Screening, brief intervention and referral to treatment (SBIRT) by nurses to college students who use electronic cigarettes

Abstract Objective To examine how screening, brief intervention and referral to treatment (SBIRT) influenced nurses’ knowledge, attitude, responsibility and confidence when caring for college students using electronic cigarettes (EC). Participants Nurses (n = 8) in an urban university campus in the US. Methods Training sessions included classroom instruction on SBIRT and EC, and practice with a standardized patient. Surveys administered pre and post training, and at conclusion. Measurement included nurse’s knowledge of SBIRT and EC; and attitude, confidence and responsibility when using SBIRT. Students with past 90-day EC use were administered SBIRT by nurses and referred to health educator on request. Results Over 6 weeks, 103 students reported EC use, 80 received SBIRT and 36 were referred to health educator. Nurses gained knowledge, supported using SBIRT, and reported that skills increased. Conclusions SBIRT is a motivational interviewing skill that nurses can learn to use to engage with college students who use EC.
Early maternal loss leads to short- but not long-term effects on diurnal cortisol slopes in wild chimpanzees

The biological embedding model (BEM) suggests that fitness costs of maternal loss arise when early-life experience embeds long-term alterations to hypothalamic-pituitary-adrenal (HPA) axis activity. Alternatively, the adaptive calibration model (ACM) regards physiological changes during ontogeny as short-term adaptations. Both models have been tested in humans but rarely in wild, long-lived animals. We assessed whether, as in humans, maternal loss had short- and long-term impacts on orphan wild chimpanzee urinary cortisol levels and diurnal urinary cortisol slopes, both indicative of HPA axis functioning. Immature chimpanzees recently orphaned and/or orphaned early in life had diurnal cortisol slopes reflecting heightened activation of the HPA axis. However, these effects appeared short-term, with no consistent differences between orphan and non-orphan cortisol profiles in mature males, suggesting stronger support for the ACM than the BEM in wild chimpanzees. Compensatory mechanisms, such as adoption, may buffer against certain physiological effects of maternal loss in this species.
Nonvolatile programmable silicon photonics using an ultralow-loss Sb2Se3 phase change material

An ultralow-loss optical phase change material enables reversible programming of the flow of light in silicon photonics. The next generation of silicon-based photonic processors and neural and quantum networks need to be adaptable, reconfigurable, and programmable. Phase change technology offers proven nonvolatile electronic programmability; however, the materials used to date have shown prohibitively high optical losses, which are incompatible with integrated photonic platforms. Here, we demonstrate the capability of the previously unexplored material Sb2Se3 for ultralow-loss programmable silicon photonics. The favorable combination of large refractive index contrast and ultralow losses seen in Sb2Se3 facilitates an unprecedented optical phase control exceeding 10π radians in a Mach-Zehnder interferometer. To demonstrate full control over the flow of light, we introduce nanophotonic digital patterning as a previously unexplored conceptual approach with a footprint orders of magnitude smaller than state-of-the-art interferometer meshes. Our approach enables a wealth of possibilities in high-density reconfiguration of optical functionalities on silicon chip.
Hypothermia versus Normothermia after Out-of-Hospital Cardiac Arrest

BACKGROUND: Targeted temperature management is recommended for patients after cardiac arrest, but the supporting evidence is of low certainty. METHODS: In an open-label trial with blinded assessment of outcomes, we randomly assigned 1900 adults with coma who had had an out-of-hospital cardiac arrest of presumed cardiac or unknown cause to undergo targeted hypothermia at 33°C, followed by controlled rewarming, or targeted normothermia with early treatment of fever (body temperature, &#8805;37.8°C). The primary outcome was death from any cause at 6 months. Secondary outcomes included functional outcome at 6 months as assessed with the modified Rankin scale. Prespecified subgroups were defined according to sex, age, initial cardiac rhythm, time to return of spontaneous circulation, and presence or absence of shock on admission. Prespecified adverse events were pneumonia, sepsis, bleeding, arrhythmia resulting in hemodynamic compromise, and skin complications related to the temperature management device. RESULTS: A total of 1850 patients were evaluated for the primary outcome. At 6 months, 465 of 925 patients (50%) in the hypothermia group had died, as compared with 446 of 925 (48%) in the normothermia group (relative risk with hypothermia, 1.04; 95% confidence interval [CI], 0.94 to 1.14; P = 0.37). Of the 1747 patients in whom the functional outcome was assessed, 488 of 881 (55%) in the hypothermia group had moderately severe disability or worse (modified Rankin scale score &#8805;4), as compared with 479 of 866 (55%) in the normothermia group (relative risk with hypothermia, 1.00; 95% CI, 0.92 to 1.09). Outcomes were consistent in the prespecified subgroups. Arrhythmia resulting in hemodynamic compromise was more common in the hypothermia group than in the normothermia group (24% vs. 17%, P<0.001). The incidence of other adverse events did not differ significantly between the two groups. CONCLUSIONS: In patients with coma after out-of-hospital cardiac arrest, targeted hypothermia did not lead to a lower incidence of death by 6 months than targeted normothermia.

