Abstract
Background Individualized treatment for commercial tobacco smoking cessation, such as through the utilization of the nicotine metabolite ratio (NMR), offers substantial clinical benefit. NMR is a metabolism-informed biomarker that can be used to guide medication selection. NMR testing is particularly promising for tobacco cessation efforts in populations with high rates of smoking, such as some Alaska Native and American Indian (AN/AI) communities. To date, no prior study has evaluated the implementation of NMR-guided tobacco cessation with AN/AI populations. Methods The present "QUIT" protocol is a two-phase study that will occur at Southcentral Foundation (SCF), an Alaska Native-owned health system, serving 70,000 AN/AI people, based in Anchorage, Alaska. In Phase one, qualitative interviews with customer-owners (patients), providers and administrators (n = 36) and a 10-participant beta-test will be used to refine a strategy to implement NMR testing in the health system. Phase two will involve a single-arm pilot trial (n = 50) and qualitative interviews throughout data collection (n = 48) to evaluate the implementation strategy and explore the real-world acceptability and feasibility of NMR testing to guide tobacco cessation with AN/AI populations. Discussion This study utilizes a community-based participatory approach to refine and implement a nicotine metabolism-informed smoking cessation program in a Tribal healthcare setting. The process and findings from this study will reflect the importance of customer-owner choice and honor the lived experience involved in quitting commercial tobacco. Pilot study data will inform the effect and sample sizes required for a future pragmatic trial of NMR-guided smoking cessation.

Abstract
Anxiety disorders are among the most common psychiatric disorders in the general population. Our objective was to describe the cumulative incidence and risk factors of anxiety disorders, including obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD), in a follow-up of young adults over a five-year period. This is a prospective cohort conducted in two waves. The first took place from 2007 to 2009, in which 1,560 young adults aged between 18 and 24 years were evaluated using the Mini-International Neuropsychiatric Interview (MINI). Subjects were invited to participate in the second wave, which wave took place from 2012 to 2014, where 1,244 young adults were evaluated using the MINI-Plus. Our findings showed a cumulative incidence of 10.9% for any anxiety disorder, 6.5% for generalized anxiety disorder, 6.0% for agoraphobia, 2.0% for OCD, 1.6% for panic disorder, 1.1% for social anxiety and 0.7% for PTSD. Being female and having had a depressive episode were risk factors to develop any anxiety disorder. We observed a high cumulative incidence of anxiety disorders in a population-based sample of young adults. Our data highlights the importance of the early identification of these disorders as this could lead to early illness detection, early illness management and a reduced burden of disease.

Abstract
This study was a secondary data analysis of factors associated with alcohol-related child removal among American Indian/Alaska Native (AI/AN) adults enrolled in a clinical trial of an alcohol intervention. Among 326 parent participants, 40% reported ever having a child removed from their care in part because of the parent's alcohol use, defined here as alcohol-related child removal. Seventy-five percent of parents reported at least one separation during their own childhood (M = 1.3, SD = 1.0). In a multivariable analysis, alcohol-related child removal was associated with parental boarding school attendance. No relationship was found between alcohol-related child removal and alcohol intervention outcomes. Results may provide evidence of multigenerational child removal impacts of boarding schools on AI/AN adults receiving an alcohol use disorder intervention. Assessment of parental history of child removal by practitioners, strategies to prevent alcohol-related separation and to support reunification should be integrated into addiction treatment in AI/AN communities.

Abstract
Suicide disproportionately affects many American Indian/Alaska Native (AI/AN) communities. Caring Contacts is one of the few suicide prevention interventions with demonstrated success in diverse populations, but its acceptability and effectiveness have not been evaluated in AI/AN communities. Using community-based participatory research (Phase 1), we conducted focus groups and semi-structured interviews with AI/AN adults, healthcare providers, and leaders in four communities to improve study design and maximize intervention acceptability and effectiveness for implementation in a randomized controlled trial (Phase 2). This paper describes how adaptations made during Phase 1 affected the acceptability, fit, and responsiveness of the study features to the communities' needs. Acceptability of the study procedures and materials in this community appears to be high, with 92% of participants indicating the initial assessment interview was a positive experience. Broadening eligibility criteria with regard to age and possession of a cellular device resulted in the recruitment of an additional 48% and 46% of participants, respectively. Inclusion of locally-informed methods of self-harm allowed us to capture a wider range of suicidal behavior than would have otherwise been identified. Clinical trials would benefit from community-engaged, cultural adaptation studies with populations in which the interventions would eventually be applied.

