Abstract
Pediatric glioma therapy has evolved to delay or eliminate radiation for low-grade tumors. This study examined these temporal changes in therapy with long-term outcomes in adult survivors of childhood glioma. Among 2,501 5-year survivors of glioma in the Childhood Cancer Survivor Study diagnosed 1970-1999, exposure to radiation decreased over time. Survivors from more recent eras were at lower risk of late mortality (≥5 years from diagnosis), severe/disabling/life-threatening chronic health conditions (CHCs) and subsequent neoplasms (SNs). Adjusting for treatment exposure (surgery only, chemotherapy, or any cranial radiation) attenuated this risk (for example, CHCs (1990s versus 1970s), relative risk (95% confidence interval), 0.63 (0.49-0.80) without adjustment versus 0.93 (0.72-1.20) with adjustment). Compared to surgery alone, radiation was associated with greater than four times the risk of late mortality, CHCs and SNs. Evolving therapy, particularly avoidance of cranial radiation, has improved late outcomes for childhood glioma survivors without increased risk for late recurrence.

Abstract
OBJECTIVE Childhood cancer survivors are at risk for hypogonadism. The impact of hypogonadism on neurocognitive impairment and emotional distress in the non-cancer population has been shown; however, the relationship among the childhood cancer survivor population is unknown. We aimed to evaluate the contribution of hypogonadism to neurocognitive impairment and emotional distress among survivors. DESIGN Cross-sectional study using retrospective cohort. METHODS In total, 3628 survivors who completed standard neurocognitive tests (six domains: processing speed, memory, executive function, attention, academics, and global cognition) and self-reported emotional distress were included in our study. Participants were stratified by sex and gonadal status. Outcomes were compared between hypogonadal and eugonadal groups by multivariable analysis, adjusting for established predictors, and mediation analyses to determine the direct/indirect effects of hypogonadism on outcomes. RESULTS The hypogonadal group exhibited a higher prevalence of neurocognitive impairment across domains, but no difference in emotional distress. Hypogonadal females exhibited higher relative risk (1.7, 95% CI, 1.2-2.5) for impaired visual processing speed, compared to eugonadal females after adjusting for cancer-related variables. In mediation models, hypogonadism had a significant direct (P < .01) and indirect (from P < .01) impact on impairment in visual processing speed among females. Males demonstrated direct (P = .03) and indirect (P = .04) impact of hypogonadism on motor processing speed. CONCLUSION Processing speed may be the most vulnerable neurocognitive domain associated with hypogonadism in survivors, while other domains were mainly impacted by cancer-related variables. Our findings support the need for further evaluation of the impact of sex hormone replacement therapy on neurocognitive function.

Abstract
BACKGROUND Treatment of childhood glioma has evolved to reduce radiotherapy exposure with the goal of limiting late toxicity. However, the associations between treatment changes and neurocognition, and the contribution of neurocognition and chronic health conditions to attainment of adult independence, remain unknown. METHODS Adult survivors of childhood glioma diagnosed in 1970-1999 in the Childhood Cancer Survivor Study (n = 1284; median [minimum-maximum] 30 [18-51] years of age at assessment; 22 [15-34] years from diagnosis) self-reported neurocognitive impairment and chronic health conditions. Multivariable models evaluated associations between changes in treatment exposures (surgery only, chemotherapy [with or without surgery], cranial radiation [with or without chemotherapy and/or surgery]), and neurocognitive impairment. Latent class analysis with 5 indicators (employment, independent living, assistance with routine and/or personal care needs, driver's license, marital or partner status) identified classes of functional independence. Path analysis tested associations among treatment exposures, neurocognitive impairment, chronic health conditions, and functional independence. Statistical tests were 2-sided. RESULTS Cranial radiation exposure decreased over time (51%, 1970s; 46%, 1980s; 27%, 1990s]. However, compared with siblings, survivors with any treatment exposure were at elevated risk for neurocognitive impairment, including surgery only (eg, memory: relative risk = 2.22; task efficiency: relative risk = 1.88; both P < .001). Three classes of functional independence were identified: independent (58%), moderately independent (20%), and nonindependent (22%). Cranial radiation was associated with nonindependence through impaired task efficiency (β = 0.06), sensorimotor (β = 0.06), and endocrine (β = 0.10) chronic health conditions and through the associations between these conditions and task efficiency (each β = 0.04). Sensorimotor and endocrine chronic health conditions were associated with nonindependence through memory. CONCLUSION Most long-term glioma survivors achieve adult independence. However, functional nonindependence is associated with treatment-related neurocognitive impairment and chronic health conditions.

