Abstract Background Pediatric trauma can lead to serious visual impairment as a result of the trauma itself or secondary to amblyopia. Precise data on epidemiological characteristics and visual outcomes of pediatric ocular injuries are valuable for the prevention of monocular blindness. Methods A total of 268 cases of pediatric ocular trauma admitted to the Department of Ophthalmology of the Lithuanian University of Health Sciences Hospital from January 2008 to December 2013 were retrospectively reviewed. Data analysed included age, sex, cause, type and treatment of injury, initial and final visual acuity (VA) and tissues involvement. Eye injuries were classified by Birmingham Eye Trauma Terminology (BETT) and Ocular Trauma Classification System (OTCS). Results The age of children ranged from 6 months to 17.5 years. Boys were more likely to suffer ocular injury than girls. Home was the leading place of eye injury (60.4%), followed by outdoors (31.7%), school (5.2%) and sporting area (2.2%). The highest percentage of eye injuries in children were caused by blunt (40.3%) and sharp objects (29.9%), followed by burns (9.3%), falls (6.7%), explosions (4.5%), fireworks (4.1%), gunshots (1.9%) and traffic accidents (0.7%). Closed globe injury (CGI) was the most common type of eye injury (53.4%). CGI were noted to be higher in children aged 13–18 years, while open globe injury (OGI) were higher in the pre-school age group. Injury of grade 4 and grade 5 were more common in OGI, while grade 1 and grade 2 predominated in cases of CGI. Hypotony, traumatic cataract, iris laceration, vitreous prolapse and uveitis were the most common presentations of OGI, while hyphema, secondary glaucoma and retinal edema were significantly related with CGI. Final diagnoses contributing to poor final visual outcome such as corneal scar corneal opacity, hypotony, aphakia, and retinal detachment were statistically significant related only with OGI. Overall, 65.63% of children regained good visual acuity (VA ≥ 0.5), but for 18.4% of them, the trauma resulted in severe visual impairment (VA ≤ 0.1). Conclusion Ocular trauma in children still remains an important preventable cause of ocular morbidity. This study provides data indicating that ophthalmological injuries are a significant cause of visual impairment in children.

INTRODUCTION: The Mnemonic Similarity Task (MST) is a widely used measure of individual tendency to discern small differences between remembered and presently presented stimuli. Significant work has established this measure as a reliable index of neurological and cognitive dysfunction and decline. However, questions remain about the neural and psychological mechanisms that support performance in the task. METHODS: Here, we provide new insights into these questions by fitting seven previously-collected MST datasets (total N = 519), adapting a three-choice evidence accumulation model (the Linear Ballistic Accumulator). The model decomposes choices into automatic and deliberative components. RESULTS: We show that these decomposed processes both contribute to the standard measure of behavior in this task, as well as capturing individual variation in this measure across the lifespan. We also exploit a delayed test/re-test manipulation in one of the experiments to show that model parameters exhibit improved stability, relative to the standard metric, across a 1 week delay. Finally, we apply the model to a resting-state fMRI dataset, finding that only the deliberative component corresponds to off-task co-activation in networks associated with long-term, episodic memory. DISCUSSION: Taken together, these findings establish a novel mechanistic decomposition of MST behavior and help to constrain theories about the cognitive processes that support performance in the task.

Abstract Background Sex differences exist in the prevalence and progression of major glomerular diseases. Podocytes are the essential cell-type in the kidney which maintain the physiological blood-urine barrier, and pathological changes in podocyte homeostasis are critical accelerators of impairment of kidney function. However, sex-specific molecular signatures of podocytes under physiological and stress conditions remain unknown. This work aimed at identifying sexual dimorphic molecular signatures of podocytes under physiological condition and pharmacologically challenged homeostasis with mechanistic target of rapamycin (mTOR) inhibition. mTOR is a crucial regulator involved in a variety of physiological and pathological stress responses in the kidney and inhibition of this pathway may therefore serve as a general stress challenger to get fundamental insights into sex differences in podocytes. Methods The genomic ROSAmT/mG-NPHS2 Cre mouse model was used which allows obtaining highly pure podocyte fractions for cell-specific molecular analyses, and vehicle or pharmacologic treatment with the mTOR inhibitor rapamycin was performed for 3 weeks. Subsequently, deep RNA sequencing and proteomics were performed of the isolated podocytes to identify intrinsic sex differences. Studies were supplemented with metabolomics from kidney cortex tissues. Results Although kidney function and morphology remained normal in all experimental groups, RNA sequencing, proteomics and metabolomics revealed strong intrinsic sex differences in the expression levels of mitochondrial, translation and structural transcripts, protein abundances and regulation of metabolic pathways. Interestingly, rapamycin abolished prominent sex-specific clustering of podocyte gene expression and induced major changes only in male transcriptome. Several sex-biased transcription factors could be identified as possible upstream regulators of these sexually dimorphic responses. Concordant to transcriptomics, metabolomic changes were more prominent in males. Remarkably, high number of previously reported kidney disease genes showed intrinsic sexual dimorphism and/or different response patterns towards mTOR inhibition. Conclusions Our results highlight remarkable intrinsic sex-differences and sex-specific response patterns towards pharmacological challenged podocyte homeostasis which might fundamentally contribute to sex differences in kidney disease susceptibilities and progression. This work provides rationale and an in-depth database for novel targets to be tested in specific kidney disease models to advance with sex-specific treatment strategies.

