Physiological sleep quality deteriorated from days when cocaine was used across the first 2 weeks of confirmed drug abstinence. In contrast, subjective reports of sleep quality remained unchanged across the same period. We postulate that this dissociation between objective and subjective sleep quality results from a cocaine-use related disruption of the sleep homeostat. Worsening sleep quality during cocaine abstinence may contribute to the risk of relapse and its treatment may offer novel therapeutic strategies for cocaine dependence.
In order to assess the role played by area V6A in visuomotor control, two adult green monkeys ( Cercopithecus aethiops) were subjected to small, bilateral lesions in the anterior bank of the parieto-occipital sulcus. Before and after the lesions, monkeys were tested for naturally designed reaching, grasping and picking-up pieces of food from various positions on a plate and from a differently oriented narrow slit. All movements were recorded with closed circuit TV and analysed offline on a single-photogram basis for defective reaching and wrist orientation. V6A lesions provoked parietal weakness, reluctance to move, and specific deficits in reaching, wrist orientation and grasping. Recovery from the observed deficits was rapid, even after a second, contralateral lesion was given, creating a bilateral lesion. Thus, together with previous anatomical and electrophysiological data, these results directly support the hypothesis that area V6A is part of the network involved in the control of reaching movements and wrist orientation.
Five cocaine-dependent individuals completed a 22-day inpatient study of sleep and cognition. Following 3 days of drug-free baseline, participants underwent 3 days of twice-daily smoked cocaine base self-administration (6 50-mg doses, 14 minutes apart), followed by 15 days of abstinence. Each morning and afternoon, the CDR repeatable, multiple-version, computerized cognitive battery (whose stability following practice has been documented) was administered. During abstinence, performance deteriorated on vigilance tasks (especially reaction time) as well as on immediate and delayed verbal recognition tasks but not on working memory tasks. Declines were most evident in the afternoon. Data suggest that abstinence can unmask cognitive deficits induced by chronic cocaine use and circadian factors may mediate their severity.
Background
Social diversity can affect healthcare outcomes in situations when access to healthcare is limited for specific groups. Although the principle of equality is one of the central topics on the agenda of the European Union (EU), its scope in the field of healthcare, however, is relatively unexplored. The aim of this study is to identify and systematically analyze primary and secondary legislation of the EU Institutions that concern the issue of access to healthcare for various minority groups. In our research, we have concentrated on three features of diversity: a) gender identity and sexual orientation, b) race and ethnicity, and c) religion or belief.
Method and materials
For the purpose of this analysis, we conducted a search of database Eur-Lex, the official website of European Union law and other public documents of the European Union, based on specific keywords accompanied by review of secondary literature. Relevant documents were examined with regard to the research topic. Our search covered documents that were in force between 13 December 2007 and 31 July 2019.
Results
Generally, the EU legal system prohibits discrimination on grounds of religion or belief, racial or ethnic origin, sex, and sexual orientation. However, with regard to the issue of non-discrimination in access to healthcare EU secondary law provides protection against discrimination only on the grounds of racial or ethnic origin and sex. The issue of discrimination in healthcare on the grounds of religion or belief, gender identity and sexual orientation is not specifically addressed under EU secondary law.
Discussion
The absence of regulations regarding non-discrimination in the EU secondary law in the area of healthcare may result from the division of competences between the European Union and the Member States. Reluctance of the Member States to adopt comprehensive antidiscrimination regulations leads to a situation, in which protection in access to healthcare primarily depends on national regulations.
Conclusions
Our study shows that EU antidiscriminatory law with regard to access to healthcare is fragmentary. Prohibition of discrimination of the level of European binding law does not fully encompass all aspects of social diversity.
The nose, once symbol of morality expressed through physical integrity, today becomes an important factor of human beauty. Rhinoplastic surgery is, both then and now, deeply pervaded with both ethics and aesthetics.
Organ transplantation is one of the most important medical achievements of the 20 th century. Kidney transplantation is the most efficient method of renal replacement therapy. The first successful kidney transplantation in human was performed in 1954 in Boston, USA. In former Yugoslavia, the first kidney transplantation was performed on April 16, 1970 in Ljubljana, Slovenia, and second one on January 30, 1971 in Rijeka, Croatia. In both cases, the mother donated kidney to the son. In the article, we describe the prerequisite conditions for this operation, the characteristics of first patients, and the impact of transplantation program on the development of the hospitals and medical schools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