Abstract
Objective: To obtain the diversity and abundance of fast-growing bacteria in the surface water of the northeast coast of Hainan Island in China, different cultivation methods were employed. This study also aims to provide a reference for isolating bacterial samples from seawater sources and preventing marine-derived pathogens. Methods: Based on the principles of taxonomic design, surface seawater samples were collected from six locations along the northeast coast of Hainan Island in China in March, June, October, and December 2021. Then, bacterial enrichment was performed based on traditional cultivation methods for Salmonella, Vibrio, Burkholderia pseudomallei, Actinomycetes, and general marine bacteria. After that, bacterial species identification was conducted by 16S rDNA amplicon sequencing and metagenomic sequencing. Results: A total of 1 151 fast-growing cultivable bacteria belonging to 66 genera and 213 species were identified using five different culture protocols. In different cultivation protocols, Bacillus and Klebsiella demonstrated extensive discriminatory advantages and ranked among the top genera in terms of abundance. Protocol 1 had Escherichia, Klebsiella, and Citrobacter as dominant genera. Pathogenic bacteria detected by protocol 1 included Klebsiella pneumoniae and Escherichia coli, with 37 and 29 strains respectively, while Salmonella enterica was uniquely detected with seven isolates. Proteus, Enterococcus, and Providencia were the dominant genera in protocol 2, and Proteus mirabilis was the most abundant pathogenic bacteria detected with 66 isolates. Vibrio cholerae was uniquely detected with six isolates at a higher abundance. Klebsiella, Escherichia, and Acinetobacter were the dominant genera in protocol 3, and Klebsiella pneumoniae was the most abundant pathogenic bacteria detected with 53 isolates, while Acinetobacter nosocomialis was uniquely detected with seven isolates. Vibrio and Pseudoalteromonas were the dominant genera in protocol 4, and they showed advantages in isolating and cultivating Marine-derived Vibrio. Exiguobacterium, Staphylococcus, and Bacillus were the dominant genera in protocol 5. Bacillus cereus and Lactococcus lactis were the most abundant pathogenic bacteria detected with 20 and 15 isolates, respectively, while Lactococcus lactis was uniquely detected at higher abundance. Metagenomic sequencing showed that Klebsiella pneumoniae was significantly dominant with a gene abundance of 51.11%, followed by Alcanivorax sp. at 12.57%. Conclusion: The surface water of the northeast coast of Hainan Island in China exhibits a rich diversity of bacteria, with Klebsiella pneumoniae being highly abundant in the studied area. Different cultivation methods demonstrate distinct selective advantages in culturing bacterial genera and pathogens. Therefore, it is necessary to optimize cultivation conditions for specific marine bacteria.

Abstract
OBJECTIVES We aimed to clinically characterize the health, neurocognitive, and physical function outcomes of curative treatment of Wilms tumor. METHODS Survivors of Wilms tumor (n = 280) participating in the St. Jude Lifetime Cohort, a retrospective study with prospective follow-up of individuals treated for childhood cancer at St. Jude Children's Research Hospital, were clinically evaluated and compared to age and sex-matched controls (n = 625). Health conditions were graded per a modified version of the National Cancer Institute's Common Terminology Criteria for Adverse Events. Standardized neurocognitive testing was graded by using age-adjusted z-scores. Impaired physical function was defined by age- and sex-matched z-scores >1.5 SD below controls. Modified Poisson regression was used to compare the prevalence of conditions and multivariable logistic regression to examine treatment associations. RESULTS Median age at evaluation was similar between survivors and controls (30.5 years [9.0-58.0] and 31.0 [12.0-70.0]). Therapies included nephrectomy (100%), vincristine (99.3%), dactinomycin (97.9%), doxorubicin (66.8%), and abdominal (59.3%) and/or chest radiation (25.0%). By age 40 years, survivors averaged 12.7 (95% confidence interval [CI] 11.7-13.8) grade 1-4 and 7.5 (CI: 6.7-8.2) grade 2 to 4 health conditions, compared to 4.2 (CI: 3.9-4.6) and 2.3 (CI: 2.1-2.5), respectively, among controls. Grade 2 to 4 endocrine (53.9%), cardiovascular (26.4%), pulmonary (18.2%), neurologic (8.6%), neoplastic (7.9%), and kidney (7.2%) conditions were most prevalent. Survivors exhibited neurocognitive and physical performance impairments. CONCLUSIONS Wilms tumor survivors experience a threefold higher burden of chronic health conditions compared to controls and late neurocognitive and physical function deficits. Individualized clinical management, counseling, and surveillance may improve long-term health maintenance.

