6%) and had a poorer diet (32.4%). Almost one fifth (18.8%) of families reported an increase in the dosage of medication administered to their child. selleck chemicals llc Parents reported COVID-19 had impacted their own well-being (76.1%). Over half of respondents were not satisfied with services received during COVID-19 (54.8%) and just 30% reported that telehealth works well for their child.

Targeted interventions are required to address worsening child neurodevelopmental disability, mental health symptoms and poor diet, sleep and exercise patterns. Improved access to telehealth services is indicated, as is further research on barriers and enablers of effective telehealth services.

The life expectancy of people with Down syndrome (DS) has significantly increased in the last decades. We describe the congenital malformations and main comorbidities of a cohort of children and young people with DS and analyse their differences according to age and gender groups.

This retrospective cross-sectional study was conducted at DS centre of Bambino Gesù Children's Hospital in Rome (Italy). The period for reviewing all electronic health records ran from July 2016 to September 2017. We collected data on clinical conditions and compared them with the general paediatric population. Moreover, we compared the main comorbidities, dental diseases and body mass index data between age groups.

Seven hundred sixty-three children and young people with DS included in this study were aged 7.45±5.49years. Gender distribution included 58.19% male patients. The majority of our population (71.04%) came from central regions of Italy. Respiratory diseases (19%), congenital heart defects (72.23%), malocclusions (58.62%), astigmatism (20.31%), farsightedness (16.51%), near-sightedness (12.19%) and autoimmune hypothyroidism (3.28%) were more frequent in our population compared with the typical paediatric population. Upper respiratory tract infections and underweight were significantly more frequent in the youngest children, whereas dental diseases, refractive errors, obesity and autoimmune hypothyroidism increased over age.

Children and young people with DS present a high prevalence of potentially treatable medical conditions making multidisciplinary teams a mandatory need for this population.

High recurrence rates after curative resection and the lack of specific biomarkers for intrahepatic metastases are major clinical problems. Recently, exosomal microRNAs (miRNAs) have been reported to have a role in the formation of the pre-metastatic niche and as promising biomarkers in patients with malignancy. Here we aimed to clarify the molecular mechanisms of intrahepatic metastasis and to identify a novel biomarker miRNA in patients with HCC. A highly intrahepatic metastatic cell line (HuH-7M) was established by in vivo selection. HuH-7M showed increased proliferative ability and suppression of apoptosis and anoikis. HuH-7M and the parental cell (HuH-7P) showed the similar expression of epithelial-mesenchymal transition markers and cancer stem cell markers. In vivo, mice treated with exosomes derived from HuH-7M showed increased tumorigenesis of liver metastases. Exosomes from HuH-7M downregulated endothelial cell expression of vascular endothelial-cadherin (VE-cadherin) and zonula occludens-1 (ZO-1) in non-cancerous regions of liver and increased the permeability of FITC-dextran through the monolayer of endothelial cells. The miRNAs (miR-638, miR-663a, miR-3648, and miR-4258) could attenuate endothelial junction integrity by inhibiting VE-cadherin and ZO-1 expression. In patients with HCC, higher serum exosomal miR-638 expression was associated with tumor recurrence. In conclusion, the miRNAs secreted from a highly metastatic cancer cell can promote vascular permeability via downregulation of endothelial expression of VE-cadherin and ZO-1. Serum exosomal miR-638 expression holds potential for serving as a significant and independent prognostic marker in HCC.
Lung ultrasound (LUS) has received considerable interest in the clinical evaluation of patients with COVID-19. Previously described LUS manifestations for COVID-19 include B-lines, consolidations, and pleural thickening. The interrater reliability (IRR) of these findings for COVID-19 is unknown.

This study was conducted between March and June 2020. Nine physicians (hospitalists n=4; emergency medicine n=5) from 3 medical centers independently evaluated n=20 LUS scans (n=180 independent observations) collected from patients with COVID-19, diagnosed via RT-PCR. These studies were randomly selected from an image database consisting of COVID-19 patients evaluated in the emergency department with portable ultrasound devices. Physicians were blinded to any patient information or previous LUS interpretation. Kappa values (κ) were used to calculate IRR.

There was substantial IRR on the following items normal LUS scan (κ=0.79 [95% CI 0.72-0.87]), presence of B-lines (κ=0.79 [95% CI 0.72-0.87]), ≥3 B-lines observinical protocols for LUS with COVID-19 may require additional observers for the confirmation of less reliable findings such as consolidations.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection predisposes patients to arterial and venous thrombosis. This study aimed to systematically review the available evidence in the literature for cerebral venous thrombosis (CVT) in association with coronavirus disease-2019 (COVID-19).

We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases to identify cases of COVID-19-associated CVT. The search period spanned 1 January 2020 to 1 December 2020, and the review protocol (PROSPERO-CRD42020214327) followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Identified studies were evaluated for bias using the Newcastle-Ottawa scale. A proportion meta-analysis was performed to estimate the frequency of CVT among hospitalized COVID-19 patients.

We identified 57 cases from 28 reports. Study quality was mostly classified as low. CVT symptoms developed after respiratory disease in 90%, and the mean interval was 13days. CVT involved multiple sites in 67% of individuals, the deep venous system was affected in 37%, and parenchymal hemorrhage was found in 42%.
