Abstract
We took a multilevel developmental contextual approach and characterized trajectories of alcohol misuse from adolescence through early midlife, examined genetic and environmental contributions to individual differences in those trajectories, and identified adolescent and young adult factors associated with change in alcohol misuse. Data were from two longitudinal population-based studies. FinnTwin16 is a study of Finnish twins assessed at 16, 17, 18, 25, and 35 years (N = 5659; 52% female; 32% monozygotic). The National Longitudinal Study of Adolescent to Adult Health (Add Health) is a study of adolescents from the United States, who were assessed at five time points from 1994 to 2018 (N = 18026; 50% female; 64% White, 21% Black, 4% Native American, 7% Asian, 9% Other race/ethnicity). Alcohol misuse was measured as frequency of intoxication in FinnTwin16 and frequency of binge drinking in Add Health. In both samples, trajectories of alcohol misuse were best described by a quadratic growth curve: Alcohol misuse increased across adolescence, peaked in young adulthood, and declined into early midlife. Individual differences in these trajectories were primarily explained by environmental factors. Several adolescent and young adult correlates were related to the course of alcohol misuse, including other substance use, physical and mental health, and parenthood.

Enhancing the Focus: How Does Parental Incarceration Fit into the Overall Picture of Adverse Childhood Experiences (ACEs) and Positive Childhood Experiences (PCEs)? Res Child Adolesc Psychopathol 2023; 51:1933-1944.

Abstract
Despite the five million children in the U.S. with an incarcerated parent, there is limited research on risk and protective factors for this population. We analyzed data from the National Survey for Children's Health (2018) to: (1) examine associations among parental incarceration and other adverse childhood experiences (ACEs), (2) characterize the association between parental incarceration and youth mental health outcomes, (3) examine differences in positive childhood experiences (PCEs; collective socialization, community engagement, neighborhood amenities, and family problem solving) by parental incarceration status, (4) examine whether PCEs were protective against mental health problems and if there was an interaction with parental incarceration status, and (5) examine the interaction between PCEs, parental incarceration, and ACEs on mental health problems. Results revealed that children with incarcerated parents had higher odds of experiencing other ACEs, higher odds of having mental health problems, and experienced fewer PCEs compared to children without incarcerated parents. Further, although PCEs were associated with a lower odds of mental health problems for both children with and without incarcerated parents, they did not mitigate the negative impact of parental incarceration on mental health outcomes. While PCEs attenuated the association between ACEs and mental health, parental incarceration status did not significantly moderate the interaction. These results highlight vulnerabilities and potential protective factors for children with incarcerated parents and have important implications for the development of multilevel intervention strategies that seek to promote resilience and reduce risk for this population.

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067. Nature 2023; 623:932-937.

Abstract
Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formation and evolution remain poorly understood3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

Abstract
We examined the associations between the developmental timing of interpersonal trauma exposure (IPT) and three indicators of involvement in and quality of romantic relationships in emerging adulthood: relationship status, relationship satisfaction, and partner alcohol use. We further examined whether these associations varied in a sex-specific manner. In a sample of emerging adult college students (N = 12,358; 61.5% female) assessed longitudinally across the college years, we found precollege IPT increased the likelihood of being in a relationship, while college-onset IPT decreased the likelihood. Precollege and college-onset IPT predicted lower relationship satisfaction, and college-onset IPT predicted higher partner alcohol use. There was no evidence that associations between IPT and relationship characteristics varied in a sex-specific manner. Findings indicate that IPT exposure, and the developmental timing of IPT, may affect college students' relationship status. Findings also suggest that IPT affects their ability to form satisfying relationships with prosocial partners.

Abstract
Objectifs: Evaluer rétrospectivement le taux de salariés, confinés (en télétravail) et non confinés, infectés par le SARS-CoV-2 après le 1er confinement (Avril à Mai 2020). Méthode: Un dépistage sérologique des anticorps anti-SARS-CoV-2, IgG et IgM, et un questionnaire sur leurs symptômes a été proposé aux 2090 salariés d’une même entreprise. Résultats: La sérologie était positive pour 5,6% des 786 salariés inclus entre fin avril et juillet 2020 : 4,05% chez les non confinés, et 6,72%, chez les confinés (p=NS). Parmi les positifs, 86,4% avaient présenté des symptômes, sans différence significative entre confinés et non confinés. Enfin, 1.7% des asymptomatiques étaient positifs. Les symptômes n’étaient pas significativement différents entre les 2 groupes sauf pour l’anosmie-agueusie significativement plus fréquente dans le groupe des confinés. Les symptômes significativement associés à une sérologie positive étaient l’anosmie-agueusie, la fièvre-sensation de fièvre-frissons, les courbatures, la fatigue malaise, un syndrome grippal et des symptômes respiratoires. Ce faible taux de contamination peut être le résultat des mesures de prévention renforcées mises en place pour les salariés dès fin janvier 2020 par le Médecin du Travail pour limiter le risque de contamination au sein des locaux. Conclusion: La prévalence du SARS-CoV-2 dans l’entreprise de fin avril à juillet 2020 était inférieure de moitié au taux rapporté dans la population d’Ile de France à la même période sans différence entre les salariés ayant poursuivi leur activité en présentiel par rapport aux confinés.

