Pathophysiology

Long-term hyperglycemia in patients with diabetes leads to human serum albumin (HSA) glycation, which may impair HSA function as a transport protein and affect the therapeutic efficacy of anticoagulants in patients with diabetes. In this study, a novel mass spectrometry approach was developed to reveal the differences in the profiles of HSA glycation sites between patients with diabetes and healthy subjects. K199 was the glycation site most significantly changed in patients with diabetes, contributing to different interactions of glycated HSA and normal HSA with two types of anticoagulant drugs, heparin and warfarin. An in vitro experiment showed that the binding affinity to warfarin became stronger when HSA was glycated, while HSA binding to heparin was not significantly influenced by glycation. A pharmacokinetic study showed a decreased level of free warfarin in the plasma of diabetic rats. A preliminary retrospective clinical study also revealed that there was a statistically significant difference in the anticoagulant efficacy between patients with diabetes and patients without diabetes who had been treated with warfarin. Our work suggests that larger studies are needed to provide additional specific guidance for patients with diabetes when they are administered anticoagulant drugs or drugs for treating other chronic diseases.

Glucagon-like peptide 1 (GLP-1) mimetics are effective drugs for treatment of type 2 diabetes, and there is consequently extensive interest in increasing endogenous GLP-1 secretion and L-cell abundance. Here we identify G-protein–coupled bile acid receptor 1 (GPBAR1) as a selective regulator of intestinal L-cell differentiation. Lithocholic acid and the synthetic GPBAR1 agonist, L3740, selectively increased L-cell density in mouse and human intestinal organoids and elevated GLP-1 secretory capacity. L3740 induced expression of Gcg and transcription factors Ngn3 and NeuroD1. L3740 also increased the L-cell number and GLP-1 levels and improved glucose tolerance in vivo. Further mechanistic examination revealed that the effect of L3740 on L cells required intact GLP-1 receptor and serotonin 5-hydroxytryptamine receptor 4 (5-HT4) signaling. Importantly, serotonin signaling through 5-HT4 mimicked the effects of L3740, acting downstream of GLP-1. Thus, GPBAR1 agonists and other powerful GLP-1 secretagogues facilitate L-cell differentiation through a paracrine GLP-1–dependent and serotonin-mediated mechanism.

Diabetes triggers peripheral nerve alterations at a structural and functional level, collectively referred to as diabetic peripheral neuropathy (DPN). This work highlights the role of the liver X receptor (LXR) signaling pathway and the cross talk with the reactive oxygen species (ROS)–producing enzyme NADPH oxidase-4 (Nox4) in the pathogenesis of DPN. Using type 1 diabetic (T1DM) mouse models together with cultured Schwann cells (SCs) and skin biopsies from patients with type 2 diabetes (T2DM), we revealed the implication of LXR and Nox4 in the pathophysiology of DPN. T1DM animals exhibit neurophysiological defects and sensorimotor abnormalities paralleled by defective peripheral myelin gene expression. These alterations were concomitant with a significant reduction in LXR expression and increase in Nox4 expression and activity in SCs and peripheral nerves, which were further verified in skin biopsies of patients with T2DM. Moreover, targeted activation of LXR or specific inhibition of Nox4 in vivo and in vitro to attenuate diabetes-induced ROS production in SCs and peripheral nerves reverses functional alteration of the peripheral nerves and restores the homeostatic profiles of MPZ and PMP22. Taken together, our findings are the first to identify novel, key mediators in the pathogenesis of DPN and suggest that targeting LXR/Nox4 axis is a promising therapeutic approach.

With Greg Holland now signed, will he be the closer or is that still going to be Archie Bradley? Beat reporter Steve Gilbert answers this question and more from fans as Spring Training approaches.

After watching his pitchers and catchers go through their first workout Wednesday, D-backs manager Torey Lovullo said it was too early to say whether Archie Bradley, Greg Holland or Yoshihisa Hirano would be his closer come Opening Day.

It was the eighth inning of a late September game against the Dodgers when D-backs right-hander Yoan Lopez showed that not only might he have the stuff to be a future closer, but also the moxie of one as well.

As federal and state governments ramp up efforts to implement the Workforce Innovation and Opportunity Act, these fact sheets compare key characteristics of the foreign born and the U.S. born that are relevant to understanding needs for adult education and workforce training services. The fact sheets cover the United States, the 20 states and 25 counties with the largest immigrant populations, and New York City.

This report analyzes the exploitation of migrants in three spheres: the domestic care sector, the labor market, and the sex industry. It details several obstacles governments face in their efforts to weaken the "bad actors" that profit from exploitation, and shows how one of the biggest challenges facing law enforcement is that serious criminals and lawbreakers often operate on the edge of legality and exploit legal routes wherever possible.

While it has been years since the Association of Southeast Asian Nations signed accords to facilitate the movement of professionals in seven occupations, implementation of these Mutual Recognition Arrangements remains "painfully slow and uneven across countries." This final report in an MPI-Asian Development Bank series explores MRA implementation by sector, and offers recommendations to help achieve the goal of greater skill mobility in Southeast Asia.

For a growing population of migrants deported from Mexico and the United States to Central America, the conditions upon return typically are worse than when they left, setting up a revolving-door cycle of migration, deportation, and remigration. This report provides a detailed profile of reception and reintegration services offered in El Salvador, Guatemala, and Honduras to deported migrants, examining their challenges and opportunities for improvement.

OBJECTIVE

Obesity is associated with microvascular insulin resistance, which is characterized by impaired insulin-mediated microvascular recruitment. Glucagon-like peptide 1 (GLP-1) recruits skeletal and cardiac muscle microvasculature, and this action is preserved in insulin-resistant rodents. We aimed to examine whether GLP-1 recruits microvasculature and improves the action of insulin in obese humans.

Dental service leaders met with the ADA Council on Government Affairs Jan. 25 in Washington to discuss legislative and regulatory issues.

The Indian Health Service is presenting a four-part series of messages focused on their younger patients’ oral heath in honor of the February observance of National Children’s Dental Health Month.

It was a Give Kids A Smile event not only for the children of the Mississippi Band of Choctaw Indians but also no fewer than 117 Indian Health Service dental programs across 24 states that were participating in GKAS with the events alone estimated to involve 14,000 American Indian/Alaska Native children.

Dr. David P. Cappelli, Ph.D., acknowledges that as providers, we don’t often understand difficulties that some patients face to receive needed dental care.

The Association is launching in March a new online, on-demand program specifically designed to provide information — from parental leave to financial support — that is tailored to the early-career dentist’s unique work-life balance needs.

Titled “Compendium of Innovations in Oral Health Service Delivery,” the 64-page digital booklet features organizations from across the country that have found success through varied measures in expanding oral care to underserved populations.

The ADA sent a letter to the U.S. Department of Health and Human Services April 17 asking the agency to “issue federal recognition that licensed dentists may administer point of service tests authorized by the Food and Drug Administration” during the COVID-19 pandemic.