Abstract
OBJECTIVE The aim of the study is to investigate clinically meaningful, secondary outcomes in a randomized trial of a culturally adapted contingency management (CM) intervention for alcohol use in 3 diverse American Indian and Alaska Native communities. METHODS Three American Indian and Alaska Native communities located in the Northern Plains, Alaska, and the Inland Northwest were partnering sites. A total of 158 individuals were randomized to either a 12-week CM intervention or a noncontingent (NC) control group. The CM group received reinforcers for providing alcohol-negative ethyl glucuronide (EtG < 150 ng/mL) urine samples, while the NC group received reinforcers unconditionally. Outcomes included EtG as a continuous measure (range, 0-2,000 ng/mL), EtG > 499 ng/mL (a measure of higher levels of recent alcohol use), longest duration of abstinence, and time-to-first alcohol-positive EtG during the trial. Generalized estimating equations along with Cox proportional hazard and negative binomial regressions were used. RESULTS Participants randomized to the CM group had lower mean EtG levels (-241.9 ng/mL; 95% confidence interval [CI], -379.0 to -104.8 ng/mL) and 45.7% lower odds (95% CI, 0.31 to 0.95) of providing an EtG sample indicating higher levels of alcohol use during the intervention. Longest duration of abstinence was 43% longer for the CM group than the NC group (95% CI, 1.0 to 1.9). Risk of time-to-first drink during treatment did not differ significantly. CONCLUSIONS These secondary outcome analyses provide evidence that CM is associated with reductions in alcohol use and longer durations of abstinence (as assessed by EtG), both clinically meaningful endpoints and analyses that differ from the primary study outcome.

Abstract
Abstract
Introduction
Patients with pulmonary arterial hypertension (PAH) following congenital heart disease (CHD) repair are an emerging population at increased risk of complications. Small numbers of such patients have been included in studies evaluating the efficacy of macitentan, but since obtaining a license for use in this population, limited real-world data have been published.
Purpose
To describe the safety and efficacy of macitentan therapy in a population of adults with repaired PAH-CHD.
Methods
We conducted a retrospective observational study of patients with repaired PAH-CHD newly started on macitentan in 2 UK specialist centres between 2014 and 2020. Clinical variables, including WHO functional class (FC), 6-minute walk (6MW) or incremental shuttle walk (ISW) distance, and EMPHASIS-10 score were recorded prior to and after initiation of macitentan therapy.
Results
Overall, 49 patients were included, 63.3% female, median age 40.8 [26.7–53.7] years at initiation of macitentan therapy. Macitentan was started as part of the initial PAH therapeutic regimen in 18 (36.7%) and was an add-on to existing therapy in 31 (63.3%) patients, of whom over a third (35.5%) were switched from another endothelin receptor antagonist. At the time of therapy initiation, most patients (68.4%) were in WHO functional class (FC) III, while 26.3% were in FC II and 5.3% in FC I. Baseline 6-minute walk distance (n=31, 72.1%) was 355.0 [263.5–461.2] m and incremental shuttle walk distance (n=12, 27.9%) was 220.0 [175.0–302.5] m. EMPHASIS-10 score (n=39) was 24 [10–36]. After 12.7 [9.8–16.1] months of macitentan therapy, objective exercise capacity improved by 11.8 [−4.3–36.9]% (p=0.01). Health-related quality of life improved by at least 5 points in 41.9% of patients, but there was no significant change in quality of life score in the overall group (0.0 [−20.3–18.1]% change, p=0.78). Macitentan therapy was stopped in 4 (8.2%) patients due to an adverse event or patient choice, and 5 (10.2%) due to clinical worsening or absence of clinical improvement. At 1 year following macitentan initiation, 6 (12.2%) patients had been further escalated to triple therapy and 5 (10.2%) had died.
Conclusions
Patients with repaired PAH-CHD treated with macitentan in the UK are a highly symptomatic group with limited exercise tolerance. Macitentan was well-tolerated overall and led to a significant improvement in objective exercise capacity.

