Invasive meningococcal disease has high morbidity and mortality, with infants and young children among those at greatest risk. This phase III, open-label, randomised study in toddlers aged 12–23 months evaluated the immunogenicity and safety of meningococcal tetanus toxoid-conjugate vaccine (MenACYW-TT), a tetanus toxoid conjugated vaccine against meningococcal serogroups A, C, W and Y, when coadministered with paediatric vaccines (measles, mumps and rubella [MMR]; varicella [V]; 6-in-1 combination vaccine against diphtheria, tetanus, pertussis, polio, hepatitis B and Haemophilus influenzae type b [DTaP-IPV-HepB-Hib] and pneumococcal conjugate vaccine [PCV13])(NCT03205371). Immunogenicity to each meningococcal serogroup was assessed by serum bactericidal antibody assay using human complement (hSBA). Vaccine safety profiles were described up to 30 days post-vaccination. A total of 1183 participants were enrolled. The proportion with seroprotection (hSBA ≥1:8) to each meningococcal serogroup at Day 30 was comparable between the MenACYW-TT and MenACYW-TT + MMR + V groups (≥92 and ≥96%, respectively), between the MenACYW-TT and MenACYW-TT + DTaP-IPV-HepB-Hib groups (≥90% for both) and between the MenACYW-TT and MenACYW-TT + PCV13 groups (≥91 and ≥84%, respectively). The safety profiles of MenACYW-TT, and MMR + V, DTaP-IPV-HepB-Hib, and PCV13, with or without MenACYW-TT, were generally comparable. Coadministration of MenACYW-TT with paediatric vaccines in toddlers had no clinically relevant effect on the immunogenicity and safety of any of the vaccines.
The AD 775 peak in Δ14C (henceforth, M12) was first measured by Miyake et al. and has since been confirmed globally. Here we present earlywood and latewood Δ14C values from tree rings of pinyon pine (Pinus edulis) from Mummy Cave, Canyon de Chelly National Monument, Chinle, Arizona, USA, for the period AD 770–780. These data reconfirm the timing of M12 and show a small rise in Δ14C in AD 774 latewood. Allowing for the delay in lateral transfer of radiocarbon produced at high latitude, this suggests that 14C peak production occurred in late winter or spring of AD 774. Additionally, Δ14C decreased slightly in the earlywood of AD 775 and increased in the latewood of AD 775 to a higher level than that observed in AD 774.
Patulous Eustachian tube appears to be caused by a concave defect in the anterolateral wall of the tubal valve of the Eustachian tube. This study aimed to compare the clinical features of patulous Eustachian tube patients with or without a defect in the anterolateral wall of the tubal valve.
Sixty-six patients with a patulous Eustachian tube completed a questionnaire, which was evaluated alongside endoscopic findings of the tympanic membrane, nasal cavity and Eustachian tube orifice.
Females were more frequently diagnosed with a patulous Eustachian tube, but the valve defect was more common in males (p = 0.007). The ratio of patulous Eustachian tube patients with or without defects in the anterolateral wall of the tubal valve was 1.6:1. Weight loss in the previous six months and being refractory to conservative management were significantly associated with the defect (p = 0.035 and 0.037, respectively). Symptom severity was significantly higher in patients with the defect.
Patulous Eustachian tube patients without a defect in the anterolateral wall of the tubal valve can be non-surgically treated more often than those with the defect. Identification of the defect could assist in making treatment decisions for patulous Eustachian tube patients.
A systematic review of studies related to the psychological characteristics of Sasang typology, a traditional Korean personalized medicine utilizing acupuncture and medical herbs, was conducted with the goal of delineating generalizable psychological profiles of each types using western academic traditions.
Journal articles were collected using 5 electronic database systems in the United States and Korea, and 21 peer reviewed research articles with psychometric inventories were included. Due to the heterogeneity of the studies, the present study sought to report the mutual relevance of the studies based on research results pertaining to the correlation between psychological assessment instruments.
