Adolescents' Experiences During "Boarding" Hospitalization While Awaiting Inpatient Psychiatric Treatment Following Suicidal Ideation or Suicide Attempt.

BACKGROUND: Two million adolescents experience suicidal ideation (SI) or suicide attempt (SA) annually, and they frequently present to emergency departments. Delays in transfer to inpatient psychiatric units increasingly lead to "boarding" in emergency departments and inpatient medical units. We sought to understand adolescents' perspectives during boarding hospitalizations to gain insight into helpful practices and targets for improvement. METHODS: Using convenience sampling, we conducted semistructured interviews with 27 adolescents hospitalized for SI or SA while they were awaiting transfer to an inpatient psychiatric facility. Interviews were recorded and transcribed, and the thematic analysis was organized using NVivo 11. RESULTS: Eight themes emerged: (1) supportive clinical interactions, (2) information needs, (3) repetitive inquiries, (4) safety, (5) previous hospital experiences, (6) activities and boredom, (7) physical comfort, and (8) emotions. Adolescents expressed appreciation for compassionate clinicians and for receiving information about what to expect, experienced the hospital as a safe environment, emphasized the value of staying occupied and of physical comfort, and were relieved to be receiving help to reduce their suicidal thoughts or behaviors. Reports of embarrassment and discomfort about repeated inquiries from the clinical team, comparisons with previous hospital experiences, and unanswered questions about what would occur during the planned inpatient psychiatric hospitalization were common. CONCLUSIONS: The perspectives of adolescents seeking care for SI or SA are an important source of information for health care systems seeking to improve hospital care. Clinicians can relieve distress of adolescents awaiting psychiatric hospitalization by focusing on compassionate connection, minimizing repeated inquiries, and providing complete and concrete information about treatment plans.

Biomarkers in a Taurine Trial for Succinic Semialdehyde Dehydrogenase Deficiency.

AIM: We tested the hypothesis that patients with succinic semialdehyde dehydrogenase (SSADH) deficiency on taurine would have decreased cortical excitability as measured by transcranial magnetic stimulation (TMS) and improved cognition, due to taurine's partial GABA(A and B) receptor agonist effects and rescue in the null mouse model from status epilepticus and premature lethality. METHOD: Biomarkers including neuropsychological testing, TMS, and CSF metabolites were studied in a cohort of patients on and off three months' taurine treatment. RESULTS: Seven patients (5M/2F; age range 12-33 years) were enrolled in this open-label crossover study. Baseline average full-scale IQ (FSIQ) was 44.1 (range 34-55). Of six who returned at 6-month follow-up, five completed cognitive testing (3M/2F) on therapy; average FSIQ = 43.4 (range 33-51). CSF biomarkers (n = 4 subjects) revealed elevation in taurine levels but no change in free or total GABA. Baseline cortical excitability measured with TMS agreed with previous findings in this population, with a short cortical silent period and lack of long-interval intracortical inhibition. Patients on taurine showed a decrease in cortical silent period and short-interval intracortical inhibition compared to their off taurine study. INTERPRETATION: TMS demonstrated decreased inhibition in patients on taurine, in contrast to the study hypothesis, but consistent with its failure to produce clinical or cognitive improvement. TMS may be a useful biomarker for therapy in pediatric neurotransmitter disorders.

Taurine trial in succinic semialdehyde dehydrogenase deficiency and elevated CNS GABA.

OBJECTIVES: The objective of this open-label study was primarily to assess the effect of taurine on adaptive behavior and secondarily to collect safety and tolerability data in patients with succinic semialdehyde dehydrogenase deficiency. METHODS: In the current study, subjects were titrated weekly from a starting dose of 50 mg/kg/d to a target 200 mg/kg/d, and assessed for safety, tolerability, and adaptive functioning using age-normalized Adaptive Behavior Assessment Scales. RESULTS: Eighteen patients (8 males/10 females, aged 0.5-28 years, mean 12 years) were recruited. Three subjects withdrew because of perceived lack of efficacy. One serious adverse event occurred (hospitalization for hypersomnia) on 16 g/d (200 mg/kg/d), leading to a dose-lowering paradigm with a maximum dose of 10 g/d. Results did not show clinically meaningful improvement in the adaptive domains after taurine therapy. Pre- and posttherapy adaptive scores also demonstrated no statistically significant difference (p > 0.18). CONCLUSIONS: Adaptive behavior did not improve significantly with taurine intervention. Further therapeutic clinical trials including an on-off paradigm using biomarkers are planned. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for patients with succinic semialdehyde dehydrogenase deficiency, taurine does not significantly improve adaptive behavior. The study is rated Class IV because of the absence of a control group.

Mother and child interpretations of threat in ambiguous situations: relations with child anxiety and autonomic responding.

This study examined maternal and child interpretive bias to threat (IBT) during dyadic conversation, child physiological reactivity and regulation during dyadic conversation, and maternal report of child anxiety in a community sample of 35 mothers and their 8- to 10-year-old children. Mothers and children discussed one neutral and six ambiguous scenarios, which were subsequently coded for frequency of maternal and child initiation, minimization, and expansion of threat-related themes. Child electrocardiogram data were collected during these conversations and maternal reports of child anxiety and internalizing problems were obtained. Across the sample, children initiated threat-related discussion more often than mothers. Maternal threat expansions were significantly positively correlated with child anxiety and internalizing behaviors. Maternal minimizations of threat were significantly associated with augmented child vagal tone throughout the IBT paradigm. Implications for prevention of child anxiety and directions for extending IBT research within the context of the mother-child dyad are discussed.
