Background and Aims: Patients with overt or occult hepatitis B virus (HBV) infection receiving immunosuppressive treatments have a wide risk of HBV reactivation (HBVr). We performed meta‐analysis with decision curve analyses (DCA) to estimate the risk of HBVr in HBsAg‐negative anti‐HBc‐positive patients naïve to nucleos(t)ide analogues (NAs) receiving immunosuppressive treatments. Approach and Results: Studies were identified through literature search until October 2022. Pooled estimates were obtained using random‐effects model. Subgroup analyses were performed according to underlying disease and immunosuppressive treatments. DCA was used to identify the threshold probability associated with the net benefit of antiviral prophylaxis in HBsAg‐negative anti‐HBc‐positive patients. We selected 68 studies (40 retrospective and 28 prospective), including 8034 patients with HBsAg negative anti‐HBc positive. HBVr was 4% (95% CI 3%–6%) in HBsAg‐negative anti‐HBc‐positive patients, with a significantly high heterogeneity (I2 69%; p <.01). The number‐needed‐to‐treat (NNT) by DCA ranged from 8 to 24 for chemotherapy plus rituximab, from 12 to 24 for targeted therapies in cancer patients and from 13 to 39 for immune‐mediated diseases. Net benefit was small for monoclonal antibodies. Conclusions: Our DCA in HBsAg‐negative anti‐HBc‐positive patients provided evidence that NA prophylaxis is strongly recommended in patients treated with chemotherapy combined with rituximab and could be appropriate in patients with cancer treated with targeted therapies and in patients with immune‐mediated diseases. Finally, in patients with cancer treated with monoclonal antibodies or with chemotherapy without rituximab, the net benefit is even lower. [ABSTRACT FROM AUTHOR]

ABSTRACT Virtual reality exposure therapy (VRE) has been used in the treatment of combat‐related PTSD since the late 1990s and was recently adapted to treat PTSD due to military sexual trauma (MST). With content specifically tailored to MST‐related contexts, we present the case study of a military veteran who participated in the open clinical trial examining the feasibility of VRE in the treatment of MST‐related PTSD (Loucks et al. 2019). We illustrate VRE's use in activating the trauma memory to facilitate therapeutic emotional processing across sessions and overall symptom reduction. The case study includes common challenges that may occur during VRE and relevant recommendations. The discussion will include lessons learned from the case study and the open clinical trial, recommendations for the flexible application of VRE, and the ongoing developments in the latest version of the VRE system, informed by feedback acquired from the clinicians and patients who experienced it in the initial clinical trial.

Ras homolog family member A (RhoA) acts as a signaling hub in many cellular processes, including cytoskeletal dynamics, division, migration, and adhesion. RhoA activity is tightly spatiotemporally controlled, but whether downstream effectors share these activation dynamics is unknown. We developed a novel single-color FRET biosensor to measure Rho-associated kinase (ROCK) activity with high spatiotemporal resolution in live cells. We report the validation of the Rho-Kinase Activity Reporter (RhoKAR) biosensor. RhoKAR activation was specific to ROCK activity and was insensitive to PKA activity. We then assessed the mechanisms of ROCK activation in mouse fibroblasts. Increasing intracellular calcium with ionomycin increased RhoKAR activity and depleting intracellular calcium with EGTA decreased RhoKAR activity. We also investigated the signaling intermediates in this process. Blocking calmodulin or CaMKII prevented calcium-dependent activation of ROCK. These results indicate that ROCK activity is increased by calcium in fibroblasts and that this activation occurs downstream of CaM/CaMKII. [ABSTRACT FROM AUTHOR]

Recent research has proposed using positron emission tomography/computed tomography (PET/CT) along with the administration of prostate-specific membrane antigen (PSMA)-targeting radiopharmaceuticals to identify breast cancer (BC) lesions. An extensive literature review to investigate the possible diagnostic utility of PET/CT with PSMA-targeting radiopharmaceuticals in BC patients was performed. The research comprised different clinical scenarios, including both newly diagnosed BC patients and those who had experienced disease relapse. This updated systematic review encompassed six studies investigating the diagnostic efficacy of PSMA-targeted PET/CT in BC. Throughout all clinical settings investigated, the papers presented data demonstrating a modest diagnostic performance of PSMA-targeted PET/CT in different subtypes of BC. In this setting, PSMA-guided PET/CT showed slightly higher accuracy in patients diagnosed with triple-negative BC. Based on the current literature, PSMA-targeted PET/CT cannot be suggested as a diagnostic tool to assess BC extent in any clinical scenario. However, based on the PSMA expression observed in triple-negative patients, it can be proposed as a tool to evaluate whether BC patients could benefit from PSMA-targeting radioligand therapy.

A leading cause of mortality after influenza infection is the development of a secondary bacterial pneumonia. In the absence of a bacterial superinfection, prescribing antibacterial therapies is not indicated but has become a common clinical practice for those presenting with a respiratory viral illness. In a murine model, we found that antibiotic use during influenza infection impaired the lung innate immunologic defenses toward a secondary challenge with methicillin-resistant Staphylococcus aureus (MRSA). Antibiotics augment lung eosinophils, which have inhibitory effects on macrophage function through the release of major basic protein. Moreover, we demonstrated that antibiotic treatment during influenza infection caused a fungal dysbiosis that drove lung eosinophilia and impaired MRSA clearance. Finally, we evaluated 3 cohorts of hospitalized patients and found that eosinophils positively correlated with antibiotic use, systemic inflammation, and worsened outcomes. Altogether, our work demonstrates a detrimental effect of antibiotic treatment during influenza infection that has harmful immunologic consequences via recruitment of eosinophils to the lungs, thereby increasing the risk of developing a secondary bacterial infection.

To identify and confirm patterns of relationships connecting sense of community (SOC) and individual resilience with psychological well‐being, via the mediation of coronavirus disease 2019 (COVID‐19) impacts on life domains. An online survey was conducted with a sample of adults (n = 650) 1 year after the COVID‐19 outbreak in Italy and the United States (April–December 2021). Utilizing a Structural Equation Model, we tested a mediation model (n = 563) to identify the associations between SOC and individual resilience and the perceived impacts of the emergency situation and psychological well‐being. Results revealed that during the crisis, SOC had an influence on psychological well‐being, but only by mediating the effects of COVID‐19 impacts on life domains. Independently, individual resilience had a direct influence on psychological well‐being. The findings support the importance of the interaction of individual and collective variables that played different roles at different phases of the pandemic. The findings suggest for possible interventions to enhance well‐being during crises. [ABSTRACT FROM AUTHOR]