Results of the review indicate that two super-factors of Eysenck, Extraversion and Neuroticism, serve as the foundation in regards to delineating personality constructs, such that the So-Yang type scored high on the Extraversion dimension and low on the Neuroticism dimension compared to the So-Eum type. Current studies with Cloninger's Temperament and Character Inventory also showed that the Novelty Seeking and the Harm Avoidance can be related to the So-Yang and the So-Eum type, respectively.
The present systematic review indicates that Neo-Confucianism-based Sasang typology shares similarities with the western psychological tradition. There is an urgent need to study similarities and differences between both of them in multiple perspectives including mechanism of action beneath the medical intervention. The Bio-psycho-social basis of the Sasang typology can guide us to the temperament-based personalized integrative medicine covering western orthodox and traditional oriental medicine.
Both trauma-focused cognitive behaviour therapy and antidepressant medication are regarded as the first line treatments for post-traumatic stress disorder (PTSD). However, little is known about sequential or combined efficacy of these two different treatment options. This prospective study examined the add-on efficacy of eye movement desensitization and reprocessing (EMDR) therapy among adult civilians with PTSD who continued to be symptomatic after antidepressant treatment.
Adult patients with PTSD at a specialized trauma clinic who received treatment doses of antidepressants for more than 12 weeks were recruited; definition of symptomatic PTSD was a total score > 40 on the Clinician-administered PTSD Scale (CAPS). The CAPS and the global improvement from Clinical Global Impression (CGI) were rated prior to EMDR, after termination and six months follow-up.
A total of 15 patients underwent an average of six sessions of EMDR and 7 (47%) of 15 no longer met the criteria for PTSD and 10 (67%) were given status of very much or much improved. The CAPS scores and significantly decreased after EMDR therapy (paired t = 7.38, df = 14, P < 0.0001).
These results indicate that EMDR or trauma-focused CBT can be successfully added to those who failed to improve after initial pharmacotherapy for PTSD. Further studies are needed to explore the best sequence or components of therapies in the treatment of PTSD.

This research examined gender variations in depressive mood for high school students affected by emotional upset and how such depressive mood affect their sleep quality.
Research was conducted from September 2015 to October 2015. Both males and females were divided into normal group and depressive group by Zung Self-rating Depression Scale (ZSDS). Each group adopted the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality.
Analysis was made on a total of 155 students, which were 83 male students and 72 female. The average ZSDS for all high school students was 43.38 and the average PSQI was 5.39. The number of male students in the normal and depressive group who were diagnosed with sleep disorder were 2 (3.8%) and 9 (29.0%), respectively (P < 0.05). But the number of female students in the normal and depressive group who were diagnosed with sleep disorder were 11 (32.4%) and 33 (86.8%), respectively (P < 0.05). Both males and females shared a meaningful result over sleep latency, sleep disturbance, use of sleep medication, and daytime functional disturbance among 7 items of PSQI for sleep quality, and female students had a significantly meaningful result over sleep duration, habitual sleep effects (P < 0.05).
This research showed that sleep quality of all high school students was not too bad but it can be problematic for those with depressive mood. Especially, female students were diagnosed with sleep disorder more than male students.

Although a number of studies have examined the relationship between depression and obesity, it is still insufficient to establish the specific pattern of relationship between depression and body mass index (BMI) categories. Thus, this study was aimed to investigate the relationship between depression and BMI categories.
A cross-sectional study was conducted for a cohort of 159,390 Korean based on Kangbuk Samsung Health Study (KSHS). Study participants were classified into 5 groups by Asian-specific cut-off of BMI (18.5, 23, 25 and 30 kg/m2). The presence of depression was determined by Center for Epidemiologic Studies-Depression scales (CES-D) = 16 and = 25. The adjusted odd ratios (ORs) for depression were evaluated by multiple logistic regression analysis, in which independent variable was 5 categories of BMI and dependent variable was depression. Subgroup analysis was conducted by gender and age.
