Abstract
Over the past decade, artificial intelligence (AI) has begun to transform Canadian organizations, driven by the promise of improved efficiency, better decision-making, and enhanced client experience. While AI holds great opportunities, there are also near-term impacts on the determinants of health and population health equity that are already emerging. If adoption is unregulated, there is a substantial risk that health inequities could be exacerbated through intended or unintended biases embedded in AI systems. New economic opportunities could be disproportionately leveraged by already privileged workers and owners of AI systems, reinforcing prevailing power dynamics. AI could also detrimentally affect population well-being by replacing human interactions rather than fostering social connectedness. Furthermore, AI-powered health misinformation could undermine effective public health communication. To respond to these challenges, public health must assess and report on the health equity impacts of AI, inform implementation to reduce health inequities, and facilitate intersectoral partnerships to foster development of policies and regulatory frameworks to mitigate risks. This commentary highlights AI's near-term risks for population health to inform a public health response.

Abstract
Objectives This study investigates the effectiveness of a virtual format of an advanced communication skills observed structured clinical examination (OSCE) for senior medical students in comparison to an in-person format. The study also examines the emotional support students experience in the virtual setting. Our analysis was based on quantitative data collected through objective checklists and post-OSCE survey results. Methods The virtual OSCE was a revision of an earlier in-person formative advanced communication skills OSCE for fourth-year medical students. Student performances were assessed by self and peers using objective checklists-the modified Master Interview Rating Scale (mMIRS) and Communication Behavior Checklist (CBC). The mMIRS measured interview process such as avoiding jargon and demonstrating empathy. The CBC examined interview content which included tasks specific to the content of the case. The OSCE was followed by a faculty-led debrief and quantitative survey. The virtual OSCE was conducted in 2021, and the results of the checklists and survey were compared with those collected from two earlier in-person OSCEs. Results Eighty-three students participated in the virtual OSCE. There was no difference in mMIRS scores between the virtual and in-person OSCE. Overall CBC scores were lower in the virtual OSCE compared to in-person (p < 0.05). Sixty-seven out of 83 (80.7%) students completed the post-OSCE survey. There were no differences between the virtual and in-person OSCE in terms of educational value, whether the OSCE would change the way participants talk to patients, and preparedness to have serious conversations with patients. All respondents somewhat or strongly agreed with feeling emotionally supported during the virtual OSCE. Conclusion The virtual format was a suitable alternative to an in-person, formative, advanced communication skills OSCE for medical students. The virtual OSCE was educationally effective and was met with student satisfaction and a sense of emotional support. Future virtual iterations must ensure adequate instruction on interview content.

Abstract
The development of long-term symptoms of coronavirus disease 2019 (COVID-19) more than four weeks after primary infection, termed "long COVID" or post-acute sequela of COVID-19 (PASC), can implicate persistent neurological complications in up to one third of patients and present as fatigue, "brain fog", headaches, cognitive impairment, dysautonomia, neuropsychiatric symptoms, anosmia, hypogeusia, and peripheral neuropathy. Pathogenic mechanisms of these symptoms of long COVID remain largely unclear; however, several hypotheses implicate both nervous system and systemic pathogenic mechanisms such as SARS-CoV2 viral persistence and neuroinvasion, abnormal immunological response, autoimmunity, coagulopathies, and endotheliopathy. Outside of the CNS, SARS-CoV-2 can invade the support and stem cells of the olfactory epithelium leading to persistent alterations to olfactory function. SARS-CoV-2 infection may induce abnormalities in innate and adaptive immunity including monocyte expansion, T-cell exhaustion, and prolonged cytokine release, which may cause neuroinflammatory responses and microglia activation, white matter abnormalities, and microvascular changes. Additionally, microvascular clot formation can occlude capillaries and endotheliopathy, due to SARS-CoV-2 protease activity and complement activation, can contribute to hypoxic neuronal injury and blood-brain barrier dysfunction, respectively. Current therapeutics target pathological mechanisms by employing antivirals, decreasing inflammation, and promoting olfactory epithelium regeneration. Thus, from laboratory evidence and clinical trials in the literature, we sought to synthesize the pathophysiological pathways underlying neurological symptoms of long COVID and potential therapeutics.

