Abstract
Genetic counselling education and training in Europe spans a continuum of 30 years. More master programs are opening due the demand for qualified genetic counselors. This report describes the evolution of training in Europe and the current state of genetic counselling training programs. Directors of master programs in Europe were invited to complete an online survey describing their program, including year of commencement, course duration, number of students and frequency of intake and number graduating. Results of the survey were presented at a closed meeting at the European Society of Human Genetics conference in 2022 along with a facilitated stakeholder engagement session in which 19 professionals participated to understand the challenges in delivering genetic counselling education in Europe. A total of 10 active programs exists in Europe with the first training program starting in 1992. The majority of training programs have a 2-year duration, with just over half of programs having an annual intake of students. Up to May 2022, 710 students have graduated from genetic counseling training programs across Europe. Of these, 670 students graduated from European Board of Medical Genetics-registered programs. Arranging clinical placements, clinical and counseling supervision of students, research collaboration for MSc research projects and incorporating genomics into the curriculum were identified as current challenges for genetic counseling education. Genetic counseling is still a developing profession in Europe and this historical and current view of the European genetic counselor pathways, allows for educational and professional standards to be examined as the profession evolves into the future.

Abstract
In recent decades, genetics has undergone important technological advances. The rapid shift to genomics has made a strong impact on health systems around the world. In Portugal, this huge increase in consultations and typologies of genetic tests has joined the serious limitations of the few existing genetics services. The following study aims to characterize the current state of the network of genetics services in Portugal regarding its functioning, main challenges, and opportunities. Five semi-structured interviews were conducted, corresponding to 83.33% of the directors of the public genetics services of the National Health Service. Four thematic categories emerged from the analysis: (1) specialty and technical developments, (2) structural difficulties, (3) potentialities, and (4) future directions. The developments are due to the emergence of more comprehensive genetic applications, specific protocols and patient referral standards, and accreditation of services. The main difficulties encountered in the functioning of the services were difficulty in obtaining funding, lack of human resources, service overload, and lack of exclusive time for training and research. The potentialities mentioned were the establishment of multidisciplinary teams and the best articulation with specialists from other areas. Among the various future directions pointed out, better management of patients' waiting lists, the importance of research, the simplification of test request procedures, and the creation of specialized units inside the genetic services, were reported. The results showed several gaps in the practice of medical genetics that should be addressed with the development of public policies for the recognition and restructuring of medical genetics in health care.

Abstract
The main objective of our study was to explore whether, and to what extent, genetic counselors' characteristics impact on their tasks in practice. Specifically, we explored the complementariness between genetic counselors and medical geneticists and therefore looked at the most relevant tasks of genetic counselors, according to genetic counselors themselves and according to the medical geneticists they work with. A total of 104 genetic counselors and 29 medical geneticists from 15 countries completed a purposefully designed questionnaire. Results showed that most genetic counselors in Europe perform similar tasks, irrespective of their backgrounds. When looking at the factors influencing genetic counselors' roles data showed that the type of tasks performed by genetic counselors is associated with the years of experience in the field, not with their background or education. Of particular interest was the consensus between genetic counselors and medical geneticists regarding the genetic counselor's role. Not surprisingly, tasks with more psychosocial implications were seen as genetic counselors' eligibility while tasks with more medical implications were seen as medical geneticists' attribution. Our study shows that most genetic counselors work in tune with international recommendations and seem to be supportive of multidisciplinary teams. Corroborating our data with previous research, we discuss potential implications for practice and training in genetic counseling.

Abstract
The need for appropriately trained genetic counsellors to support genetic healthcare is now acknowledged. However, while programmes for education of genetic counsellors exist in a number of countries, these do not conform to any specific international standards. As genetic techniques, educational standards and professional standards have been evolved, and with increasing mobility of genetic counsellors, it is of great importance to have some comparison of education and training between different countries. This systematic review was conducted to determine the components of educational programmes for genetic counsellors worldwide that have been published in peer-reviewed literature. Databases were searched for studies published in English from 2000 to 2014 related to the topic. We identified 406 potential papers, of these, 11 studies met the inclusion criteria. The findings indicate that, in most cases, the theoretical components of genetic counsellor programmes conform to the recommendations and requirements of relevant professional bodies. However, clinical preparation of genetic counsellors in real-life professional practice settings seems to be less well addressed as this is essential to ensure genetic counsellors are able to provide safe patient care after graduation. Further work to gain agreement internationally on genetic counsellor education is needed.

