Article Synopsis
  • Mitochondrial disease is a rare condition currently lacking approved treatments, with sonlicromanol being a promising candidate that modifies key metabolic and inflammatory pathways.
  • A Phase 2b study was conducted to evaluate sonlicromanol's safety and efficacy in adults with a specific genetic mutation, involving both a randomized controlled trial (RCT) and a long-term extension study.
  • While the primary endpoint of the RCT didn't show significant results, there were indications of improvement in certain cognitive and emotional assessments among patients who were more affected at baseline.

In the Netherlands but also in many other countries, there is an increasing social discussion about gender identity and gender diversity, and an increasing number of children and adolescents are seeking medical help because of questions about their gender identity. The cause of this increase is still unknown. Gender questions are diverse and require an individual approach by a multidisciplinary team.

Uncertainty is increasingly recognized as a crucial phenomenon throughout medical practice. Research on uncertainty so far has been scattered across disciplines, leading to a lack of consensus about what uncertainty represents and minimal integration of knowledge obtained within isolated disciplines. Currently, a comprehensive view of uncertainty which does justice to normatively or interactionally challenging healthcare settings is lacking.

Background: Studies regarding cognitive and mental health functioning in children with mitochondrial disease (MD) are scarce, while both are important issues given their impact on QoL. Knowledge on these aspects of functioning and its relationship with disease parameters is essential to gather more insight in working mechanisms and provide recommendations for future research and patientcare. The aim of this study was to map the cognitive functioning and mental health in children with MD in relation to disease specific factors.

Background: Previous studies in patients with a mitochondrial disease (MD) highlight the high prevalence of cognitive impairments, fatigue, depression, and a lower quality of life (QoL). The relationship with biological and physiological factors remains complex. The aim of this study is to investigate the status of and interrelationships between biological and physiological functioning, cognitive functioning as well as fatigue, depression, societal participation, health perceptions, and QoL, by using the Wilson and Cleary conceptual disease model, adapted to MD.

Background: Challenges faced by children diagnosed with a rare disease or complex condition and their family members are often characterized by disease-specific complexities, such as a prolonged diagnostic process, an uncertain prognosis, and the absence of curative treatment. The psychological burden of living with a rare disease or complex condition is often understudied and may present overarching concepts that shape the general experience of having been diagnosed with a rare condition. The present study examines common needs from a comprehensive perspective combining relevant aspects from the rare disease literature in a theoretical perspective from pediatric psychology, such as a family-centred, developmental and interdisciplinary approach.

Many women born with disorders or differences of sex development (DSD) report sexual problems, in particular women who have undergone extensive genital reconstruction. Examining cognitions and emotions that hinder or promote sexuality may facilitate understanding these sexual problems and may contribute to the development of specific interventions. In this study, sexual self-concept, body image, and sexual functioning were investigated in relation to genital surgery.

Introduction: Endometriosis can cause chronic pain and subfertility thereby negatively affecting quality of life (QoL). Surgical removal of endometriosis lesions leads to improved health-related QoL, although not to the level of QoL of healthy controls. Pain intensity and cognitions regarding pain can play a crucial role in this health-related QoL following surgical treatment.

Patients with childhood, adolescent, and young adult cancer who will be treated with gonadotoxic therapies are at increased risk for infertility. Many patients and their families desire biological children but effective communication about treatment-related infertility risk and procedures for fertility preservation does not always happen. The PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the literature and developed a clinical practice guideline that provides recommendations for ongoing communication methods for fertility preservation for patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger and their families.

Gender incongruence (GI) is defined as a condition in which the gender identity of a person does not align with the gender assigned at birth. Awareness and more social acceptance have paved the way for early medical intervention about two decades ago and are now part of good clinical practice although much robust data is lacking. Medical and mental treatment in adolescents with GI is complex and is recommended to take place within a team of mental health professionals, psychiatrists, endocrinologists, and other healthcare providers.