BACKGROUND: Neurological opportunistic infections cause significant morbidity and mortality in people with human immunodeficiency virus (HIV) but are difficult to diagnose. METHODS: One hundred forty people with HIV with acute neurological symptoms from Iquitos, Peru, were evaluated for cerebral toxoplasmosis with quantitative polymerase chain reaction (qPCR) of cerebrospinal fluid (CSF) and for cryptococcal meningitis with cryptococcal antigen test (CrAg) in serum or CSF. Differences between groups were assessed with standard statistical methods. A subset of samples was evaluated by metagenomic next-generation sequencing (mNGS) of CSF to compare standard diagnostics and identify additional diagnoses. RESULTS: Twenty-seven participants were diagnosed with cerebral toxoplasmosis by qPCR and 13 with cryptococcal meningitis by CrAg. Compared to participants without cerebral toxoplasmosis, abnormal Glasgow Coma Scale score (P = .05), unilateral focal motor signs (P = .01), positive Babinski reflex (P = .01), and multiple lesions on head computed tomography (CT) (P = .002) were associated with cerebral toxoplasmosis. Photophobia (P = .03) and absence of lesions on head CT (P = .02) were associated with cryptococcal meningitis. mNGS of 42 samples identified 8 cases of cerebral toxoplasmosis, 7 cases of cryptococcal meningitis, 5 possible cases of tuberculous meningitis, and incidental detections of hepatitis B virus (n = 1) and pegivirus (n = 1). mNGS had a positive percentage agreement of 71% and a negative percentage agreement of 91% with qPCR for T gondii. mNGS had a sensitivity of 78% and specificity of 100% for Cryptococcus diagnosis. CONCLUSIONS: An infection was diagnosed by any method in only 34% of participants, demonstrating the challenges of diagnosing neurological opportunistic infections in this population and highlighting the need for broader, more sensitive diagnostic tests for central nervous system infections.

Abstract The clinical course of COVID-19 is variable and often unpredictable. To test the hypothesis that disease progression and inflammatory responses associate with alterations in the microbiome and metabolome, we analyzed metagenome, metabolome, cytokine, and transcriptome profiles of repeated samples from hospitalized COVID-19 patients and uninfected controls, and leveraged clinical information and post-hoc confounder analysis. Severe COVID-19 was associated with a depletion of beneficial intestinal microbes, whereas oropharyngeal microbiota disturbance was mainly linked to antibiotic use. COVID-19 severity was also associated with enhanced plasma concentrations of kynurenine and reduced levels of several other tryptophan metabolites, lysophosphatidylcholines, and secondary bile acids. Moreover, reduced concentrations of various tryptophan metabolites were associated with depletion of Faecalibacterium, and tryptophan decrease and kynurenine increase were linked to enhanced production of inflammatory cytokines. Collectively, our study identifies correlated microbiome and metabolome alterations as a potential contributor to inflammatory dysregulation in severe COVID-19.

Objective This study aimed to investigate the efficacy of Bacillus-based probiotics supplemented at two different levels to modulate the productive performance, egg quality, tibia traits, and specific cecal bacteria counts of Hy-Line Brown layers from 25 to 37 weeks of age. Methods A total of 216 twenty-five-week-old hens were randomly distributed into 3 experimental diets with 12 replicates of 6 birds per cage. Diets included basal diet supplemented with 0 (CON), 3×108 (PRO1), or 3×109 (PRO2) colony-forming unit (CFU) of the test probiotic containing Bacillus subtilis PB6, Bacillus subtilis FXA, and Bacillus licheniformis G3 per kilogram of feed. Results Improved egg weights and mass at 29 weeks; and feed intake at 31 weeks (p

Trauma-informed care (TIC) benefits to service users and providers are increasingly acknowledged across various health and social care settings. TIC can potentially increase service user engagement, prolong shelter placements, and lessen staff vicarious trauma and burnout. However, studies documenting staff experiences and/or the implementation of TIC are scarce. This limitation has prompted calls for more grounded and applied research into trauma-informed practice, tracking implementation in practice, staff perceptions, barriers, and organisational change. This study aims to address this gap and is an ecological, mixed-methods evaluation of the efficacy of TIC training in a female-only homeless shelter. Quantitative data included 132 incident reports during the first yearly quarters pre- and post-training, hypothesising post-training reductions in incident numbers and severity. Using expansive thematic analysis, semi-structured interviews with six shelter staff (n = 6) explored employee views of TIC relative to trauma understanding, incident management, and integration in practice. Findings revealed a marginal increase in incident numbers and a statistically significant reduction in incident severity post-TIC with a 50% reduction in calls to emergency medical services (EMS). Participant accounts of working practice pre- and post-TIC uncovered increased trauma understanding, increased confidence and competence, healing relationships, and enhanced self-care. Findings are discussed with reference to Substance Abuse and Mental Health Services Administration (SAMHSA)’s (2014) trauma-informed framework and Yatchmenoff et al’s. (2017) core questions in evaluating TIC. While these results are significant as one of the first evaluations of TIC training in Ireland, limitations and implications for future research and practice are considered.
