Limited English proficiency (LEP) is associated with decreased access to healthcare. selleck kinase inhibitor We hypothesized that LEP children with appendicitis would experience more delays in care than EP children.

Retrospective review of patients <18 y presenting to a tertiary pediatric hospital July 2014-July 2019 with appendicitis. LEP patients were compared to EP patients. The primary outcome was appendiceal perforation. Secondary outcomes included prior pediatrician or emergency department (ED) visits without definitive management, duration of symptoms, length of stay (LOS), initial operative or non-operative management, time from presentation to operation and return to the ED within 30 d. Multivariable regression was performed to evaluate LEP as a predictor of study outcomes.

A total of 893 patients with appendicitis were identified, 15.6% (n=140) had LEP. On multivariate regression LEP was not a significant predictor of appendiceal perforation (AOR 1.20, 95% CI 0.79, 1.80, P=0.390). LEP was a significant predictor of a prior ED or pediatrician visit without definitive management (AOR 2.05, 95 % CI 1.05, 3.98, P= 0.034) and longer LOS (Coefficient 1.01, 95% CI 0.41, 1.61, P= 0.001). LEP was associated with a minimal increase in duration of pain prior to presentation that was not clinically significant and was not associated with initial operative or non-operative management or a significantly longer time between presentation and operation.

LEP children did not experience higher rates of appendiceal perforation at our institution, but were more frequently initially evaluated by a pediatrician or at an ED and discharged without definitive management and had longer LOS.

Prior to the COVID-19 pandemic, the use of telemedicine to evaluate pediatric surgery patients was uncommon. Due in part to restrictions imposed to mitigate the spread of the virus, the use of telemedicine within pediatric surgery has significantly expanded.

Prior to the use of telemedicine within surgery divisions at our institution, pediatric surgeons were surveyed to determine their perspectives on the use of telemedicine. Following the expanded use of telemedicine in response to the COVID-19 pandemic, a follow up survey was distributed to determine the impact of telemedicine and the perceived benefits and barriers of continuing its use going forward.

The pre-COVID survey was completed by 37 surgeons and the post-COVID survey by 36 surgeons and advanced practice providers across 10 pediatric surgical divisions. General surgeons were the most represented division for both the pre- (25%) and post-COVID (33.3%) survey. Less than 25% of providers reported use of telemedicine at any point in their career eds and the needs of their patients and patients' families.

In clinical practice, drains had been routinely used for reducing seroma formation after breast surgery. However, an optimal timing to remove drains does not identify yet.

This study aimed to compare the clinical outcome, such as seroma formation, surgical site infection (SSI), and a length of hospital stay between early removal and late removal. A systematic review was performed using PubMed, MEDLINE, and the Cochrane Library. Breast cancer patients who received surgery using drains were eligible. Those parameters were compared between early vs late removal.

Eleven studies included in this meta-analysis. Seroma formation in the early removal group was significantly higher than the one in the late removal group (RR=1.58 95%CI [1.25-2.01], P=0.0001), meanwhile no significant difference was found among the groups for SSI (RR=0.82 95%CI [0.51-1.31], P= 0.40). A length of hospital stay in the early removal group was also significantly shorter than late removal (RR -3.31 95%CI [-5.13-1.49], P=0.0004).

Seroma formation was significantly higher in patients who had early drain removal. Conversely, SSI incidence was low, and early removal did not increase SSI incidence. In conclusion, early drain removal has no proved clinical benefit in these settings besides reduction of hospital stays.

Congenital diaphragmatic hernia (CDH) carries high morbidity and mortality, and survivors commonly have neurodevelopmental, gastrointestinal, and pulmonary sequela requiring multidisciplinary care well beyond repair. We predict that following hospitalization for repair, CDH survivors face many barriers to receiving future medical care.

A retrospective review was conducted of all living CDH patients between ages 0 to 12 years who underwent repair at Riley Hospital for Children (RHC) from 2010 through 2019. Follow-up status with specialty providers was reviewed, and all eligible families were contacted to complete a survey regarding various aspects of their child's care, including functional status, quality of life, and barriers to care. Bivariate analysis was applied to patient data (P < 0.05 was significant) and survey responses were analyzed qualitatively.

After exclusions, 70 survivors were contacted. Thirty-three (47%) were deemed lost to follow up to specialist providers, and were similar to those who maintained follow-up with respect to defect severity type (A-D, P=0.57), ECMO use (P=0.35), number of affected organ systems (P=0.36), and number of providers following after discharge (P=0.33). Seventeen (24%) families completed the survey, of whom eight (47%) were deemed lost to follow up to specialist providers. link2 Families reported distance and time constraints, access to CDH-specific information and care, access to CDH-specific resources, and access to healthcare as significant barriers to care. All respondents were interested in a multidisciplinary CDH clinic.

