Abstract
Neurodevelopmental proteasomopathies represent a distinctive category of neurodevelopmental disorders (NDD) characterized by genetic variations within the 26S proteasome, a protein complex governing eukaryotic cellular protein homeostasis. In our comprehensive study, we identified 23 unique variants in PSMC5 , which encodes the AAA-ATPase proteasome subunit PSMC5/Rpt6, causing syndromic NDD in 38 unrelated individuals. Overexpression of PSMC5 variants altered human hippocampal neuron morphology, while PSMC5 knockdown led to impaired reversal learning in flies and loss of excitatory synapses in rat hippocampal neurons. PSMC5 loss-of-function resulted in abnormal protein aggregation, profoundly impacting innate immune signaling, mitophagy rates, and lipid metabolism in affected individuals. Importantly, targeting key components of the integrated stress response, such as PKR and GCN2 kinases, ameliorated immune dysregulations in cells from affected individuals. These findings significantly advance our understanding of the molecular mechanisms underlying neurodevelopmental proteasomopathies, provide links to research in neurodegenerative diseases, and open up potential therapeutic avenues.

Abstract
BACKGROUND We investigated the phenotypes and genotypes of a cohort of 'long-surviving' individuals with motor neuron disease (MND) to identify potential targets for prognostication. METHODS Patients were recruited via the Clinical Audit Research and Evaluation for MND (CARE-MND) platform, which hosts the Scottish MND Register. Long survival was defined as > 8 years from diagnosis. 11 phenotypic variables were analysed. Whole genome sequencing (WGS) was performed and variants within 49 MND-associated genes examined. Each individual was screened for C9orf72 repeat expansions. Data from ancestry-matched Scottish populations (the Lothian Birth Cohorts) were used as controls. RESULTS 58 long survivors were identified. Median survival from diagnosis was 15.5 years. Long survivors were significantly younger at onset and diagnosis than incident patients and had a significantly longer diagnostic delay. 42% had the MND subtype of primary lateral sclerosis (PLS). WGS was performed in 46 individuals: 14 (30.4%) had a potentially pathogenic variant. 4 carried the known SOD1 p.(Ile114Thr) variant. Significant variants in FIG4, hnRNPA2B1, SETX, SQSTM1, TAF15, and VAPB were detected. 2 individuals had a variant in the SPAST gene suggesting phenotypic overlap with hereditary spastic paraplegia (HSP). No long survivors had pathogenic C9orf72 repeat expansions. CONCLUSIONS Long survivors are characterised by younger age at onset, increased prevalence of PLS and longer diagnostic delay. Genetic analysis in this cohort has improved our understanding of the phenotypes associated with the SOD1 variant p.(Ile114Thr). Our findings confirm that pathogenic expansion of C9orf72 is likely a poor prognostic marker. Genetic screening using targeted MND and/or HSP panels should be considered in those with long survival, or early-onset slowly progressive disease, to improve diagnostic accuracy and aid prognostication.

Abstract
Oligodendrocytes are implicated in amyotrophic lateral sclerosis pathogenesis and display transactive response DNA-binding protein-43 (TDP-43) pathological inclusions. To investigate the cell autonomous consequences of TDP-43 mutations on human oligodendrocytes, we generated oligodendrocytes from patient-derived induced pluripotent stem cell lines harbouring mutations in the TARDBP gene, namely G298S and M337V. Through a combination of immunocytochemistry, electrophysiological assessment via whole-cell patch clamping, and three-dimensional cultures, no differences in oligodendrocyte differentiation, maturation or myelination were identified. Furthermore, expression analysis for monocarboxylate transporter 1 (a lactate transporter) coupled with a glycolytic stress test showed no deficit in lactate export. However, using confocal microscopy, we report TDP-43 mutation-dependent pathological mis-accumulation of TDP-43. Furthermore, using in vitro patch-clamp recordings, we identified functional Ca2+-permeable α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor dysregulation in oligodendrocytes. Together, these findings establish a platform for further interrogation of the role of oligodendrocytes and cellular autonomy in TDP-43 proteinopathy.

