Virtual Mindfulness-Based Therapy for the Management of Endometriosis Chronic Pelvic Pain: A Novel Delivery Platform to Increase Access to Care.

OBJECTIVES: This study assessed the effectiveness of a virtual mindfulness-based stress reduction (MBSR) program to improve quality of life and pain in people with endometriosis. METHODS: This was a multiple-method, before and after study design. Fifteen patients with a clinical or surgical diagnosis of endometriosis were recruited from a Canadian outpatient gynaecology clinic. Participants completed the Endometriosis Health Profile, a validated survey tool, and a pain medication use questionnaire before and after a virtual 8-week MBSR program run by an experienced social worker. A focus group was held upon completion of the program to assess participants' experiences using mindfulness for management of endometriosis symptoms. Quantitative data was analyzed with paired-samples t tests. Qualitative data was thematically analyzed. RESULTS: A total of 67% of people enrolled completed the MBSR course (10/15). Following the MBSR program, participants had a statistically significant decrease in 4 components of the Endometriosis Health Profile: control and powerlessness (P = 0.012), emotional well-being (P = 0.048), social support (P = 0.030), and self-image (P = 0.014). There was no change in pain scores or medication use. Participants felt the program's benefits came from a sense of community, education about their condition, and application of mindfulness tools when approaching pain. Participants felt more comfortable with the virtual format over in-person sessions. CONCLUSIONS: A virtual MBSR course can improve quality of life domains in people with endometriosis. The virtual format was effective and preferred by participants. Virtual MBSR programs may increase access to this type of care.

Electroencephalographic studies in growth-restricted and small-for-gestational-age neonates.

Foetal growth restriction (FGR) and being born small for gestational age (SGA) are associated with neurodevelopmental delay. Early diagnosis of neurological damage is difficult in FGR and SGA neonates. Electroencephalography (EEG) has the potential as a tool for the assessment of brain development in FGR/SGA neonates. In this review, we analyse the evidence base on the use of EEG for the assessment of neonates with FGR or SGA. We found consistent findings that FGR/SGA is associated with measurable changes in the EEG that present immediately after birth and persist into childhood. Early manifestations of FGR/SGA in the EEG include changes in spectral power, symmetry/synchrony, sleep-wake cycling, and the continuity of EEG amplitude. Later manifestations of FGR/SGA into infancy and early childhood include changes in spectral power, sleep architecture, and EEG amplitude. FGR/SGA infants had poorer neurodevelopmental outcomes than appropriate for gestational age controls. The EEG has the potential to identify FGR/SGA infants and assess the functional correlates of neurological damage. IMPACT: FGR/SGA neonates have significantly different EEG activity compared to AGA neonates. EEG differences persist into childhood and are associated with adverse neurodevelopmental outcomes. EEG has the potential for early identification of brain impairment in FGR/SGA neonates.

Alternative lengthening of telomeres is enriched in, and impacts survival of TP53 mutant pediatric malignant brain tumors.

Although telomeres are maintained in most cancers by telomerase activation, a subset of tumors utilize alternative lengthening of telomeres (ALT) to sustain self-renewal capacity. In order to study the prevalence and significance of ALT in childhood brain tumors we screened 517 pediatric brain tumors using the novel C-circle assay. We examined the association of ALT with alterations in genes found to segregate with specific histological phenotypes and with clinical outcome. ALT was detected almost exclusively in malignant tumors (p = 0.001). ALT was highly enriched in primitive neuroectodermal tumors (12 %), choroid plexus carcinomas (23 %) and high-grade gliomas (22 %). Furthermore, in contrast to adult gliomas, pediatric low grade gliomas which progressed to high-grade tumors did not exhibit the ALT phenotype. Somatic but not germline TP53 mutations were highly associated with ALT (p = 1.01 × 10(-8)). Of the other alterations examined, only ATRX point mutations and reduced expression were associated with the ALT phenotype (p = 0.0005). Interestingly, ALT attenuated the poor outcome conferred by TP53 mutations in specific pediatric brain tumors. Due to very poor prognosis, one year overall survival was quantified in malignant gliomas, while in children with choroid plexus carcinoma, five year overall survival was investigated. For children with TP53 mutant malignant gliomas, one year overall survival was 63 ± 12 and 23 ± 10 % for ALT positive and negative tumors, respectively (p = 0.03), while for children with TP53 mutant choroid plexus carcinomas, 5 years overall survival was 67 ± 19 and 27 ± 13 % for ALT positive and negative tumors, respectively (p = 0.07). These observations suggest that the presence of ALT is limited to a specific group of childhood brain cancers which harbor somatic TP53 mutations and may influence the outcome of these patients. Analysis of ALT may contribute to risk stratification and targeted therapies to improve outcome for these children.
