A xenograft model was used to evaluate the role of circSEC24A in vivo. circSEC24A expression was significantly upregulated in HCCLM3 and Hep3B cells. Silencing circSEC24A mitigated the proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of HCC cells, which was abrogated by downregulation of miR-421. Meanwhile, MMP3 could bind to miR-421 to decrease the functional effects of miR-421 and induce tumor metastasis. Knockdown of cicSEC24A suppressed tumor growth in vivo. circSEC24A interference suppressed HCC cell EMT by sponging miR-421, further regulating MMP3, and inhibiting tumor growth in vivo. Therefore, circSEC24A could represent a potential target for HCC patient treatment.Trigger finger is a common hand disorder; however, its pathogenesis remains unknown. In this study, we aimed to investigate mast cells, fibroblast activators that synthesize collagen, in the tendon sheaths of trigger fingers. We investigated the presence of mast cells and their association with changes in the collagen content of the tendon sheath and clinical data. We performed a multicenter prospective study of 77 adult patients with trigger finger who had undergone resection of the first annular pulley between August 2012 and January 2020. The tendon sheath was immunostained with an anti-tryptase antibody to confirm mast cell presence. The percentage of collagen in the tendon sheath was determined by picrosirius red staining observed through a polarization microscope. The clinical data, including the duration from symptom onset to surgery, severity, pain numerical rating scale, and Hand20 scores, were evaluated. Tryptase-positive mast cells were recognized in 83.5% of all specimens. The mast cell presence group (Group P) had a significantly higher percentage of type-3 collagen in the tendon sheath than the non-mast cell presence group (Group N) (Group P, 15.6%; Group N, 12.7%; p = 0.03). Moreover, Group P had significantly higher pain numerical rating scale (Group P; 5, Group N; 3, p = 0.04) and Hand20 (Group P; 35.5, Group N; 13.0, p = 0.01) scores than Group N. These findings suggest that mast cell presence in the tendon sheath of the trigger finger is related to the pathology and clinical symptoms of trigger finger.
With the availability of multiple treatment options for metastatic castration-resistant prostate cancer (mCRPC), new real-world data on disease management and drugs' performance are needed.

We described characteristics, management and clinical outcomes of patients receiving first-line mCRPC treatment within the Italian cohort of the real-world, prospective, international Prostate Cancer Registry. Almonertinib Patients were enrolled consecutively (2013-2016) in 32 Italian sites and followed for 3 years.

238 patients were included 157 received first-line abiraterone acetate plus prednisone ("abiraterone" thereafter) and 70 first-line docetaxel; 11 patients receiving other treatments were not considered. Compared with docetaxel-treated patients, those receiving abiraterone were significantly older (age ⩾75 63.7% vs 38.6%), less frequently had a Gleason score >8 (48.2% vs 67.6%, p<0.005) at initial diagnosis, and more frequently an ECOG score ⩾1 (52.7% vs 36.2%, p<0.05) and comorbidities (76.4% vs 57.1%, p<0.05) at baseline; they reported a lower analgesic use (15.3% vs 30%, p<0.005). In the abiraterone group (median follow-up 22.1 months), median time to progression (TTP) and progression-free survival (PFS) were, respectively, 14.4 months (95% confidence interval, CI, 10.6-18.0) and 13.0 months (95% CI, 9.1-16.8); median overall survival (OS) was not reached, and 3-year OS was 59.1%. In the docetaxel treatment group (median follow-up 25.3 months), median TTP, PFS and OS were, respectively, 8.2 months (95% CI, 6.1-10.3), 8.2 months (95% CI, 5.8-10.3) and 33.2 months (95% CI, 19.2-not estimable).

This investigation provided valuable information on the overall mCRPC treatment pattern and the effectiveness of first-line abiraterone and docetaxel in a population representative of everyday practice.

Synchronous aortic dissection (AD) with involvement of pre-existing infrarenal abdominal aortic aneurysms (AAAs) are fortunately rare. Extension of the dissection flap to involve the aneurysm is particularly dangerous with pressurization of the false lumen within a diseased aortic wall. The aim of this article is to present a unique case of an acute AD with extension to involve a large AAA in a patient with an underlying connective tissue disorder.

A 24-year-old male Marfan syndrome patient with prior type A dissection repair presented with a descending thoracic AD and a separate 7.0-cm infrarenal AAA. He was initially medically managed but developed acute extension of the dissection flap to involve the large aneurysm.

The patient was initially treated with open infrarenal aortic replacement under left atrialfemoral artery bypass. Three years later, he developed degeneration of the residual aorta and underwent a two-stage hybrid repair. He underwent an additional stent graft for a distal anastomotic leak. At 5years of follow-up, there was positive aneurysm remodeling and sac regression.