Abstract
Central anticholinergic syndrome (CAS) presents with central and/or peripheral neurological symptoms after exposure to anticholinergic medication. Pain management is a challenge for patients who have CAS and concurrent cancer-related pain. We present a patient who became lethargic and unresponsive after receiving butorphanol, with persistent symptoms despite administration of an opioid antagonist. This case report is the first to suggest a causal relationship between opioids and CAS without the presence of confounding anticholinergic medications. CAS should be considered for patients who develop neurological symptoms after opioid exposure and have an incomplete response to an opioid antagonist.

Abstract
Abstract
Although precision medicine has revolutionized the treatment for other solid tumors, comprehensive genome profiling of hepatocellular carcinoma (HCC) has demonstrated that there are few oncogenic mutational drivers. HCC arises nearly universally in the context of co-morbid hepatitis, driven by hepatitis C virus or hepatitis B virus (HBV). Previous work has highlighted the effects of HBV protein X (HBx) on signaling and proliferation. However, it remains unclear how these signaling changes interact with the stress imposed by HBV replication. We hypothesize that HBV replication and maintenance of HBV proteins like HBx creates specific vulnerabilities that can be uncovered and exploited. We performed whole-genome clustered regularly interspaced short palindromic repeat interference (CRISPRi) screening in two engineered, patient-derived HBV+ cell models, Hep3B and SNU-368, with cellular proliferation as the readout. A conditional induction of HBx was used to overexpress HBx in each cell model for the whole genome CRISPRi screen. Genes where HBx expression was significantly associated with a more negative dependency score were classified as HBV differential dependencies. 37 genes were identified as shared HBV-induced dependencies across both cell lines. Of these, 16 were also differentially expressed in HCC specimens with ongoing HBV replication vs. non-HBV expressing tumors collected in The Cancer Genome Atlas (TCGA), suggesting in vivo selective pressure to alter the expression of these genes. We focused on Zinc Fingers and Homeoboxes 2 (ZHX2) and methionine adenosyltransferase 2A (MAT2A). ZHX2 was identified as an HCC tumor suppressor, and data from TCGA showed differential gene expression of ZHX2 in HBV+HCC. Validation of ZHX2 sgRNA knockdown confirmed that ZHX2 knockdown preferentially reduced cell proliferation in the presence of HBx, consistent with an HBV-induced dependency. ZHX2 also can activate the HIF pathway; we identified alterations of HIF targets with ZHX2 knockdown and HBx expression. Similarly, MAT2A knockdown in HBV+HCC cell lines showed decreased cell proliferation with HBx expression. MAT2A is an emerging therapeutic target, with sensitivity to MAT2A inhibitors conferred by deletions in methylthioadenosine phosphorylase (MTAP), seen in 3% of HCC. Ongoing investigations include alteration of splicing and cell cycle changes with depletion of MAT2A in the presence of HBx. With small molecule inhibitors of MAT2A in clinical development, this finding may be therapeutically actionable. Thus, using functional genomics to interrogate HBV-associated gene dependencies has illuminated the biology of HCC and identified candidate therapeutic targets for pre-clinical validation.

Abstract
Establishing goals of care (GOC) is a crucial component of a patient's treatment plan. The need for better physician-patient communication in this area has been recognized for decades, yet several gaps remain. Challenges exist for both physician and patient. Physicians should pursue a patient-led approach, exercise cultural competency, and use various communication techniques to guide patients when establishing GOC.

Abstract
We present the first joint analysis of cluster abundances and auto or cross-correlations of three cosmic tracer fields: galaxy density, weak gravitational lensing shear, and cluster density split by optical richness. From a joint analysis (4×2pt+N) of cluster abundances, three cluster cross-correlations, and the auto correlations of the galaxy density measured from the first year data of the Dark Energy Survey, we obtain Ω_{m}=0.305_{-0.038}^{+0.055} and σ_{8}=0.783_{-0.054}^{+0.064}. This result is consistent with constraints from the DES-Y1 galaxy clustering and weak lensing two-point correlation functions for the flat νΛCDM model. Consequently, we combine cluster abundances and all two-point correlations from across all three cosmic tracer fields (6×2pt+N) and find improved constraints on cosmological parameters as well as on the cluster observable-mass scaling relation. This analysis is an important advance in both optical cluster cosmology and multiprobe analyses of upcoming wide imaging surveys.