Influence of social determinants of health on skin to skin contact between mother and newborn.

OBJECTIVE to analyze the association of skin-to-skin contact and social determinants of health. METHODS this is a cross-sectional study with 187 medical records of newborns from a reference rooming in in northeastern Brazil. An instrument with maternal and neonatal data was used. Analysis was descriptive and inferential statistics. For the associations, a chi-square test was used to measure strength, an Odds Ratio was calculated, with a 95% confidence interval. RESULTS 62% of newborns who made skin-to-skin contact at birth were eutrophic, full-term, Apgar > 7, mothers with prenatal care and without abortion. The determinants associated with non-skin-to-skin contact were preterm (CR=3.2;95%CI: 2.72-18.98); 1st minute Apgar < 7 (CR:2.9;95%CI: 2.38-3.06), cesarean section (CR:8.4;95%CI: 4.29-16.57), and unhealthy NB (CR 12.7;95%CI: 4.9-32.67). We used STROBE guidelines. CONCLUSION skin-to-skin contact was influenced by gestational age, Apgar, delivery, and newborn health.
Oral Amylin Treatment Reduces the Pathological Cascade of Alzheimer’s Disease in a Mouse Model

Intraperitoneal injection of amylin or its analog reduces Alzheimer’s disease (AD) pathology in the brains. However, self-injecting amylin analogs is difficult for patients due to cognitive deficits. This work aims to study the effects of amylin on the brain could be achieved by oral delivery as some study reported that amylin receptor may be present in the gastrointestinal tract. A 6-week course of oral amylin treatment reduced components of AD pathology, including the levels of amyloid-β, phosphorylated tau, and ionized calcium binding adaptor molecule 1. The treatment reduced active forms of cyclin-dependent kinase 5. Oral amylin treatment led to improvements in social deficit in AD mouse. Using immunofluorescence, we observed the amylin receptor complexed with the calcitonin receptor and receptor activity-modifying proteins in the enteric neurons. The study suggests the potential of the oral delivery of amylin analogs for the treatment of AD and other neurodegenerative diseases through enteric neurons.
Effects of l-citrulline supplementation on nitric oxide and antioxidant markers after high-intensity interval exercise in young men: a randomised controlled trial

Abstract l-Citrulline (l-Cit) is a non-essential amino acid that stimulates nitric oxide (NO) production and improves exercise performance by reducing muscle damage indices; however, the direct benefits of l-Cit on antioxidant markers are unclear. The aim of this study was to examine antioxidant responses to high-intensity interval exercise following acute l-Cit supplementation. Nine young men (21 (sd 1) years) participated in a double-blind crossover study in which they received 12 g of l-Cit and placebo (PL) an hour prior to high-intensity interval exercise on two occasions, separated by a 7-d washout period. Blood samples were obtained before (PRE), immediately after (IP), 10 (10P) and 30 min after exercise (30P) from the cubital vein using standard procedures. Serum concentrations of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and NO metabolites (NOx) were measured. The exercise protocol significantly elevated SOD (P = 0·01) and GPx (P = 0·048) from PRE to 10P in the l-Cit group with greater changes than the PL group. CAT concentrations increased IP (P = 0·014) and remained elevated at 10P (P = 0·03) and 30P (P = 0·015) in both the l-Cit and PL conditions. NOx concentrations increased IP (P = 0·05) in the l-Cit group with greater changes than PL group in PRE to IP, PRE to 10P and PRE to 30P (P < 0·05). Our data indicate that l-Cit supplementation (single 12 g dose pre-exercise) induces improvements in antioxidant markers following a session of high-intensity interval exercise in young men.
Nano-to-micro spatiotemporal imaging of magnetic skyrmion’s life cycle

