RESUMO
Liver is the largest lymph-producing organ. In cirrhotic patients, lymph production significantly increases concomitant with lymphangiogenesis. The aim of this study was to determine the mechanism of lymphangiogenesis in liver and its implication in liver fibrosis. Liver biopsies from portal hypertensive patients with portal-sinusoidal vascular disease (n = 22) and liver cirrhosis (n = 5) were evaluated for lymphangiogenesis and compared with controls (n = 9 and n = 6, respectively). For mechanistic studies, rats with partial portal vein ligation (PPVL) and bile duct ligation (BDL) were used. A gene profile data set (GSE77627), including 14 histologically normal liver, 18 idiopathic noncirrhotic portal hypertension, and 22 cirrhotic patients, was analyzed. Lymphangiogenesis was significantly increased in livers from patients with portal-sinusoidal vascular disease, cirrhotic patients, as well as PPVL and BDL rats. Importantly, Schwann cells of sympathetic nerves highly expressed vascular endothelial growth factor-C in PPVL rats. Vascular endothelial growth factor-C neutralizing antibody or sympathetic denervation significantly decreased lymphangiogenesis in livers of PPVL and BDL rats, which resulted in progression of liver fibrosis. Liver specimens from cirrhotic patients showed a positive correlation between sympathetic nerve/Schwann cell-positive areas and lymphatic vessel numbers, which was supported by gene set analysis from patients with noncirrhotic portal hypertension and cirrhotic patients. Sympathetic nerves promote hepatic lymphangiogenesis in noncirrhotic and cirrhotic livers. Increased hepatic lymphangiogenesis can be protective against liver fibrosis.

BACKGROUND: Hybrid stage I palliation (HS1P) is an alternative approach for initial palliation in hypoplastic left heart syndrome (HLHS) patients. Unlike surgical stage I palliation where atrial septectomy is routinely performed, atrial septal intervention (ASI) during HS1P is variable. In this study, we described our experience with ASI in single ventricle (SV) patients who underwent HS1P and identified factors associated with need for ASI after HS1P. METHODS: Data were retrospectively collected for all HLHS patients who underwent HS1P at our center over the past 12 years. We evaluated ASIs performed during the HS1P (intra-HS1P ASI) and ASIs performed during the period from HS1P to the subsequent surgical stage, either interval Norwood stage I or comprehensive stage II (post-HS1P ASI). Patient factors and procedural data were compared to identify factors associated with undergoing post-HS1P ASI and the impact of ASI on patient outcomes was evaluated. RESULTS: Of 50 SV patients included, 23 (46%) underwent intra-HS1P ASI and 26 (52%) underwent post-HS1P ASI. Need for post-HS1P ASI was lower among patients who had an intra-HS1P ASI as compared to those who did not (30% vs. 70%; p = 0.005). There were no significant differences in short or Midterm outcomes between patients who underwent intra-HS1P ASI or post-HS1P ASI and their counterparts. CONCLUSIONS: ASI is common both during and after HS1P but is generally well tolerated and type of ASI does not significantly impact overall patient outcomes. Our findings suggest that the current approach of individualizing management of ASI in the HS1P population is effective and safe.

Platypnea-orthodeoxia syndrome is characterised by hypoxemia and dyspnoea while upright that resolves when supine, typically associated with an interatrial communication. We present a case of platypnea-orthodeoxia syndrome associated with a sinus venosus atrial septal defect in a patient with multiple possible aetiologies of hypoxemia, including COVID-19 infection. Cardiac catheterisation with provocative maneuvers confirmed the diagnosis and symptoms resolved following defect closure. We suggest that in patients with platypnea-orthodeoxia syndrome, it is useful to obtain haemodynamic data while supine and upright.
RESUMO
BACKGROUND: Providing high-quality psychosocial care to parents and other primary caregivers of children with cancer (henceforth referred to as caregivers) is important, given the numerous challenges associated with a pediatric cancer diagnosis and the increased risk for negative psychosocial sequelae among caregivers. The Electronic Surviving Cancer Competently Intervention Program (eSCCIP) is a psychosocial eHealth intervention for caregivers, developed using an iterative, user-centered process. METHOD: eSCCIP was tested in a single-arm pilot trial at Nemours Children's Hospital, Delaware (NCT05333601). The primary outcomes were intervention acceptability and feasibility, assessed via enrollment and retention targets, and item-level acceptability ratings. Enrollment and retention targets of 45% were set based on previous work, and an item-level acceptability threshold of 80% was set. A secondary exploratory analysis was conducted examining acute distress, anxiety, symptoms of post-traumatic stress, and family functioning. RESULTS: 44 caregivers enrolled in the study and 31 completed. The intervention was rated favorably by completers, with over 80% of the sample selecting "mostly true" or "very true" for all items of the eSCCIP Evaluation Questionnaire, which was used to assess acceptability and feasibility. Enrollment and retention rates were 54% and 70%, respectively. Exploratory psychosocial outcomes showed statistically significant decreases from pre-intervention to post-intervention for overall symptoms of post-traumatic stress disorder (PTSD), cluster D symptoms of PTSD (negative mood and cognitions), and anxiety. Small-moderate effect sizes were observed for all psychosocial outcomes of interest. CONCLUSIONS: eSCCIP is an acceptable and feasible intervention for caregivers. Results are promising regarding reductions in symptoms of post-traumatic stress and anxiety.