A palladium catalyst supported on silk fibroin (Pd/SF) has been tested in the Sonogashira coupling reactions of a wide range of aryl iodides and terminal alkynes. The best catalytic performance was obtained at 90 °C using only 0.25 mol % metal loading under copper‐free conditions, in the presence of a H2O/EtOH (3 : 2 v/v) solvent mixture and triethylamine as the base, affording the coupling products in good yields. The Pd/SF‐based protocol was then successfully extended to the synthesis of benzofurans through Sonogashira‐Cacchi type annulation of 2‐iodophenol with terminal alkynes. Preliminary investigations on the recyclability and the heterogeneous behaviour of the catalyst were performed: hot filtration test and leaching test evidenced the presence of a small amount of soluble active palladium species into the reaction mixture. Nevertheless, Pd/SF could be reused in recharging test and it can be recycled in four consecutive runs with no significant deactivation. [ABSTRACT FROM AUTHOR]

Simple Summary: Treatment options for intrahepatic cholangiocarcinoma (iCCA), a highly malignant tumor with poor prognosis, are limited. Recent developments in immunotherapy and immune checkpoint inhibitors (ICIs) have offered new hope for treating iCCA. However, several issues remain, including the identification of reliable biomarkers of response to ICIs and immune-based combinations. Tumor immune microenvironment (TIME) of these hepatobiliary tumors has been evaluated and is under assessment in order to boost the efficacy of ICIs and to convert these immunologically "cold" tumors to "hot" tumors. Herein, we examine the role of iCCA TIME, highlighting its mechanisms, current applications and challenges, and future research directions.

Immune checkpoint inhibitors (ICIs), such as durvalumab, tremelimumab, and atezolizumab, have emerged as a significant therapeutic option for the treatment of hepatocellular carcinoma (HCC). In fact, the efficacy of ICIs as single agents or as part of combination therapies has been demonstrated in practice-changing phase III clinical trials. However, ICIs confront several difficulties, including the lack of predictive biomarkers, primary and secondary drug resistance, and treatment-related side effects. Herein, we provide an overview of current issues and future challenges in this setting. [ABSTRACT FROM AUTHOR]

Nasal delivery is a non-invasive strategy for effective drug delivery. Nevertheless, in order to promote drug uptake by the nasal mucosa, it is fundamental to increase its residence time in the administration site. To this aim, nano-sized drug delivery systems are widely exploited. Within this context, the commercially available nanoemulsion for parenteral nutrition is a biocompatible, safe and clinically approved vehicle for drug delivery. Furthermore, the nanodroplet surface can be modified via a well-established protocol to graft Concavalin A, a lectin capable of improving the mucosal adhesion, by binding to the α-mannose and α-glucose residues of the mucosal glycocalyx. The obtained targeted formulation is able to induce haemagglutination, as opposite to non-modified nanoemulsion. Furthermore, the ConA grafting maintains the physicochemical properties of the nanodroplets (size~230 nm, Z < −35 mV) and does not interfere with the loading of the Rose Bengal fluorescent probe. Fluorescently labelled ConA grafted nanodroplets showed enhanced permeation and accumulation in ex vivo bovine nasal mucosa. This study is a proof of concept that Concanavalin A can be used to decorate the surface of nanodroplets, acting as a permeation promoter. [ABSTRACT FROM AUTHOR]

AbstractScientific conferences and meetings are an integral part of careers in research, medicine, education, and many other professional arenas. Such meetings allow professionals and researchers to share their findings, support expansion of professional networks, enhance professional development, and foster new collaborations. However, barriers throughout the conference experience lead to the exclusion of experts with disabilities, deepening existing inequities in the STEMM (science, technology, engineering, mathematics, and medicine) workforce. This is especially problematic for STEMM experts with blindness or low vision, who remain significantly under-represented throughout the health and science ecosystem. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions Olfactory dysfunction (OD) is a key symptom of chronic rhinosinusitis (CRS). Although extensively studied in CRS with nasal polyps (CRSwNP), OD in CRS without nasal polyps (CRSsNP) remains under‐researched. This study aims to assess the prevalence of OD and its evolution in surgically naïve patients with CRSsNP undergoing endoscopic sinus surgery (ESS).This prospective study included 97 participants with CRSsNP (mean age, 46.5 years; 70.1% men) and 97 healthy controls (mean age, 46.5 years; 70.1% men). Participants underwent psychophysical evaluations of orthonasal (using the Sniffin’ Sticks test) and retronasal olfaction (using powdered aromas) at enrolment and 6 months post‐ESS.Out of 97 patients, 81 (83.5%) completed all assessments. At enrolment, 23 (28.4%) CRSsNP patients had OD based on composite threshold, discrimination, identification scores, compared with 7 (8.6%) controls (absolute % difference, 19.8% [95% CI, 8.2–31.4]). Retronasal olfactory function was also significantly worse in CRSsNP patients. Six months post‐ESS, 30 patients (37.0%) experienced a clinically significant improvement in olfactory, whereas nonsignificant changes were observed in retronasal olfactory score, and 3.7% of patients experienced a deterioration of the olfactory function.In conclusion, although 37% of patients experienced a clinically significant improvement in their sense of smell following ESS, the overall prevalence of OD in this surgically naive population appears relatively low, especially when compared to that observed in patients with CRSwNP. Therefore, ESS may offer some benefits for enhancing orthonasal olfactory function, but the extent of these improvements appears to be limited. [ABSTRACT FROM AUTHOR]

A molecular tool has been developed for the molecular identification of Ips sexdentatus (Börner 1776) (Coleoptera Curculionidae Scolytidae), the well-known six thooted bark beetle, widely distributed in Eurasia, where it infests several species of the genus Pinus and occasionally a few conifer species of the genera Abies, Larix and Picea. The developed test can be useful both in countries where I. sexdentatus is handled as a quarantine species and, to greater reason, in Europe to discriminate biological traces of this commonly found beetle from those produced by regulated pests. The protocol is based on real-time PCR with TaqMan probe technology and has been developed on whole insect bodies (adults) as well as on artificial frass contaminated by DNA of the beetle. The molecular test developed here for both direct and indirect identification of I. sexdentatus has proven effective in terms of analytical specificity, analytical sensitivity, reliability and reproducibility. The recommended protocol is a practical diagnostic tool allowing a rapid identification of the six toothed bark beetle in the presence of any biological trace of other xylophagous pests collected at points of entry during phytosanitary surveys.