Abstract
Background Scotland first demonstrated that adherence to nationally agreed hip fracture standards improve patient survival, reduces the duration of admission, and reduces the need for high dependency care. Our study aims to assess adherence to the Irish Hip Fracture Standards (IHFS) in our hospital for 2021 amidst the COVID-19 pandemic, translating to improved clinical outcomes for our patients. Methods The IHF database was retrospectively analysed, comparing quarters 1-4 in 2021 with our 2020 results. Results IHFS1, patient time to the ward < 4hours, was maintained at 67% in 2021 versus 71% overall in 2020. There was improvement in IHFS2, time to surgery within 48 hours, up to 73% in 2021 versus 66% in 2020. IHFS3 was 4% in 2021 versus 3% overall in 2020. Further improvements were noted for IHFS4, with 95% of patients reviewed by a Geriatrician in 2021 versus 87% in 2020. IHFS5 also improved with 97% of patients receiving a bone health assessment in 2021 versus 87% in 2020. Moreover, IHFS6, improved with 97% of patients undergoing a specialised falls assessment in 2021 versus 87% in 2020. Conclusion The improvement in 2021 figures is reflective of the return of redeployed services during the COVID-19 pandemic inclusive of the Orthogeriatric Service, the Fracture Liaison Service Advanced Nurse Practitioner, the Trauma Co-ordinator, and the specialist Orthopaedic ward complete with its Orthopaedic nurses and Multi-Disciplinary Team, and improved Emergency Department pathways. These continued improvements in the IHFS further emphasise that success is dependent on a team that is joined at the hip

Abstract
Background
Nationally agreed hip fracture standards have contributed to the improvement of outcomes in hip fracture patients. In 2020, our hospital was awarded “The Golden Hip” for achieving highest compliance with Irish Hip Fracture Standards (IHFS) nationally for 2019.
Methods
Data from the Irish Hip Fracture Database (IHFD)was retrospectively analysed to assess our performance in 2020 versus 2019 in hip fracture patients over sixty. Multiple quality improvement interventions were put in place throughout 2019 to ensure improvement in IHFS1-6 compliance: Creation of the Hip Fracture Pathway Subgroup, IHFS 1 Breaches Audit, Orthogeriatric input at Orthopaedic inductions, weekly Multi-disciplinary Team meetings, a Nutritional Hip Fracture Pathway and addition of the Fracture Liaison Service Advanced Nurse Practitioner.
Results
There were 239 hip fracture patients in 2020 vs 249 in 2019. IHFS1 compliance improved with the percentage of patients admitted to the Orthopaedic ward within 4 hours increasing to 71% in 2020 from 56% in 2019. There was improvement in IHFS2-time to surgery <48 hours- 66% in 2020 vs 60% in 2019. IHFS3-pressure ulcer rate-was at the national average, 3% in 2020 vs 2% in 2019. IHFS4 (reviewed by a Geriatrician), IHFS5 (received a bone health assessment) and IHFS6 (received a specialised falls assessment) were lower overall; 87% in 2020 vs 98% in 2019. For all quarters (Q),43% of patients met all IHFS in our hospital in 2020 vs 32% in 2019, resulting in €90,000 in Best Practice Tariff funding.
Conclusion
Lower results for IHFS 4,5 and 6 reflect the arrival of the COVID-19 pandemic which led to redeployment of the Orthogeriatric Service and redeployment of the MDT from end of Q1 to Q3. When services in 2020 were preserved,1 in 2 hip fracture patients met all IHFS, vs 1 in 3 patients in 2019. Despite the pandemic, we continued to achieve the highest level of IHFS compliance nationally, being awarded a second consecutive “Golden Hip” for 2020.

Abstract
The field of planetary system formation relies extensively on our understanding of the aerodynamic interaction between gas and dust in protoplanetary disks. Of particular importance are the mechanisms triggering fluid instabilities and clumping of dust particles into aggregates, and their subsequent inclusion into planetesimals. We introduce the timed Epstein multi-pressure vessel at low accelerations, which is an experimental apparatus for the study of particle dynamics and rarefied gas under micro-gravity conditions. This facility contains three experiments dedicated to studying aerodynamic processes: (i) the development of pressure gradients due to collective particle-gas interaction, (ii) the drag coefficients of dust aggregates with variable particle-gas velocity, and (iii) the effect of dust on the profile of a shear flow and resultant onset of turbulence. The approach is innovative with respect to previous experiments because we access an untouched parameter space in terms of dust particle packing fraction, and Knudsen, Stokes, and Reynolds numbers. The mechanisms investigated are also relevant for our understanding of the emission of dust from active surfaces, such as cometary nuclei, and new experimental data will help interpreting previous datasets (Rosetta) and prepare future spacecraft observations (Comet Interceptor). We report on the performance of the experiments, which has been tested over the course of multiple flight campaigns. The project is now ready to benefit from additional flight campaigns, to cover a wide parameter space. The outcome will be a comprehensive framework to test models and numerical recipes for studying collective dust particle aerodynamics under space-like conditions.

The CHALLENGE trial: the effects of a virtual reality-assisted exposure therapy for persistent auditory hallucinations versus supportive counselling in people with psychosis: study protocol for a randomised clinical trial. Trials 2022; 23:773.

