Magnitude and concurrence of anxiety and depression among attendees with multiple sclerosis at a tertiary care Hospital in Oman.

BACKGROUND: Anxiety, depression and functional impairments are commonly reported by persons with multiple sclerosis (PwMS) but no data, to our knowledge, has emerged from an Arab Islamic population. The study aims to investigate the prevalence of anxiety, depression and related disabilities among PwMS attending tertiary care in Sultan Qaboos University Hospital (SQUH), one of the urban hospitals in Oman. METHODS: Consecutive and consenting PwMS (n = 57) and healthy subjects (n = 53) completed the following measures: Hospital Anxiety and Depression Scale (HADS) which was used to measure anxiety (cut-point >7) and depression (>7); and Expanded Disability Status Scale (EDSS) to measure the level of disability (≥5). Characteristics such as socio-demographic and clinical variables were also explored. RESULTS: Fifty seven subjects with multiple sclerosis (MS) met the inclusion criteria. The majority of them were females who were 40 years old or younger and the majority were employed and unmarried. Approximately 86 % of the participants were using beta interferon, 96 % scored ≥5 in EDSS. MS of the Relapsing-Remitting type constituted the majority of the cohort (94 %). Approximately 35 % and 51 % endorsed symptoms of anxiety and depression respectively. The MS group scored significantly higher than controls on HADS measurements of depression and anxiety. CONCLUSION: Disability and symptoms of anxiety and depression are common among the PwMS attendees of tertiary care hospital in Oman. Such psychosocial variables have been largely unreported emerging from non-western populations. As these variables are strong indicators of the burden of MS, resolute effort is needed to address such psychosocial dysfunctions in the algorithms of care for PwMS in the Arab Islamic part of the world.

Impact of a Pediatric Cardiology Clinical Program on Congenital Heart Disease Outcomes in Guyana.

Background: Children with congenital heart disease (CHD) in Guyana have not historically been managed with timely intervention, increasing the likelihood of serious, irreversible complications. In 2014, a pediatric cardiology clinical program (Guyana Paediatric Cardiology Steering Committee [GPCSC]) and partnership with International Children's Heart Foundation (BabyHeart) was developed to improve CHD care. Objectives: To describe the characteristics of CHD in Guyanese children and to determine the impact of GPCSC on CHD outcomes. Methods: Qualitative comparison between CHD patients sent for surgery prior to GPCSC (pre-GPCSC cohort) and those managed through GPCSC (post-GPCSC cohort). Findings: Eighty-eight pre-GPHC patients were identified from 2005 to 2014. A total of 319 CHD patients were referred post-GPCSC. In all, 114 patients required surgical or catheterization procedures, with 74 patients prioritized for interventions within 29 months post-GPCSC. Mean age at surgery was 77 months in both cohorts, with younger children represented in the post-GPCSC cohort. Postoperative follow-up was more frequent post-GPCSC (100% vs 35%). Vital status of 48% of pre-GPCSC patients is unknown, with more pre-GPCSC patients known to be deceased compared with post-GPCSC (9% vs 5%). Pre-GPCSC patients had more incorrect diagnosis and inoperable disease when sent for surgery. Interpretation: Patients undergoing surgery post-GPCSC had more appropriate and timely interventions, better follow-up, and increased survival. The feasibility and positive impact of this collaborative pediatric cardiology clinical program in Guyana is demonstrated, with potential applicability for other low- and middle-income countries. Obstacles to referral of children with CHD in Guyana can begin to be addressed, with the goal of more complete access to timely intervention, and improved outcomes for these children.

Parental enrichment and offspring development: modifications to brain, behavior and the epigenome.

Environmental enrichment has been shown to have profound effects on the healthy adult brain and as a remedial tool for brains compromised by injury, disease, or negative experience. Based upon these findings and evidence from the prenatal stress literature, we ventured an exploratory study to examine the effects of parental enrichment on offspring development. Using Long Evans rats, paternal enrichment was achieved by housing sires in enriched environments for 28 days prior to mating with a control female. For the maternal enrichment paradigm, female rats were also housed in enriched environments for 28 days (7 days prior to conception and for the duration of pregnancy). Increased size, multiple levels for exploration, an abundance of stimulating toys, and numerous cagemates for social interaction were characteristic of the enriched environments. Offspring were assessed using two early behavioral tests and then sacrificed at postnatal day 21 (P21). Brain tissue from the frontal cortex and hippocampus was harvested for global DNA methylation analysis. Parental enrichment, preconceptionally and prenatally, altered offspring behavior on the negative geotaxis task and openfield exploratory behavior task. Paternal enrichment significantly decreased offspring brain weight at P21. Additionally, both environmental enrichment paradigms significantly decreased global methylation levels in the hippocampus and frontal cortex of male and female offspring. This study demonstrates that positive prenatal experiences; preconceptionally in fathers and prenatally in mothers, have the ability to significantly alter offspring developmental trajectories.
