[What do psychologists think about classificatory diagnostics: the WHO-IUPsyS-survey in Germany and Switzerland in preparation for the ICD-11]. / Wie sehen Psychologen die klassifikatorische Diagnostik: WHO-IUPsyS-Survey in Deutschland und der Schweiz zur Vorbereitung der ICD-11.

AIM OF THE STUDY: For the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11) attitudes of psychologists towards classificatory diagnostics should be considered. METHOD: A survey was conducted via the Internet in 22 countries. 1985 psychologists participated with N=170 from Germany and N=37 from Switzerland. RESULTS: The German participants preferred the ICD. Classificatory diagnostics should inform on treatment as well as serve for communication. The majority argued for a flexible use and guidance towards strict criteria. In contrast to respondents from other countries, a functional status as part of the diagnostic criteria was not considered but in line with them, a dimensional component was endorsed. CONCLUSION: Responses of the German psychologists partially differ to those of participants from other countries. Differences and implications are discussed.

Psychologists' perspectives on the diagnostic classification of mental disorders: results from the WHO-IUPsyS Global Survey.

This study examined psychologists' views and practices regarding diagnostic classification systems for mental and behavioral disorders so as to inform the development of the ICD-11 by the World Health Organization (WHO). WHO and the International Union of Psychological Science (IUPsyS) conducted a multilingual survey of 2155 psychologists from 23 countries, recruited through their national psychological associations. Sixty percent of global psychologists routinely used a formal classification system, with ICD-10 used most frequently by 51% and DSM-IV by 44%. Psychologists viewed informing treatment decisions and facilitating communication as the most important purposes of classification, and preferred flexible diagnostic guidelines to strict criteria. Clinicians favorably evaluated most diagnostic categories, but identified a number of problematic diagnoses. Substantial percentages reported problems with crosscultural applicability and cultural bias, especially among psychologists outside the USA and Europe. Findings underscore the priority of clinical utility and professional and cultural differences in international psychology. Implications for ICD-11 development and dissemination are discussed.

Synthesis and CYP26A1 inhibitory activity of novel methyl 3-[4-(arylamino)phenyl]-3-(azole)-2,2-dimethylpropanoates.

The role of all-trans-retinoic acid (ATRA) in the development and maintenance of many epithelial and neural tissues has raised great interest in the potential of ATRA and related compounds (retinoids) as pharmacological agents, particularly for the treatment of cancer, skin, neurodegenerative and autoimmune diseases. The use of ATRA or prodrugs as pharmacological agents is limited by a short half-life in vivo resulting from the activity of specific ATRA hydroxylases, CYP26 enzymes, induced by ATRA in liver and target tissues. For this reason retinoic acid metabolism blocking agents (RAMBAs) have been developed for treating cancer and a wide range of other diseases. The synthesis, CYP26A1 inhibitory activity and molecular modeling studies of novel methyl 3-[4-(arylamino)phenyl]-3-(azole)-2,2-dimethylpropanoates are presented. From this series of compounds clear SAR can be derived for 4-substitution of the phenyl ring with electron-donating groups more favourable for inhibitory activity. Both the methylenedioxyphenyl imidazole (17, IC(50) = 8 nM) and triazole (18, IC(50) = 6.7 nM) derivatives were potent inhibitors with additional binding interactions between the methylenedioxy moiety and the CYP26 active site likely to be the main factor. The 6-bromo-3-pyridine imidazole 15 (IC(50) = 5.7 nM) was the most active from this series compared with the standards liarozole (IC(50) = 540 nM) and R116010 (IC(50) = 10 nM).

Innovations and changes in the ICD-11 classification of mental, behavioural and neurodevelopmental disorders.

Following approval of the ICD-11 by the World Health Assembly in May 2019, World Health Organization (WHO) member states will transition from the ICD-10 to the ICD-11, with reporting of health statistics based on the new system to begin on January 1, 2022. The WHO Department of Mental Health and Substance Abuse will publish Clinical Descriptions and Diagnostic Guidelines (CDDG) for ICD-11 Mental, Behavioural and Neurodevelopmental Disorders following ICD-11's approval. The development of the ICD-11 CDDG over the past decade, based on the principles of clinical utility and global applicability, has been the most broadly international, multilingual, multidisciplinary and participative revision process ever implemented for a classification of mental disorders. Innovations in the ICD-11 include the provision of consistent and systematically characterized information, the adoption of a lifespan approach, and culture-related guidance for each disorder. Dimensional approaches have been incorporated into the classification, particularly for personality disorders and primary psychotic disorders, in ways that are consistent with current evidence, are more compatible with recovery-based approaches, eliminate artificial comorbidity, and more effectively capture changes over time. Here we describe major changes to the structure of the ICD-11 classification of mental disorders as compared to the ICD-10, and the development of two new ICD-11 chapters relevant to mental health practice. We illustrate a set of new categories that have been added to the ICD-11 and present the rationale for their inclusion. Finally, we provide a description of the important changes that have been made in each ICD-11 disorder grouping. This information is intended to be useful for both clinicians and researchers in orienting themselves to the ICD-11 and in preparing for implementation in their own professional contexts.

