Abstract
Presented here is the stepwise and one-pot synthesis of a dipyridazinamethyrin, 1. In either synthetic route, a proper metal cation template was found necessary. 1H NMR and UV-Vis absorption studies suggest this macrocycle exhibits a non-aromatic nature. DFT calculations suggest that the optimized structure of this macrocycle is slightly ruffled rather than planar.

Abstract
Background Children from socioeconomically disadvantaged families have a markedly elevated risk for impaired cognitive and social-emotional development. Children in poverty experience have a high risk for developmental delays. Poverty engenders disproportionate exposure to psychological adversity which may contribute to impaired offspring development; however the effect may be mitigated by social support and other aspects of resilience. Our objective was to determine the association between maternal stress, adversity and social support and early infant neurobehavior and child behavior at two and three years. Methods We conducted a longitudinal mother-infant cohort study nested within a regional home visiting program in Cincinnati, Ohio. Four home study visits were completed to collect measures of maternal stress, adversity and social support and infant and child behavior. A measure of infant neurobehavior (‘high-arousal’ infant) was derived from the NICU Network Neurobehavioral Scale (NNNS) at 1 month and externalizing and internalizing symptoms were measured by the Child Behavior Checklist (CBCL) at 24 and 36 months. Linear and logistic regression identified associations between maternal risk/protective factors and infant and child behavioral measures. We used stratification and multiplicative interaction terms to examine potential interactions. Results We enrolled n = 55 pregnant mothers and follow 53 mother–offspring dyads at 1 month, 40 dyads at 24 months and 27 dyads at 36 months. Maternal adversity and protective factors were not associated with neurobehavior at one month. However, maternal depression and measures of distress in pregnancy were significantly associated with internalizing and externalizing symptoms at 24 and 36 months. Conclusions This pilot study established the feasibility of conducting longitudinal research within a community intervention program. In addition, although there were no statistically significant associations between maternal psychosocial factors in pregnancy and infant neurobehavior, there were several associations at 24 months, primarily internalizing symptoms, which persisted through 36 months. Future work will replicate findings within a larger study as well as explore mediators and modifiers of these associations.

Abstract
Abstract
Background
The incidence of atrioventricular reentrant tachycardia (AVNRT) in pulmonary arterial hypertension (PAH) patients is higher than the general population [1–3]. AVNRT had been reported with larger coronary sinus (CS) ostium in general population, while the mechanism and correlation between AVNRT and the CS ostium in PAH patients are poorly understood.
Purpose
We aim to investigate the impact of the CS ostium on AVNRT and find out its risk factors in PAH patients.
Methods
Of 102 pulmonary arterial hypertension (PAH) patients with catheter ablation of SVT, 10 patients confirmed AVNRT who underwent computed tomographic angiography (CTA) were enrolled as study group. The control group (PAH patients without SVT, n=20) were matched in a ratio of 2:1 based on gender and BMI. We measured maxium diameter of CS ostium in axial and LAO plane by CTA. All baseline characteristics and imaging materials were collected.
Results
PAH patients with AVNRT were older (45.9±14.8 vs. 32.1±7.6 years, P=0.025) and more likely to have larger CS ostium in LAO plane (18.6±3.3 vs. 14.8±4.0 mm, P=0.011) than those without AVNRT. The maximal diameter of CS ostium in LAO plane was an independent predictor for AVNRT in PAH patients (Odds ratio, 1.389; 95% confidence interval, 1.003–1.923; P=0.048). The cut-off value of CS ostium in LAO plane was 14.1mm (Area under curve = 0.79, P=0.012), and the sensitivity and specificity were 90% and 55%, respectively.
Conclusions
The larger CS ostium in LAO plane correlated with the higher prevalence of AVNRT in PAH patients with age. Patients with CS ostium larger than 14.1mm in LAO plane are more likely to develop AVNRT.