Abstract
PURPOSE: Pediatric low-grade glioma therapy has evolved to delay or eliminate radiation. The impact of therapy changes on long-term outcomes remains unknown. METHODS: Cumulative incidence of late mortality (death >5 years from diagnosis), subsequent neoplasms (SNs), and chronic health conditions (CHCs, CTCAE grading criteria) were evaluated in the Childhood Cancer Survivor Study among 5-year survivors of glioma diagnosed 1970-1999. Outcomes were evaluated by diagnosis decade and by treatment exposures received ≤5 years following diagnosis (surgery-only, chemotherapy ± surgery, and cranial radiation ± surgery or chemotherapy). Relative risk (RRs) with 95%CIs estimated long-term outcomes using multivariable piecewise exponential models. RESULTS: Among 2,684 eligible survivors (age at diagnosis (median [range]), 7 years [0-20 years]; time from diagnosis, 24 years [5-48 years]), exposure to cranial radiation decreased [51% (1970s), 45% (1980s), 25% (1990s)] along with late tumor recurrence (>5 & ≤15 years from diagnosis) [9.8% (1970s), 8.8% (1980s), 5.0% (1990s)]. The 15-year cumulative incidence of late mortality was 10.3% (1970s), 6.5% (1980s), and 6.0% (1990s) (p<0.001, comparison of cumulative incidence curves). The 15-year cumulative incidence of grade 3-5 CHCs was 19.7% (1970s), 17.8% (1980s), and 14.2% (1990s) (p<0.0001). A reduction in SN incidence was not observed. In multivariable analyses excluding treatment exposure, later diagnosis (1990s vs. 1970s) was associated with lower risk of late mortality, grade 3-5 CHCs and SNs. Inclusion of treatment exposure in the model attenuated the effect of diagnosis decade. Radiation or chemotherapy exposure increased risk compared to surgery alone for late mortality (radiation RR 4.95, 95%CI 3.79-6.47; chemotherapy RR 2.88, 95%CI 1.85-4.48), CHCs (radiation RR 4.02, 95%CI 3.28-4.94; chemotherapy RR 1.66, 95%CI 1.13-2.45), and SNs (radiation RR 4.02, 95%CI 3.06-6.13, chemotherapy RR 2.08, 95%CI 1.03-4.23)). CONCLUSION: Late mortality and CHCs decreased in childhood glioma survivors diagnosed from 1970-1999 largely due to therapy changes, particularly avoidance of cranial radiation, without increased late recurrence.

Abstract
PURPOSE: Survivors of pediatric glioma are at risk of developing physical and neurocognitive sequelae secondary to their tumor and its treatment. The contribution of these conditions to attainment of functional independence has not previously been examined. METHODS: 1,284 adult survivors of pediatric glioma (48% male, median [range] 30 [18-51] years at assessment, 22 [15-34] years since diagnosis) completed the CCSS Neurocognitive Questionnaire with impairment defined as scores > 90th %ile of sibling norms. Treatment exposures were categorized as surgery only, chemotherapy (± surgery), or cranial radiation (± chemotherapy/surgery). Self-reported chronic health conditions (CHCs) were graded by organ system using NCI’s CTCAE v4.3. Latent class analysis utilized six factors (employment, marital status, independent living, driver’s license, assistance with routine needs, assistance with personal care needs) to identify classes of functional independence. Multivariable modified Poisson regression evaluated relative risk (RR) of neurocognitive impairment between the classes, adjusting for sex, race, age at assessment, and age at diagnosis. Path analysis explored the impact of treatment exposures on functional independence, mediated by Grade 2-4 CHCs and neurocognitive impairment. RESULTS: Three latent classes of functional independence were identified: independent (58%), moderately independent (20%), and non-independent (22%). Compared to the independent class, non-independent survivors were at elevated risk for impaired task efficiency (RR=3.86, 95% CI, 2.97-5.01), memory (RR=2.39, 95% CI, 1.91-2.98), organization (RR=2.04, 95% CI, 1.64-2.54), and emotional regulation (RR=1.67, 95% CI, 1.30-2.15). Path analysis revealed significant direct paths from cranial radiation (β=0.14), impaired task efficiency (β=0.42), and sensorimotor (β=0.22) and endocrine conditions (β=0.24) to non-independence. Cranial radiation also was indirectly associated with non-independence through impaired task efficiency (β=0.06), and sensorimotor (β=0.06) and endocrine conditions (β=0.10). CONCLUSIONS: Neurocognitive impairment and chronic health conditions partially mediate the association between treatment exposures and attainment of independence in adulthood, identifying potential intervention targets to promote independence in long-term survivors.

