A SWOT analysis of nano co-crystals in drug delivery: present outlook and future perspectives.
The formulation of poorly soluble drugs is an intractable challenge in the field of drug design, development and delivery. This is particularly problematic for molecules that exhibit poor solubility in both organic and aqueous media. Usually, this is difficult to resolve using conventional formulation strategies and has resulted in many potential drug candidates not progressing beyond early stage development. Furthermore, some drug candidates are abandoned due to toxicity or have an undesirable biopharmaceutical profile. In many instances drug candidates do not exhibit desirable processing characteristics to be manufactured at scale. Nanocrystals and co-crystals, are progressive approaches in crystal engineering that can solve some of these limitations. While these techniques are relatively facile, they also require optimisation. Combining crystallography with nanoscience can yield nano co-crystals that feature the benefits of both fields, resulting in additive or synergistic effects to drug discovery and development. Nano co-crystals as drug delivery systems can potentially improve drug bioavailability and reduce the side-effects and pill burden of many drug candidates that require chronic dosing as part of treatment regimens. In addition, nano co-crystals are carrier-free colloidal drug delivery systems with particle sizes ranging between 100 and 1000 prising a drug molecule, a co-former and a viable drug delivery strategy for poorly soluble drugs. They are simple to prepare and have broad applicability. In this article, the strengths, weaknesses, opportunities and threats to the use of nano co-crystals are reviewed and a concise incursion into the salient aspects of nano co-crystals is undertaken.

Preparation of STF-loaded micron scale polyurethane polyurea double layer microcapsules and study on the mechanical properties of composites.
In this study, we report on a novel and effective approach for the encapsulation of the shear thickening fluid in polyurethane polyurea double layer microcapsules. Under the action of dibutyltin disilicate as a catalyst, CD-MDI reacted with polyethylene glycol to form polyurethane inner shell and reacted with diethylenetriamine to form a polyurea outer shell. The results show that the shear thickening liquid was emulsified using liquid paraffin as a solvent and Span80 as a surfactant to form a lotion similar to water-in-oil. The shear thickened droplets can be stably and uniformly dispersed to a diameter of 100 μm at a rotation speed of 800 rpm min

'H-type' tracheoesophageal fistula in an infant: A case report.
Congenital isolated 'H-type' tracheoesophageal fistula (TOF) is a rare disorder which is difficult to diagnose. Clinical presentation is characterised by a triad consisting of paroxysmal coughing and cyanosis during feeds; recurrent chest infections and failure to thrive; and abdominal distention secondary to gaseous loading of the bowel. It is often difficult to diagnose 'H-type' TOF because the continuity of the oesophagus is not interrupted. The diagnosis is often missed or delayed, leading plications such as chronic lung disease and failure to thrive.

Regulatory challenges in conducting human subjects research in emergency settings: the National Trauma Research Action Plan (NTRAP) scoping review.
plexity of the care environment, the emergent nature, and the severity of patient injury make conducting clinical trauma research challenging. These challenges hamper the ability to investigate potentially life-saving research that aims to deliver pharmacotherapeutics, test medical devices, and develop technologies that may improve patient survival and recovery. Regulations intended to protect research subjects impede scientific advancements needed to treat the critically ill and injured and balancing these regulatory priorities is challenging in the acute setting. This scoping review attempted to systematically identify what regulations are challenging in conducting trauma and emergency research. A systematic search of PubMed was performed to identify studies published between 2007 and 2020, from which 289 articles that address regulatory challenges in conducting research in emergency settings were included. Data were extracted and summarized using descriptive statistics and a narrative synthesis of the results. The review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. Most articles identified were mentary (31%) and published in the USA (49%). Regulatory factors addressed in the papers were categorized under 15 regulatory challenge areas: informed consent (78%), research ethics (65%), institutional review board (55%), human subjects protection (54%), enrollment (53%), exception from informed consent (51%), legally authorized representative (50%), patient safety munity consultation (40%), waiver of informed consent (40%), recruitment challenges (39%), patient perception (30%), liability (15%), participant incentives (13%), mon rule (11%). We identified several regulatory barriers to conducting trauma and emergency research. This summary will support the development of best practices for investigators and funding agencies.

Human menstrual blood-derived mesenchymal stem cells (MenSCs) and their secreted small extracellular vesicles (EVs) had been proven to relieve inflammation, tissue damage, and fibrosis in various organs. The microenvironment induced by inflammatory cytokines can promote mesenchymal stem cells (MSCs) to secrete more substances (including EVs) that could regulate inflammation. Inflammatory bowel disease (IBD) is a chronic idiopathic intestinal inflammation, the etiology and mechanism of which are unclear. At present, the existing therapeutic methods are ineffective for many patients and have obvious side effects. Hence, we explored the role of tumor necrosis factor

Transplantation of Umbilical Cord-Derived Mesenchymal Stem Cells Attenuates Surgical Wound-Induced Blood-Brain Barrier Dysfunction in Mice.
Blood-brain barrier (BBB) is the most ponent of central nervous system (CNS) to keep toxins and pathogens from CNS. Although our studies demonstrated that using interleukin-6 antibodies (IL-6-AB) reversed the increased permeability of BBB, IL-6-AB is limited in their application that only could be used a few hours before surgery and seemed delayed the surgical wounds healing process, which urges us to find another more effective method. In this study, we employed the C57BL/6J female mice to investigate the potential effects of umbilical cord-derived mesenchymal stem cells (UC-MSCs) transplantation on BBB dysfunction induced by surgical wound. Compared to IL-6-AB, the transplantation of UC-MSCs more effectively decreased the BBB permeability after surgical wound evaluated by dextran tracer (immunofluorescence imaging and luorescence quantification). In addition, UC-MSCs can largely decrease the ratio of proinflammatory cytokine IL-6 to the anti-inflammatory cytokine IL-10 in both serum and brain tissue after surgical wound. Moreover, UC-MSCs successfully increased the levels of tight junction proteins (TJs) in BBB such as ZO-1, Occludin, and Claudin-5 and extremely decreased the level of matrix metalloproteinase-9 (MMP-9). Interestingly, UC-MSCs treatment also had positive effects on wound healing while protecting the BBB dysfunction induced by surgical pared to IL-6-AB treatment. These findings suggest that UC-MSCs transplantation is a highly efficient and promising approach on protecting the integrity of BBB which caused by peripheral traumatic injuries.

