Abstract
We report demonstrations of both quadrature-squeezed vacuum and photon number difference squeezing generated in an integrated nanophotonic device. Squeezed light is generated via strongly driven spontaneous four-wave mixing below threshold in silicon nitride microring resonators. The generated light is characterized with both homodyne detection and direct measurements of photon statistics using photon number-resolving transition-edge sensors. We measure 1.0(1) decibels of broadband quadrature squeezing (~4 decibels inferred on-chip) and 1.5(3) decibels of photon number difference squeezing (~7 decibels inferred on-chip). Nearly single temporal mode operation is achieved, with measured raw unheralded second-order correlations g (2) as high as 1.95(1). Multiphoton events of over 10 photons are directly detected with rates exceeding any previous quantum optical demonstration using integrated nanophotonics. These results will have an enabling impact on scaling continuous variable quantum technology.

Abstract
When preparing for the coronavirus disease 2019 pandemic and its effects on the CNS, radiologists should be familiar with neuroimaging appearances in past zoonotic infectious disease outbreaks. Organisms that have crossed the species barrier from animals to humans include viruses such as Hendra, Nipah, Severe Acute Respiratory Syndrome, and influenza, as well as bacteria and others. Brain CT and MR imaging findings have included cortical abnormalities, microinfarction in the white matter, large-vessel occlusion, and features of meningitis. In particular, the high sensitivity of diffusion-weighted MR imaging in detecting intracranial abnormalities has been helpful in outbreaks. Although the coronaviruses causing the previous Severe Acute Respiratory Syndrome outbreak and the current coronavirus disease 19 pandemic are related, it is important to be aware of their similarities as well as potential differences. This review describes the neuroimaging appearances of selected zoonotic outbreaks so that neuroradiologists can better understand the current pandemic and potential future outbreaks.

Abstract
We experimentally demonstrate stimulated four-wave mixing in two linearly uncoupled integrated $ {{\rm Si}_3}{{\rm N}_4} $Si3N4 micro-resonators. In our structure, the resonance combs of each resonator can be tuned independently, with the energy transfer from one resonator to the other occurring in the presence of a nonlinear interaction. This method allows flexible and efficient on-chip control of the nonlinear interaction, and is readily applicable to other third-order nonlinear phenomena.

Abstract
OBJECTIVE To investigate the role of miR-29a in regulating the differentiation mesenchymal stem cells into osteoblasts. MATERIALS AND METHODS For the first step, the changes of expression of miR-29a during the process of mesenchymal stem cells (MSCs) differentiation into osteoblast were detected. Then, we infected the MSCs with mimics or inhibitors of miR-29a to explore the roles of miR-29a in the differentiation. Further, the prediction and verification of the possible target genes of miR-29a were achieved by bioinformatics analysis and luciferase reporter assay. RESULTS MiR-29a was up-regulated during the process of MSCs differentiation into osteoblasts. Overexpression or inhibition of miR-29a using mimics or inhibitors had no significant effect on cell proliferation. Furthermore, the differentiation was enhanced when miR-29a was artificially overexpressed in vitro, whereas silencing of miR-29a attenuated this process. It was evidenced by alkaline phosphatase (ALP) staining, matrix mineralization, and increased expression of osteoblast-specific genes. Furthermore, we determined that the gene HDAC4 might be a direct target of miR-29a. CONCLUSIONS In the current study, miR-29a promotes osteogenesis via suppressing HDAC4, indicating that targeting miR-29a may be feasible in the management of osteoporosis.

Abstract
Abstract
Introduction
The cardiomyopathies (CMPs) are a diverse group of cardiac disorders and leading cause of heart failure (HF) and sudden cardiac death (SCD). Clinical courses of CMPs vary considerably even between patients with the same disease entity. The TranslatiOnal Registry for CardiomyopatHies (TORCH) is a comprehensive CMP registry that aims to provide a database and biomaterial bank for basic science and clinical research in this field. The long-term objective of this registry is to increase the understanding of disease pathomechanisms on the way to a better risk stratification as well as identification of new diagnostic and therapeutic approaches in CMP.
Methods
TORCH is a national, prospective, and multicentre registry within the German Centre for Cardiovascular Research (DZHK), which includes 2300 consecutive patients with non-ischemic (primary and secondary) CMP in 20 centres. The minimum follow up time is one year. The DZHK-wide harmonization of datasets and eCRFs (electronic case report form) were performed to ensure a high level of data quality across different study centres.
Results
Seventy percent of the enrolled patients are male. Idiopathic/familial dilated cardiomyopathy (DCM) holds the highest prevalence with 54%, followed by inflammatory DCM/myocarditis with a prevalence of 24%. Hypertrophic cardiomyopathy (HCM) is the third-most prevalent CMP in this registry (16%). Infrequent CMPs such as left ventricular non-compaction (LVNC), arrhythmogenic right ventricular cardiomyopathies (ARVC) are also represented in TORCH with a prevalence of 4% and 2% respectively. Major clinical findings are registered in TORCH. Atrial fibrillation was present with a high prevalence among all CMPs (22%-35%). The highest prevalence of stroke or TIA at baseline was reported in patients with LVNC (15.1%) and the lowest in those with amyloidosis (3.3%). Patients with ARVC had the highest number of ICD implantation and adequate ICD therapy (56.7%, p<0.05; 47.1%, p<0.05). Preliminary data analysis showed higher frequency of therapy refractory heart failure symptoms and worse outcome in patients with familial DCM in comparison to those with inflammatory or idiopathic DCM.
Conclusion and outlook
TORCH represents one of the largest cardiomyopathy registries in Europe. The patients are comprehensively phenotyped through clinical examinations, state-of-the-art imaging modalities, as well as molecular, genetic, and epigenetic investigations. This registry can help researchers design further studies investigating new diagnostic tools or therapeutic strategies in CMPs.

