The δ13C Value of Fingerstick Blood Is a Valid, Reliable, and Sensitive Biomarker of Sugar-Sweetened Beverage Intake in Children and Adolescents.

Background Reliance on self-reported dietary intake methods is a commonly cited research limitation, and dietary misreporting is a particular problem in children and adolescents. Objective indicators of dietary intake, such as dietary biomarkers, are needed to overcome this research limitation. The added sugar (AS) biomarker δ13C, which measures the relative abundance of 13C to 12C, has demonstrated preliminary validity in adults. Objective The purpose of this investigation was to determine the comparative validity, test-retest reliability, and sensitivity of the δ13C biomarker to detect AS and sugar-sweetened beverage (SSB) intake using fingerstick blood samples in children and adolescents. Methods Children (aged 6-11 y, n = 126, 56% male, mean ± SD age: 9 ± 2 y) and adolescents (aged 12-18 y, n = 200, 44% male, mean ± SD age: 15 ± 2 y) completed 4 testing sessions within a 3-wk period. Participants' height, weight, demographic characteristics, and health history were determined at the first session; 24-h recalls were obtained at each visit and fingerstick blood samples were collected at visits 1 and 3. Samples were analyzed for δ13C value using natural abundance stable isotope mass spectrometry. δ13C value was compared with dietary outcomes in the full sample, and in child and adolescent subgroups. t Tests and correlational analyses were used to assess biomarker validity and reliability, whereas logistic regression and area under the receiver-operator characteristic curve (AUC) were used to evaluate sensitivity. Results Reported mean ± SD AS consumption was 82.2 ± 35.8 g/d and 329 ± 143 kcal/d, and SSB consumption was 222 ± 243 mL/d and 98 ± 103 kcal/d. Mean δ13C value was -19.65 ± 0.69‰, and was lower in children than in adolescents (-19.80 ± 0.67‰ compared with -19.56 ± 0.67‰, P = 0.002). δ13C values were similar across sessions (visit 1: -19.66 ± 0.68‰; visit 3: -19.64 ± 0.68‰; r = 0.99, P < 0.001) and were associated (P < 0.001) with intake of total AS (grams, kilocalories: r = 0.29) and SSB (milliliters, kilocalories: r = 0.35). The biomarker was able to better discriminate between high and low SSB consumers than high and low AS consumers, as demonstrated by the AUC (0.75 and 0.62, respectively). Conclusions The δ13C biomarker is a promising, minimally invasive, objective biomarker of SSB intake in children and adolescents. Further evaluation using controlled feeding designs is warranted. Registered at clinicaltrials.gov as NCT02455388.
A Proposal for a Shared Medical School Curricular Ecosystem

New digital platforms are transforming learning in higher education and providing high-quality education content at little or no cost. Educators can now reach large, even global audiences. Yet, many medical schools continue to develop and maintain custom but duplicative curricular content despite having limited faculty and financial resources. In addition, medical students are faced with a multitude of potentially unaligned curricula driven by the school, national licensing exams, and the students’ own perceived clinical training needs. The authors propose the creation of a common curricular component ecosystem that is developed around consensus-built foundational learning objectives aligned with core competencies that must be acquired by all students graduating medical school. Identifying and developing common curricula with standardized learning outcomes ideally should involve leading medical education, accreditation, and certification bodies in the United States. Curriculum component standards will be necessary to enable curriculum development, sharing, and adoption at scale. A shared medical curriculum ecosystem would free up faculty time to develop high-value teaching activities at individual medical schools. Students would benefit from a consistent education experience that better aligns with national licensure exams. A shared, core curriculum system could begin to bend the cost curve for medical education in the United States and scale internationally to help address the increasing global shortage of health care workers.
Child labor and health: a systematic literature review of the impacts of child labor on child’s health in low- and middle-income countries

Abstract Objective To summarize current evidence on the impacts of child labor on physical and mental health. Methods We searched PubMed and ScienceDirect for studies that included participants aged 18 years or less, conducted in low- and middle-income countries (LMICs), and reported quantitative data. Two independent reviewers conducted data extraction and assessment of study quality. Results A total of 25 studies were identified, the majority of which were cross-sectional. Child labor was found to be associated with a number of adverse health outcomes, including but not limited to poor growth, malnutrition, higher incidence of infectious and system-specific diseases, behavioral and emotional disorders, and decreased coping efficacy. Quality of included studies was rated as fair to good. Conclusion and recommendations Child labor remains a major public health concern in LMICs, being associated with adverse physical and mental health outcomes. Current efforts against child labor need to be revisited, at least in LMICs. Further studies following a longitudinal design, and using common methods to assess the health impact of child labor in different country contexts would inform policy making.
[A Comparison of Hospice Care Research Topics between Korea and Other Countries Using Text Network Analysis].