Kerosene Biodegradation by Highly Efficient Indigenous Bacteria Isolated From Hydrocarbon-Contaminated Sites.
Kerosene is widely used in Ethiopia as a household fuel (for lighting and heating), as a solvent in paint and grease, and as a lubricant in glass cutting. It causes environmental pollution and escorts to loss of ecological functioning and health problems. Therefore, this research was designed to isolate, identify, and characterize indigenous kerosene-degrading bacteria that are effective in cleaning ecological units that have been contaminated by kerosene. Soil samples were collected from hydrocarbon-contaminated sites (flower farms, garages, and old-aged asphalt roads) and spread-plated on mineral salt medium (Bushnell Hass Mineral Salts Agar Medium: BHMS), which consists of kerosene as the only carbon source. Seven kerosene-degrading bacterial species were isolated, 2 from flower farms, 3 from garage areas, and 2 from asphalt areas. Three genera from hydrocarbon-contaminated sites were identified, including

Cooperation between primary cilia signaling and integrin receptor extracellular matrix engagement regulates progenitor proliferation and neuronal differentiation in the developing cerebellum.
Neural progenitors and their neuronal progeny are bathed in extrinsic signals that impact critical decisions like the mode of cell division, how long they should reside in specific neuronal laminae, when to differentiate, and the timing of migratory decisions. Chief among these signals are secreted morphogens and extracellular matrix (ECM) molecules. Among the many cellular organelles and cell surface receptors that sense morphogen and ECM signals, the primary cilia and integrin receptors are some of the most important mediators of extracellular signals. Despite years of dissecting the function of cell-extrinsic sensory pathways in isolation, recent research has begun to show that key pathways work together to help neurons and progenitors interpret diverse inputs in their germinal niches. This mini-review utilizes the developing cerebellar granule neuron lineage as a model that highlights evolving concepts on the crosstalk between primary cilia and integrins in the development of the most abundant neuronal type in the brains of mammals.

Protein sorting from endosomes to the TGN.
Retrograde transport from endosomes to the trans-Golgi network is essential for recycling of protein and lipid cargoes to counterbalance anterograde membrane traffic. Protein cargo subjected to retrograde traffic include lysosomal acid-hydrolase receptors, SNARE proteins, processing enzymes, nutrient transporters, a variety of other transmembrane proteins, and some extracellular non-host proteins such as viral, plant, and bacterial toxins. Efficient delivery of these protein cargo molecules depends on sorting machineries selectively recognizing and concentrating them for their directed retrograde transport from partments. In this review, we outline the different retrograde transport pathways governed by various sorting machineries involved in endosome-to-TGN transport. In addition, we discuss how this transport route can be analyzed experimentally.

Practical tips for navigating a program director transition.
Residency and fellowship program directors profoundly impact trainees, institutions, and patient safety. Yet, there is concern for rapid attrition in the role. The average program director tenure is only 4-7 years, and that timeline is likely a result of burnout or opportunities for career advancement. Program director transitions must be carefully executed to ensure minimal disruption to the program. Transitions benefit from munication with trainees and other stakeholders, well-planned successions or searches for a replacement, and clearly delineated expectations and responsibilities of the outgoing program director. In this Practical Tips, four former residency program directors offer a roadmap for a successful program director transition, with specific mendations to guide critical decisions and steps in the process. Themes emphasized include readiness for a munication strategies, alignment of program mission and search efforts, and anticipatory support to ensure the success of the new director.

Catenin signaling controls phrenic motor neuron development and function during a narrow temporal window.
Phrenic Motor Column (PMC) neurons are a specialized subset of motor neurons (MNs) that provide the only motor innervation to the diaphragm muscle and are therefore essential for survival. Despite their critical role, the mechanisms that control phrenic MN development and function are not well understood. Here, we show that catenin-mediated cadherin adhesive function is required for multiple aspects of phrenic MN development. Deletion of β- and γ-

The benefits of adipocyte metabolism in bone health and regeneration.
Patients suffering from musculoskeletal diseases must cope with a diminished quality of life and an increased burden on medical expenses. The interaction of immune cells and mesenchymal stromal cells during bone regeneration is one of the key requirements for the restoration of skeletal integrity. While stromal cells of the osteo-chondral lineage support bone regeneration, an excessive accumulation of cells of the adipogenic lineage is thought to promote low-grade inflammation and impair bone regeneration. Increasing evidence indicates that pro-inflammatory signaling from adipocytes is responsible for various chronic musculoskeletal diseases. This review aims to summarize the features of bone marrow adipocytes by phenotype, function, secretory features, metabolic properties and their impact on bone formation. In detail, the master regulator of adipogenesis and prominent diabetes drug target, peroxisome proliferator-activated receptor γ (PPARG), will be debated as a potential therapeutic approach to enhance bone regeneration. We will explore the possibilities of using clinically established PPARG agonists, the thiazolidinediones (TZDs), as a treatment strategy to guide the induction of a pro-regenerative, metabolically active bone marrow adipose tissue. The impact of this PPARG induced bone marrow adipose tissue type on providing the necessary metabolites to sustain osteogenic-as well as beneficial immune cells during bone fracture healing will be highlighted.

Learned features of antibody-antigen binding affinity.
Defining predictors of antigen-binding affinity of antibodies is valuable for engineering therapeutic antibodies with high binding affinity to their targets. However, this task is challenging owing to the huge diversity in the conformations of plementarity determining regions of antibodies and the mode of engagement between antibody and antigen. In this study, we used the structural antibody database (SAbDab) to identify features that can discriminate high- and low-binding affinity across a 5-log scale. First, we abstracted features based on previously learned representations of protein-protein interactions to derive 'complex' feature sets, which include energetic, statistical, network-based, and machine-learned features. Second, we contrasted plex feature sets with additional 'simple' feature sets based on counts of contacts between antibody and antigen. By investigating the predictive potential of 700 features contained in the plex and simple feature sets, we observed that simple feature sets parably plex feature sets in classification of binding affinity. bining features from all eight feature-sets provided the best classification performance (median cross-validation AUROC and F1-score of 0.72). Of note, classification performance is substantially improved when several sources of data leakage (e.g., homologous antibodies) are not removed from the dataset, emphasizing a potential pitfall in this task. We additionally observe a classification performance plateau across diverse featurization approaches, highlighting the need for additional affinity-labeled antibody-antigen structural data. The findings from our present study set the stage for future studies aimed at multiple-log enhancement of antibody affinity through feature-guided engineering.

Large Pontine Cavernoma Operated by Anterior Petrosal Approach-Two-Dimensional Operative Video.
Brainstem cavernoma is a challenging neurosurgical pathology and microsurgery remains the only treatment option. Although the decision-making between interventional and conservative approach to this disease may plex, malformations presenting multiple bleedings are usually good candidates for surgery. 1 On the other hand, microsurgical resection of cavernomas can offer an effective resolution with acceptable morbidity. In this video, we present a case of pontine cavernoma with multiple hemorrhages in a young patient. The anatomical characteristic of the lesion defines the best suitable craniotomy for surgery. In this case, an anterior petrosal approach 2 3 4 was used to access the peritrigeminal area and safely perform the resection. Anatomical considerations are described on this skull base approach along with the rationale and benefits of this exposure. Electrophysiological neuromonitoring is essential for this kind of procedure and preoperative tractography also enabled the best understanding of the disease. Finally, we also discuss alternative managements and plications. 5 With the patient's consent, we also show the excellent clinical evolution after few weeks of recovery and the restoration of the corticospinal tract, previously displaced by the cavernoma, to its original position.