The relationship between meningiomas and gonadal steroid hormones has been the subject of debate, and there is limited understanding of the connection between patient, tumor characteristics, and progesterone receptor (PGR) status. This retrospective observational study aims to explore the prognostic correlation between PGR+ and PGR-meningiomas in terms of various clinical, radiological, and surgical predictors. The analysis included 270 patients, divided into 2 groups: group A (PGR-, 194 patients), and group B (PGR+, 76 patients). The analysis showed no significant differences in terms of age, sex, clinical debut, postsurgical complications, total resection, and grading between the 2 groups. However, a significant difference was observed in the mean Karnofsky performance status at all stages of follow-up. Peritumoral edema measured in preoperative magnetic resonance imaging significantly influences the value of Karnofsky performance status in both preoperative (ANOVA, P = 0.05) and postoperative evaluation (postoperative ANOVA, P = 0.014) only in group A. In the multivariate analysis, there are no significant factors related to the clinical, biological, and surgical parameters previously examined for each measurement time (P = 0.826). The study found that PGR + meningioma patients tend to have better postoperative recovery and earlier clinical debut without any association with age prevalence or grading. [ABSTRACT FROM AUTHOR]

Purpose: Prostate-Specific Membrane Antigen (PSMA)-targeted Positron Emission Tomography (PET) has revolutionised prostate cancer (PCa) diagnosis and treatment, offering superior diagnostic accuracy over traditional methods and enabling theragnostic applications. However, a significant diagnostic challenge has emerged with identifying unspecific bone uptakes (UBUs), which could lead to over-staging and inappropriate treatment decisions if misinterpreted. This systematic review explores the phenomenon of UBUs in PCa patients undergoing PSMA-PET imaging. Methods: Studies assessing the prevalence, topographical distribution, and potential clinical implications of UBUs were selected according to the Preferred Reporting Items for a Systematic Review and Meta-Analysis (PRISMA) method and evaluated with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Results: The percentage of PCa patients with UBUs on PSMA-PET scans ranged from 0 to 71.7%, depending on the radiopharmaceutical used, with [18F]PSMA-1007 showing the highest incidence. The ribs are the primary site of UBUs across all PSMA-targeted radiopharmaceuticals. The spine is the second most frequent UBU site for [68Ga]Ga-PSMA-11, [18F]DCFPyL, [18F]rhPSMA-7, while the pelvic girdle represents the second most frequent site for [18F]PSMA-1007. The average maximum Standardized Uptake Value (SUVmax) of UBUs varied from 3.4 to 7.7 and was generally lower than that of bone metastases. Conclusions: Our findings underscore the need for heightened awareness and precise interpretation of UBUs to avoid potential over-staging and subsequent inappropriate treatment decisions. Considering the radiopharmaceutical used, PET-derived semiquantitative parameters, the topographical distribution of UBUs, and accurately evaluating the pre-test probability based on clinical and laboratory parameters may aid nuclear medicine physicians in interpreting PSMA-PET findings.

We prove the existence of weak solutions for a class of second-order traffic models with relaxation, without requiring the sub-characteristic stability condition to hold. With the help of numerical simulations, we show how, in this unstable setting, large but bounded oscillations may arise from small perturbations of equilibria, thus reproducing the formation of stop-and-go waves commonly observed in traffic dynamics. An analysis of the corresponding traveling waves completes the study. [ABSTRACT FROM AUTHOR]

1. Salmonella Gallinarum strains isolated from a southern Brazil fowl typhoid outbreak were subjected to phenotypic and genotypic analyses to identify genetic elements that could improve prevention and control strategies.2. Whole-genome sequencing revealed the presence of the aac(6’)-Iaa gene, conferring aminoglycoside resistance, along with novel chromosomal point mutations, including the first detection of parE p.S451F in Salmonella Gallinarum.3. Additionally, IncFII(S) plasmid replicons, Salmonella pathogenicity islands and 105 virulence genes associated with cell adhesion, invasion and antimicrobial peptide resistance were identified.4. These findings shed light on the molecular mechanisms of fowl typhoid and provide crucial insights into emerging antimicrobial resistance and virulence factors. [ABSTRACT FROM AUTHOR]

Despite widely recognised effectiveness against the spread of COVID‐19, vaccine hesitancy persists. This systematic literature review aimed to clarify the definition and the operationalisation of the term 'vaccine hesitancy' and disclose the various psychosocial factors underlying this phenomenon. The results of studies conducted in European countries and in the United States after the vaccines became available were taken into account. The review was conducted according to the Preferred Reporting Items for Systematic Review and Meta‐Analyses statement. Twelve studies met the inclusion criteria and were reviewed. efinitions and measures of vaccine hesitancy differed across the studies, limiting their comparison. Nonetheless, by drawing on theoretical frameworks, we were able to identify several psychosocial variables in determining vaccine hesitancy. Our findings point to the need for a transdisciplinary approach to understanding the antecedents of vaccine hesitancy. A better understanding of the phenomenon may help to develop interventions and social policies to address a complex challenge such as vaccination hesitancy. [ABSTRACT FROM AUTHOR]

Lacustrine environments from Northern Patagonia are exposed to volcanic events from the Southern Volcanic Zone. Chironomid larvae are an important paleo-proxy because, in addition to their environmental sensitivity, their chitinous cephalic capsules are well preserved in lacustrine sediments, allowing their recovery and identification. We analysed the effects of a recent volcanic eruption (Puyehue-Cordón Caulle Volcanic Complex 2011) on the chironomid community based on their cephalic remains accumulated following the ash deposition process. Two pulses of ash deposition were distinguished: a first stage comprising the immediate coarse ash fall and a delayed finer volcanic deposition. An abrupt decline in chironomid taxa and their densities were noted during the first coarse pulse, followed by an attempt of community recovery through the second finer pulse, characterised by main taxa turnover, observing an alternative community functional structure. Based on these results and comparing with past volcanic depositions, we observed different chironomid responses according to their particular ecological habits, and we noted possible percolation effects, mainly in coarse tephras, and probably a delayed record of very low abundance taxa. Our results suggest caution in analysing chironomid assemblages within and adjacent to tephra deposition as local volcanic eruption could affect chironomid community with possible consequences on paleoreconstructions.

The addition of metastasis-directed radiotherapy (MDRT) to immunotherapy in patients with advanced urothelial carcinoma (aUC) has shown promising results. We report the real-world data from the ARON-2 study (NCT05290038) on the impact of conventional (CRT) or stereotactic body radiotherapy (SBRT) on the outcome of aUC patients receiving pembrolizumab after platinum-based-chemotherapy. Medical records of 837 patients were reviewed from 60 institutions in 20 countries. Two hundred and sixty-two patients (31%) received radiotherapy (cohort A), of whom 193 (23%) received CRT and 69 (8%) received SBRT. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate (ORR). Univariate and multivariate analyses were used to explore the association of variables of interest with OS and PFS. With a median follow-up of 22.7 months, the median OS was 10.2 months, 6.8 months and 16.0 months in no RT, CRT and SBRT subgroups (p = 0.005), with an 1y-OS rates of 47%, 34% and 61%, respectively (p < 0.001). The 1y-OS rate in the SBRT subgroup were significantly higher for both lower (63%) and upper tract UC (68%), for pure urothelial histology (63%) and variant histologies (58%), and for patients with bone (40%) and lymph-node metastases (61%). Median PFS was 4.8 months, 9.6 months and 5.8 months in the CRT, SBRT and no RT subgroups, respectively (p = 0.060). The 1y-PFS rate was significantly higher (48%) in the SBRT population and was confirmed in all patient subsets. The difference in terms of ORR was in favour of SBRT. Our real-world analysis showed that the use of SBRT/pembrolizumab combination may play a role in a subset of aUC patients to increase disease control and possibly overall survival.