When normal group was set as a reference, the adjusted ORs for depression formed U-shaped pattern of relationship with BMI categories [underweight: 1.31 (1.14–1.50), overweight: 0.94 (0.85–1.04), obese group: 1.01 (0.91–1.12), severe obese group: 1.28 (1.05–1.54)]. This pattern of relationship was more prominent in female and young age group than male and elderly subgroup. BMI level with the lowest likelihood of depression was 18.5 kg/m2 to 25 kg/m2 in women and 23 kg/m2 to 25 kg/m2 in men.
There was a U-shaped relationship between depression and BMI categories. This finding suggests that both underweight and severe obesity are associated with the increased risk for depression.
The objective of this family-based whole exome sequencing (WES) is to examine genetic variants of autism spectrum disorder (ASD) in Korean population.
The probands with ASD and their biological parents were recruited in this study. We ascertained diagnosis based on DSM-5™ criteria, using Autism Diagnostic Observation Schedule and Autism Diagnostic Interview–Revised. We selected probands with typical phenotypes of ASD both in social interaction/communication and repetitive behaviour/limited interest domains, with intellectual disability (IQ < 70), for attaining homogeneity of the phenotypes. First, we performed WES minimum 50× for 13 probands and high-coverage pooled sequencing for their parents. We performed additional WES for 38 trio families, at least 100× depth. De novo mutations were confirmed by Sanger sequencing. All the sequence reads were mapped onto the human reference genome (hg19 without Y chromosome). Bioinformatics analyses were performed by BWA-MEM, Picard, GATK, and snpEff for variant annotation. We selected de novo mutation candidates from probands, which are neither detected in two pooled samples nor both parents.
Fifty-one subjects with ASD (5 females, 40∼175 months, mean IQ 42) and their families were included in this study. We discovered 109 de novo variants from 46 families. Twenty-nine variants are expected to be amino acid changing, potentially causing deleterious effects. We assume CELSR3, MYH1, ATXN1, IDUA, NFKB1, and C4A/C4B may have adverse effect on central nerve system.
We observed novel de novo variants which are assumed to contribute to development of ASD with typical phenotypes and low intelligence in WES study.

Infectious diseases, such as Helicobacter pylori, which produce systemic inflammation may be one key factor in the onset of autoimmunity. The association between H. pylori and antinuclear antibodies (ANA), a marker of autoimmunity, has been understudied. Data from the 1999–2000 National Health and Nutrition Examination Survey were used to evaluate the cross-sectional association between H. pylori seroprevalence and ANA positivity in US adults aged ≥20 years. ANA was measured in a 1:80 dilution of sera by indirect immunofluorescence using HEp-2 cells (positive ⩾3). H. pylori immunoglobulin G enzyme-linked immunosorbent assays were used to categorise individuals as seropositive or seronegative. H. pylori seropositivity and ANA positivity were common in the adult US population, with estimated prevalences of 33.3% and 9.9%, respectively. Both were associated with increasing age. H. pylori seropositivity was associated with higher odds of ANA (prevalence odds ratio = 1.89, 95% confidence interval = 1.08–3.33), adjusted for age, sex, race/ethnicity, educational attainment and body mass index. H. pylori infection may be one key factor in the loss of self-tolerance, contributing to immune dysfunction.
To investigate the association between parity and the risk of incident dementia in women.
We pooled baseline and follow-up data for community-dwelling women aged 60 or older from six population-based, prospective cohort studies from four European and two Asian countries. We investigated the association between parity and incident dementia using Cox proportional hazards regression models adjusted for age, educational level, hypertension, diabetes mellitus and cohort, with additional analysis by dementia subtype (Alzheimer dementia (AD) and non-Alzheimer dementia (NAD)).