Risk Factors and Functional Outcomes with Early Neurological Deterioration after Mechanical Thrombectomy for Acute Large Vessel Occlusion Stroke.
Early neurological deterioration (END) is associated with a poor survival after mechanical thrombectomy (MT) in acute ischemic stroke (AIS). To assess risk factors and functional es of END after MT in patients, we analyzed data from 79 patients who received MT with large-vessel occlusion. END after MT in patients is defined as an increase of two points or more in the National Institute of Health Stroke Scale (NIHSS) pared with the best neurological status within 7 days. The mechanism of END can be classified into: AIS progression, sICH, and encephaledema. A total of 32 AIS patients (40.5%) had END after MT. Risk factors for END after MT included: history of oral antiplatelet and/or anticoagulation drugs before MT (OR = 9.56,95% CI = 1.02-89.57), higher NIHSS score when admitted to hospital (OR = 1.24, 95% CI = 1.04-1.48), under the subtype of atherosclerotic stroke (OR = 17.36, 95% CI = 1.51-199.56), ASITN/SIR< 2 (OR = 15.78, 95% CI = 1.65-151.26), and prolonged period from AIS onset to the first revascularization (OR = 1.01, 95% CI = 1.00-1.02). AIS patients who had END at early stages were more likely to experience poor es (Modified Rankin Scale [mRS] >2) at 90 days after MT (OR = 6.829, 95% CI = 1.573-29.655). Thus, AIS patients who had experienced END at early stages were more likely to have poor es (mRS >2) at 90 days after MT, and the risk factors of END were connected to the mechanism of END.

Performance of CRASH and IMPACT Prognostic Models for Traumatic Brain Injury at 12 and 24 Months Post-Injury.
The Corticoid Randomization after Significant Head Injury (CRASH) and International Mission for Prognosis and Analysis of Clinical Trials (IMPACT) prognostic models are the most reported prognostic models for traumatic brain injury (TBI) in the scientific literature. However, these models were developed and validated to predict 6-month unfavorable e and mortality, and growing evidence supports continuous improvements in functional e after severe TBI up to 2 years post-injury. The purpose of this study was to evaluate CRASH and IMPACT model performance beyond 6 months post-injury to include 12 and 24 months post-injury. Discriminative validity remained consistent over time parable to earlier recovery time points (area under the curve = 0.77-0.83). Both models had poor fit for unfavorable es, explaining less than one quarter of the variation in es for severe TBI patients. The CRASH model had significant values for the Hosmer-Lemeshow test at 12 and 24 months, indicating poor model fit past the previous validation point. There is concern in the scientific literature that TBI prognostic models are being used by neurotrauma clinicians to support clinical decision making despite the goal of the models' development being to support research study design. The results of this study indicate that the CRASH and IMPACT models should not be used in routine clinical practice because of poor model fit that worsens over time and the large, unexplained variance in es.

Variability Across Caregiver and Performance-Based Measures of Executive Functioning in an Acute Pediatric Neurocritical Care Population.
Youth admitted to the pediatric intensive care unit (PICU) for traumatic brain injury monly struggle with long-term residual effects in the domains of physical, cognitive, emotional, and psychosocial/family functioning. In the cognitive domain, executive functioning (EF) deficits are often observed. The Behavior Rating Inventory of Executive Functioning, Second Edition (BRIEF-2) is a pleted measure that is regularly utilized to assess caregivers' perspectives of daily EF abilities. Using pleted measures like the BRIEF-2 in isolation as e measures for capturing symptom presence and severity might be problematic given that caregiver ratings are vulnerable to influence from external factors. As such, this study aimed to investigate the association between the BRIEF-2 and performance-based measures of EF in youth during the acute recovery period post-PICU admission for TBI. A secondary aim was to explore associations among potential confounding factors, including family-level distress, injury severity, and the impact of pre-existing neurodevelopmental conditions. Participants included 65 youths, 8-19 years of age, admitted to the PICU for TBI, who survived hospital discharge and were referred for follow-up care. Non-significant correlations were found between BRIEF-2 es and performance-based measures of EF. Measures of injury severity were strongly correlated with scores from performance-based EF measures, but not BRIEF-2. Parent/caregiver-reported measures of their own health-related quality of life were related to caregiver responses on the BRIEF-2. Results demonstrate the differences captured by performance-based versus caregiver-report measures of EF, and also highlight the importance of considering other morbidities related to PICU admission.

The Art of Holding Perinatal Women in Distress.
Therapies like cognitive behavioral therapy and interpersonal psychotherapy are regarded as highly effective treatments for perinatal mood and anxiety disorders. Therapists appreciate robust research supporting the efficacy of these evidenced-based treatments and the structure of the tools these therapies provide for effective intervention. Less has been written on supportive psychotherapeutic techniques and few of those writings provide instruction or tools for therapists who wish to strengthen their skills in this therapeutic approach. This article describes The Art of Holding Perinatal Women in Distress™, a model of perinatal treatment developed by Karen Kleiman, MSW, LCSW. Kleiman instructs therapists to incorporate six "Holding Points" into their approach to therapeutic assessment and intervention for the purpose of establishing a holding environment conducive to the release of

Time-Dependent Changes in the Biofluid Levels of Neural Injury Markers in Severe Traumatic Brain Injury Patients-Cerebrospinal Fluid and Cerebral Microdialysates: A Longitudinal Prospective Pilot Study.
Monitoring protein biomarker levels in the cerebrospinal fluid (CSF) can help assess injury severity and e after traumatic brain injury (TBI). Determining injury-induced changes in the proteome of brain extracellular fluid (bECF) can more closely reflect changes in the brain parenchyma, but bECF is not routinely available. The aim of this pilot study was pare time-dependent changes of S100 calcium-binding protein B (S100B), neuron-specific enolase (NSE), total Tau, and phosphorylated Tau (p-Tau) levels in matching CSF and bECF samples collected at 1, 3, and 5 days post-injury from severe TBI patients (

Virologists' Sex- and Gender-Based Medical Knowledge of COVID-19 Affects Quality of Students' Education.
A sex- and gender-based approach to medical education is important to develop new knowledge and to improve quality of and equality within health care. Results of a systematic survey showed a lack of sex- and gender-based medical education at German medical faculties. The global severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic is affecting people from diverse backgrounds differently, and the reciprocal interactions between biological sex and sociocultural gender aspects with regard to coronavirus disease 2019 (COVID-19) necessitate an intersectional research approach and transfer to medical education.