CDH survivors require multidisciplinary care beyond initial repair, but attrition to follow-up after discharge is high. A multidisciplinary CDH clinic may address caregivers' perceived barriers.

Few studies have investigated associations between verbal fluency performance and brain structural variation in children. Here we examined associations of verbal fluency performance with structural measures of frontal and temporal language-related brain regions and their connections in 73 typically-developing children aged 7-13 years. Tract-based spatial statistics was used to extract fractional anisotropy (FA) from the superior longitudinal fasciculus/arcuate fasciculus (SLF/AF), and the white matter underlying frontal and temporal language-related regions. FreeSurfer was used to extract cortical thickness and surface area. Better semantic and phonemic fluency performance was associated with higher right SLF/AF FA, and phonemic fluency was also modestly associated with lower left SLF/AF FA. Explorative voxelwise analyses for semantic fluency suggested associations with FA in other fiber tracts, including corpus callosum and right inferior fronto-occipital fasciculus. Overall, our results suggest that verbal fluency performance in children may rely on right hemisphere structures, possibly involving both language and executive function networks, and less on solely left hemisphere structures as often is observed in adults. Longitudinal studies are needed to clarify whether these associations are mediated by maturational processes, stable characteristics and/or experience.

Malignancy is one of the prime global causes of mortality. Cancer Patients suffering from SARS-CoV-2 have demonstrated higher rates of severe complications exacerbating towards death. Possible genetic and epigenetic alterations may exist in cancer patients which have the potential to contribute towards their increased vulnerability towards COVID-19.

An exhaustive literature search using 'COVID-19', 'SARS-CoV-2', 'Cancer', 'Malignancy', 'Relationships', Interlinks', 'Genetic', 'Epigenetic', 'Epidemiological studies', 'Clinical Studies', 'Vaccination', 'Vaccine scenario' were conducted in PubMed and EMBASE till 2nd June 2021.

In this narrative review, 17 epidemiological studies were listed which focused on clinical parameters of several malignancy patient cohorts who contracted COVID-19. Besides, genetic and epigenetic alterations seen among cancer patients are also discussed which may plausibly increase the vulnerability of cancer patients to SARS-CoV-2 infection. Also, global vaccination scenario among malignant patients along with the necessity to prioritize them in the vaccination campaigns are also elaborated.

Genetic and epigenetic modifications present in ACE2, TMPRSS2, IL-6 and several cytokines require more in-depth research to elucidate the shared mechanisms of malignancy and SARS-CoV-2.

Given the vital role of CD47 in immune response, further investigation on the regulation of CD47 in tumor microenvironment is needed. link3 Herein, we identified that interferon-gamma (IFN-γ), one of the most important cytokines in the immune and inflammatory response, up-regulated CD47 expression in cancer cells and this effect could be inhibited by the JAK1/2 inhibitor ruxolitinib, as well as siRNA-mediated silencing of JAK1, STAT1, and IRF1. The IFN-γ-induced surface expression of CD47 contributed to a stronger binding affinity to SIRPα and a decrease in phagocytosis of cancer cells by macrophages. Knockdown of JAK1, STAT1, or IRF1 by siRNA reversed the decreased phagocytosis caused by IFN-γ. Besides, analysis from TCGA revealed that IFNG had a positive correlation with CD47 in various types of cancer, which was supported by the increased surface CD47 expression after IFN-γ treatment in different types of cancer cells. The discovery of IFN-γ-induced up-regulation of CD47 in cancer cells unveils another feedback inhibitory mechanism of IFN-γ, thus providing insights into cancer immunotherapy targeting CD47.The temporal dimension of interpersonal macro- and micro-coordinations between young children and social partners, as well as its functions, has been well documented. However, the different morphologies that bodily micro-coordination can adopt during these interactions have received considerably less attention. This research studied the temporality and morphology of spontaneous child-adult micro-coordinations and their associated functions. For this purpose, three-year-old children (N = 35) were randomly assigned to storytelling sessions based on emotional or referential stories. Using motion capture technology, we traced rapid and spontaneous coordinations between torso movements, ranging from 0 to 1000 milliseconds. Results show that both mirror-like and anatomical coordinations spontaneously emerge in interactions between 3-year-old children and unfamiliar adults. Importantly, slightly delayed in time, mirror-like coordinations predominantly occur in emotional interactions, while zero-lag, anatomical coordinations occur in referential interactions.