However, the impact of these experiments may be limited by manual, non-standardized, static or qualitative phenotypic analysis. OrgDyn is an open-source and modular pipeline to quantify organoid shape dynamics using a combination of feature- and model-based approaches on time series of 2D organoid contour images. Our pipeline consists of (i) geometrical and signal processing feature extraction, (ii) dimensionality reduction to differentiate dynamical paths, (iii) time series clustering to identify coherent groups of organoids and (iv) dynamical modeling using point distribution models to explain temporal shape variation. OrgDyn can characterize, cluster and model differences among unique dynamical paths that define diverse final shapes, thus enabling quantitative analysis of the molecular basis of tissue development and disease.

Abstract
In recent years, many γ-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-correlation with gravitational tracers of matter in the Universe has been shown to be a promising tool. We report here the first identification of a cross-correlation signal between γ rays and the distribution of mass in the Universe probed by weak gravitational lensing. We use data from the Dark Energy Survey Y1 weak lensing data and the Fermi Large Area Telescope 9-yr γ-ray data, obtaining a signal-to-noise ratio of 5.3. The signal is mostly localized at small angular scales and high γ-ray energies, with a hint of correlation at extended separation. Blazar emission is likely the origin of the small-scale effect. We investigate implications of the large-scale component in terms of astrophysical sources and particle dark matter emission.

Abstract
Dissemination is an essential early step in metastasis but its molecular basis remains incompletely understood. To define the essential targetable effectors of this process, we developed a 3D mammary epithelial culture model, in which dissemination is induced by overexpression of the transcription factor Twist1. Transcriptomic analysis and ChIP-PCR together demonstrated that protein kinase D1 (Prkd1) is a direct transcriptional target of Twist1 and is not expressed in the normal mammary epithelium. Pharmacologic and genetic inhibition of Prkd1 in the Twist1-induced dissemination model demonstrated that Prkd1 was required for cells to initiate extracellular matrix (ECM)-directed protrusions, release from the epithelium, and migrate through the ECM. Antibody-based protein profiling revealed that Prkd1 induced broad phosphorylation changes, including an inactivating phosphorylation of β-catenin and two microtubule depolymerizing phosphorylations of Tau, potentially explaining the release of cell-cell contacts and persistent activation of Prkd1. In patients with breast cancer, TWIST1 and PRKD1 expression correlated with metastatic recurrence, particularly in basal breast cancer. Prkd1 knockdown was sufficient to block dissemination of both murine and human mammary tumor organoids. Finally, Prkd1 knockdown in vivo blocked primary tumor invasion and distant metastasis in a mouse model of basal breast cancer. Collectively, these data identify Prkd1 as a novel and targetable signaling node downstream of Twist1 that is required for epithelial invasion and dissemination. SIGNIFICANCE: Twist1 is a known regulator of metastatic cell behaviors but not directly targetable. This study provides a molecular explanation for how Twist1-induced dissemination works and demonstrates that it can be targeted.