Objective: At the outset of the coronavirus disease 2019 (COVID-19) pandemic, health care systems rapidly implemented telehealth services to maintain continuity of type 1 diabetes care. Youth of color are more likely to have suboptimal glycemic control and may benefit most from efforts to ensure continuity of care. However, research examining the perspectives of families of youth of color regarding telehealth for pediatric type 1 diabetes care is limited. We gathered perspectives from youth of color, their caregivers, and health care providers (HCPs) on telehealth for type 1 diabetes care during COVID-19. Methods: Fifty participants (22 caregivers, 19 youth, and nine HCPs) completed semi-structured interviews conducted in English (n = 44) or Spanish (n = 6). Transcripts containing mentions of telehealth (n = 33) were included for qualitative analysis to extract themes pertaining to perceptions of type 1 diabetes care and telehealth use during COVID-19. Results: Themes related to perceptions, feasibility, and quality of telehealth diabetes care were obtained. Most families had positive perceptions of telehealth. Families and HCPs described logistical and technical challenges and noted the potential for disparities in telehealth access and use. Furthermore, caregivers and HCPs felt that the lack of in-person interaction and limited access to clinical data affected the quality of care. Conclusion: Families of youth of color with type 1 diabetes mostly had positive perceptions of telehealth but also identified issues with feasibility and quality of care. Our findings highlight a need for interventions promoting equal access to telehealth and quality care for all youth with type 1 diabetes to minimize disruptions in care.
RESUMO
Patients with d-looped transposition of the great arteries (d-TGA), especially those without an adequate atrial septal defect, can experience severe hypoxemia and hemodynamic compromise in the neonatal period. This can be mitigated by urgent balloon atrial septostomy (BAS). However, some patients with d-TGA are born at centers without this capability. The aim of this retrospective study of d-TGA patients who had urgent or emergent BAS at our institution between 2010 and 2021 was to evaluate time from birth to BAS for infants born at a tertiary care center as compared to those requiring transport from other institutions and to examine correlation between time to BAS and patient outcomes. Our primary outcome was time from birth to BAS. Secondary outcomes included hospital and ICU length of stay, mortality, and evidence of pulmonary or neurologic abnormalities including pulmonary hypertension, abnormal neuroimaging, or seizures. Of 96 patients, 67 (70%) were born at our institution. The median time to BAS was 4 h for patients born at our institution vs. 14.1 h for those born elsewhere (p < .0001). A longer time from birth to BAS was associated with longer ICU (r = 0.21, p = 0.046) and hospital length of stay (r = 0.24, p = 0.02) and increased likelihood of elevated right ventricular pressure on post-operative discharge echocardiogram (p = 0.01). There were no differences in mortality between the groups. Therefore, prenatal planning for patients with known d-TGA should include a delivery plan with access to urgent BAS.

