Following brief exposure to endogenous atherogenic particles, such as oxidized low-density lipoprotein (oxLDL), monocytes/macrophages can adopt a long-term pro-inflammatory phenotype, which is called trained immunity. This mechanism might contribute to the chronic low-grade inflammation that characterizes atherosclerosis. In this study, we aim to elucidate immunometabolic pathways that drive oxLDL-induced trained immunity. Primary isolated human monocytes were exposed to oxLDL for 24 h, and after five days stimulated with LPS to measure the cytokine production capacity. RNA-sequencing revealed broad increases in genes enriched in mitochondrial pathways after 24 h of oxLDL exposure. Further omics profiling of oxLDL-trained macrophages via intracellular metabolomics showed an enrichment for tricarboxylic acid (TCA) cycle metabolites. Single cell analysis revealed that oxLDL-trained macrophages contain larger mitochondria, potentially likely linked to increased oxidative phosphorylation (OXPHOS) activity. Co-incubation with pharmacological blockers of OXPHOS inhibited oxLDL-induced trained immunity. The relevance of OXPHOS was confirmed in a cohort of 243 healthy subjects showing that genetic variation in genes coding for enzymes relevant to OXPHOS correlated with the capacity of monocytes to be trained with oxLDL. Interestingly, OXPHOS appears to play an important role in the increased cytokine hyperresponsiveness by oxLDL-trained macrophages. The TCA-cycle can also be fuelled by glutamine and free fatty acids, and pharmacological blockade of these pathways could prevent oxLDL-induced trained immunity. This study demonstrates that the mitochondria of oxLDL-trained macrophages undergo changes to their function and form with OXPHOS being an important mechanism for trained immunity, which could unveil novel pharmacological targets to prevent atherogenesis.A 54-year-old man presented with a pathologic hip fracture secondary to a right femur tumor. this website A reaming biopsy showed the diagnosis of dedifferentiated chondrosarcoma (DDC). In addition, the patient had a thyroid mass. Fine needle aspirate from the thyroid mass revealed numerous large fragments of cohesive spindle cells with moderate nuclear atypia and brisk mitosis, identical to the femur tumor. Immunohistochemical staining on cell blocks of thyroid aspirate showed positivity for mesenchymal markers and negativity for epithelial and thyroid markers. The metastasis of DDC to the thyroid gland is a very rare incident and has previously been described once in the literature. In this report, we describe the clinical and pathologic findings of this case.

Glucose testing at six weeks after delivery has been recommended by the World Health Organization as the earliest period to detect abnormal glucose tolerance among women with gestational diabetes mellitus (GDM). However, the rate of postpartum glucose testing in many parts of the world is low, between 30-60%. Therefore, we sought to determine the proportion of women with GDM who underwent glucose testing at six weeks postpartum and the factors associated with the compliance to the test.

We conducted a cross-sectional study between January and April 2017 in 13 governmental primary health care clinics in the southern part of Peninsular Malaysia. All eligible postpartum women registered from January to June 2016 who had GDM during their most recent pregnancy were included. Descriptive and multiple logistic regression analyses were performed.

Out of 341 women, 35.8% attended primary health care clinics for glucose testing six weeks postpartum. The factors significantly associated with the compliance to postpartum glucose testing were GDM diagnosis in previous pregnancy (adjusted odds ratio (AOR) = 1.76; 95% confidence interval (CI) 1.04-2.99;

0.036) and normal level of glycated hemoglobin during the most recent pregnancy (AOR = 2.49; 95% CI 1.06-5.86;

0.036).

The proportion of women with GDM who underwent postpartum glucose testing remained low. Hence, strategies should be reinforced to encourage all women with GDM to undergo postpartum glucose testing.

Any interruption in eyelid development can lead to congenital eyelid deformities. Eyelid abnormalities in children may present at birth due to abnormal embryogenesis (congenital) or may occur at a later stage as the child matures (developmental). These abnormalities, in general, can be classified into three different categories depending on the location malformation of the margins, malformation of the folds, and malformation of the position. Congenital and developmental eyelid abnormalities are among the most challenging problems encountered by ophthalmic reconstructive surgeons. Additional considerations include social factors regarding the patient's self-awareness of their deformities and associated medical issues, which often coexist and maybe multisystem in nature. This article briefly reviews eyelid embryology, the most common congenital eyelid anomalies, and the management options available to address these conditions.

Many Clinical and Translational Science Awards (CTSAs) focus their energy on operational aspects of running their hub, but may not devote enough energy and resources toward branding and effective communication. However, CTSAs have an important mission when it comes to communicating effectively with their stakeholders through social media. Using framing theory as the underpinning, the purpose of this content analysis is to investigate the ways in which CTSAs use Twitter to communicate with their various stakeholders, the type of content they post, and the type of engagement their tweets garner.

We examined 349 tweets posted from January 2019 to January 2020 from 19 CTSA Twitter accounts (sampled from a total of 35 CTSA accounts). A thematic codebook was generated using tweets randomly chosen from the sample. Content analysis was performed on the entire tweet sample by four coders using the codebook (alpha = 0.89).

CTSAs tweeted the most about events (29.8%), and the least about study recruitment (2.01%).