This case illustrates the challenges in treating a patient with synchronous aortic processes. False lumen pressurization of a large aneurysm wall is fortunately rare but can be lethal. Prompt intervention is required but the presence of an underlying connective tissue disorder may limit endovascular treatment options. Careful case planning is mandatory and multiple interventions should be anticipated.

Several studies have reported favorable outcomes of nonspecific interstitial pneumonia (NSIP); however, its prognosis and prognostic factors remain unclear. This study aimed to determine the outcomes of fibrotic NSIP and the prognostic factors for progression, relapse, and survival.

In this retrospective study, we reviewed the clinical data of 204 patients diagnosed with fibrotic NSIP by surgical lung biopsy at Samsung Medical Center. The factors associated with survival and disease progression or relapse were determined using Cox proportional hazard analysis.

The median age of patients was 54 years and 67 (33%) patients were male. Also, 47 patients (23%) were current or ex-smokers. In all, 141 (69%) patients were diagnosed with idiopathic NSIP, while 63 (31%) patients were associated with connective tissue diseases. Progression or relapse was observed in 100 (49%) patients. The 5-year and 10-year survival rates were 94.6% and 90.4%, respectively. The factors associated with disease progression and relapse were diffusing capacity for carbon monoxide (DLco) <60% [adjusted hazard ratio (HR), 1.739; 95% confidence interval (CI), 1.036-2.921;
 = 0.036], bronchoalveolar lavage (BAL) lymphocyte >15% (adjusted HR, 0.592; 95% CI, 0.352-0.994;
 = 0.047), and treatment with corticosteroid and azathioprine (adjusted HR, 0.556; 95% CI, 0.311-0.955;
 = 0.048). Disease progression or relapse was associated with mortality (adjusted HR, 7.135; 95% CI, 1.499-33.971;
 = 0.014).

Preserved lung function, BAL lymphocytosis, and treatment with corticosteroids and azathioprine were associated with lower risks of disease progression and relapse, which were risk factors for mortality.

Pediatric-onset (PO) multiple sclerosis (MS) accounts for about 2-10% of the total MS cases. Recently, a greater attention has been given to POMS, with substantial improvements in the understanding of its pathophysiology, in the diagnostic work-up and in the identification of reliable prognosticators associated with long-term disability in these patients.

This review summarizes the most recent updates regarding the pathophysiology of POMS, the current diagnostic criteria and the clinical, neuroradiological and laboratoristic markers that have been associated with disease progression (i.e. occurrence of a second clinical attack at disease onset and accumulation of disability in definite MS).

The study of POMS, where the clinical onset is closer to the biological onset of MS, may contribute to better understand how the different pathological processes impact brain maturation and contribute to disease progression, but also how brain plasticity may counterbalance structural damage accumulation. Although rarghly warranted.The COVID-19 pandemic has highlighted the critical role that animal models play in elucidating the pathogenesis of emerging diseases and rapidly analyzing potential medical countermeasures. Relevant pathologic outcomes are paramount in evaluating preclinical models and therapeutic outcomes and require careful advance planning. While there are numerous guidelines for attaining high-quality pathology specimens in routine animal studies, preclinical studies using coronaviruses are often conducted under biosafety level-3 (BSL3) conditions, which pose unique challenges and technical limitations. In such settings, rather than foregoing pathologic outcomes because of the inherent constraints of high-containment laboratory protocols, modifications can be made to conventional best practices of specimen collection. Particularly for those unfamiliar with working in a high-containment laboratory, the authors describe the logistics of conducting such work, focusing on animal experiments in BSL3 conditions. To promote scientific rigor and reproducibility and maximize the value of animal use, the authors provide specific points to be considered before, during, and following a high-containment animal study. The authors provide procedural modifications for attaining good quality pathologic assessment of the mouse lung, central nervous system, and blood specimens under high-containment conditions while being conscientious to maximize animal use for other concurrent assays.
Sickle cell disease (SCD) is the most common hemoglobinopathy in the world. Over 90% of those born with SCD live in low- and middle-income countries (LMICs), yet individuals in these settings have much poorer outcomes compared to those in high-income countries.

This manuscript provides an in-depth review of the cornerstones of basic SCD care, the barriers to implementing these in LMICs, and strategies to increase access in these regions. Publications in English language, peer-reviewed, and edited from 2000 to 2021 were identified on PubMed. Google search was used for gray literature.

Outcomes for patients with SCD in high-income countries have improved over the last few decades due to the implementation of universal newborn screening programs and use of routine antimicrobial prophylaxis, increase in therapeutic and curative options, and the adoption of specific measures to decrease risk of stroke. This success has not translated to LMICs due to several reasons including resource constraints. A combination of several strategies is needed to increase access to basic SCD care for patients in these settings.