The unique life cycle of the skyrmions was precisely tracked by pump-probe Lorentz transmission electron microscopy. Magnetic skyrmions are self-organized topological spin textures that behave like particles. Because of their fast creation and typically long lifetime, experimental verification of skyrmion’s creation/annihilation processes has been challenging. Here, we successfully track skyrmion dynamics in defect-introduced Co9Zn9Mn2 by using pump-probe Lorentz transmission electron microscope. Following the nanosecond photothermal excitation, we resolve 160-nm skyrmion’s proliferation at <1 ns, contraction at 5 ns, drift from 10 ns to 4 μs, and coalescence at ~5 μs. These motions relay the multiscale arrangement and relaxation of skyrmion clusters in a repeatable cycle of 20 kHz. Such repeatable dynamics of skyrmions, arising from the weakened but still persistent topological protection around defects, enables us to visualize the whole life of the skyrmions and demonstrates the possible high-frequency manipulations of topological charges brought by skyrmions.
Case-control study in ALS using the National ALS Registry: lead and agricultural chemicals are potential risk factors

Abstract Objective: To identify occupational risk factors for ALS using well-characterized participants with ALS (P-ALS), sibling controls (S-controls), and matched population controls (P-controls) within the National ALS Registry. We also compared oxidative stress (OS) biomarkers between groups. Methods: P-ALS were recruited over 4 years. Demographic, socioeconomic, and medical data were ascertained from medical records and structured interviews. P-ALS were followed prospectively for 2 years or until death, whichever came sooner. S-controls and age-, sex-, race/ethnicity-, and residential location-matched P-controls were recruited over 3 years. Occupational exposure to lead and agricultural chemicals (ACs) were assigned by an occupational hygienist, blinded to case status. OS biomarkers in urine were measured. Results: P-ALS (mean age 62.8 years; 63% males) resided across the United States. Demographic and socioeconomic variables did not differ among P-ALS, S-controls, and P-controls. P-ALS were more likely to report occupations with exposure to lead (adjusted OR (aOR)=2.3, 95% CI 1.1, 4.6) and ACs (aOR = 2.4, 95% CI 1.2, 4.6) compared to pooled controls. Among those with occupations with exposure to both lead and ACs, aOR was 7.2 (95% CI 2.0, 26.1). Urinary 8-oxo-dG was significantly elevated among P-ALS (11.07 ± 5.42 ng/mL) compared to S-controls, P-controls, or pooled controls (pooled 7.43 ± 5.42 ng/mL; p < 0.0001) but was not associated with occupational exposure to either lead or ACs. Conclusions: Findings reveal increased risk of ALS diagnosis among those with occupational exposure to lead and ACs and increased OS biomarkers among cases compared to controls. OS may be an important pathogenic mechanism in ALS.
Fingerprint Presentation Attack Detector Using Global-Local Model

The vulnerability of automated fingerprint recognition systems (AFRSs) to presentation attacks (PAs) promotes the vigorous development of PA detection (PAD) technology. However, PAD methods have been limited by information loss and poor generalization ability, resulting in new PA materials and fingerprint sensors. This article thus proposes a global–local model-based PAD (RTK-PAD) method to overcome those limitations to some extent. The proposed method consists of three modules, called: 1) the global module; 2) the local module; and 3) the rethinking module. By adopting the cut-out-based global module, a global spoofness score predicted from nonlocal features of the entire fingerprint images can be achieved. While by using the texture in-painting-based local module, a local spoofness score predicted from fingerprint patches is obtained. The two modules are not independent but connected through our proposed rethinking module by localizing two discriminative patches for the local module based on the global spoofness score. Finally, the fusion spoofness score by averaging the global and local spoofness scores is used for PAD. Our experimental results evaluated on LivDet 2017 show that the proposed RTK-PAD can achieve an average classification error (ACE) of 2.28% and a true detection rate (TDR) of 91.19% when the false detection rate (FDR) equals 1.0%, which significantly outperformed the state-of-the-art methods by ~10% in terms of TDR (91.19% versus 80.74%).
Does interviewer gender influence a mother’s response to household surveys about maternal and child health in traditional settings? A qualitative study in Bihar, India

