preclinical investigations of stress-induced lipidomic changes in the brain exist. Currently available techniques for the quantification of lipid species in biological samples require tissue extraction and are limited in their ability to retrieve spatial information. Raman imaging can overcome this limitation through the quantification of lipid species in situ in minimally processed tissue slices. Here, we utilized a predator exposure and psychosocial stress (PE/PSS) model of traumatic stress to standardize Raman imaging of lipid species in the hippocampus using LC-MS based lipidomics and these data were confirmed with qRT-PCR measures of mRNA expression of relevant enzymes and transporters. Electron Paramagnetic Resonance Spectroscopy (EPR) was used to measure free radical production and an MDA assay to measure oxidized polyunsaturated fatty acids. We observed that PE/PSS is associated with increased cholesterol, altered lipid concentrations, increased free radical production and reduced oxidized polyunsaturated fats (PUFAs) in the hippocampus (HPC), indicating shifts in lipid and oxidative homeostasis in the HPC after traumatic stress.

Super-resolution generative adversarial networks with static T2*WI-based subject-specific learning to improve spatial difference sensitivity in fMRI activation. Sci Rep 2022; 12:10319.

Abstract
The spatial resolution of fMRI is relatively poor and improvements are needed to indicate more specific locations for functional activities. Here, we propose a novel scheme, called Static T2*WI-based Subject-Specific Super Resolution fMRI (STSS-SRfMRI), to enhance the functional resolution, or ability to discriminate spatially adjacent but functionally different responses, of fMRI. The scheme is based on super-resolution generative adversarial networks (SRGAN) that utilize a T2*-weighted image (T2*WI) dataset as a training reference. The efficacy of the scheme was evaluated through comparison with the activation maps obtained from the raw unpreprocessed functional data (raw fMRI). MRI images were acquired from 30 healthy volunteers using a 3 Tesla scanner. The modified SRGAN reconstructs a high-resolution image series from the original low-resolution fMRI data. For quantitative comparison, several metrics were calculated for both the STSS-SRfMRI and the raw fMRI activation maps. The ability to distinguish between two different finger-tapping tasks was significantly higher [p = 0.00466] for the reconstructed STSS-SRfMRI images than for the raw fMRI images. The results indicate that the functional resolution of the STSS-SRfMRI scheme is superior, which suggests that the scheme is a potential solution to realizing higher functional resolution in fMRI images obtained using 3T MRI.

Abstract
Post-traumatic stress disorder (PTSD) is associated with cognitive deficits, oxidative stress, and inflammation. Animal models have recapitulated features of PTSD, but no comparative RNA sequencing analysis of differentially expressed genes (DEGs) in the brain between PTSD and animal models of traumatic stress has been carried out. We compared DEGs from the prefrontal cortex (PFC) of an established stress model to DEGs from the dorsolateral PFC (dlPFC) of humans. We observed a significant enrichment of rat DEGs in human PTSD and identified 20 overlapping DEGs, of which 17 (85%) are directionally concordant. N,N-dimethyltryptamine (DMT) is a known indirect antioxidant, anti-inflammatory, and neuroprotective compound with antidepressant and plasticity-facilitating effects. We tested the capacity of DMT, the monoamine oxidase inhibitor (MAOI) harmaline, and "pharmahuasca" (DMT + harmaline) to reduce reactive oxygen species (ROS) production and inflammatory gene expression and to modulate neuroplasticity-related gene expression in the model. We administered DMT (2 mg/kg IP), harmaline (1.5 mg/kg IP), pharmahuasca, or vehicle every other day for 5 days, following a 30 day stress regiment. We measured ROS production in the PFC and hippocampus (HC) by electron paramagnetic resonance spectroscopy and sequenced total mRNA in the PFC. We also performed in vitro assays to measure the affinity and efficacy of DMT and harmaline at 5HT2AR compared to 5-HT. DMT and pharmahuasca reduced ROS production in the PFC and HC, while harmaline had mixed effects. Treatments normalized 9, 12, and 14 overlapping DEGs, and pathway analysis implicated that genes were involved in ROS production, inflammation, growth factor signaling, neurotransmission, and neuroplasticity.