PURPOSE This study aimed to identify and compare hospice care research topics between Korean and international nursing studies using text network analysis. METHODS The study was conducted in four steps: 1) collecting abstracts of relevant journal articles, 2) extracting and cleaning keywords (semantic morphemes) from the abstracts, 3) developing co-occurrence matrices and text-networks of keywords, and 4) analyzing network-related measures including degree centrality, closeness centrality, betweenness centrality, and clustering using the NetMiner program. Abstracts from 347 Korean and 1,926 international studies for the period of 1998-2016 were analyzed. RESULTS Between Korean and international studies, six of the most important core keywords-"hospice," "patient," "death," "RNs," "care," and "family"-were common, whereas "cancer" from Korean studies and "palliative care" from international studies ranked more highly. Keywords such as "attitude," "spirituality," "life," "effect," and "meaning" for Korean studies and "communication," "treatment," "USA," and "doctor" for international studies uniquely emerged as core keywords in recent studies (2011~2016). Five subtopic groups each were identified from Korean and international studies. Two common subtopics were "hospice palliative care and volunteers" and "cancer patients. " CONCLUSION For a better quality of hospice care in Korea, it is recommended that nursing researchers focus on study topics of patients with non-cancer disease, children and family, communication, and pain and symptom management.
Drug survival and postdrug survival of first‐line immunosuppressive treatments for atopic dermatitis: comparison between methotrexate and cyclosporine

Cyclosporine and methotrexate are the two preferred first‐line immunosuppressive treatments in atopic dermatitis. The aim of this study was to compare the treatment profiles of methotrexate and cyclosporine in daily practice as the first‐line immunosuppressive treatment in atopic dermatitis, using two survival analyses, ‘drug survival’ (time on the drug) and ‘postdrug survival’ (time between two drugs).
Performance analysis and interference cancellation for heterogeneous network with massive MIMO

Heterogenous network and massive MIMO can significantly enhance spectral and energy efficiency of wireless networks and therefore have attracted much attention. In this paper, we analyze the performance of a downlink heterogenous network where a macro base station (BS) is equipped with a large number of antennas. Lower bounds on ergodic rates for macro and pico users are derived when macro and pico BSs employ zero forcing and matched filter precoding matrix, respectively. To utilize high degrees of freedom introduced by massive MIMO, interference cancellation can be used to further improve the network performance. In this way, the macro BS can project signals for macro users to the null space of interference channels from macro BS to pico users. To maximize the overall network transmission rate by selecting the interference-free pico users, an algorithm based on statistical channel state information is developed, which can reduce the backhaul overhead. The analytical results are confirmed and the performance of the proposed algorithm is demonstrated by computer simulation.
Fast-spiking GABA circuit dynamics in the auditory cortex predict recovery of sensory processing following peripheral nerve damage

Cortical neurons remap their receptive fields and rescale sensitivity to spared peripheral inputs following sensory nerve damage. To address how these plasticity processes are coordinated over the course of functional recovery, we tracked receptive field reorganization, spontaneous activity, and response gain from individual principal neurons in the adult mouse auditory cortex over a 50-day period surrounding either moderate or massive auditory nerve damage. We related the day-by-day recovery of sound processing to dynamic changes in the strength of intracortical inhibition from parvalbumin-expressing (PV) inhibitory neurons. Whereas the status of brainstem-evoked potentials did not predict the recovery of sensory responses to surviving nerve fibers, homeostatic adjustments in PV-mediated inhibition during the first days following injury could predict the eventual recovery of cortical sound processing weeks later. These findings underscore the potential importance of self-regulated inhibitory dynamics for the restoration of sensory processing in excitatory neurons following peripheral nerve injuries.

Combination analysis of NOS3, ABCB1 and IL23R polymorphisms with alcohol-induced osteonecrosis of the femoral head risk in Chinese males

Background Common variants of multiple genes played a crucial role in osteonecrosis of the femoral head (ONFH) onset which was proved by many previous reports. We hypothesized that polymorphisms in NOS3, ABCB1 and IL23R were related to individual differences in alcohol sensitivity and the development of alcohol-induced ONFH. Methods In this case-control study, we evaluated 8 SNPs in three genes in the Chinese Han population including 355 male cases and 355 healthy male controls. These SNPs were genotyped by Sequenom MassARRAY RS1000. To identify their relationship with alcohol-induced ONFH susceptibility using χ2 test and genetic model analysis. Results We found an association with alcohol-induced ONFH susceptibility for 4 SNPs (rs743506, rs3918184, rs13233308 and rs6693831) in three genes after adjusted by age. The genotype “G/A” of rs743506 in NOS3 gene acts as a risk factor in genotype (P = 0.003), dominant (P = 0.048), recessive (P = 0.005) and additive model(P = 0.006); The genotype “T/C” of rs3918184 in NOS3 gene acts as a risk factor in genotype (P = 0.012) and recessive model (P = 0.009); The genotype “T/C” of rs13233308 in ABCB1 gene acts as a risk factor in genotype (P = 0.038) and additive model(P = 0.041); The genotype “T/C” of rs6693831 in IL23R gene acts as a protective factor in genotype model (P = 0.046). Conclusions This study provides evidence for three alcohol-induced ONFH susceptibility genes (NOS3, ABCB1 and IL23R) in Chinese males and polymorphisms of them may be associated with alcohol-induced ONFH risk.
Learning over Sets using Boosted Manifold Principal Angles (BoMPA)