Abstract
10007 Background: Therapy for pediatric low-grade glioma has evolved to delay or eliminate the need for cranial radiation. The impact of this change in approach on long-term outcomes remains unknown. Methods: Cumulative incidence of late mortality (death ≥5 years from diagnosis), subsequent neoplasms (SNs), and chronic health conditions (CHCs, graded using CTCAE criteria) were evaluated in the Childhood Cancer Survivor Study among 5-year survivors of glioma diagnosed between 1970 and 1999. Outcomes were evaluated by diagnosis decade (1970s, 1980s, 1990s) and by treatment exposure in the first five years from diagnosis [surgery only, chemotherapy (with or without surgery), and cranial radiation (with or without surgery or chemotherapy)]. Relative Risk (RRs) with 95% CIs estimated long-term outcomes using multivariable piecewise exponential models. Results: Among 2,684 eligible survivors (median age at diagnosis, 7 years [range, 0 to 20 years]; median time from diagnosis, 24 years [range, 5 to 48 years]), the proportion exposed to cranial radiation decreased from 51% (1970s) to 45% (1980s) and 25% (1990s) while the rate of recurrence within > 5 years but ≤15 years of diagnosis decreased from 9.8% (1970s) to 8.8% (1980s) and 5.0% (1990s). The 15-year cumulative incidence rate of all-cause late mortality was 10.3% (1970s), 6.5% (1980s), and 6.0% (1990s) (p < 0.001, comparison of cumulative incidence curves). The 15-year cumulative incidence rates of severe, disabling or life-threatening (grade 3-5) CHCs also decreased between 1970 and 1999: 19.7% (1970s), 17.8% (1980s), and 14.2% (1990s) (p < 0.0001). Lower rates of SN were not observed. In a multivariable analysis adjusted for age at diagnosis, attained age, race, sex and diagnosis decade, later diagnosis (1990s vs. 1970s) was associated with lower risk of late mortality (RR 0.86, 95% CI 0.74-0.99), grade 3-5 CHCs (RR 0.65, 95% CI 0.51-0.82) and SN (RR 0.64, 95% CI 0.44-0.94). In addition, when treatment exposure was added to the multivariable model, the effect of diagnosis decade was attenuated and no longer significant. Exposure to radiation or chemotherapy both increased risk compared to surgery alone: all-cause mortality (radiation RR 4.95, 95% CI 3.79-6.47; chemotherapy RR 2.88, 95% CI 1.85-4.48), grade 3-5 CHCs (radiation RR 4.02, 95% CI 3.28-4.94; chemotherapy RR 1.66, 95% CI 1.13-2.45), SNs (radiation RR 4.02, 95% CI 3.06-6.13, chemotherapy RR 2.08, 95% CI 1.03-4.23)). The effect of delayed radiation (> 1year to ≤5 years from diagnosis) on all-cause late mortality, grade 3-5 CHCs, or SNs was not different compared to radiation within one year of diagnosis. Conclusions: Late mortality and CHCs decreased in childhood glioma survivors diagnosed from 1970-1999 largely due to therapy changes, particularly avoidance of cranial radiation, without increased late recurrence.

Abstract
Long-term survivors of childhood Hodgkin lymphoma (HL) experience a high burden of chronic health morbidities. Correlates of neurocognitive and psychosocial morbidity have not been well established. A total of 1760 survivors of HL (mean ± SD age, 37.5 ± 6.0 years; time since diagnosis, 23.6 ± 4.7 years; 52.1% female) and 3180 siblings (mean age, 33.2 ± 8.5 years; 54.5% female) completed cross-sectional surveys assessing neurocognitive function, emotional distress, quality of life, social attainment, smoking, and physical activity. Treatment exposures were abstracted from medical records. Chronic health conditions were graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 4.3 (1 = mild, 2 = moderate, 3 = severe/disabling, and 4 = life-threatening). Multivariable analyses, adjusted for age, sex, and race, estimated relative risk (RR) of impairment in survivors vs siblings and, among survivors, risk of impairment associated with demographic, clinical, treatment, and grade 2 or higher chronic health conditions. Compared with siblings, survivors had significantly higher risk (all, P < .05) of neurocognitive impairment (eg, memory, 8.1% vs 5.7%), anxiety (7.0% vs 5.4%), depression (9.1% vs 7%), unemployment (9.6% vs 4.4%), and impaired physical/mental quality of life (eg, physical function, 11.2% vs 3.0%). Smoking was associated with a higher risk of impairment in task efficiency (RR, 1.56; 95% confidence interval [CI], 1.02-2.39), emotional regulation (RR, 1.84; 95% CI, 1.35-2.49), anxiety (RR, 2.43; 95% CI, 1.51-3.93), and depression (RR, 2.73; 95% CI, 1.85-4.04). Meeting the exercise guidelines of the Centers for Disease Control and Prevention was associated with a lower risk of impairment in task efficiency (RR, 0.70; 95% CI, 0.52-0.95), organization (RR, 0.60; 95% CI, 0.45-0.80), depression (RR, 0.66; 95% CI, 0.48-0.92), and multiple quality of life domains. Cardiovascular and neurologic conditions were associated with impairment in nearly all domains. Survivors of HL are at elevated risk for neurocognitive and psychosocial impairment, and risk is associated with modifiable factors that provide targets for interventions to improve long-term functional outcomes.