Abstract
BACKGROUND Electronic nicotine delivery systems (ENDSs), including electronic cigarettes (e-cigarettes), are rapidly gaining popularity. The aim of this study was to use poison centre data to describe epidemiological trends in ENDS-related exposures. METHODS We conducted an observational case series study using records containing both coded fields and free-text narratives from the British Columbia Drug and Poison Information Centre for all calls involving exposure to ENDS received from 2012 to 2017. We described trends in exposures and exposed people, as well as clinical effects. RESULTS A total of 243 calls were recorded for 186 unique exposures to ENDS devices, e-juice, e-cigarette cartridges and other associated paraphernalia over the study period. Calls related to ENDS exposures increased nearly sixfold between 2013 and 2014 and did not decline subsequently. Exposures were most frequently documented in children aged 4 years or less (81 [43.5%]), with 58 (31.0%) in 1- and 2-year-olds. Seventy-two exposures (89%) in children aged 4 years or less were due to accidental ingestion, whereas adults aged 25 years or more called the poison centre following ENDS malfunctions (7 [23%], spills (4 [13%]) and exposure to e-juice mistaken for other substances (4 [13%]). Of the 186 exposed people, 87 (46.8%) reported symptoms. INTERPRETATION British Columbia experienced a sixfold increase in ENDS-related calls to the provincial poison centre between 2012 and 2017, driven by ingestions in young children. Regulatory approaches aimed at minimizing children's access to ENDS, clear labelling of nicotine concentration, and packaging that reduces the likelihood of spills, product confusion and malfunction should be considered.

Abstract
Although macrophages are armed with potent antibacterial functions, Mycobacterium tuberculosis (Mtb) replicates inside these innate immune cells. Determinants of macrophage intrinsic bacterial control, and the Mtb strategies to overcome them, are poorly understood. To further study these processes, we used an affinity tag purification mass spectrometry (AP-MS) approach to identify 187 Mtb-human protein-protein interactions (PPIs) involving 34 secreted Mtb proteins. This interaction map revealed two factors involved in Mtb pathogenesis-the secreted Mtb protein, LpqN, and its binding partner, the human ubiquitin ligase CBL. We discovered that an lpqN Mtb mutant is attenuated in macrophages, but growth is restored when CBL is removed. Conversely, Cbl-/- macrophages are resistant to viral infection, indicating that CBL regulates cell-intrinsic polarization between antibacterial and antiviral immunity. Collectively, these findings illustrate the utility of this Mtb-human PPI map for developing a deeper understanding of the intricate interactions between Mtb and its host.

Abstract
OBJECTIVE Anticoagulant therapy (ACT) after traumatic intracranial hemorrhage may lead to progression of hemorrhage, but in the presence of thromboembolic events, the clinician must decide if the benefits outweigh the risks. Currently, no data exist to guide therapy in the acute setting. METHODS We retrospectively identified all patients admitted to our institution with traumatic intracranial hemorrhage that received intravenous heparin, full-dose enoxaparin, or warfarin during their initial hospitalization over a 3-year period. We reviewed their demographics, hospital course, clinical indication and timing for initiation of ACT, and complications. RESULTS A total of 112 patients were identified. The median age and Glasgow Coma Scale score of these patients was 50.5 years and 9.5, respectively. Twenty-two patients required neurosurgical procedures for their presenting injury, including intracranial pressure monitors and/or open surgeries. Fifty-four patients had deep vein thrombosis or pulmonary embolism prior to initiation, and the remaining 20 patients had preexisting conditions or other indications for initiating ACT. The median time from injury to starting ACT was 8 days. Immediate complications occurred in 6 patients; however, none of these patients required a neurosurgical intervention. Delayed complications included progression of acute to chronic subdural hematoma that required intervention in 2 patients. One patient died from delayed hemorrhage. CONCLUSIONS For this patient population, the risk of immediate and delayed intracranial hemorrhages from initiating ACT therapy in intracranial injury must be weighed against the morbidity of delaying treatment. Although further studies are needed, our review provides the first rates of complications for this patient population.

