| 1 | Psychotropic drugs and liver disease:A critical review of pharmacokinetics and liver toxicity显示文摘The liver is the organ by which the majority of sub-stances are metabolized, including psychotropic drugs. There are several pharmacokinetic changes in end-stage liver disease that can interfere with the metabolization of psychotropic drugs. This fact is particularly true in drugs with extensive first--pass metabolism, highly protein bound drugs and drugs depending on phase I hepatic metabolic reactions. Psychopharmacological agents are also associated with a risk of hepatotoxicity. The evidence is insufficient for definite conclusions regarding the prevalence and severity of psychiatric drug-induced liver injury. High-risk psychotropics are not advised when there is pre-existing liver disease, and after starting a psychotropic agent in a patient with hepatic impairment, frequent liver function/lesion monitoring is advised. The authors carefully review the pharmacokinetic disturbances induced by end-stage liver disease and the potential of psychopharmacological agents for liver toxicity. | Diogo Telles-Correia António Barbosa Helena Cortez-Pinto Carlos Campos Nuno B F Rocha Sérgio Machado | 2017 | World Journal of Gastrointestinal Pharmacology and Therapeutics2017，8，1： | 3 |
| 2 | Genetic ancestry analysis in non-alcoholic fatty liver disease patients from Brazil and Portugal显示文摘AIM:To study the association between genetic ancestry,non-alcoholic fatty liver disease(NAFLD) metabolic characteristics in two cohorts of patients,from Brazil and Portugal. METHODS:We included 131 subjects from Brazil [(n = 45 with simple steatosis(S. Steatosis) and n = 86 with nonalcoholic steatohepatitis(NASH)] and 90 patients from Portugal(n = 66,S. Steatosis; n = 24,NASH). All patients had biopsy-proven NAFLD. In histologic evaluation NAFLD activity score was used to assess histology and more than 5 points defined NASH in this study. Patients were divided into two groups according to histology diagnosis:simple steatosis or non-alcoholic statohepatitis. Genetic ancestry was assessed using real-time polymerase chain reaction. Seven ancestry informative markers(AT3-I/D,LPL,Sb19.3,APO,FYNull,PV92,and CKMM) with the greatest ethnicgeographical differential frequencies(≥ 48%) were used to define genetic ancestry. Data were analyzed using R PROJECTS software. Ancestry allele frequencies between groups were analyzed by GENEPOP onlineand the estimation of genetic ancestry contribution was evaluated by ADMIX-95 software. The 5% alpha-error was considered as significant(P < 0.05). RESULTS:In the Brazilian sample,NASH was significantly more frequent among the elderly patients with diabetes(NASH 56 ± 1.1 years old vs S. Steatosis 51 ± 1.5 years old,P = 3.7 x 10-9),dyslipidemia(NASH 63% vs S. Steatosis 37%,P = 0.009),higher fasting glucose levels(NASH 124 ± 5.2 vs S. Steatosis 106 ± 5.3,P = 0.001) and Homeostatic Model of Assessment index > 2.5 [NASH 5.3(70.8%) vs S. Steatosis 4.6(29.2%) P = 0.04]. In the Portuguese study population,dyslipidemia was present in all patients with NASH(P = 0.03) and hypertension was present in a larger percentage of subjects in the S. Steatosis group(P = 0.003,respectively). The genetic ancestry contribution among Brazilian and Portuguese individuals with NASH was similar to those with S. Steatosis from each cohort(Brazilian cohort:P = 0.75; Portuguese cohort:P = 0.97). Nonetheless,the genetic ancestry contribution of the Brazilian and Portuguese population were different,and a greater European and Amerindian ancestry contribution was detected in the Portuguese population while a higher African genetic ancestry contribution was observed in Brazilian population of both NASH and S. Steatosis groups.CONCLUSION:There was no difference between the genetic ancestry contribution among Brazilian and Portuguese individuals with NASH and S. Steatosis from each cohort. | Lourianne Nascimento Cavalcante Jose Tadeu Stefano Mariana V Machado Daniel F Mazo Fabiola Rabelo Kiyoko Abe Sandes Flair Jose Carrilho Helena Cortez-Pinto Andre Castro Lyra Claudia P de Oliveira | 2015 | World Journal of Hepatology2015，7，10： | 2 |