The Effect of Vitamin D Supplementation for Bone Healing in Fracture Patients: A Systematic Review.
While most literature on vitamin D supplementation in fracture patients focuses on fracture prevention, the effect of vitamin D on bone healing is a much less studied concept. The primary aim of this systematic review was to assess whether vitamin D supplementation in fracture patients improves clinical or radiological plications. The secondary aims were to assess supplementation effect on patient functional e scores and bone mineral density (BMD). A systematic search of all relevant articles was performed using the following databases: MEDLINE, Embase, Google Scholar, and Web of Science. The population selection included human patients with a fresh fracture treated conservatively or operatively. The intervention included any form of vitamin D pared to no supplementation or a placebo. The primary es assessed were clinical or radiological union rates plications arising from the nonunion. The secondary es assessed were functional e scores, BMD scores after treatment, and pain scores. A total of fourteen studies, assessing a total of 2734 patients, were included. Eight studies assessed the effect of vitamin D on clinical or radiological union. Five studies reported no significant difference plication rates when supplementing fracture patients. Alternatively, three studies reported a positive effect with supplementation between the groups. One of these studies found a difference only for early plications (<30 days), but no differences in plications. The other two studies found significant differences in clinical union; however, no changes were observed in radiological union. Six studies investigated functional e scores after supplementation. Four of these studies found no significant differences between most functional e scores. Only three studies reported BMD es, one of which found limited effect on total hip BMD. The overall findings are that vitamin D alone does little to influence fracture healing and subsequent union rates or functional e. The studies suggestive of a positive effect were generally of a lower quality. Further high quality RCTs are needed to justify routine supplementation at the time of fracture.

Research on automatic emergency steering collision avoidance and stability control of intelligent driving vehicle.
In view of the need for emergency steering to avoid collision when the vehicle is in a dangerous scene, and the stability control of the vehicle during collision avoidance. This paper proposes a planning and control framework. A path planner considering the kinematics and dynamics of the vehicle system is used to formulate the safe driving path under emergency conditions. LQR lateral control algorithm is designed to calculate the output steering wheel angle. On this basis, adaptive MPC control algorithm and four-wheel braking force distribution control algorithm are designed to achieve coordinated control of vehicle driving stability and collision avoidance safety. The simulation results show that the proposed algorithm plete the steering collision avoidance task quickly and stably.

Epidemiology of hypertension among adults in Addis Ababa, Ethiopia.
The public health significance of hypertension is increasing in low- and e countries. However, there is limited epidemiological evidence in Ethiopia. We assessed the prevalence of hypertension and explored its predictors among adults in Addis Ababa, Ethiopia. munity-based cross-sectional study was conducted from April to May 2021 among randomly selected adults aged 18-64 years. A face-to-face interview using an adapted STEPwise Approach to NCD Risk Factor Surveillance (STEPS) questionnaire was conducted. Multilevel mixed-effects logistic regression model was fitted to determine factors associated with hypertension. The sample consisted of a total of 600 adults (mean age: 31.2 ± 11.4 years, 51.7% women). The overall age-standardized prevalence of hypertension was 22.1% and 47.8% according to the Seventh Joint National Commission (JNC7) and the 2017 American Heart Association (AHA) guidelines, respectively. About 25.6% were newly diagnosed with hypertension. The age groups of 40-54 years (AOR = 8.97; 95% CI: 2.35,34.23), and 55-64 years (AOR = 19.28; 95% CI: 3.96,93.83) pared to the 18-24 age group, male sex (AOR = 2.90; 95% CI: 1.22,6.87), obesity (AOR = 1.92; 95% CI: 1.02,3.59), abdominal obesity (AOR = 4.26; 95% CI: 1.42,12.81), and very poor sleep quality (AOR = 3.35; 95% CI: 1.15,9.78) were independent predictors of hypertension. This study revealed that the burden of hypertension among adults is very high. Hypertension is independently associated with older age group, male sex, obesity, abdominal obesity, and poor sleep quality. Therefore, the study highlights the need to develop regular blood pressure surveillance programs, weight loss intervention, and improvement of sleep quality.

Qualitative reactions to a low nicotine product standard for cigarettes from adolescents and young adults living in the United States who smoke.
The Biden Administration is considering a low nicotine product standard for cigarettes. This qualitative study examined reactions to a nicotine reduction policy among adolescents and young adults (AYA) who smoke cigarettes. pleting a lab study involving masked exposure either to low nicotine or normal nicotine research cigarettes and unmasked exposure to e-cigarettes varying in nicotine concentration and flavor, we conducted follow-up semi-structured interviews (N = 25) to explore participants' knowledge, attitudes, and perceptions of a low nicotine product standard and their anticipated tobacco use behavior after policy implementation. Interviews were audio-recorded, transcribed verbatim, double-coded, and analyzed using reflexive thematic analysis. Nearly half of participants supported the policy because they thought it would prevent young people from starting smoking and/or would help people quit. Reasons some participants opposed the policy included beliefs that adults should have the choice to smoke or that a nicotine reduction policy is counterintuitive because the government benefits from cigarette sales. Others believed the policy would be ineffective because youth could circumvent the policy (e.g., illicit market) or would increase their smoking to maintain the same nicotine level. Almost half of participants said they would quit smoking while the other half said they would continue smoking, although potentially reduce their smoking. Overall, our qualitative findings point to the need for pre-policy media campaigns targeting AYA who smoke to minimize negative reactions, dispel fears, and correct misperceptions as well as encourage quitting and provide information on accessing cessation resources.

A Rare Observation of Brachymetacarpia and Brachymetatarsia in a Patient with Primary Idiopathic Hypoparathyroidism.
Brachymetacarpia and brachymetatarsia are unique clinical entities associated with numerous rare conditions. Primary hypoparathyroidism is distinct from pseudohypoparathyroidism and pseudopseudohypoparathyroidism by lacking skeletal changes such as short metacarpals or metatarsals. Here, we present a case of a 64-year-old patient with brachymetacarpia and brachymetatarsia presented with hypocalcemic symptoms and signs, bilateral cataracts, and basal ganglia calcifications, subsequently diagnosed with idiopathic primary hypoparathyroidism. This is a rare case describing such an infrequent observation of brachymetacarpia and brachymetatarsia in primary idiopathic hypoparathyroidism.

Chimeric antigen receptor-T cell therapy-related cardiotoxicity in adults and children cancer patients: A clinical appraisal.
Chimeric antigen receptor-T (CAR-T) cells therapies represent an innovative immunological treatment for patients suffering from advanced and refractory onco-hematological malignancies. The infusion of engineered T-cells, exposing chimeric receptors on the cell surface, leads to an immune response against the tumor cells. However, data from clinical trials and observational studies showed the occurrence of a constellation of adverse events related to CAR-T cells infusion, ranging from mild effects to life-threatening plications. In particular, CAR-T cell-related cardiovascular toxicities represent an emerging group of adverse events observed in these patients, correlated with increased morbidity and mortality. Mechanisms involved are still under investigation, although the aberrant inflammatory activation observed in cytokine release syndrome (CRS) seems to play a pivotal role. The most frequently reported cardiac events, observed both in adults and in the pediatric population, are represented by hypotension, arrhythmias and left ventricular systolic dysfunction, sometimes associated with overt heart failure. Therefore, there is an increasing need to understand the pathophysiological basis of cardiotoxicity and risk factors related to its development, in order to identify most vulnerable patients requiring a close cardiological monitoring and long-term follow-up. This review aims at highlighting CAR-T cell-related plications and clarifying the pathogenetic ing at play. Moreover, we will shed light on surveillance strategies and cardiotoxicity management protocols, as well as on future research perspectives in this expanding field.

