Abstract
Background
Intrahepatic cholangiocarcinoma (iCCA) is a highly aggressive cancer that is challenging to diagnose at an early stage. Despite recent advances in combination chemotherapy, drug resistance limits the therapeutic value of this regimen. iCCA reportedly harbors high HMGA1 expression and pathway alterations, especially hyperactivation of the CCND1/CDK4/CDK6 and PI3K signaling pathway. In this study, we explored the potential of targeting CDK4/6 and PI3K inhibition to treat iCCA.

Methods
The significance of HMGA1 in iCCA was investigated with in vitro/vivo experiments. Western blot, qPCR, dual-luciferase reporter and immunofluorescence assays were performed to examine the mechanism of HMGA1 induced CCND1 expression. CCK-8, western blot, transwell, 3D sphere formation and colony formation assays were conducted to predict the potential role of CDK4/6 inhibitors PI3K/mTOR inhibitors in iCCA treatment. Xenograft mouse models were also used to determine the efficacy of combination treatment strategies related to HMGA1 in iCCA.

Results
HMGA1 promoted the proliferation, epithelial-mesenchymaltransition (EMT), metastasis and stemness of iCCA. In vitro studies showed that HMGA1 induced CCND1 expression via promoting CCND1 transcription and activating the PI3K signaling pathway. Palbociclib(CDK4/6 inhibitor) could suppress iCCA proliferation, migration and invasion, especially during the first 3 days. Although there was more stable attenuation of growth in the HIBEpic model, we observed substantial outgrowth in each hepatobiliary cancer cell model. PF-04691502(PI3K/mTOR inhibitor) exhibited similar effects to palbociclib. Compared with monotherapy, the combination retained effective inhibition for iCCA through the more potent and steady inhibition of CCND1, CDK4/6 and PI3K pathway. Furthermore, more significant inhibition of the common downstream signaling pathways is observed with the combination compared to monotherapy.

Conclusions
Our study reveals the potential therapeutic role of dual inhibition of CDK4/6 and PI3K/mTOR pathways in iCCA, and proposes a new paradigm for the clinical treatment of iCCA.
Imaging biomarkers for clinical applications in neuro-oncology: current status and future perspectives
Authors: Chiu Fang-Ying , Yen Yun 
Published: March 2023

AbstractBiomarker discovery and development are popular for detecting the subtle diseases. However, biomarkers are needed to be validated and approved, and even fewer are ever used clinically. Imaging biomarkers have a crucial role in the treatment of cancer patients because they provide objective information on tumor biology, the tumor's habitat, and the tumor’s signature in the environment. Tumor changes in response to an intervention complement molecular and genomic translational diagnosis as well as quantitative information. Neuro-oncology has become more prominent in diagnostics and targeted therapies. The classification of tumors has been actively updated, and drug discovery, and delivery in nanoimmunotherapies are advancing in the field of target therapy research. It is important that biomarkers and diagnostic implements be developed and used to assess the prognosis or late effects of long-term survivors. An improved realization of cancer biology has transformed its management with an increasing emphasis on a personalized approach in precision medicine. In the first part, we discuss the biomarker categories in relation to the courses of a disease and specific clinical contexts, including that patients and specimens should both directly reflect the target population and intended use. In the second part, we present the CT perfusion approach that provides quantitative and qualitative data that has been successfully applied to the clinical diagnosis, treatment and application. Furthermore, the novel and promising multiparametric MR imageing approach will provide deeper insights regarding the tumor microenvironment in the immune response. Additionally, we briefly remark new tactics based on MRI and PET for converging on imaging biomarkers combined with applications of bioinformatics in artificial intelligence. In the third part, we briefly address new approaches based on theranostics in precision medicine. These sophisticated techniques merge achievable standardizations into an applicatory apparatus for primarily a diagnostic implementation and tracking radioactive drugs to identify and to deliver therapies in an individualized medicine paradigm. In this article, we describe the critical principles for imaging biomarker characterization and discuss the current status of CT, MRI and PET in finiding imaging biomarkers of early disease.

