RESUMO

BACKGROUND AND AIMS: To measure the impact of socio-economic environment on the incidence of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). METHOD: The study used data from the French Network of Cancer Registries (FRANCIM) between 2006 and 2016. Classification of patients into HCC and iCCA was performed according to the topographical and morphological codes of the 3rd edition of the International Classification of Diseases for Oncology. Patient addresses were geolocalized and assigned to an IRIS, the smallest French geographic unit. Socio-economic environment was assessed by the European Deprivation Index (EDI). Sex- and age-standardized incidence rates with 95% confidence intervals (CI) were estimated per 100 000 inhabitants, by national quintiles, for each IRIS, sex and age group. Quintile 1 (Q1) characterized the most affluent areas. A Poisson regression was performed to model the impact of deprivation. RESULTS: We included 22 249 cases (79.64% HCC, 16.97% iCCA). Incidence rates were 11.46 and 2.39 per 100 000 person-years for HCC and iCCA, respectively. There was an over-incidence of HCC in quintiles 2, 3, 4 and 5 compared to quintile 1: Q1 10.28 [9.9-10.66] per 100 000 person-years, Q2 11.43 [10.48-12.47] (p < .0001), Q3 11.81 [10.82-12.89] (p < .0001), Q4 12.26 [11.25-13.37] (p < .001) and Q5 11.53 [10.57-12.57] (p < .0001). By contrast, there was no difference for iCCa. Deprivation was significantly associated with HCC in men (p = .0018) and women (p = .0009), but not with iCCA (p = .7407). CONCLUSION: The incidence of HCC is related to socio-economic environment, unlike iCCA. HCC and iCCA should be studied separately in epidemiological studies.

RESUMO

BACKGROUND AND AIMS: Non-O blood group promotes deep vein thrombosis and liver fibrosis in both general population and hepatitis C. We aimed to evaluate the influence of Non-O group on the outcome of Child-Pugh A cirrhotic patients. METHODS: We used two prospective cohorts of Child-Pugh A cirrhosis due to either alcohol or viral hepatitis. Primary end point was the cumulated incidence of 'Decompensation' at 3 years, defined as the occurrence of ascites , hydrothorax, encephalopathy, gastrointestinal bleeding related to portal hypertension, or bilirubin >45 µmol/L. Secondary end points were the cumulated incidences of (1) 'Disease Progression' including a « decompensation¼ or « the occurrence of one or more parameters ¼ among: prothrombin time (PT) <45%, albumin <28 g/L, Child-Pugh worsening (B or C vs A or B, C vs B), hepatorenal syndrome, and hepato-pulmonary syndrome, (2) other events such as non-malignant portal vein thrombosis (nmPVT), and (3) overall survival. RESULTS: Patients (n = 1789; 59.9% Non-O group; 40.1% group O) were followed during a median of 65.4 months. At 3 years cumulated incidence of Decompensation was 8.3% in Non-O group and 7.2% in group O (P = .27). Cumulated incidence of Disease Progression was 20.7% in Non-O group and 18.9% in group O (P = .26). Cumulated incidence of nmPVT was 2.7% in Non-O group and 2.8% in group O (P = .05). At 3 years overall survival was 92.4% in Non-O group and 93.4% in group O (P = 1). CONCLUSION: Non-O group does not influence disease outcome in Child-Pugh A cirrhotic patients. Clinicals trial number NCT03342170.

RESUMO

OBJECTIVES: HIV resistance to the integrase inhibitor raltegravir in treated patients is characterized by distinct resistance pathways. We hypothesize that differences in the in vivo dynamics of HIV resistance to raltegravir are due to the genetic context of the integrase present at baseline. PATIENTS AND METHODS: We studied four patients whose viruses evolved towards different resistance pathways. The integrase baseline sequences were inserted into a reference clone. Primary resistance mutations were then introduced and their impact on viral replication capacity (RC) and resistance was measured. RESULTS: Patients A and B experienced emergence and persistence of mutation N155H under raltegravir therapy. In the integrase sequence from Patient A, N155H conferred potent resistance coupled with a lower impact on RC than Q148H. In Patient B, instead, selection of N155H could be explained by the dramatic loss of RC induced by the alternative Q148H mutation. In Patient C, N155H initially emerged and was later replaced by Q148H. In this integrase context, N155H resulted in higher RC but lower resistance than Q148H. In Patient D, Q148H rapidly emerged without appearance of N155H. This was the only patient for whom Q148H conferred higher RC and resistance than N155H. CONCLUSIONS: The emergence of different resistance mutations in patients was in full agreement with the impact of mutations in different baseline integrase contexts. Evolution towards different resistance genotypes is thus largely determined by the capacity of different integrase sequences present at baseline to minimize the effect of mutations on virus RC while allowing expression of resistance.