Abstract
UNLABELLED Background: Posttraumatic stress symptoms (PTSS) include a constellation of physical and emotional profiles that youth exposed to trauma may experience. An estimated 20% of youth are exposed to trauma, and in refugee populations, up to 54% experience posttraumatic stress. Given the physical and mental health consequences associated with trauma exposure and subsequent psychopathology, identifying biomarkers of symptom severity is a top research priority. Objective: Previous research in adults found that skin conductance responses to trauma interview predicted current and future PTSS. We extended this method to refugee youth exposed to civilian war trauma and forced migration, to examine associations between PTSS and skin conductance in this uniquely vulnerable child and adolescent population. Methods: 86 refugee youth ages 7-17 years completed a trauma interview and assessment of self-reported PTSS. The mobile eSense app on a iPad was used to obtain continuous recordings of skin conductance level (SCL) during a trauma interview (trauma SCL). Skin conductance response (SCR) was calculated by subtracting the baseline SCL from the maximum amplitude of the trauma SCL. Results: SCL during trauma was significantly greater than baseline SCL, Trauma exposure was significantly associated with SCR to trauma interview, R2 = .084, p = .042. SCR to trauma interview was positively correlated with reexperiencing (R2 = .127, p = .028), and hyperarousal symptoms (R 2 = .123, p = .048). Conclusions: The present study provides evidence for feasibility of SCR to trauma interview as a candidate biomarker of PTSS in youth. This is the first study to look at SCR to trauma interview in youth resettled as refugees and is part of the limited but growing body of research to look at biomarkers in refugee cohorts more broadly. As the number of forcibly displaced persons surges, early detection and prevention of trauma-related psychology is becoming more important than ever. HIGHLIGHTS Using the mobile eSense app, we demonstrate that skin conductance is measurable in a variety of research settings and that skin conductance response may be a biological indicator of trauma and related psychopathology - namely re-experiencing symptoms - in youth resettled as refugees.

Abstract
BACKGROUND Alterations in white matter microstructure associated with chronic alcohol use have been demonstrated in previous diffusion tensor imaging (DTI) research. However, there is conflicting evidence as to whether such differences are influenced by an individual's biological sex. The purpose of the present study was to investigate the prevalence of sex differences in the white matter microstructure of the brains of individuals with alcohol use disorder (AUD) and healthy controls. METHODS One hundred participants with AUD (38 female, aged 21 to 68) participating in the National Institute on Alcohol Abuse and Alcoholism's inpatient treatment program and 98 healthy control participants (52 female) underwent a diffusion-weighted scan. Images collected were processed for each subject individually, and voxelwise, tract-based spatial statistics analysis was conducted to test for differences in the DTI measures of fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD). RESULTS A 2-way, between-subjects ANCOVA that tested for differences by group and sex revealed widespread differences between AUD and control subjects, but no interaction between group and sex. Additional analyses exploring demographic and alcohol use variables showed significant impacts of age on white matter microstructure that were more pronounced in individuals with AUD. Plots of FA by age, sex, and group in major white matter tracts suggest a need to explore higher order interactions in larger samples. CONCLUSIONS These results bolster recent findings of similar microstructural properties in men and women with AUD but provide a rationale for the consideration of age when investigating the impacts of chronic alcohol use on the brain's white matter.

Abstract
Background Coronavirus has affected more than 100 million people. Most of these patients are hospitalized in isolation wards or self-quarantined at home. A significant percentage of COVID-19 patients may experience psychiatric symptoms. This study attempts to assess depressive, anxiety, and post-traumatic stress symptoms in home-isolated and hospitalized COVID-19 patients, besides whether the isolation setting affected these symptoms’ presentation. Results The study involved 89 patients with confirmed COVID-19 virus, and the patients were divided into 2 groups: 43 patients in the home-isolated group (group A) and 46 patients in the hospital-isolated group (group B). The majority of subjects were male and married; also, they were highly educated. 30.2% from group A and 47.8% from group B had a medical occupation. There was a statistically significant difference (p= 0.03) between both groups in the presence of chronic disease. There was a statistically significant increase in suicidal thoughts in the home-isolated group (37.2%) (p = 0.008**). We found a statistically significant increase in the abnormal scores of Hospital Anxiety Depression Scale–Depression (HADS–Depression) in the home-isolated group (69.7%) compared to the hospital-isolated group (32.6%) (p <0.001**) which denotes considerable symptoms of depression. Moreover, we found that (32.6%) from the home-isolated group and (39.1%) from the hospital-isolated group had abnormal scores of Hospital Anxiety Depression Scale–Anxiety (HADS–Anxiety) which denotes considerable symptoms of anxiety. Also, we found 66.7% and 87.2% scored positive by the Davidson Trauma Scale (DTS) in the home-isolated group and hospital-isolated group, respectively. Which was statistically significant (p = 0.02**). On doing a binary logistic regression analysis of HADS and DTS with significantly related independent factors, we revealed that lower education levels and family history of psychiatric disorder were risk factors for abnormal HADS–Anxiety scores in COVID-19 patients. The medical occupation was a protective factor against having abnormal HADS–Depression scores in COVID-19 patients, while home isolation was a risk factor. On the contrary, the medical occupation was a risk factor for scoring positive in DTS in COVID-19 patients. Simultaneously, low levels of education and home isolation were protective factors. Conclusion A significant number of patients diagnosed with the COVID-19 virus develop depressive, anxiety, and post-traumatic stress symptoms, whether they were isolated in the hospital or at home; besides, the isolation setting may affect the presenting symptoms.