Published: March 2023

AbstractChloroethenes are widely used as solvent in the metal industry and the dry cleaning industry, but their spillage into soil and groundwater due to improper handling has negatively impacted human health. Bioremediation using microorganisms is one of the technologies to clean up soil and groundwater contaminated with chloroethenes. In this study, we examined the bioremediation of chloroethene-contaminated soil using wine pomace extract (WPE). WPE is a liquid containing seven major carboxylic acids and other substances extracted from grape pomace produced in winemaking. WPE clearly promoted the anaerobic bioremediation of chloroethenes. In the tetrachloroethene (PCE) degradation test that used fractions derived from WPE, the water-eluted fraction containing l-lactic acid, l-tartaric acid, and others promoted the dechlorination of PCE, whereas the methanol-eluted fraction containing mainly syringic acid did not. In another PCE degradation test that used l-lactic acid, l-tartaric acid, and syringic acid test solutions, l-lactic acid and l-tartaric acid enhanced the dechlorination of PCE, but syringic acid did not. The results suggest that l-lactic acid and l-tartaric acid in WPE function as hydrogen donors in the anaerobic microbial degradation of chloroethene. This technology realizes environmental remediation through the effective use of food by-products.

Published: March 2023

Abstract
Background
The specific binding ratio (SBR) of 123I-FP-CIT in the putamen is widely used to support the interpretation of dopamine transporter (DAT) SPECT. Automatic methods for computation of the putamen SBR often include stereotactical normalization of the individual DAT-SPECT image to an anatomical standard space. This study compared using a single 123I-FP-CIT template image as target for stereotactical normalization versus multiple templates representative of normal and different levels of Parkinson-typical reduction of striatal 123I-FP-CIT uptake.

Methods
1702 clinical 123I-FP-CIT SPECT images were stereotactically normalized (affine) to the anatomical space of the Montreal Neurological Institute (MNI) with SPM12 either using a single custom-made 123I-FP-CIT template representative of normal striatal uptake or using eight different templates representative of normal and different levels of Parkinson-typical reduction of striatal FP-CIT uptake with and without attenuation and scatter correction. In the latter case, SPM finds the linear combination of the multiple templates that best matches the patient’s image. The putamen SBR was obtained using hottest voxels analysis in large unilateral regions-of-interest predefined in MNI space. The histogram of the putamen SBR in the whole sample was fitted by the sum of two Gaussians. The power to differentiate between reduced and normal SBR was estimated by the effect size of the distance between the two Gaussians computed as the differences between their mean values scaled to their pooled standard deviation.

Results
The effect size of the distance between the two Gaussians was 3.83 with the single template versus 3.96 with multiple templates for stereotactical normalization.

Conclusions
Multiple templates representative of normal and different levels of Parkinson-typical reduction for stereotactical normalization of DAT-SPECT might provide improved separation between normal and reduced putamen SBR that could result in slightly improved power for the detection of nigrostriatal degeneration.
Radiation-induced fibrosarcoma after breast-conserving therapy for breast cancer: a case report and literature review
Authors: Hoshina Hideko , Kubouchi Kouichi , Tsutsumi Yutaka , Takei Hiroyuki 
Published: March 2023

Abstract
Background
Radiation-induced sarcoma (RIS) has a 10-year incidence of 0.2–0.27% and a poor prognosis, although the radiation should need for breast-conserving surgery. In particular, radiation-induced fibrosarcoma has been rarer, and its incidence is 2.6–3.7% of RIS.

Case presentation
A 43-year-old woman with pT1N1M0 breast cancer underwent breast-conserving surgery, chemotherapy, radiation therapy 8 years ago, and continued hormonal therapy. She complained of a hard unprotruded mass palpated in her right upper outer quadrant of breast. Although we suspected local recurrence, core needle biopsy revealed atypical spindled tumor cells without mammary or epithelial markers. A diagnosis of fibrosarcoma was made via tumorectomy. She underwent additional enlarged surgery.

Conclusions
We report a rare case of fibrosarcoma in breast after breast-conserving surgery and radiation therapy. Fibrosarcoma after radiation therapy for breast cancer has been reported in 30 cases, including the present case. The dead and alive cases were not significantly different in terms of age, primary breast cancer, radiation dose, and following months. Patients with breast masses after radiation therapy should be suspected local recurrence and RIS.
Postoperative choroidal vascularity index after the management of macula-off rhegmatogenous retinal detachment
Authors: Quiroz-Reyes Miguel A. , Quiroz-Gonzalez Erick A. , Quiroz-Gonzalez Miguel A. , Lima-Gomez Virgilio 
Published: March 2023

Abstract
Background
Rhegmatogenous retinal detachment (RRD) is a vision-threatening condition that can be treated with various surgical approaches. The role of scleral buckling remains controversial because of its potential long-term deleterious effects on choroidal vascular perfusion and the limited knowledge of this entity.

