Cognition, health-related quality of life, and mood in children and young adults diagnosed with a glioneuronal tumor in childhood

The concomitant anxiety and depression in patients with epilepsy caused by low-grade brain tumors

The aim of the study was to evaluate the concomitant psychiatric disorders of anxiety and depression in patients with epilepsy caused by low-grade brain tumors (LBTs). We retrospectively reviewed the clinical data of patients who underwent preoperative neuropsychological evaluations of anxiety and depression and subsequent epilepsy surgery for LBTs. The univariate and multivariate analyses were conducted to analyze the risk factors of the occurrence of anxiety and depression. Of the 107 patients included in the study, 42 patients (39.3%) were female, and 28 patients (26.2%) were children. The median age at surgery was 22 years (interquartile range [IQR]: 17-27 years old), the median age of seizure onset was 12 years (IQR: 6-18 years old), and the median duration of epilepsy was 84 months (IQR: 42-180 months). In total, 21 patients (19.6%) had psychiatric disorders of anxiety, and 26 patients (24.3%) had psychiatric disorders of depression. Through univariate and multivariate analysis, discordant (vs. concordant) interictal electroencephalogram (EEG) findings were found to be related to the presence of anxiety (P = 0.035, odds ratio [OR] = 3.35). Discordant (vs. concordant) ictal EEG findings (P = 0.015, OR = 4.44) and temporal location of tumor (P = 0.015, OR = 13.52) were found to be associated with the presence of depression. Psychiatric disorders of anxiety and/or depression could frequently occur in patients with epilepsy caused by LBTs. Thus, early screening and mental intervention are necessary, especially for those with discordant or wider epileptic discharges and temporal invasion of tumors.

Neuropsychiatric Symptoms After Brain Tumor Resection in Children and Adolescents: A Scoping Review

BACKGROUND

Brain tumors are one of the most common solid tumors in pediatric populations, with their treatments having significant neuropsychiatric impact.

OBJECTIVE

The objective of this study was to review the literature on neuropsychiatric sequelae after surgical resection of brain tumors in children and adolescents.

METHODS

Using a scoping method, we reviewed empirical articles describing pediatric patients with brain tumors who underwent partial or total resection and examined major neuropsychiatric domains postoperatively over time.

RESULTS

The initial search yielded 15,543 articles. After duplicate removal, abstract screening, and review, 44 articles were included. Cognitive deficits were the most widely studied outcomes and found to be associated with tumor location, operative variables, perioperative complications, treatment types, and psychosocial factors. Cerebellar mutism, or posterior fossa syndrome, commonly co-occurred with emotional and behavioral dysregulation after posterior fossa resections. Depression, anxiety, and somatization were frequently grouped together as "distress," with higher rates among pediatric patients with brain tumor than among healthy peers. Problematic school behaviors, antisocial, and attention-deficit traits were increased; however, several other behaviors (e.g., risky sexual behaviors, substance use) were equal or lower when compared to peers. Posttraumatic stress disorder was highly prevalent and often interfered with social functioning. Delirium, eating disorders, and longer-term outcomes received inadequate attention.

CONCLUSION

Identifying risk factors of neuropsychiatric sequelae and their impact after pediatric brain tumor resection is important for prognostication and the development of tailored management strategies for these children and adolescents.

Somatostatin receptor expression and mTOR pathway activation in glioneuronal tumours of childhood

PURPOSE

To investigate the expression of somatostatin receptors (SSTRs) and markers of mTOR pathway in paediatric glioneuronal tumours and correlate these findings with tumour type, BRAFV600E mutational status and clinical characteristics such as tumour location, seizure frequency and duration, and age.

METHOD

37 children and adolescents with a neuropathological diagnosis of glioneuronal tumour were identified over a 22-year period. Immunohistochemical analyses for SSTRs type 1, 2A, 3, 5 and ezrin-radixin-moesin (ERM) and phosphorylated S6 (pS6), which are indicators of mTOR pathway activation, were performed in tumour specimens from 33 patients and evaluated using the immunoreactive score (IRS). The IRS were compared to tumour type, BRAFV600E status and clinical characteristics.

RESULTS

Ganglioglioma (GG) was the most frequently encountered subgroup (n = 27), followed by dysembryoplastic neuroepithelial tumour (DNET; n = 4). GGs expressed SSTR2A and SSTR3 to a high extent, 56 % and 44 % respectively. Expression of SSTR2A was also found in DNETs. Signs of mTOR pathway activation were abundant in GGs, but only present in one DNET. No correlations with BRAFV600E presence or clinical characteristics were found.

CONCLUSIONS

Expression of SSTRs and activation of mTOR pathway in paediatric glioneuronal tumour suggest that somatostatin analogues and mTOR inhibitors may have potential therapeutic implications in a subset of inoperable childhood glioneuronal tumours causing medically refractory epilepsy and/or tumour growth. Further clinical studies are warranted to validate these findings.

Survey of nocturnal reflux in patients with gastroesophageal reflux disease in China

To evaluate current diagnosis and treatment of patients with nocturnal gastroesophageal reflux (nGER).

METHODS

This multicenter observational study was conducted in 44 hospitals in China from May 2017 to February 2018. Outpatients with nGER were recruited and their relevant data were collected using a questionnaire, including age, gender, body mass index, history of smoking and alcohol consumption, comorbid diseases, lifestyle, self-reported health status, medical history, nGER symptoms and severity, Hospital Anxiety Depression Scale, Pittsburgh Sleep Quality Index, diagnosis and treatment choices. The study was registered on the Chinese Clinical Trial Registry (no. ChiCTR1800017525).

RESULTS

The study included 4978 individuals, with valid questionnaires collected from 4448 patients (89.4%). The symptoms of heartburn and regurgitation were more severe at night than during the day (P < 0.05). Age and body mass index were positively correlated with reflux severity at night and during the day (P < 0.05). The severity of nGER was positively associated with lifestyle factors such as smoking, a high-fat diet, carbonated beverage consumption, late supper (later than 9 pm), and snoring (all P < 0.05). Night-time heartburn and regurgitation were related with sleep disorder.

CONCLUSIONS

Lifestyle factors are associated with nGER severity, and nGER affects sleep quality. It will be beneficial to popularize and strengthen the diagnosis and treatment of nGER.