Augmented reality (AR) visualization of 3D rotational angiography (3DRA) provides 3D representations of cardiac structures with full visualization of the procedural environment. The purpose of this study was to evaluate the feasibility of converting 3DRAs of congenital heart disease patients to AR models, highlight the workflow for 3DRA optimization for AR visualization, and assess physicians' perceptions of their use. This single-center study prospectively evaluated 30 retrospectively-acquired 3DRAs that were converted to AR, compared to Computer Models (CM). Median patient age 6.5 years (0.24-38.8) and weight 20.6 kg (3.4-107.0). AR and CM quality were graded highly. RV pacing was associated with higher quality of both model types (p = 0.02). Visualization and identification of structures were graded as "very easy" in 81.1% (n = 73) and 67.8% (n = 61) of AR and CM, respectively. Fifty-nine (66%) grades 'Agreed' or 'Strongly Agreed' that AR models provided superior appreciation of 3D relationships; AR was found to be least beneficial in visualization of aortic arch obstruction. AR models were thought to be helpful in identifying pathology and assisting in interventional planning in 85 assessments (94.4%). There was significant potential seen in the opportunity for patient/family counseling and trainee/staff education with AR models. It is feasible to convert 3D models of 3DRAs into AR models, which are of similar image quality as compared to CM. AR models provided additional benefits to visualization of 3D relationships in most anatomies. Future directions include integration of interventional simulation, peri-procedural counseling of patients and families, and education of trainees and staff with AR models.
RESUMO
Calreticulin (CRT) is a protein found mainly in the endoplasmic reticulum (ER) that maintains calcium levels and controls protein folding, but has recently been found at the cell surface, cytoplasm, and in the extracellular matrix. CRT participates in multiple physiological processes such as gene expression, the immune response, and cancer. Calreticulin has been shown to autoacetylate with the binding of preferred ligand 7,8-diacetoxy-4-methylcoumarin (DAMC). This project aims to develop a chemical biology approach to investigate importance of CRT acylating abilities on its nonendoplasmic reticulum functions by targeting the downstream substrates of CRT acetylation. Our goal was to use CRT to transfer a pentynoyl tag (using a novel ligand, DPeMC) to its substrates, which can then be used as a handle for protein identification. Molecular modelling using available data in the literature was used to approximate the binding interface between CRT and the acylation ligands. Molecular Operating Environment (MOE) software was used to perform sequence alignment, simulated annealing, positional refinement, and blind docking of acylated coumarins with the CRT model. Docking studies pointed to the P domain as the most thermodynamically and sterically favourable region for acylated coumarin binding with tryptophan residue 200 within the active site on CRT. Absorption and fluorescence spectra of all coumarin compounds in ethanol:PBS (1:9 v/v) solution were investigated. Stern-Volmer quenching constant (KSV ), binding constant (K), and number of binding sites (n) of each coumarin compound with CRT was determined. Our studies demonstrated that acyl coumarin compounds bind to CRT using a dynamic quenching mechanism, bind to a single binding site on the P domain, and that the protein-ligand interaction is spontaneous and exothermic.

BACKGROUND: Young children who stay with their families in homeless shelters face chronic challenges related to extreme poverty and acute risks from stressful events surrounding the loss of housing and move to shelter. These adversities increase the likelihood of a range of poor developmental outcomes. Consistent with the risk and resilience perspective, however, many children who experience family homelessness succeed, functioning as well or better than their non-homeless peers. As such, efforts to support resilience should consider how best to enhance protective factors, such as supportive environments within shelter settings. METHODS: With data from 60 caregivers of children ages birth to 5 years recruited from family shelters, we assessed caregivers' perceptions of community support as well as child and family well-being in terms of recent adverse experiences, parenting stress, access to social support, and child social-emotional functioning. RESULTS: Many caregivers experiencing family homelessness perceived negative aspects of the shelters where they were staying with their children. Furthermore, children whose caregivers had more negative perceptions of the shelter environment displayed worse social-emotional functioning, even when accounting for differences in parenting stress, recent family adversity, and other sources of social support. CONCLUSIONS: Because young children rely on their caregivers as primary resources for nurturance and support, we encourage family homelessness service providers to work in partnership with caregivers to create more inclusive and empowering practices within the shelter context. Doing so is likely to improve children's developmental outcomes and the overall well-being of the families.