Methods
A total of 135 eyes were retrospectively selected, including 115 with surgically resolved RRD and 20 healthy control eyes. Of the surgically treated eyes, 64 underwent vitrectomy alone, while 51 underwent scleral buckling combined with vitrectomy. Best-corrected visual acuity (BCVA) was evaluated along with the choroidal vascularity index (CVI) as a metric for the state of the choroidal vasculature. BCVA was compared before and after surgery, and the postoperative BCVA was analyzed with the CVI using correlation and multivariate regression analyses.

Results
The preoperative BCVA of the RRD eyes was significantly worse than that of the control eyes, and significantly improved after surgery. However, the long-term postsurgical BCVA was still inferior to that of the control eyes. No significant differences in visual function were found between the two surgical groups. The average CVI was 57.35% in the control eyes, 63.76% in the eyes that underwent vitrectomy, and 53.37% in buckled eyes. The differences in CVI were significant among the three groups. Among the surgical patients, negative Pearson’s correlations were found between CVI and postoperative BCVA (expressed in logMAR). A multivariate linear regression model containing four parameters revealed that CVI was the only variable with a significant influence on postoperative BCVA, while the length of time with a detached macula did not have an effect.

Conclusions
RRD surgery drastically restored vision, but the effect of RRD lingered, as postsurgical visual acuity remained inferior to that of the control eyes. The CVI varied between the treatment groups, likely due to both disease pathology and the impact of the surgery. The correlation between CVI and BCVA indicates the important role that the choroidal vasculature plays in visual function.

Abstract
Background
Autism spectrum disorder (ASD) is a common communication disorder, with an incidence rate of 3%. In most cases, clinicians can diagnose ASD in a single outpatient visit. However, in the case of ASD patients without intellectual disability, clinicians are sometimes unaware for a prolonged period that a patient has ASD. In such cases, delayed diagnosis can lead to serious complications.

Case presentation
An 18-year-old boy had repeated severe complications of peritoneal dialysis. At the age of 9, the patient presented with proteinuria, and 5 years later, he developed end-stage kidney disease. Percutaneous renal biopsy and the clinical symptoms revealed focal segmental glomerulosclerosis with Charcot-Marie-Tooth disease due to a gene mutation in INF2. Peritoneal dialysis was initiated at the age of 14, but led to many related complications, including peritonitis, hypertensive retinopathy and encephalopathy, and acute heart failure. Initially, we were unaware of his developmental characteristics and autism spectrum disorder without intellectual disability, but through lengthy observations by various healthcare professionals, his unique characteristics were noticed. Because the patient often displayed a discrepancy between behavior and speech, we cautiously studied his thoughts and behaviors, and developed a special approach to ensure safe peritoneal dialysis.

Conclusions
When many peritoneal dialysis-related complications occur in a patient with normal intelligence quotient, autism spectrum disorder should be considered as a possible cause.

AbstractThousands of people have died of COVID-19 in El Salvador. However, little is known about the mental health of those who are mourning the loss of a loved one to COVID-19. Therefore, the objective of this study was to examine the dysfunctional grief associated with COVID-19 death among Salvadoran adults. A sample of 435 Salvadorans (M = 29 years; SD = 8.75) who lost a family member or loved one to COVID-19 completed a digital survey using the Google Forms platform, during April 2 and 28, 2022. The results revealed that 35.1% reported clinically elevated symptoms of dysfunctional grief and among those mourners, and 25.1% also exhibited clinical levels of coronavirus anxiety. A binary logistic regression revealed that predictor variables such as COVID-19 anxiety (p = .003), depression (p = .021), and COVID-19 obsession (p = .032) were significant (χ2 = 84.31; Nagelkerke R2 = .242) and predict a 24.2% chance of dysfunctional bereavement.

AbstractBackgroundIn the last decades, pediatric patient engagement has received growing attention and its importance is increasingly acknowledged. Pediatric patient engagement in health care can be defined as the involvement of children and adolescents in the decision-making of daily clinical care, research and intervention development. Although more attention is paid to pediatric patient engagement, a comprehensive overview of the activities that have been done regarding pediatric patient engagement and the changes over time is lacking. Therefore, the aim of this study is to provide an overview of the literature about pediatric patient engagement.MethodsThe methodological framework of Arksey & O’Malley was used to conduct this scoping review. The bibliographic databases Medline, Embase, and PsycINFO were searched for eligible articles. All retrieved articles were screened by at least two researchers in two steps. Articles were included if they focused on pediatric patient engagement, were carried out in the context of clinical care in pediatrics, and were published as full text original article in English or Dutch. Data (year of publication, country in which the study was conducted, disease group of the participants, setting of pediatric patient engagement, used methods, and age of participants) were extracted, synthesized, and tabulated.ResultsA total of 288 articles out of the 10,714 initial hits met the inclusion criteria. Over the years, there has been an increase in the number of studies that engage pediatric patients. Pediatric patients, especially patients with multiple conditions or oncology patients, were most involved in studies in the United States, United Kingdom, and Canada. Pediatric patients were most often asked to express their views on questions from daily clinical care and the individual interview was the most used method. In general, the extent to which pediatric patients are engaged in health care increases with age.DiscussionThis scoping review shows that there is an increasing interest in pediatric patient engagement. However, lack of uniformity about the definition of pediatric patient engagement and clear information for clinicians hinders engagement. This overview can inform clinicians and researchers about the different ways in which pediatric patient engagement can be shaped and can guide them to engage pediatric patients meaningfully in their projects.