Abstract
Abstract
Introduction
Pulmonary arterial hypertension (PAH) is a common complication of congenital heart disease (CHD). PAH following CHD repair (repaired PAH-CHD) is an emerging population with increased morbidity and mortality [1–3]. Risk scores that are widely used in the adult PAH population have not been validated and may not be applicable in young children with repaired PAH-CHD.
Purpose
To characterize the 20-year cohort of the UK National Paediatric PH Service, focusing on peri-operative characteristics and outcomes of children with repaired PAH-CHD, and develop a tailored risk stratification tool.
Methods
We included consecutive children presenting to our specialist service between 2001 and 2021 with a diagnosis of repaired PAH-CHD. Patients with univentricular physiology, segmental pulmonary hypertension (PH), and PH primarily due to abnormal development of the pulmonary vasculature were excluded. Univariable Cox regression analysis was performed in children with PAH present ≥3 months after CHD repair, with an outcome of death or transplantation. Time-dependent ROC analysis was used to evaluate the risk model.
Results
Overall, 178 patients were included (age 3.2 [1.3–7.9] years, 58.4% female). Most children (73.0%) were referred following CHD repair. Complex CHD was present in 61.2%, and 48.9% had combined pre- and post-tricuspid shunts. Down syndrome was present in 33.1%. At the first post-operative PH assessment, 53.1% of patients had symptoms, mainly breathlessness. On echocardiographic evaluation, 30.9% had moderate-severe right ventricular dilatation and 23.7% had right ventricular systolic impairment. Over a median follow-up of 6.0 [2.4–11.0] years, 30 (19.2%) patients died and 5 (3.2%) patients underwent lung transplantation. Transpant-free survival at 1, 5, and 10 years was 94.7% (95% CI: 91.2–98.3%), 85.9% (95% CI: 80.3–91.9%), and 80.1% (95% CI: 73.1–87.7%), respectively. Cox analysis identified several clinical variables associated with death or transplantation, of which the following variables assessed post-repair were used to develop the risk score: absence of pre-operative PH, breathlessness, right ventricular dysfunction, and pulmonary vascular resistance index >14 WU m2 or lesion at high risk of causing PH (Figure 1). This novel, simple risk score performed well (AUC >80% at 1, 3, 5 and 10 years) and was well-calibrated in our cohort (Figure 2, D'Agostino-Nam p=0.76).
Conclusions
In this national cohort of children with repaired PAH-CHD, mortality is significant. This novel, simple risk score performed well in our population and could be used in clinical practice at the time of post-operative assessment to predict outcome and direct management but requires further validation.

Abstract
OBJECTIVE Determine whether a culturally tailored contingency management (CM) intervention targeting alcohol abstinence resulted in secondary effects on cannabis use among American Indian and Alaska Native (AI/AN) adults. METHODS The research team conducted this secondary data analysis to examine cannabis abstinence using data from a randomized control trial of CM for alcohol use among three AI/AN-serving organizations. One hundred and fifty-eight adults met the randomization criteria (i.e., submission of 50% or more urine samples and one alcohol-positive urine test during a 4-week, pre-randomization, observation period). For 12 weeks after randomization, participants received incentives for submitting a urine test negative for ethyl glucuronide (EtG < 150 ng/mL, CM group) or incentives for submitting a urine sample regardless of abstinence (Non-contingent [NC] Control group). Generalized linear mixed effects models assessed group differences in cannabis abstinence during the intervention, verified by urine tetrahydrocannabinol negative tests (11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid <50 ng/mL). RESULTS At baseline, 42.2% (n = 35) of participants in the NC group and 40.0% (n = 30) of those in the CM group had a cannabis positive urine test. An overall intervention by time interaction was detected for a cannabis negative urine test (χ2 = 13.40, p = 0.001). Compared to the NC group, the CM group had 3.92 (95% CI:1.23-12.46) times higher odds of having a cannabis negative urine test during the intervention period and 5.13 (95% CI:1.57-16.76) times higher odds of having a negative cannabis test at the end of intervention period. CONCLUSION CM addressing alcohol misuse may be an effective strategy for decreasing cannabis use among AI/AN adults. TRIAL REGISTRATION ClinicalTrials.gov number, Identifier: NCT02174315.

Abstract
A 56-year-old man was referred by his dentist to an orthodontist as part of an interdisciplinary treatment plan for a complete dental rehabilitation. The patient presented with a mutilated dentition with a restricted envelope of function and generalized severe tooth wear with loss of vertical dimension. The patient showed a history of multiple endodontically treated and subsequently extracted elements associated with unexplained symptoms until a neurologist diagnosed trigeminal neuralgia. The orthodontic treatment in which the restricted envelope of function was eliminated and the vertical dimension was reestablished resulted in a significant reduction of the number of triggers experienced by the patient.