| 3 | From regenerative strategies to pharmacological approaches:can we fine-tune treatment for Parkinson's disease?显示文摘Parkinson's disease is the second most prevalent neurodegenerative disorder worldwide.Clinically,it is characterized by severe motor complications caused by progressive degeneration of dopaminergic neurons.Current treatment is focused on mitigating the symptoms through the administration of levodopa,rather than on preventing dopaminergic neuronal damage.Therefore,the use and development of neuroprotective/disease-modifying strategies is an absolute need that can lead to promising gains on translational research of Parkinson's disease.For instance,N-acetylcysteine,a natural compound with strong antioxidant effects,has been shown to modulate oxidative stress,preventing dopamine-induced cell death.Despite the evidence of neuroprotective and modulatory effects of this drug,as far as we know,it does not induce per se any regenerative process.Therefore,it would be of interest to combine the latter with innovative therapies that induce dopaminergic neurons repair or even differentiation,as stem cell-based strategies.Stem cells secretome has been proposed as a promising therapeutic approach for Parkinson's disease,given its ability to modulate cell viability/preservation of dopaminergic neurons.Such approach represents a shift in the paradigm,showing that cell-transplantation free therapies based on the use of stem cells secretome may represent a potential alternative for regenerative medicine of Parkinson's disease.Thus,in this review,we address the current understanding of the potential combination of stem cell free-based strategies and neuroprotective/disease-modifying strategies as a new paradigm for the treatment of central nervous system neurodegenerative diseases,like Parkinson's disease. | Rita Caridade Silva Helena Sofia Domingues António J.Salgado Fábio G.Teixeira | 2022 | Neural Regeneration Research2022，17，5： | 2 |

| 14 | Cross-sectional study to determine viral hepatitis knowledge in different urban populations in Brazil显示文摘AIM To evaluate viral hepatitis knowledge among individuals from different resource areas and health conditions to identify possible gaps.METHODS A cross-sectional, descriptive study was carried out among 447 individuals from five distinct populations in Brazil: Southeast Viral Hepatitis Ambulatory(n = 100), South(n = 89) and Northeast(n = 114) Health Center, Southeast(n = 77) and Northeast(n = 67) low resource areas. All individuals answered a questionnaire assessing sociodemographic characteristics and viral hepatitis awareness. The perception was scored based on the average number of correct answers of all participants and categorized as 'low'(0-28 correct answers) or 'desirable'(29-46 correct answers). Associations between sociodemographic characteristics and perception were also evaluated.RESULTS A low level of knowledge was observed in individuals from Northeast Health Center, Northeast and Southeast low resource areas while desirable knowledge was observed in individuals from Viral Hepatitis Ambulatory and South Health Center. According to sociodemographic characteristics, desirable scores were more common among those with secondary education(47.1%), those who declared themselves as white(46.3%), and those who lived in houses with three individuals(25.5%). Multivariate analysis showed an association between viral hepatitis perception and type of population. CONCLUSION The results demonstrated high level of knowledge among study participants from health clinics from the Southeast region of Brazil and the importance of education programs in increasing the level of knowledge in low resource areas. | Helena Medina Cruz Jakeline Ribeiro Barbosa Jeová Keny Baima Colares Antonio Henrique Almeida de Moraes Neto Maria de Fátima Leal Alencar Francisco Inácio Bastos Jurema Corrêa da Mota Filipe Aníbal Carvalho-Costa Claudia Alexandra Pontes Ivantes Lia Laura Lewis-Ximenez Livia Melo Villar | 2018 | World Journal of Hepatology2018，10，11： | 1 |