Core competencies in clinical neuropsychology training across the world.

OBJECTIVE: This work aimed to review main competency requirements from training models in countries with well-established specialties in clinical neuropsychology and to extract core competencies that likely will apply to clinical neuropsychologists regardless of regional and cultural context. METHOD: We reviewed standards for post-graduate training in clinical neuropsychology from countries in Europe, Australia, and North America based on existing literature, presentations at international conferences, and from description of the training models from national psychological or neuropsychological associations. RESULTS: Despite differences, the reviewed models share similar core competencies considered necessary for a specialty in clinical neuropsychology: (1) In-depth knowledge of general psychology including clinical psychology (post-graduate level), ethical, and legal standards. (2) Expert knowledge about clinically relevant brain-behavioral relationships. (3) Comprehensive knowledge about, and skills in, related clinical disciplines. (4) In-depth knowledge about and skills in neuropsychological assessment, including decision-making and diagnostic competency according to current classification of diseases. (5) Competencies in the area of diversity and culture in relation to clinical neuropsychology. (6) Communication competency of neuropsychological findings and test results to relevant and diverse audiences. (7) Knowledge about and skills in psychological and neuropsychological intervention, including treatment and rehabilitation. CONCLUSIONS: All the models have undergone years of development in accordance with requirements of national health care systems in different parts of the world. Despite differences, the common core competency requirements across different regions of the world suggest generalizability of these competencies. We hope this summary can be useful as countries with less established neuropsychology training programs develop their models.

Neuropsychology in South Africa: confronting the challenges of specialist practice in a culturally diverse developing country.

OBJECTIVE: This was an invited paper on the history and current status of neuropsychology in South Africa. METHOD: Information was gathered from literature searches, personal communication, and the authors' experiences while occupying relevant professional and academic positions for over 30 years. RESULTS: Since its origins in the 1950s, the development of neuropsychology in South Africa has faced numerous challenges, against a background of extreme sociocultural and socioeconomic disparity in the country that is on-going. The creation of the South African Clinical Neuropsychological Society in the 1980s, a credentialing and training body, gave impetus to the discipline. In the absence of a neuropsychology category within the South African professional framework, university instruction has been ad hoc with vastly different levels of competency depending on the institution involved. The small number of practitioners and/or academics involved in neuropsychology includes mainly masters, and some doctoral level psychologists registered in clinical, counseling or educational categories. A prime emphasis of neuropsychological research has been local norming of psychometric tests to facilitate valid assessment practices in the country. South Africa is on the cusp of achieving a hard-won neuropsychology professional register. It is anticipated that this development will provide impetus to the discipline by promoting training programs, the creation of neuropsychology posts, wider service delivery, and increased research funding. CONCLUSIONS: Despite significant challenges in a culturally diverse, developing country, neuropsychology has evolved sufficiently to warrant the creation of a separate category in the professional framework. This development will facilitate training, research, and services in the country.

Early Decompression following Cervical Spinal Cord Injury: Examining the Process of Care from Accident Scene to Surgery.

Early decompression may improve neurological outcome after spinal cord injury (SCI), but is often difficult to achieve because of logistical issues. The aims of this study were to 1) determine the time to decompression in cases of isolated cervical SCI in Australia and New Zealand and 2) determine where substantial delays occur as patients move from the accident scene to surgery. Data were extracted from medical records of patients aged 15-70 years with C3-T1 traumatic SCI between 2010 and 2013. A total of 192 patients were included. The median time from accident scene to decompression was 21 h, with the fastest times associated with closed reduction (6 h). A significant decrease in the time to decompression occurred from 2010 (31 h) to 2013 (19 h, p = 0.008). Patients undergoing direct surgical hospital admission had a significantly lower time to decompression, compared with patients undergoing pre-surgical hospital admission (12 h vs. 26 h, p < 0.0001). Medical stabilization and radiological investigation appeared not to influence the timing of surgery. The time taken to organize the operating theater following surgical hospital admission was a further factor delaying decompression (12.5 h). There was a relationship between the timing of decompression and the proportion of patients demonstrating substantial recovery (2-3 American Spinal Injury Association Impairment Scale grades). In conclusion, the time of cervical spine decompression markedly improved over the study period. Neurological recovery appeared to be promoted by rapid decompression. Direct surgical hospital admission, rapid organization of theater, and where possible, use of closed reduction, are likely to be effective strategies to reduce the time to decompression.