Unsaturated polyester resins (UPR) are widely in composite manufacturing, particularly in the energy, wind, and construction sectors. When these composites sustain damage, defects or cracks, several methodologies are employed to heal and repair them to extend their lifespan while reducing environmental impacts. In this work, the use of vitrimeric UPR (UPRv) as a matrix for carbon fiber composite, was investigated in terms of healing efficiency by mechanical and thermal properties. Flexural and interlaminar shear strength tests revealed healing efficiencies exceeding 40% and 90%, respectively. These results were attributed to the transesterification exchange occurring within the crosslinked networks of UPRv. As described in our previous work, the incorporation of "Covalent Adaptable Networks (CANs)" enables the conversion of commercial thermoset (UPR) into vitrimeric resins, thereby providing reprocessing and healing capabilities. Furthermore, a comparison between pristine and healed composites with Mode I DCB and Mode II ENF tests, confirm how the introduction of vitrimer in composite facilitates the manufacturing of a self‐healing product, with a significant recovery of the original properties. Highlights: Application of a previous synthetized vitrimeric unsaturated polyester resin (UPRv)—fabrication of CF's composites reinforced with UPRv—investigation of the self‐healing property of the developed laminates—potential application as green and sustainable composites.

AbstractLet k be a field, and let Λ be a (not necessarily finite dimensional) k-algebra. Let V be an indecomposable left Λ-module which is finite dimensional over k and such that dimkExtΛ1(V,V)≤1. Assume further that V has a weak universal deformation ring Rw(Λ,V), which is a complete Noetherian commutative local k-algebra with residue field k. We prove in this note, under certain conditions on the Λ-module V, that Rw(Λ,V) is either isomorphic to k, or k[[t]], or to k[[t]]/(tN) for some integer N≥2. [ABSTRACT FROM AUTHOR]

Laccases (EC 1.10.3.2) are multicopper oxidases with the capability to oxidize diverse phenolic and non-phenolic substrates. While the molecular mechanism of their activity towards phenolic substrates is well-established, their reactivity towards non-phenolic substrates, such as polycyclic aromatic hydrocarbons (PAHs), remains unclear. To elucidate the oxidation mechanism of PAHs, particularly the activation mechanism of the sp2 aromatic C–H bond, we conducted a density functional theory investigation on the oxidation of two PAHs (anthracene and benzo[a]pyrene) using an extensive model of the T1 copper catalytic site of the fungal laccase from Trametes versicolor.

The intrinsically disordered polyglutamine-binding protein 1 (PQBP1) has been linked to various cellular processes including transcription, alternative splicing, translation and innate immunity. Mutations in PQBP1 are causative for neurodevelopmental conditions collectively termed as the Renpenning syndrome spectrum. Intriguingly, cells of Renpenning syndrome patients exhibit a reduced innate immune response against human immunodeficiency virus 1 (HIV-1). PQBP1 is responsible for the initiation of a two-step recognition process of HIV-1 reverse-transcribed DNA products, ensuring a type 1 interferon response. Recent investigations revealed that PQBP1 also binds to the p17 protein of avian reovirus (ARV) and is affected by the ORF52 of Kaposi's sarcoma-associated herpesvirus (KSHV), possibly also playing a role in the innate immune response towards these RNA- and DNA-viruses. Moreover, PQBP1-mediated microglia activation in the context of tauopathies has been reported, highlighting the role of PQBP1 in sensing exogenous pathogenic species and innate immune response in the central nervous system. Its unstructured nature, the promiscuous binding of various proteins and its presence in various tissues indicate the versatile roles of PQBP1 in cellular regulation. Here, we systematically review the available data on the structure of PQBP1 and its cellular functions and interactome, as well as possible implications for innate immune responses and neurodegenerative disorders.

A neurofibroma with focal glomus‐like body differentiation is an unusual phenomenon recently encountered in an excision specimen from the right lateral distal forearm of a 26‐year‐old man. Glomus cells are modified smooth muscle cells normally present in glomus‐like bodies but can also be found in glomus tumors (GT) or lesions considered in the spectrum of GT, including myopericytoma, myofibroma, and angiolipoma. Neurofibromas are peripheral nerve sheath tumors derived from the neural crest cells. While both GT and its variants and neurofibroma are thought to be derived from different cell types, there is growing evidence that glomus cells have a neural crest origin. This is based on multiple theories, with some overlapping pathways, including neural crest cell differentiation, Schwann cell reprogramming, VEGF expression, and NF1 gene biallelic inactivation. This report adds to the growing evidence of possible neural crest origin for glomus cells and would help explain finding glomus‐like bodies scattered through a neurofibroma. [ABSTRACT FROM AUTHOR]

This article discusses a case of a 33-year-old male who presented with progressive ascending hypoesthesia and other neurological symptoms. Initially, the symptoms mimicked Neuromyelitis Optica spectrum disorder (NMOSD), but further investigation revealed a longitudinally extensive spinal cord lesion caused by nitrous oxide (N2O) toxicity. The article highlights the importance of considering N2O toxicity as a potential cause of subacute myelopathy, especially in young individuals. It emphasizes the need for a comprehensive medical history, including inquiry about N2O use, and prompt treatment with vitamin B12 supplementation. The article also mentions the increasing trend of N2O-induced subacute combined degeneration of the cord among young adults and the need for guidelines on managing these cases.

Veterinary acupuncture is a complementary and alternative medicine practiced widely in Brazil and is recognized as a specialty by the Federal Council of Veterinary Medicine. However, despite the growing interest of professionals for training and of clients for care, there are no studies on the socioeconomic profile of these veterinary acupuncturists in Brazil. The present survey received 295 (complete) replies, the majority of the respondents were 40 years old or less, female (87%) and were from the southeastern region of Brazil. Furthermore, 57% of respondents were at the beginning of their acupuncture careers with less than 5 years of practice. Most respondents chose to be an acupuncturist for personal satisfaction and perceived effectiveness of acupuncture. Experienced acupuncturists received better financial rewards and were more satisfied with their earnings and valued by their clients. Most respondents believe that acupuncture has scientific evidence through experimental and clinical studies. The socioeconomic profile of veterinary acupuncturists is essential to elaborate future action plans and help improve the quality of veterinary professionals. [ABSTRACT FROM AUTHOR]

Harnessing light for cross-linking of photoresponsive materials has revolutionized the field of 3D printing. A wide variety of techniques leveraging broad-spectrum light shaping have been introduced as a way to achieve fast and high-resolution printing, with applications ranging from simple prototypes to biomimetic engineered tissues for regenerative medicine. Conventional light-based printing techniques use cross-linking of material in a layer-by-layer fashion to produce complex parts. Only recently, new techniques have emerged which deploy multidirection, tomographic, light-sheet or filamented light-based image projections deep into the volume of resin-filled vat for photoinitiation and cross-linking. These Deep Vat printing (DVP) approaches alleviate the need for layer-wise printing and enable unprecedented fabrication speeds (within a few seconds) with high resolution (>10 μm). Here, we elucidate the physics and chemistry of these processes, their commonalities and differences, as well as their emerging applications in biomedical and non-biomedical fields. Importantly, we highlight their limitations, and future scope of research that will improve the scalability and applicability of these DVP techniques in a wide variety of engineering and regenerative medicine applications.

