For nearly a decade, sorafenib has served as a first-line chemotherapeutic drug for the treatment of hepatocellular carcinoma (HCC), but it displays only limited efficacy against advanced drug-resistant HCC. Regorafenib, the first second-line drug approved for treatment after sorafenib failure, can reverse resistance to sorafenib. We used bioinformatics methods to identify genes whose expression was differentially induced by sorafenib and regorafenib in HCC. We identified KIF14 as an oncogene involved in the acquired resistance to sorafenib in HCC and investigated its potential as a target for reversing this resistance. Sustained exposure of resistant HCC cells to sorafenib activated the AKT pathway, which in turn upregulated KIF14 expression by increasing expression of the transcription factor ETS1. Silencing KIF14 reversed the acquired resistance to sorafenib by inhibiting AKT activation and downregulating ETS1 expression by blocking the AKT-ETS1-KIF14 positive feedback loop. Moreover, injection of siKIF14 with sorafenib suppressed growth of sorafenib-resistant HCC tumors in mice. These results demonstrate that targeting KIF14 could be an effective means of reversing sorafenib failure or strengthening sorafenib's antitumor effects.Immune infiltration is associated with osteosarcoma metastasis. However, previous studies have not accounted for the functional diversity of the cells involved in the immune response. We conducted a comprehensive comparative analysis of the tumor-infiltrating immune cells in metastatic and non-metastatic osteosarcoma tissues based on a deconvolution algorithm (CIBERSORT). Twenty-two immune cell subsets were evaluated for their association with the presence or absence of metastasis in osteosarcoma patients. A lack of monocytes was associated with osteosarcoma metastasis; however, the levels of M1 macrophages, M2 macrophages and other immune cell subsets did not differ between the metastatic and non-metastatic groups. Additionally, a higher proportion of monocytes was associated with a better prognosis in osteosarcoma patients. Animal experiments demonstrated that the number of metastatic nodules was higher in mice lacking patrolling monocytes than in control mice. Our data indicated that the cellular composition of the immune infiltrate may subtly differ among osteosarcoma patients, and that patrolling monocytes inhibit osteosarcoma metastasis to the lungs of mice. Thus, the composition of the immune infiltrate and the level of patrolling monocytes may be important determinants of whether metastasis occurs in osteosarcoma patients.This study aimed to identify long non-coding RNAs (lncRNAs), microRNAs (miRNAs), and messenger RNAs (mRNAs) differentially expressed (DE) during keloid formation, predict DElncRNA-DEmiRNA-DEmRNA interactions, and construct a competing endogenous RNA (ceRNA) network through secondary data mining of keloid-related sequencing and microarray data in the open-source Gene Expression Omnibus (GEO) database. The GSE113621 dataset was downloaded from the GEO database, |log2FC|>1 and p 0.95 was selected as the index to predict the targeting relationships among lncRNAs, miRNAs, and mRNAs; and a network diagram was constructed using Cytoscape. The expression of 2356 lncRNAs was changed in the keloid-prone group-1306 were upregulated and 1050 were downregulated. Six lncRNAs, namely, 2 upregulated (DLEU2 and AP000317.2) and 4 downregulated (ADIRF-AS1, AC006333.2, AL137127.1 and LINC01725) lncRNAs, were expressed only in the keloid-prone group and were used to construct a ceRNA network. DLEU2 may regulate fibroblast proliferation, differentiation, and apoptosis through hsa-miR-30a-5p/hsa-miR-30b-5p. In-depth mining of GEO data indicated that lncRNAs and a ceRNA regulatory network participate in the wound healing process in keloid-prone individuals, possibly providing novel intervention targets and treatment options for keloid scars.Quality gaps exist in the hepatitis C virus (HCV) care process from diagnosis to cure. To better understand current gaps and to identify targets for quality improvement, we constructed an HCV care cascade in a patient-centered medical home (PCMH) with an emphasis on the specialty referral process. We performed a retrospective study of HCV-infected patients in a PCMH using electronic health record (EPIC) data. Patients with a first positive HCV RNA between 2012 and 2019 were included. With an adaptation to analyze linkage to specialty care, we created an HCV care cascade that included the following (1) a positive HCV RNA, (2) referral to a specialty provider, (3) a scheduled specialty appointment, (4) attendance at a specialty visit, (5) prescription for HCV therapy, and (6) evidence of sustained virological response (SVR). Patient and referring clinician characteristics were analyzed at each step of the care pathway, and the proportion of patients completing each step was calculated. Of the 256 HCV RNA-positive patients, 229 (89.5%) received a specialty referral; 215 (84.0%) had an appointment scheduled; 178 (69.5%) attended the specialty appointment; 116 (45.3%) were prescribed antiviral therapy; and 87 (34.1%) had documented SVR during the study period. Of the 178 patients attending a specialty visit, 62 (34.8%) did not receive a prescription, and the barrier most often noted was the desire for further workup (40.3%). Gaps occur at all stages of the HCV care continuum, with drop-offs in care occurring both before and after linkage to specialty care.Atrial fibrillation (AFIB) is the most common heart rhythm abnormality and is associated with significant morbidity and mortality. While the treatment of AFIB involves strategies of rate with or without rhythm control, it is also essential to strategize appropriate therapies to prevent thromboembolic complications arising