Of 9756 women dementia-free at baseline, 7010 completed one or more follow-up assessments. The mean follow-up duration was 5.4 ± 3.1 years and dementia developed in 550 participants. The number of parities was associated with the risk of incident dementia (hazard ratio (HR) = 1.07, 95% confidence interval (CI) = 1.02–1.13). Grand multiparity (five or more parities) increased the risk of dementia by 30% compared to 1–4 parities (HR = 1.30, 95% CI = 1.02–1.67). The risk of NAD increased by 12% for every parity (HR = 1.12, 95% CI = 1.02–1.23) and by 60% for grand multiparity (HR = 1.60, 95% CI = 1.00–2.55), but the risk of AD was not significantly associated with parity.
Grand multiparity is a significant risk factor for dementia in women. This may have particularly important implications for women in low and middle-income countries where the fertility rate and prevalence of grand multiparity are high.
Light Detection and Ranging (LiDAR) is a primary sensor for autonomous vehicles to recognize surroundings. It detects near-infrared (NIR) light pulses, typically at 905nm, which is emitted and reflected by surrounding objects. Here, the fact of the matter is that conventional black or dark-tone cars with extremely low NIR reflection are hard to be detected by LiDAR and endanger the future highway. In this work, we propose to use platelet-shaped effect pigments with visible absorption and NIR reflectivity. Copper(Ⅱ) oxide and Silicon dioxide multilayer are theoretically investigated with different numbers of layers and thicknesses. The optimized structures appear various dark-tone colors with high NIR-reflectivity over 90%.
The goal of this chapter is to address how urban dynamics at the neighborhood level are linked to children’s development. We first review trends in the spatial concentration of poverty and inequality in the United States in recent decades. Then, we turn to theoretical models describing how local communities, with a focus on urban settings, influence children’s development. We then cover methodological issues and focus on one critical issue, selection bias, and then briefly review study designs as related to this challenge. Finally, we provide an overview of empirical studies linking neighborhood, socioeconomic conditions, and children’s development, notably their educational, behavioral, and socioemotional outcomes.
Philosophers through the ages have stressed time as a critical variable in life, and developmentalists today pretend to a lifespan framework. Paradoxically, many construals of time are still neglected in developmental science. This chapter focuses on time and fleshes out three developmental perspectives on time: the chronosystem from the bioecological systems framework, transaction, and specificity.
Bioecological systems theory characterizes development as a joint function of process, person, context, and time. The principle of transaction in development asserts that characteristics of individuals shape their experiences, and reciprocally experiences shape the characteristics of individuals, through time. Finally, the specificity principle contends that understanding lifespan development depends critically on what is studied in whom, how, and when. Time fits integrally into each prevailing developmental perspective.
In this chapter, we argue that the timing of societal events in an individual’s life plays a major role in shaping that life through interacting developmental processes at multiple levels. We focus on classic research by Elder showing how two such events in historical proximity dramatically altered the lives of California children who were born at opposite ends of the 1920s, 1920–21 and 1928–29, the Great Depression of the 1930s followed by World War II (1941–45) and the Korean War (1950–53). We employ insights from both Elder’s cohort historical life course approach and developmental science including recent work on developmental neuroscience to understand the life-long impact of exposure to events that occur at different times in life, and the mechanisms through which these exposures may influence development, as well as experiences that may provide turning points in development.
In this opening chapter we provide a chronology of the relatively recent recognition that an understanding of children’s lives across time requires that context in terms of historical time and place also needs to consider culture . Early efforts often failed to recognize this fundamental premise and instead studied children out of context.
The emergence of the life course perspective with its recognition of the centrality of changing historical contexts as necessary for an adequate understanding of children’s development was a major step forward in theorizing about children’s development. Moreover, in the past several decades, the life course perspective has also evolved and now recognizes the role of both individual and collective agency in shaping both individual outcomes and those at other levels of analysis. Moreover, as prior work has long recognized, it is increasingly accepted that secular changes co-occur and often come as a package.
For example, war, famine, migration, and economic hardship generally operate together. We also underscore the increasing appreciation of cross-disciplinary dialogue as necessary for understanding issues such as children’s genetic influences and how they are constrained in their expression by historical and environmental factors.