Context. In recent years, a growing number of regularly rotating galaxy discs have been found at z ≥ 4. Such systems provide us with the unique opportunity to study the properties of dark matter (DM) halos at these early epochs, the turbulence within the interstellar medium and the evolution of scaling relations. Aims. Here, we investigate the dynamics of four gas discs in galaxies at z ∼ 4.5 observed with ALMA in the [CII] 158 μm fine-structure line. We aim to derive the structural properties of the gas, stars and DM halos of the galaxies and to study the mechanisms driving the turbulence in high-z discs. Methods. We decomposed the rotation curves into baryonic and DM components within the extent of the [CII] discs, that is, 3 to 5 kpc. Furthermore, we used the gas velocity dispersion profiles as a diagnostic tool in investigating the mechanisms driving the turbulence in the discs. Results. We obtain total stellar, gas and DM masses in the ranges of log(M/M⊙) = 10.3 − 11.0, 9.8 − 11.3, and 11.2 − 13.3, respectively. We find dynamical evidence in all four galaxies for the presence of compact stellar components conceivably, stellar bulges. The turbulence present in the galaxies appears to be primarily driven by stellar feedback, negating the necessity for large-scale gravitational instabilities. Finally, we investigate the position of our galaxies in the context of local scaling relations, in particular the stellar-to-halo mass and Tully–Fisher analogue relations. [ABSTRACT FROM AUTHOR]

Background/Objectives: Burden Syndrome, also known as Caregiver Syndrome, particularly affects those who serve in the role of informal caregiver in the presence of family members with conditions. The ABCX dual model examines the impact on the caregiver of the diagnosis of autism spectrum disorder (ASD) on the family. This model considers the severity of the stressor (A), the additional demands of life stress (aA), the family's internal resources (B), the family's external resources (bB), the family's assessment of the situation (C), coping strategies (cC), and outcome (X). The purpose of the present study is to investigate the relationships between resilience, guilt, and burden of care in caregivers of children with ASD. Methods: Various assessment instruments were used, including the "Caregiver Burden Inventory" to measure burden, the "Brief Resilience Scale" to assess resilience, the "Guilt Sensitivity Questionnaire" to examine guilt sensitivity, and the "DA.L.I.A." to collect information on parent and child characteristics. A total of 80 parents/caregivers participated in the research, including 53 women (Age M = 41.72; SD = 7.8) and 27 men (Age M = 43.35; SD = 6.29). Results: The findings indicate that individuals' resilience to stressful events correlates negatively with burden, a developmental subtype. However, guilt seems not to play a significant role in the overall perception of burden. In contrast, it was found that the use of informal supports is associated with higher levels of guilt and emotional burden, whereas the use of formal supports is correlated with higher emotional burden, but not higher perceptions of guilt. Conclusions: This study provides important information about the support needed by caregivers and suggests how to address emotional burdens to prevent burnout and support families with children with ASD.

Background: Recent studies have suggested using positron emission tomography/computed tomography (PET/CT) with prostate-specific membrane antigen (PSMA)-targeting radiopharmaceuticals for the detection of salivary gland malignancies (SGM), particularly adenoid-cystic carcinoma (ACC). Methods: The authors conducted an extensive review of the scientific literature to examine the potential diagnostic role of PET/CT using PSMA-targeting radiopharmaceuticals in salivary gland malignancies (SGMs) and adenoid cystic carcinoma (ACC). This study included newly diagnosed SGM patients and those with disease recurrence in their imaging evaluation. Results: This updated systematic review included a total of six studies that examined the diagnostic performance of PSMA-targeted PET/CT in ACC. The articles provided evidence of a high detection rate of PSMA-targeting PET/CT in ACC across all clinical contexts examined. SGMs other than ACC exhibited poorer diagnostic performance. Conclusions: PSMA-targeted PET/CT seems promising in detecting ACC lesions; moreover, PSMA appears to be a suitable potential target for radioligand therapy. Prospective multicentric studies are warranted to strengthen the role of PSMA-targeting radiopharmaceuticals in ACC, as both diagnostic and theragnostic agents. [ABSTRACT FROM AUTHOR]

Mild cognitive impairment (MCI) is a significant concern as it is a risk factor for AD progression, and early detection is vital in order to delay dementia onset and enable potential therapeutic interventions. Olfactory impairment is recognized as a predictive biomarker in neurodegenerative processes. The aims of this study were to explore the degree of entorhinal cortical atrophy (ERICA) and the severity of MCI symptoms; to analyze magnetic resonance imaging (MRI) results for the entorhinal cortex, parahippocampal gyrus, peri entorhinal cortex, and the cerebellar tentorium; and to perform a comprehensive neuropsychological and psychophysical assessment. The main results highlighted that in our sample—multidomain amnesic MCI patients with hyposmic symptomatology—we found that ERICA scores were associated with the severity of anxiety symptomatology. One possible hypothesis to explain this observation is that anxiety may contribute to neurodegenerative processes by inducing chronic stress and inflammation. Future research should consider the longitudinal development of neuropsychological scores, anxiety disorders, and brain atrophy to determine their potential predictive value for MCI progression. These findings suggest the importance of psychological factors in MCI progression and the utility of neuropsychological assessment alongside neuroimaging techniques for early detection and follow-up in MCI patients.

Mirror Visual Feedback (MVF)-induced illusion of hand movements produces beneficial effects in patients with chronic pain. However, neurophysiological mechanisms underlying these effects are poorly known. In this preliminary study, we test the novel hypothesis that such an MVF-induced movement illusion may exert its effects by changing the activity in midline cortical areas associated with pain processing. Electrical stimuli with individually fixed intensity were applied to the left hand of healthy adults to produce painful and non-painful sensations during unilateral right-hand movements with such an MVF illusion and right and bilateral hand movements without MVF. During these events, electroencephalographic (EEG) activity was recorded from 64 scalp electrodes. Event-related desynchronization (ERD) of EEG alpha rhythms (8–12 Hz) indexed the neurophysiological oscillatory mechanisms inducing cortical activation. Compared to the painful sensations, the non-painful sensations were specifically characterized by (1) lower alpha ERD estimated in the cortical midline, angular gyrus, and lateral parietal regions during the experimental condition with MVF and (2) higher alpha ERD estimated in the lateral prefrontal and parietal regions during the control conditions without MVF. These preliminary results suggest that the MVF-induced movement illusion may affect nociception and neurophysiological oscillatory mechanisms, reducing the activation in cortical limbic and default mode regions.