Abstract
Abstract
Background
A variety of supraventricular arrhythmias (SVAs) may occur in patients with hypertrophic cardiomyopathy (HCM). The characteristics and long-term ablation outcomes of different types of SVAs in HCM have not been comprehensively investigated.
Methods
We retrospectively enrolled 101 consecutive symptomatic HCM patients with suspected arrhythmia from May 2010 to October 2020. The clinical features and ablation outcomes of patients with SVAs were further analyzed.
Results
Seventy-eight patients had SVAs, consisting of 50 (64.1%) atrial fibrillation (AF), 16 (20.5%) atrial flutter (AFL), 15 (19.2%) atrioventricular reentrant tachycardia (AVRT), 11 (14.1%) atrial arrhythmia (AT), and 3 (3.8%) atrioventricular nodal reentrant tachycardia (AVNRT). Thirty-four patients underwent catheter ablation including 14 for AF, 9 for AVRT, 6 for AFL, 3 for AVNRT, 1 for both AF and AFL, and 1 for both AF and AVRT. They were followed up for a median (interquartile range) of 58.5 (82.9) months. There were no recurrences for patients with non-AF SVAs. For patients with AF, the 1- and 7-year AF-free survival were 87.5% and 49.5%, respectively. A ROC analysis revealed that a greater left ventricular end-diastolic dimension (LVEDD) was associated with higher recurrence of AF with an optimum cutoff value of 47mm (c-statistic = 0.91, p=0.011, sensitivity = 1.00, specificity = 0.82). In Kaplan-Meier analysis, patients with LVEDD ≥47mm had worse AF-free survival (log-rank p=0.014).
Conclusions
AF is the most common SVA in HCM, with AFL, AVRT, AT, and AVNRT ranking the second to the last according to the prevalence. The long-term catheter ablation outcome for non-AF SVAs in HCM is satisfying. A greater LVEDD predicts AF recurrence after catheter ablation in patients with HCM.

Abstract
Diabetes is a common and complex disease that can exacerbate the complications related to cardiovascular disease, and this is especially true for type 2 diabetes mellitus (T2DM). In addition to the standard pharmacological therapies, T2DM has also been treated with nonconventional regimens such as traditional Chinese medicine (TCM), e.g., herbal medicines and TCM prescriptions, although the mechanisms underlying the therapeutic benefits remain unclear. In this regard, many studies have used metabolomics technology to elucidate the basis for the efficacy of TCM for T2DM. Metabolomics has recently attracted much attention with regard to drug discovery and pharmacologically relevant natural products. In this review, we summarize the application of metabolomics to the assessment of TCM efficacy for treating T2DM. Increasing evidence suggests that the metabolic profile of an individual patient may reflect a specific type of T2DM syndrome, which may provide a new perspective for disease diagnosis. In addition, TCM has proved effective for countering the metabolic disorders related to T2DM, and this may constitute the basis for TCM efficacy. Therefore, further determining how TCM contributes to the reversal of metabolic disorders, such as using network pharmacology or by assessing the contribution of host–gut microbiota interactions, will also provide researchers with new potential targets for pharmacologic-based therapies.

Abstract
Obesity, generally characterized by excessive lipid accumulation, is a metabolic threat worldwide due to its rapid growth in global prevalence. Ginsenosides are crucial components derived from natural plants that can confer metabolic benefits for obese patients. Considering the low bioavailability and degradable properties of ginsenosides in vivo, it should be admitted that the mechanism of ginsenosides on anti-obesity contribution is still obscure. Recently, studies have indicated that ginsenoside intervention has beneficial metabolic effects on obesity and its complications because it allows for the correction of gut microbiota dysbiosis and regulates the secretion of related endogenous metabolites. In this review, we summarize the role of gut microbiota in the pathogenetic process of obesity, and explore the mechanism of ginsenosides for ameliorating obesity, which can modulate the composition of gut microbiota by improving the metabolism of intestinal endogenous substances and alleviating the level of inflammation. Ginsenosides are expected to become a promising anti-obesity medical intervention in the foreseeable clinical settings.

Abstract
Renal transporters involved in tubular excretion pathway are considered to be the key concern in drug evaluations in nephrotoxicity. However, the relationship between the alternation of renal transporters and the kinetic process of vancomycin (VCM)-induced nephrotoxicity has not been fully elucidated. The present study investigated the alteration of renal transporters expression in the kinetic process of VCM-induced nephrotoxicity in mice. C57BL/6 mice were administrated with normal saline or VCM for 7 days. Biochemical and pathological analyses were conducted to investigate the nephrotoxicity induced by VCM administration. Renal oxidative status, plasma, and kidney content of VCM were monitored. Quantitative real-time polymerase chain reaction and immunohistochemistry analyses were performed to analyze the expression of renal transporters. Finally, our data showed that the exposure of VCM (400 mg/kg) caused a slight nephrotoxicity in mice, whereas exposure of VCM (600 mg/kg) resulted in the severe nephrotoxicity in mice as evidenced by biochemical parameters and renal morphological changes. In addition, the accumulation of VCM in kidney is higher than plasma. Interestingly, VCM (600 mg/kg, body weight) resulted in the induction of Oct2-Mate1 and Oat1/3-Mrp2/Mrp4/Bcrp pathways. However, VCM (400 mg/kg, body weight) caused the induction of Oct2-Mate1/Mate2 and Oat1/3-Mrp4/Bcrp pathways. The changes of renal transporters in association with the kinetic process of VCM-induced nephrotoxicity may exert important practical implications for its optimal use in clinic.