Abstract
The past few decades have seen an explosion in the development and use of methods for imaging the human microcirculation during health and disease. The confluence of innovative imaging technologies, affordable computing power, and economies of scale have ushered in a new era of "translational" imaging that permit us to peer into blood vessels of various organs in the human body. These imaging techniques include near-infrared spectroscopy (NIRS), positron emission tomography (PET), and magnetic resonance imaging (MRI) that are sensitive to microvascular-derived signals, as well as computed tomography (CT), optical imaging, and ultrasound (US) imaging that are capable of directly acquiring images at, or close to microvascular spatial resolution. Collectively, these imaging modalities enable us to characterize the morphological and functional changes in a tissue's microcirculation that are known to accompany the initiation and progression of numerous pathologies. Although there have been significant advances for imaging the microcirculation in preclinical models, this review focuses on developments in the assessment of the microcirculation in patients with optical imaging, NIRS, PET, US, MRI, and CT, to name a few. The goal of this review is to serve as a springboard for exploring the burgeoning role of translational imaging technologies for interrogating the structural and functional status of the microcirculation in humans, and highlight the breadth of current clinical applications. Making the human microcirculation "visible" in vivo to clinicians and researchers alike will facilitate bench-to-bedside discoveries and enhance the diagnosis and management of disease.

Effects of aluminum chloride and coenzyme Q10 on the molecular structure of lipids and the morphology of the brain hippocampus cells. RSC Adv 2021; 11:29925-29933. [PMID: 35480272 PMCID: PMC9040883 DOI: 10.1039/d1ra03786b] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 11/08/2021] [Accepted: 09/01/2021] [Indexed: 12/12/2022] Open
Abstract
Aluminum chloride (AlCl3) is a neurotoxic substance, while coenzyme Q10 (CoQ10) is considered a lipid antioxidant. Herein, their effects on the molecular structure of lipids and the morphology of the hippocampus brain tissue were investigated. Three groups of Wistar albino male rats were used in this study. For four weeks, one group was kept as a control group; the second group was given AlCl3; the third group was given AlCl3/CoQ10. Fourier transform infrared (FTIR) and histopathological examinations were utilized to estimate alterations in the molecular structure of the lipids and the cell morphology, respectively. The FTIR spectra revealed considerable decreases in the CH contents and alterations in the molecular ratios of olefinic

CH/νas(CH3), νas(CH2)/νas(CH3), and νas(CH2)/[νas(CH2) + νs(CH2)] in the group given AlCl3. However, no significant changes were detected in those rats given AlCl3/CoQ10. Histopathology images uncovered shrinking and dark centers in the pyramidal cells of brain tissue hippocampal cells. The diameters of the pyramidal cells were estimated to be 4.81 ± 0.55 μm, 4.04 ± 0.71 μm, and 4.63 ± 0.71 μm for the control, AlCl3, and AlCl3/CoQ10 groups, respectively. The study showed that the AlCl3 could cause a shrinking of around 16% in the hippocampus pyramidal cells; besides, CoQ10 is a powerful therapeutic antioxidant to help restore the hippocampal neurons to a regular state. Although the AlCl3 affected the molecular structure of lipids and the morphology of the brain hippocampus cells, the CoQ10 showed a powerful therapeutic antioxidant being helped restore the hippocampal neurons to their normal state.![]()

Abstract
As a severe and highly contagious infectious disease, coronavirus disease 2019 (COVID-19) has caused a global pandemic. Several case reports have demonstrated that the respiratory system is the main target in patients with COVID-19, but the disease is not limited to the respiratory system. Case analysis indicated that the nervous system can be invaded by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that 36.4% of COVID-19 patients had neurological symptoms. Importantly, the involvement of the CNS may be associated with poor prognosis and disease worsening. Here, we discussed the symptoms and evidence of nervous system involvement (directly and indirectly) caused by SARS-CoV-2 infection and possible mechanisms. CNS symptoms could be a potential indicator of poor prognosis; therefore, the prevention and treatment of CNS symptoms are also crucial for the recovery of COVID-19 patients.
