Traditional/alternative and complementary medicine (TCM) encompasses products, practices and practitioners that do not form part of conventional treatment and are not an integral part of the main health care systems. They are very common in the management of epilepsy and mental health conditions, particularly in low- and middle-income countries (LMIC). For instance, in a population-based survey in Africa, over 70% of people with epilepsy had visited a traditional health practitioner before the survey, with similarly high estimates reported in Asia and South America.

Article Synopsis
  • The Global Burden of Disease Study (GBD) provides estimates for prevalence of idiopathic and secondary epilepsy but lacks detailed prevalence by the specific underlying causes of secondary epilepsy.
  • Using demographic data from Denmark, researchers identified causes of epilepsy to compare local prevalence rates with GBD 2019 data, analyzing hospital diagnoses and prescription records from 2009 to 2018.
  • Results showed that Denmark has a total epilepsy prevalence of 697 per 100,000, with significant underlying causes for secondary epilepsy including perinatal conditions, traumatic brain injury, brain tumors, and stroke, suggesting a need for future studies to address all forms of epilepsy more comprehensively.

Article Synopsis
  • - The PUMAS project aims to address the lack of representation of African and Latin American populations in psychiatric genetics studies by analyzing genetic data from individuals with serious mental illness (SMI), including disorders like schizophrenia and bipolar disorder, using data from 89,320 participants across four different cohorts.
  • - The research involves harmonizing data from various clinical assessments to create standardized measures of mental health symptoms, which allows for more accurate genetic analyses across different diagnoses and symptoms.
  • - The findings show that schizophrenia and severe bipolar disorder are the most common diagnoses among participants, and a set of 19 key symptoms has been identified, which may be useful for cross-diagnosis genetic studies.

The availability of quality and timely data for routine monitoring of mental, neurological and substance use (MNS) disorders is a challenge, particularly in Africa. We assessed the feasibility of using an open-source data science technology (R Shiny) to improve health data reporting in Nairobi City County, Kenya. Based on a previously used manual tool, in June 2022, we developed a digital online data capture and reporting tool using the open-source Kobo toolbox.

Background: Most children with developmental disabilities (DD) live in low- and middle-income countries, but access to services is limited, impacting their ability to thrive. Pilot study findings of the World Health Organization's Caregiver Skills Training (WHO CST) intervention, which equips caregivers with strategies to facilitate learning and adaptive behaviours in children with DD, are promising but evidence from an appropriately powered trial delivered by non-specialist facilitators is lacking. This study will investigate the effectiveness and the resource impacts and costs and consequences of the WHO CST intervention in four sites in rural and urban Kenya and Ethiopia.

Article Synopsis
  • Epilepsy is a major public health issue in Tanzania, particularly in Mahenge, where stigma and misconceptions significantly impact the lives of affected individuals.
  • A study involving 778 participants revealed that while most were aware of epilepsy, their knowledge was low, leading to negative attitudes and misconceptions about the disorder's causes, such as witchcraft and hereditary factors.
  • Stigma towards individuals with epilepsy was prevalent, resulting in social isolation and barriers to education, with traditional healers often being the first point of treatment despite the lack of understanding of the condition.

We deployed the Blended Genome Exome (BGE), a DNA library blending approach that generates low pass whole genome (1-4× mean depth) and deep whole exome (30-40× mean depth) data in a single sequencing run. This technology is cost-effective, empowers most genomic discoveries possible with deep whole genome sequencing, and provides an unbiased method to capture the diversity of common SNP variation across the globe. To evaluate this new technology at scale, we applied BGE to sequence >53,000 samples from the Populations Underrepresented in Mental Illness Associations Studies (PUMAS) Project, which included participants across African, African American, and Latin American populations.

Background: African children with cerebral malaria and seizures caused are at greater risk of poor outcomes including death and neurological sequelae. The agonal events are severe hypoventilation and respiratory arrest often triggered by seizures. We hypothesised that prophylactic anti-seizure medication (ASM) could avert 'spikes' of intracranial pressure during or following seizures and that adequate ventilation could be supported by biphasic Cuirass Ventilation (BCV) which requires no intubation.

The impact of cerebral malaria on the transcriptional profiles of cerebral tissues is difficult to study using noninvasive approaches. We isolated plasma extracellular vesicles (EVs) from patients with cerebral malaria and community controls and sequenced their mRNA content. Deconvolution analysis revealed that EVs from cerebral malaria are enriched in transcripts of brain origin.