Abstract
Porphysomes (PS) are liposome-like nanoparticles comprising pyropheophorbide-conjugated phospholipids that have demonstrated potential as multimodal theranostic agents for applications that include phototherapies, targeted drug delivery and in vivo fluorescence, photoacoustic, magnetic resonance or positron emission imaging. Previous therapeutic applications focused primarily on photothermal therapy (PTT) and suggested that PSs require target-triggered activation for use as photodynamic therapy (PDT) sensitizers. Here, athymic nude mice bearing subcutaneous A549 human lung tumors were randomized into treatment and control groups: PS-PDT at various doses, PS-only and no treatment negative controls, as well as positive controls using the clinical photosensitizer Photofrin. Animals were followed for 30 days post-treatment. PS-PDT at all doses demonstrated a significant tumor ablative effect, with the greatest effect seen with 10 mg/kg PS at a drug-light interval of 24 h. By comparison, negative controls (PS-only, Photofrin-only, and no treatment) showed uncontrolled tumor growth. PDT with Photofrin at 5 mg/kg and PS at 10 mg/kg demonstrated similar tumor growth suppression and complete tumor response rates (15 vs. 25%, p = 0.52). Hence, porphysome nanoparticles are an effective PDT agent and have the additional advantages of multimodal diagnostic and therapeutic applications arising from their intrinsic structure. Porphysomes may also be the first single all-organic agent capable of concurrent PDT and PTT.

Abstract
PURPOSE The '5-2-1-0' guidelines recommend that children: eat ≥5 servings of fruits/vegetables ('5'), have ≤2 hours of screen-time ('2'), have ≥1 hour of activity ('1'), and drink 0 sugar-sweetened beverages ('0') daily. The pediatric emergency department (PED) treats children at risk for obesity and tobacco smoke exposure (TSE). We examined body mass index (BMI), overweight, obesity, TSE, and '5-2-1-0' rates in children with TSE in the PED. DESIGN Cross-sectional study of PED children. SETTING The PED of a children's hospital. SAMPLE Children with TSE >6 months-5 years old (N = 401). MEASURES Sociodemographics, '5-2-1-0' behaviors, BMI, and cotinine-confirmed TSE. ANALYSIS Associations between '5-2-1-0' and sociodemographics were examined with logistic regression. RESULTS Mean (SD) age = 2.4 (1.6) years; 53.1% were Black; 65.8% had low-income; and 93.4% had TSE. Of 2-5-year-olds, mean (SD) BMI percentile was 66.2 (30.1), 16.1% were overweight and 20.6% were obese. In total, 10.5% attained '5', 72.6% attained '2', 57.8% of 2-5-year-olds attained '1', and 9.8% attained '0'. Compared to White children, "other" race children were more likely to meet '5' (aOR(95% CI):4.67(1.41, 5.45)); 2-5-years-olds (aOR(95%CI):0.60(0.38, 0.95)) and Black children (aOR(95%CI):0.36(0.21, 0.60)) were at decreased odds to meet '2' compared to younger or White children, respectively. Compared to younger children, 2-5-year-olds were at decreased odds to meet '0' (aOR(95%CI):0.08(0.02, 0.26)). CONCLUSION Racially diverse, low-income children with TSE had low '5-2-1-0' attainment. Interventions are needed to improve lifestyle habits in this population.