Abstract
Quality assessment of genetic counseling practice for improving healthcare is a challenge for genetic services worldwide; however, there is scarce literature regarding quality issues in genetic counseling in the context of presymptomatic testing for late-onset neurological diseases (Paneque et al. 2012) The aims of this qualitative study were to: (1) explore the views of professionals' who provide genetic counseling services for presymptomatic testing for late-onset neurological diseases regarding relevant quality indicators for counseling practice; and (2) examine current assessment of such counseling practice for Portuguese genetic services. Quality indicators are a means of measuring either the process or outcomes of patient services, with the aim of evaluating and improving quality of care (Mainz 2003). In this study, we defined quality indicators as measurable outcomes of the counseling process that may reflect good professional practice and desirable end-term effects. We undertook interviews with 18 genetic health professionals (85 % of all genetic counseling professionals involved) from the major genetic services in Portugal. Results indicate that professionals valued some core components of genetic counseling, including providing information and decision-making support, informing the consultand about the genetic counseling protocol, as well as exploring motivations, expectations for test results, consequent anticipated life changes, psychosocial adjustment, and personal and familial experience with the disease. Professionals were not, however, able to clearly elucidate quality indicators for effective practice and some reported they had not reflected on that topic before. Professionals also reported specific challenges in their practice, such as ambiguity of the health/illness status and affirming consultands' autonomy. Results of the study have revealed a lack of knowledge about quality indicators and tools to assess counseling practice. A credible set of quality indicators for presymptomatic testing is required as a foundation for the development of specific tools.

Abstract
Having reported the world's highest prevalence of spinocerebellar ataxia type 2 (SCA2), health professionals in Cuba developed a program for the predictive testing of this condition. Between February 2001 and December 2011, a total of 1050 individuals requested their inclusion in the presymptomatic testing (PST) program. Their medical records were retrospectively analyzed in the present descriptive study. A total of 768 participants completed the protocol, 204 withdrew and 78 were excluded. The PST uptake was 24.91%. Females predominated and 70.96% had negative test results. Their main motivations were risk assessment in their descendants, physical and psychological preparation to cope with the disease and planning for the future. The profile of Cuban participants in the predictive testing program is similar to the one reported for other programs all over the world, nevertheless the genetic counseling practice at the community level is a distinctive aspect, which is valuable in providing at-risk individuals with wide and proper knowledge before their testing inclusion request. The SCA2 predictive testing program has high uptake rates and is renowned in our population. Future research is needed to assess the long-term psychological impact in the participants, their partners and relatives.

Abstract
Machado-Joseph disease [MJD, also spinocerebellar ataxia type 3 (SCA3)] and familial amyloid polyneuropathy type I (FAP-I or ATTR V30M) are neurodegenerative disorders, inherited in an autosomal dominant fashion, which have a high prevalence in Portugal, probably due to a founder effect. MJD and FAP-I are late-onset diseases, with symptoms emerging usually during adulthood. CGPP, which is the national reference centre for these disorders, has a genetic lab that offers diagnostic, pre-symptomatic and prenatal testing and an outpatient clinic to counsel and follow relatives at risk for hereditary ataxias, FAP-I and Huntington disease (HD). The present work is a review of our 10-year experience with psychological counselling of individuals at risk for MJD and FAP-I. Persons at risk for FAP-I may show a better response to pre-symptomatic testing than those who are at risk for MJD and HD because of the availability of liver transplantation, which may improve their health and life expectancy. Psychological well-being and specific distress of MJD and FAP-I test applicants, before undergoing genetic testing (baseline level) and 3 to 6 months after disclosure of test results, have shown a low level of change, both in identified carriers and non-carriers. A major goal of psychological characterization of at-risk individuals for MJD and FAP-I is to determine the factors that influence the uptake of genetic testing.

Abstract
Compounds of rhodium(I) and rhodium(III) that contain ancillary hydrotris(pyrazolyl)borate ligands (Tp') react with monodentate and bidentate tertiary phosphanes in a step-wise manner, with incorporation of P-donor atoms and concomitant replacement of the Tp' pyrazolyl rings. Accordingly, [Rh(kappa3-TpMe2)(C2H4)(PMe3)] (1b), converts initially into [Rh(kappa2-TpMe2)-(PMe3)2] (3), and then into [Rh(kappa1-TpMe2)-(PMe3)3] (2) upon interaction with PMe3 at room temperature, in a process which can be readily reversed under appropriate experimental conditions. Full disengagement of the Tp' ligand is feasible to give Tp' salts of rhodium(I) complex cations, for example, [Rh(CO)(dppp)2]-[TpMe2,4-Cl] (5; dppp = Ph2P(CH2)3PPh2), or [Rh(dppp)2][TpMe2,4-Cl] (6). Bis(hydride) derivatives of rhodium(III) exhibit similar substitution chemistry, for instance, the neutral complex [Rh(Tp)-(H)2(PMe3)] reacts at 20 degrees C with an excess of PMe3 to give [Rh(H)2-(PMe3)4][Tp] (9b). Single-crystal X-ray studies of 9b, conducted at 143 K, demonstrate the absence of bonding interactions between the [Rh(H)2(PMe3)4]+ and Tp ions, the closest Rh...N contact being at 4.627 A.