Abstract
BACKGROUND Portal vein embolization (PVE) is used before major hepatectomy for hepatocellular carcinoma (HCC) to increase future liver remnant (FLR) volume. However, this may increase tumour growth rate, leading to more extensive resections. This study aimed to determine the effect of tumour growth, following PVE, on treatment plan. METHOD Retrospective cohort study conducted on patients treated from 2008 to 2015 with PVE before major hepatectomy for HCC. Liver and tumour volumetry was performed on pre- and post-PVE CT scans. Image-based and actioned plans were compared before and after PVE. RESULTS Thirty-one patients received PVE. Non-tumour total liver volume decreased (median 1440 to 1394 cm3; p = 0.031), while tumour (median 161-240 cm3; p < 0.001) and FLR volumes (median 430-574 cm3; p < 0.001) increased. The treatment plan changed in 15/31 patients: more extensive resection (n = 6), less extensive resection (n = 1), no resection as scheduled (n = 8). Tumour progression accounted for a clinically relevant change in treatment plan in 8/31 patients. CONCLUSION Following PVE in the setting of HCC, tumour progression accounts for a change in treatment plan in approximately a quarter of patients. Further research is warranted to determine whether additional liver directed therapy should routinely be used to slow the growth of HCC post-PVE.

Abstract
Objective: To investigate the clinical characteristics of pertussis-associated pneumonia and analyze it's risk factors. Methods: Clinical data were taken from Shenzhen Children's Hospital with Bordetella pertussis infection and confirmed by culture or real-time polymerase chain reaction (PCR) of nasopharyngeal secretion from October 2013 to December 2015. Patients were divided into two groups, those with radiologically confirmed pneumonia in the course of their disease and those with not. Clinical data were retrospectively analyzed and compared. T test, Rank sum test or chi square test were used for comparison between groups. Risk factors were analyzed by unconditional Logistic regression analysis. Results: A total of 501 children hospitalized with Bordetella pertussis infection were included. Among them, 309 patients were diagnosed with pneumonia. The median age was 3 (2, 6) months. Symptoms were paroxysmal cough (n=252, 81.6%), tachypnea (n=69, 22.3%), and cyanosis (n=105, 34.0%). The time from onset of cough to radiologically confirmed pneumonia was between 1 and 66 days with a median of 9 (5.5, 15.0) days. The most common pathogen of coinfection was respiratory syncytial virus (RSV)(20 cases). Macrolides were used in 306 cases for (8.2±3.6) days. All cases showed significant improvement. There were more male children (62.1% (192/309) vs. 50.3% (95/189) , χ(2)=6.768, P=0.009), and more instances of comorbidities (13.3% (41/309) vs.5.8% (11/189) , χ(2)=6.957, P=0.008) in the pneumonia group than in the other. The age was younger (3 (2,6) vs.4 (2,6) months, Z=32.91, P=0.000) in pneumonia group than in the other. Male sex, younger age, and underlying disease were independent risk factors for pertussis-associated pneumonia (OR=1.648, 1.486, 2.695, P=0.008, 0.036, 0.005). Conclusions: Pneumonia, as a complication of pertussis, is very easy to see in hospitalized children. The duration of hospitalization is extensive. It is more likely to happen in children who are male, young, and having underlying diseases. Pneumonia is easy to occur in the first 2 weeks of the course of disease.