Abstract
Children with epilepsy have more sleep disorders compared to healthy children. The bidirectional interaction between epilepsy and sleep is not completely understood. However, disruption of sleep architecture during childhood may have consequences for cognitive development. As children with drug-refractory epilepsy often have intellectual disability, sleep disruption could be an important contributing factor in severity of their cognitive impairment. To better understand these interactions, sleep architecture in children with drug-refractory epilepsy and epileptic encephalopathies should be investigated. In this review, we conducted a systematic literature search on this topic. Articles that investigated sleep macro- and/or microstructure by means of electroencephalogram/polysomnography were included, as well as articles that used validated questionnaires. Sixteen articles were reviewed, eight of which used polysomnography. Only 2 articles examined sleep in children with epileptic encephalopathies. Consistent findings on measures of sleep architecture were a reduction in REM percentage and an increase in sleep fragmentation when comparing drug-refractory patients with non-refractory and healthy subjects. The findings on slow wave sleep were less clear. Studies with questionnaires unambiguously confirmed subjectively more sleep problems in children with drug-refractory epilepsy. This is the first review of literature in this patient population. More good quality sleep studies in children with drug-refractory epilepsy are warranted. The use of wearables in the home setting together with automatic sleep staging could provide more insights.

Abstract
We review two algorithmic advances that bring us closer to reliable quantum simulations of model systems in high-energy physics and beyond on noisy intermediate-scale quantum (NISQ) devices. The first method is the dimensional expressivity analysis of quantum circuits, which allows for constructing minimal but maximally expressive quantum circuits. The second method is an efficient mitigation of readout errors on quantum devices. Both methods can lead to significant improvements in quantum simulations, e.g. when variational quantum eigensolvers are used. This article is part of the theme issue 'Quantum technologies in particle physics'.

Abstract
Abstract
Introduction/Objective
Introduction: DOG1 (Discovered on GIST1) is a voltage-gated calcium-activated chloride and bicarbonate channel that is highly expressed in interstitial cells of Cajal and in gastrointestinal stromal tumors (GIST) derived from Cajal cells.
Methods/Case Report
Methods: To systematically determine in what tumor entities and normal tissue types DOG1 may be further expressed, a tissue microarray (TMA) containing 15,965 samples from 121 different tumor types and subtypes as well as 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry.
Results (if a Case Study enter NA)
Results: DOG1 immunostaining was found in 67 tumor types including GIST (95.7%), esophageal squamous cell carcinoma (31.9%), pancreatic ductal adenocarcinoma (33.6%), adenocarcinoma of the Papilla Vateri (20%), squamous cell carcinoma of the vulva (15.8%) and the oral cavity (15.3%), mucinous ovarian cancer (15.3%), esophageal adenocarcinoma (12.5%), endometrioid endometrial cancer (12.1%), neuroendocrine carcinoma of the colon (11.1%) and diffuse gastric adenocarcinoma (11%). Low level-DOG1 immunostaining was seen in 17 additional tumor entities. DOG1 expression was unrelated to histopathological parameters of tumor aggressiveness and/or patient prognosis in cancers of the breast (n=1,002), urinary bladder (975), ovary (469), endometrium (173), stomach (233), and thyroid gland (512).
Conclusion
High DOG1 expression was linked to estrogen receptor expression in breast cancer (p<0.0001) and absence of HPV infection in squamous cell carcinomas (p=0.0008). In conclusion, our data identify several tumor entities that can show DOG1 expression levels at similar levels as in GIST. Although DOG1 is tightly linked to a diagnosis of GIST in spindle cell tumors, the differential diagnosis is much broader in DOG1 positive epithelioid neoplasms.

Abstract
Variational quantum eigensolvers (VQEs) combine classical optimization with efficient cost function evaluations on quantum computers. We propose a new approach to VQEs using the principles of measurement-based quantum computation. This strategy uses entangled resource states and local measurements. We present two measurement-based VQE schemes. The first introduces a new approach for constructing variational families. The second provides a translation of circuit- to measurement-based schemes. Both schemes offer problem-specific advantages in terms of the required resources and coherence times.

Abstract
Importance Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders. Objective To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition. Design, Setting, and Participants This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020. Interventions Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period. Main Outcomes and Measures Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL). Results Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03). Conclusions and Relevance The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders.

