Abstract	Indirect carotid cavernous fistulas (ICCFs) are rare disease entities triggered by indirect low flow between the cavernous sinus and the meningeal branches of the internal or external carotid artery or from both. To evaluate clinical characteristics, angiography, and relationship to the result of endovascular treatment of indirect carotid cavernous fistulas. A prospective study of 32 patients diagnosed to identify ICCFs through digital subtraction angiography (DSA) and intravascular intervention. Results showed that indirect carotid cavernous fistulas were more common in females of advanced age (68.8%) and occurred spontaneously (87.5%); the most common symptoms included chemosis (93.75%), headache (87.5%), proptosis (53.1%), and tinnitus (37.5%) with type D being the most common (81.2%). Thirty out of thirty-two patients with intervention had complete flow block (83.3%), near complete (13.3%), and failure in one case. Incomplete occlusion interventions and failures were of the type D complication. The complication and number of drainage veins are related (p<0.05). ICCFs have diverse symptoms that depend on the drainage veins but most commonly were red eyes, headache, and protruding eyes. The ICCFs were mostly D-type formation and endovascular treatments were safe and effective. Common complications occurred in the case of many veins draining.

Abstract	The construction industry is one of the key industries with high potential for the circular economy; the promotion of reuse and recycling of construction and demolition waste (CDW) is essential for sustainable urban development. In this study, a series of compaction, California bearing ratio, saturated hydraulic conductivity, and particle breakage tests of well– and poor–graded mixtures of recycled clay brick aggregates (RCBs) and recycled concrete aggregates (RCAs) with maximum aggregate diameters of 19, 25, and 37.5 mm were carried out to examine the practical application of those mixtures to unbound roadbed materials in Vietnam. The experimental results suggest that the maximum amount of RCBs added to RCAs should be less than 30% when applied to unbound roadbed materials. In addition, it was found that the mixing proportions of RCBs and RCAs and the maximum aggregate diameter, gradation of aggregates, and initial moisture condition control the saturated hydraulic conductivity. Further, the particle breakage characteristics under compaction were carefully examined, and it was found that the percentage increment/decrement, as well as a newly introduced method of estimating the mixing proportions of RCAs and RCBs in the fine fraction (<2.36 mm), is effective in understanding the mechanism of particle breakage of RCA and RCB mixtures.

Abstract	Direct anterior cerebral artery-cavernous sinus fistula is an extremely rare complication of head trauma. We describe a male patient (age 49 years) with a history of head trauma 15 years ago who was hospitalised for a bulging red eye and tinnitus. Digital subtraction angiography showed a direct anterior cerebral artery (fork junction A1 - prior passage)-cavernous sinus fistula. The patient was treated with arterial endovascular intervention, complete sealing of the fistula orifice using coils. He was discharged 5 days later with no symptoms of a bulging red eye, ringing in the ears, or nerve paralysis. Re-examination after 3 months of stable clinical features did not show recurrent fistula. In conclusion, anterior cerebral artery-cavernous sinus fistula is an extremely rare lesion, and arterial endovascular intervention using coils is a safe and effective method for treatment of such lesion.

Abstract	Introduction: Deconstructive versus reconstructive technique remains controversial on the management of acute basilar tip artery dissection. Aim: We introduced a case report of massive dissecting aneurysm in the basilar tip artery treated with intra-aneurysm and basilar artery coiling. Results: A 30-year-old male presented with sudden headache and severe vomiting. Radiographic study showed a large unruptured dissecting aneurysm in the basilar tip artery involving bilateral P1 segment. This aneurysm was treated with intra-aneurysm and basilar artery coiling. Patient was discharge after 7 days without any neurological deficits. Post-operatively, the patient received 75 mg aspirin and 75 mg clopidogrel PO per day for 3 months - then 75 mg aspirin per day for up to 1 year. Angiographic follow-up at 3 months showed a complete occlusion of aneurysmal sac and basilar tip artery without any deficits (mRS 0). Cerebral arteriography at 6 months follow-up confirmed a stable occlusion of aneurysmal sac with a minor recurrence of aneurysm in left P1 segment. Conclusion: Intra-aneurysm and basilar artery coiling is valuable alternative technique to treat complex basilar tip dissecting aneurysm in case of infeasible reconstructive technique. Clinical presentation, aneurysm characteristics and collateral circulation have to be investigated on each case to adopt this technique.