Authors: Abokrysha Noha T. , Taha Noha , Shamloul Reham , Elsayed Samar , Osama Wesam , Hatem Ghada 
Published: March 2023

Abstract
Background
Epilepsy is the third chronic brain illness worldwide. About a third of the epileptic patients will be drug resistant. Early identification of these patients is critical for appropriate treatment selection and prevention of the devastating consequences of recurrent seizures. The objective of this study aims to detect clinical, electrophysiological, and radiological predictors for drug-resistant epilepsy patients.

Results
One hundred fifty-five patients were included in this study, divided into a well-controlled epilepsy group (103 patients) and a drug-resistant group (52 patients). Both groups were compared regarding clinical, electrophysiological, and neuro-radiological data. Younger age at onset, history of delayed milestones, history of perinatal insult (especially hypoxia), mental retardation, neurological deficits, depression, status epilepticus (SE), complex febrile seizures, focal seizure to bilateral tonic–clonic convulsion as well as multiple seizures and high seizure frequency (daily) at onset, poor response to first anti-seizure drug (ASD), structural and metabolic etiology, abnormal brain imaging, and slow background and multifocal epileptiform discharges in EEG were significant risk factors for the development of drug-resistant epilepsy.

Conclusion
MRI abnormalities are the most significant predictor for drug-resistant epilepsy. Drug-resistant epilepsy is associated with clinical, electrophysiological, and radiological risk factors that can be used to diagnose drug-resistant patients early and choose the best treatment option and time.
Safety and effectiveness of bycross rotational atherectomy and aspiration device: a prospective, multi-center pre-market approval study
Authors: Tessarek Jörg , Kolvenbach Ralf 
Published: March 2023

Abstract
Purpose
To demonstrate safety and effectiveness of the novel ByCross® atherectomy system for treatment of complex femorodistal > 80% arterial stenosis.

Materials and Methods
From September 2018 until April 2019 39 patients with 41 femorodistal lesions including the femoropopliteal and distal popliteal segments were treated in a prospective, nonrandomized pre-market approval study with 6 months follow up using the ByCross® atherectomy device (ClinicalTrials.gov identifier NCT03724279). Adjunctive treatment with balloon dilatation or stenting was allowed by the protocol. Mean patient age was 72 years with 62% male. The average lesions length was 125 ± 118 mm (30 and 450 mm) with an average reference vessel diameter of 5.2 ± 0.85 mm and a mean stenosis of 96.4 ± 6.2% based on CT or MR angiography measurements. The primary performance endpoint was defined as acute procedural success with angiographically determined residual stenosis of ≤ 50% and of ≤ 30% after atherectomy or adjunctive treatment. The primary safety endpoint was the major adverse event (MAE) rate through 30 days. Secondary endpoints were stenosis of the target lesions measured by duplex ultrasound (DUS) and the ankle-brachial pressure index (ABPI) at discharge, 30 and 180 days as well as any major adverse event (MAE) through 6 months.

Results
The acute procedural success was achieved in 39/41 (95.12%) lesions, partially without wire guidance (11/41 (26.82%)). No embolic protection was used, and adjunctive angioplasty and stenting was performed in 40/41 (97.56%) and 12/41 (29.26%) lesions, respectively without device related MAE’s at 30 days. Mean level of stenosis was 5.7% at discharge and 21.7% at 6 months FU measured by DUS. Mean ABPI was 0.8, 1.0 and 0.8 at baseline, discharge, and 6 months FU respectively.

Conclusions
Based on the high technical success rate and the low rates of MAE`s through six months, the BYCROSS® Atherectomy System has shown to be safe and effective for the crossing and atherectomy of complex lower-extremity arterial occlusions.