Abstract
OBJECTIVE Our goal was to present 2 decades of our experience with the Ross procedure and its sequential modifications, adopted since 2010, to improve the reoperation rate. METHODS We performed a single-centre, retrospective review of database information and medical notes about the implantation technique: the freestanding root. We compared era 1 (1997-2009) and era 2 (2010-2019). RESULTS Between 1997 and 2019, a total of 214 Ross procedures were performed (71% men, median age 24 years) [interquartile range (IQR) 15-38]. Of these, 87% had various forms of congenital-dysplastic aortic valves. The median cross-clamping and bypass times were 173 (IQR 148-202) and 202 (IQR 182-244) min. The median postoperative stay was 6 days (2-77). Thirty-day mortality was 0.5%. The median follow-up time was 8.2 years (IQR 3.9-13.2). Survival at 10 and 20 years was 97% and 95%; freedom from greater than moderate aortic regurgitation or aortic valve intervention was 91% and 80%; and 93% of the patients were in New York Heart Association functional class I. Twenty (21%) patients operated on during era 1 and 6 (9%) during era 2 underwent autograft reoperations. The median follow-up time was 14.3 (IQR 11.5-17.4) and 4.8 (IQR 2.5-7) years. Freedom from autograft reoperation was 87% and 69% at 10 and 20 years, with no significant difference between eras. Freedom from homograft reoperation was 96% and 76% at 10 and 20 years. The presence of aortic regurgitation, infective endocarditis and era 1 were predictors of autograft reoperation. Male gender and era 1 were predictors of neoaortic root dilatation. CONCLUSIONS The contemporary modified Ross procedure continues to deliver excellent results and should remain part of the strategy to treat children and young adults requiring aortic valve replacement.

Abstract
Abstract
Introduction
The Fontan circulation is successful in abolishing cyanosis and chronic volume overload in congenital heart disease (CHD) patients with single ventricle physiology. “Fontan failure” is a major cause of poor quality of life and mortality in these patients. Recently, pulmonary arterial hypertension (PAH) therapies have been used in Fontan patients with variable success, even though patients included in these studies are generally at the best end of the spectrum.
Aim
To assess contemporary patterns of PAH therapy in Fontan patients in large specialist CHD centres.
Methods
We identified all adult patients with a Fontan-type circulation under active follow-up in 8 specialist CHD centres between 2009 and 2019. Patients on PAH therapies were matched by age and gender to untreated patients (1:1 or 1:2). Baseline data were collated immediately prior to initiation of therapy (treated group) or from a synchronous routine clinical assessment (untreated group).
Results
During the study period, 70 Fontan patients were started on PAH therapy (6.5% of those under follow-up). The majority 63 (90.0%) were started on monotherapy with a phosphodiesterase-5 (PDE5) inhibitor, 6 (8.6%) patients were started on an endothelin receptor antagonist (ERA) and 1 (1.4%) received early sequential therapy with a PDE5 inhibitor and ERA. Prostacyclin analogues were not used, and no patients received triple therapy. Overall, 51 (72.9%) patients started therapy electively (49% in outpatient clinic, 51% as day case admission), while 18 (25.7%) were treated following urgent hospital admission with fluid overload +/− acute kidney injury. The remainder (2,2.9%) started therapy following cardiac surgery. Adverse events during treatment were rare. Patients starting PAH therapy were matched to 112 untreated patients (table 1). Patients were well matched between groups for age (p=0.52) and sex (p=0.27). Treated patients were more likely to be significantly impaired than matched patients (56.7% vs. 8.6% in NYHA class III/IV, p<0.0001) and were more likely to have ascites (16.2% vs. 0.9%, p=0.0002). Treated patients were also more likely to have a lower albumin level (43 [14–56] vs. 45 [29–54], p=0.01) or to be on a loop diuretic e.g. furosemide (p<0.0001), at a higher daily dose (p<0.0001) than matched patients. Only a quarter of patients on therapies had no high-risk features (24.2%), 80% of whom were from a single centre.
Conclusion
A small minority of Fontan patients followed in specialist centres receive PAH therapies. PAH therapy was reserved in most centres for patients with more advanced disease, targeting predominantly those with a “failing Fontan” in an individualised approach, in line with the recent adult CHD American Heart Association (AHA) guidelines. Further studied are needed to establish the role of PAH therapies in Fontan patients, provided that adult patients with advanced disease who are at increased risk of adverse outcome are included.