Abstract
Hydroperoxide lyases (HPLs) catalyze the cleavage of fatty acid hydroperoxides to aldehydes and oxoacids. These volatile aldehydes play a major role in forming the aroma of many plant fruits and flowers. In addition, they have antimicrobial activity in vitro and thus are thought to be involved in the plant defense response against pest and pathogen attack. An HPL activity present in potato leaves has been characterized and shown to cleave specifically 13-hydroperoxides of both linoleic and linolenic acids to yield hexanal and 3-hexenal, respectively, and 12-oxo-dodecenoic acid. A cDNA encoding this HPL has been isolated and used to monitor gene expression in healthy and mechanically damaged potato plants. HPL gene expression is subject to developmental control, being high in young leaves and attenuated in older ones, and it is induced weakly by wounding. HPL enzymatic activity, nevertheless, remains constant in leaves of different ages and also after wounding, suggesting that posttranscriptional mechanisms may regulate its activity levels. Antisense-mediated HPL depletion in transgenic potato plants has identified this enzyme as a major route of 13-fatty acid hydroperoxide degradation in the leaves. Although these transgenic plants have highly reduced levels of both hexanal and 3-hexenal, they show no phenotypic differences compared with wild-type ones, particularly in regard to the expression of wound-induced genes. However, aphids feeding on the HPL-depleted plants display approximately a two-fold increase in fecundity above those feeding on nontransformed plants, consistent with the hypothesis that HPL-derived products have a negative impact on aphid performance. Thus, HPL-catalyzed production of C6 aldehydes may be a key step of a built-in resistance mechanism of plants against some sucking insect pests.

Abstract
The bis(ethylene) Rh species TpMe2Rh(C2H4)2(1*) (TpMe2 = tris(3,5-dimethyl-1-pyrazol-1-yl)hydroborate) has been obtained from [RhCl(C2H4)2]2 and KTpMe2. Complex 1* easily decomposes in solution to give mainly the butadiene species TpMe2Rh(eta74-C4H6). In the solid state its thermal decomposition follows a different course and the allyl TpMe2RhH(syn-C3H4Me) is cleanly obtained as a mixture of exo and endo isomers. The complexes Tp'Rh(C2H4)2 (Tp' = Tp, TpMe2) afford the monosubstituted species Tp'Rh(C2H4)(PR3) upon reaction with PR3 but react differently with L = CO or CNR: the Tp compound gives dinuclear [TpRh]2(mu-L)3 complexes, while, in the case of 1*, TpMe2Rh(C2H4)(L) species are obtained. The ethylene ligand of complexes TpMe2Rh(C2H4)(PR3) is labile, and several peroxo compounds of composition TpMe2Rh(O2)(PR3) have been isolated by their reaction with O2. All the mononuclear Rh(I) complexes are formulated as 18e- trigonal bipyramidal species on the basis of IR and NMR spectroscopic studies. A series of dihydride complexes of Rh(III) of formulation Tp'RhH2(PR3) have been prepared by the hydrogenation of the corresponding ethylene derivatives. Complexes [TpRh]2(mu-CNCy)3, TpMe2Rh(C2H4)(PEt3), and TpMe2Rh(O2)(PEt3) have been further characterized by X-ray diffraction studies.

Abstract
INTRODUCTION The prevalence of hereditary ataxia in Holguín, Cuba, is 43 per 100,000 inhabitants, but in some regions reaches 503 per 100,000 inhabitants, a figure never previously recorded in the international literature. OBJECTIVES To evaluate the part played by non-cerebellar structures and vias in causing some of the clinical signs of the disorder by means of clinico-electro physiological correlation. PATIENTS AND METHODS A neurological examination, peripheral nerve conduction studies and somato-sensorial evoked potentials of the median and posterior tibial nerves were done in 70 patients with type 2 spinocerebellar ataxia. RESULTS The commonest clinical signs were ataxia on walking, dysarthria, dysmetria and adiadochokinesia. Correlation analysis showed that the variable most significantly correlated with the degree of ataxia and Romberg's sign was latency of the P40 component, whilst tendon reflexes were best correlated with H reflex latency. However, the duration of the disease was not found to have statistical correlation. CONCLUSIONS These results suggest that degeneration of long peripheral nerves and sensory paths contributes to the degree of ataxia and other clinical signs. At present no correlation has been found between the duration of the illness and increasing electrophysiological changes, and therefore seems not to have a major effect on neurodegenerative mechanisms.

Abstract
Isolated hydrotris(pyrazolyl)borate anions Tp' were obtained as salts of metal complex cations (see picture) by the displacement of Rh-coordinated kappa(3)-N,N',N"-Tp' by PMe(3) (Tp'=Tp and Tp(Me2)). With [(kappa(3)-Tp(Me2))Rh(C(2)H(4))(2)], stepwise diplacement of the Tp(Me2) ligand allowed the isolation of complexes exhibiting the kappa(2)- Tp(Me2) and kappa(1)-Tp(Me2) coordination modes.
