The importance of suicide risk assessment in patients affected by neurofibromatosis

Investigating psychiatric morbidity, hopelessness and suicide risk in patients with 22q11.2 deletion syndrome: a case-control study

BACKGROUND

The psychiatric phenotype of the 22q11.2 deletion syndrome (22q11DS) has been largely described.

OBJECTIVES

With a case-control study design, we now compared a sample of 22q11DS patients with a psychiatric diagnosis with a sample of psychiatric patients without 22q11DS to investigate possible differences between groups for depression severity, hopelessness, and suicide. Patients with 22q11DS were divided into two groups according to the levels of hopelessness to evaluate the relationship between hopelessness and the severity of the 22q11DS, the level of disability, functional impairment, physical frailty, and autonomy level.

RESULTS

Results showed that suicide risk evaluated with the C-SSRS was similar in the two groups of patients and that a diagnosis of 22q11DS does not appear to be a risk factor for suicide; however, 22q11DS patients had more severe hopelessness. Patients with a more severe clinical presentation and worse overall functioning have higher levels of depressive symptoms and hopelessness.

CONCLUSIONS

The results suggest the need to assess and monitor psychiatric symptoms in patients with 22q11DS.

Experiences of general home visiting nurses regarding patients with suicidal ideation in Japan: Results from semi-structured interviews

WHAT IS KNOWN ON THE SUBJECT?: The leading reason for suicide attempts in Japan is health problems, among which depression is the most common, followed by physical illnesses. Patients with physical illness and suicide ideation are not rare among patients receiving home-based care. General home visiting nurses (GHVNs) without knowledge, skills or experience in psychiatric care are required to provide care for patients with physical illness who are at risk of suicide in Japan. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: More detailed understanding of GHVNs' experiences and perspectives on working with suicidal patients in home care. This study enriches our understanding of how suicide prevention strategies should be developed for GHVNs. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Focusing education on therapeutic communication skills and meanings with relationships with patients is required by GHVNs. Training for suicide risk assessment and guidelines appropriate to GHVNs' situation is crucial. Establishing a liaison service system with a multidisciplinary team, including psychiatric home-visiting nurses, is necessary for home healthcare to achieve continuity of care. ABSTRACT: Introduction In Japan, even a general home visiting nurse (GHVN) lacking psychiatric experience and training can provide home nursing care to patients at risk of suicide. Little attention is given to nursing care for suicide by GHVNs who care for patients with physical illness. However, these patients with suicidal ideation for home care are surprisingly common. Aim/Question We explored the experiences of GHVNs who cared for patients with suicidal ideation and focused on the nurses' perceptions and interactions. Method We conducted semi-structured interviews with 15 GHVNs. We discussed the nurses' experiences caring for patients with suicidal ideation, their perceptions during these interactions and their response. Results General home visiting nurses were perplexed upon learning of the patient's suicidal ideation. They interacted with such patients by 'avoiding the core of the matter' while focusing on maintaining a relationship with them. Discussion Not addressing the patient's suicidal thoughts will not only disable the suicide risk assessment but also lead to patient isolation. Suicide prevention care needs to consider the unique characteristics of home care. Implications for Practice General home visiting nurses require training in suicide risk assessment and communication skills. Establishing a liaison service, including psychiatric home visiting nurses, is necessary to achieve continuity of care.

A new era for myelin research in Neurofibromatosis type 1

Evidence for myelin regulating higher-order brain function and disease is rapidly accumulating; however, defining cellular/molecular mechanisms remains challenging partially due to the dynamic brain physiology involving deep changes during development, aging, and in response to learning and disease. Furthermore, as the etiology of most neurological conditions remains obscure, most research models focus on mimicking symptoms, which limits understanding of their molecular onset and progression. Studying diseases caused by single gene mutations represents an opportunity to understand brain dys/function, including those regulated by myelin. Here, we discuss known and potential repercussions of abnormal central myelin on the neuropathophysiology of Neurofibromatosis Type 1 (NF1). Most patients with this monogenic disease present with neurological symptoms diverse in kind, severity, and onset/decline, including learning disabilities, autism spectrum disorders, attention deficit and hyperactivity disorder, motor coordination issues, and increased risk for depression and dementia. Coincidentally, most NF1 patients show diverse white matter/myelin abnormalities. Although myelin-behavior links were proposed decades ago, no solid data can prove or refute this idea yet. A recent upsurge in myelin biology understanding and research/therapeutic tools provides opportunities to address this debate. As precision medicine moves forward, an integrative understanding of all cell types disrupted in neurological conditions becomes a priority. Hence, this review aims to serve as a bridge between fundamental cellular/molecular myelin biology and clinical research in NF1.

Occurrence and Severity of Suicidal Ideation in Adults With Neurofibromatosis Participating in a Mind-Body RCT

BACKGROUND

Emotional distress can lead to suicidal ideation and potentially suicide completion, yet there is very little literature on suicidal ideation in individuals with a diagnosis of neurofibromatosis (NF; NF1, NF2, and schwannomatosis).

OBJECTIVE

To examine the baseline occurrence, severity, and clinical correlates of suicidal ideation in adults with NF.

METHOD

Individuals with NF (N = 220) completed assessments measuring depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), perceived stress (Perceived Stress Scale-10), pain (Graded Chronic Pain Scale and PROMIS Pain Interference Short Form 8a), and general quality of life (World Health Organization Quality of Life-Brief version) before beginning a two-arm, single-blind randomized control trial of a live-video mind-body program for stress management and resiliency.

RESULTS

Nineteen percent (n = 42) of the individuals experienced suicidal ideation (ie, >0; ideation present several days or greater). More individuals with NF2 experienced suicidal ideation compared with those with NF1 or schwannomatosis. All of the clinical variables except pain intensity were significantly correlated ( P < 0.01) with greater suicidal ideation. Suicidal ideation in individuals with NF was comparable to or higher than that in other medical populations (eg, cancer, dermatological, neurologic). Depression and poor psychological quality of life significantly increased the risk for suicidal ideation.

CONCLUSION

Suicidal ideation was relatively prevalent in individuals with NF seeking participation in a mind-body randomized controlled trial. NF clinicians should be prepared to discuss these concerns and provide resources when suicidal ideation is present.