Abstract
This report presents new findings of exchange bias and related structural and magnetic properties in iron carbide/magnetite (Fe5C2/Fe3O4) core/shell nanoparticles. The exchange bias emerges from an energetic landscape, namely a first-order phase transition-the Verwey transition at 125 K, during which the Fe3O4 shell changes from the cubic to monoclinic structure. The phase transition leads to the exchange bias because it results in abrupt changes in magnetocrystalline anisotropy and exchange coupling. Another unique phenomenon identified in this composite system is enhanced magnetic coercivity due to the uniaxial anisotropy of the monoclinic phase. An analysis of the correlations between the observed phenomena is given based on the temperature dependence of the coercivity, the exchange bias field values, and the Verwey transition temperature.

Abstract
10038 Background: We aimed to characterize late health, neurocognitive, and physical performance outcomes among survivors of Wilms tumor. Methods: Wilms tumor survivors (n = 280), ≥ 5 years from diagnosis, participating in SJLIFE were clinically assessed along with a community control sample (n = 625). Health outcomes were graded per a modified Common Terminology Criteria for Adverse Events (grade 1 [mild] to grade 4 [life threatening]). Standardized neurocognitive testing was graded using age-adjusted z-scores. Aerobic function (six-minute walk), mobility (timed up and go) and flexibility (sit and reach) were assessed. Associations between treatment exposures and prevalent conditions were examined by multivariable logistic regression, adjusted for current age, sex and race. Results: Survivors (59% female, 73% white), median age 3 years (range 0-15) at diagnosis and 31 years (9-58) at evaluation, were comprehensively evaluated on the St. Jude campus. Two-thirds (67%) were treated with doxorubicin (median dose 175 mg/m2 range 52-490), 167 (60%) received abdominal radiation (median dose 12 Gy range 8.8-61.2) and 25% received chest radiation (12 Gy range 9-44). By age 40 years, survivors averaged 12.7 (95% confidence interval [CI] 11.7-13.8) grade 1-4 and 7.5 (CI 6.7-8.2) grade 2-4 conditions, compared to 4.2 (CI 3.9-4.6) and 2.3 (CI 2.1-2.5), respectively, among controls. The most prevalent medical conditions (grade ≥ 2) are reported in the table. Abnormal glucose metabolism was associated with abdominal radiation (relative risk [RR] 5.1 CI 1.4-19.0); restrictive pulmonary defects with chest radiation (RR 24.0 CI 3.2-180); and cardiomyopathy (RR 15.6 CI 1.9-128), pulmonary diffusion (RR 4.5 CI 1.3-15.1), and chronic kidney disease (RR 4.5 CI 1.3-16.1) with doxorubicin exposure. Survivors had a three-fold higher risk (standardized incidence ratio 3.5, CI 2.2-6.6) for subsequent neoplasms. Impairments (grade ≥ 2) in executive function (20% vs. 12%), attention (17% vs. 9%), memory (21% vs. 10%), and processing speed (20% vs. 8%) were more frequent in survivors than controls (p < 0.05). Impairments in aerobic function (13.6%), mobility (13.6%), and flexibility (11.1%) were higher than expected (p < 0.01). Significant associations were not identified between treatment exposures and neurocognitive or physical performance outcomes. Conclusions: Systematic clinical assessment identified a significant burden of chronic health conditions and previously unrecognized neurocognitive and physical performance limitations in survivors of Wilms tumor.[Table: see text]