In this paper we address the problem of classifying vector sets. We motivate and introduce a novel method based on comparisons between corresponding vector subspaces. In particular, there are two main areas of novelty: (i) we extend the concept of principal angles between linear subspaces to manifolds with arbitrary nonlinearities; (ii) it is demonstrated how boosting can be used for application-optimal principal angle fusion. The strengths of the proposed method are empirically demonstrated on the task of automatic face recognition (AFR), in which it is shown to outperform state-of-the-art methods in the literature.
Assessment of Suicidal Ideation and Behavior: Report of the International Society for CNS Clinical Trials and Methodology Consensus Meeting.

OBJECTIVE To develop consensus recommendations for assessment of suicidal ideation/suicidal behavior (SI/SB) in clinical trials. PARTICIPANTS Stakeholders from academia, industry, regulatory agencies, National Institutes of Health, National Institute of Mental Health, and patient advocacy organizations participated in a consensus meeting that was sponsored by the International Society for CNS Clinical Trials and Methodology and held November 17-18, 2015. Prior to the meeting, teams of experts identified key areas of consensus and dissent related to SI/SB. The most critical issues were presented and discussed in the consensus meeting. EVIDENCE Literature reviews and a pre-meeting survey were conducted. Findings were discussed in pre-meeting working group sessions and at the consensus meeting. CONSENSUS PROCESS Five pre-meeting working groups reviewed (1) nomenclature and classification schemes for SI/SB, (2) detection and assessment of SI/SB, (3) analysis of SI/SB data, (4) design of clinical trials for new treatments of SI/SB, and (5) public health approaches to SI/SB. A modification of the RAND/UCLA Appropriateness Method was used to combine review of scientific evidence with the collective views of experts and stakeholders to reach the final consensus statements. After discussion, all attendees voted using an electronic interactive audience response system. Areas of agreement and areas of continuing dissent were recorded. CONCLUSIONS All 5 working groups agreed that a major barrier to advancement of the field of SI/SB research and the development of new treatments for SI/SB remains the lack of a universally accepted standardized nomenclature and classification system. Achieving alignment on definitions and classification of suicide-related phenomena is critical to improving the detection and assessment of SI/SB, the design of clinical trials for new treatments, and effective public health interventions.
Opioid Use in Children and Adolescents After Anterior Cruciate Ligament Repair

ABSTRACT Opioid overdose is a leading cause of death from unintentional injury in the United States. When more opioids are prescribed than needed, leftover opioids may be misused if not properly disposed. The purpose of this study is to describe the opioid use of subjects (aged 13–21 years) after an anterior cruciate ligament (ACL) repair. After obtaining IRB approval, we obtained consent from 100 subjects (over an 8-month period) undergoing ACL reconstructions performed by five sports medicine surgeons. The mean age of enrolled subjects was 16 years, most were female (60%) and white (72%). While in the hospital, many subjects received the following: a regional anesthetic technique through a single shot femoral nerve block (50%); ketorolac (89%); and acetaminophen (84%). One week after surgery, we interviewed subjects to determine the amount of opioid used (36%) as compared to the amount prescribed.
The Expansion Segments of 28S Ribosomal RNA Extensively Match Human Messenger RNAs