The cross-racial/ethnic gesture production of young autistic children and their parents.
Early gesture plays an important role in prelinguistic/emerging munication and may provide insight into a child's munication skills before the emergence of spoken language. Social interactionist theories suggest children learn to gesture through daily interactions with their social environment (e.g., their parents). As such, it is important to understand how parents gesture within interactions with their children when studying child gesture. Parents of typically developing (TD) children exhibit cross-racial/ethnic differences in gesture rate. Correlations between parent and child gesture rates arise prior to the first birthday, although TD children at this developmental level do not yet consistently exhibit the same cross-racial/ethnic differences as their parents. While these relationships have been explored in TD children, less is known about the gesture production of young autistic children and their parents. Further, studies of autistic children have historically been conducted with predominantly White, English-speaking participants. As a result, there is little data regarding the gesture production of young autistic children and their parents from diverse racial/ethnic backgrounds. In the present study, we examined the gesture rates of racially/ethnically diverse autistic children and their parents. Specifically, we explored (1) cross-racial/ethnic differences in the gesture rate of parents of autistic children, (2) the correlation between parent and child gesture rates, and (3) cross-racial/ethnic differences in the gesture rates of autistic children.

Age-dependent phenotypic modulation of smooth muscle cells in the normal ascending aorta.
Ascending aortic aneurysms are associated with pre-existing conditions, including connective tissue disorders (i.e., Marfan syndrome) and bicuspid aortic valves. The underlying mechanisms remain uncertain. Even less is known regarding ascending aortic aneurysms in individuals with normal (i.e., tricuspid) aortic valves (TAV), and without known aneurysm-associated disorders. Regardless of etiology, the risk of plications increases with biological age. Phenotypic modulation of smooth muscle cells (SMCs) is a feature of ascending aortic aneurysms, whereby contractile SMCs are replaced with synthetic SMCs that are capable of degrading the aortic wall. We asked whether age itself causes dysfunctional SMC phenotype modulation, independent of aortic dilatation or pre-existing aneurysm-associated diseases.

Association of arterial stiffness with a prothrombotic state in uncomplicated nondiabetic hypertensive patients.
Past studies reported a significant contribution of a prothrombotic state to the development and progression of target organ damage in hypertensive patients. Stiffening of arterial vessels is associated with aging and hypertension, and additional factors could contribute to this process. This study was designed to examine the relationships between arterial stiffening and the hemostatic and fibrinolytic system.

microRNAs as biomarkers of risk of major adverse cardiovascular events in atrial fibrillation.
Atrial fibrillation is plex and multifactorial disease. Although prophylactic anticoagulation has great benefits in orbidities, adverse cardiovascular events still occur and thus in recent decades, many resources have been invested in the identification of useful markers in the prevention of the risk of MACE in these patients. As such, microRNAs, that are small non-coding RNAs whose function is to regulate gene expression post-transcriptionally, have a relevant role in the development of MACE. miRNAs, have been investigated for many years as potential non-invasive biomarkers of several diseases. Different studies have shown their utility in the diagnosis and prognosis of cardiovascular diseases. In particular, some studies have associated the presence of certain miRNAs in plasma with the development of MACE in AF. Despite these results, there are still many efforts to be done to allow the clinical use of miRNAs. The lack of standardization concerning the methodology in purifying and detecting miRNAs, still provides contradictory results. miRNAs also have a functional impact in MACE in AF through the dysregulation of immunothrombosis. Indeed, miRNAs may be a link between MACE and inflammation, through the regulation of neutrophil extracellular traps that are a key element in the establishment and evolution of thrombotic events. The use of miRNAs as therapy against thromboinflammatory processes should also be a future approach to avoid the occurrence of MACE in atrial fibrillation.

Indoxyl sulfate induces left ventricular hypertrophy
Patients with chronic kidney disease (CKD) have a high risk of left ventricular hypertrophy (LVH). Fibroblast growth factor 23 (FGF23) and indoxyl sulfate (IS) are associated with LVH in patients with CKD, but the interactions between these molecules remain unknown. We investigated whether IS contributes to LVH associated with FGF23 in cultured cardiomyocytes and CKD mice.

Pregnancy loss and risk of incident CVD within 5 years: Findings from the Women's Health Initiative.
Previous studies have demonstrated an increased risk of cardiovascular disease (CVD) in women with a history of pregnancy loss. Less is known about whether pregnancy loss is associated with age at the onset of CVD, but this is a question of interest, as a demonstrated association of pregnancy loss with early-onset CVD may provide clues to the biological basis of the association, as well as having implications for clinical care. We conducted an age-stratified analysis of pregnancy loss history and incident CVD in a large cohort of postmenopausal women aged 50-79 years old.

The Health and Fitness Characteristics of Civilian Jailer Recruits Prior to Academy Training.
Civilian jailer (CJ) recruits may plete fitness testing within their hiring process. As certain job tasks in custody/jail facilities can be physically demanding (e.g., inmate restraint), better health and fitness should help a recruit graduate from a CJ academy and be prepared for the occupation. This study investigated the health and fitness characteristics of CJ recruits entering academy training, detailed between-sex differences, and categorized recruits relative to population norms. Retrospective analysis was conducted on data from 89 CJ recruits (48 males, 41 females) across three academy classes from one law enforcement agency. The following were measured before academy: resting heart rate (RHR); blood pressure (BP); height, body mass, and body mass index (BMI); waist circumference; sit-and-reach; grip strength; 60-s pushups; and YMCA step test recovery heart rate (HR).

Analysis of Total and Segmental Body Composition Relative to Fitness Performance Measures in Law Enforcement Recruits.
Law enforcement agencies often test the fitness performance and position of ing recruits. This study investigated the relationships between whole and segmental position, and fitness tests in law enforcement recruits. A retrospective analysis of 72 male and 11 female recruits was performed. Bioelectrical impedance analysis (BIA) variables were: lean mass (LM), upper-extremity lean mass (UELM), trunk LM, lower-extremity lean mass (LELM), fat mass (FM), upper-extremity fat mass (UEFM), trunk FM, and lower-extremity fat mass (LEFM). Fitness tests included: vertical jump (VJ), peak anaerobic power (PAPw), 75-yard pursuit run (75PR), push-ups, sit-ups, 2-kg medicine ball throw (MBT), and the multi-stage fitness test (MSFT). Partial correlations and ANCOVAs between quartiles assessed relationships between position and performance. Significant moderate-to-large relationships were found; LM, UELM, trunk LM, LELM all related to PAPw (