Abstract
Objective: To understand the infectious status of Lyme disease among patients with arthritis symptoms in Hainan Province, and to provide a theoretical basis for prevention and control of Lyme disease. Methods: From 2013 to 2018, sampling surveys had been conducted in medical institutions in 8 cities in Hainan Province(Haikou, Sanya, Danzhou, Dongfang, Wenchang, Qionghai, Qiongzhong, Wuzhishan), 2 311 patients serum samples were collected with arthritis symptoms, and descriptive research were conducted base on the collected clinical data. The Indirect Fluorescent-Antibody Test (IFA) method was used for preliminary screening of Lyme disease antibody, the Western Blot (WB) method was used for IFA positive samples confirmation. Statistical analysis using χ2 test. Results: 2 311 serum samples were tested by IFA, and 166 were positive with the positive rate of 7.18%. Further confirmed by WB method, 62 samples were positive, the positive rate of Lyme disease antibody was 2.68%(62/2 311). The positive rate of Lyme disease antibody among patients with arthritis in different regions of Hainan was statistically significant (χ²=40.636,P<0.001), and the positive rate in Qiongzhong city was the highest (8.81%, 14/159). Danzhou's positive rate was the second highest, 5.62%(5/89). Dongfang city had the lowest positive rate (0.51%, 2/394). The positive rates of Lyme disease serum antibody in men and women were 2.79% (33/1 182) and 2.57% (29/1 129), respectively; the positive rates of antibodies between each age groups were in the range of 1.74% to 3.64%. The antibody positive rate of Lyme disease showed no significant difference between gender and age (χ²=0.110,P=0.740 ;χ²=1.938,P=0.747). Conclusion: Patients with arthritis symptoms caused by Borrelia burgdorferi infection were found in 8 cities in Hainan province, but the Lyme disease antibody positive rate was different among cities, with Qiongzhong County being the highest.

Abstract
Self-assembly of nanoparticles into ordered patterns is a novel approach to build up new consolidated materials with desired collective physical properties. Herein, nanoparticle assemblies of composition-modulated bimagnetic nanoparticles have been produced via slow evaporation of their colloidal suspension in the absence or presence of magnetic fields. The assemblies obtained in the presence of the magnetic fields exhibit oriented nanoparticle chains in face-centered cubic superlattice structures, compared with the hexagonal closed-packed superlattice obtained without the magnetic field. The oriented structure has an alignment of the easy magnetization axis along the chains. This alignment leads to enhanced intra-superlattice interactions. As a result, the field-induced assembly displays collective magnetic properties with significantly enhanced magnetic anisotropy, remanent magnetization and coercivity. It is also found that the bimagnetic FeCo/CoFe2O4 core/shell nanostructure enhances the intra-particle interaction and thus is beneficial for the growth of oriented assembly of nanoparticles. Furthermore, the collective magnetic behavior is evidenced by the observation of a superferromagnetic-like magnetization relaxation in the ac-susceptibility curves.

Abstract
Threatening faces are potent cues in social anxiety disorder (SAD); therefore, neural response to threatening faces, particularly regions in the "fear" circuit such as amygdala, may classify individuals with SAD. Previous studies of indirect/implicit processing of threatening faces have shown that support vector machine (SVM) pattern recognition significantly differentiates individuals with SAD from healthy participants, though evidence for the role of the fear circuit in classification has been inconsistent. We extend this literature by using SVM during direct face processing. Individuals with SAD (n=47) and healthy controls (n=46) completed a validated emotional face matching task during functional MRI, which included a matching shapes control condition. SVM was based on brain response to threat (vs. happy) faces, threat faces (vs. shapes), and threat/happy faces (vs. shapes) in 90 regions encompassing frontal, limbic, parietal, temporal, and occipital systems. Recursive feature elimination (RFE) was used for feature selection and to rank the contribution of regions in predicting SAD diagnosis. SVM results for threat (vs. happy) faces revealed satisfactory accuracy (e.g., area under the curve=0.72); results with shapes as "baseline" yielded less optimal classification. RFE for threat (vs. happy) indicated that all 90 brain regions were necessary for classification. RFE-based ranking suggested diffuse neurofunctional activation to threat (vs. happy) faces in classification. When using an RFE cut-point, regions implicated in sensory and goal-directed processes contributed relatively more in differentiating SAD from controls than other regions. Results suggest that neural activity across large-scale systems, as opposed to fear circuitry alone, may aid in the diagnosis of SAD.