Abstract
OBJECTIVE Early experience of pain and stress in the neonatal intensive care unit is known to have an effect on the neurodevelopment of the infant. However, an automated method to quantify the procedural pain or perinatal stress in premature patients does not exist. APPROACH In the current study, EEG and ECG data were collected for more than 3 hours from 136 patients in order to quantify stress exposure. Specifically, features extracted from the EEG and heart-rate variability in both quiet and non-quiet sleep segments were used to develop a subspace linear-discriminant analysis stress classifier. MAIN RESULTS The main novelty of the study lies in the absence of intrusive methods or pain elicitation protocols to develop the stress classifier. Three main findings can be reported. First, we developed different stress classifiers for the different age groups and stress intensities, obtaining an area under the curve in the range [0.78-0.93] for non-quiet sleep and [0.77-0.96] for quiet sleep. Second, a dysmature EEG was found in patients under stress. Third, an enhanced cortical connectivity and increased brain-heart communication was correlated with a higher stress load, while the autonomic activity did not seem to be associated to stress exposure. SIGNIFICANCE The results shed a light on the pain and stress processing in preterm neonates, suggesting that software tools to investigate dysmature EEG might be helpful to assess stress load in premature patients. These results could be the foundation to assess the impact of stress on infants' development and to tune preventive care.

Abstract
Early life stress in the neonatal intensive care unit (NICU) predisposes premature infants to adverse health outcomes. Although those patients experience frequent apneas and sleep-wake disturbances during their hospital stay, clinicians still rely on clinical scales to assess pain and stress burden. This study addresses the relationship between stress and apneic spells in NICU patients to implement an automatic stress detector. EEG, ECG and SpO2 were recorded from 40 patients for at least 3 hours and the stress burden was assessed using the Leuven Pain Scale. Different logistic regression models were designed to detect the presence or the absence of stress based on the signals reactivity to each apneic spell. The classification shows that stress can be detected with an area under the curve of 0.94 and a misclassification error of 19.23%. These results were obtained via SpO2 dips and EEG regularity. These findings suggest that stress deepens the physiological reaction to apneas, which could ultimately impact the neurological and behavioral development.

Abstract
We introduce a variant of the Hybrid Monte Carlo (HMC) algorithm to address large-deviation statistics in stochastic hydrodynamics. Based on the path-integral approach to stochastic (partial) differential equations, our HMC algorithm samples space-time histories of the dynamical degrees of freedom under the influence of random noise. First, we validate and benchmark the HMC algorithm by reproducing multiscale properties of the one-dimensional Burgers equation driven by Gaussian and white-in-time noise. Second, we show how to implement an importance sampling protocol to significantly enhance, by orders of magnitudes, the probability to sample extreme and rare events, making it possible to estimate moments of field variables of extremely high order (up to 30 and more). By employing reweighting techniques, we map the biased configurations back to the original probability measure in order to probe their statistical importance. Finally, we show that by biasing the system towards very intense negative gradients, the HMC algorithm is able to explore the statistical fluctuations around instanton configurations. Our results will also be interesting and relevant in lattice gauge theory since they provide unique insights into reweighting techniques.

Abstract
OBJECTIVE To assess the neurodevelopmental outcome of children with spina bifida aperta (SBA) treated prenatally as compared to those treated postnatally. METHODS We performed a systematic review of the literature in PubMed/MEDLINE, EMBASE, Web of Science and The Cochrane Library, comparing the neurological outcome of infants with SBA treated prenatally vs postnatally. Only randomized controlled trials (RCTs) and non-randomized prospective controlled studies were included. The primary outcome assessed was neurodevelopmental impairment at the age of 1 year or later. Secondary outcomes were preterm birth, need for ventriculoperitoneal (VP) shunt by 12 months of age, absence of signs of hindbrain herniation at the first postnatal magnetic resonance imaging (MRI) evaluation and independent ambulation evaluated at 30 months. RESULTS Of 11 359 studies identified through the electronic search, six met the inclusion criteria and were assessed in full text and two, one RCT and one prospective cohort study, were ultimately included in the meta-analysis. Sensitivity analysis did not show any difference between the outcomes of the RCT alone and those of the pooled RCT and prospective cohort study. This allowed neurodevelopmental assessment of 213 children between 14 and 53 months of age. Neurodevelopment was assessed by the Bayley Scales of Infant Development II (BSID-II) mental development index corrected for chronological age, with a cut-off of ≥ 70 (representing no more than 2 SD below the mean). The presence of neurodevelopmental impairment was similar between children who underwent prenatal (25/105 (23.8%)) and those who had postnatal (30/108 (27.8%)) repair of SBA (odds ratio (OR), 0.82 (95% CI, 0.43-1.56); P = 0.54), although the risk of prematurity was higher in the prenatal-repair group (OR, 17.62 (95% CI, 7.60-40.87); P < 0.0001). For every two fetuses operated on before birth, there was, compared with those operated on after birth, one additional premature birth (number needed to harm = 2 (95% CI, 1-3)). The need for VP shunt placement by 12 months of age was lower in the prenatal-repair group (45/109 (41.3%)) than in children that had postnatal repair (93/112 (83.0%); OR, 0.14 (95% CI, 0.08-0.26); P < 0.0001). Data on neurodevelopmental impairment in children with a shunt were available only for patients from the prenatal-surgery group of the RCT; in this subgroup, the likelihood for impairment was similar between children who did (7/39 (17.9%)) and those who did not (4/48 (8.3%)) have shunt placement (P = 0.21). At first postnatal MRI evaluation, no signs of hindbrain herniation were detected in 28/88 (31.8%) children who were operated on prenatally compared with 4/89 (4.5%) who had postnatal repair (OR, 9.45 (95% CI, 3.12-28.64); P < 0.0001). Independent ambulation at 30 months was achieved by 41/109 (37.6%) children who underwent prenatal repair compared with 21/111 (18.9%) who had postnatal repair (OR, 2.59 (95% CI, 1.39-4.86); P = 0.003). CONCLUSION The risk of neurodevelopmental impairment in infants with SBA was similar between those who underwent prenatal and those who had postnatal surgical repair, despite an increased risk of prematurity in the prenatally repaired group.

