Declining free thyroxine levels over time in irradiated childhood brain tumor survivors

Objective: The incidence of cranial radiotherapy (cRT)–induced central hypothyroidism (TSHD) in childhood brain tumor survivors (CBTS) is reported to be low. However, TSHD may be more frequent than currently suspected, as its diagnosis is challenging due to broad reference ranges for free thyroxine (FT4) concentrations. TSHD is more likely to be present when FT4 levels progressively decline over time. Therefore, we determined the incidence and latency time of TSHD and changes of FT4 levels over time in irradiated CBTS. Design: Nationwide, 10-year retrospective study of irradiated CBTS. Methods: TSHD was defined as ‘diagnosed’ when FT4 concentrations were below the reference range with low, normal or mildly elevated thyrotropin levels, and as ‘presumed’ when FT4 declined ≥ 20% within the reference range. Longitudinal FT4 concentrations over time were determined in growth hormone deficient (GHD) CBTS with and without diagnosed TSHD from cRT to last follow-up (paired t-test). Results: Of 207 included CBTS, the 5-year cumulative incidence of diagnosed TSHD was 20.3%, which occurred in 50% (25/50) of CBTS with GHD by 3.4 years (range, 0.9–9.7) after cRT. Presumed TSHD was present in 20 additional CBTS. The median FT4 decline in GH-deficient CBTS was 41.3% (P < 0.01) to diagnosis of TSHD and 12.4% (P = 0.02) in GH-deficient CBTS without diagnosed TSHD. Conclusions: FT4 concentrations in CBTS significantly decline over time after cRT, also in those not diagnosed with TSHD, suggesting that TSHD occurs more frequently and earlier than currently reported. The clinical relevance of cRT-induced FT4 decline over time should be investigated in future studies

Anticipating the future of the child and family in pediatric palliative care: a qualitative study into the perspectives of parents and healthcare professionals

Preparing for future scenarios in pediatric palliative care is perceived as complex and challenging by both families and healthcare professionals. This interpretative qualitative study using thematic analysis aims to explore how parents and healthcare professionals anticipate the future of the child and family in pediatric palliative care. Single and repeated interviews were undertaken with 42 parents and 35 healthcare professionals of 24 children, receiving palliative care. Anticipating the future was seen in three forms: goal-directed conversations, anticipated care, and guidance on the job. Goal-directed conversations were initiated by either parents or healthcare professionals to ensure others could align with their perspective regarding the future. Anticipated care meant healthcare professionals or parents organized practical care arrangements for future scenarios with or without informing each other. Guidance on the job was a form of short-term anticipation, whereby healthcare professionals guide parents ad hoc through difficult situations. Conclusion: Anticipating the future of the child and family is mainly focused on achievement of individual care goals of both families and healthcare professionals, practical arrangements in advance, and short-term anticipation when a child deteriorates. A more open approach early in disease trajectories exploring perspectives on the future could allow parents to anticipate more gradually and to integrate their preferences into the care of their child.What is Known:• Anticipating the future in pediatric palliative care occurs infrequently and too late.What is New:• Healthcare professionals and parents use different strategies to anticipate the future of children receiving palliative care, both intentionally and unwittingly. Strategies to anticipate the future are goal-directed conversations, anticipated care, and guidance on the job.• Parents and healthcare professionals are engaged to a limited extent in ongoing explorative conversations that support shared decision-making regarding future care and treatment