Circulating tumor DNA: toward evolving the clinical paradigm of pancreatic ductal adenocarcinoma.
Over a decade of sequencing-based genomics research has unveiled a diverse somatic mutation landscape across patients with pancreatic ductal adenocarcinoma (PDAC), and the identification of druggable mutations has aligned with the development of novel targeted therapeutics. However, despite these advances, direct translation of years of PDAC genomics research into the clinical care of patients remains a critical and unmet need. Technologies that enabled the initial mapping of the PDAC mutation landscape, namely whole-genome and transcriptome sequencing, remain overly expensive in terms of both time and financial resources. Consequentially, dependence on these technologies to identify the relatively small subset of patients with actionable PDAC alterations has greatly impeded enrollment for clinical trials testing novel targeted therapies. Liquid biopsy tumor profiling using circulating tumor DNA (ctDNA) generates new opportunities by ing these challenges while further addressing issues particularly relevant to PDAC, namely, difficulty of obtaining tumor tissue via fine-needle biopsy and the need for faster turnaround time due to rapid disease progression. Meanwhile, ctDNA-based approaches for tracking disease kinetics with respect to surgical and therapeutic interventions offer a means to elevate the current clinical management of PDAC toward higher granularity and accuracy. This review provides a clinically focused summary of ctDNA advances, limitations, and opportunities in PDAC and postulates ctDNA sequencing technology as a catalyst for evolving the clinical decision-making paradigm of this disease.

Status of PSMA-targeted radioligand therapy in prostate cancer: current data and future trials.
Metastatic prostate cancer continues to be an incurable disease. Despite all the novel therapies approved in the past two decades, overall patient es remain relatively poor, and these patients die on a regular basis. Clearly, improvements in current therapies are needed. Prostate-specific membrane antigen (PSMA) is a target for prostate cancer given its increased expression on the surface of the prostate cancer cells. PSMA small molecule binders include PSMA-617 and PSMA-I&T and monoclonal antibodies such as J591. These agents have been linked to different radionuclides including beta-emitters such as lutetium-177 and alpha-emitters such as actinium-225. The only regulatory-approved PSMA-targeted radioligand therapy (PSMA-RLT) to date is lutetium-177-PSMA-617 in the setting of PSMA-positive metastatic castration-resistant prostate cancer that has failed androgen receptor pathway inhibitors and taxane chemotherapy. This approval was based on the phase III VISION trial. Many other clinical trials are evaluating PSMA-RLT in various settings. Both monotherapy bination studies are underway. This article summarizes pertinent data from recent studies and provides an overview of human clinical trials in progress. The field of PSMA-RLT is rapidly evolving, and this therapeutic approach will likely play an increasingly important role in the years e.

Clinical outcomes of volume of disease on patients receiving enzalutamide
Androgen receptor signaling inhibitors (ARSis) abiraterone acetate (AA) plus prednisone and enzalutamide (Enza), are currently the most administered first-line treatments for metastatic castration-resistant prostate cancer (mCRPC). AA and Enza have shown similar overall survival (OS) benefits and there is no consensus upon the best option for mCRPC first-line treatment. Volume of disease may represent a useful biomarker to predict response to therapy in such patients.

Interscalene Block in an Anesthetized Adult with Hypertrophic Obstructive Cardiomyopathy Undergoing Clavicle Fracture Reduction.
Whether regional anesthesia procedures should be performed in heavily sedated/anesthetized adults remains controversial. One of the purported advantages of performing regional nerve blocks in conversant patients is early warning against major nerve injury and, arguably, early detection of local anesthetic systemic toxicity. A 60-year-old man with hypertrophic obstructive cardiomyopathy (HOCM) underwent a clavicle fracture repair under general anesthesia. Intraoperative transesophageal echocardiography revealed dynamic left ventricular outflow track obstruction and systolic anterior motion of the posterior mitral valve leaflet. In part based on such echo findings, he received an ultrasound-guided interscalene plus a superficial cervical plexus block for postoperative analgesia prior to emergence from general anesthesia. Given the lack of robust data on the safety of ultrasound-guided regional techniques in heavily sedated/anesthetized adults, we use the example of echographic evidence of significant HOCM to argue for a pragmatic and individualized approach when faced with unusual situations in which the pros of such an approach may outweigh the cons - in this case for performing an interscalene block on an anesthetized adult.

Can the Use of Bedside Lung Ultrasound Reduce Transmission Rates in The Case of The COVID-19 Patient? - A Narrative Review.
Novel Corona Virus Disease-19 (nCov-19, COVID-19) was recognised as a pandemic by the World Health Organization on March 11, 2020. As of June 14, 2020, this contagious viral disease has afflicted 188 out of 195 countries in the world with 7,893,700 confirmed cases and 432,922 global deaths.Canada has 98,787 people infected and 8,146 deaths. COVID-19 is thought to transmit through contact, droplets and aerosolization. A rapid review showed limited information on the benefits of conducting lung ultrasound (LUS) versus chest radiograph (CXR) or studies correlating lung ultrasound to puted Tomography (CT) in patients positive for Covid-19. The literature review confirmed that CT and LUS cannot diagnose this disease, but that both can help in the management and staging of this disease. There is no literature to prove that LUS at the bedside may be beneficial from the view of decreased transmission to other health care workers and bystanders due to reduced transit paring the transit pathway and contact leads one to propose that this would be so. Pregnant patients with COVID-19, young children and patients in the reproductive stage would also benefit from LUS since there is no radiation dose and the critical patient in distress will benefit from testing at the bedside.

Resuscitation of traumatic maternal cardiac arrest: A case report and summary of recommendations from Obstetric Life Support™.
Traumatic maternal cardiac arrest (MCA) is a challenging scenario for the healthcare team. Expanding the focused assessment with sonography for trauma (FAST) and modifying cardiopulmonary resuscitation (CPR) is necessary. ponents in the resuscitation of reproductive-age women with traumatic cardiac arrest are highlighted using mendations from Obstetric Life Support™. A morbidly obese female presented to the Emergency Department (ED) with ongoing CPR and massive hemorrhage from two gunshot wounds to the chest. Ultrasound used during secondary survey, revealed an intrauterine pregnancy, with uterine fundus palpated above the umbilicus. Four minutes after arrival at the ED, the trauma surgeon initiated a resuscitative cesarean delivery (RCD) by transverse abdominal incision. The on-call pleted the procedure, and the neonate was resuscitated and transferred to the neonatal intensive care unit (NICU). Multiple agents and surgical techniques were required to control ongoing uterine and abdominal wall hemorrhage during intermittent return of spontaneous circulation (ROSC). Despite ongoing CPR and management of the patient's chest, pelvic and abdominal wounds, eventually, there was no return of cardiac activity, no organized cardiac rhythm, no measurable end-tidal carbon dioxide, and no palpable pulse. Further resuscitation and initiation of extracorporeal cardiopulmonary resuscitation (ECPR) were deemed futile by the multidisciplinary team and stopped at the 60-minute mark. Our case summarizes essential techniques addressing MCA mended in OBLS™ courses. Including 1) expanding the FAST exam to assess for pregnancy status, 2) estimating gestational age by fundal height or point-of-care ultrasound, 3) performing a RCD via midline vertical incision at 4 min if pregnancy is suspected to be ≥20 weeks' gestation (fundal height at or above the umbilicus, femoral length of ≥30 mm or biparietal diameter of ≥45 mm), and 4) execution of ECPR for refractory cardiac arrest.