Abstract
AIM To assess the immediate effect of a 60-minute oral health educational seminar for paediatric and family medicine residents in improving their knowledge, attitude, likelihoodtowards incorporating oral health preventive practice in their current practices to well-child visits, and confidence in identifying and referring patients with dental trauma. MATERIALS AND METHODS Baseline pre- and post-test design was used to evaluate the immediate effect of a 60-minute PowerPoint oral health educational seminar given to the paediatric and family medicine residents. STATISTICS Multiple-choice items were used and the pre- and post-test data were analysed with McNemar and Wilcoxon signed-rank tests. A p-value <0.05 was considered statistically significant. RESULTS Sixty-eight residents participated in the oral health educational seminar and completed the questionnaire. The mean age of participants was 29.9 years old (SD ±4.8 yrs.). Immediately following a 60-minute oral health educational seminar, there was an overall significant increase in participants' knowledge, attitudes and likelihood towards incorporating oral health preventive practice in their current practices to well-child visits (p<0.05). More confidence in identifying and referring patients with dental trauma was reported by 100% of participants. CONCLUSIONS A 60-minute oral health educational seminar was effective in improving paediatric and family medicine residents' immediate knowledge, attitude, and likelihood towards incorporating oral health preventive practice in their current practices to well-child visits. Significantly more residents felt more confident in identifying and referring patients with dental trauma. Key messages: an oral health educational seminar can be effective in improving paediatric and family medicine residents' immediate knowledge, attitude, and likelihood towards incorporating oral health preventive practice in their current practices to well-child visits.

Abstract
The occurrence of ethyl carbamate was investigated in fermented foods and alcoholic beverages of the Korean total diet study. The concentrations of ethyl carbamate ranged from not detected to 166.5 μg kg-1. Dietary exposure to ethyl carbamate was estimated by the probabilistic method. Estimated intakes of ethyl carbamate from foods and alcoholic beverages were 4.12 ng kg-1 body weight (bw) per day for average consumers and 12.37 ng kg-1 bw/day for 95th percentile high consumers. The major foods contributing to ethyl carbamate exposure were soy sauce (63%), followed by maesilju (plum liqueur, 30%), whisky (5%), and bokbunjaju (black raspberry wine, 2%). On the basis of the benchmark dose lower confidence limit 10% (BMDL10) of 0.3 mg kg-1 bw/day, margins of exposure were 128,000 for mean exposure and 40,000 for 95th percentile exposure. This indicates that the exposure of the Korean general population for ethyl carbamate is of low concern. However, careful vigilance should be continued for high consumers of fermented foods and alcoholic beverages.

Abstract
Pulse rate variability (PRV) analysis appears as the first alternative to heart rate variability analysis for wearable devices; however, there is a constraint on computational load and energy consumption for the limited system resources available to the devices. Considering that adjustment of the sampling frequency is one of the strategies for reducing computational load and power consumption, this study aimed to investigate the influence of sampling frequency (f s) on PRV analysis and to find the minimum sampling frequency while maintaining reliability. We generated 5000, 2500, 1000, 500, 250, 100, 50, 25, 20, 15, 10, 5 Hz down-sampled photoplethysmograms from 10 kHz-sampled PPGs and derived time- and frequency-domain variables of the PRV. These included AVNN, SDNN, SDSD, RMSSD, NN50, pNN50, total power, VLF, LF, HF, LF/HF, nLF and nHF for each down-sampled signal. Derived variables were compared with heart rate variability of the 10 kHz-sampled electrocardiograms, and then statistically investigated using one-way ANOVA test and Bland-Altman analysis. As a result, significant differences (P < 0.05) were found for SDNN, SDSD, RMSSD, NN50, pNN50, TP, HF, LF/HF, nLF and nHF, but not for AVNN, VLF and LF. Based on the post hoc tests, it was found that the NN50 and pNN50, SDSD and RMSSD, LF/HF and nHF, SDNN, TP and nLF analysis had significant differences at f s ⩽ 20 Hz, f s ⩽ 15 Hz, f s ⩽10 Hz; f s = 5 Hz, respectively. In other words, a significant difference was not seen for any variable if the f s was greater than 25 Hz. Consequently, our pilot study suggests that analysis of variability in the time and frequency domain from pulse rate obtained through PPG may be potentially as reliable as that derived from the analysis of the electrocardiogram, provided that f s ⩾25 Hz sampling frequency is used.