Abstract
Objective: To evaluate the relationship between serum folate and the prognosis of cervical intraepithelial neoplasia grade I (CIN1) and the interaction between folate and high risk human papillomavirus (HR-HPV) infection. Methods: From a community-based married women cohort established in Jiexiu and Yangqu County of Shanxi Province from June to December 2014, a total of 564 eligible women with CIN1 by pathologically diagnosed were recruited. The pathological examination was performed again 12 months later. According to the prognosis of CIN1, participants were divided into CIN1 regression group, persistence and progression group, respectively. Nested case-control study was used to explore the relationship between serum folate and CIN1 prognosis, and additive model was used to analyze the interaction between serum folate and HR-HPV infection. Results: Among 564 CIN1 patients, 479 cases underwent pathological examination again, 331 were divided in CIN1 regression group and other 148 in persistence and progression group. The levels of serum folate in CIN1 regression group and persistence and progression group were (18.890±8.360) and (15.640±5.550) nmol/L, respectively, and the difference was statistically significant (Z=-6.937, P<0.001). HPV infection was detected in 154 patients, including 148 cases of HR-HPV infection and 6 cases of low risk human papillomavirus (LR-HPV) infection. Univariate analysis showed that there were significant differences in the age, passive smoking, frequency of pudendal cleaning, frequency of cleaning after sex, frequency of changing underwear, serum folate and HR-HPV infection between regression group and persistence and progression group (P<0.05). Multivariate logistic regression analysis showed that the frequency of pudendal cleaning (OR=0.422, 95%CI: 0.238-0.750), frequency of changing underwear (OR=0.574, 95%CI: 0.355-0.928), serum folate (13.06-16.78nmol/L: OR=4.806, 95%CI: 2.355-9.810; ≤13.05nmol/L: OR=8.378, 95%CI: 4.024-17.445), HR-HPV infection (OR=1.852, 95%CI: 1.170-2.933) were the independent influencing factors of CIN1 prognosis. Interaction analysis showed that the relative excess risk of low serum folate level and HR-HPV infection for the CIN1 persistence and progression was 4.992 (95%CI: 0.189-9.796), attributable proportion due to interaction was 0.552 (95%CI: 0.279-0.824), synergy index was 2.632 (95%CI: 1.239-5.588), aOR of serum folate≤16.78 nmol/L and HR-HPV infection positive was 9.055 (95%CI: 4.878-16.807). Conclusion: Low serum folate level could increase the risk of CIN1 persistence and progression, and might enhance the risk when combined with HR-HPV infection.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) as a fatal epidemic has swept across the world, especially in India where the epidemic situation is the most serious. For COVID-19 patients, pulmonary rehabilitation training plays a significant role. However, it is still a controversial issue regarding the efficacy of WeChat APP-based pulmonary rehabilitation training in improving lung function, quality of life and bad mood of COVID-19 patients. To clarify this issue, a meta-analysis was conducted in this present study, so as to provide a basis for rehabilitation guidance of COVID-19 patients. METHODS We systematically searched PubMed, medRxiv, Web of Science, Scopus, Chinese Science Citation Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wan-fang databases in May 2021 to identify randomized controlled trials and evaluate the effects of WeChat APP-based pulmonary rehabilitation training for COVID-19. Two researchers independently carried out data extraction. On the other hand, literature quality evaluation on the quality and meta-analysis of the included literature was performed with Revman5.3 software. RESULTS The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION This study will provide reliable evidence-based evidence on the effects of WeChat APP-based pulmonary rehabilitation training on lung function, bad mood, and quality of life in patients with COVID-19. ETHICS AND DISSEMINATION Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. OSF REGISTRATION NUMBER DOI 10.17605/OSF.IO/MKXCH.

Abstract
BACKGROUND Mosquito-borne diseases affect over half of the human population globally. Multiple studies have shown that chemical insecticides are ineffective because of resistance. Therefore, environmentally safe mosquito population control tools need to be developed. Ribonucleic acid interference (RNAi) is a reverse genetic mechanism recently introduced as a new pest control tool. This technique represents a new class of biorational technology that could combat the increased global incidence of insecticide resistance. The technique has the potential of becoming a critical component of integrated vector control programs. METHODS A 3-hydroxykynurenine transaminase (3-HKT) RNAi expression plasmid was constructed, generated and transformed into Chlamydomonas and Chlorella algae. The transgenic algae were then used to feed Ae. aegypti mosquito larvae. The feeding experiments were conducted on a small and large scale with 10 and about 300 larvae, respectively. The mortality rate of the larvae was calculated over 30 days. In addition, histological examination of the insect tissues was performed to examine the extent of tissue damage. RESULTS The integumentary system and midguts of larvae fed with transgenic Chlamydomonas were severely damaged. The mortality rate of the larvae fed with transgenic Chlamydomonas ranged from 60 to 100% in small-scale tests. The survival rate of adult mosquitoes was 0.0% in a large-scale feeding experiment when the larvae were fed with transgenic Chlamydomonas. Moreover, when the larvae were fed with transgenic Chlorella, the mortality rate ranged from 6.7% to 43% compared to that fed wild-type Chlorella. CONCLUSIONS 3HKT RNAi transgenic algae are in some scales lethal to Ae. aegypti. The findings of this study indicate that technology based on microalgae RNAi may provide a new way to control mosquito populations.