Background Two probability surveys, conducted in the same districts of Bihar, India (Aurangabad and Gopalganj) at approximately the same time in 2016 using identical questionnaires and similar survey methods, produced significantly different responses for 37.2% (58/156) of the indicator comparisons. Interviewers for one survey were men while for the other they were women. Respondents were mothers of children aged 0–59 months living in a traditional rural setting. We examined the influence of interviewer gender on mothers’ survey responses and their implications for interpreting survey results. Methods We used qualitative methods including 10 focus group discussions (FGDs) and 33 in-depth interviews (IDIs) in the same locations as the 2016 surveys. FGD participants were purposefully selected mothers with children 0–59 months, husbands and other in-law family members. IDIs were carried out with frontline health-workers, enumerators and supervisors from the two previous household surveys. Results Findings revealed a preference for female interviewers for household surveys in study districts as they facilitated access to mothers and reduced their discomfort as survey participants. However, this gender preference was related to the survey question. Regardless of age, caste and educational level, most mothers were not permitted to communicate with men (aside from husbands) about female-specific health topics, including birth preparedness, delivery, menstrual cycles, contraception, breastfeeding, sexual behaviour, sexually transmitted disease, and domestic violence. Mothers in higher castes perceived these social restrictions more acutely than mothers in lower castes. There was no systematic direction of the resulting error. Mothers were willing to discuss child health issues with interviewers of either gender. Conclusions Interviewer gender is an important consideration when designing survey protocols for maternal and reproductive health studies and when selecting and training enumerators. Female interviewers are optimal for traditional settings in Bihar as they are more likely to obtain accurate data on sensitive topics and reduce the potential for non-sampling error due to their reduced social distance with maternal respondents.
Extensive Health Care Utilization and Costs of an Early Liver Transplantation Program for Alcoholic Hepatitis

Early liver transplantation (LT) for severe alcoholic hepatitis (AH) is a rescue therapy for highly selected patients with favorable psychosocial profiles not responding to medical therapy. Given the expected increase of AH candidate referrals requiring complex care and comprehensive evaluations, increased workload and cost might be expected from implementing an early LT program for AH but have not been determined. Some centers may also view AH as a strategy to expeditiously increase LT volume and economic viability. The aim of this study was to determine the health care use and costs of an early LT program for AH. Analyses of prospective databases of AH, interhospital transfers, and the hospital accounting system at a single center were performed from July 2011 to July 2016. For 5 years, 193 patients with severe AH were evaluated at our center: 143 newly referred transfers and 50 direct admissions. Annual increases of 13% led to 2 to 3 AH transfers/month and AH becoming the top reason for transfer. There were 169 (88%) nonresponders who underwent psychosocial evaluations; 15 (9%) underwent early LT. The median cost of early LT was $297,422, which was highly correlated with length of stay (r = 0.83; P < 0.001). Total net revenue of the program from LT admission to 90 days after LT was −$630,305 (−5.0% revenue), which was inversely correlated with MELD score (r = −0.70; P = 0.004) and yielded lower revenue than a contemporaneous LT program for acute‐on‐chronic liver failure (ACLF; $118,168; 1.4% revenue; P = 0.001). The health care use and costs of an early LT program for AH are extensive and lifesaving with marginally negative net revenue. Significantly increasing care of severe AH patients over 5 years resulted in increased LT volume, but at a lower rate than ACLF, and without improving economic outcomes due to high MELD and prolonged length of stay.
m6A demethylase ALKBH5 controls CD4+ T cell pathogenicity and promotes autoimmunity