Young adults (18-24 years old) were recruited and followed up on 5 years later; people were interviewed at their homes. Suicidality, as well as mood and anxiety disorders, was assessed using the Mini-International Neuropsychiatric Interview. The impact of mood episodes on suicidality was both evaluated when they occurred in the same wave (a current episode) and when suicidality occurred prospectively, with suicidality measured at follow-up (a past episode). RESULTS The sample included 1560 young adults at baseline, with 1244 reassessed at follow-up (80.6%). Depressive episodes, both current and past, had a significant impact on suicidality in the final multivariable model. Manic episodes, however, were less consistently associated with suicidality. CONCLUSION Depressive episodes have a strong, independent, and robust association with prospective suicidality. The association between manic episodes and suicidality, on the other hand, was dependent on the analysis and deserves further exploration.

Abstract
We determine within lattice QCD the nucleon spin carried by valence and sea quarks and gluons. The calculation is performed using an ensemble of gauge configurations with two degenerate light quarks with mass fixed to approximately reproduce the physical pion mass. We find that the total angular momentum carried by the quarks in the nucleon is J_{u+d+s}=0.408(61)_{stat}(48)_{syst} and the gluon contribution is J_{g}=0.133(11)_{stat}(14)_{syst}, giving a total of J_{N}=0.54(6)_{stat}(5)_{syst} that is consistent with the spin sum. For the quark intrinsic spin contribution, we obtain 1/2ΔΣ_{u+d+s}=0.201(17)_{stat}(5)_{syst}. All quantities are given in the modified minimal subtraction scheme at 2 GeV. The quark and gluon momentum fractions are also computed and add up to ⟨x⟩_{u+d+s}+⟨x⟩_{g}=0.804(121)_{stat}(95)_{syst}+0.267(12)_{stat}(10)_{syst}=1.07(12)_{stat}(10)_{syst}, thus satisfying the momentum sum.

Abstract
This study investigates the multifractal formalism framework for quiet sleep detection in preterm babies. EEG recordings from 25 healthy preterm infants were used in order to evaluate the performance of multifractal measures for the detection of quiet sleep. Results indicate that multifractal analysis based on wavelet leaders is able to identify quiet sleep epochs, but the classifier performances seem to be highly affected by the infant's age. In particular, from the developed classifiers, the lowest area under the curve (AUC) has been obtained for EEG recordings at very young age (≤ 31 weeks post-menstrual age), and the maximum at full-term age (≥ 37 weeks post-menstrual age). The improvement in classification performances can be due to a change in the multifractality properties of neonatal EEG during the maturation of the infant, which makes the EEG sleep stages more distinguishable.