Abstract
Emotion regulation deficits are commonly observed in social anxiety disorder (SAD). We used manifold-learning to learn the phase-space connectome manifold of EEG brain dynamics in twenty SAD participants and twenty healthy controls. The purpose of the present study was to utilize manifold-learning to understand EEG brain dynamics associated with emotion regulation processes. Our emotion regulation task (ERT) contains three conditions: Neutral, Maintain and Reappraise. For all conditions and subjects, EEG connectivity data was converted into series of temporally-consecutive connectomes and aggregated to yield this phase-space manifold. As manifold geodesic distances encode intrinsic geometry, we visualized this space using its geodesic-informed minimum spanning tree and compared neurophysiological dynamics across conditions and groups using the corresponding trajectory length. Results showed that SAD participants had significantly longer trajectory lengths during Neutral and Maintain. Further, trajectory lengths during Reappraise were significantly associated with the habitual use of reappraisal strategies, while Maintain trajectory lengths were significantly associated with the negative affective state during Maintain. In sum, an unsupervised connectome manifold-learning approach can reveal emotion regulation associated phase-space features of brain dynamics.

Abstract
Connectomics is a framework that models brain structure and function interconnectivity as a network, rather than narrowly focusing on select regions-of-interest. MRI-derived connectomes can be structural, usually based on diffusion-weighted MR imaging, or functional, usually formed by examining fMRI blood-oxygen-level-dependent (BOLD) signal correlations. Recently, we developed a novel method for assessing the hierarchical modularity of functional brain networks-the probability associated community estimation (PACE). PACE uniquely permits a dual formulation, thus yielding equivalent connectome modular structure regardless of whether positive or negative edges are considered. This method was rigorously validated using the 1,000 functional connectomes project data set (F1000, RRID:SCR_005361) (1) and the Human Connectome Project (HCP, RRID:SCR_006942) (2, 3) and we reported novel sex differences in resting-state connectivity not previously reported. (4) This study further examines sex differences in regard to hierarchical modularity as a function of age and clinical correlates, with findings supporting a basal configuration framework as a more nuanced and dynamic way of conceptualizing the resting-state connectome that is modulated by both age and sex. Our results showed that differences in connectivity between men and women in the 22-25 age range were not significantly different. However, these same non-significant differences attained significance in both the 26-30 age group (p = 0.003) and the 31-35 age group (p < 0.001). At the most global level, areas of diverging sex difference include parts of the prefrontal cortex and the temporal lobe, amygdala, hippocampus, inferior parietal lobule, posterior cingulate, and precuneus. Further, we identified statistically different self-reported summary scores of inattention, hyperactivity, and anxiety problems between men and women. These self-reports additionally divergently interact with age and the basal configuration between sexes.

Abstract
BACKGROUND Functional magnetic resonance imaging (fMRI) resting-state studies show generalized social anxiety disorder (gSAD) is associated with disturbances in networks involved in emotion regulation, emotion processing, and perceptual functions, suggesting a network framework is integral to elucidating the pathophysiology of gSAD. However, fMRI does not measure the fast dynamic interconnections of functional networks. Therefore, we examined whole-brain functional connectomics with electroencephalogram (EEG) during resting-state. METHODS Resting-state EEG data was recorded for 32 patients with gSAD and 32 demographically-matched healthy controls (HC). Sensor-level connectivity analysis was applied on EEG data by using Weighted Phase Lag Index (WPLI) and graph analysis based on WPLI was used to determine clustering coefficient and characteristic path length to estimate local integration and global segregation of networks. RESULTS WPLI results showed increased oscillatory midline coherence in the theta frequency band indicating higher connectivity in the gSAD relative to HC group during rest. Additionally, WPLI values positively correlated with state anxiety levels within the gSAD group but not the HC group. Our graph theory based connectomics analysis demonstrated increased clustering coefficient and decreased characteristic path length in theta-based whole brain functional organization in subjects with gSAD compared to HC. CONCLUSIONS Theta-dependent interconnectivity was associated with state anxiety in gSAD and an increase in information processing efficiency in gSAD (compared to controls). Results may represent enhanced baseline self-focused attention, which is consistent with cognitive models of gSAD and fMRI studies implicating emotion dysregulation and disturbances in task negative networks (e.g., default mode network) in gSAD.