ALKBH5 maintains CD4+ T cell pathogenicity during autoimmune disease via regulating IFN-γ and CXCL2. N6-methyladenosine (m6A) modification is dynamically regulated by “writer” and “eraser” enzymes. m6A “writers” have been shown to ensure the homeostasis of CD4+ T cells, but the “erasers” functioning in T cells is poorly understood. Here, we reported that m6A eraser AlkB homolog 5 (ALKBH5), but not FTO, maintains the ability of naïve CD4+ T cells to induce adoptive transfer colitis. In addition, T cell–specific ablation of ALKBH5 confers protection against experimental autoimmune encephalomyelitis. During the induced neuroinflammation, ALKBH5 deficiency increased m6A modification on interferon-γ and C-X-C motif chemokine ligand 2 messenger RNA (mRNA), thus decreasing their mRNA stability and protein expression in CD4+ T cells. These modifications resulted in attenuated CD4+ T cell responses and diminished recruitment of neutrophils into the central nervous system. Our findings reveal an unexpected specific role of ALKBH5 as an m6A eraser in controlling the pathogenicity of CD4+ T cells during autoimmunity.
Sex influences on the neurocognitive outcome of preterm children

This article presents a revision of the literature regarding the influence of sex differences on the recovery and long‐term behavioral and cognitive outcomes of preterm children. After initial discussion of some methodological concerns, the literature regarding the concept of “male disadvantage,” which is often used when talking about early neurological and psychomotor outcomes in preterm children, is presented. Subsequently, the literature data on sex‐related differences in preterm children are discussed, focusing on their influence on the developmental pathways of cognition, language, executive function, behavior and affect, and response to rehabilitation therapies. Finally, evidence about brain structural and connectivity correlates of sex differences in the brain of preterm survivors is taken into account. Although visuo‐spatial and visuo‐perceptual functioning is widely studied in the preterm child and is strongly sex specific, little to no data are available regarding male–female differences in preterm children and the interaction effect between sex and preterm birth. For this reason, original data analyses of male–female differences in visuo‐spatial performance from a small sample of preterm children are also presented.
Band Engineering of Dirac Semimetals Using Charge Density Waves

New developments in the field of topological matter are often driven by materials discovery, including novel topological insulators, Dirac semimetals, and Weyl semimetals. In the last few years, large efforts have been made to classify all known inorganic materials with respect to their topology. Unfortunately, a large number of topological materials suffer from non‐ideal band structures. For example, topological bands are frequently convoluted with trivial ones, and band structure features of interest can appear far below the Fermi level. This leaves just a handful of materials that are intensively studied. Finding strategies to design new topological materials is a solution. Here, a new mechanism is introduced, which is based on charge density waves and non‐symmorphic symmetry, to design an idealized Dirac semimetal. It is then shown experimentally that the antiferromagnetic compound GdSb0.46Te1. 48 is a nearly ideal Dirac semimetal based on the proposed mechanism, meaning that most interfering bands at the Fermi level are suppressed. Its highly unusual transport behavior points to a thus far unknown regime, in which Dirac carriers with Fermi energy very close to the node seem to gradually localize in the presence of lattice and magnetic disorder.
A hierarchical, multivariate meta-analysis approach to synthesizing global change experiments.

Meta-analyses enable synthesis of results from globally distributed experiments to draw general conclusions about the impacts of global change factors on ecosystem function. Traditional meta-analyses, however, are challenged by the complexity and diversity of experimental results. We illustrate how several key issues can be addressed via a multivariate, hierarchical Bayesian meta-analysis (MHBM) approach applied to information extracted from published studies. We applied an MHBM to log-response ratios for aboveground biomass (AB, n = 300), belowground biomass (BB, n = 205), and soil CO2 exchange (SCE, n = 544), representing 100 studies. The MHBM accounted for study duration, climate effects, and covariation among the AB, BB, and SCE responses to elevated CO2 (eCO2 ) and/or warming. The MHBM revealed significant among-study covariation in the AB and BB responses to experimental treatments. The MHBM imputed missing duration (4.2%) and climate (6%) data, and revealed that climate context governs how eCO2 and warming impact ecosystem function. Predictions identified biomes that may be particularly sensitive to eCO2 or warming, but that are under-represented in global change experiments. The MHBM approach offers a flexible and powerful tool for synthesizing disparate experimental results reported across multiple studies, sites, and response variables.
