Based on a constructivist worldview, this phenomenological investigation followed a qualitative approach by conducting eight interviews and analyzing qualitative data. The main results suggest that the psychosocial experience of the members of families interviewed is marked by: (a) a delayed awareness of the family disease (viz., in adulthood), (b) psychosocial impacts (viz., emotional and other impacts related to work, parenting, caregiving) experienced and anticipated in an adult phase of the life cycle, and (c) the use of approach strategies (e.g., seeking information about A-ATTRv-PN and seeking social support) and/or avoidance strategies (e.g., avoiding seeking information and talking to others about the condition) with a view to accommodating A-ATTRv-PN in personal and family life. These results differ from the life trajectories of members of Portuguese families with A-ATTRv-PN described previously and extend previous scientific evidence on the psychosocial experience of members of families where the disease typically appears late, contributing to further study on this topic and to the optimization of genetic counseling practices and health policies that respond to the psychosocial needs of members of Portuguese families with late onset of the condition.

{"title":"Genetic counselling for psychiatric conditions: exploring current perceptions of family physicians and psychiatrists in Portugal.","authors":"B Ribeiro, I Homem de Melo, A Sequeira, R Moldovan, M Paneque","doi":"10.1007/s12687-025-00774-7","DOIUrl":"https://doi.org/10.1007/s12687-025-00774-7","url":null,"abstract":"<p><p>Genetic counselling emerged as a specialized healthcare discipline in the 1960s, and since then, various sub-specialties have developed globally, namely and more recently, psychiatric genetic counselling. This study provides a pioneering exploration of family physicians and psychiatrists' perceptions regarding genetic counselling provision and its potentialities in the context of psychiatric illnesses in Portugal. A qualitative methodology with semi-structured interviews was used. Among the participants, five were family physicians, and six were psychiatrists. Thematic analysis revealed three themes: (1) the role of genetics in healthcare, (2) barriers to psychiatric genetic counselling implementation, and (3) perceived benefits associated with its implementation. Results show that while the importance of genetics in psychiatric disorders is acknowledged, there is low literacy about genetic counselling practice from the professional groups interviewed. Also, the availability and mainstreaming of genetic testing seem to influence how genetic counselling is perceived and utilized. There is a perceived need for training and guidelines that foster the dissemination of genetics into healthcare, specifically mental healthcare. A holistic and patient-centred approach is considered essential in managing psychiatric disorders and, by extension, in psychiatric genetic counselling, as it addresses both medical and psychosocial factors. Although psychiatrists and family physicians are keen to integrate psychiatric genetic counselling into their patients' care, it seems that certain fundamental challenges still persist in genetic healthcare provision. Future research should contribute for a more comprehensive evaluation of the readiness for psychiatric genetic counselling implementation in the country.</p>","PeriodicalId":46965,"journal":{"name":"Journal of Community Genetics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143450447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their median (IQR) HCDe was 5 (6) years and did not differ across diseases. Over the years, the number of annual PSC diagnoses became similar to that of SC. Better schooling and recurrent familial cases were associated with shorter HCDe, but the strongest effect on HCDe was related to PGT: in 33 PSC who converted and came to healthcare, HCDe was of 1 year (p < 0.0001, MW). HCDe was large in all TNRED studied. Parameters related to better access to information, especially PGT, improved HCDe.

A documentary review on access to PD treatment within Brazil's Unified Health System (SUS) was conducted. This included health technology assessments (HTA) and regulatory decisions from Brazilian and international agencies. Data on the dispensing of alglucosidase alfa from the Brazilian Outpatient Information System (SIA/SUS; Jan 2020-May 2024) were analyzed and compared to previous budget impact estimates. Only alglucosidase alfa is covered by the SUS, and exclusively for Infantile-onset Pompe Disease (IOPD). Projections for vial usage in the SUS were overestimated. Key drivers of access include Ministry of Health policies, HTA recommendations, judiciary decisions, and industry actions.

Most cases have early manifestations (in childhood and adolescence), and just a small fraction (around 5%) has specific therapies available. Nevertheless, appropriate management measures contribute to improve the quality of life of patients and families. They affect up to 3.5-5.9% of the world's population and are recently attracting attention from international agencies such as the United Nations and the World Health Organization. In Brazil, a condition is considered rare when there are no more than 65 people affected in each 100,000 inhabitants and it is estimated that around 12 million people in the country may present one of these conditions, which represents a significant burden to the family and to the health care system. Despite concrete advances observed in the last decades, there are still significant unmet needs for persons living with rare diseases in Brazil. With the main aim of shortening the journey of patients with rare diseases in Brazil, we envisioned a model that involves comprehensive clinical and laboratorial multiprofessional evaluations, with intensive use of telemedicine and genomics. The model includes a strong activity in education, training and research, and has several parallel initiatives (biobank, registry, undiagnosed disease program, information services, extramural diagnostic support), in addition to strategic partnerships, that make the overall project stronger. This report describes the system in place at the pilot unit of Casa dos Raros (that started activities in 2023, in Porto Alegre, Brazil) and the stimulating preliminary results, which indicate a significant reduction in the diagnostic journey.

Conducted at a genetic clinic in India, the study employed a qualitative methodology guided by COREQ guidelines, using semi-structured interviews to explore the interplay of individual beliefs, healthcare provider practices, and systemic healthcare inefficiencies. The interviews were transcribed and analyzed using a combination of content analysis and grounded theory, which allowed for the identification of recurrent themes and emerging ideas. The study found that strong religious and cultural beliefs often led families to disregard medical advice, contributing to the recurrence of genetic conditions. Additionally, significant gaps in healthcare provider knowledge and inadequate reproductive counseling were identified as critical barriers to timely diagnosis and prevention of recurrence. Another major theme was the inherent complexities of genetic diseases and genetic testing, where variable expression of conditions, delayed symptom onset, and limitations of genetic tests themselves often prevented early diagnosis and intervention. This research highlights the need for improved genetic literacy among healthcare providers, culturally sensitive counseling, and better integration of genetic services into the broader healthcare system. By addressing these barriers, the risk of recurrence can be significantly reduced, improving patient outcomes and family well-being.