Abstract
Background Many patients suffering from schizophrenia spectrum disorders continue having distressing auditory hallucinations in spite of treatment with antipsychotic medication. The aim of this trial is to examine the effect of a targeted virtual reality therapy for persistent auditory hallucinations in individuals with psychosis. The trial explores whether this type of therapy can decrease the severity, frequency and distress of auditory hallucinations and, additionally, whether it can reduce clinical symptoms and enhance daily functioning in individuals with psychosis. Methods The study is a randomised, assessor-blinded parallel-group superiority clinical trial, allocating a total of 266 patients to either the experimental intervention or supportive counselling. The participants will be randomised to either (1) seven sessions of virtual reality therapy or (2) seven sessions of supportive counselling to be delivered within the first 12 weeks after inclusion in the study. All participants will be assessed at baseline and 12 and 24 weeks post-baseline. Independent assessors blinded to the treatment allocation will evaluate the outcome. The primary outcome is the level of auditory hallucinations measured with the Psychotic Symptoms Rating Scales (PSYRATS-AH) total score at the cessation of treatment at 12 weeks. Secondary outcomes are frequency of auditory hallucinations, the distress caused by auditory hallucinations, perceived voice power, patient acceptance of voices, patients’ ability to respond to voices in an assertive way and social and daily function. Discussion Promising evidence of the efficacy of this immersive virtual reality-based therapy for auditory hallucinations exist, but evidence needs to be established in a large, methodological rigorous trial. If the therapy proves to be beneficial in reducing the severity of refractory auditory hallucinations, a large group of patients with schizophrenia and related disorders could be the target group of this short-term psychotherapeutic intervention.

Coffee and energy drink use patterns in college freshmen: associations with adverse health behaviors and risk factors. BMC Public Health 2022; 22:594.

Abstract
Background Public health concern over college students mixing caffeine-containing energy drinks (EDs) and alcohol has contributed to an array of ED-focused research studies. One review found consistent associations between ED use and heavy/problem drinking as well as other drug use and risky behaviors (Nutr Rev 72:87–97, 2014). The extent to which similar patterns exist for other sources of caffeine is not known. The present study examined associations between coffee and ED consumption and alcohol, tobacco and other drug use; alcohol use problems; and parental substance abuse and mental health problems in a sample of college freshmen. Methods Subjects were N = 1986 freshmen at an urban university who completed an on-line survey about demographics; caffeine; alcohol, tobacco and other drug use; and family history. The sample was 61% female and 53% White. Chi-square analyses and multivariable binary or ordinal logistic regression were used to compare substance use, problem alcohol behavior, and familial risk measures across 3 caffeine use groups: ED (with or without Coffee) (ED + Co; N = 350); Coffee but no ED (Co; N = 761); and neither coffee nor ED (NoCE; N = 875) use. Results After adjusting for gender and race, the 3 caffeine use groups differed on 8 of 9 symptoms for alcohol dependence. In all cases, the ED + Co group was most likely to endorse the symptom, followed by the Co group and finally the NoCE group (all p < .002). A similar pattern was found for: use 6+ times of 5 other classes of drugs (all p < .05); extent of personal and peer smoking (all p < .001); and paternal problems with alcohol, drugs and anxiety/depression as well as maternal alcohol problems and depression/anxiety (p < .04). Conclusions The response pattern was ubiquitous, with ED + Co most likely, Co intermediate, and NoCE least likely to endorse a broad range of substance use, problem alcohol behaviors, and familial risk factors. The finding that the Co group differed from both the ED + Co and NoCE groups on 8 measures and from the NoCE group on one additional measure underscores the importance of looking at coffee in addition to EDs when considering associations between caffeine and other risky behaviors.

Low genetic confirmation rate in South Indian subjects with a clinical diagnosis of maturity-onset diabetes of the young (MODY) who underwent targeted next-generation sequencing for 13 genes. J Endocrinol Invest 2022; 45:607-615.

Abstract
PURPOSE To screen for maturity-onset diabetes of the young (MODY) variants in subjects with an early age of onset and positive family history of diabetes mellitus. METHODS 60 subjects with onset of diabetes between 3 and 30 years of age and parental history (onset < 35 years) of diabetes were recruited after excluding autoimmune, pancreatic and syndromic forms of diabetes. Detailed pedigree chart and clinical data were recorded. MODY genetic testing (MODY 1-13) was performed and variant classification was done adhering to the ACMG guidelines. RESULTS Baseline characteristics of subjects were as follows: mean age of onset of diabetes 19.9 ± 7 years, mean duration of diabetes 6.3 ± 6.8 years, BMI 23.3 ± 3 kg/m2 and C-peptide 1.56 ± 1.06 nmol/l. Four out of sixty (6.6%) were positive for variants classifiable as pathogenic/likely pathogenic: one patient with HNF4Ac.691C > T, (p.Arg231Trp), two with HNF 1A c.746C > A(p.Ser249Ter) and c.1340C > T(p.Pro447Leu), and one with ABCC8 c.4544C > T (p.Thr1515Met). MODY 1 and MODY 3 variants were documented in the paediatric age group (< 18 years). CONCLUSION A genetic diagnosis of MODY could be confirmed in only 6.6% (4/60) of patients clinically classifiable as MODY. This is less than that reported in clinically diagnosed MODY subjects of European descent. Newly published population data and more stringent criteria for assessment of pathogenicity and younger age of onset of type 2 diabetes in Indians could have contributed to the lower genetic confirmation rate. Apart from variants in the classical genes (HNF1A, HNF4A), a likely pathogenic variant in a non-classical gene (ABCC8) was noted in this study.