Elucidating the role of key physio-biochemical traits and molecular network conferring heat stress tolerance in cucumber.
Cucumber is an important vegetable crop grown worldwide and highly sensitive to prevailing temperature condition. The physiological, biochemical and molecular basis of high temperature stress tolerance is poorly understood in this model vegetable crop. In the present study, a set of genotypes with contrasting response under two different temperature stress (35/30°C and 40/35°C) were evaluated for important physiological and biochemical traits. Besides, expression of the important heat shock proteins (HSPs), aquaporins (AQPs), photosynthesis related genes was conducted in two selected contrasting genotypes at different stress conditions. It was established that tolerant genotypes were able to maintain high chlorophyll retention, stable membrane stability index, higher retention of water content, stability in net photosynthesis, high stomatal conductance and transpiration bination with less canopy temperatures under high temperature stress pared to susceptible genotypes and were considered as the key physiological traits associated with heat tolerance in cucumber. Accumulation of biochemicals like proline, protein and antioxidants like SOD, catalase and peroxidase was the underlying biochemical mechanisms for high temperature tolerance. Upregulation of photosynthesis related genes, signal transduction genes and heat responsive genes (HSPs) in tolerant genotypes indicate the molecular network associated with heat tolerance in cucumber. Among the HSPs, higher accumulation of HSP70 and HSP90 were recorded in the tolerant genotype, WBC-13 under heat stress condition indicating their critical role. Besides,

Proteome and phosphoproteome analysis of 2,4-epibrassinolide-mediated cold stress response in cucumber seedlings.
The 2, 4-epibrassinolide (EBR) significantly increased plants cold tolerance. However, mechanisms of EBR in regulating cold tolerance in phosphoproteome and proteome levels have not been reported. The mechanism of EBR regulating cold response in cucumber was studied by multiple omics analysis. In this study, phosphoproteome analysis showed that cucumber responded to cold stress through multi-site serine phosphorylation, while EBR further upregulated single-site phosphorylation for most of cold-responsive phosphoproteins. Association analysis of the proteome and phosphoproteome revealed that EBR reprogrammed proteins in response to cold stress by negatively regulating protein phosphorylation and protein content, and phosphorylation negatively regulated protein content in cucumber. Further functional enrichment analysis of proteome and phosphoproteome showed that cucumber mainly upregulated phosphoproteins related to spliceosome, nucleotide binding and photosynthetic pathways in response to cold stress. However, different from the EBR regulation in omics level, hypergeometric analysis showed that EBR further upregulated 16 cold-up-responsive phosphoproteins participated photosynthetic and nucleotide binding pathways in response to cold stress, suggested their important function in cold tolerance. Analysis of cold-responsive transcription factors (TFs) by correlation between proteome and phosphoproteome showed that cucumber regulated eight class TFs may through protein phosphorylation under cold stress. bined with cold-related transcriptome found that cucumber phosphorylated eight class TFs, and mainly through targeting major hormone signal genes by bZIP TFs in response to cold stress, while EBR further increased these bZIP TFs (CsABI5.2 and CsABI5.5) phosphorylation level. In conclusion, the EBR mediated schematic of molecule response mechanisms in cucumber under cold stress was proposed.

Mini-review: Lipid flippases as putative targets for biotechnological crop improvement.
An increasing world population and drastic changes in weather conditions are challenging agricultural production. To face these challenges and ensure sustainable food production in the future, crop plants need to be improved to withstand several different biotic and abiotic stresses. Commonly, breeders select varieties that can tolerate a specific type of stress and then cross these varieties to stack beneficial traits. This strategy is time-consuming and strictly dependent on the stacked traits been genetically unlinked. Here, we revise the role of plant lipid flippases of the P4 ATPase family in stress-related responses with a special focus on the pleiotropic nature of their functions and discuss their suitability as biotechnological targets for crop improvement.

Comparative analysis of drought stress-induced physiological and transcriptional changes of two black sesame cultivars during anthesis.
Sesame production is severely affected by unexpected drought stress during flowering stage. However, little is known about dynamic drought-responsive mechanisms during anthesis in sesame, and no particular attention was given to black sesame, the mon ingredient in East Asia traditional medicine. Herein, we investigated drought-responsive mechanisms of two contrasting black sesame cultivars (Jinhuangma, JHM, and Poyanghei, PYH) during anthesis. Compared to PYH, JHM plants showed higher tolerance to drought stress through the maintenance of biological membrane properties, high induction of osmoprotectants' biosynthesis and accumulation, and significant enhancement of the activities of antioxidant enzymes. For instance, the drought stress induced a significant increase in the content of soluble protein (SP), soluble sugar (SS), proline (PRO), glutathione (GSH), as well as the activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) in leaves and roots of JHM pared to PYH plants. RNA sequencing followed by differentially expressed genes (DEGs) analysis revealed that more genes were significantly induced under drought in JHM than in PYH plants. Functional enrichment analyses disclosed that several pathways related to drought stress tolerance, such as photosynthesis, amino acids and fatty acid metabolisms, peroxisome, ascorbate and aldarate metabolism, plant hormone signal transduction, biosynthesis of secondary metabolites, and glutathione metabolism, were highly stimulated in JHM than in PYH plants. Thirty-one (31) key highly induced DEGs, including transcription factors and glutathione reductase and ethylene biosynthetic genes, were identified as potential candidate genes for improving black sesame drought stress tolerance. Our findings show that a strong antioxidant system, biosynthesis and accumulation of osmoprotectants, TFs (mainly ERFs and NACs), and phytohormones are essential for black sesame drought tolerance. Moreover, they provide resources for functional genomic studies toward molecular breeding of drought-tolerant black sesame varieties.

Giant mixed hemangioma of the breast: A case report with imaging findings.
Hemangioma of the breast is an mon tumor type that is usually small, superficially located, and impalpable. The majority of cases are cavernous hemangiomas. We describe a rare case of a large, palpable mixed hemangioma of the breast which was located in the parenchymal layer, studied with magnetic resonance imaging, mammography, and sonography. Magnetic resonance imaging findings of slow and persistent enhancement from the center to periphery are useful in characterizing benign breast hemangiomas, where even the lesion presents with a suspicious shape and margin on sonography.

Schwannoma-like uterine leiomyoma with fever of unknown origin and surgical management in a middle-aged woman: A case report.
Herein, we describe a 42-year-old woman with multiple uterine leiomyomas with interesting clinical and histologic findings. She had no medical history, except for uterine myomas, which were diagnosed in her early 30s. She presented with fever and lower abdominal pain, and her symptoms did not respond to antibiotics and antipyretics. The clinical evaluation suggested that degeneration of the largest myoma might be the cause of her symptoms, and pyomyoma was suspected. As she had sustained lower abdominal pain, hysterectomy and bilateral salpingectomy were performed. Histopathological examination confirmed the presence of usual-type uterine leiomyomas without suppurative inflammation. The largest tumor showed a rare morphology with a predominant schwannoma-like growth pattern and infarct-type necrosis. Thus, schwannoma-like leiomyoma was diagnosed. This rare tumor might be one of the manifestations of hereditary leiomyomatosis and renal cell cancer syndrome; however, this patient was unlikely to have that rare syndrome. Herein, the clinical, radiological, and pathologic findings of a schwannoma-like leiomyoma are presented and we have raised the question of whether patients with schwannoma-like uterine leiomyoma are more likely to be associated with hereditary leiomyomatosis and renal cell cancer syndrome than those with usual-type uterine leiomyoma.