RESUMO

Adrinandra megaphylla Hu is a medicinal plant belonging to the Adrinandra genus, which is well-known for its potential health benefits due to its bioactive compounds. This study aimed to assemble and annotate the chloroplast genome of A. megaphylla as well as compare it with previously published cp genomes within the Adrinandra genus. The chloroplast genome was reconstructed using de novo and reference-based assembly of paired-end reads generated by long-read sequencing of total genomic DNA. The size of the chloroplast genome was 156,298 bp, comprised a large single-copy (LSC) region of 85,688 bp, a small single-copy (SSC) region of 18,424 bp, and a pair of inverted repeats (IRa and IRb) of 26,093 bp each; and a total of 51 SSRs and 48 repeat structures were detected. The chloroplast genome includes a total of 131 functional genes, containing 86 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. The A. megaphylla chloroplast genome indicated that gene content and structure are highly conserved. The phylogenetic reconstruction using complete cp sequences, matK and trnL genes from Pentaphylacaceae species exhibited a genetic relationship. Among them, matK sequence is a better candidate for phylogenetic resolution. This study is the first report for the chloroplast genome of the A. megaphylla.

RESUMO

Patients with cirrhosis are prone to develop bacterial infections, which consist in one of the major precursors of Acute-on-Chronic Liver Failure (ACLF) and are responsible for a high mortality rate. In recent years, the management of bacterial infections in patients with cirrhosis has become increasingly complicated due to a change in bacterial ecology associated with a higher rate of cocci gram positive bacteria in Europe and America along with the emergence of a multidrug-resistant (MDR) and extensively drug-resistant (XDR) bacteria leading to a decrease in the efficacy of empirical strategies based on the administration of third-generation cephalosporins. MDR and XDR now account for about 40% of the infections worldwide, and up to 70% in India. Among them, the most common ones are extended-spectrum beta-lactamase producing (ESBL-P) bacteria, carbapenem-resistant enterobacteriaceae (CRE), Methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). An early diagnosis associated to an empirical antibiotic adapted to the site of infection and potential bacterial resistance is now crucial in order to improve the chances of survival and contain the resistance phenomenon. Moreover, a fungal infection must always be discussed in these high-risks patients, especially in the absence of clinical improvement under appropriate antibiotic treatment. In this review, we will focus on the emerging threat of MDR and XDR organisms, as well as fungal infections, in order to better adapt the therapeutic management of cirrhotic patients with infections.

RESUMO

BACKGROUND: Despite the availability of antitoxin and antibiotics, the mortality rate for diphtheria remains high, mostly because of cardiac complications. METHODS: During 1 year, 154 Vietnamese children with diphtheria admitted to a referral hospital were studied prospectively with clinical examination, including a simple pseudomembrane score, 12-lead and 24-hour electrocardiography, measurement of serum cardiac enzyme levels, and estimation of troponin T levels. RESULTS: Thirteen children had diphtheritic cardiomyopathy on admission, and 19 developed it subsequently. Twelve children (8%) died. The combination of pseudomembrane score of >2 and bull neck predicted the development of diphtheritic cardiomyopathy, with a positive predictive value of 83% and a negative predictive value of 93%. Administration of 24-hour electrocardiography on admission improved the ability to predict diphtheritic cardiomyopathy by 57%. Fatal outcome was best predicted by the combination of myocarditis on admission and a pseudomembrane score of >2. Of the cardiac enzyme levels measured, an elevated aspartate aminotransferase level was the best predictor. The presence of troponin T identified additional children with subclinical cardiac damage. CONCLUSIONS: The development of diphtheritic cardiomyopathy can be predicted by means of simple measures.