Abstract
Human retinal ganglion cells (RGCs) derived from pluripotent stem cells (PSCs) have anticipated value for human disease study, drug screening, and therapeutic applications; however, their full potential remains underdeveloped. To characterize RGCs in human embryonic stem cell (hESC) derived retinal organoids we examined RGC markers and surface antigen expression and made comparisons to human fetal retina. RGCs in both tissues exhibited CD184 and CD171 expression and distinct expression patterns of the RGC markers BRN3 and RBPMS. The retinal progenitor cells (RPCs) of retinal organoids expressed CD184, consistent with its expression in the neuroblastic layer in fetal retina. In retinal organoids CD184 expression was enhanced in RGC competent RPCs and high CD184 expression was retained on post-mitotic RGC precursors; CD171 was detected on maturing RGCs. The differential expression timing of CD184 and CD171 permits identification and enrichment of RGCs from retinal organoids at differing maturation states from committed progenitors to differentiating neurons. These observations will facilitate molecular characterization of PSC-derived RGCs during differentiation, critical knowledge for establishing the veracity of these in vitro produced cells. Furthermore, observations made in the retinal organoid model closely parallel those in human fetal retina further validating use of retinal organoid to model early retinal development.

Cleft lip and/or palate (CL/P) are common structural birth defects in humans. We used exome sequencing to study a patient with bilateral CL/P and identified a single nucleotide deletion in the patient and her similarly affected son—c.546_546delG, predicting p.Gln183Argfs*57 in the Distal-less 4 (DLX4) gene. The sequence variant was absent from databases, predicted to be deleterious and was verified by Sanger sequencing. In mammals, there are three Dlx homeobox clusters with closely located gene pairs (Dlx1/Dlx2, Dlx3/Dlx4, Dlx5/Dlx6). In situ hybridization showed that Dlx4 was expressed in the mesenchyme of the murine palatal shelves at E12.5, prior to palate closure. Wild-type human DLX4, but not mutant DLX4_c.546delG, could activate two murine Dlx conserved regulatory elements, implying that the mutation caused haploinsufficiency. We showed that reduced DLX4 expression after short interfering RNA treatment in a human cell line resulted in significant up-regulation of DLX3, DLX5 and DLX6, with reduced expression of DLX2 and significant up-regulation of BMP4, although the increased BMP4 expression was demonstrated only in HeLa cells. We used antisense morpholino oligonucleotides to target the orthologous Danio rerio gene, dlx4b, and found reduced cranial size and abnormal cartilaginous elements. We sequenced DLX4 in 155 patients with non-syndromic CL/P and CP, but observed no sequence variants. From the published literature, Dlx1/Dlx2 double homozygous null mice and Dlx5 homozygous null mice both have clefts of the secondary palate. This first finding of a DLX4 mutation in a family with CL/P establishes DLX4 as a potential cause of human clefts.

Abstract
We used exome sequencing to study a non-consanguineous family with two children who had anterior segment dysgenesis, sclerocornea, microphthalmia, hypotonia and developmental delays. Sanger sequencing verified two Peroxidasin (PXDN) mutations in both sibs--a maternally inherited, nonsense mutation, c.1021C>T predicting p.(Arg341*), and a paternally inherited, 23-basepair deletion causing a frameshift and premature protein truncation, c.2375_2397del23, predicting p.(Leu792Hisfs*67). We re-examined exome data from 20 other patients with structural eye defects and identified two additional PXDN mutations in a sporadic male with bilateral microphthalmia, cataracts and anterior segment dysgenesis--a maternally inherited, frameshift mutation, c.1192delT, predicting p.(Tyr398Thrfs*40) and a paternally inherited, missense substitution that was predicted to be deleterious, c.947 A>C, predicting p.(Gln316Pro). Mutations in PXDN were previously reported in three families with congenital cataracts, microcornea, sclerocornea and developmental glaucoma. The gene is expressed in corneal epithelium and is secreted into the extracellular matrix. Defective peroxidasin has been shown to impair sulfilimine bond formation in collagen IV, a constituent of the basement membrane, implying that the eye defects result because of loss of basement membrane integrity in the developing eye. Our finding of a broader phenotype than previously appreciated for PXDN mutations is typical for exome-sequencing studies, which have proven to be highly effective for mutation detection in patients with atypical presentations. We conclude that PXDN sequencing should be considered in microphthalmia with anterior segment dysgenesis.