from AFIB. Previously, anticoagulation was the main treatment option which exposed patients to higher than usual risk of bleeding. Guadecitabine However, with the advent of new technology, novel therapeutic options aimed at surgical or percutaneous exclusion or occlusion of the left atrial appendage in preventing thromboembolic complications from AFIB have evolved. This review evaluates recent advances and therapeutic options in treating AFIB with a special focus on both surgical and percutaneous interventions which can reduce and/or eliminate thromboembolic complications of AFIB.Germ cell tumours (GCT) are the most common testicular neoplasms, seen mainly in young adults. Rarely they can affect extragonadal tissues, either as primary tumours or as metastases, most commonly to retroperitoneal lymph nodes. A 'burned-out' testicular tumour is a metastatic GCT with a relatively occult primary testicular tumour, which has histologically spontaneously regressed. We report a case of a 26-year-old man who presented with an acute history of lower back pain and leg swelling. CT demonstrated a large retroperitoneal soft tissue mass causing right-sided hydronephrosis with inferior vena cava and iliofemoral vein thrombosis. Although clinical examination of the testis was normal, ultrasound imaging of the scrotum identified a burned-out testicular primary. Orchiectomy confirmed the diagnosis and the patient responded well to chemotherapy, with no viable residual tumour on follow-up imaging. However, despite nephrostomy insertion, a dimercaptosuccinic acid (DMSA) scan demonstrated loss of function of the right kidney after treatment.Fungal endocarditis, specifically from Candida species, is a rare but serious infection with a high mortality rate. Most cases occur in bioprosthetic or mechanical valves and are uncommon in native, structurally normal valves. When Candida endocarditis is detected and appropriate treatment is initiated earlier, there is an improvement in mortality. While the recommendation is usually to treat with a combination of surgery and antifungal medications, patient comorbidities may limit treatment options.We report the case of a 70-year-old Japanese man who was referred from a local urologist because of acute urinary retention (detrusor underactivity revealed by a urodynamics examination). A neurogenic urinary retention workup failed to reveal the aetiology, but a spinal tap incidentally showed occult meningeal reaction with positive oligoclonal band. The patient had no headache, nausea/vomiting or fever. Considering his clinical laboratory findings, his neural lesions seemed to involve the meninges and spinal cord, suggestive of 'form fruste' meningitis-retention syndrome. When clinicians encounter patients with urinary retention of undetermined aetiology, a spinal tap should be considered.Although more than 100 cases of genitourinary neurofibromas have been reported, only 16 cases of solitary neurofibroma arising in the penis have been reported in English literature. There can be diffuse or localised pelvic involvement in cases of neurofibromatosis and sometimes these masses can extend into and disfigure the external genitalia. We report an unusual case of plexiform neurofibroma arising from penis and review the literature on penile neurofibromas.Filtered back projection was used in computed tomography (CT) but produced low-dose CT images that were noisy and included artifacts. Iterative reconstruction was introduced, which reduced noise and demonstrated dose reduction; however, reconstruction times were lengthy and noise texture appeared unnatural. Now, artificial intelligence (AI), is being applied to CT image reconstruction. These algorithms are fast and produce images comparable to those produced by iterative reconstruction. This article outlines image reconstruction techniques, including a generalized framework for deep learning. Ethics of AI in radiology also is discussed.Fetal magnetic resonance (MR) imaging has evolved into a valuable complementary diagnostic tool when sonography findings are inconclusive. Technological advances in MR imaging pulse sequences have made it possible to obtain quality images from fetal imaging. The ability of MR imaging to create higher resolution images is useful in fetal neural imaging to characterize malformations, hemorrhages, and other pathologies. Although no evidence supports the concerns that MR imaging harms fetuses, caution should still be taken.Hydronephrosis, or dilation of the renal collecting system, can be diagnosed using various modalities, including sonography, radiography, magnetic resonance imaging, and nuclear medicine technology. This article explores the causes of hydronephrosis and its effects on the urinary system, presenting signs, symptoms, diagnostic techniques, and the role of various imaging specialists. In addition, the grading scale for hydronephrosis is presented and treatment options are explained.
To point out the need for standardized terminology for digital image analysis and to collect data by surveying radiologic technology professionals for a more comprehensive, national-breadth study.

A mixed-method pilot study was conducted, in which a survey was emailed to 4 Joint Review Committee on Education in Radiologic Technology-accredited radiography programs in July and August 2019. Eight educators and 28 radiologic technologists responded, and acceptance was evaluated on 3 of the proposed terms signal, signal value, and signal variance (later changed to signal differences). Quantitative data results were analyzed in Microsoft Forms and percentage of acceptance rates calculated. Respondents who did not accept the proposed terms were asked to provide reasoning in open-ended responses, which were analyzed using manual coding and categorization.

The term