Abstract
OBJECTIVE To assess the prevalence of childhood trauma and types of trauma on mood disorders among young adults in a population-based sample. We further gathered data on family history of mood disorders to test the hypothesis that childhood trauma is a mediating factor for the association between family history of mood disorder and mood disorder in adulthood. METHOD This is a cross-sectional study, including young adults with bipolar disorder, major depressive disorder, and matched controls without any mood disorder. Childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). The Hicks and Tingley implementation was employed to assess whether trauma is a mediator of the effect of family history on diagnosis of any mood disorder. RESULTS All types of trauma were associated with both major depression and bipolar disorder, with the exception of sexual abuse, which was only associated with bipolar disorder. Moreover, family history of psychiatric illness was also associated with mood disorder in adulthood and with childhood trauma. Using the presence of any mood disorder as the outcome, a third of the effect of having any family history of mood disorder was mediated via childhood trauma. CONCLUSION This investigation provides further support, in a population-based sample of young adults, of the association between childhood trauma and mood disorders, with sexual abuse being specifically linked with bipolar disorder. The hypothesis that childhood trauma would function as a partial mediator of the association between family history of mood disorder and mood disorder in adulthood was also confirmed.

Abstract
We evaluate the light, strange, and charm scalar content of the nucleon using one lattice QCD ensemble generated with two degenerate light quarks with mass fixed to their physical value. We use improved techniques to evaluate the disconnected quark loops to sufficient accuracy to determine the strange and charm nucleon σ terms in addition to the light quark content σ_{πN}. We find σ_{πN}=37.2(2.6)(4.7/2.9) MeV, σ_{s}=41.1(8.2)(7.8/5.8) MeV, and σ_{c}=79(21)(12/8) MeV, where the first error is statistical and the second is the systematic error due to the determination of the lattice spacing, the assessment of finite volume, and residual excited state effects.

Abstract
OBJECTIVES We apply the suppression curve (SC) as an automated approach to describe the maturational change in EEG discontinuity in preterm infants. This method allows to define normative values of interburst intervals (IBIs) at different postmenstrual ages (PMA). METHODS Ninety-two multichannel EEG recordings from 25 preterm infants (born ⩽32weeks) with normal developmental outcome at 9months, were first analysed using the Line Length method, an established method for burst detection. Subsequently, the SC was defined as the 'level of EEG discontinuity'. The mean and the standard deviation of the SC, as well as the IBIs from each recording were calculated and correlated with PMA. RESULTS Over the course of development, there is a decrease in EEG discontinuity with a strong linear correlation between the mean SC and PMA till 34weeks. From 30weeks PMA, differences between discontinuous and continuous EEG become smaller, which is reflected by the decrease of the standard deviation of the SC. IBIs are found to have a significant correlation with PMA. CONCLUSIONS Automated detection of individual maturational changes in EEG discontinuity is possible with the SC. These changes include more continuous tracing, less amplitude differences and shorter suppression periods, reflecting development of the vigilance states. SIGNIFICANCE The suppression curve facilitates automated assessment of EEG maturation. Clinical applicability is straight forward since values for IBIs according to PMA are generated automatically.

Abstract
We study the early development of cortical activations synchrony index (ASI). Cortical activations become increasingly synchronized during the last trimester. Interhemispheric synchrony increases more than intrahemispheric synchrony. Our EEG metric ASI can be directly translated to experimental animal studies. ASI holds promise as an early functional biomarker of brain networks.
Early intermittent cortical activity is thought to play a crucial role in the growth of neuronal network development, and large scale brain networks are known to provide the basis for higher brain functions. Yet, the early development of the large scale synchrony in cortical activations is unknown. Here, we tested the hypothesis that the early intermittent cortical activations seen in the human scalp EEG show a clear developmental course during the last trimester of pregnancy, the period of intensive growth of cortico-cortical connections. We recorded scalp EEG from altogether 22 premature infants at post-menstrual age between 30 and 44 weeks, and the early cortical synchrony was quantified using recently introduced activation synchrony index (ASI). The developmental correlations of ASI were computed for individual EEG signals as well as anatomically and mathematically defined spatial subgroups. We report two main findings. First, we observed a robust and statistically significant increase in ASI in all cortical areas. Second, there were significant spatial gradients in the synchrony in fronto-occipital and left-to-right directions. These findings provide evidence that early cortical activity is increasingly synchronized across the neocortex. The ASI-based metrics introduced in our work allow direct translational comparison to in vivo animal models, as well as hold promise for implementation as a functional developmental biomarker in future research on human neonates.

Abstract
We report on two novel patients with ALG11-CDG. The phenotype was characterized by severe psychomotor disability, progressive microcephaly, sensorineural hearing loss, therapy-resistant epilepsy with burst suppression EEG, cerebral atrophy with, in one of them, neuronal heterotopia, and early lethality. Analysis of ALG11 revealed compound heterozygosity involving three novel mutations: the splice site mutation c.45-2A > T, the c.36dupG duplication, and the missense mutation c.479G > T (p.G160V) that was present in both.