Background
We examined changes in quality of life (QOL) of patients after transcatheter aortic valve implantation (TAVI).
Methods
We conducted an observational cohort study of consecutive patients who had TAVI between 2016-2019 in British Columbia, Canada. QOL was measured at baseline, 30-day and 1-year using the Kansas City Cardiomyopathy Questionnaire (KCCQ-OS). We used linear regression modelling to examine factors associated with 30-day changes in QOL, logistic regression modelling to identify predictors of having a poor outcome, and Cox regression modelling to ascertain risk estimates of the effect of QOL on 1-year mortality.
Results
The cohort included 1,706 patients [742 women (43.5%)]; median [interquartile range, IQR] age 83 (77,86). Median (IQR) baseline KCCQ-OS was 45 (28.2,67), indicating severe impairment. Patients alive at 1-year (91.3%) reported a mean improvement of 24.1 (95% CI, 22.7-25.6) points in the KCCQ-OS at 30-day, which was sustained at 1-year (25.3; 95% CI, 23.8,26.8). Older age, lower baseline health status, lower aortic valve gradient, lower hemoglobin, atrial fibrillation and non-transfemoral access were associated with worse 30-day QOL. At 1-year, 65% of patients had a favourable outcome; additional risk factors for 1-year mortality (8.7%) were male sex, NYHA Class IV, severe pulmonary and renal disease, diabetes, and in-patient status.
Conclusions
TAVI is associated with significant early improvement in QOL which is sustained at 1 year in a "real world" registry. The inclusion of QOL can support treatment decision and the patient-centred evaluation of TAVI

Guided Relaxation-Based Virtual Reality for Acute Postoperative Pain and Anxiety in a Pediatric Population: Pilot Observational Study. J Med Internet Res 2021; 23:e26328. [PMID: 34048358 PMCID: PMC8314162 DOI: 10.2196/26328] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/02/2021] [Accepted: 05/04/2021] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Distraction-based therapies, such as virtual reality (VR), have been used to reduce pain during acutely painful procedures. However, distraction alone cannot produce prolonged pain reduction to manage sustained postoperative pain. Therefore, the integration of VR with other pain-reducing therapies, like guided relaxation, may enhance its clinical impact. OBJECTIVE The goal of this pilot study was to assess the impact of a single guided relaxation-based VR (VR-GR) session on postoperative pain and anxiety reduction in children. We also explored the influence of pain catastrophizing and anxiety sensitivity on this association. METHODS A total of 51 children and adolescents (7-21 years) with postoperative pain and followed by the Acute Pain Service at Cincinnati Children's Hospital were recruited over an 8-month period to undergo a single VR-GR session. Prior to VR, the patients completed 2 questionnaires: Pain Catastrophizing Scale for Children (PCS-C) and the Child Anxiety Sensitivity Index (CASI). The primary outcome was a change in pain intensity following the VR-GR session (immediately, 15 minutes, and 30 minutes). The secondary outcomes included changes in pain unpleasantness and anxiety. RESULTS The VR-GR decreased pain intensity immediately (P<.001) and at 30 minutes (P=.04) after the VR session, but not at 15 minutes (P=.16) postsession. Reductions in pain unpleasantness were observed at all time intervals (P<.001 at all intervals). Anxiety was reduced immediately (P=.02) but not at 15 minutes (P=.08) or 30 minutes (P=.30) following VR-GR. Patients with higher CASI scores reported greater reductions in pain intensity (P=.04) and unpleasantness (P=.01) following VR-GR. Pain catastrophizing was not associated with changes in pain and anxiety. CONCLUSIONS A single, short VR-GR session showed transient reductions in pain intensity, pain unpleasantness, and anxiety in children and adolescents with acute postoperative pain. The results call for a future randomized controlled trial to assess the efficacy of VR-GR. TRIAL REGISTRATION ClinicalTrials.gov NCT04556747; https://clinicaltrials.gov/ct2/show/NCT04556747.