The Visceral Sensitivity Index (VSI) represents a significant advancement in the assessment of gastrointestinal-specific anxiety among patients with irritable bowel syndrome (IBS) and chronic inflammatory bowel diseases (IBD)—such as ulcerative colitis and Crohn's disease. However, an Italian version of the instrument is not yet available for the Italian-speaking population. This study utilized a national sample of 500 individuals divided into four groups: (a) patients with Crohn's disease, (b) patients with ulcerative colitis, (c) patients with IBS, and (d) healthy controls (individuals without any diagnoses) to test the validity and reliability of the Italian VSI. Using back-translation methodology to ensure translation fidelity, this research applied a questionnaire and the VSI through an online format to 500 participants. Confirmatory Factor Analysis (CFA) revealed that the Italian VSI had excellent psychometric properties, demonstrating high internal consistency (Cronbach's α = 0.949) and construct validity. The scale proved sensitive in detecting significant differences in visceral sensitivity among groups, highlighting its utility as a clinical and research assessment tool. Specifically, the Italian VSI exhibited a unidimensional factorial structure and maintained a strong correlation with interoceptive awareness, type of disease, and gastrointestinal symptom severity, confirming its role in enhancing the understanding and management of IBD and IBS in Italy.

Quinoa is a facultative halophyte with excellent tolerance to salinity. In this study, the epidermal bladder cell complex (EBCc) of quinoa leaves was studied to determine their cellular characteristics and involvement in salt tolerance. We used light microscopy, confocal RAMAN microscopy, confocal fluorescence microscopy, transmission electron microscopy, and environmental scanning electron microscopy complemented by energy dispersive X-ray analysis. Ionic content was quantified with flame atomic absorption spectroscopy and with flame emission photometry. Results show that: (i) the number of EBCcs remains constant but their density and area vary with leaf age; (ii) stalk cells store lipids and exhibit thick walls, bladder cells present carotenes in small vesicles, oxalate crystals in vacuoles and lignin in their walls and both stalk and bladder cells have cuticles that differ in wax and cutin content; (iii) chloroplasts containing starch can be found on both stalk and bladder cells, and the latter also presents grana; (iv) plasmodesmata are observed between the stalk cell and the bladder cell, and between the epidermal cell and the stalk cell, and ectodesmata-like structures are observed on the bladder cell. Under high salinity conditions, (v) there is a clear tendency to accumulate greater amounts of K+ with respect to Na+ in the bladder cell; (vi) stalk cells accumulate similar amounts of K+ and Na+; (vii) Na+ accumulates mainly in the medullary parenchyma of the stem. These results add knowledge about the structure, content, and role of EBCc under salt stress, and surprisingly present the parenchyma of the stem as the main area of Na+ accumulation.

In this paper, the new dynamic geophysical and geochemical MUltiparametric DAtabase (MUDA) is presented. MUDA is a new infrastructure of the National Institute of Geophysics and Volcanology (INGV), published on-line in December 2023, with the aim of archiving and disseminating multiparametric data collected by multidisciplinary monitoring networks. MUDA is a MySQL relational database with a web interface developed in php, aimed at investigating in quasi real time possible correlations between seismic phenomena and variations in endogenous and environmental parameters. At present, MUDA collects data from different types of sensors such as hydrogeochemical probes for physical-chemical parameters in waters, meteorological stations, detectors of air Radon concentration, diffusive flux of carbon dioxide (CO2) and seismometers belonging both to the National Seismic Network of INGV and to temporary networks installed in the framework of multidisciplinary research projects. MUDA daily publishes data updated to the previous day and offers the chance to view and download multiparametric time series selected for different time periods. The resultant dataset provides broad perspectives in the framework of future high frequency and continuous multiparametric monitorings as a starting point to identify possible seismic precursors for short-term earthquake forecasting. MUDA is now quoted with the Digital Object Identifier https://doi.org/10.13127/muda (Massa et al., 2023). [ABSTRACT FROM AUTHOR]

The utilization of graphic novels in the realm of clinical medicine is an infrequent occurrence. However, there is a burgeoning interest in their application across a spectrum of pathological conditions with the ultimate aim of enhancing patient care. This study is a prospective pilot designed to assess the influence of graphic novels on the stress levels and behavioral responses of patients diagnosed with pancreatic lesions and who are to undergo endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). Patients exhibiting radiological and clinical pancreatic lesions needing biopsy will be evaluated consecutively. The inclusion criteria encompass the presence of a solid pancreatic mass or a partially solid mass in the event of a cystic component. The exclusion criteria include patients with cognitive impairments, those currently on benzodiazepines or other psychotropic medications, and those with a prior diagnosis of cancer. The authors have developed a comic panel comprising a sequence of six vibrant vignettes, which delineate the standard procedure of EUS-FNB to the patient. Following hospital admission, patients whomeet the enrolment criteria and consent to participate in the studywill be randomly assigned to either the test or the control group. A graphic novel will be distributed to all patients in the test group, who will have the opportunity to peruse it while awaiting the procedure. Subsequent to the EUS-FNB, all enrolled patients will complete the Beck Anxiety Inventory (BAI) and amodified version of the Depression Anxiety Stress Scales-21 (termed mDASS-21 or mASS-14). The BAI, a 21-itemself-report inventory, is employed to gauge the severity of anxiety in adults. The other questionnaire is a modified rendition of the DASS-21, which originally comprised 21 items segregated into three subscales (anxiety, stress, and depression) with seven items each. The anxiety subscale measures physiological arousal, situational anxiety, and the subjective experience of the effects of anxiety, while the stress subscale assesses chronic non-specific arousal, difficulty relaxing, nervous tension, irritability, agitation, and impatience.

The availability of microbial biobanks for the storage of individual gut microbiota members or their derived and artificially assembled consortia has become fundamental for in vitro investigation of the molecular mechanisms behind microbe–microbe and/or microbe–host interactions. However, to preserve bacterial viability, adequate storage and processing technologies are required. In this study, the effects on cell viability of seven different combinations of cryoprotective agents were evaluated by flow cytometry for 53 bacterial species representing key members of the human gut microbiota after one and 3 months of cryopreservation at −80°C. The obtained results highlighted that no universal cryoprotectant was identified capable of guaranteeing effective recovery of intact cells after cryopreservation for all tested bacteria. However, the presence of inulin or skimmed milk provided high levels of viability protection during cryoexposure. These results were further corroborated by cryopreserving 10 artificial gut microbiota produced through in vitro continuous fermentation system technology. Indeed, in this case, the inclusion of inulin or skimmed milk resulted in a high recovery of viable cells, while also allowing consistent and reliable preservation of the artificial gut microbiota biodiversity. Overall, these results suggest that, although the efficacy of various cryoprotective agents is species‐specific, some cryoprotectants based on glycerol and the addition of inulin or skimmed milk are preferable to retain viability and biodiversity for both single bacterial species and artificial gut microbiota.

