Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Economic evaluation of agomelatine relative to other antidepressants for treatment of major depressive disorders in Greece

Background: Major depressive disorder (MDD) constitutes an important public health problem, as it is highly prevalent in the industrialized world and it is associated with substantial economic consequences for patients, health care providers, insurance and social security organizations and employers. To conduct an economic evaluation comparing agomelatine with other commonly used alternatives for treating patients with major depressive disorder (MDD) in Greece. Methods. An existing international Markov model designed to evaluate the cost-effectiveness of agomelatine was adapted to the Greek setting. It reflects six different health states, in which patients may move on a monthly basis. The analysis was undertaken from a societal perspective. Transition probabilities, utilities and costs assigned to each health state were extracted from the published literature, government sources and expert opinion. Data reflects the year 2012 and was discounted using a rate of 3.5%. Probabilistic analysis was undertaken to deal with uncertainty. Results: Base case analyses revealed that agomelatine is a dominant therapy for MDD relative to escitalopram, fluoxetine and sertraline, and it appeared to be cost-effective compared to venlafaxine (ICER: 547/QALY). Agomelatine remained a dominant treatment against generic sertraline and fluoxetine, and it appeared to be a cost-effective alternative compared to generic venlafaxine and escitalopram (ICER: 1,446/QALY and 3,303/QALY, respectively). Excluding the indirect cost from the analysis, agomelatine remained a cost-effective alternative over all comparators. In the probabilistic sensitivity analysis agomelatine was dominant in 44.5%, 89.6%, 70.6% and 84.6% of simulated samples against branded venlafaxine, escitalopram, fluoxetine and sertraline, respectively. Conclusion: The present evaluation indicates that agomelatine is either a dominant or a cost-effective alternative relative to branded or generic alternatives, in Greece. © 2013 Maniadakis et al.; licensee BioMed Central Ltd

The Practice of Electroconvulsive Therapy in Greece

Objective: To describe the practice of electroconvulsive therapy (ECT) in Greece. Methods: A survey was conducted during the academic year 2008-2009. Electroconvulsive therapy use was investigated for 2007. All civilian institutions providing inpatient care were included. Centers that provided ECT completed a 57-item questionnaire. Centers that did not offer ECT completed a 13-item questionnaire. Results: Fifty-five (82.1%) of 67 institutions responded. Electroconvulsive therapy was offered in 18 hospitals. Only 2 of 10 university hospitals offered ECT. Overall, 137 patients were treated with 1271 sessions in 2007. Only 1.47% discontinued treatment owing to adverse events. There were no deaths. Schizophrenia was the most common diagnosis (41.3%) among those receiving ECT, followed by major depression (28.9%), bipolar depression (9.1%), catatonia (4.1%), suicidal ideation (3.3%), and schizoaffective disorder (2.5%). Physicians considered major depression (93.8%), catatonia (86.5%), schizophrenia (56.3%), and mania (50%) the most appropriate indications. Written informed consent was required in 77.8% of the institutions, whereas the rest required verbal consent. Bilateral ECT was the preferred electrode placement (88.9%). Modified ECT was used exclusively. Propofol was the preferred anesthetic (44.4%), followed by thiopental (38.9%). Seven (38.9%) of 18 hospitals used a fixed stimulus dose at first treatment. Five (27.8%) of 18 hospitals used the half-age method. Continuation/maintenance ECT was used in 33.3% of the hospitals. Outpatient ECT was seldom used. Lack of training, difficult access to anesthesiology, billing issues, and stigma were cited as the main impediments to the practice of ECT. Conclusions: Electroconvulsive therapy is practiced in moderate numbers in Greece and almost exclusively on an inpatient basis. Lack of training and lack of availability of anesthesiologists were cited as the most common obstacles to providing ECT

Theory of Mind as a potential trait marker of schizophrenia: A family study

Introduction. Although there is some evidence that Theory of Mind (ToM) deficits may be trait markers of schizophrenia it is not clear yet if ToM deficits are primary deficits, that is, to be independent of deficits in general intellectual abilities and executive function. The aim was to examine if ToM deficits may be trait markers of the illness and the effect of cognitive inhibition, general intellectual abilities and depression on ToM abilities of patients with schizophrenia and their unaffected parents. Methods. We assessed ToM abilities (first-order and second-order ToM stories, The Revised Eyes Test), cognitive inhibition (Stroop Task), general intellectual ability (Standard Progressive Matrices Test Plus) in patients with schizophrenia (N=21) and their unaffected fathers (N=21) and mothers (N=21) in comparison with healthy control families (healthy control males, N=21, healthy control fathers, N=21, healthy control mothers, N=21) Results. Patients showed deficits in first-order ToM tasks but some of these deficits were mediated by general intellectual abilities. Impairments in cognitive inhibition mediated only patients performance in The Revised Eyes Test. Patients showed deficits in second-order ToM stories independently of deficits in general intellectual abilities and cognitive inhibition. Unaffected parents did not show deficits in first-order ToM tasks, whereas they showed deficits in second-order ToM stories. However, the deficits that unaffected parents showed in second-order ToM stories were mediated by their deficits in general intellectual abilities, and there was an effect of remitted depression on the unaffected mothers performance. Conclusions. The results suggest that intact neurocognitive and general intellectual abilities are necessary in order patients and their unaffected parents to pass successfully ToM tasks. Patients and their unaffected parents show ToM deficits but these deficits are not similar. Patients show ToM deficits but these deficits seem to be a component of the pathophysiology of the illness (e.g., deficits in executive function, general intellectual abilities). © 2012 Copyright Psychology Press Ltd.link_to_subscribed_fulltex