Abstract
Background Ireland frequently reports the highest annual Crude Incidence Rates (CIRs) of cryptosporidiosis in the EU, with national CIRs up to ten times the EU average. Accordingly, the current study sought to examine the spatiotemporal trends associated with this potentially severe protozoan infection. Methods Overall, 4509 cases of infection from January 2008 to December 2017 were geo-referenced to a Census Small Area (SA), with an ensemble of geo-statistical approaches including seasonal decomposition, Local Moran’s I, and space–time scanning used to elucidate spatiotemporal patterns of infection. Results One or more confirmed cases were notified in 3413 of 18,641 Census SAs (18.3%), with highest case numbers occurring in the 0–5-year range (n = 2672, 59.3%). Sporadic cases were more likely male (OR 1.4) and rural (OR 2.4), with outbreak-related cases more likely female (OR 1.4) and urban (OR 1.5). Altogether, 55 space–time clusters (≥ 10 confirmed cases) of sporadic infection were detected, with three “high recurrence” regions identified; no large urban conurbations were present within recurrent clusters. Conclusions Spatiotemporal analysis represents an important indicator of infection patterns, enabling targeted epidemiological intervention and surveillance. Presented results may also be used to further understand the sources, pathways, receptors, and thus mechanisms of cryptosporidiosis in Ireland.

Abstract
OBJECTIVE In this population-based study, we aimed to determine whether neuropsychiatric history, medication or family history of neuropsychiatric disorders predicted cognitive and/or behavioural impairment in motor neuron disease (MND). METHODS People with MND (pwMND) on the Scottish Clinical, Audit, Research and Evaluation of MND (CARE-MND) register, diagnosed from January 2015 to January 2018, with cognitive and/or behavioural data measured using the Edinburgh Cognitive and Behavioural ALS Screen were included. Data were extracted on patient neuropsychiatric, medication and family history of neuropsychiatric disorders. We identified patients with cognitive impairment (motor neuron disease with cognitive impairment (MNDci)), behavioural impairment (motor neuron disease with behavioural impairment (MNDbi), both (motor neuron disease with cognitive and behavioural impairment (MNDcbi)) or motor neuron disease-frontotemporal dementia (MND-FTD). RESULTS Data were available for 305 pwMND (mean age at diagnosis=62.26 years, SD=11.40), of which 60 (19.7%) had a neuropsychiatric disorder. A family history of neuropsychiatric disorders was present in 36/231 (15.58%) of patients. Patient premorbid mood disorders were associated with increased apathy (OR=2.78, 95% CI 1.083 to 7.169). A family history of any neuropsychiatric disorder was associated with poorer visuospatial scores, MNDbi (OR=3.14, 95% CI 1.09 to 8.99) and MND-FTD (OR=5.08, 95% CI 1.26 to 20.40). A family history of mood disorders was associated with poorer overall cognition (exp(b)=0.725, p=0.026), language, verbal fluency and visuospatial scores, and MND-FTD (OR=7.57, 95% CI 1.55 to 46.87). A family history of neurotic disorders was associated with poorer language (exp(b)=0.362, p<0.001), visuospatial scores (exp(b)=0.625, p<0.009) and MND-FTD (OR=13.75, 95% CI 1.71 to 110.86). CONCLUSION Neuropsychiatric disorders in patients and their families are associated with cognitive and behavioural changes post-MND diagnosis, with many occurring independently of MND-FTD and C9orf72 status. These findings support an overlap between MND, frontotemporal dementia and neuropsychiatric disorders, particularly mood disorders.

Abstract
Reports suggest an association between internet use and the elevated risk of suicide and self harm. This study examined the resources a suicidal person might find when searching the internet 'front page' for help. Voluntary suicide help websites accounted for 7/12 front page hits. The National Suicide Research Foundation (NSRF) and the National Office for Suicide Prevention (NOSP), a blog and a newspaper article made up the remainder. Sites were difficult to navigate and highly variable in content. Phone credit was required in many cases in order to contact helplines; opening hours and locations were limited. Most statutory websites referred help-seekers to the voluntary sector, mainly the Samaritans. Information on fundraising and volunteering competed with other sources of help. Of concern, the front page also included links to methods to complete suicide. Irish professional medical bodies offered very limited advice. Our findings suggest that online information is variable and potentially harmful. There is an opportunity for all agencies and providers to generate a co-ordinated internet front page tailored for at-risk groups.