Abstract
BACKGROUND AND AIMS College students report high levels of alcohol use, which can be exacerbated by interpersonal trauma exposure (IPT). Romantic relationships may represent salient contexts for moderating associations between IPT and alcohol use. We examined whether relationship status, partner alcohol use and relationship satisfaction moderated associations between IPT and alcohol use, and whether these associations varied in a sex-specific manner. DESIGN University-wide longitudinal survey of college students. SETTING Large, urban public university in mid-Atlantic United States. PARTICIPANTS We used two subsets of participants (n = 5673 and 3195) from the Spit for Science project, a longitudinal study of college students. Participants completed baseline assessments during the autumn of their freshman year and were invited to complete follow-up assessments every spring thereafter. Participants were included in the present study if they completed surveys at baseline and at least one follow-up assessment (meanfollow-ups = 1.70, range = 1-4). MEASUREMENTS Predictors included precollege and college-onset IPT, relationship status, partner alcohol use, relationship satisfaction and sex. Alcohol consumption was the primary outcome of interest. Pre-college IPT was measured at baseline and all other measures were assessed at each follow-up. FINDINGS Individuals with pre-college IPT consumed more alcohol than those without IPT, but this was mitigated for those in relationships (β = -0.15, P = 0.046, 95% confidence interval (CI) = -0.29, 0.00). Individuals with college-onset IPT consumed more alcohol than those without IPT, and this was more pronounced for those with higher partner alcohol use (β = -0.18, P = 0.001, 95% CI = -0.29, -0.07). Relationship satisfaction was not a significant moderator of the associations between IPT and alcohol use (Ps > 0.05 and 95% CIs include 0). CONCLUSIONS Involvement in relationships, but not relationship satisfaction, appears to reduce the effects of interpersonal trauma exposure (IPT) on alcohol use among US college students, while high partner alcohol use appears to exacerbate it. The moderating effects of relationship characteristics depend on the developmental timing of IPT.

Do proximal hip geometry, trabecular microarchitecture, and prevalent vertebral fractures differ in postmenopausal women with type 2 diabetes mellitus? A cross-sectional study from a teaching hospital in southern India. Osteoporos Int 2021; 32:1585-1593.

Abstract
UNLABELLED This study from southern India showed that the trabecular microarchitecture and proximal hip geometry were significantly impaired in postmenopausal women with diabetes as compared to age and BMI matched non-diabetic controls. This is despite there being no significant difference in bone mineral density at the femoral neck and hip not between both groups. One-third of the study subjects with type 2 diabetes had prevalent vertebral fractures. Bone mineral density assessment as a standalone tool may not adequately reflect bone health in subjects with diabetes. INTRODUCTION There is limited information with regard to bone health in Indian postmenopausal women with type 2 diabetes. We studied the bone mineral density (BMD), trabecular bone score (TBS), prevalent vertebral fractures (VF), proximal hip geometry, and bone mineral biochemistry in ambulatory postmenopausal women with and without type 2 diabetes mellitus (T2DM). METHODS This was a cross-sectional study conducted at a tertiary care center. BMD, TBS, prevalent vertebral fractures, and hip structural analysis (HSA) were assessed using a dual-energy X-ray absorptiometry (DXA) scanner. Bone mineral biochemical profiles were also studied. RESULTS A total of 202 ambulatory postmenopausal women known to have type 2 diabetes mellitus with mean (SD) age of 65.6 (5.2) years and 200 age and BMI matched non-diabetic controls with mean (SD) age of 64.9 (4.7) years were recruited from the local community. Although the prevalence of lumbar spine osteoporosis was significantly lower among cases (30.7%) as compared to controls (42.9%), the prevalence of degraded bone microarchitecture (TBS < 1.200) was significantly higher among cases (51%) than in controls (23.5%); P < 0.001. Prevalent vertebral fractures were not significantly different in cases and controls. The various geometric indices of the proximal hip were significantly impaired in subjects with diabetes as compared to controls. CONCLUSION This study may highlight the utility of the trabecular bone score and hip structural analysis in subjects with diabetes, where the bone mineral density tends to be paradoxically high, and may not adequately predict fracture risk.

A comprehensive investigation of the Galilean moon, Io, by tracing mass and energy flows. EXPERIMENTAL ASTRONOMY 2021; 54:791-807. [PMID: 36915621 PMCID: PMC9998583 DOI: 10.1007/s10686-021-09768-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 05/31/2021] [Indexed: 06/18/2023]
Abstract
Io is the most volcanically-active object in the solar system. The moon ejects a tonne per second of sulphur-rich gases that fill the vast magnetosphere of Jupiter and drives million-amp electrical currents that excite strong auroral emissions. We present the case for including a detailed study of Io within Voyage 2050 either as a standalone mission or as a contribution to a NASA New Frontiers mission, possibly within a Solar System theme centred around current evolutionary or dynamical processes. A comprehensive investigation will provide answers to many outstanding questions and will simultaneously provide information on processes that have formed the landscapes of several other objects in the past. A mission investigating Io will also study processes that have shaped the Earth, Moon, terrestrial planets, outer planet moons, and potentially extrasolar planets. The aim would be simple - tracing the mass and energy flows in the Io-Jupiter system.