Abstract
When making decisions under uncertainty, the optimal choices are often difficult to discern, especially if not enough information has been gathered. Two key questions in this regard relate to whether one should stop the information gathering process and commit to a decision (stopping criterion), and if not, what information to gather next (selection criterion). In this paper, we show that the recently introduced notion, Same-Decision Probability (SDP), can be useful as both a stopping and a selection criterion, as it can provide additional insight and allow for robust decision making in a variety of scenarios. This query has been shown to be highly intractable, being PP^PP-complete, and is exemplary of a class of queries which correspond to the computation of certain expectations. We propose the first exact algorithm for computing the SDP, and demonstrate its effectiveness on several real and synthetic networks. Finally, we present new complexity results, such as the complexity of computing the SDP on models with a Naive Bayes structure. Additionally, we prove that computing the non-myopic value of information is complete for the same complexity class as computing the SDP.

Abstract
We developed a series of models for the label decay in cell proliferation assays when the intracellular dye carboxyfluorescein succinimidyl ester (CFSE) is used as a staining agent. Data collected from two healthy patients were used to validate the models and to compare the models with the Akiake Information Criteria. The distinguishing features of multiple decay rates in the data are readily characterized and explained via time dependent decay models such as the logistic and Gompertz models.

Abstract
The major active retinoid, all-trans retinoic acid, has long been recognized as critical for the development of several organs, including the eye. Mutations in STRA6, the gene encoding the cellular receptor for vitamin A, in patients with Matthew-Wood syndrome and anophthalmia/microphthalmia (A/M), have previously demonstrated the importance of retinol metabolism in human eye disease. We used homozygosity mapping combined with next-generation sequencing to interrogate patients with anophthalmia and microphthalmia for new causative genes. We used whole-exome and whole-genome sequencing to study a family with two affected brothers with bilateral A/M and a simplex case with bilateral anophthalmia and hypoplasia of the optic nerve and optic chiasm. Analysis of novel sequence variants revealed homozygosity for two nonsense mutations in ALDH1A3, c.568A>G, predicting p.Lys190*, in the familial cases, and c.1165A>T, predicting p.Lys389*, in the simplex case. Both mutations predict nonsense-mediated decay and complete loss of function. We performed antisense morpholino (MO) studies in Danio rerio to characterize the developmental effects of loss of Aldh1a3 function. MO-injected larvae showed a significant reduction in eye size, and aberrant axonal projections to the tectum were noted. We conclude that ALDH1A3 loss of function causes anophthalmia and aberrant eye development in humans and in animal model systems.

Abstract
OBJECTIVE To examine the demographic and psychopathological characteristics of the treatment discontinuation group compared with patients who completed with paliperidone ER treatment for 6 months. METHODS A total of 984 patients meeting the DSM-IV criteria for schizophrenia who switched their antipsychotics were recruited from 61 sites in five countries in Southeast Asia. The patients with early discontinuation were then compared with those who completed the 6-month treatment in terms of demographic and psychopathological variables at baseline and also at the end of the evaluation period, which included PANSS score, sleep quality, daytime drowsiness, PSP score, ESRS score and clinical global impression-severity (CGI-S) score. Finally, logistic regression analysis was applied to determine predictive factors that were associated with discontinuation. RESULTS Of 984 patients, 284 patients (28.9%) discontinued without completing the 6-month treatment period with paliperidone. Significant differences in patient baseline characteristics for the discontinuation group compared with the completion group were observed for gender, number of previous hospitalisations with psychosis, PANSS total score and all of its subscales, daytime drowsiness score, total ESRS score, CGI-S, PSP and Insight. Patients who completed the study period had significantly better scores in all psychopathology variables compared with the discontinuation group at the end of the evaluation period. Numbers of previous hospitalisations because of psychosis, being exposed with first generation antipsychotics, gender and PANSS total scores were found to be significant predictors of discontinuation. CONCLUSION Patients who discontinued early from a 6-month treatment period with Paliperidone have some characteristic differences compared with completion patients. Many factors including frequent hospitalisations, female gender, high PANSS score (indicating more disease severity) and previous exposure to first generation of antipsychotic agent might lead patients to discontinue from treatment.