Posterior urethral valve: A case report in an older Nigerian child.
Posterior urethral valve (PUV) is an anomaly of the urinary tract in male children and is the leading cause of urinary tract obstruction in the pediatric population. PUV is diagnosed radiologically by ultrasonography, both pre- and postnatally, and using micturating cystourethrography. Its prevalence and age of diagnosis may vary by demographic and ethnic background. This case highlights an older Nigerian child that presented with recurrent urinary tract symptoms and was subsequently diagnosed with PUV. The study further explores the key radiographic findings and analyzes the radiographic imaging features of PUV in various populations.

Findings of cholangitis in a kidney transplant patient with Caroli disease on FDG PET/CT and MRI.
Caroli disease is a rare congenital disorder of segmental cystic dilatations of the intrahepatic biliary ducts that munication with the rest of the biliary tree. Its typical clinical presentation is recurrent episodes of cholangitis. The diagnosis is usually made using abdominal imaging modalities. We present a patient with Caroli disease showing atypical presentation of acute cholangitis with ambiguous labs and initial negative imaging findings, which was later diagnosed by [18F]-fluorodeoxyglucose positron emission puted tomography and confirmed by magnetic resonance imaging and tissue pathology. The use of such imaging modalities in moments of doubt or clinical suspicion provide the patient with accurate diagnosis, proper management, and better clinical e, thus obviating the need for further invasive investigations.

High-altitude cerebral edema manifesting as T2/FLAIR hyperintensity and microbleeds in the white matter on MRI brain.
High-altitude cerebral edema is a rare type of acute mountain illness characterized by consciousness disruption and truncal ataxia. Here we discuss a 40-year-old nondiabetic, nonsmoker male who went on a tour to Nanga Parbat. On returning home, the patient developed symptoms of headache, nausea, and vomiting. His symptoms worsened with time and he developed lower limb weakness and shortness of breath. Later, he underwent puterized tomography chest scan. On the basis of CT scan findings, the doctors decided that the patient was suffering from COVID-19 Pneumonia despite having negative COVID-19 PCR tests multiple times. Later, the patient presented to our hospital with plaints. MRI of the brain revealed T2/fluid-attenuated inversion recovery hyperintense and T1 hypointense signals in the bilateral semioval centrum, posterior periventricular white matter, and corpus callosum genu, body, and splenium. These abnormal signals were discovered to be more evident in the corpus callosum's splenium. Moreover, susceptibility-weighted imaging revealed micro hemorrhages in the corpus callosum. This verified the diagnosis that the patient is suffering from high-altitude cerebral edema. Within 5 days, his symptoms resolved and he was discharged with full recovery.

CT and MRI presentation of intradural epidural angiolipoma of the thoracic spinal canal (with a case report).
Epidural angiolipoma is a rare benign tumor consisting of mature adipocytes, blood sinuses, capillaries, and small blood vessels. It constitutes about 0.04%-1.2% of spinal axis tumors and about 2%-3% of extradural spinal tumors. We report a case of thoracic epidural angiolipoma and review the literature. We describe a 42-year-old woman who had weakness and numbness in her lower extremities prior to diagnosis and had an onset of approximately 10 months. The patient was misdiagnosed as schwannoma on preoperative imaging, possibly because neurogenous tumor is the mon intramedullary subdural tumor, and the lesion grew into bilateral intervertebral foramina. However, the lesion demonstrated high signal on the T2-weighted and T2 fat suppression sequences, and the linear low signal at the lesion edge was ignored, leading to misdiagnosis. The patient underwent posterior thoracic 4-6 laminectomy, pathectomy, and spinal pression/vertebroplasty under general anesthesia. The final pathologic diagnosis was intradural epidural angiolipoma of the thoracic vertebra. Spinal epidural angiolipoma is a rare benign tumor that occurs frequently in middle-aged women and is mostly located on the dorsal side of the thoracic spinal canal. Magnetic resonance imaging findings of spinal epidural angiolipoma depend on the ratio of fat to blood vessels. Most angiolipomas show equal or high signal on T1-weighted images and high intensity on T2-weighted images, with significant enhancement after injection of gadolinium. The treatment of spinal epidural angiolipoma plete surgical resection with good prognosis.

Bilateral vertebral artery dissection extending to the left posterior cerebral artery: A case report.
Intracranial artery dissection accounts for a small percentage (1%-2%) of all ischemic strokes. Vertebral artery dissection sometimes extends to the basilar artery but very rarely to the posterior cerebral artery. We report a case of bilateral vertebral artery dissection extending to the left posterior cerebral artery with the characteristic distribution of intramural hematoma. A 51-year-old woman presented with right hemiparesis and dysarthria 3 days after sudden neck pain. Magnetic resonance imaging on admission revealed infarcts in the left thalamus and temporo-occipital lobe and findings suggestive of bilateral vertebral artery dissection. No infarct was detected in the brainstem. The patient was treated conservatively. Initially, we suspected that infarction in the left posterior cerebral artery territory had been caused by artery-to-artery embolism from the dissected vertebral arteries. However, T1-weighted imaging on day 15 of admission revealed intramural hematoma extending from the left vertebral artery to the left posterior cerebral artery. Therefore, we diagnosed bilateral vertebral artery dissection extending to the basilar artery and the left posterior cerebral artery. The patient's symptoms subsequently improved with conservative treatment, and she was discharged with a modified Rankin Scale score of 1 on day 62 of admission. In this case, intramural hematoma of the basilar artery was found in the anterior vessel wall. Brainstem infarction is less likely when intramural hematoma is located in the anterior vessel wall of the basilar artery in vertebrobasilar artery dissection. T1-weighted imaging is useful for the diagnosis of this rare condition and can predict potentially impaired branches and possible symptoms.

Case report of a very rare primary malignant bone tumor: Mixed type maxillary osteosarcoma.
a (OS) is the mon primary malignant bone tumor, accounting for approximately 20% of all primary bone malignancies. OS affects 2-4.8 in 1,000,000 individuals annually and is mon in men than women (1.5:1 ratio). The mon locations include the femur (42%), the tibia (19%), and the humerus (10%), whereas other potential sites include the skull or jaw (8%) and the pelvis (8%). We report a very rare case in a 48-year-old female who presented with swelling of the left cheek panied by palpable solid mass, with the final diagnosis of mixed type maxillary OS was confirmed from a surgical biopsy.