Abstract
Introduction Pi and colleagues reviewed eight case-control studies comparing the oral health (decayed, missing and filled teeth [DMFT], Plaque Index [PI], Gingival Index [GI] and salivary pH) of children with autism (n = 475) to children without autism (n = 565).Method The search strategy involved the use of PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang and Chinese Scientific and Technological Journal (VIP) to find case-control studies which met pre-defined inclusion criteria and were published before September 2018. The quality of each study was evaluated using the Newcastle-Ottowa Scale and only high-quality studies were included. Means and standard deviations for outcomes measured by each included study were presented. Data were pooled using the random-effects model via Review Manager 5.3, and presented as mean differences and 95% confidence intervals. Consistency was measured using I2. Sensitivity analysis was performed by removing one study with a large sample to explore effects on heterogeneity.Results The authors found eight eligible case-control studies conducted in Asia (n = 7) or South America (n = 1). Six of the eight compared DMFT of children with autism to those without and three of the eight compared PI, GI and/or salivary pH. While a meta-analysis is presented for each of the oral health outcome areas, there are discrepancies in the reporting. The included studies in each of the meta-analysis do not correspond with the characteristics of the studies provided.Conclusions The authors suggest from their meta-analyses that children with autism experience a higher prevalence of dental disease than children without autism. However, as currently presented, the study lacks internal validity and findings are not reliable.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy and utility of bedside ultrasound (US) by neonatology residents to confirm position of umbilical venous catheter (UVC), umbilical arterial catheter (UAC), and peripherally inserted central catheter (PICC). METHODS In this prospective study, we included neonates who required UVC, UAC or PICC insertion. Two neonatology residents performed all bedside US examinations after a short period of training. Plain radiograph was taken as gold standard. Time taken for confirmation of catheter position by US and radiograph was recorded. RESULTS We recruited 71 neonates for UVC and UAC, and 40 neonates for PICC. Sensitivity and specificity of US in identifying a malpositioned catheter was good for UVC (94% and 66.7% respectively) and UAC (86.7% and 94.5%). Agreement between radiograph and US was good for UVC [0.718 (0.512, 0.861); p < 0.001] and UAC [0.857 (0.682, 0.953); p < 0.001]. Sensitivity (47.8%) of US in identifying a malpositioned PICC was low, though specificity (82.4%) was good. Agreement between radiograph and US in identifying PICC position was poor [0.25 (-0.084, 0.545); p 0.024]. This was due to incorrect interpretation of catheter position on radiograph in some infants, which was confirmed by the radiologist. The median time taken for US was significantly less than time taken for radiograph in confirming the position of UVC (50 vs. 155 minutes; p < 0.001)), UAC (45 vs. 128 minutes; p < 0.001), and PICC (60 vs. 136 minutes; p < 0.001). CONCLUSION US examination byneonatology residents has good diagnostic accuracy in confirming the position of UAC and UVC, and possibly PICC in neonates. The time taken to confirm catheter position by US is significantly less than radiograph.

Abstract
Predicting the structure of multi-protein complexes is a grand challenge in biochemistry, with major implications for basic science and drug discovery. Computational structure prediction methods generally leverage predefined structural features to distinguish accurate structural models from less accurate ones. This raises the question of whether it is possible to learn characteristics of accurate models directly from atomic coordinates of protein complexes, with no prior assumptions. Here we introduce a machine learning method that learns directly from the 3D positions of all atoms to identify accurate models of protein complexes, without using any precomputed physics-inspired or statistical terms. Our neural network architecture combines multiple ingredients that together enable end-to-end learning from molecular structures containing tens of thousands of atoms: a point-based representation of atoms, equivariance with respect to rotation and translation, local convolutions, and hierarchical subsampling operations. When used in combination with previously developed scoring functions, our network substantially improves the identification of accurate structural models among a large set of possible models. Our network can also be used to predict the accuracy of a given structural model in absolute terms. The architecture we present is readily applicable to other tasks involving learning on 3D structures of large atomic systems.

Abstract
PURPOSE Loneliness is a challenge for individuals with psychosis; however, interventions rarely target loneliness in this group. METHOD We developed a pilot positive psychology group intervention designed to reduce loneliness in psychosis and examined its feasibility and acceptability. RESULTS Sixteen participants attended 5.38 (SD = 0.70) out of six sessions, with a dropout rate of 10%. Participants were significantly less lonely at post-treatment (p < 0.001, d = 1.51), and maintained their improvements from post-treatment to follow-up (p = 0.81, d = 0.07). CONCLUSIONS Loneliness may be a feasible and acceptable treatment target within psychosocial treatments.

Abstract
OBJECTIVE Protocol for clozapine rechallenge in patients with a history of clozapine-induced myocarditis. METHOD Clozapine-related cardiovascular adverse effects including myocarditis and cardiomyopathy have limited its widespread use in treatment-resistant schizophrenia. Here, we present a case of clozapine-induced myocarditis and successful cautious rechallenge. Ms. AA, a young female patient with severe psychosis developed myocarditis during her initial clozapine titration phase, which was thus discontinued. Subsequent response to other medications was poor, and she remained significantly disabled. We reviewed blood-based biomarkers identified during the emergence of her index episode of myocarditis and developed a successful clozapine rechallenge protocol, based on careful monitoring of changes in these indices and a very slow clozapine re-titration. RESULTS AND CONCLUSIONS This protocol may have utility in the management of patients with a history of clozapine-induced myocarditis.