Abstract
Abstract
Background: Accumulation of systemically administered nanoparticles (NPs) in lymph nodes has been exploited clinically for diagnostic imaging (e.g., USPIOs for lymph node metastasis) and therapeutic applications (e.g., vaccine delivery). However, the combination of diagnostic and therapeutic functionalities into a single theranostic NP has obliged undesirable trade-offs between either the imaging or drug delivery of the NP and their specific accumulation in lymph nodes. To overcome these trade-offs, we conducted a screen of various lipid-based theranostic NPs focusing on differing NP design and their resulting pharmacokinetic behaviours in healthy and diseased lymph node models.
Methods: Lipid-based theranostic NPs with varying physicochemical characteristics (e.g., formulation, size and morphology, surface targeting, etc.) were prepared with positron emitting Cu-64 and administered systemically at equivalent NP doses in healthy and diseased rodent models (i.e., mice and rats). NP types were assessed for time-dependent accumulation in major lymph node basins via non-invasive whole-body PET/MR imaging at two or more timepoints per animal. 72-hours post-injection the animals were sacrificed, and lymph nodes and major organs were excised for gamma counting and pathological evaluation. Pharmacokinetic behaviour of NPs in healthy versus diseased lymph nodes were calculated in individual animals and in naïvely pooled datasets using non-compartmental analysis.
Results: Preliminary analysis identified a leading NP candidate with specific lymph node targeting in healthy and diseased rodents: a discoidal, 35-nm peptide-targeted HDL-mimetic. In comparison with a spherical, 100-nm PEGylated NP, the discoidal NP obtained greater absolute (%ID) and relative (%ID/g) amounts of injected dose in anatomically matched lymph nodes than the spherical NP, regardless of lymph node pathology. At greatest measured concentration in healthy lymph nodes, typically 24-hpi, the differences between the discoidal and spherical NPs were on average 3-fold greater (2.893 vs. 0.864, %ID/g). Differences in other pharmacokinetic parameters such as AUC (%ID/g*h) and MRT (h) were equally pronounced.
Conclusions: Our preliminary analysis uncovered a discoidal, peptide-targeted HDL-mimetic with remarkable accumulation in lymph nodes of healthy and diseased models. Future investigations will focus on the biochemical and cellular mechanisms underlying their unique lymphatic pharmacokinetics. These preliminary results provide key insights for design of theranostic NPs for non-invasive imaging and staging lymph node pathologies, and for applications in delivery of therapeutics to lymph nodes following systemic administration.

Abstract
Retroesophageal or retrotracheal left brachiocephalic vein (LBCV) is a rare anatomic variant that is often associated with congenital heart disease. It is rarely reported in fetal life, and an isolated fetal retroesophageal LBCV has a good prognosis: it is typically asymptomatic, although respiratory symptoms or swallowing disorders occasionally occur. A variant was observed on fetal echocardiography at 22+6 weeks of gestation. The 3-vessel view revealed a transverse section of a vessel to the left of the pulmonary artery. Tracing upwards along its long axis showed that the left subclavian vein joined the left internal jugular vein to form the LBCV, and tracing downwards revealed that the vessel traveled to the right and lower side, where it merged into the superior vena cava via the azygos vein behind the aortic arch. The variant was identified as retrotracheal LBCV. Three-dimensional (3D) reconstruction of fetal great vessels was performed using temporal spatial correlation imaging. The left internal jugular vein and the left subclavian vein converged into the LBCV, then bypassed behind the trachea and converged into the superior vena cava via the azygous vein. As a 3D technique, spatio-temporal image correlation (STIC) can visualize the abnormal courses of LBCV, thus improving the diagnostic accuracy. This article presents the 2-dimensional (2D) ultrasound, color Doppler, and STIC findings of an isolated retrotracheal LBCV, which may inform the sonographic diagnosis of such variants.

Abstract
BACKGROUND Social and financial hardships, combined with disease managment and environmental factors explain approximately 80% of the observed disparity in asthma-related readmissions between Black and White children. OBJECTIVE We sought to determine whether asthma-related readmissions differed by degree of African ancestry and the extent to which such an association would also be explained by socioenvironmental risk factors. METHODS This study used data from a prospective cohort study of 695 Black and White children aged 1 to 16 years with an asthma-related admission. The primary outcome was a similar readmission within 12 months. Each subject's African ancestry was determined by single nucleotide polymorphisms on a continuous scale ranging from 0 to 1 (0 = no African ancestry; 1 = 100% African ancestry). We also assessed 37 social, environmental, and clinical variables that we clustered into 6 domains (for example, hardship, disease management). Survival and mediation analyses were conducted. RESULTS A total of 134 children (19.3%) were readmitted within 12 months. Higher African ancestry was associated with asthma readmission (odds ratio 1.11, 95% confidence interval 1.05-1.18 for every 10% increase in African ancestry) with adjustment for age and gender. The association between African ancestry and readmission was mediated by hardship (sβ = 3.42, P < .001) and disease management (sβ = 0.046, P = .001), accounting for >50% of African ancestry's effect on readmission. African ancestry was no longer significantly associated with readmission (sβ = 0.035, P = .388) after accounting for these mediators. CONCLUSIONS African ancestry was strongly associated with readmission, and the association was mediated by family hardship and disease management. These results are consistent with the notion that asthma-related racial disparities are driven by factors like structural racism and social adversity.