Abstract	Background: Plasmodium falciparum has acquired resistance to artemisinin in Southeast Asia, with mutations in the P. falciparum Kelch-13 (Pfk13) gene associated with the resistance phenotype. The widespread use of Artemisinin-based combination therapy (ACT)s in Southeast Asia has led to the selection and spread of parasites carrying mutations in Pfk13. We characterised the allele diversity of Pfk13 and pfg377, an artemisinin-resistance neutral polymorphic gene, in parasite DNA extracted human blood from in southern Vietnam in 2003, 2012, 2015 and 2018. Method: This study was conducted in Bu Gia Map commune, Binh Phuoc province, Vietnam, from May 2018 to January 2019. Twenty-four samples from 2018 to 2019, 30 from 2003, 24 from 2012 and 32 from 2015 were analysed. Malaria-infected human blood was collected by finger-prick and used for molecular analysis. A nested-PCR targeting the small subunit ribosomal RNA gene was used for Plasmodium species identification, followed by amplification and nucleotide sequencing of Pfk13 and region 3 of pfg377. Archived blood samples collected in the same region in 2012 and 2015 were also analysed as above for comparison. Results: The genetic diversity of Pfk13 and pfg377 was lower in 2018-2019 compared to 2012 and 2015. The number of distinct Pfk13 mutants decreased from three in 2012 and 2015, P553L, V568G and C580Y, to one, C580Y in 2018-2019. In 2018-2019, the frequency of C580Y mutant strains was 71% (17/24 isolates). All samples were wild type in 2003. In 2012 and 2015, there were single-strain infections as well as co-infections with two mutant strains or with mutant and wild strains, whereas there were no co-infections in 2018. pfg377 allele diversity decreased from five alleles in 2012 to two alleles in 2018-2019. Conclusion: The genetic diversity of P. falciparum was reduced at the two genetic loci surveyed in this study, Pfk13 and pfg377. In the case of the former gene, we observed an increase in the prevalence of parasites carrying the C580Y gene, known to confer reduced susceptibility to ACTs. The reduction in the diversity of pfg377 may be linked to the clonal expansion of parasite strains carrying the C580Y mutation, leading to an overall reduction in parasite genetic diversity across the population.

Abstract	Background: Programmed cell death-1 (PD-1) variants and circulating level of soluble PD-1 are associated with susceptibility to malignant and infectious disease. This study aimed to examine the association of PD-1.5 and PD-1.9 variants, and plasma sPD-1 level with hepatitis B virus (HBV) infection and disease progression. Methods: The study cohort consisted of adults infected with HBV (n=513) - stratified by clinical course, including chronic hepatitis B (CHB, n=173), liver cirrhosis (LC, n=134) and hepatocellular carcinoma (HCC, n=206) - and matched healthy controls (HC, n=196). The PD-1.5 (rs2227981 C/T) and PD-1.9 (rs2227982 C/T) genetic variants were genotyped by Sanger sequencing, and plasma sPD-1 levels were quantified by enzyme immunoassay. Results: Plasma sPD-1 levels were significantly higher among patients infected with HBV. The highest plasma sPD-1 levels were observed in patients with CHB, followed by patients with LC and HCC. In addition, the plasma sPD-1 levels correlated positively with liver inflammation [aspartate transaminase (AST): rho=0.57, P<0.0001; alanine aminotransferase: rho=0.57, P<0.0001], and were positively correlated with liver fibrosis [AST to platelet ratio index score: rho=0.53, P<0.0001). The PD-1.9 TT genotype was less common in patients with CHB compared with patients with LC, HCC, and HCC+LC in both codominant and recessive models (P<0.01), and was found to be a risk factor for HCC predisposition {HCC vs non-HCC: odds ratio (OR) 2.0 [95% confidence interval (CI) 1.13-3.7], P Conclusion: sPD-1 level was associated with liver inflammation and progression of liver fibrosis, and the PD-1.5 and PD-1.9 variants were associated with HBV infection and progression of liver disease.

Abstract	Abstract Background Postherpetic neuralgia (PHN) is the most common and bearable complication of herpes zoster (HZ). This pain may have negative impact on the patient's all aspects of daily life and health‐related quality of life (HRQOL). Despite numerous advances in treatment, many patients remain resistant to the current therapy options. It is the first time subcutaneous injection of methylprednisolone acetate and lidocaine has been used to treat refractory PHN. We report the results of this treatment evaluating pain relief and HRQOL improvement in this disorder. Methods A total of 43 patients with refractory PHN was enrolled in the observational study. All patients received daily subcutaneous injection of methylprednisolone acetate and lidocaine for 10 consecutive days. The severity of pain was assessed by using Visual Analog Scale (VAS), and 36‐Item Short Form Survey (SF‐36) was applied to evaluate HRQOL. Assessment of the pain and HRQOL was carried out at baseline and posttreatment at 4 weeks as well as 6 and 12 months. Results At baseline, all patients experienced severe PHN with average VAS scores of 8.44 ± 0.85 (minimum 7; maximum 10). At 4 weeks, 6 months, and 12 months after treatment, the pain had significantly decreased (P < .001), and all subjects showed significant improvement in all eight domains of HRQOL. No major adverse events associated with the subcutaneous injection were observed. Conclusions Our results indicate that subcutaneous injection of methylprednisolone acetate and lidocaine can be an effective and safe treatment for PHN.