Abstract
Chronic heavy metal exposure and the health hazards that ensue are important public-health problems. We highlight the occurrence of hypophosphataemic osteomalacia due to chronic cadmium exposure in the silver industry in India. Three silversmiths presented similarly with clinical, biochemical and radiological evidence of hypophosphataemic osteomalacia. Considering their occupation, their blood samples were screened for heavy metals and were found to have toxic levels of cadmium. They were initiated on neutral phosphate and calcitriol. On follow-up, they reported significant reduction in severity of symptoms. It is essential to maintain a high index of suspicion in diagnosing this condition. A thorough knowledge of the occupational background of patients, as well as ambient conditions at the workplace is of utmost importance in contemplating the possibility of such rare occurrences. Moreover, regulatory agencies and policy makers ought to survey the silver industry and ensure that the metals used are within permissible safe limits of exposure.

Abstract
Women with schizophrenia are often noted to suffer with comorbid depression. Many studies have shown associations between fluctuating oestrogen levels in the brain and mental illness. This study investigates the effect of oestradiol treatment on comorbid depressive symptoms in women with schizophrenia. This study is an 8-week, three-arm, double-blind, randomised-controlled trial. The 180 female participants were aged between 18 and 45, with schizophrenia and ongoing symptoms of psychosis Positive and Negative Syndrome Scale (PANSS) score > 60 despite a stable dose of antipsychotic medication. Depressive symptoms were assessed using Montgomery Asberg Depression Scale (MADRS) with a mean score of 73.77 at baseline. Participants received transdermal oestradiol 200 μg or transdermal oestradiol 100 μg or an identical placebo patch. The a priori outcome measure was the change in PANSS score measured at baseline and days 7, 14, 28 and 56, but in this study, we focused on the change in MADRS score at the same time points. Data were analysed by using Quade's rank analysis of covariance (ANCOVA) (Huitema 1980) with baseline MADRS score as a covariate. We found a fluctuating but overall trend towards improvement of comorbid depressive symptoms in women with schizophrenia taking transdermal oestrogen 200 mcg compared with oestrogen 100 mcg or placebo. The stronger 'antidepressant' effect of 200 mcg transdermal oestradiol was found at day 28 (p = 0.03). Our study suggests that adjunctive oestradiol treatment for depression may be a promising treatment for women with comorbid depression and schizophrenia.

Abstract
Background Early identification of people with CKD in primary care, particularly those with risk factors such as diabetes and hypertension, enables proactive management and referral to specialist services for progressive disease. The 2019 NHS Long Term Plan endorses the development of digitally-enabled services to replace the ‘unsustainable’ growth of the traditional out-patient model of care.Shared views of the complete health data available in the primary care electronic health record (EHR) can bridge the divide between primary and secondary care, and offers a practical solution to widen timely access to specialist advice. Methods We describe an innovative community kidney service based in the renal department at Barts Health NHS Trust and four local clinical commissioning groups (CCGs) in east London. An impact evaluation of the changes in service delivery used quantitative data from the virtual CKD clinic and from the primary care electronic health records (EHR) of 166 participating practices. Survey and interview data from health professionals were used to explore changes to working practices. Results Prior to the start of the service the general nephrology referral rate was 0.8/1000 GP registered population, this rose to 2.5/1000 registered patients by the second year of the service. The majority (> 80%) did not require a traditional outpatient appointment, but could be managed with written advice for the referring clinician. The wait for specialist advice fell from 64 to 6 days. General practitioners (GPs) had positive views of the service, valuing the rapid response to clinical questions and improved access for patients unable to travel to clinic. They also reported improved confidence in managing CKD, and high levels of patient satisfaction. Nephrologists valued seeing the entire primary care record but reported concerns about the volume of referrals and changes to working practices. Conclusions ‘Virtual’ specialist services using shared access to the complete primary care EHR are feasible and can expand capacity to deliver timely advice. To use both specialist and generalist expertise efficiently these services require support from community interventions which engage primary care clinicians in a data driven programme of service improvement.

Abstract
ObjectivesEcchordosis physaliphora (EP) is a benign, usually asymptomatic, notochord tumour but may also present with a spontaneous CSF fistula. Differentiating EP from its more aggressive counterpart, chordoma is challenging but important as the clinical course and management differ significantly, with the latter requiring proton beam radiotherapy. This case series aims to further inform this discussion.DesignCase series.SubjectsPatients with suspected EP from 2015–2018.MethodsRetrospective analysis.ResultsSix patients were identified. Four presented with suspected CSF leak. MRI revealed a T1-hypointense and T2-hyperintense clival lesion without enhancement. CT showed pneumocephalus, a clival defect and no mass lesion. All underwent endoscopic endonasal repair of CSF fistula with biopsy. Histology revealed physaliphorous cells with no mitoses; immunohistochemistry confirmed notochord origin (EMA, S100, CD10 and/or MNF116) and low proliferation index. In 2 patients, EP was found incidentally on imaging and these lesions have remained static on follow-up.ConclusionsIn the absence of a clival mass, notochord remnant lesions with benign histopathology can be treated as EP and patients can avoid radiotherapy. The diagnosis of EP, however, remains challenging as no distinctive histopathological marker exists to differentiate it from chordoma and until a genetic or immunohistochemical marker is identified, the diagnosis rests solely on the presence or absence of a mass on imaging.

