Introduction:The advancement of gender equality within radiology, a predominantly male profession, has currently been a significant concern. Aim: Therefore, in this original study, we aimed to investigate the gender disparity in Vietnamese radiological societies. Methods: No ethical committee or institutional review board approval was needed since the data were publicly available. In this retrospective study, we evaluated the faculties of four main radiological societies in Vietnam: Vietnamese society of radiology and nuclear medicine (VSRNM, n = 67); Radiological society of Ho Chi Minh City (RSHCM, n = 25); Vietnamese society of ultrasound in medicine (VSUM, n = 29); and Vietnamese society of interventional radiology (VSIR, n = 18). Results: There are significantly fewer women than men in faculties of four main radiological societies (15.1% vs. 84.9%). None of the women served as a professor and leader of any radiological societies. The women with a doctor of philosophy level are relatively low among the four main radiological societies. Also, female interventional and pediatric radiologists are seriously low among four main radiological societies. Conclusions: In Vietnamese radiological societies, gender disparities exist, especially about educational degrees and professorship positions. Future studies are essential to address the underlying roots of the gender gap and aid in the implementation of gender diversity programs and policies.

Introduction: Pseudo journals, hijacked journals, fraudulent journals, fake journals, and predatory journals waste valuable research when authors publish their studies in them. Aim: This article described novel suggested features for the identification of fraudulent journals and aimed to explain this issue to help inexperienced scientists avoid publishing in predatory journals. Methods: The articles related to this topic in were retrieved from PubMed and trustable Internet sources. Results: Unfortunately, some fake journals have made their way into reputable databases, such as PubMed, PubMed Central, MEDLINE, SCOPUS, and Web of Science; thus, the serious question has been raised regarding how we should address this problematic phenomenon. We recommended 28 suggested characteristics of predatory journals for readers to take into consideration. Conclusion: Unaware of the detrimental effects associated with publishing in disreputable journals, inexperienced researchers can fall victim to them. Together, as both readers and writers, we should completely boycott predatory journals.

Purpose: The purpose of this study was to evaluate the safety and efficacy of mechanical thrombectomy with a direct aspiration first-pass technique (ADAPT) using large-bore catheters in patients with acute ischemic stroke due to large vessel occlusion (LVO) in a hospital in Vietnam. Methods: This was a retrospective review of patients with acute ischemic stroke due to LVO who were diagnosed and underwent mechanical thrombectomy using ADAPT with large-bore catheters at Bach Mai Hospital from January 2017 to June 2018. Results: Seventy-three patients (47.9% female; age: 61.29 ± 14.49 years) met study criteria. The average procedure duration was 45.09 ± 38.26 min. Successful recanalization post-ADAPT (thrombolysis in cerebral infarction 2b-3) was achieved in 72.6% (53/73) of patients. Good functional outcome (Modified Rankin Scale 0–2) at 3 months was achieved in 50.7% (37/73), with poor functional outcome in 24.7% (18/73). The 90-day mortality rate was 24.7% (18/73). The hemorrhagic transformation rate was 31.6%, in which 19.2% were symptomatic. Vessel perforation occurred in 5.5% (4/73) of patients but in all cases was associated with the guidewire and not the reperfusion catheter. Vessel dissection occurred in 1.4% (1/73) and vasospasm in 5.5% (4/73) of patients. Conclusion: Mechanical thrombectomy using ADAPT with large-bore catheters for acute ischemic stroke due to LVO is a method that yielded good results in recanalization and clinical recovery in a Vietnamese patient population.

For certain clinical circumstances, the differentiation between cerebellar medulloblastoma and brainstem glioma is essential. We aimed to evaluate the role played by the apparent diffusion coefficient (ADC) values in the differentiation between cerebellar medulloblastomas and brainstem gliomas in children. The institutional review board approved this prospective study. Brain magnetic resonance imaging (MRI), including diffusion-weighted imaging (DWI) and ADC, was assessed in 32 patients (median age: 7.0 years), divided into two groups, a medulloblastoma group (group 1, n = 22) and a brainstem glioma group (group 2, n = 10). The Mann–Whitney U test was utilized to compare tumor ADCmax, ADCmin, ADCmean, and ADCsd values, and their ratios with the parenchyma values between the two groups. Receiver operating characteristic (ROC) curve analysis and the Youden index were used to calculate the cut-off value, along with the area under the curve (AUC), sensitivity, and specificity. The median ADCmax, ADCmin, and ADCmean values were significantly higher in group 2 than in group 1 (p < 0.05). The median ratios of ADCmin and ADCmean to the parenchyma were significantly higher in group 2 than in group 1 (p < 0.05). The ROC analysis showed that the AUC for the ADCmean ratio was the highest among these parameters, at 98.2%. The ADCmean tumor to parenchyma ratio was a significant and effective parameter for the differentiation between pediatric medulloblastomas and brainstem gliomas.