Abstract
OBJECTIVE Virtual reality (VR) is a promising method to manage pain. Distraction-based VR (VR-D) is thought to reduce pain by redirecting attention. While VR-D can reduce pain associated with acutely painful procedures, it is unclear if VR-D can reduce pain after surgery. We assessed the ability of a single VR-D session to decrease postoperative pain and anxiety and explored if pain catastrophizing and anxiety sensitivity influenced these outcomes in children following surgery. DESIGN Single-center, prospective, pilot study. SETTING Cincinnati Children's Hospital Medical Center (CCHMC). SUBJECTS 50 children (7-21 years) with postoperative pain followed by the Acute Pain Service. METHODS Patients received one VR-D session following surgery. Prior to the session, patients completed pain catastrophizing (PCS-C) and anxiety sensitivity (CASI) questionnaires. Primary outcome consisted of changes in pain intensity following VR-D (immediately, 15, and 30 minutes). Secondary outcomes included changes in pain unpleasantness and anxiety. RESULTS VR-D use was associated with a decrease in pain intensity immediately and 15-minutes after VR-D. Reductions in pain unpleasantness were observed up to 30 minutes following VR-D. VR-D was also associated with a reduction in anxiety immediately and at 15-minutes. While patients with higher pain catastrophizing had higher baseline pain intensity and unpleasantness, they did not show larger pain reductions following VR-D compared to those with lower pain catastrophizing. CONCLUSIONS VR-D may be beneficial in transiently reducing pain intensity, unpleasantness, and anxiety in children with postoperative pain. This study informs design of larger, randomized, controlled study assessing VR-D for acute postoperative pain and anxiety management.

Abstract
Objective: To explore the effect of dietary water-soluble vitamins on the poor prognosis of low-grade cervical intraepithelial neoplasia (CINⅠ). Methods: A total of 564 participants with CINⅠ were selected from a community-based married women cohort established in 2014. The general baseline information was collected, and HPV genotyping was detected. A food frequency questionnaire was used to investigate dietary water-soluble vitamins' consumption and determine their exposure levels. The follow-up program was carried out for 12 months, and the regression, persistence, and progression of CINⅠ was determined according to histopathological results at 12-month. Results: The low-levels of dietary water-soluble vitamins could promote CINⅠ's persistence and progression, showing the increasing tendency of CINⅠ poor prognosis with the decrease of water-soluble vitamin levels. Especially folate, VB1, VB2, VB6, niacin, biotin, and VC (RR values were 15.22, 1.86, 1.92, 2.11, 2.98, 2.14, 2.19, respectively) played an important role. Considering the status of high-risk human papillomavirus (HR-HPV) infection, our results showed that the low levels of folate, niacin, biotin could promote the poor prognosis of CINⅠ. Conclusions: The low-level of dietary water-soluble vitamins could facilitate the poor prognosis of CINⅠ. In addition, folate, niacin, biotin were more effective on HR-HPV positive women.