Abstract
Cognitive impairments cause significant functional issues for people with schizophrenia, often emerging before the onset of hallucinations, delusions and other psychosis symptoms. Current pharmacological treatments do not target cognitive dysfunction. Several lines of evidence support the beneficial effects of estrogens on cognition. Raloxifene hydrochloride, a selective estrogen receptor modulator, has been associated with cognitive improvements in healthy postmenopausal women and in schizophrenia, although findings are inconsistent. Using pooled data from two clinical trials, the aim of the current study was to compare the efficacy of 120 mg/day adjunctive raloxifene to placebo for 12 weeks on cognitive performance in women with schizophrenia who were stratified by menopause status (pre-menopausal; peri-menopausal or post-menopausal). A total of sixty-nine participants with a diagnosis of schizophrenia or schizoaffective disorder were included. Cognition was assessed at baseline and study end using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Results indicated that after stratifying for menopause status (strata) and adjusting for endogenous hormone levels (estrogen, progesterone, follicle stimulating hormone and luteinising hormone), semantic fluency, picture naming and list recognition change from baseline scores for the raloxifene group differed significantly from the placebo group. The findings from the current study highlight the importance of considering menopause status when interpreting the effects of hormonal treatments.

Abstract
Liability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest genome-wide association study to date of DSM-IV-diagnosed AD. Genome-wide data on 14,904 individuals with AD and 37,944 controls from 28 case-control and family-based studies were meta-analyzed, stratified by genetic ancestry (European, n = 46,568; African, n = 6,280). Independent, genome-wide significant effects of different ADH1B variants were identified in European (rs1229984; P = 9.8 × 10-13) and African ancestries (rs2066702; P = 2.2 × 10-9). Significant genetic correlations were observed with 17 phenotypes, including schizophrenia, attention deficit-hyperactivity disorder, depression, and use of cigarettes and cannabis. The genetic underpinnings of AD only partially overlap with those for alcohol consumption, underscoring the genetic distinction between pathological and nonpathological drinking behaviors.

Abstract
Cognitive impairments are a core feature of schizophrenia and contribute significantly to functional complications. Current pharmacological treatments do not ameliorate cognitive dysfunction and the aetiology of cognitive impairments are poorly understood. Hormones of the hypothalamic-pituitary-gonadal (HPG) axis that regulate reproductive function have multiple effects on the development, maintenance and function of the brain and have been suggested to also influence cognition. The aim of the current study was to investigate how HPG axis hormones effect cognition, specifically exploring the influence of menopause status and menstrual cycle irregularity on cognitive performance in women with schizophrenia. The data for the present study represents pooled baseline data from three clinical trials. Two hundred and forty female participants with a diagnosis of schizophrenia or schizoaffective disorder were included in the analysis. Cognition was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status. Hormone assays for serum sex steroids and pituitary hormones (including estradiol, progesterone, luteinising hormone and follicle-stimulating hormone) were conducted and women were classified as postmenopausal; perimenopausal; premenopausal/reproductive, further classified into regular and irregular menstrual cycles. To model a comparison of cognitive performance for i) perimenopausal; ii) post-menopausal women and iii) reproductive aged women with irregular cycles to reproductive aged women with regular cycles a semiparametric regression model (generalised additive mode) was fitted. The results revealed that in females with schizophrenia, menstrual cycle irregularity predicted significantly poorer cognitive performance in the areas of psychomotor speed, verbal fluency and verbal memory. Perimenopause was not associated with cognitive changes and the post-menopausal period was associated with poorer visuospatial performance. This study provides evidence to associate reproductive hormones with cognitive dysfunction in schizophrenia.

Despite the mandatory nature of Lyme disease (LD) reporting in New York State (NYS), it is believed that only a fraction of the LD cases diagnosed annually are reported to public health authorities. Lack of complete LD case reporting generally stems from (i) lack of report of provider-diagnosed cases where supportive laboratory testing is not ordered or results are negative (i.e. provider underreporting) and (ii) incomplete case information (clinical laboratory reporting only with no accompanying clinical information) such that cases are considered 'suspect' and not included in national and statewide case counts (i.e. case misclassification). In an attempt to better understand LD underreporting in NYS, a two-part study was conducted in 2011 using surveillance data from three counties. Case misclassification was assessed by obtaining medical records on suspect cases and reclassifying according to the surveillance case definition. To assess provider underreporting, lists of patients for whom ICD-9-CM code 088.81 (LD) had been used were reported to NYS Department of Health (NYSDOH). These lists were matched to the NYSDOH case reporting system, and medical records were requested on patients not previously reported; cases were then classified according to the case definition. When including both provider underreporting and case misclassification, approximately 20% (range 18.4-24.6%) more LD cases were identified in the three-county study area than were originally reported through standard surveillance. The additional cases represent a minimum percentage of unreported cases; the true percentage of unreported cases is likely higher. Unreported cases were more likely to have a history of erythema migrans (EM) rash and were more likely to be young paediatric cases. Results of the study support the assertion that LD cases are underreported in NYS. Initiatives to increase reporting should highlight the importance of reporting clinically diagnosed EM and be targeted to those providers most likely to diagnose LD, specifically providers treating paediatric patients.