The pressing need for SARS-CoV-2 controls has led to a reassessment of strategies to identify and develop natural product inhibitors of zoonotic, highly virulent, and rapidly emerging viruses. This review article addresses how contemporary approaches involving computational chemistry, natural product (NP) and protein databases, and mass spectrometry (MS) derived target-ligand interaction analysis can be utilized to expedite the interrogation of NP structures while minimizing the time and expense of extraction, purification, and screening in BioSafety Laboratories (BSL)3 laboratories. The unparalleled structural diversity and complexity of NPs is an extraordinary resource for the discovery and development of broad-spectrum inhibitors of viral genera, including Betacoronavirus, which contains MERS, SARS, SARS-CoV-2, and the common cold. There are two key technological advances that have created unique opportunities for the identification of NP prototypes with greater efficiency: (1) the application of structural databases for NPs and target proteins and (2) the application of modern MS techniques to assess protein-ligand interactions directly from NP extracts. These approaches, developed over years, now allow for the identification and isolation of unique antiviral ligands without the immediate need for BSL3 facilities. Overall, the goal is to improve the success rate of NP-based screening by focusing resources on source materials with a higher likelihood of success, while simultaneously providing opportunities for the discovery of novel ligands to selectively target proteins involved in viral infection.

Smooth muscle tumors represent the second most common mural mesenchymal neoplasm in the gastrointestinal tract, but established criteria for prognostic assessment of these tumors are lacking. A large cohort of surgically resected intramural gastrointestinal smooth muscle tumors from 31 institutions was analyzed to identify potential prognostic features. Pathologic features were assessed by expert gastrointestinal and/or soft tissue pathologists at each center. Immunohistochemical confirmation was required. A total of 407 cases from the esophagus (n = 97, 24%), stomach (n = 180, 44%), small bowel (n = 74, 18%), and colorectum (n = 56, 14%) were identified. Patients ranged in age from 19 to 92 years (mean 55 years), with a slight female predominance (57%). Mean tumor size was 5.4 cm, with the largest tumor measuring 29 cm. Disease progression following surgery, defined as local recurrence, metastasis, or disease-related death, occurred in 56 patients (14%). Colorectal tumors were most likely to progress, followed by small bowel and gastric tumors. None of the esophageal tumors in this series progressed. Receiver operator characteristic analysis identified optimal cutoffs of 9.8 cm and 3 mitoses/5 mm2 for discriminating between progressive and non-progressive tumors. Histologic features strongly associated with progression by univariate analysis included moderate-to-severe atypia, high cellularity, abnormal differentiation (defined as differentiation not closely resembling that of normal smooth muscle), tumor necrosis, mucosal ulceration, lamina propria involvement, and serosal involvement (P < 0.0001 for all features). Age, sex, and margin status were not significantly associated with progression (P = 0.23, 0.82, and 0.07, respectively). A risk assessment table was created based on tumor site, size, and mitotic count, and Kaplan-Meier plots of progression-free survival for each subgroup revealed progression-based tiers. Based on our findings, it appears that nonesophageal gastrointestinal smooth muscle tumors measuring >10 cm and/or showing ≥3 mitoses/5 mm2 may behave aggressively, and therefore close clinical follow-up is recommended in these cases.

AIMS: Nodular regenerative hyperplasia (NRH) and obliterative portal venopathy (OPV), entities that comprise idiopathic non-cirrhotic portal hypertension (INCPH), are under-recognised diseases of uncertain aetiology and the diagnosis can be easily missed on liver biopsy. The expression of CD34 and von Willebrand factor (vWF) in liver sinusoidal endothelial cells (LSEC) and alpha-smooth muscle actin (ASMA) in hepatic stellate cells (HSCs) is unknown in NRH and OPV. We sought to investigate the pathogenesis and potential immunomarkers that might aid in making the diagnosis of NRH and OPV. METHODS AND RESULTS: Immunohistochemical (IHC) staining for CD34, vWF and ASMA was performed in clinically and histologically well-characterised NRH (n = 15) and OPV (n = 47) liver specimens. Among the 47 OPV cases, 37 (78.7%) had concurrent features of NRH. CD34 positive staining was mainly confined to small vessels in the portal tracts and LSECs in periportal areas, a finding similar to that in non-NRH/OPV livers. However, expression of vWF in LSECs was positive in the compressed sinusoids of NRH and in a patchy or geographic pattern, particularly prominent in the perivenular areas and dilated sinusoids of OPV cases. HSCs were negative for ASMA in all NRH and OPV cases. CONCLUSION: Our findings indicate that NRH may be a subtle but common concurrent morphological feature in OPV. The aberrant expression of vWF in LSECs suggests that endothelial injury may play a role in the pathogenesis, which may thus aid in the recognition and diagnosis of NRH and OPV, particularly when confronted with otherwise apparent normal liver histology on needle biopsy.

