1Associations of sense of coherence with psychological distress and quality of life in inflammatory bowel disease显示文摘AIM:To investigate the relationship between sense of coherence,psychological distress and health related quality of life in inflammatory bowel disease(IBD).METHODS:This cross-sectional study enrolled a consecutive sample of 147 IBD(aged 45.1 ± 14.1 years; 57.1% female) patients recruited from a tertiary gastroenterology service.Sixty-four participants met diagnostic criteria for Crohn's disease,while eightythree patients had ulcerative colitis.Socio-demographic data(education,age,race,gender,gross monthly income and marital status),disease-related variables(illness activity,relapse rate in past 2 years,history of surgery and time since diagnosis),sense of coherence(Antonovsky's SOC scale),psychological distress symptoms(Hospital Anxiety and Depression Scale) and health-related quality of life(HRQo L; WHOQOLBref) were assessed.Hierarchical multiple regression analyses were performed to identify factors that are independently associated with psychological distress and HRQo L in patients with IBD and to provide indications for possible moderating or mediating effects.In addition,formal moderation and mediation analyses(Sobel tests) were performed to confirm potential moderators/mediators of the relationship between SOC,psychological distress symptoms and HRQoL.RESULTS:Lower SOC scores(std beta=-0.504; P < 0.001),female gender(std beta = 0.176; P = 0.021) and White race(std beta = 0.164; P = 0.033) were independently associated with higher levels of depressive symptoms,while lower levels of SOC(std beta =-0.438; P < 0.001) and higher relapse rate(std beta = 0.161; P = 0.033) were independently associated with more severe anxiety symptoms.A significant interaction between time since diagnosis and SOC was found with regard to the severity of depressive or anxiety symptoms,as the interaction term(time since diagnosis X SOC) had beta coefficients of-0.191(P = 0.009) and-0.172(P = 0.026),respectively.Lower levels of anxiety symptoms(std beta =-0.369; P < 0.001),higher levels of SOC(std beta = 0.231; P = 0.016) and non-White race(std beta =-0.229; P = 0.006),i.e.,mixed-race,which represented the reference category,were independently associated with higher levels of overall HRQoL.Anxiety symptoms were the most potent independent correlate of most aspects of HRQoL.In addition,anxiety mediated the association between SOC and satisfaction with health,as well as its relationship with physical,mental,and social relations HRQo L.Depressive symptoms also mediated the association between SOC and mental HRQoL.CONCLUSION:Our data indicated that SOC is an important construct,as it influences psychological distress and has significant albeit indirect effects on several HRQoL domains in IBD.Thiago H Freitas Elias Andreoulakis Gilberto S Alves Hesley LL Miranda Lúcia LBC Braga Thomas Hyphantis André F Carvalho 2015World Journal of Gastroenterology2015,21,21:10
2Liquid chromatographic methods for determination of the new antiepileptic drugs stiripentol, retigabine, rufinamide and perampanel: A comprehensive and critical review显示文摘The new antiepileptic drugs perampanel,retigabine,rufinamide and stiripentol have been recently approved for different epilepsy types.Being them an innovation in the antiepileptics armamentarium,a lot of investigations regarding their pharmacological properties are yet to be performed.Besides,considering their broad anticonvulsant activities,an extension of their therapeutic indications may be worthy of investigation,especially regarding other seizure types as well as other central nervous system disorders.Although different liquid chromatographic(LC)methods coupled with ultraviolet,fluorescence,mass or tandem-mass spectrometry detection have already been developed for the determination of perampanel,retigabine,rufinamide and stiripentol,new and more cost-effective methods are yet required.Therefore,this review summarizes the main analytical aspects regarding the liquid chromatographic methods developed for the analysis of perampanel,retigabine(and its main active metabolite),rufinamide and stiripentol in biological samples and pharmaceutical dosage forms.Furthermore,the physicochemical and stability properties of the target compounds will also be addressed.Thus,this review gathers,for the first time,important background information on LC methods that have been developed and applied for the determination of perampanel,retigabine,rufinamide and stiripentol,which should be considered as a starting point if new(bio)analytical techniques are aimed to be implemented for these drugs.Sara Meirinho Marcio Rodrigues Ana Fortuna Amílcar Falcao Gilberto Alves 2021Journal of Pharmaceutical Analysis2021,11,4:2

7Genotype-environment interaction in Cordia trichotoma(Vell.)Arráb.Ex Steud.progenies in two different soil conditions显示文摘Investment in silvicultural techniques is noticeably lacking,especially in breeding programs for non-conventional wood species.Studying genotype×environment interaction(G×E)is essential to the development of breeding programs.Thus,this study aimed to estimate genetic diversity of and the effects of G×E interaction on two progeny tests of Cordia trichotoma,including the estimation of genetic gain and genetic diversity after selection.For the experiment,30 progenies of C.trichotoma were tested at two sites with differing soil textures.Diameter at breast height(1.30 m above soil surface,dbh-cm),total height,diameter at 30 cm from the soil,first branch height,and survival were all monitored for four years.Statistical deviance,best linear unbiased estimator,and harmonic mean of relative performance of genetic values(MHPRVG)were all calculated to predict breeding values,estimate genetic parameters,and analyze deviance.All quantified traits varied significantly among progenies by soil type,with greatest variation recorded for genetic variability.Heritability of the progenies led to predictions of genetic gain,ranging from 7.73 to 15.45%,for dbh at four years of age.The calculated decrease in genetic diversity after selection showed that this parameter should be monitored in subsequent breeding cycles.G×E was low for all tests.The best-performing progenies proved most stable and best adapted to the different environmental conditions tested.Wanderley dos Santos Bruno Marchetti de Souza Daniele Fernanda Zulian Gilberto Terra Ribeiro Alves João Bosco Vasconcellos Gomes Mário Luiz Teixeira de Moraes Valderês Aparecida de Sousa Ananda Virginia de Aguiar 2022Journal of Forestry Research2022,33,1:0