Abstract
Objective: To investigate the diagnostic value of different vaginal micro-environmental factors in low-grade cervical intraepithelial neoplasia (CIN Ⅰ) and determine the optimal model in high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 926 women, including 623 with normal cervical (NC) condition and 303 CINⅠ patients, had undergone pathological examinations, and were enrolled in the study. All the women were from a community previously established cohort. Vaginal cleanliness, pH, H2O2, β-glucuronidase, coagulase, sialidase, and leukocyte esterase (LE) were detected by the combined detection method aerobic vaginitis/bacterial vaginosis in vaginal secretions. HPV genotyping was performed by using the flow-through hybridization technology. The data were analyzed by SAS 9.2 and SPSS 23.0. Results: The vaginal cleanliness, pH, sialidase, and LE were determined as the representative vaginal micro-environment factors by principal component analysis. Based on logistic regression theory to analyze the ROC curve, the results showed that the highest sensitivity was with pH value (76.2%), and the highest specificity was with sialidase (90.9%). The area under ROC curve were higher in combination detection modes of sialidase+LE (0.714), pH+sialidase+LE (0.719), vaginal cleanness+sialidase+LE (0.713) and pH+vaginal cleanness+sialidase+LE (0.709). According to HR-HPV infection status, the TOPSIS method was used to analyze the combined detection optimal model. Specifically, we found that the best diagnostic model was pH+sialidase +LE (Ci=0.585) in the HR-HPV positive group and vaginal cleanness+sialidase+LE (Ci=0.641) in the negative group. Conclusions: The combined detection of vaginal microenvironment factors could be used for auxiliary diagnosis for CINⅠ. It would be more effective when detecting pH, sialidase, and LE in HR-HPV positive women while vaginal cleanness, sialidase, and LE in HR-HPV negative women at the same time.

Abstract
Objective: To describe the characteristics of high-risk human papillomavirus (HR-HPV) infection and its influences by vaginal micro-environmental factors. Methods: A total of 421 women with HR-HPV infection and normal cervix diagnosed by pathology were selected from a community cohort established earlier by our research group for a 24-month follow-up. The baseline data were collected at enrollment. The vaginal micro-environmental factors were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. And the HPV was detected by using the flow-through hybridization technology. According to the HR-HPV infection status in baseline and 24 months of follow-up, with the prognosis characteristics of HR-HPV infection described, the impact of vaginal micro-environmental factors on the prognosis of HR-HPV infection was explored as well. Results: Among 390 HR-HPV infected women who completed 24 months of follow-up, the top five types of persistent HR-HPV infection rate appeared as HPV16 (24.1%), HPV58 (22.2%), HPV53 (21.7%), HPV52 (20.0%), and HPV39 (11.8%), respectively. The results showed that women with abnormal vaginal pH (aOR=1.74, 95%CI: 1.08-2.80), abnormal neuraminidase (aOR=2.70, 95%CI: 1.52-4.83), or abnormal leucocyte esterase (aOR=3.41, 95%CI: 2.13-5.44), the risk of HR-HPV persistent infection increased. The abnormalities of neuraminidase and leukocyte esterase could increase the risk of persistent infection of homotype and heterotypic HR-HPV. Conclusions: HPV16 was prone to persistent infection. Abnormalities of vaginal pH, neuraminidase, and leukocyte esterase might increase the risk of HR-HPV persistent infection. Both the abnormalities of neuraminidase and leukocyte esterase play an essential role in the HR-HPV persistent infection.

Abstract
Objective: To analyze the association of the cadmium internal exposure with chronic kidney disease (CKD) in Chinese adults aged 18 and older. Methods: A total of 9 821 adults aged 18-79 from the China National Human Biomonitoring (CNHBM) from 2017 to 2018 were included. Blood and urine cadmium exposure levels were measured by inductively coupled plasma mass spectrometry (ICP-MS), and urine cadmium levels were adjusted with urine creatinine; CKD were defined by estimated glomerular filtration (eGFR) using the chronic kidney disease epidemiology collaboration (CKD-EPI). Weights were considered due to complex sampling process for in statistical analysis. Logistic regression is used to analyze the association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine exposure levels with CKD, and restricted cube spline (RCS) was used to assess the exposure-response curve of blood cadmium, urine cadmium and urine cadmium adjusted with creatinine with CKD. Results: The weighted age was 44.75 and males accounted for 61.1%. The prevalence rate of CKD was 12.7%. The geometric mean values of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine were 0.96 μg/L, 0.61 μg/L, and 0.58 μg/g. After adjusting for confounding factors, the weighted logistic regression showed that the lowest quintile (Q1) was compared with the odds ratio (OR) of the highest quintile (Q5) of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine and the 95% confidence interval (CI) was 1.80 (1.02-3.20), 1.77 (0.94-3.31) and 1.94 (1.11-3.37) respectively. In the restricted cubic spline regression model, non-linear association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine with CKD were observed after adjusting for related confounding factors (P<0.001, 0.018, 0.031 respectively). The risk of CKD increased with the increment of cadmium exposure without risk threshold, and the exposure response curve was steeper at low cadmium exposure. Conclusions: Among Chinese adults aged 18 and older, cadmium exposure is positively associated with the risk of chronic kidney disease.