This study assessed whether the black-white mental health epidemiologic paradox (i.e., blacks' lower or similar rates of mental disorder relative to whites) extends across 12 lifetime and past-year psychiatric disorders and whether it varies with gender. We used data from the National Comorbidity Survey Replication and the National Survey of American Life, 2001-2003 (n = 4,584 black and 6,668 non-Hispanic white persons). Results showed overwhelming evidence of the paradox across lifetime and past-year disorders for women and men. In addition, blacks' mental health advantage over whites widened after adjusting for socioeconomic factors. There was one exception: Black women experienced higher risk of lifetime posttraumatic stress disorder compared with white women. These findings provide strong evidence for the "black-white mental health paradox"; however, additional research is needed to understand black women's heightened risk for posttraumatic stress disorder.

Complex interrelationships between race, sex, obesity and depression have been well-documented. Because of differences in associations between socioeconomic status (SES) and health by race, determining the role of SES may help to further explicate these relationships. The aim of this study was to determine how race and income interact with obesity on depression. Combining data from the 2007-2014 National Health and Nutrition Examination Survey, depressive symptoms was measured with the Patient Health Questionnaire-9 and obesity was assessed as body mass index ≥30â¯kg/m2. Three-way interactions between race, income and obesity on depressive symptoms were determined using ordered regression models. Significant interactions between race, middle income and obesity (ORâ¯=â¯0.66, 95% CIâ¯=â¯0.22-1.96) suggested that, among white women, obesity is positively associated with depressive symptoms across income levels, while obesity was not associated with depression for African American women at any income level. Obesity was only associated with depressive symptoms among middle-income white men (ORâ¯=â¯1.44, 95% CIâ¯=â¯1.02-2.03) and among high-income African American men (ORâ¯=â¯4.65, 95% CIâ¯=â¯1.48-14.59). The associations between obesity and depressive symptoms vary greatly by race and income. Findings from this study underscore the importance of addressing obesity and depression among higher income African American men.

INTRODUCTION: Despite numerous federal investments, chronic disease continues to disproportionately affect certain communities across the United States. Understanding the regional distribution (including any overlaps) of factors that extend beyond built and food environments, especially factors that may adversely affect chronic disease-related behaviors, is important. This case study of Los Angeles County's geospatial landscape sought to address these gaps in research and practice. METHODS: We examined the distributions and geographic overlaps between economic hardship, psychological distress, soda consumption, and availability of publicly funded mental health facilities in 8 Service Planning Areas in Los Angeles County. We categorized the geospatial presence of each variable as low, intermediate, or high. We imported all data, collected during 2014-2018, into ArcGIS Pro version 2.3.3 to create 5 bivariate choropleth maps. RESULTS: Levels of economic hardship were not equally distributed across communities; the county was characterized by intermediate levels of soda consumption and psychological distress. Most areas had low or intermediate availability of publicly funded mental health facilities. We also found some discordance between psychological distress and availability of publicly funded mental health facilities, and between economic hardship and availability of these facilities. CONCLUSION: The need exists to address disparities in economic hardship and to increase access to publicly funded mental health supports and providers in Los Angeles County. The information collected in this case study has policy implications for health, public health, and mental health services planning at the local level.