The role of fibroblast activation protein inhibitor (FAPI) positron emission tomography/computed tomography (PET/CT) is emerging for the assessment of non-oncological diseases, such as inflammatory and infectious diseases, even if the evidence in the literature is still in its initial phases. We conducted a systematic search of Scopus, PubMed/MEDLINE, Embase, and Cochrane library databases for studies published before 31 December 2023 reporting infectious and inflammatory disease imaging with FAPI PET/CT. We included twenty-one studies for a total of 1046 patients. The most frequent disease studied was lung interstitial disease, investigated in six studies for a total of 200 patients, followed by bone and joint diseases in two studies and 185 patients, IgG4-related disease in 53 patients, and Crohn's disease in 30 patients. Despite the heterogeneity of studies in terms of study design and technical features, FAPI PET/CT showed a high detection rate and diagnostic role. Moreover, when compared with 2-[18F]FDG PET/CT (n = 7 studies), FAPI PET/CT seems to have better diagnostic performances. The presence of chronic inflammation and tissue remodeling, typical of immune-mediated inflammatory conditions, may be the underlying mechanism of FAPI uptake. [ABSTRACT FROM AUTHOR]

Non-destructive monitoring methods are crucial for the management and maintenance of assets, which include reinforced concrete (RC) structures. Steel reinforcing bar (rebar) corrosion is one of the main causes of deterioration of engineered reinforced structures as it decreases their strength and serviceability. The purpose of this study was to use nondestructive geophysical techniques to detect and monitor rebar corrosion phenomena. To achieve this, several laboratory tests were performed on RC samples partially immersed in water containing a 5% of sodium chloride (NaCl) solution. Moreover, an accelerated corrosion phenomenon was produced by supplying direct current power along the rebar. Ground-penetrating radar measurements were performed on the concrete surface using 2.0 GHz centre frequency antennas, self-potential acquisitions, and electrical resistivity tomography. Even though each technique provided specific information, a data integration approach, simultaneously using different sensors, would further improve the overall quality of the diagnosis. The data set collected was used for an integrated detection approach, effective in observing the evolution of the corrosion process along the reinforcement bar. Through these laboratory results, a multisensor approach and an integrated observation proved useful for observing the evolution of corrosion phenomenon in reinforcement bars, as a consequence of the steel rebar corrosion.

Background: Ductal carcinoma in situ (DCIS) is often reclassified as invasive cancer in the final pathology report of the surgical specimen. It is of significant clinical relevance to acknowledge the possibility of underestimating invasive disease when utilizing preoperative biopsies for a DCIS diagnosis. In cases where such histologic upgrades occur, it is imperative to consider them in the preoperative planning process, including the potential inclusion of sentinel lymph node biopsy due to the risk of axillary lymph node metastasis. Purpose: To assess the capability of breast multiparametric magnetic resonance imaging (MP-MRI) in differentiating between pure DCIS and microinvasive carcinoma (MIC). Material and Methods: Between January 2018 and November 2022, this retrospective study enrolled patients with biopsy-proven DCIS who had undergone preoperative breast MP-MRI. We assessed various MP-MRI features, including size, morphology, margins, internal enhancement pattern, extent of disease, presence of peritumoral edema, time-intensity curve value, diffusion restriction, and ADC value. Subsequently, a logistic regression analysis was conducted to explore the association of these features with the pathological outcome. Results: Of 129 patients with biopsy-proven DCIS, 36 had foci of micro-infiltration on surgical specimens and eight were diagnosed with invasive ductal carcinoma (IDC). The presence of micro-infiltration foci was significantly associated with several MP-MRI features, including tumor size (P <0.001), clustered ring enhancement (P <0.001), segmental distribution (P <0.001), diffusion restriction (P = 0.005), and ADC values <1.3 × 10−3 mm2/s (P = 0.004). Conclusion: Breast MP-MRI has the potential to predict the presence of micro-infiltration foci in biopsy-proven DCIS and may serve as a valuable tool for guiding therapeutic planning.

Simple Summary: Despite the promising evidence of the Royal Marsden Hospital (RMH) score as a readily available prognostic biomarker in patients with cancer, the wide scale implementation in clinical practice as well as the true benefit in clinical decision-making is lacking. Therefore, we systematically reviewed the available evidence on the association between the RMH score and prognosis in patients with cancer. This comprehensive meta-analysis, encompassing over a hundred thousand patients, revealed a negative association between a higher RMH score and survival in cancer patients. The available evidence demonstrates that the RMH score is not only a selective biomarker for patients enrolled in clinical trials, but also a useful prognostic biomarker in a real-world setting. Future research should aim to validate and refine this score, ensuring its optimal application in clinical practice and decision-making. Background: Cancer remains a leading cause of death globally, necessitating the identification of prognostic biomarkers to guide treatment decisions. The Royal Marsden Hospital (RMH) score, based on readily available blood tests and clinical features, has emerged as a prognostic tool, although its performance across variable clinical scenarios is not thoroughly delineated. Therefore, we aimed to systematically assess the association between RMH score and survival in cancer patients. Methods: We conducted a systematic literature search across Pubmed, Scopus, and Web of Science databases for studies published up to 15 February 2024. We performed a meta-analysis with the generic inverse variance method with a random-effects model and reported hazard ratios (HR) with 95% confidence intervals (CI). Results: Nineteen studies encompassing 127,230 patients were included. A higher RMH score was significantly associated with worse overall survival (OS) (HR: 2.09, 95% CI: 1.87–2.33, p < 0.001) and progression-free survival (PFS) (HR: 1.80, 95% CI: 1.48–2.18, p < 0.001). This association was consistent across various subgroups, including study population (clinical trial vs. real-world cohort), geographic region, and tumor type. Conclusion: This meta-analysis, including over a hundred thousand patients, demonstrates a negative association between a higher RMH score and survival in cancer patients. The RMH score holds promise as a readily available prognostic tool across diverse cancer types and clinical settings. Future research should focus on validating and refining this score to aid clinical decision-making. [ABSTRACT FROM AUTHOR]

Work-integrated learning (WIL) environments are designed to assist students in consolidating their acquired knowledge and skills, apply them to real-world settings and develop a professional identity. Promoting industry engagement and assisting students make links between what they are learning and how it applies to professional practice is one of our key roles as educators. Studies in the relationship between well-being and learning confirm the need for tertiary educators to consider how personal values, health and behaviours radically interact with skills development in the designing and implementation of our teaching and learning programs. It is an imperative we keep abreast of contemporary media practices, but also build effective networks with community and industry and generate partnerships to assist students as they navigate their way through the academy in an increasingly complex world. Informed by studio and project-based learning and experiential methodologies that facilitate student centred approaches with high levels of self-directed learning we discuss our respective pedagogical approaches to the Yagan Square digital tower project, Perth Australia, to promote student engagement with their own communities and how to work with an external organisation who also act as a client and mentors to students .