Abstract
Abstract
Background
In 2013 the ASCO/CAP Guidelines for HER2 testing were updated and revised to improve the accuracy of Her2 testing and its utility as a predictive marker in breast cancer. In this prospective cross-sectional study, we assessed the proportion of Her2 positive and equivocal cases in a real-world setting in Germany. Patients' characteristics and tumor biological factors were evaluated. Furthermore, we analyzed the effect of the updated recommendations on the clinical management.
Methods
This IRB approved prospective analysis included patients with primary breast cancer. Patients with primary stage IV and recurrent breast cancer were excluded. Data was collected from 2012-2017 in six certified breast centers using a personal questionnaire and data from the patients' medical records.
Results
2705 primary breast cancer cases were analyzed. The groups consisted of 320(11.8%) TNBC, 1956 (72.31%) luminal breast cancer patients and 381 (14.08%)Her2 positive cancer patients. 18 (1%) patients were classified as equivocal. 30 patients did not meet the criteria of any of these groups. No significant difference was seen in positive lymph node status between all groups. Tumor size at diagnosis was larger for TNBC compared to the other groups. 81,9% of all TNBC, 65.1% of the Her2 type, 44.2% of the luminal type and 44.44% (8/18) of the equivocal cases were grade 3 tumors. 3 cases with unresolved Her2 status were diagnosed in 2013 and 6 cases in 2016. 17/18 equivocal cases were hormone receptor positive, 1/18 was hormone receptor negative. In 12/18 cases adjuvant or neoadjuvant chemotherapy was recommended. Trastuzumab was recommended in 9/18 of the cases. 2/18 patients were BRCA mutation carriers. 2/18 received an oncologic treatment for another cancer prior to their breast cancer diagnosis. 1/18 patient received primary endocrine therapy with an aromatase inhibitor. 6/18 patients had a positive family history for breast cancer.
Conclusions
Our study indicates that the 2013 ASCO/CAP update does not affect the overall Her2 positivity rate in breast cancer. Although the proportion of tests and retests increased, only few unresolved cases remained. Despite the fact that the benefit of anti-Her2 directed therapy in equivocal cases is unproven, oncologists were more likely to recommend Trastuzumab, if chemotherapy was indicated for high risk breast cancer. There are numerous factors that could explain equivocal findings. Interestingly, a significant number of our patients presented endogenous or exogenous risk factors for chromosomal aberrations that might be responsible for unresolved Her2 cases.

Abstract
BACKGROUND Troponin-T is a commonly used cardiac biomarker, which could be useful in perinatal asphyxia. We aimed to analyze troponin-T concentrations in asphyxiated neonates and to correlate the concentrations with clinical outcomes. METHODS Data were collected from electronic medical records of neonates diagnosed with perinatal asphyxia over a period of four years. RESULTS There were 63 neonates with moderate to severe encephalopathy, in whom serial troponin-T concentrations had been done on days 1, 3, and 7. 53 (84%) asphyxiated infants had troponin-T concentration >100 pg/ml at 2-4 h of life.The difference in troponin-T concentrations between moderate and severe encephalopathy was not statistically significant (173 vs. 263 pg/ml, p value 0.40). The difference in the concentrations at 72 hours between cooled and non-cooled neonates was not significant (48.5 vs. 62.5 pg/ml, p value 0.22). Troponin-T concentration was significantly higher in babies with hypotensive shock and hepatic injury, but not acute kidney injury. There was no significant correlation between troponin-T and the extent of resuscitation needed.Troponin-T concentration on day 1 of life was significantly higher in babies who died than who survived (407 vs. 168 pg/ml, p value 0.03). ROC curve for troponin-T to predict mortality had an area under the curve (AUC) of 0.803; the best cut-off value (190 pg/ml) had 82% sensitivity and 80% specificity. CONCLUSION There was no significant difference in troponin-T concentrations between cooled and non-cooled neonates. Troponin-T concentration had a good predictive accuracy for mortality before discharge.

ALDH2*2 and peer drinking in East Asian college students. THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2017; 43:678-685. [PMID: 28471244 PMCID: PMC5916547 DOI: 10.1080/00952990.2017.1314489] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Revised: 03/29/2017] [Accepted: 03/29/2017] [Indexed: 12/21/2022]
Abstract
BACKGROUND The ALDH2*2 allele (A-allele) at rs671 is more commonly carried by Asians and is associated with alcohol-related flushing, a strong adverse reaction to alcohol that is protective against drinking. Social factors, such as having friends who binge drink, also contribute to drinking in Asian youth. OBJECTIVES This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking. METHODS Subjects (N = 318, 63.25% female) were East Asian college students in the United States who reported drinking alcohol. Data were from the freshman year of a university survey that included a saliva DNA sample. ALDH2*2 status was coded ALDH2*2(+) (A/G and A/A genotypes) and ALDH2*2(-) (G/G genotype). Peer drinking was students' perception of how many of their friends "got drunk". RESULTS Main effects of ALDH2*2(-) and having more friends who got drunk were associated with greater alcohol consumption. The ALDH2*2 × peer drunkenness interaction showed a stronger positive association with alcohol consumption for ALDH2*2(-) versus ALDH2*2(+) at increasing levels of peer drunkenness. Follow-up comparisons within each peer drunkenness level identified significantly higher alcohol consumption for ALDH2*2(-) compared to ALDH2*2(+) at the all friends got drunk level. CONCLUSION There was evidence of a stronger effect for ALDH2*2(-) compared to ALDH2*2(+) with greater alcohol use when students were more exposed to peer drinking. Findings contribute to a growing literature on the interrelationships between genetic influences and more permissive environments for alcohol consumption.