Eukaryote ribosomal RNAs (rRNAs) have expanded in the course of phylogeny by addition of nucleotides in specific insertion areas, the expansion segments. These number about 40 in the larger (25–28S) rRNA (up to 2,400 nucleotides), and about 12 in the smaller (18S) rRNA (<700 nucleotides). Expansion of the larger rRNA shows a clear phylogenetic increase, with a dramatic rise in mammals and especially in hominids. Substantial portions of expansion segments in this RNA are not bound to ribosomal proteins, and may engage extraneous interactants, including messenger RNAs (mRNAs). Studies on the ribosome-mRNA interaction have focused on proteins of the smaller ribosomal subunit, with some examination of 18S rRNA. However, the expansion segments of human 28S rRNA show much higher density and numbers of mRNA matches than those of 18S rRNA, and also a higher density and match numbers than its own core parts. We have studied that with frequent and potentially stable matches containing 7–15 nucleotides. The expansion segments of 28S rRNA average more than 50 matches per mRNA even assuming only 5% of their sequence as available for such interaction. Large expansion segments 7, 15, and 27 of 28S rRNA also have copious long (≥10-nucleotide) matches to most human mRNAs, with frequencies much higher than in other 28S rRNA parts. Expansion segments 7 and 27 and especially segment 15 of 28S rRNA show large size increase in mammals compared to other metazoans, which could reflect a gain of function related to interaction with non-ribosomal partners. The 28S rRNA expansion segment 15 shows very high increments in size, guanosine, and cytidine nucleotide content and mRNA matching in mammals, and especially in hominids. With these segments (but not with other 28S rRNA or any 18S rRNA expansion segments) the density and number of matches are much higher in 5′-terminal than in 3′-terminal untranslated mRNA regions, which may relate to mRNA mobilization via 5′ termini. Matches in the expansion segments 7, 15, and 27 of human 28S rRNA appear as candidates for general interaction with mRNAs, especially those associated with intracellular matrices such as the endoplasmic reticulum.
Therapeutic role of rifampicin in Alzheimer's disease

Rifampicin exerts significant brain protective functions in multiple experimental models. Here we summarize the underlying mechanisms of the neuroprotective and pro‐cognitive effects of rifampicin that are mediated by its anti‐inflammatory, anti‐tau, anti‐amyloid, and cholinergic effects. Beyond suggesting that rifampicin shows strong brain protective effects in preclinical models of Alzheimer's disease, we also provide substantial clinical evidence for the neuroprotective and pro‐cognitive effects of rifampicin. Future neuroimaging studies combined with clinical assessment scores are the following steps to be taken in this field of research.
The role of nitric oxide pathway in arginine transport and growth of IPEC-1 cells

L-Arginine itself and its metabolite-nitric oxide play great roles in intestinal physiology. However, the molecular mechanism underlying nitric oxide pathway regulating L-Arginine transport and cell growth is not yet fully understood. We report that inhibition of nitric oxide synthase (NOS) significantly induced cell apoptosis (p < 0.05), and promoted the rate of Arginine uptake and the expressions of protein for CAT-2 and y+LAT-1 (p < 0.05), while reduced protein expression of CAT-1. And NOS inhibition markedly decreased the activation of mammalian target of rapamycin (mTOR) and PI3K-Akt pathways by Arginine in the IPEC-1 cells (p < 0.05). Taken together, these data suggest that inhibition of NO pathway by L-NAME induces a negative feedback increasing of Arginine uptake and CAT-2 and y+LAT-1 protein expression, but promotes cell apoptosis which involved inhibiting the activation of mTOR and PI3K-Akt pathways.

Effect of bovine pellucid zone 3 monoclonal antibodies on B cell lymphoma 2 expressions of granulosa cell and mice (Mus musculus) follicle diameter

Objective: To evaluate the effects of pellucid zone 3 monoclonal antibodies against B-cell lymphoma 2 (BCL-2) expression and mice follicle diameter at various time periods. Methods: The animal model of this study was 36 Balb/c mice (Mus musculus). A true experimental design was used with a post-test only control group approach. BCL-2 expression was observed using immunohistochemistry, while the follicle diameter was observed by haematoxylin-eosin staining. The data was analyzed using nested ANOVA to compare the results of the mean expression of BCL-2 on the 5th and 20th day of observation in the pre-antral and antral follicle between the control and treatment groups. Results: No significant differences were found in BCL-2 gene expression. There were also no significant differences in BCL-2 expression on the 10th day of pre-antral follicle analysis. Moreover, there were no significant differences between the mean follicle diameter on the 5th, 10th, and 20th day of pre-antral and antral follicle development between the control and treatment groups. The addition of bovine pellucid zone 3 (bZP3) monoclonal antibodies on the 5th and 20th day of observation did not decrease the expression of BCL-2 gene in the pre-antral and antral follicle of mice. Administering bZP3 monoclonal antibodies on the 10th day of observation did not affect BCL-2 expression in the pre-antral follicle but did decrease BCL-2 expression in the antral follicle. Supplying bZP3 monoclonal antibodies on the 5th, 10th and 20th day did not affect the diameter of pre-antral and antral follicles of the mice. Conclusion: The monoclonal antibodies bovine zona pelusida 3 has the potential to be developed as a safe immunocontraception preparation.
An incremental/decremental Delaunay mesh-generation framework for image representation

A flexible new mesh-generation framework for image representation is proposed, based on Delaunay triangulations. It is shown that this framework can be used to form a postprocessing optimization step that, when added to other previously-proposed methods, yields meshes of much greater quality. A new mesh-generation method, called IDDT, is also derived using the proposed framework, and shown to yield meshes of much better quality than those produced by previously-proposed methods as well as optimized versions of these methods constructed with the proposed framework.