Simple Summary: Individuals with metabolic syndrome exhibit simultaneously pro-thrombotic and a pro-inflammatory conditions which more probably can lead to cardiovascular disease progression, type 2 diabetes mellitus, and some types of cancer. The present scoping review is aimed at highlighting any relations between cancer risk, inflammation, and metabolic syndrome. A total of 20 manuscripts were identified and, among them, we identified some associations with breast cancer, colorectal cancer, esophageal adenocarcinoma, hepatocellular carcinoma (HCC), and cancer in general. Therefore, it could be deducted that cancer and its related progression may also depend on a latent chronic inflammatory condition associated with other concomitant conditions, including type 2 diabetes mellitus, metabolic syndrome, and obesity. Therefore, prevention may potentially help individuals to protect themselves from cancer.

We evaluated GaAs nanoparticle-concentrations in the air and on skin and surfaces in a research facility that produces thin films, and to monitored As in the urine of exposed worker. The survey was over a working week using a multi-level approach. Airborne personal monitoring was implemented using a miniature diffusion size classifier (DiSCMini) and IOM sampler. Environmental monitoring was conducted using the SKC Sioutas Cascade Impactor to evaluate dimensions and nature of particles collected. Surfaces contamination were assessed analyzing As and Ga in ghost wipes. Skin contamination was monitored using tape strips. As and Ga were analyzed in urines collected every day at the beginning and end of the shift. The greatest airborne exposure occurred during the cutting operations of the GaAs Sample (88883 np/cm3). The highest levels of contamination were found inside the hood (As max = 1418 ng/cm2) and on the laboratory floor (As max = 251 ng/cm2). The average concentration on the worker's skin at the end of the work shift (3.36 ng/cm2) was more than 14 times higher than before the start of the shift. In weekly urinary biomonitoring an average As concentration of 19.5 µg/L, which was above the Società Italiana Valori di Riferimento (SIVR) reference limit for the non-occupational population (2.0 – 15 µg/L), but below the ACGIH limit (30 µg/L). Overall, airborne monitoring, surface sampling, skin sampling, and biomonitoring of worker confirmed the exposure to As of workers. Systematic cleaning operations, hood implementation and correct PPE management are needed to improve worker protection. [ABSTRACT FROM AUTHOR]

Simple Summary: Richter transformation (RT) is characterized by the transformation of CCL in the aggressive lymphoma variant with a significant worsening in prognosis. Initial reports about a substantial impact of 2-deoxy-2-[18F]-fluoro-D-glucose positron emission tomography/computed tomography (2-[18F]FDG PET/CT) in predicting RT are available in the literature. Using data from 15 published studies, including 1593 CLL patients, we demonstrated that 2-[18F]FDG uptake expressed as the maximum standardized uptake value (SUVmax) has a high negative predictive value. Richter transformation is a rare phenomenon characterized by the transformation of cell chronic lymphocytic leukemia (CLL) into a more aggressive lymphoma variant. The early identification of CLLs with a high risk of RT is fundamental. In this field, 2-deoxy-2-[18F]-fluoro-D-glucose positron emission tomography/computed tomography (2-[18F]FDG PET/CT) has been shown to be a non-invasive and promising tool, but apparently, unclear data seem to be present in the literature. This systematic review and bivariate meta-analysis aimed to investigate the diagnostic performance of 2-[18F]FDG PET/CT and its parameters in predicting RT. Between 2006 and 2024, 15 studies were published on this topic, including 1593 CLL patients. Among semiquantitative variables, SUVmax was the most investigated, and the best threshold derived for detecting RT was five. With this cut-off value, a pooled sensitivity of 86.8% (95% CI: 78.5–93.3), a pooled specificity of 48.1% (95% CI: 27–69.9), a pooled negative predictive value of 90.5% (95% CI: 88.4–92.4), a pooled negative likelihood ratio of 0.35 (95% CI: 0.17–0.70), a pooled positive likelihood ratio of 1.8 (95% CI: 1.3–2.4), and a pooled diagnostic odds ratio of 6.7 (3.5–12.5) were obtained. With a higher cut-off (SUVmax = 10), the specificity increased while the sensitivity reduced. The other metabolic features, like metabolic tumor volume, total lesion glycolysis, and radiomic features, were only marginally investigated with controversial evidence. [ABSTRACT FROM AUTHOR]

Background: Endovascular thrombectomy (EVT) is a treatment option in patients with a cerebral venous thrombosis (CVT) who deteriorate despite anticoagulant treatment. Assessment of thrombus composition in CVT may provide insights into the pathophysiology of the disease and suggest new therapeutic strategies. Case report: A 47-year-old woman (smoking habit and estradiol/progesterone-releasing intra-uterine device) diagnosed with massive CVT underwent EVT (complete recanalization via aspiration catheter and stentriever) due to acute-onset left-sided weakness and dysarthria despite 72 h of full-dose subcutaneous low-molecular heparin. Two main reddish clots (maximum diameter 15 mm) were retrieved. Microscopic assessment showed an erythrocyte-rich thrombus (83.9% of entire thrombus surface) with layers of platelets/fibrin (lines of Zahn: 13.9% fibrin and 38.5% platelet [CD61+]). The immunological profile was dominated by neutrophils (30% MPO+), with neutrophil extracellular traps (NETs) in 1.9% of thrombus surface. T- (CD3+), B-lymphocytes (CD20+), and monocytes/macrophages (CD68+) were rather rare (2.2%, 0.7%, and 2.0% respectively). We found no evidence (0.0%) of hemosiderin and endothelial cells (CD34+). Full clinical recovery occurred prior to discharge. Conclusion: This is the first case report of a CVT with histologic assessment of the thrombus retrieved via EVT. Evaluating thrombi in CVT can provide key insights into disease pathophysiology and guide treatment advancements. [ABSTRACT FROM AUTHOR]

The article explores a modified technique called submandibular degloving for submandibular sialoadenectomy, a surgical procedure to remove the submandibular gland. The technique aims to minimize complications by preserving the fascia, facial vessels, and nerves. The study presents the outcomes of 35 cases using this technique, demonstrating no recurrences of neoplastic lesions and a low rate of nerve injuries. While the technique shows promise, the study acknowledges limitations such as being a single-center case series and lacking a control group, highlighting the need for further research to validate the findings.

Introduction/Background: Pediatric diffuse midline gliomas are predominantly localized within the brainstem, pons, or are bi-thalamic, while in adolescents and adults, they predominantly arise unilaterally in the thalamus or spinal cord. Epidemiological data remain scarce for this recently described entity. They represent 10-15% of all pediatric brain tumors and 75% of all pediatric brainstem tumors. Case presentation: Herein we report a case of Diffuse Midline Glioma in a 10-yearold male pediatric patient, with an unusual location in the spinal cord, presenting with atypical clinical features. Histopathological and immunohistochemical analysis confirmed the diagnosis and the presence of K27M (lysine to methionine at codon 27) mutations in the histone 3 gene. Conclusions: Early and differential diagnosis of atypical spinal cord tumors is crucial to avoid dismal consequences for the patient and provide them with a better quality of life. Highlighting rare cases with fatal outcomes is essential for emphasizing the importance of understanding this pathological entity within the medical community. [ABSTRACT FROM AUTHOR]
