AI Article Synopsis
- Limited data exists on Parkinson's disease (PD) in South Africa, with a study analyzing hospital records from 2002-2016 identifying 414 PD patients across various ethnic groups.
- The median age of onset was 60 years, with a male predominance and no significant differences in clinical profiles among ethnicities, although Indian and White patients exhibited more severe symptoms.
- The findings indicate an increasing prevalence of PD, emphasizing the importance of allocating healthcare resources for neurodegenerative disorders in an aging African population.
Article Abstract
Background: There is limited data on Parkinson's disease (PD) in South Africa.
Methods: Demographic and clinical information was extracted from the hospital records of patients who were coded as PD (International Classification of Diseases, 10th revision, G20) from 2002 to 2016.PD was diagnosed using the United Kingdom Parkinson's Disease Society Brain Bank Clinical Diagnostic Criteria (UKBBC).
Results: 414 patients met the criteria, 194 Indian, 130 Black, 16 Mixed Ancestry and 74 White patients. Median age at onset was 60 years, 53% were male and 20% had early onset PD (EOPD). There were no differences between the ethnic groups for the male: female ratio, age at onset, frequency of EOPD, family history, clinical phenotype and disease severity. Dyskinesia and neuropsychiatric symptoms were more frequent in Indian and White patients (p < 0.001). PD referral centre prevalence was 23/1000 neurological cases for the period 2002-2016. Referral centre prevalence of PD was 2.8 times higher in White compared to Black patients. Our study demonstrates an increase in referral centre prevalence of PD since the last clinical series in 1988 and an age related increase in prevalence.
Conclusions: PD prevalence is increasing. The clinical profile of PD in Black patients is similar to the other ethnic groups. This study highlights the need for health care resource allocation to neurodegenerative disorders in an ageing African continent.

The widespread application of genome editing to treat and cure disease requires the delivery of genome editors into the nucleus of target cells. Enveloped delivery vehicles (EDVs) are engineered virally derived particles capable of packaging and delivering CRISPR-Cas9 ribonucleoproteins (RNPs). However, the presence of lentiviral genome encapsulation and replication proteins in EDVs has obscured the underlying delivery mechanism and precluded particle optimization.

Significance: In an aging population, the number of people living with neurodegenerative disease is projected to increase. It is vital to develop reliable, noninvasive biomarkers to detect disease onset and monitor progression, and there is a growing body of research into the ocular surface as a potential source of such biomarkers.

This study utilises amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD) human brain samples from the GEO database and employs differential expression gene (DEG) analysis to identify genes that are pivotal in both neurodegenerative diseases. Through in depth GO and KEGG enrichment analyses, we elucidated the biological functions and potential pathways associated with these DEGs. Furthermore, by constructing protein‒protein interaction networks, we highlight the significance of shared DEGs in both cellular physiology and disease contexts.

Neurological disorders (NDs), such as amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and schizophrenia, represent a complex and multifaceted health challenge that affects millions of people around the world. Growing evidence suggests that disrupted neuronal calcium signalling contributes to the pathophysiology of NDs. Additionally, calcium functions as a ubiquitous second messenger involved in diverse cellular processes, from synaptic activity to intercellular communication, making it a potential therapeutic target.