Abstract
This single-blind, pragmatic, cluster randomised controlled trial aims to investigate uptake of children's weight management services in response to enhanced National Child Measurement Programme (NCMP) letters providing weight status feedback to parents in three English counties in 2015. Parents of 2642 overweight or very overweight (obese) children aged 10-11 years received an intervention or control letter informing them of their child's weight status. Intervention letters included (i) a visual tool to help weight status recognition, (ii) a social norms statement, and for very overweight children, (iii) a prepopulated booking form for weight management services. The primary outcome was weight management service enrolment. Additional outcome measures included attendance at and contact made with weight management services, and a number of self-report variables. A small effect was observed, with intervention parents being significantly more likely to enrol their children in weight management services (4.33% of Intervention group) than control parents (2.19% of Control group) in both unadjusted (OR = 2.08, p = .008) and adjusted analyses (AOR = 2.48, p = .001). A similar picture emerged for contact with services (4.80% Intervention vs. 2.41% Control; OR = 2.10, p = .003; AOR = 2.46, p < .001) and attendance at services, although group differences in the latter measure were not significant after corrections for multiple comparisons (1.89% Intervention vs. 1.02% Control; AOR = 2.11, p = .047). No effects were found on self-report variables. Theoretically informed weight status feedback letters appear to be an effective strategy to improve enrolment in paediatric weight management services.

Abstract
Objective: To investigate frailty progress status and related factors in the elderly living in communities. Methods: A cohort of elderly people aged 65 and over in Pingyi community of Dujiangyan, Sichuan province, was established. Face-to-face questionnaire survey was conducted by trained interviewers. The frailty status, cognitive function, nutrition status and other functions of the subjects surveyed were evaluated at baseline survey and during follow-up. The socio-demographic and clinical characteristics of the subjects surveyed were assessed at baseline survey. Binary logistic regressions were used to identify factors associated with frailty progress. Results: A total of 653 elderly people were surveyed in January 2014, and 507 elderly people were followed up while 146 elderly people terminated further follow-up in January 2017. The prevalence rates of frailty and pre-frailty at baseline survey were 11.2% (n=57) and 26.2% (n=133), respectively. After 3 years, 205 subjects (40.4%) surveyed experienced frailty progress, 276 (54.5%) remained to be in frailty state at baseline survey, and 26 (5.1%) had improvement. Disability (OR=8.27, 95%CI: 1.62-42.26), visual problem (OR=2.02, 95%CI: 1.27-3.22), cognitive impairment (OR=1.94, 95%CI: 1.08-3.48), poor self-rated health (OR=1.89, 95%CI: 1.07-3.31), chronic pain (OR=1.57, 95%CI: 1.03-2.40) and older age (OR=1.12, 95%CI: 1.08-1.17) were independently associated with the progress of frailty. In contract, overweight was a protective factor (OR=0.54, 95%CI: 0.34-0.85). Conclusions: Frailty is a dynamic syndrome affected by several socio-demographic factors and geriatric factors. The results of the study can be used in the prevention of frailty progress in the elderly in communities.

Abstract
We demonstrate a system composed of two resonators that are coupled solely through a nonlinear interaction, and where the linear properties of each resonator can be controlled locally. We show that this class of dynamical systems has peculiar properties with important consequences for the study of classical and quantum nonlinear optical phenomena. As an example we discuss the case of dual-pump spontaneous four-wave mixing.

Abstract
AIMS Examine barriers for taking glucose-lowering oral medications, associated baseline characteristics, strategies used, and the adherence impact in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. METHODS We studied youth prescribed oral diabetes medications over two years (N = 611, 583, and 525 at 6, 12, and 24 months). Clinicians documented barriers (e.g. forgetting, routines, other concerns) in the subsample that reported missed doses (N = 423 [69.2%], 422 [72.4%], and 414 [78.9%] at 6, 12, and 24 months, respectively). Adherence strategies were also assessed (e.g. family, schedule, reminder device) using standard questions. Logistic regression was used to analyze associations with medication adherence. RESULTS Those missing doses were not different from the total sample (61.5% female, 13.9 ± 2.0 years, >80% racial/ethnic minorities). No baseline demographic or clinical predictors of barriers to medication adherence were identified. Among those for whom barriers were assessed, "forgetting" with no reason named (39.3%) and disruptions to mealtime, sleep, and schedule (21.9%) accounted for the largest proportion of responses. Family support was the primary adherence strategy identified by most youth (≥50%), followed by pairing the medication regimen with daily routines (>40%); the latter strategy was associated with significantly higher adherence rates (p = 0.009). CONCLUSIONS Family supported medication adherence was common in this mid-adolescent cohort, but self-management strategies were also in evidence. Findings are similar to those reported among youth with other serious chronic diseases. Prospective studies of multi-component family support and self-management interventions for improving medication adherence are warranted. TRIAL REGISTRATION ClinicalTrials.gov NCT00081328.