Abstract
OBJECTIVE To investigate the current situation of family medicine stockpile and children medication in China, analyze the existing problems and provide the rationalized suggestions. METHODS The questionnaire was designed and convenient sampling survey was performed in 20 children hospitals in China. Descriptive analysis was conducted on the survey results. RESULTS A total of 13 940 completed questionnaires were returned, 98.33% of the families had medicine stockpile, the top three types of the medicine for children were cold medicine(73.95%), oral paregoric/febrifuge(48.01%)and external used drugs for skin disease(wound)(41.10%). The medicine was bought according to physician's prescription and guide(71.18%). Drug poisoning occurred in children of 238 families(1.71%), overdose use was the first cause(44.96%). 22.33% of the parents didn't read the specification carefully before medicine use. The non-appropriate medication for children were mainly the use of adult medicine(32.70%), untimely medication(30.90%), non-rational or unneeded use of febrifuge(26.35%). CONCLUSIONS In China, the families mainly store common medicine for their children. The parents bought medicine mainly according to physician' s prescription and paid attention to the safety and efficiency of the medicine, but non-appropriate use of medicine was still common. It is necessary to improve the rational use of medicine for children through expert counsel and guidance.

Abstract
This study aimed to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on learning and memory in a rat model of vascular dementia (VaD) and to analyze the associated mechanisms. Bilateral carotid artery occlusion (2-VO) was used to establish a rat model of VaD. High-frequency (5Hz) rTMS was performed on rats for four weeks. Spatial learning and memory abilities were evaluated using the Morris water maze (MWM), and synaptic plasticity in the hippocampus was assessed via long-term potentiation (LTP). Hippocampal expression of vascular endothelial growth factor (VEGF), brain-derived neurotrophic factor (BDNF) and three subunits of the N-methyl-D-aspartic acid receptor (NMDAR), NR1, NR2A and NR2B, was analyzed by Western blotting. Compared with the VaD group, escape latency was decreased (P<0.05) and the time spent in the target quadrant and the percentage of swimming distance within that quadrant were increased (P<0.05) in the rTMS group. LTP at hippocampal CA3-CA1 synapses was enhanced by rTMS (P<0.05). VEGF expression was up-regulated following 2-VO and was further increased by rTMS (P<0.05). BDNF, NR1 and NR2B expression was decreased in the VaD group and increased by rTMS (P<0.05). There were no significant differences in NR2A expression among the three groups. These results suggest that rTMS improved learning and memory in the VaD model rats via the up-regulation of VEGF, BDNF and NMDARs. In addition, NR2B may be more important than NR2A for LTP induction in the hippocampus during rTMS treatment of VaD.

Abstract
To understand the genetic mechanisms underlying the endangerment of Pinus koraiensis, we studied the mating system of 49 families of this species in 3 natural populations along its post-glacial colonization route across ~1500 km in northeastern China using the chloroplast simple sequence repeat technique. We analyzed 11 polymorphic loci with clear and repeating bands, and we calculated the multi-locus outcrossing rate (tm), single-locus outcrossing rate, inbreeding index, and fixation index (F). Intra-population variation was not observed, but a large inter-population variation was observed in the outcrossing rate, and the tm increased from 0.767 (the south population) to 0.962 (the north population) along the post-glacial colonization route. The tm values within a population did not change with time over 2 consecutive years. The F values for the 3 populations were <0, which indicates an excess of heterozygotes. The mean effective number of alleles, Shannon diversity index, and Nei's genetic diversity index did not show a south-north pattern. The north population had the highest outcrossing rate but the lowest genetic diversity. The average genetic differentiation of P. koraiensis populations was 0.1251, which was within the average range of woody plants with outcrossing and wind pollination. This study suggests that the current endangerment of P. koraiensis is not related to its genetic structure; perhaps it is mainly caused by man-made and natural disturbances such as deforestation and fire. Therefore, reducing disturbances and enhancing habitats, rather than the genetic aspects, play more important roles in the long-term protection of P. koraiensis.

Abstract
Lysosomal storage diseases (LSDs) are a large group of genetic metabolic disorders that result in the accumulation of abnormal material, such as mucopolysaccharides, glycoproteins, amino acids and lipids, within cells. Since many LSDs manifest during infancy or early childhood, with potentially devastating consequences if left untreated, timely identification is imperative to prevent irreversible damage and early death. In this review, the key imaging features of the non-lipid or extralipid LSDs are examined and correlated with salient clinical manifestations and genetic information. Disorders are stratified based on the type of excess material causing tissue or organ dysfunction, with descriptions of the mucopolysaccharidoses, mucolipidoses, alpha-mannosidosis, glycogen storage disorder II and cystinosis. In addition, similarities and differences in radiological findings between each of these LSDs are highlighted to facilitate further recognition. Given the rare and extensive nature of the LSDs, mastery of their multiple clinical and radiological traits may seem challenging. However, an understanding of the distinguishing imaging characteristics of LSDs and their clinical correlates may allow radiologists to play a key role in the early diagnosis of these progressive and potentially fatal disorders.