BACKGROUND: Clear cell hidradenoma and cutaneous clear cell renal cell carcinoma (CCRCC) overlap morphologically. The distinction may be difficult in a patient with a history of CCRCC, presenting with a cutaneous nodule, potentially leading to an erroneous diagnosis. We investigated the usefulness of napsin A and paired box gene 8 (PAX-8) with previously studied markers epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA), vimentin and cluster of differentiation marker 10 (CD10) in differentiating CCRCC from hidradenoma. METHODS: We evaluated hidradenomas and cutaneous CCRCCs for immunohistochemical expression of napsin A, PAX-8, EMA, CEA, vimentin and CD10. RESULTS: PAX-8 was expressed in all CCRCCs (8/8) while negative in hidradenomas. Napsin A was negative in both hidradenomas (0/12) and CCRCCs (0/10). EMA showed membranous reactivity in 11 of 12 hidradenomas and 8 of 10 CCRCCs; and highlighted ductal epithelium in 1 of 12 hidradenomas and cystic areas in 4 of 10 CCRCCs. CD10 showed ductal expression in 3 of 12 hidradenomas and membranous staining in 8 of 9 CCRCCs. CEA highlighted ductal epithelium in 11 of 12 hidradenomas while absent in CCRCCs (0/10). Vimentin highlighted neoplastic cells in 8 of 8 CCRCCs and failed to stain the hidradenomas (0/12). CONCLUSION: A conservative immunohistochemical panel including PAX-8, vimentin and CEA allow for easy distinction of CCRCC from hidradenoma, whereas napsin A added no additional value.
RESUMO
The aims of this study were to investigate the point prevalence, and associated independent factors, for foot disease (ulcers, infections and ischaemia) in a representative hospitalised population. We included 733 (83%) of 883 eligible adult inpatients across five representative Australian hospitals on one day. We collected an extensive range of self-reported characteristics from participants. We examined all participants to clinically diagnose foot disease (ulcers, infections and ischaemia) and amputation procedures. Overall, 72 participants (9·8%) [95% confidence interval (CI):7·2-11·3%] had foot disease. Foot ulcers, in 49 participants (6·7%), were independently associated with peripheral neuropathy, peripheral arterial disease, previous foot ulcers, trauma and past surgeon treatment (P < 0·05). Foot infections, in 24 (3·3%), were independently associated with previous foot ulcers, trauma and past surgeon treatment (P < 0·01). Ischaemia, in 33 (4·5%), was independently associated with older age, smokers and past surgeon treatment (P < 0·01). Amputation procedures, in 14 (1·9%), were independently associated with foot infections (P < 0·01). We found that one in every ten inpatients had foot disease, and less than half of those had diabetes. After adjusting for diabetes, factors linked with foot disease were similar to those identified in diabetes-related literature. The overall inpatient foot disease burden is similar in size to well-known medical conditions and should receive similar attention.

Radiologists across many imaging modalities commonly encounter gallbladder adenomyomatosis. The classic imaging appearances of gallbladder adenomyomatosis are well described and confirm benignity. However, in clinical practice, adenomyomatosis can be challenging to differentiate from other gallbladder pathologies that require cholecystectomy. In this article, we describe the common and uncommon appearances of gallbladder adenomyomatosis on multimodality imaging, helping differentiate adenomyomatosis from non-benign gallbladder abnormalities. Accurately differentiating adenomyomatosis from its mimics provides the surgical team with important clinical and surgical management information, improving patient outcomes.

Objective: To describe the process of engaging community, caregiver, and youth partners in codeveloping an intervention to promote equitable uptake of the COVID-19 vaccine in non-Hispanic Black (Black) and Hispanic youth who experience higher rates of COVID-19 transmission, morbidity, and mortality but were less likely to receive the COVID-19 vaccine. Methods: A team of 11 Black and Hispanic community partners was assembled to codevelop intervention strategies with our interdisciplinary research team. We used a mixed-methods crowdsourcing approach with Black and Hispanic youth (n=15) and caregivers of Black and Hispanic youth (n=20) who had not yet been vaccinated against COVID-19, recruited from primary care clinics, to elicit perspectives on the acceptability of these intervention strategies. Results: We codeveloped five strategies: (1) community-tailored handouts and posters, (2) videos featuring local youth, (3) family-centered language to offer vaccines in the primary care clinic, (4) communication-skills training for primary care providers, and (5) use of community health workers to counsel families about the vaccine. The majority (56-96.9%) of youth and caregivers rated each of these strategies as acceptable, especially because they addressed common concerns and facilitated shared decision-making. Conclusions: Engaging community and family partners led to the co-development of culturally- and locally-tailored strategies to promote dialogue and shared decision-making about the COVID-19 vaccine. This process can be used to codevelop interventions to address other forms of public health disparities. Policy Implications: Intervention strategies that promote dialogues with trusted healthcare providers and support shared decision-making are acceptable strategies to promote COVID-19 vaccine uptake among youth from historically underserved communities. Stakeholder-engaged methods may also help in the development of interventions to address other forms of health disparities.
